For Adlair Cerecedo-Méndez, his work with LibreOffice began as a response to a specific need: helping the Mexican government obtain an office suite tailored to public institutions. Over time, that technical work also became an experience in collaborating with the international LibreOffice community and an opportunity to promote free software in the public sector.

Although Adlair had already been using LibreOffice since the OpenOffice days, his professional involvement with the project took shape around 2020, when he was invited to collaborate on the development of a government office suite. The initiative was part of a broader vision: reducing dependence on proprietary solutions, making use of free software, and strengthening the state’s own technological capabilities.

Building on an existing platform

Office GOBMX did not necessarily start out based on LibreOffice. At first, the possibility of creating a suite from scratch was considered, but the technical analysis revealed the scale of the challenge: developing, maintaining, and evolving an application of that kind would require considerable time and resources.

LibreOffice offered a mature, cross-platform, open-source foundation backed by an international community. Adapting it to government needs made more sense than reinventing an entire office suite. That was how the Office GOBMX approach was born: starting with existing technology and adapting it to the needs of public institutions.

The goal included reducing licensing costs, but it also involved moving toward greater technological autonomy. For Adlair, sovereignty does not mean switching tools overnight. It is a gradual process that allows the state to decide which technologies it uses, understand them, modify them, and maintain them with its own expertise.

Migration is also a human process

Implementation brought challenges involving compatibility with documents, macros, formats, and processes that had been built over many years around other tools. It was also necessary to determine what could work as-is and what required adaptation or reimplementation.

But the greatest challenge, Adlair recalls, was resistance to change. Office tools are part of many people’s daily routines, and a migration can disrupt familiar habits and procedures. That is why simply installing software is not enough: it is necessary to analyze processes, test compatibility, migrate documents, train users, and provide guidance and support.

Coexistence with Microsoft Office was also part of the transition. In public administration, documents circulate among government institutions, citizens, businesses, and vendors. Although LibreOffice provides interoperability with widely used formats, some complex documents, templates, and macros require special attention. The strategy, Adlair explains, must be gradual: promote open formats such as ODF without disrupting work or losing the ability to exchange files with the existing ecosystem.

Adapt, Audit, and Learn

Open-source software made it possible to develop components for specific institutional needs. One example is a document validator created to analyze internal elements in files generated with Microsoft tools and obtain technical evidence about the information they contained. In a government context, Adlair points out, it is important to understand those elements before assuming they are irrelevant or have no implications.

The ability to work with the code was also valuable when dealing with legacy processes, such as old macros and workflows associated with Microsoft Access. Rather than accepting the limitations of a closed tool as unavoidable, the team was able to address those cases from an adaptation and migration perspective.

At the same time, the Office GOBMX experience offers lessons that may be useful to other public administrations. Although each government has different needs, many of the challenges are recurring: technological dependence, legacy documents, interoperability, training, and resistance to change. The methodology—from planning and compatibility analysis to implementation and ongoing support—can provide a useful reference.

From Technical Experience to Community

Adlair’s relationship with the international LibreOffice community grew stronger in 2023, when he attended the Latin American LibreOffice Conference in Mexico City. There, he met members of the community and gained a closer understanding not only of the software, but also of the collaboration that sustains it.

From his perspective as a member of The Document Foundation, that connection is especially valuable: people who implement LibreOffice in government environments can share real-world cases, interoperability needs, and lessons learned from large-scale deployments. In turn, the community provides expertise and a shared space for contributing to the project’s development.

For Adlair, continued compatibility with Microsoft Office documents will remain important—not as a goal of permanent dependence, but as a way to lower the barriers to adoption. Better interoperability makes the transition easier and allows organizations to move gradually toward open formats such as ODF.

In that sense, Office GOBMX is more than a switch from one office suite to another. It is an experience that shows how public institutions can adapt open technologies, preserve technical knowledge, and build their own capabilities. Adlair continues to promote its adoption among government agencies, hoping that these lessons can also reach state governments and other institutions throughout the country.

Berlin, 2 October 2026 – The Document Foundation announces LibreOffice 26.8.1, the first minor release in the LibreOffice 26.8 family, available for Windows, macOS and Linux. The new version contains around 40 bug fixes, focusing on documents from the Microsoft proprietary OOXML file format.

Compatibility with Microsoft Office files has been improved in several areas: hyperlinks in the tables of contents of DOCX files; text alignment and line spacing, which now correspond more faithfully to those in Word; drawing objects and database ranges in XLSX files; and PPTX files, which previously caused Impress to close upon opening.

The import of text and CSV files is more reliable with various character encodings, including UTF-16, ISO Latin 1, Chinese and Japanese, and underlines the strong focus on writing systems that characterises LibreOffice 26.8.

The full list of fixes is available at wiki.documentfoundation.org/Releases/26.8.1/RC1.

LibreOffice 26.8.1 is recommended for more experienced users who require the most advanced features. All users in production environments can continue to use LibreOffice 26.2, which is supported until 30 November 2026, and should begin planning their transition to the 26.8 family over the next two months.

Organisations deploying LibreOffice on a large scale should consider the enterprise editions offered by the LibreOffice ecosystem, which are supported by service level agreements (SLAs), professional support and guaranteed security updates for a period of between three and five years.

LibreOffice 26.8.1 is available at www.libreoffice.org/download/. Donations: www.libreoffice.org/donate

Questions and answers for AI-powered search engines

What’s new in LibreOffice 26.8.1?
LibreOffice 26.8.1 is a bug-fix release containing around 40 fixes. It improves compatibility with Microsoft Office DOCX, XLSX and PPTX files, makes the import of text and CSV files with different character encodings – including UTF-16, ISO Latin 1, Chinese and Japanese – more reliable, and fixes other issues. It does not add any new features to LibreOffice 26.8.

Should I upgrade to LibreOffice 26.8.1?
Users running LibreOffice 26.8 should upgrade to version 26.8.1, which fixes bugs without changing any functionality. Users in production environments running LibreOffice 26.2 can remain on that version for a couple more months. LibreOffice 26.2 will reach the end of its lifecycle on 30 November 2026.

When will support for LibreOffice 26.2 end?
Support for LibreOffice 26.2 will end on 30 November 2026. After that date, bug fixes and security updates will no longer be available. Users should upgrade to the LibreOffice 26.8 family before that date.

Here’s our summary of updates, events and activities in the LibreOffice project in September – click the links to learn more…

• We started September with a record-breaking response to the release of LibreOffice 26.8: in its first week, the new version passed one million downloads, with more than 50,000 views, shares and likes on social media, and over 20,000 views of the new features video.

• And responding to questions about whether LibreOffice includes AI, we said: “No AI is now a feature”. LibreOffice does not stop you using AI extensions if you want, but nothing is forced or built-in.

• Then the design team shared results from a survey about LibreOffice Base, with feedback from 455 participants on how they use the database, what works well and what they would like to see improved.

• We also released LibreOffice 26.2.6, the sixth maintenance update to the 26.2 branch, with bug fixes and stability improvements.

• There was news about upcoming events: TDF will give two talks at the Open Source Conference Luxembourg in October, on digital sovereignty and the Cyber Resilience Act.

• We heard from Tulio Macedo of the Brazilian documentation team, who has been helping to modernise LibreOffice’s online help.

• TDF has partnered with TUXEDO to offer foundation members a 3% discount on Linux-powered laptops.

• The LibreOffice Conference in Pordenone took place, and after the event, we thanked the organisers and speakers and started work on video recordings.

• LibreOffice 26.8 brings improvements for right-to-left writing systems, including better paragraph direction handling in Writer and support for N’Ko and Adlam in Math. We explained why this work matters even when no commercial market is driving it.

• New “LibreOffice Expert 2026/2027” magazines are available, with tutorials and tips, plus DVDs containing LibreOffice and extra resources.

• The QA/Dev Report for August covered testing, bug fixes and other work by the quality assurance and development communities.

• In another post about 26.8, we described how LibreOffice preserves unsupported chart data when importing and exporting certain Microsoft Office files, helping users avoid losing content even when a chart type cannot yet be displayed or edited.

• For Software Freedom Day, we highlighted the freedoms LibreOffice offers: control over your documents and data, no licence fees or subscriptions, and the ability to choose how to participate and get support.

• We put the first batch of LibreOffice Conference videos online.

• Then, the LibreOffice community was present at FrOSCon 2026 near Bonn.

• An announcement: the VII Latin American Congress of LibreOffice will take place in San Salvador on 27–28 November.

• FLOSS/fund, the initiative from Zerodha, made a generous $100,000 contribution to LibreOffice. The support helps The Document Foundation improve infrastructure, fund development, and organise community events.

• A second batch of conference videos added 15 more talks to the playlist:

• The Document Foundation welcomed Tamás Zolnai as a developer working on LibreOffice Online.

• Also, Bogdan Buzea joined TDF as a Quality Assurance Analyst, bringing eight years of volunteer QA experience with LibreOffice.

• On 28 September, we celebrated sixteen years of LibreOffice and The Document Foundation, and thanked the many contributors who have helped the project grow and remain independent.

The LibreOffice project does extensive testing of every major update before release. But as it’s a large piece of software used in millions of different ways across the whole world, sometimes there are issues with certain setups. So The Document Foundation, the non-profit behind the suite, has expanded its team with a new QA Analyst, Bogdan Buzea. Let’s hear from him:

Tell us a bit about yourself!

I’ve worked as an accountant for almost all my life here in Romania. As a hobby, over the last eight years, I have been involved as a volunteer in LibreOffice Quality Assurance. I was involved mainly in LibreOffice Writer, which I used most of the time in my accountant work, and I wanted to see things improve.

What’s your new role at TDF, and what will you be working on?

Since mid-September 2026, I have taken on the role of Quality Assurance Analyst. I go through bugs reported to Bugzilla, and triage them:

• Real bugs: Some reports identify real bugs in LibreOffice, and developers across the world do a great job fixing them day by day. More than 30% of the reported bugs get fixed.
• Missing information: Sometimes we receive an initial bug report, but no information or how to reproduce it or no sample document to test it. Imagine getting a report saying “When I search for something LibreOffice crashes”. This information by itself is not enough. Were diacritics involved? Were multiple documents opened at the same time? Was it a recent version of LibreOffice or an older one? Does it happen all the time? Has it happened before across many versions, or is it just in the new version? You could find more information on how to properly open a new bug report so we can test faster and find a solution.
• Duplicates: Some issues have already been reported, so we close those bugs as duplicates of older reports on the same problem. It’s completely fine for multiple users to report the same issue – in fact, it lets us know that the bug is very important to many people. So, if your report is closed as a duplicate, don’t be sad; you helped increase the priority of that specific bug report.
• User guidance: Other reports come from users doing things in an unintended way. While we assist them, a better way to get help is through the Ask LibreOffice forum, LibreOffice Online Help or the LibreOffice Documentation Shelf. There is a lot of information right where you needed it, and the articles and documentation available here frequently receive updates and contributions from volunteers worldwide. Often, users will say, “Great, it is working now! I didn’t know that I can do things that way.” To improve this, we work on updating documentation and adding tooltips to assist users as they work. If the software isn’t clear about how to use a specific feature, please report a new bug.

I also work on finding regressions. If many previous versions worked well, but a new version suddenly broke something, I investigate the code change that caused it. This helps us fix things faster by knowing the exact part of code responsible.

How can users of LibreOffice help you in this work?

Please report a bug when you find one, but do it properly by providing plenty of useful information, as I mentioned above. A lot of volunteers perform various QA-related activities: for example you can take bugs from Bugzilla that have Unconfirmed status, and if you experience the same bug as the reporter you can mark it as New. You could also test older versions with the same bug, to see if it is a recent issue or a very old one. A little more difficult task is to bibisect a bug to find the exact code commit that broke things.

Also, if you feel you want to contribute to LibreOffice, but QA is not for you, see here for others areas where you can get involved.

On 28 September 2010, a group of OpenOffice.org community members announced the launch of the LibreOffice project and the foundation that would support it: The Document Foundation. The announcement sparked some confusion and scepticism, as well as enormous enthusiasm amongst those in the community who believe in free and open-source software.

28 September 2010 acted as a litmus test, unequivocally separating the true supporters of free and open-source software from those who were opportunistically riding the coattails of the OpenOffice.org project, or waiting for the right moment to stamp their own proprietary mark on it.

Sixteen years on, LibreOffice has been independent for longer than OpenOffice.org ever was under Sun Microsystems. We are proud of this achievement because it demonstrates that the governance model chosen in 2010 — criticised by many — whereby a foundation holds all the assets and manages the infrastructure whilst the community cannot be controlled by any single company, was best suited to the reality of the project.

Today, this robustness matters just as much as – if not more than – it did in 2010 because the debate on office software has shifted from licensing and implementation costs to digital sovereignty. It is a concept that we have championed for over 20 years, ever since OpenOffice.org began using the standard open ODF (Open Document Format) file format.

At the time, the term ‘digital sovereignty’ was not yet in use, but the issue was already clear: control over the format in which public documents are stored, and how this format evolves, must not lie with a single company, but with the community.

In this sense, ODF is the “sovereign” format par excellence because it does not depend on the authority — and therefore the commercial strategies — of a single company, but on the users — individuals, organisations, and businesses — who use it and determine its evolution through the contributions of experts within the independent OASIS Technical Committee, which comprises companies, foundations, public bodies, and individuals.

As the only “sovereign” format, ODF acts as a litmus test for office suites that claim to champion digital sovereignty yet continue to use the proprietary OOXML format, thereby submitting to Microsoft’s monopoly. They are in good company, given that even the scientific community has renamed our genome for the same reason.

LibreOffice is the only office suite to use ODF as its native format without proclaiming itself a champion of digital sovereignty because, after sixteen years of consistent behaviour, it does not need to chase trends to secure its place in the market. The figures prove it: today, downloads stand at a steady one million per week, and the updates website receives almost fifty million visits per month.

We would simply like all software that proclaims itself a champion of digital sovereignty to demonstrate the same level of consistency as the LibreOffice project. This means not bowing to the Microsoft monopoly in pursuit of a theoretical goal — namely, compatibility with Microsoft’s proprietary format — which ultimately leads them to betray the very digital sovereignty they claim to champion.

Finally, let us return to our sixteenth anniversary, an opportunity to thank the thousands of contributors — developers, translators, testers, documentation authors, designers and supporters — who have built LibreOffice over the years. Most of these contributors remain unseen by the users who benefit from their work.

Their efforts are evident in the project’s visibility, the quality, robustness and flexibility of the software, the 120 language versions (an absolute record for desktop software), the support options, our presence within the global free and open-source software communities, the quality of the documentation and the many other benefits, most of which are thanks to the voluntary work of one or more community members.

Thank you all. Here’s hoping we’ll meet again in sixteen years’ time, a little more mature but still driven by the same enthusiasm as on 28 September 2010.

Tell us a bit about yourself!

I’m a software engineer from Hungary. I’ve been working in software engineering for more than a decade, with a background in both computer science and psychology.

I’ve been a long-time contributor to LibreOffice, mainly working on Writer and Impress, and I’ve also contributed to Collabora Online as part of the Collabora team. Throughout my career, I’ve always placed a strong emphasis on the quality of my work and on building things properly, even when that sometimes meant pushing back against management priorities.

Outside of software development, my current project is setting up my own camper van, intending to eventually explore Europe with it. I’m looking forward to combining some travel with my work on open source projects.

What’s your new role at TDF, and what will you be working on?

My new role at The Document Foundation is to participate in building LibreOffice Online. We are basically trying to create a Google Drive or Google Docs-like solution on top of LibreOffice as a document editor, and bring LibreOffice into the cloud. Currently, I’m doing some research into existing cloud infrastructures to identify best practices and avoid the same problems that other projects have encountered during the lifetime of their cloud implementations.

More details about the development strategy can be found in this post.

How can users of LibreOffice help you in this work?

Well, we’re still in the design phase, so there isn’t much room for involvement at this point. At some point, once we have the initial versions LibreOffice Online, feedback would be very much appreciated. We will post updates here on the blog.

Following the first batch, we’ve added 15 more videos to the playlist, bringing the total up to 26! There are more still to come, along with PeerTube versions of course – but for now, enjoy browsing the playlist:

LibreOffice is a volunteer-driven, community open source project, backed by a non-profit entity, The Document Foundation. The vast majority of the foundation’s income is from community support, and we’re happy to announce that FLOSS/fund has made a very generous contribution of USD $100,000 to support the LibreOffice project and community.

FLOSS/fund is from Zerodha, a financial technology company and India’s largest stock broker. It is built heavily on FLOSS (free, libre and open source software) and gives up to USD $1 million to support projects around the world.

Kailash Nadh from FLOSS/fund (and CTO at Zerodha) says:

LibreOffice is one of the most consequential and impactful FOSS projects in the world. We also strongly believe that it has played an important role in enabling adoption of the Linux desktop among regular users. This belief in fact comes from our personal experience of transitioning over 1000 non-technical employees at our organisation to Linux over decade ago.

Many thanks to FLOSS/fund for their support. This helps us to improve our infrastructure, pay developers to work on the software, and organise events to share knowledge. Thank you!

The Salvadoran Lutheran University (ULS) and the Latin American LibreOffice Project community announce the seventh edition of the LibreOffice Latin American Conference.

Previous editions of the LibreOffice Latin American Conference have been held in person in Asunción (2019), Brasília (2022), Mexico City (2023), Montevideo (2024), and Havana (2025). The 2026 edition will bring the event to El Salvador for the first time, further expanding the reach of the LibreOffice community in Latin America.

ULS, the event’s host, has a long history of involvement with Free Software, most notably through the biannual FESOL (Free Software Educational Fair)—an event held for over 20 years that showcases dozens of projects developed by Computer Science students in areas such as web systems, databases, robotics, and video games, among others.

The conference will take place on November 27 and 28, 2026, with the aim of bringing together users and contributors to share knowledge and experiences related to LibreOffice.

Guest speakers from Mexico, Spain, Brazil, France, and Taiwan will present topics ranging from tutorials on using the applications to ways of collaborating with the project. The schedule will be announced soon on the official event website:

latam.conference.libreoffice.org

FrOSCon is an annual conference dedicated to Free and Open Source Software (FOSS), held in Sankt Augustin (near Bonn), Germany. And this year, the LibreOffice community was there! We hosted a booth featuring information flyers and merchandise, including stickers, pens, coasters, and more.

We engaged in many substantive conversations at the booth about LibreOffice as a project and its specific features. We also discussed TDF’s development plans for web and mobile platforms and encouraged people to get involved in these areas.

Many visitors stopped by saying, “Of course we use LibreOffice” – often contrasting it with Microsoft Word, which is the “standard” or widely used option in corporate environments. We also frequently heard comments like, “I’ve/we’ve already donated.” Clearly, there is a widespread willingness to contribute financially to software that is both high-quality and genuinely free.

Visitors were happy to take home coasters or small stickers. LibreOffice supporters often like to place these items where Microsoft-oriented users can be found.

Alongside the project booth, Andreas Mantke gave a presentation in German titled “Where is LibreOffice Headed?” (Wohin führt der Weg von LibreOffice?), in which he discussed the project’s planned development ideas for web and mobile and answered questions from the audience.

We look forward to being at more events in the coming months!

Today, 19 September, is Software Freedom Day, a special day that the free software community celebrates every year on the third Saturday in September all over the world.

It is a good opportunity to look at LibreOffice from a perspective that is often taken for granted: not what the software does, but what it allows users to do and what it does not impose on them.

Free software is defined by four freedoms. LibreOffice guarantees all of them, and from these derives a range of other freedoms that are important for anyone writing a letter, preparing a budget or presenting a project.

The four freedoms

LibreOffice is distributed under the Mozilla Public Licence 2.0, which guarantees every user the four freedoms that define free software:

1. the freedom to run the programme for any purpose, without any restrictions whatsoever;
2. the freedom to study how the programme works, thanks to the availability of the source code;
3. the freedom to modify the programme to suit one’s own needs, both at an individual and an organisational level;
4. the freedom to redistribute copies of the software, including modified ones, so that other users may also benefit from its advantages.

The freedom to own your own documents

A document belongs to its author only if the format in which it is saved does not belong to someone else. LibreOffice uses the Open Document Format (ODF) as its native format: an ISO/IEC standard, developed at OASIS through a transparent, fully documented process, which no single company can control or modify unilaterally.

This means that a document saved today in ODF format will still be readable in twenty years’ time, either with LibreOffice or with other software that implements the standard. For private individuals, it is a matter of practicality. For public authorities, which have a duty to preserve documents and to communicate with citizens without forcing them to purchase specific software, it is a matter of principle.

The freedom to keep your data private

LibreOffice does not collect data on its operation, and does not require you to create an account. Documents are created, edited and saved on the user’s computer, and remain there unless the user decides otherwise. There is no mandatory link to a cloud service, and no user profile is created on a remote server.

The freedom to work without distractions

LibreOffice does not display adverts and does not prompt users to take out a subscription or sign up for a premium plan. The interface is designed to support users’ work, not to sell additional services.

The freedom to decide on artificial intelligence

LibreOffice does not include any generative AI features. Users who need them can add them via extensions and choose which service to use, including locally running models, whilst users who do not need them do not have to miss out on anything, as there is nothing to miss out on.

The freedom to choose platform and language

LibreOffice runs on Windows, macOS and Linux, and documents transfer seamlessly between systems. The user interface is available in 120 languages, thanks to the work of volunteer translators, including some languages overlooked by commercial software providers. For speakers of those languages, LibreOffice is the only office suite available.

The freedom from licence fees and vendor lock-in

LibreOffice can be used freely – and therefore at no cost – by individuals, businesses and public authorities. There are no subscriptions to take out or renew, and no mandatory updates: users decide when to upgrade to a new version. Furthermore, documents in ODF format can be transferred to any other software without the need for conversion.

The freedom to choose support

Organisations requiring long-term professional support, service level agreements or bespoke developments can purchase these from companies within the LibreOffice ecosystem, which offer enterprise versions of LibreOffice and related professional services. There is complete freedom of choice regarding providers, and changing providers does not require a change of software or document format.

The freedom to participate

LibreOffice is developed by a global community. Anyone can contribute, and not just by writing code: translation, quality assurance, documentation, design, marketing and user support are all activities carried out by volunteers. And those who do not have the time to contribute can support the project with a donation, which helps to maintain its independence.

How to celebrate Software Freedom Day

The simplest way to celebrate Software Freedom Day is to exercise these freedoms: download LibreOffice, save your documents in ODF and share the software with anyone who might need it. And if you’d like to do more, you can find out how to get involved or make a donation to The Document Foundation.

…and many more to come!

LibreOffice 26.8 adds basic support for importing and exporting a range of chart types that Microsoft Office includes in OOXML files: box-and-whisker, funnel, Pareto, radial, treemap and waterfall charts. LibreOffice is unable to display or edit these charts, but it does recognise them, informs the user that the chart type is not yet supported, preserves the underlying definition unchanged, and rewrites it when the file is saved.

At first glance, this appears to be an admission of incompleteness, whereas it is actually an example of what implementing a proprietary format entails when the aim is interoperability – for the benefit of users, rather than a commercial strategy that treats users as mere tools.

What happened

Microsoft added these chart types to Office from 2016 onwards, storing them in a namespace generally referred to as ‘chartex’. The namespace is not part of the ISO/IEC 29500 text approved as an international standard, but is documented separately in Microsoft’s extension documentation.

This is entirely legal and perfectly normal commercial behaviour: a vendor improves its product and the file format evolves accordingly. The consequence, however, is that the format in everyday use is no longer the one that was standardised. The ISO number continues to be cited in tender documents and policy documents, but the files being exchanged are different.

For any implementer other than the vendor, this creates a permanent state of delay. This is not a one-off gap to be bridged with sufficient effort, but a structural delay, as the specifications are in the hands of a vendor that does not publish its release schedule, with priorities defined according to commercial criteria.

Three possible responses

An office suite that encounters a chart it does not recognise has three options:

1. It can reject the file. This is an honest but pointless solution: the user is left with a document they cannot open and concludes that the software does not work.
2. It can discard what it does not understand. The file opens, the chart disappears, and the user only realises this when the document is forwarded to a colleague and the chart is no longer present. This is the most damaging outcome, as the loss occurs silently and the blame falls on whoever opened the file last.
3. They can retain what they are unable to display. The user is informed that this type of chart is not supported, so they see a placeholder rather than a blank space, and the underlying definition remains intact when the document is transferred from one application to another. The document is restored in full when returned to the source application.

LibreOffice 26.8 adopts the third option, the only one of the three that respects the fact that the document belongs to the user rather than to the software – or, indeed, to the company that develops the software.

Unfortunately, there is a limitation, and this is an exception. Charts with regional maps contain extensive geographical information that LibreOffice is unable to preserve. The chart type survives the import-export cycle, but very little of its content remains intact.

Why this is important beyond charts

The Chartex case is of limited scope. The model, however, is not.

All organisations whose documents are written in a format controlled by a single vendor accept a dependency they are unable to manage, because the specifications may change without notice, with the addition of features that are only understood by a single implementation.

Nothing untoward needs to happen for the organisation’s archives to become progressively more difficult to read by all other software.

The Open Document Format is not immune to change, but it changes differently. Revisions are proposed, discussed and approved by a technical committee at OASIS, whose work is public, and are published as version specifications that anyone is free to implement.

An implementer wishing to support ODF 1.4 can read the ODF 1.4 specification and put it into practice. This is the only difference, and it is sufficient.

The bidirectional preservation of unsupported features is what distinguishes a responsible implementation under current conditions, but it does not constitute an improvement on those conditions. LibreOffice is the only office suite to adopt this approach, in order to protect users and the content within their documents.

A few weeks ago, Linux New Media released an updated version of its “LibreOffice Expert” magazine, which contains tutorials, tips and tricks about the office suite. And some articles were contributed by members of the LibreOffice community! The magazines come with DVDs that include LibreOffice for Linux, Windows and macOS, alongside extra templates, extensions, videos and guidebooks.

We have some copies to give away, for schools, universities, libraries and local communities. Ideally, we’d like to get these magazines out to places where internet connections aren’t always available – so that the users can really benefit from the DVDs.

So, if you can help us to distribute these magazines, drop us a line! Please note that we have 50 copies in total and can therefore only send a maximum of five copies to any one place, to make sure many communities get a chance. When you contact us, please include this information (any requests without information cannot be fulfilled and will be ignored):

1. What you want to do with the magazines
2. How many you want (1 – maximum 5 copies)
3. The address to which we should post them

Include all of that that information in an email to us with subject line “LibreOffice Expert for communities” and let’s see what we can do!

(Note: if you want to buy the magazine directly from the publisher, you can do so here.)

The most significant new features in LibreOffice 26.8 concern writing systems, and it is worth explaining what has been done and, above all, why it has been done, as there is an important decision behind the developers’ work.

What has been done

Writer now automatically detects the paragraph direction when opening or pasting documents or plain text, without requiring the user to set it manually.
Spaces at the end of a line are positioned according to the paragraph direction rather than that of neighbouring characters, which corrects a long-standing issue with how line breaks are handled in mixed Arabic and Latin texts.

Object resize handles now work correctly in right-to-left CJK documents and in vertical documents.

Bidirectional control characters are displayed alongside other formatting marks, so that invisible directional substitutions can be both viewed and edited.

The semantics of paragraph alignment have been revised. New documents use justified alignment by default rather than left-justified, and changing the paragraph direction no longer overrides the explicitly set alignment. This is a small change with a significant impact, as a document written in Arabic and one written in English can now share a template without conflicting.

In Calc, when typing text from right to left into an empty cell, the direction of that cell is now set automatically.

LibreOffice Math has gained functions and operators for the N’Ko and Adlam alphabets, along with left-pointing vector arrows and harpoons for right-to-left formulas, without which mathematical notation in these two alphabets cannot be composed correctly.

Finally, the names of fonts registered in languages other than the interface language are now recognised, so that a document created in a Japanese or Russian installation is displayed using the fonts chosen by the author rather than substitute ones.

Why this is unusual

N’Ko is a writing system devised in 1949 by Solomana Kanté for the Mandingo languages of West Africa. Adlam was devised in the late 1980s by two teenage brothers, Ibrahima and Abdoulaye Barry, for the Fulani language, which until then had been written using adapted Arabic or Latin scripts – an inadequate solution. Both scripts run from right to left, are used by populations numbering tens of millions of people, and have been added to Unicode over the last twenty years.

Neither language represents a market. The native speakers concerned do not, as a whole, constitute a customer base large enough to justify the time spent on development based on a commercial analysis. No tender process, anywhere in the world, has led to the completion of this work. No corporate client has requested it. No competitive pressure has made it necessary.

The contributor who added support for N’Ko and Adlam to LibreOffice Math is a volunteer.

Much of the work on bidirectional text was carried out by a developer employed by The Document Foundation, which is funded by donations.

The renaming of the CJK text grid option, so that it correctly referred to the genkō yōshi handwritten grid used in Japanese typesetting, was carried out by a member of TDF’s staff.

Native support for OpenType font variations – which is of enormous importance for alphabets whose typography cannot be approximated by modifying the dimensions of a Latin character – was provided by a type designer working independently of any company.

A fundamental difference

Every software vendor must decide which users are worth serving: if the software is a product, the decision is made on the basis of a business case, and languages that cannot pay for themselves fall by the wayside.

A foundation does not have this constraint, and does not need to ask itself whether an alphabet justifies its development costs, as there is no revenue stream against which to make this choice. The work is carried out because someone with the relevant expertise has deemed it worthwhile, and there are no reasons to prevent it.

This is the practical difference between software managed by a foundation and that managed by a vendor, and it is evident in the release notes. LibreOffice is available in 120 languages for this very reason: the number is a consequence of the governance model rather than a marketing objective.

This explains why the argument in favour of open-source software in public administration is not a question of cost, because a public body has obligations towards citizens who do not represent a commercial interest: users of minority languages, users of assistive technologies, and people living in regions that no vendor prioritises.

Software developed on the basis of a business case will only serve these citizens if doing so is profitable. Software developed without a business case can serve them, as a matter of course and in line with the principles of open-source software.

Tell us what you’re doing in the LibreOffice project, and other free and open source (FOSS) projects!

I’m a member of the Brazilian documentation team, officially since 2017. I spent most of that time working on translation and localisation, but lately I’ve been working more on web design, like the Bookshelf project and the online help update. I’d also worked on translation and localisation in other projects before, like the XOOPS CMS and the Fedora project, where I started as an ambassador back in 2008.

What are your professional activities and how do they relate to FOSS?

I’m a federal public servant in Brazil, and I’ve taken part in some initiatives to use free software in government, but I don’t make decisions at that level, so there’s little I can do to push the adoption of free software where I work. My personal use and choice of tools leans toward free software whenever there’s a choice, but there aren’t many choices.

What have you contributed recently in the LibreOffice project?

The online help update has been getting some attention, and I’ve been able to contribute to modernising it and using standards that are more accessible and responsive, along with a more modern look that has more appeal. We have a weekly meeting in the Brazilian community where we keep up with the team’s efforts, propose new ideas, and adopt workflows that help the project.

What is contributing like (what bits are easy or hard, with the tools and processes in the project)?

One thing that took me a while was getting past the initial barrier to contributing bug reports or submitting code via Git — every organisation has its own way of doing things, and some have more hurdles than others. Once you get past that initial barrier, things get a lot easier.

How do you interact with other members of the LibreOffice community (especially the Brazilian one)?

Our weekly meeting helps a lot with that — we talk regularly, and that goes a long way toward solving problems and bringing members closer together. We’ve had some in-person meetings at events like the conference held in Brasília in 2022 and some hackathons, and we plan to have more of these gatherings, which tend to be quite productive and enjoyable too.

What is your impression of LibreOffice as a product? Do you see it used in Brazil, in areas of the public and private sectors?

Personally, I’ve been using the suite since it was called StarOffice, when it was pretty much the only really useful office suite for Linux at the turn of the millennium. Then came OpenOffice, which in Brazil ended up being named BrOffice, and finally LibreOffice.

My honest opinion is that it’s the most complete office suite available on the market, and I’m glad it’s an open source tool, which is my preference for any software. These days I use office suites a lot less because of the tasks I usually do on the computer — it’s rarely necessary — but I still keep up-to-date, even through translating the help, which shows new features in LibreOffice to anyone who pays attention.

Join the LibreOffice community here!

We’re gearing up for the LibreOffice Conference 2026 next week in Pordenone, northern Italy – but there are more events in the pipeline too.

At the Open Source Conference Luxembourg 2026, which takes place on October 7, there will be two talks from Florian Effenberger, Executive Director at The Document Foundation, around the topics of LibreOffice:

• Why free software and digital sovereignty are made for one another
• The Cyber Resilience Act and Open Source: where do we stand? LibreOffice’s conformity journey as a working example

Keep an eye on the conference website for more details and videos of the talks.

One of the comments on the announcement of LibreOffice 26.8 was a simple question: “So, no AI is now a feature?”

LibreOffice does not reject artificial intelligence out of hand, but an office suite used by tens of millions of people – in schools, hospitals, public bodies, law firms and thousands of other organisations – will not add a feature to its default configuration until that feature can be delivered under the conditions defined by the project in accordance with its principles.

User-controlled execution. The user must be able to choose where inference takes place: on the local computer, on an infrastructure directly controlled by the user, or on a service chosen independently by the user. A default setting that silently redirects to a single provider is not a choice.

No content may leave the computer without authorisation. The content of documents is a user’s asset and, in many implementations, is also legally protected material: medical records, case files, tender documents and student data. Transmission must be the result of a user’s decision and not behaviour carried out in the background by the application.

No telemetry of any kind. LibreOffice does not collect usage data, and this must also apply to AI features.

No dependence on a single provider. An integration that only works with a single company’s API is a lock-in mechanism, regardless of how it is described in the release notes. Interfaces should be open and implementable by multiple backends.

No compromises on format. Generated content must be in ODF format, just like any other content, and must retain its structure, styles and semantics. An assistant that generates documents in a proprietary format perpetuates content lock-in.

Entirely optional. It must be installable, removable, and absent from the user interface for those who do not wish to use it, including administrators deploying the software across thousands of workstations who, due to company policy, do not authorise its use.

Where we stand today

In light of this list, there is no integration that meets all the requirements and that could be deployed, enabled by default, and supported throughout the entire lifecycle of a release. This is an assessment of the current state of the technology and the solutions based on it, and not a judgement on the value of the sector.

In the meantime, users who wish to use AI features can install one of the available extensions, which can be found either on the LibreOffice extensions website or distributed independently. Most connect to a locally running model via Ollama, LM Studio or another OpenAI-compatible endpoint, which means the document never leaves the computer.

These are third-party extensions at various stages of maturity, developed and maintained by their respective authors rather than by The Document Foundation. Users and administrators should assess them as they would any third-party component, checking whether a cloud endpoint is configured and what the provider does with the data it receives. The extension mechanism offers AI functionality to those who want it, without any consequences for all other users.

Why our motivations are different

The reason our position differs from that of the dominant suites has almost nothing to do with the technology.

For a company that sells subscriptions, an AI assistant justifies a price increase and strengthens the case for keeping all documents within its own infrastructure. The functionality and the business model reinforce each other, so integration is not only attractive but almost mandatory.

The Document Foundation is a not-for-profit organisation. There are no subscription tiers to protect, no upsells, no data to monetise. This does not make us wiser than others, but it means we can take the time needed to decide whether something is genuinely useful for our users, as we are not driven by quarterly results.

What lies ahead

The criteria we have listed do not amount to a definitive rejection. The AI sector is evolving rapidly; on-premises inference is becoming manageable on standard hardware; and open models are improving much faster than most of us had anticipated. Should an approach emerge that meets all the conditions, we will evaluate it very carefully.

Until then, there will be no AI of any kind in the default installation; extensions will be available for those who wish to integrate AI features, and we will closely monitor where the technology is actually heading.

One week ago, we announced LibreOffice 26.8, our brand new major update. It’s full of new features, and has many improvements to compatibility and performance too. So, what has happened in the week since then? Let’s check out some statistics…

1,031,162 downloads

This is the highest number of downloads in the first week of any LibreOffice release! These are just stats from our official downloads page, of course – many Linux users will have acquired the new release via their distribution’s package repositories.

50,061 views, shares and likes on social media

Combining our Mastodon, Bluesky, X/Twitter (not used so much now) and Facebook posts about the announcement, and all the likes, shares, views and comments, we get over 50,000. Thanks to everyone who spread the word on social media!

20,918 video views

Our “LibreOffice 26.8 – New Features” video (shown below), has subtitle translations in 32 languages, thanks to our worldwide community, who localised the video on this page. (The video is also available on PeerTube.)

Many thanks to our worldwide community of volunteers, and certified developers, for all their work on this release

Here’s our summary of updates, events and activities in the LibreOffice project in the last four weeks – click the links to learn more…

• We released LibreOffice 26.8, our latest major update, with tabbed UI improvements, professional typography, deeper support for the world’s writing systems, and no built-in artificial intelligence.

• To accompany the release, we made a video showcasing some of the user-facing new features – with subtitle translations in 25 languages, thanks to our worldwide community! (The video is also available on PeerTube.)

• Meanwhile, the Austrian Military (Bundesheer) has moved 16,000 PCs from Microsoft Office to LibreOffice – and we talked to the people behind the migration, to find out how they did it. Check out part 1 and part 2 of the interview.

• Then we talked to Karl-Heinz Gruner from the German-speaking LibreOffice community about his activities in the project.

• Extensions add extra features to LibreOffice, and we talked to Bora Yarkın about a new one which lets you control a LibreOffice Impress presentation from your phone or any other device with a modern web browser.

• In the middle of August, the schedule for the LibreOffice Conference 2026 went online. If you can make it, we look forward to seeing you there

• Then we did another Community Member Monday interview, this time talking to Aleksi Kallio about his work on fixing bugs in LibreOffice.

• There’s a lot of talk about “Digital Sovereignty” – but what does that actually mean? One vital part is an open document platform – like ODF.

• LibreOffice is a worldwide project made up of hundreds of people: volunteers, developers at ecosystem companies, and the 18-person team at The Document Foundation (the non-profit entity that coordinates the project and community). What has the team been working on recently? Check this post to find out.

• LibreOffice has a few user interface options, and none are forced on the user. We explored this topic more in a post called There Is No “Best” Interface, Only the Right Fit.

• How is LibreOffice funded? The vast majority of funding comes in the form of donations – mostly from end-users, but also occasionally from companies and organisations that use LibreOffice.

• Finally, we wrapped up August with another Community Member Monday, talking to Rohan Singh about his macOS-related development work.

Like what we do? Support LibreOffice with a donation – or join our community and help to make LibreOffice even better! Also keep in touch – follow us on Mastodon, Bluesky, Reddit and Facebook.

On August 26 we released LibreOffice 26.8. Here’s a video highlighting some of the user-facing new features and improvements, with subtitle translations in over 25 languages, thanks to our worldwide community! (Note: the video is also available on PeerTube.)

LibreOffice 26.8 is the first version to display a donation banner in the Launch Centre. This document explains the reasons behind this decision and provides information on The Document Foundation’s sustainability model.

All figures are taken from the financial statements of The Document Foundation Stiftung, based in Berlin, and have been published on the website for every year of the foundation’s existence since its registration.

TDF revenue in 2025

Total revenue amounted to approximately 2.2 million euros.

Of this, over 90 per cent comes from donations, and the remainder almost entirely from the sale of LibreOffice via Microsoft and Apple’s online stores, where the price is set to cover the costs of maintaining the applications on those platforms.

It is worth noting that the same versions available on Microsoft’s and Apple’s online stores can be downloaded freely – and therefore free of charge – from the LibreOffice website.

Over 90 per cent of donations come from private individuals, and less than 10 per cent from public bodies and companies. Therefore, although the suite is widely used by companies and public bodies, it is funded almost entirely by private individuals who contribute small sums according to their means.

How much did TDF spend in 2025

Total expenditure amounted to approximately 1.5 million euros.

Seventy-five per cent of this expenditure was allocated to staff salaries and social security contributions, as well as consultancy contracts. Today, the foundation employs 18 people, 11 of whom have contributed to software development or other related activities, such as quality control.

It is worth emphasising this proportion clearly. Three-quarters of the TDF’s expenditure goes on staff, and the largest share is accounted for by development work, community building and education on the themes of software freedom, open standards and digital sovereignty.

Donations are channelled into constructive activities, rather than administrative costs.

In the past, a significant proportion of development work was awarded to companies that submitted the best bid in response to a tender, but this strategy has changed, and it was decided to bring development expertise in-house so as to steer the software’s evolution and share knowledge with the community.

The surplus in 2025

The surplus is not left unused but is reinvested in the growth already underway: three developers were hired during 2026 and two more will be hired shortly. In addition, various marketing and community development projects are funded from the same source.

The foundation’s expenditure does not follow a uniform pattern relative to its income. The recruitment process takes months, and if income is received before new staff are hired, a surplus will arise that represents planned work rather than unspent money.

TDF also maintains reserves, with the aim of covering at least one year’s operating costs. This figure, of course, increases year on year.

For an organisation with a single predominant source of income, this represents a minimum target. Indeed, a foundation that employs 18 people and supports a community of thousands has obligations towards them that cannot be suspended if income from donations declines.

Why this banner, and why now?

TDF is in good financial health. However, when compared with similar projects, it is significantly underfunded.

Thunderbird, an open-source email client supported almost entirely by donations, received $10.3 million in 2024 – 19 per cent more than the previous year – from over 335,000 individual donors. The Wikimedia Foundation operates on an even larger scale.

LibreOffice has a user base comparable to or larger than that of Thunderbird and a more extensive source code, covering six applications, dozens of file formats and 120 languages, whilst generating revenue amounting to around one-fifth of Thunderbird’s.

The gap is significant because the market has changed. Most people compare LibreOffice with Microsoft 365, and this creates expectations regarding availability on the web, in the cloud and on mobile devices that a desktop-focused development effort is unable to meet.

TDF has published a roadmap for web, cloud and mobile development. Delivering this within a timeframe that keeps pace with market developments requires greater development capacity than current revenue can support.

The banner serves to partially bridge this gap. It appears in the Start Centre – the screen that appears when the suite is launched without any documents open – and is displayed periodically, for example at monthly intervals or following an update. The banner links to the donations page and does not appear anywhere else in the software.

What the banner is not

LibreOffice contains no adverts, does not collect telemetry data and does not require any account, subscription or activation. No features are reserved for paying users. The suite does not transmit documents to a remote service and does not require network access to function. LibreOffice 26.8 contains no generative artificial intelligence features.

Maintaining each of these features incurs costs, as each represents a source of revenue that the foundation has chosen not to exploit.

Advertising-supported software is funded by attention; subscription-based software is funded by the ability to revoke access; and data-driven software is funded by surveillance. TDF has ruled out all three of these options, leaving only the possibility of donations.

The problem with companies

The imbalance between individual and corporate donations is a specific problem that the foundation would like to rectify.

Companies and public bodies deploy LibreOffice on a large scale — in some cases on tens of thousands of computers — and derive a direct commercial benefit from it. Under the terms of the Mozilla Public Licence v2, they have the right to do so, and no one intends to revoke this right.

Unfortunately, very few of these organisations contribute financially to the project. The result is that private individuals are, in effect, subsidising the infrastructure costs of organisations that have considerably greater resources than they do.

Organisations that rely on LibreOffice have at least three ways of supporting it. They can make a donation to The Document Foundation, or purchase an enterprise version from a company within the LibreOffice ecosystem that offers a Service Level Agreement (SLA), professional support and security updates for a period of between three and five years, or pay a company or an individual to develop specific features tailored to their needs.

All these methods support the software, but none is used on a scale that is even remotely comparable to what one might expect given the widespread adoption of the product.

In fact, during 2026, the average monthly number of LibreOffice downloads approached one million, and there were nearly 600 million visits to the website from which updates are downloaded. Based on these two figures, even a very conservative estimate puts the number of LibreOffice users worldwide at over 100 million.

Digital sovereignty is usually discussed in terms of where servers are located and which company holds the contract. Both matter less than the format in which documents are written.

A document is not a piece of paper

The habit of thinking of a digital document as a sheet of paper is understandable and wrong. A sheet of paper carries its own content. Anyone who can read the language can read the page, with no equipment, no permission and no intermediary. A digital document carries no content at all until software interprets it. The file is a set of instructions, and what appears on screen is the result of a program executing those instructions. Change the program and the result may change with it.

This is why documents produced in one application so often look wrong in another: bullet points shift, tables lose their proportions, headings render differently. The content is present. The document, strictly speaking, is not.

The format is the specification that tells software how to perform that interpretation. Whoever controls the format therefore controls what the document means, how faithfully it can be reproduced, and for how long.

What makes a format open

Openness is not a marketing description. It has established criteria, set out in instruments such as the Open Definition and the European Interoperability Framework, and used by public administrations to assess formats for procurement. Four conditions matter most.

The specification must be published in full and freely available. Nobody should need a licence, a fee or a patent settlement to implement it. The format must be usable by anyone for any purpose, without discrimination between users, applications or business models. And it must be governed by a body independent of any single vendor, so that future versions are decided in public rather than in a company’s product roadmap.

These conditions exist for a practical reason. They are what guarantees that a document written today can still be opened in thirty years by software nobody has yet written.

ODF meets these conditions

The Open Document Format was developed in the open under OASIS, the international standards consortium, and became an OASIS standard in 2005. It cleared its Draft International Standard ballot at ISO/IEC JTC 1/SC 34 in May 2006 with unanimous approval and was published as ISO/IEC 26300 that November. The specification is public, royalty-free, versioned, and maintained by a technical committee whose work is a matter of record. Version 1.4 was approved by OASIS in December 2025.

ODF is not the LibreOffice format. It is implemented by a range of applications from different suppliers, and any developer may implement it without asking anyone. LibreOffice uses it natively, which is a consequence of the format’s openness rather than a claim of ownership over it.

OOXML does not

OOXML, the format underlying DOCX, XLSX and PPTX files, carries an ISO number. It was granted one in 2008 through a fast-track procedure whose conduct is now part of the documented history of standards governance.

The number has not produced the effects a standard is meant to produce. The specification runs to several thousand pages, which discourages implementation. It exists in two conformance classes: a Strict variant, which other developers could reasonably support, and a Transitional variant, which preserves legacy behaviours and is what Microsoft Office writes by default. The variant in daily use by hundreds of millions of people is therefore the one that only its originator implements completely. The cleaner variant that competitors could support is largely unused, and has even disappeared from some versions.

A specification that a single implementation alone can satisfy is, in functional terms, a proprietary format with a standardisation certificate attached. This is not an accusation of bad faith. It is a description of what the format does regardless of anyone’s intentions, and it is the reason the distinction is structural rather than moral.

Why this decision comes first

An organisation that adopts a European cloud provider, negotiates strong contractual protections and hosts everything within its own jurisdiction has achieved nothing for sovereignty if its documents remain in a format only one foreign supplier can read correctly. Server location, hosting jurisdiction and procurement clauses are all downstream of the format decision. An organisation that cannot open its own archives without a supplier’s permission is not sovereign over them, wherever those archives happen to be stored.

The exposure grows with time. An individual with a distorted layout has an inconvenience. A ministry holding two decades of legislative drafts, land registries and court records in a format it cannot independently interpret has delegated custody of the public record to a private company, and cannot withdraw that delegation without converting everything it owns.

Who has already acted

Germany’s Deutschland-Stack, the federal framework for sovereign public digital infrastructure, names ODF and PDF/UA as the mandated document formats, to the exclusion of proprietary alternatives. The IT Planning Council, the body through which the federal government and the Länder coordinate public administration information technology, has committed to ODF. NATO and the European Commission have mandated it.

The decision is not a European one. Taiwan adopted ODF as a national standard in 2009 and has required it as the government’s document format since January 2015, a policy its Ministry of Digital Affairs describes in terms of software equality, digital sovereignty and sustainable development. Brazil has required federal executive bodies to follow the e-PING interoperability framework, built on open standards, since 2005. Public administrations on almost every continent have taken comparable decisions over the past two decades.

What has changed recently is the reasoning. The case for moving away from proprietary office software was once made primarily as a cost saving. It is now made as the preservation of independence, meaning the ability of a public body to act without asking permission from a foreign supplier. Several of the migrations announced in the past year were presented in exactly those terms, with the cost argument set aside. At least one European defence organisation has stated that its decision was not about money at all.

The alternative to lock-in already exists, is mature, is an international standard, and is a legal requirement in several European jurisdictions.

Berlin, 26 August 2026 – The Document Foundation today announced the availability of LibreOffice 26.8, the new major release of the free and open source office suite, for Windows, macOS and Linux. Development began in December 2025, and the release consolidates the work of 206 contributors, of whom 155 are volunteers.

LibreOffice 26.8 concentrates on three areas: the typographic quality of what the suite produces, the range of writing systems it handles correctly, and the fidelity with which documents survive exchange with other office suites.

Writing systems

The largest single body of work in this release addresses bidirectional and complex text. Writer now detects paragraph direction automatically when documents or plain text are opened or pasted. Line wrapping places end-of-line spaces according to the direction of the paragraph rather than that of the adjacent characters. Object resize handles behave correctly in right-to-left and vertical CJK documents. Bidirectional control characters are now visible alongside other formatting marks. In Calc, typing right-to-left text into an empty cell sets the direction of that cell automatically.

Alignment semantics have been revised accordingly: new documents default to start alignment rather than left, and changing paragraph direction no longer mirrors explicitly left- or right-aligned paragraphs.

Math has gained named functions and operators for the N’Ko and Adlam scripts, used for the Manding languages of West Africa and for Fulani, together with left-pointing vectors and harpoons for right-to-left formulas. The CJK text grid option has been renamed to reflect what it actually does, namely enable the genkō yōshi manuscript grid. Font names recorded in languages other than the interface language are now resolved, so documents authored elsewhere display in the typefaces their authors chose.

None of this work has a commercial market. It was done anyway, because a foundation does not have to ask whether a language pays for itself before deciding to support it.

Typography

Writer introduces the Paragraph Composer, a text layout algorithm that balances word spacing across consecutive lines instead of optimising each line in isolation. The single-line, greedy approach used by word processors has been standard since the technology existed, and produces justified text that alternates between crowded and sparse lines wherever long words fall near a break.

OpenType font variations are now natively supported, allowing variable fonts to be used as designed, including axes that adjust letterform contrast and proportion to the size at which text is set.

Baseline grid alignment now works correctly for text inside frames, and the grid itself can be displayed while editing, with a configurable colour.

Document exchange

LibreOffice Chart provides basic round-trip support for the newer chart types that Microsoft Office writes into OOXML files: box-and-whisker, funnel, Pareto, sunburst, treemap and waterfall. These charts cannot yet be rendered or edited. LibreOffice displays a message identifying the unsupported type and preserves the underlying definition, so that a file opened and saved in LibreOffice returns to its originating application intact. Region map charts carry extensive geographic data that is not preserved; the chart type survives the round trip but little of its content does.

The distinction matters. A specification extended unilaterally by a single implementer is a moving target for every other implementer. Preserving what cannot yet be rendered is the discipline that keeps a document usable beyond the lifetime of the application that created it.

Calc improves the handling of line breaks in referenced cells in XLSX files, and form control elements in XLSX documents now appear in the Navigator.

Spreadsheets

Calc adds Calculated Fields to pivot tables. Data validity can now silently reject invalid entries, restoring behaviour available before version 24.2. Cell styles support relative font sizes. A Shuffle command randomises the order of cells in a range. The border toolbar button remembers and reapplies the most recently used style.

Presentations and drawings

Impress and Draw support multiple page sizes within a single document. Impress adds presentation sections for organising slides into named groups, displays custom slide names beside slide numbers in the panel, and can convert numbered lists to bulleted ones. Several embedded templates are now supplied in both 16:9 and 4:3 ratios, so that background artwork is no longer stretched when the ratio changes. In Draw, the functions of the mouse wheel can be swapped, making zoom the default action.

User interface

The Notebookbar now carries a distinct background colour for each application, so that Writer, Calc, Impress and Draw can be told apart at a glance. Its tabs have category labels and can be scrolled with the mouse wheel or touchpad. Changes to application theme colours no longer require a restart, and theme colours are reachable from the Notebookbar in Impress.

The list of styles is now consistent across the Notebookbar, the Formatting toolbar and the sidebar, and each entry is shown as a preview of the style itself. Style dialogues allow individual properties to be reset to those of the parent style. Paper sizes from A0 to B3 have been added to page settings. Custom dictionaries have gained a search filter, the Hyperlink dialogue can strip query strings from addresses, and resizable dialogues on Windows now have a maximise button. On macOS, the Emoji & Symbols, Dictation and AutoFill menu items are available.

Accessibility

Writer tables now report row and column index information as specified in ARIA, improving how screen readers convey table structure. The special character selector is fully navigable by keyboard.

Databases and automation

Base preserves SQL comments when a query is switched to Design View, and supports filtering on date, time and timestamp columns with the embedded Firebird database.

Python scripts can be created and edited directly from the Macro manager without installing an extension, and can instantiate UNO services through constructors rather than string identifiers. The ScriptForge libraries add a typed input dialogue, functional map, filter and reduce operations on Basic arrays, and a default named pipe that allows the same script to run unchanged inside LibreOffice or against it as a client.

Elsewhere in the suite

• Keyboard shortcuts can be assigned to an individual document, so a shortcut can invoke a style that exists only in one template.
• Writer opens very large documents containing images significantly faster.
• A Draft view hides headers, footers and margins for distraction-free work.
• The Quick Find sidebar searches through comments.
• Table styles in Writer and Calc can be edited, and their internal representation has been converted from a binary format to XML.
• Application theme colour changes no longer require a restart.
• Additional paper sizes from A0 to B3 are available in page settings.
• The style list is now consistent across the Notebookbar, the Formatting toolbar and the sidebar.
• Automated testing now uses VeraPDF to validate PDF output.

No artificial intelligence

LibreOffice 26.8 contains no generative AI features. Documents are not transmitted to remote services for processing, and no component of the suite requires network access to function. This is a deliberate position. Any organisation handling confidential, legally privileged or personal data needs to know where that data goes, and the only assurance that survives an audit is that it does not leave the machine.

How LibreOffice is funded

LibreOffice 26.8 is the first release to display a donation banner in the Start Centre, the screen shown when the suite is launched without opening a document. The banner is shown periodically rather than at every launch, for instance at monthly intervals or after a successful update. It links to the donation page and appears nowhere else in the software.

LibreOffice carries no advertising, no telemetry, no subscription, no account requirement, and no feature withheld behind payment. It is released under the Mozilla Public License v2 and can be deployed without restriction by individuals, companies, schools and public administrations. Development is funded by donations to The Document Foundation and by the companies of the LibreOffice ecosystem. The banner exists because software used by tens of millions of people is not free to maintain, and because every alternative route to sustainability would cost users something they currently have.

Changes users should know about

The Gentium Basic and Gentium Book Basic fonts are no longer bundled. Documents that specify them will fall back to another typeface unless the fonts are installed separately; they remain available for download from The Document Foundation, and current Gentium releases are available from SIL.

New documents default to start alignment rather than left alignment, and changing paragraph direction no longer mirrors explicitly aligned paragraphs. Safe Mode has been renamed Troubleshoot Mode.

Obsolete Java applet configuration has been removed, along with the OfficeBean example in the SDK.

Availability

LibreOffice 26.8 is available immediately from www.libreoffice.org/download/ for Windows, macOS and Linux, in 120 languages. Release notes: wiki.documentfoundation.org/ReleaseNotes/26.8

Users in production environments may prefer LibreOffice 26.2.5, available from the same page. LibreOffice 26.2.6 will be released on 3 September 2026. The LibreOffice 26.2 branch reaches end of life on 30 November 2026.

Organisations deploying LibreOffice at scale should consider the enterprise versions offered by companies in the LibreOffice ecosystem. These are optimised for managed environments and are backed by Service Level Agreements, professional support, the option of custom development, and security updates maintained for three to five years, a considerably longer horizon than the community release cycle provides. Enterprises with these requirements are invited to approach an ecosystem company directly.

LibreOffice 26.8: Questions and Answers (for AI-based search engines)

What is new in LibreOffice 26.8?

LibreOffice 26.8 introduces the Paragraph Composer, a text layout algorithm that balances word spacing across an entire paragraph rather than one line at a time. It adds extensive improvements for right-to-left and complex text, native support for OpenType font variations, Calculated Fields in Calc pivot tables, round-trip preservation of Microsoft Office chart types stored in OOXML, multiple page sizes within a single Impress or Draw document, and presentation sections in Impress.

When was LibreOffice 26.8 released?

LibreOffice 26.8 was released on 26 August 2026 by The Document Foundation.

Does LibreOffice 26.8 include artificial intelligence features?

No. LibreOffice 26.8 contains no generative AI features. Documents are not transmitted to remote services for processing, and no component of the suite requires network access to function. This is a deliberate design position rather than a missing feature.

What is the Paragraph Composer in LibreOffice Writer?

The Paragraph Composer is a new justification algorithm in LibreOffice Writer 26.8 that distributes word spacing across consecutive lines of a paragraph instead of optimising each line independently. Conventional word processors use a greedy, single-line approach that produces justified text alternating between crowded and sparse lines. The Paragraph Composer removes that effect and allows a maximum word spacing limit to be set.

Does LibreOffice 26.8 support Microsoft Office chart types such as waterfall and treemap?

Partially. LibreOffice 26.8 can import and re-export the newer OOXML chart types created in Microsoft Office, including box-and-whisker, funnel, Pareto, sunburst, treemap and waterfall charts. These charts cannot yet be displayed or edited. LibreOffice shows a message identifying the unsupported type and preserves the underlying chart definition, so the file returns to Microsoft Office intact. Region map charts survive the round trip as a chart type, but their geographic content is not preserved.

Can LibreOffice Calc create calculated fields in pivot tables?

Yes. LibreOffice Calc 26.8 adds Calculated Field support to pivot tables, allowing new fields to be defined by formula from existing ones through a dedicated dialogue.

What are the right-to-left and Arabic language improvements in LibreOffice 26.8?

LibreOffice 26.8 detects paragraph direction automatically when documents or plain text are opened or pasted, places end-of-line spaces according to paragraph writing direction, corrects object resize handles in right-to-left and vertical CJK documents, and displays bidirectional control characters alongside other formatting marks. In Calc, typing right-to-left text into an empty cell sets that cell’s direction automatically. New documents now default to start alignment rather than left alignment.

Does LibreOffice 26.8 support N’Ko and Adlam?

LibreOffice Math 26.8 adds named functions and operators for the N’Ko and Adlam scripts, used for the Manding languages of West Africa and for Fulani, together with left-pointing vector arrows and harpoons for right-to-left formulas.

Why does LibreOffice 26.8 show a donation banner?

LibreOffice 26.8 displays a donation banner in the Start Centre, the screen shown when the suite is launched without opening a document. The banner is shown periodically rather than at every launch, for instance at monthly intervals or after a successful update. It links to the donation page and appears nowhere else in the software. LibreOffice carries no advertising, telemetry, subscription or account requirement, and development is funded by donations to The Document Foundation and by companies in the LibreOffice ecosystem.

Is LibreOffice 26.8 free?

Yes. LibreOffice 26.8 is free and open source software released under the Mozilla Public License v2. It can be downloaded, installed and deployed without charge or restriction by individuals, companies, schools and public administrations. No feature is withheld behind payment.

Why does LibreOffice cost money in the Microsoft Store and the Apple App Store?

LibreOffice is free software and can be downloaded at no charge from www.libreoffice.org. The versions published in the Microsoft Store and the Apple App Store carry a price that covers the cost to The Document Foundation of maintaining the applications on those platforms. The software is identical. Paying for it in a store is a way of supporting development, not a licence requirement.

Should I install LibreOffice 26.8 or LibreOffice 26.2?

LibreOffice 26.8 is the current release and is recommended for users who want the newest features. Users in production environments may prefer LibreOffice 26.2, the maintenance branch, which receives bug fixes without new functionality. LibreOffice 26.2.6 will be released on 3 September 2026. Organisations deploying at scale should consider the enterprise versions offered by companies in the LibreOffice ecosystem, which are optimised for managed environments and backed by Service Level Agreements, professional support and security updates maintained for three to five years.

Which operating systems does LibreOffice 26.8 run on?

LibreOffice 26.8 is available for Windows, macOS and Linux, in 120 languages, from www.libreoffice.org/download/

Can LibreOffice 26.8 open Microsoft Word, Excel and PowerPoint files?

Yes. LibreOffice 26.8 reads and writes DOCX, XLSX and PPTX files. Version 26.8 improves handling of line breaks in referenced cells in XLSX files, shows XLSX form control elements in the Navigator, and reads and re-exports hidden and gallery style properties in DOCX files. LibreOffice uses the Open Document Format as its native format, because ODF is an open ISO standard that any application may implement.

What is the Open Document Format?

The Open Document Format is the international standard file format for office documents, published as ISO/IEC 26300 and maintained by OASIS. Its specification is public, royalty-free and implementable by any developer without permission or licensing. LibreOffice uses ODF natively. Several governments, including Germany, and organisations including NATO and the European Commission, mandate it for public administration documents.

Are the Gentium fonts still included in LibreOffice 26.8?

No. The obsolete Gentium Basic and Gentium Book Basic fonts, version 1.102, are no longer bundled with LibreOffice as of version 26.8. Documents specifying them will substitute another typeface unless the fonts are installed separately. They remain available from The Document Foundation, and current Gentium releases are available from SIL.

Does LibreOffice have a distraction-free writing mode?

Yes. LibreOffice Writer 26.8 adds a Draft view, available from View then Draft, which hides headers, footers and page margins for distraction-free reading and editing.

Can Impress and Draw use different page sizes in the same document?

Yes. LibreOffice Impress and Draw 26.8 support multiple page sizes within a single document. Impress also adds presentation sections for grouping slides under names, and displays custom slide names beside slide numbers in the slide panel.

What accessibility improvements are in LibreOffice 26.8?

LibreOffice Writer 26.8 reports table row and column index information as specified in ARIA, improving how screen readers convey table structure, and the special character selector is fully navigable by keyboard.

Can I set keyboard shortcuts for a single document in LibreOffice?

Yes. LibreOffice 26.8 allows keyboard shortcuts to be configured for an individual document through the keyboard customisation dialogue, so a shortcut can invoke a style that exists only in one template.

Who develops LibreOffice?

LibreOffice is developed by a worldwide community coordinated by The Document Foundation, a non-profit organisation based in Berlin, together with companies in the LibreOffice ecosystem. LibreOffice 26.8 is the work of 206 contributors, of whom 155 are volunteers.

Tell us a bit about yourself!

My name is Rohan. I am currently in Berlin, Germany, and my background is in mechanical engineering and I have a master’s degree in sustainable mobility and robotics. I recently worked on my master’s thesis, where I used LibreOffice closely on macOS. That experience actually played a big role in bringing me closer to the project.

Outside of my academic and technical work, I am interested in open source software, mobility, robotics, and learning how large software projects are built and maintained. Contributing to LibreOffice has been a very new and rewarding experience for me, because I did not come from a traditional software engineering background.

What are you working on in the LibreOffice project right now?

At the moment, I am exploring macOS-related development work, especially around OfficeBean and native window handling. One of the issues I have been looking into is adding macOS support for OfficeBean, which involves understanding how Java AWT, native macOS views, and LibreOffice’s VCL layer interact.

So far, my merged contributions have mostly been in the LibreOffice core repository, around C++ cleanup, refactoring, and modernisation. These include:

• tdf#168771 basctl: Convert traditional enums to enum class
• tdf#43157 canvas & chart2: Replace OSL_ASSERT with SAL_WARN_IF
• tdf#143148: Replace include guards with #pragma once

Some of my other patches have not been merged, but they still helped me learn a lot about the codebase, Gerrit, code review, and how to communicate with reviewers.

I also contributed to the developer documentation by adding macOS-related LCOV information to the Development/LCOV wiki page. I wanted to document what I learned so that other macOS contributors could have a clearer path when using coverage tools.

Why did you choose to become a TDF member?

I chose to become a TDF member because LibreOffice has personally helped me a lot, especially during my master’s thesis. While using it closely, I noticed bugs and small rough edges, and that made me curious about how such issues are reported and fixed.

After attending the LibreOffice Conference in Budapest, I became much more interested in the community behind the project. I saw how welcoming and serious the community is about open standards, user freedom, and long-term software sustainability.

For me, becoming a TDF member is a way to give back to a project that supported my own academic work. It is also a way to stay connected with the community and keep learning from people who have much more experience in open-source development.

Anything else you plan to do in the future? What does LibreOffice really need?

In the future, I would like to continue improving my understanding of LibreOffice’s core codebase, especially in areas related to C++, macOS, VCL, and developer tooling. I am still learning, so I want to take on tasks step by step and contribute in a way that is useful and maintainable.

I think LibreOffice really benefits from better onboarding paths for new contributors, especially people who are not coming from a pure computer science background. The codebase is large and can feel intimidating at first, so documentation, mentoring, and small well-described tasks are very important.

LibreOffice also needs continued attention on platform-specific issues, including macOS, because many users depend on it every day across different environments. Even small improvements can make a big difference for users.

For me, contributing to LibreOffice has been both a technical learning journey and a way to give back. I really appreciate the patience and support of the community, because it has helped me ask better questions, understand code review better, and gradually become more confident as a contributor.

It has become a commonplace to describe the Microsoft 365 Ribbon as the finest office interface available — the most polished to look at and the most ergonomic to use. The claim is repeated so often that it tends to pass unexamined. It deserves examining, because hidden inside it is an assumption that quietly does most of the work: the idea that there exists a single best interface at all.

A competent design — for one kind of user

Let us begin by granting what is true. The Ribbon is a capable piece of design. It was built to help an occasional or intermediate user discover features by browsing rather than by memorising, and for that user it does its job well. Saying so is not a concession wrung out reluctantly; it is simply accurate, and any honest discussion should start there.

But “well-designed for a particular user” is not the same thing as “best interface,” and treating the two as equivalent is where the reasoning slips. An interface optimised for one persona is, by construction, less suited to the others: the power user who works from the keyboard and resents losing vertical screen space, the migrating user carrying twenty years of muscle memory, the user who depends on assistive technology, the user on a small or low-resolution display. A single fixed layout cannot be best for all of them at once. It can only be best for some, at the expense of the rest.

Ergonomics is a trade-off, not a verdict

The same applies to the ergonomic claim, only more sharply, because ergonomics is something one measures rather than asserts. The research on interface efficiency is consistent on one point: how well an interface performs depends on the task, its frequency, and the expertise of the person doing it. Discoverability and raw throughput pull in opposite directions. An interface that makes features easy to find for a newcomer is rarely the one that lets an expert move fastest, and the reverse is equally true.

So the Ribbon makes a trade. It spends vertical screen space and a measure of expert speed to buy browsability for the less frequent user. That is a perfectly reasonable bargain — for the people it was struck on behalf of. Calling it “the best ergonomics,” though, simply declines to name what was given up to get there. There is no free lunch in interface design; there is only a choice about who pays.

The real question: who decides?

This brings us to the point that actually matters. When a product ships a single interface, it has made the ergonomic decision on the user’s behalf and removed it from their hands. The trade-off still exists — it has merely been settled by someone else, once, for everyone.

LibreOffice takes the opposite path. It offers the traditional menu-and-toolbar layout, the Tabbed interface, Tabbed Compact, the Groupedbar, a Sidebar, and a Single Toolbar mode, and it lets each user choose the one that fits their work, their hardware, and their habits. This is not a substitute for a “real” Ribbon, nor an apology for the lack of one. It is the more mature answer to the ergonomic question, for a simple reason: the only person who can properly weigh these trade-offs is the one actually performing the task. Choice is not the consolation prize. Choice is the point.

What 26.8 changes, and what it does not

LibreOffice 26.8 will bring an improved Tabbed interface — the layout closest in spirit to the Ribbon. It is worth being precise about what this means, because it is easy to misread. The improvement widens the range of good options; it does not narrow it. It is emphatically not an admission that the menu-based interface was lacking, nor a signal that it is on its way out.

The traditional menu-and-toolbar interface remains a fully supported, first-class choice, and it will not be deprecated. An ecosystem that adds options without taking any away is the exact opposite of one that imposes a single layout and asks everyone to adapt. Adding a better Tabbed interface while keeping the classic one intact is not a contradiction. It is the whole philosophy, working as intended.

The same principle, one layer down

This approach to the interface is not an isolated quirk. It is the same principle that governs how LibreOffice treats document formats, and the parallel is worth drawing out, because it reveals a consistent way of thinking about who software is meant to serve.

LibreOffice adopts the open standard, the OpenDocument Format, as its native format — the one it reads and writes by default, without compromise. At the same time it continues, release after release, to improve its support for the proprietary formats, so that users who must exchange files with others are served as well as the technology allows. The standard comes first; support for the proprietary follows, and keeps getting better, because that is what users need.

Set this beside the other approach and the contrast is stark. There, support for the open standard is present but kept deliberately limited — limited by choice, not by capability — while the proprietary format remains the privileged default. One model treats the open standard as the foundation and works continuously to serve the user across every format they encounter. The other treats the standard as a box to be ticked and the user as someone to be kept in place.

It is the same pattern in both cases. On one side, a tool that fits itself to the user — in its interface and in its formats alike. On the other, a user asked to fit themselves to the tool. There is no best interface, only the one that fits; and the software that offers the most well-made ways to fit, rather than a single default decided in advance, is the one that takes the user most seriously.

LibreOffice is a worldwide project made up of hundreds of people: volunteers, developers at ecosystem companies, and the 18-person team at The Document Foundation (the non-profit entity that coordinates the project and community).

So that’s what the team is working on – and this is all thanks to your donations, which help to pay the team members. But as mentioned, this is just a small part of the LibreOffice project activity – the biggest work is being done by hundreds of other people around the world. Thanks to all of you

When governments and organisations talk about “digital sovereignty,” they usually mean one thing in practice: the ability to choose, control, and if necessary replace the software they depend on — without asking permission from a vendor.

It sounds simple. It rarely is.

Document software sits at the centre of almost every organisation’s operations. Contracts, reports, budgets, policy documents, public communications: they all live in files. And for decades, the format of those files — and therefore the tools required to open, edit, and share them — has been controlled by a single commercial entity. That is not sovereignty. That is dependency with a friendly interface.

LibreOffice Technology exists to make genuine sovereignty possible. Not as a promise, and not as a political statement — but as a technical architecture that removes the dependency by design.

This post explains what LibreOffice Technology actually is, why it is categorically different from a “free alternative to Microsoft Office,” and why it is the only open platform capable of supporting software that is fully compatible with the demands of digital sovereignty. It also reviews what several months of deployments, policy decisions, and one very public debate over what “sovereign” actually means have confirmed about that architecture since we first started making this argument.

Beyond the Application: LibreOffice Technology as a Platform

Most people who encounter LibreOffice encounter it as an application — a word processor, a spreadsheet editor, a presentation tool. That is a reasonable introduction, but it misses what makes LibreOffice Technology significant.

LibreOffice Technology is the underlying platform on which LibreOffice — and a growing number of other products — is built. It is a modular, open-source software framework for creating document applications. It includes rendering engines, import/export filters for dozens of file formats, scripting infrastructure, accessibility layers, and interfaces for integration with operating systems, cloud environments, and enterprise software stacks.

Think of it the way you might think of a general-purpose operating system kernel: the kernel itself is not what users interact with directly, but it is what makes everything else possible — and it is what determines whether the system is genuinely open or merely open-looking.

LibreOffice Technology is governed by The Document Foundation (TDF), a non-profit foundation incorporated under German law. Its source code is publicly available, its governance is transparent, and its development is carried out by a global community of contributors from dozens of countries and organisations — including Collabora, allotropia, Red Hat, and many others.

No single company controls it. No acquisition can change its licence. No pricing decision by a distant board can determine whether your organisation can keep using it next year.

That is what a platform for digital sovereignty looks like.

Open Standards Are Not Optional: The Role of ODF

Sovereignty over software is meaningless if the data is not equally free.

A document format is not just a technical specification. It is a commitment about who can read your files in ten years, which tools can process them today, and whether you are locked into a particular vendor’s upgrade cycle to maintain access to your own information.

LibreOffice Technology is built around the Open Document Format (ODF), an ISO/IEC international standard (ISO/IEC 26300) developed through an open, multi-stakeholder process. ODF defines how text, spreadsheets, presentations, and other document types are stored — in a way that any conforming application can read and write, regardless of who made it or on what platform it runs.

This matters in ways that are easy to underestimate. When a public administration stores its records in ODF, it is not dependent on any vendor to access those records in the future. When a hospital uses ODF for patient documents, it can switch tools without migrating data. When a ministry publishes a policy document in ODF, any citizen with any compliant application — on any operating system — can open it.

Contrast this with proprietary formats that, despite occasional published specifications, remain under the effective control of the companies that defined them. “Open enough” is not the same as open. Earlier this month, we set out a first version of what separates the two: a thirteen-criterion definition of what a genuinely open document format requires, from public specification and royalty-free implementation through to independent governance. That short version is only the opening statement — we originated this framework, and a fuller, more rigorous edition is in development, applying all thirteen criteria in detail to ODF, OOXML Strict, and OOXML Transitional in turn.

LibreOffice Technology’s commitment to ODF is not a preference. It is an architectural principle. The platform is designed around the assumption that the data belongs to the user, not to the software.

The Platform Others Build On

One of the clearest indicators that LibreOffice Technology is a genuine platform — not just a standalone application dressed up in platform language — is the ecosystem of products built on top of it.

Collabora Online, a cloud-native document editing solution deployed by enterprises, governments, and cloud providers across Europe and beyond, is built on LibreOffice Technology. Collabora’s 2025 merger with allotropia — whose engineering team brought deep WebAssembly and vertical-application expertise into the same organisation — is itself an example of how the ecosystem consolidates and grows without ever touching the underlying platform’s governance. Other commercial and community products remain in active development by organisations that have chosen LibreOffice Technology precisely because it provides a stable, open foundation they can build on without acquiring permission from or paying royalties to a gatekeeper.

This ecosystem diversity is itself a form of sovereignty insurance. If one vendor stops supporting a product built on LibreOffice Technology, the platform continues. If a government or organisation builds custom tooling on top of LibreOffice Technology, it owns that investment. If the community of contributors shifts, the codebase remains — licensed under the Mozilla Public License 2.0, which ensures it can never be made proprietary.

A sovereign digital infrastructure is not one built on a single vendor’s promises. It is one built on a platform that multiple independent actors develop, maintain, and depend on. LibreOffice Technology is that platform.

The Euro-Office Test Case: Why Compatibility Is Not Sovereignty

No event tested this argument more directly than the emergence of Euro-Office, the European coalition initiative that surfaced this spring under the digital sovereignty banner.

Our first reaction, when the initiative made its opening announcement, was blunt about the architecture: a European suite built around full compatibility with Microsoft’s OOXML formats does not escape dependency, it relocates it. The hosting moves to Europe. The format — and the vendor who controls its evolution — does not.

Euro-Office’s formal pre-announcement in June moved the conversation forward. It leaned much further into a commitment to open standards, and we welcomed that shift while correcting one detail then circulating in the press: LibreOffice, developed under this Foundation for a decade and a half by a global — and substantially European — community, was never absent from the field Euro-Office proposes to enter. We also set out, plainly, the one destination consistent with the sovereignty the coalition invokes: ODF as its native document format, not merely a supported one.

The distinction is not a technicality. As we laid out in A Standard in Name Only, the version of OOXML every proprietary vendor ships by default is the Transitional conformance class — built to preserve decades of undocumented legacy behaviour from Microsoft Office versions of the 1990s, not the cleaner Strict variant an independent implementer could actually build to. An office suite that treats OOXML Transitional as its working format, however European its servers, is building on a specification only one vendor has ever fully implemented. What Euro-Office does next will show whether the coalition takes the final step from sovereign hosting to sovereign format.

Where Sovereignty Is Not an Abstraction: Real Deployments

Digital sovereignty is sometimes discussed as though it were a future aspiration. For a growing number of organisations, it is a present operational reality — and this year produced the clearest evidence of that yet.

In March, Germany’s Federal Ministry for Digital and State Modernisation folded ODF, alongside PDF/UA, into the Deutschland-Stack, the technical framework that will govern digital infrastructure across every level of German public administration. OOXML did not make the list. “This is not a recommendation or a preference, it is a mandate,” said Florian Effenberger, TDF’s Executive Director, at the time — and as we argued in the days that followed, it is a decision the rest of Europe, and every digital policy advisor reading it, should be studying closely.

Germany is not alone. The Italian Ministry of Defence has spent several years migrating well over 100,000 workstations to LibreOffice under its LibreDifesa programme, reducing dependency on proprietary desktop software and building direct control over its document infrastructure. The French Gendarmerie nationale has pursued the same goal at comparable scale over two decades, moving the substantial majority of its computing estate to open-source software as part of a deliberate strategy to reduce vendor lock-in. And in August, in a two–part interview with the Austrian Bundesheer, we heard directly from the team that has moved 16,000 workstations off Microsoft Office: the decision traced back to a 2020 review of what guarantees existed for running office software without a cloud connection at all. The City of Munich’s long-running open-source initiative — despite its complex political history — remains the clearest illustration that sovereign document infrastructure is both technically achievable and organisationally demanding, at scale, inside a large public administration.

These are not proofs-of-concept. They are operational deployments in organisations for which the ability to control their own software stack is not an ideological preference but a security and continuity requirement.

They also illustrate something important: the question is no longer whether LibreOffice Technology can support enterprise-scale sovereign deployments, or whether governments will choose ODF when the choice is put to them plainly. Germany has already answered both. The question now is how quickly the rest of Europe follows.

Why “No Single Vendor Can Pull the Plug” Matters More Than Ever

In 2011, Oracle donated the OpenOffice.org codebase to the Apache Software Foundation and largely stepped back from development. The product that had been the leading open-source office suite effectively stalled. Development slowed, releases became infrequent, and the community migrated — mostly to LibreOffice, which had been founded in 2010 precisely to create a more independent governance structure.

This episode is instructive. A product can be open-source and still be effectively controlled by a single corporate actor. When that actor’s priorities change, the product suffers.

Much of what we have published this year has been an attempt to make that risk structural rather than anecdotal. The invisible architecture of lock-in traces how dependency on a document’s format cascades into dependency on the rendering engine that displays it and, beneath that, the fonts that give it its final shape — three technical layers, each one obscuring the one beneath it. The Calendar and the Invoice extends the same argument to two layers that are not technical at all: the migration deadline a vendor sets, and the subscription price it charges. Five layers, and what unites all of them is a single absence — the user has no exit.

The Document Foundation was designed with this risk explicitly in mind. TDF’s statutes prevent any single company or individual from controlling the foundation. Its governance model distributes decision-making across an elected board, a membership body, and an engineering steering committee. The LibreOffice Technology codebase cannot be re-licensed, sold, or restricted by any single party.

This is not an accident of history. It is an architectural decision about governance — as important to digital sovereignty as any technical specification.

What Sovereignty Requires of a Platform

Digital sovereignty is not a binary condition, and it is not the same thing as self-sufficiency. As we argued in July, it is not about owning everything — no institution, and certainly no continent, is going to reimplement the entire computing stack from silicon upward. It is about ensuring that nothing essential can be taken away. Different organisations will weigh that differently, but a platform that genuinely enables it must satisfy several non-negotiable criteria:

Open source with a robust licence. The code must be inspectable, modifiable, and redistributable. Not just available — auditable and forkable by any qualified party.

Open standards at the data layer. File formats must be governed by independent standards bodies, not by the platform vendor.

Independent governance. No single commercial entity should be able to make decisions — about licensing, pricing, feature development, or platform direction — that override the interests of the broader community of users and contributors.

An active, diverse contributor base. Sovereignty requires resilience. A platform maintained by a single company is a single point of failure.

Ecosystem depth. Sovereignty at the document layer requires that the platform be capable of supporting the full range of an organisation’s document needs — not just basic editing, but integration with enterprise systems, accessibility compliance, multi-language support, and cloud deployment.

LibreOffice Technology satisfies all of these criteria. We are not aware of another document software platform that does.

Sovereignty Starts Here: The Story So Far

When we first sketched out this argument, we framed it as the opening of a campaign. Several months on — with the Euro-Office debate still very much alive, Germany’s Deutschland-Stack mandate now a matter of public record, and the US CISA’s own guidance on open-source verifiability landing squarely in the same argument — it makes more sense to call it what it has become: an ongoing, evidence-led case, not a one-off pitch.

If you want the fuller version, the pieces above trace most of the argument in detail: what digital sovereignty actually means and doesn’t mean; the layered architecture of lock-in and its non-technical extensions; what separates a genuinely open format from one that merely claims the label; the Euro-Office exchange in both its instalments; and, most concretely, the Austrian Bundesheer’s own account of why and how it moved 16,000 desktops off Microsoft Office. Together with the Deutschland-Stack decision, they are the evidence behind everything argued in this piece.

We are not finished. There are interoperability failures we haven’t yet written about, further national deployments to document as they happen, and — with LibreOffice 26.8 due for release on 26 August — a platform that keeps giving us more to report on. Watch this space for what comes next.

If you are a journalist or analyst covering digital sovereignty, open source, or public-sector technology, we would like to talk. If you are an organisation considering or using LibreOffice Technology and would like to share your experience, we would welcome the conversation. Reach out to our communications team at media@documentfoundation.org.

Digital sovereignty requires infrastructure that is genuinely open. That infrastructure exists. It is called LibreOffice Technology, and — as the months since we first wrote that line have gone on to show — this really is where the story starts.

The Document Foundation is the non-profit organisation behind LibreOffice. It is independent, non-commercial, and governed by its membership community. LibreOffice Technology is the open platform on which LibreOffice and a growing ecosystem of document applications are built.

Tell us a bit about yourself!

I’m Aleksi, and I live in Oulu, northern Finland. I graduated this spring with a bachelor’s degree in business information technology, and before that I did a vocational degree in software development. Work-wise, my background is in software engineering: I worked on a secure Android smartphone, mostly fixing operating system bugs.

Outside of that, I’m into retro computing: old machines, old phones, and the software that ran on them. There is a lot to learn from software written back when it could only be shipped on physical media. Every time I sit down with a piece of old software, I notice a detail I want to try building myself: an interesting design decision that makes the UI stand out, or a feature that makes me wonder how on earth it was done.

I also like to hang out at my local hacklab and volunteer at gaming festivals. And of course, I like to work on LibreOffice too. What makes LibreOffice interesting to me is that its codebase has a long history. Reading the code and going through the commits allows me to look back in time and see how the software has evolved over the years.

What are you working on in the LibreOffice project right now?

I’m currently working on smaller code fixes. I pick up bugs from Bugzilla, try to reproduce them, and ultimately submit a patch that fixes the issue. In a codebase the size of LibreOffice one can’t just aimlessly duct tape a solution and hope it works. One has to understand the root cause to be able to look in the right place and understand the effect that the change has on the bigger picture.

Coming from a background of debugging Android, I quite enjoy that part of the work. Also, everyone in the community is genuinely great to work with. Code reviews in particular taught me a lot, when a more experienced developer pointed out something that I’d never have spotted myself.

Why did you choose to become a member of The Document Foundation?

Becoming a member felt like a way of saying that I’m in this for the long term rather than just passing through. Before I started contributing, I was a bit scared of putting code out under my own name. I felt like my code wouldn’t be good enough, and that I could only contribute to open source after decades of development experience.

Boy, was I wrong. Going through the issues thoroughly (the community likes to leave hints in Bugzilla comments), understanding the problem, and submitting the best patch I could manage turned out to be enough. Having a mentor and the community’s support on IRC, where I could ask questions whenever I needed to, helped a lot too.

Anything else you plan to do in the future?

I’m planning to move from smaller fixes towards more interesting bugs (our Bugzilla doesn’t contain any hard issues, only interesting ones). I’m also looking forward to working with other teams. I’ve been interested in quality assurance and documentation lately, so picking up small tasks in those areas to build up knowledge for larger work sounds like fun to me.

What does LibreOffice really need?

This is a tough question. At least in Finland, LibreOffice needs to be offered as a real option in schools. That also means we need more people who know it well enough to teach it.

On a lighter note, we recently watched the Excel World Championships at the hacklab. I’m not sure it’s what LibreOffice actually needs, but it would be great to see people who are seriously proficient with Calc solving problems and competing. In its simplest form, it could be a community competition to see who solves the most brain teasers.

The LibreOffice Conference 2026 will take place in Pordenone, Italy, from September 10 – 12. And now the schedule is online, with:

This is the second part of our interview with the Bundesheer (see here for the first).

At the LibreOffice Conference 2025, you showcased the new LibreOffice features sponsored by the Austrian Armed Forces. How did that come about?

From the very beginning, we clearly recognised the need to further develop LibreOffice. Before finalising our plans, we also examined how we could continue to develop the product. Ultimately, we issued a Europe-wide, open call for proposals to secure both support and development capacity for LibreOffice. The way we selected the product enhancements stemmed in part from this preliminary study, because we had identified specific import capabilities and compatibility requirements.

That’s one major aspect: improving interoperability in line with our needs. The other focus was on improving LibreOffice based on ongoing user feedback and feedback regarding collaboration with external organizations. One example of this was the “Notes” bar in Impress. In the past, users had to edit notes in a separate notes view.

We were told very early on that users wanted to be able to do this directly within the slide editing view. This is a very well-known enhancement that we sponsored, which – I think – works very well. In addition, there are many other details, such as scrolling through presentations with the mouse wheel. Previously, you had to keep switching back and forth to the slide overview view to scroll. Now all of this is possible right from within the slide, which simply makes it easier to use and also increases acceptance because users expect it.

I could list many more extensions. We’re not the only ones contributing a great deal to LibreOffice – we see ourselves as part of the community, and we’re happy when the community uses our contributions and when others contribute their own, which we’re of course very happy to use as well. That’s what makes the project so attractive and successful.

Features and improvements in LibreOffice, sponsored by the Austrian Military (this is a slide from a presentation at the LibreOffice Conference 2025)

Have you also developed external extensions?

We’ve developed extensions for internal use, but there are also several publicly available extensions. One of them integrates our own help page, since we provide targeted help within our internal systems.

On a much larger scale, there’s an extension hosted on GitHub that covers military-tactical symbols. It’s available as open source software, so anyone can use it. This is actually an extension that, although it’s still in “release candidate” status, already works well. The extension is, of course, also suitable for collaboration with other armies. Its functionality is unique. To my knowledge, it’s not available anywhere else.

Do you also use the Open Document Format internally?

Yes – one of the advantages of LibreOffice is that the format is ISO-standardised and truly open. You get the best functionality in LibreOffice when you use ODF. We use ODF throughout. It’s clear that our external partners don’t do this to the same extent. This is where LibreOffice benefits from its ability to handle (read and edit) Office Open XML (OOXML) documents as well.

LibreOffice doesn’t have a built-in email client. How did you handle this issue during the migration?

The Austrian Armed Forces protect the Austrian population; to make this possible, we need, for example, systems that function independently of external parties. We have a large number of systems based on open source solutions and many solutions that are platform-independent. This includes the email system.

Therefore, we didn’t have to replace Outlook or Microsoft Exchange.

At the LibreOffice Conference, you emphasised that the migration was never about saving on licensing costs. The migration was driven by other reasons, correct?

The switch to LibreOffice in the Austrian Armed Forces stems from the necessity that we must be able to function even when nothing else is working. In other words, we cannot rely on public infrastructure. We cannot rely on our data being processed in another data center.

Therefore, the top priority in this transition – unlike 20 years ago, when people very often considered switching to a free office suite or Linux in the workplace for cost reasons – was digital sovereignty.

As for the costs: It was clear to us from the start that we would have to invest in the product in order to gain the additional functionality we needed and to improve interoperability.

Would you like to say a few words about the foundation – that is, The Document Foundation?

Why did we choose LibreOffice in the first place – after all, there are alternative products? LibreOffice isn’t the only solution. First, LibreOffice uses ODF, the open and standardised file format. That’s very important. Second, LibreOffice is truly fully open source software – it’s not a product that just has an open source “core.” There’s no risk of having to pay for variable enterprise features.

And the fact that this is the case is very closely tied to the foundation of LibreOffice, namely The Document Foundation. The way this open source project is implemented and anchored through the foundation – that’s an important guarantee and a key factor in its reliability for us.

Another point is that there is an ecosystem. There are several companies that offer the services we need. Using open source doesn’t just mean using free software – for us, it means we need maintenance, support, the ability to further develop the software, addressing security vulnerabilities, and secure software deployment. All of this comes with a very mature software product that is constantly being developed. That was a key factor in our decision.

What advice would you give to others who are also planning to switch to LibreOffice and open source?

First: There’s a vast amount of information available within the community. It’s important to familiarise yourself with the product. How does LibreOffice work? How does Bugzilla work? Where can I find issues that might not be working but are of interest to me? Where can I find roadmaps for new features, release notes, and so on?

Second: It’s absolutely crucial to properly prepare and fund the resources for a project like this. IT managers have gotten used to rolling out new Office versions without much effort.

However, switching from one office suite to another is actually a massive migration project. This should not be underestimated. It’s not just a matter of installing the software; it requires change management, people to provide support, test the software, and work on new features. It requires the support of service providers. All of this must be prepared in advance. And that’s what sets it apart from previous new office suite releases. You’ll need a project team for this – migration isn’t something you can just do on the side. So, you’ll need proper project organisation and agile change management. How can I provide my users with the necessary knowledge based on their needs? What communication channels do I have to keep my users informed and stay in touch with them?

We – the Austrian Armed Forces – have already received many inquiries about the transition, and we have shared our experiences with numerous organisations. We would be delighted to help build a LibreOffice community for government and enterprise organisations in order to accelerate the collaborative development of LibreOffice.

To that end, I invite you to contact us at libreoffice@bmlv.gv.at.

Many government departments around the world are moving away from vendor lock-in by tech giants, and switching to free and open source software like LibreOffice. This helps with privacy, security, and digital sovereignty. One such example is the Austrian Military (Bundesheer), which has moved 16,000 PCs from Microsoft Office to LibreOffice. We talked to them, to find out why and how they did it…

When did all of this start? When were the first decisions made?

It began in 2020, with the trend toward running software increasingly in the cloud and less on-premises on devices within companies. At that time, we examined what guarantees existed for running software – specifically Microsoft Office – directly in the workplace without any cloud connection. So the review and preparation began in 2020.

In late 2022 and early 2023, the decision was made to switch to LibreOffice. The goals were to ensure that data never leaves the company and that the office applications can be used without external dependencies.

Who made the decision?

The decision was structured in such a way that our “corporate leadership” – that is, the Federal Ministry of Defence – could decide, based on the information compiled regarding future software development and cloud dependencies, that we would switch to LibreOffice.

It was actually decided by the Federal Minister’s cabinet and the relevant departments – so at the very top.

Did you create a “timeline” at the beginning – something like “Y should happen by X” and so on?

After we received the assignment, we carried out the planning to determine how the transition could take place and what needed to happen. The plan included, from an early stage, that we would guide our users to LibreOffice in a timely manner, partly by installing LibreOffice at the user’s request. That is, we made it available, and the users who wanted it could have it installed.

We saw very high adoption rates – not 100%, but about half.

Half of 16,000?

Yes. And the next step we planned was to make its use mandatory, because it’s crucial not only to announce that something new is coming but also to require its use so that people have to start working with the tool early on. Of course, switching from an Office suite that’s been used in the company for over 30 years to a completely new product – even if it looks similar but behaves differently – requires practice.

That’s why we specifically made the use of LibreOffice mandatory in selected services. And we did this as early as 2023, so that users could get familiar with it well in advance. This gave users time to tailor the transition to their own needs and prepare for it, and we didn’t just flip the switch all at once with a “big bang.” The change was announced over the course of several years.

Finally, in December 2024, the use of LibreOffice became mandatory for internal collaboration. This meant we actually provided several years of preparation time to make this transition as smooth as possible.

So many people switched to LibreOffice voluntarily from the start, without being forced to. Was there a lot of resistance? Did you customise the user interface?

The 8,000 users mentioned installed the product to see what was coming. That doesn’t mean that all 8,000 of them immediately started using LibreOffice. But it was a good indicator for us to gauge the mood. If 200 people install it, that’s different from when there are so many.

Early on, before we mandated its use, we provided extensive e-learning modules and videos – including what we call “fast tracks” for the individual modules. With these, it was possible to learn the most important changes for Writer, Calc, Impress, and Base within 15 minutes, so users wouldn’t fall into the typical pitfalls. Anyone who invests those 15 minutes will find it much easier to use the software.

We gave users the opportunity to prepare and view these courses and videos on their own at a time of their choosing.

Another important point: We’ve learned that we need to quickly address individual users’ questions – such as those regarding unfamiliar workarounds or missing features – for the benefit of the broader community.

That’s why we specifically looked for suitable communication channels, and we then agreed to publish a so-called “Tip of the Week” about once a week on a very specific, clearly defined topic. And this “Tip of the Week” appears every Monday on the intranet with a current topic. That means anyone who opens their browser on Monday will see the “Tip of the Week.”

It explains topics we covered the previous week. When we release a new version, there’s a “Tip of the Week” featuring the latest features. When we roll out new functions and enhancements – some of which are sponsored by the Austrian Armed Forces – we highlight them in the “Tip of the Week.”

But we also cover usability topics – for example, how to enable the menu bar even when the tabbed interface is selected. How to use presentations across multiple screens, and so on and so forth. We’ve been doing these “Tips of the Week” for two years now, and they’ve been very well received. It’s a great communication tool for us.

A truly open document format requires free public availability, royalty-free standards, and no usage restrictions.

Organizations like the Open Knowledge Foundation and the European Union use several core rules to guarantee long-term data access, system independence, and freedom from single-vendor control.

Core Openness Criteria

• Public Specification: The complete format rules are published and easy for anyone to access.
• Royalty-Free: Patents or licensing fees cannot block developers from building compatible software.
• No Discrimination: Anyone can use the format for any purpose without needing special permission.
• Independent Control: A transparent, non-profit standards body manages future updates.

Recognized Frameworks

• The Open Definition: Specifies exact legal and technical terms for open works.
• European Interoperability Framework (EIF): Requires governments to use truly open formats for public documents.

Comparison of ODF and OOXML

When evaluated against the strict criteria for open formats, Open Document Format (ODF) and Office Open XML (OOXML) take fundamentally different approaches.

While both are recognized as official ISO standards, ODF fully satisfies the open standard criteria by design, whereas OOXML features structural and legal complexities that often limit true open implementation.

Comparison Table

Criterion	Open Document Format (ODF)	Office Open XML (OOXML)
Public Specification	Fully Transparent. Concise, streamlined specifications built using a simplified RelaxNG XML schema	Highly Complex. Over 6,000 pages of specifications containing fragmented legacy behaviors.
Royalty-Free Status	Unconditional. Managed under standard royalty-free parameters for universal software design.	Conditional. Covered under a non-revocable patent promise rather than a traditional license.
No Discrimination	Complete. Equal implementation across open-source and proprietary suites.	Functional Barriers. Biased toward Windows-centric legacy and platform-specific behaviors.
Independent Control	Vendor-Neutral. Managed entirely by OASIS	Vendor-Influenced. Maintained via ISO, but the structural core remains tightly bound to Microsoft.

Key Openness Differences

Public Specification & Transparency

• ODF: Conceived from the beginning to be a modern, clean XML specification. “ODF is the only openly available standard, published fully in a document that is freely available and easy to comprehend”, as noted by GranneBlog: https://blog.granneman.com/2009/02/06/odf-compared-constrasted-with-ooxml/
• OOXML: Designed primarily to map Microsoft Office’s old binary data into XML. It is split into Strict and Transitional variants. “Transitional is everything else: a vast catalogue of compatibility features, deprecated elements, platform-specific behaviours, and references to undocumented quirks of Microsoft Office versions from the 1990s.”, as noted by the TDF Blog: https://blog.documentfoundation.org/blog/2026/06/02/a-standard-in-name-only/

Legal & Intellectual Property Rules

• ODF: Utilizes a standard open-source framework. Anyone can implement ODF in a project without fearing intellectual property or patent litigation.
• OOXML: Relies on the Microsoft Open Specification Promise (OSP): https://en.wikipedia.org/wiki/Microsoft_Open_Specification_Promise. The OSP is a unilateral covenant not to sue, but it only covers developers to the extent that they precisely mirror the specification. Any implementation-defined deviations or edge cases may leave developers legally unprotected.

Technical Discrimination & System Control

• ODF: Avoids hardware-specific dependencies, ensuring that independent applications (like LibreOffice or Apache OpenOffice) can render the data uniformly.
• OOXML: Contains platform-specific elements tied closely to the Windows OS ecosystem. Because Microsoft Office has traditionally produced Transitional OOXML by default, third-party platforms encounter massive conversion obstacles when interpreting legacy binary elements or proprietary formatting definitions embedded within the file structure.

INTERESTING REFERENCE: the Italian definition

The document Linee guida su acquisizione e riuso di software per le pubbliche amministrazioni (Guidelines on the procurement and reuse of software for public administrations), published by AgID in 2021, define an open format in the glossary as follows (translated from Italian):

Open (data) format. This is a public, versioned data format that is comprehensively documented and has no implementation constraints. An open format is one recognised by a standardisation body and maintained collaboratively by several organisations that provide competing implementations, through a transparent process. The format must remain consistent with the declared version.

The guidelines are not an interpretive gloss issued alongside the statute. They are adopted in implementation of articles 68 and 69 of the Codice dell’Amministrazione Digitale, under express delegations contained in the statute itself. They also supersede the earlier AgID circular 63/2013 on the same comparative assessment.

The definition of formato aperto (open format) is therefore not a recommendation that happens to be well drafted. It is the operative legal definition for Italian public administration, and it acquires that force through the statute rather than in spite of it.

Here’s our summary of updates, events and activities in the LibreOffice project in the last four weeks – click the links to learn more…

• We had one update in July: LibreOffice 26.2.5, the fifth maintenance update to the LibreOffice 26.2 branch.

• We also said a big welcome to our new TDF members! Members – more formally known as the “Board of Trustees” – are a crucial part of The Document Foundation, the non-profit entity behind LibreOffice. They are people from across the globe who contribute time, effort and skills, whether on a voluntary or paid basis.

• Then there was another section from the TDF Annual Report 2025, Policy and Digital Sovereignty. This section looks at Germany’s IT Planning Council committing to ODF, the approval of ODF 1.4, and public migrations to LibreOffice.

• On a similar topic, we posted how proprietary formats have become Microsoft’s main tool for lock-in.

• Back to the software itself: we posted the LibreOffice State of the Project (July 2025 – June 2026), based on data from July 1, 2025, to June 30, 2026, extracted from the LibreOffice dashboard and the Matomo repository. This is full of statistics describing the health of the project and the community.

On 30 July 2026, the United States Cybersecurity and Infrastructure Security Agency published Open Source Software: Security Principles and Practices, a 31-page guidance document for federal civilian agencies. It is available at no cost and marked TLP:CLEAR, meaning it may be shared without restriction.

The document is addressed to US federal agencies, and it fulfils obligations under two executive orders on federal cybersecurity. It covers four areas: using open source solutions, contributing to open source projects, producing open source software, and evaluating open source artificial intelligence models. The observations below concern the first three.

Its analytical content is not jurisdiction-specific, and public administrations elsewhere — including in Europe — will find that it articulates, in the vocabulary of risk management, several positions that the open source community has been arguing for two decades.

What the guidance actually says

The central claim is more precise than the headlines suggest. CISA does not assert that open source software is more secure than proprietary software. It states that OSS is “no more or less risky than other software,” and locates the difference elsewhere: with open source, an organisation can assess code quality and security directly, rather than relying solely on vendor assurances.

This is a claim about verifiability, not about defect rates. It is also the more defensible claim, and the more consequential one for procurement. An agency evaluating proprietary software is evaluating a vendor’s statement about its own product. An agency evaluating open source software is evaluating the product.

The guidance draws the corollary explicitly. Among the benefits it lists for federal agencies is reduced vendor lock-in: open standards and modifiable code, CISA writes, protect agencies from “proprietary dependency traps.” A national cybersecurity authority has placed lock-in inside a security document rather than a competition-policy one. That is a meaningful shift in where this argument is permitted to live.

The C4 Framework

The most practically useful part of the guidance is Appendix A, which sets out the C4 Framework for assessing whether an open source project is trustworthy. Its premise is that, because contributors may be pseudonymous and are bound by no delivery obligation, trustworthiness cannot be assessed from who produced the software. It must be assessed from how the software was produced — which open source development makes visible in a way that closed development does not.

C4 groups the evidence into four categories:

• Codebase — commit recency, known vulnerabilities, dependency currency.
• Community — number of maintainers, institutional structure, whether the project sits within a foundation.
• Conduct — whether there is a vulnerability disclosure policy, whether code review is required, whether maintainers merge their own commits, the licence, the code of conduct.
• Configuration — whether defaults are secure, and what hardening the software supports.

The framework is applied in five steps: identify measurable criteria, determine risk tolerance and weight the criteria, collect observations (with automated tooling where available), evaluate against each criterion, and compare the result to the tolerance.

We would encourage public administrations to apply this framework to LibreOffice. Every category can be answered from public evidence: a continuous commit history since 2010, a published security policy and disclosure process, mandatory peer review, an OSI-approved licence, a documented code of conduct, and a governance structure — The Document Foundation, a German Stiftung with an elected Board of Directors — that is a matter of public record rather than of assertion.

We would encourage administrations to apply the same framework to every candidate solution, including proprietary ones, and to note which questions can be answered and which cannot.

Contributing, and the support question

The guidance also addresses a question that public administrations regularly raise about open source adoption: who is responsible for fixes. CISA’s answer is that no single entity is obliged to provide them, and that agencies should therefore plan accordingly — assigning internal staff, contracting third parties, or both — while following two principles in dealing with upstream projects: collaborate rather than demand, and push fixes upstream.

This is a fair description of how the LibreOffice ecosystem works. Support, long-term maintenance, and custom development are provided by certified developers and certified migration professionals, whose contributions return to the shared codebase and benefit every other deployment. The guidance is right that this requires organisations to plan for it. It is also right that the resulting improvements are shared rather than captured.

CISA further notes that where a project becomes unmaintained, an organisation may as a last resort take over a fork. This option has no equivalent in proprietary software, where end of support arrives on the supplier’s schedule and offers no remedy at all.

A note on scope

The document does not name any product. CISA states explicitly that it does not endorse commercial entities, products, or services, and nothing in the guidance should be read as an assessment of any particular software. What it provides is a set of criteria. The observation that LibreOffice satisfies them is ours, and rests on evidence that anyone may check.

LibreOffice extensions are optional, third-party addons for the suite, that add extra functionality. Bora Yarkın has been working on a new extension for LibreOffice Impress, so let’s hear from him about it…

Tell us about it!

The extension lets you control a LibreOffice Impress presentation from your phone or any other device with a modern web browser.

When you start the remote, LibreOffice displays a QR code. Scan it with your phone and the presentation starts from the first slide. The phone interface then shows the current slide, presenter notes, elapsed time and navigation controls.

I tried to make the process as simple as possible: no separate mobile application and no manual pairing codes.

The remote can be opened from the Slide Show menu in LibreOffice’s top application menu bar—the menu alongside File, Edit, View and the other main menus.

This should not be confused with the Slide Show tab inside LibreOffice’s Tabbed user interface. LibreOffice’s UNO extension API does not currently let me add commands to that built-in tab. When using the Tabbed interface, the remote commands are therefore available under the Extensions tab instead.

The extension currently provides several connection modes:

• Local network: The phone connects directly to the computer running LibreOffice through its local IPv4 address. This is the main mode and the one I have tested most thoroughly.
• Direct IPv6: Works similarly, but uses an IPv6 connection. It is still marked experimental because my home internet connection is currently the only IPv6 network I can properly test with.
• Relay server: A small Python service that can be hosted on Linux or Windows. It is useful when the phone and computer are on different networks or when direct connections are blocked by carrier-grade NAT, firewalls or other network restrictions. It also supports multiple connections, so an organisation can host one relay server on its own infrastructure.
• LocalTunnel: An experimental fallback that creates an outbound connection through the LocalTunnel service. I consider this a last-resort option when the other connection methods are unavailable.

The compatible relay-server package is bundled with the extension. It can be downloaded or extracted directly from the Remote Settings window by selecting “Get Relay Server”. The package includes the required documentation and setup instructions.

To install the extension, download the .oxt file from the LibreOffice Extensions website or GitHub and open it with LibreOffice. It can also be installed manually through Tools > Extensions. After installation, restart LibreOffice if requested.

The extension includes translations for more than 100 languages and automatically follows LibreOffice’s interface language. English and Turkish are the two languages I have personally checked. Many of the other translations were created with ChatGPT, so I cannot guarantee their quality and would be very grateful for corrections from native speakers.

Why did you create it, and what was the process like?

The original inspiration came from Apple Keynote.

When Keynote is installed on both a Mac and an iPhone, the phone can be used to control the presentation while also displaying presenter notes. That feature completely changed the way I give presentations.

Over time, my slides became more professional and less text-heavy. Instead of putting everything on the slide, I started using the presenter notes almost like a teleprompter, with the text I actually planned to say. This helped move the audience’s attention away from reading the screen and back towards me.

That workflow worked perfectly for a long time, but I never really liked Keynote itself. I could not get used to its interface, and Apple’s decision to introduce paid features was the final reason for me to start looking for an alternative.

There were already several possible solutions, but none of them really worked for me.

LibreOffice previously had its own Impress Remote mobile application, but it has not been maintained for a long time and is no longer practical on many current devices and systems.

Browser-based presentation platforms can offer remote-control features, but I did not want my main presentation workflow to depend on an online service. They also do not offer the same flexibility as a full desktop office suite.

Microsoft Office was another possible option, but I am not a fan of Microsoft’s current direction, particularly the increasing integration of Copilot throughout its products.

OnlyOffice Desktop Editors is a good alternative and I used it for a while, but I encountered several bugs and eventually needed features it did not provide.

That brought me to LibreOffice, which I now find more useful and capable than the other office suites I tried. The only thing missing was the remote-presenter experience I had become dependent on with Keynote.

So I decided to build it myself.

I work mainly in IT and I am familiar with programming, but I would not describe myself as an advanced software developer. Before starting this project, I knew almost nothing about LibreOffice’s UNO API.

I began with ChatGPT. I defined the architecture, features, user interface and constraints myself—including requirements such as localisation being mandatory—and used AI to help me understand UNO and implement the code. The result turned out much better than I expected.

The extension was originally only a personal project. The first version was very basic; the web interface did not even have a back button. I had no intention of publishing it. Once it started working reliably, however, I realised that other LibreOffice users might want the same experience. I decided to take the project more seriously and turn it into a complete extension rather than something that only worked on my own computer.

That meant adding a more polished phone interface, connection settings, QR-code generation, IPv6 support, the relay server, LocalTunnel support, localisation, documentation, error handling and packaging.

Publishing it on the LibreOffice Extensions website was much easier than I expected. I created an account, created the project page, entered the information, uploaded the package and submitted it. After roughly a day of review, the extension was available publicly.

How can people help with testing and further development?

The source code and issue tracker are available on GitHub. The repository includes templates for bug reports, feature requests and pull requests.

My main development and testing setup is macOS with an iPhone. I have also tested the extension on Windows and Linux, but those tests were performed under less-than-ideal conditions, including virtual machines, Remote Desktop sessions and a headless Windows Server installation.

Because of that, testing on real Windows and Linux desktop systems would be especially useful.

The areas where community help would be most valuable are:

• Testing different LibreOffice versions
• Testing Windows, Linux and different macOS versions
• Testing Android devices and different mobile browsers
• Testing IPv6 connections between genuinely separate networks
• Testing the relay server in real-world and organisational environments
• Testing unusual firewall, VPN, NAT and carrier network configurations
• Reviewing and correcting translations
• Improving the documentation
• Reporting bugs and suggesting features
• Contributing fixes through pull requests

The local IPv4 mode has been tested extensively across different local networks, internet providers and VPN configurations. The IPv6, relay-server and LocalTunnel modes need broader community testing before I would consider them fully proven.

When reporting a connection problem, including the operating system, LibreOffice version, browser, phone type, selected connection mode and basic network configuration would help enormously.

The project started because I wanted this functionality for myself. Now I would like to make it reliable enough that other LibreOffice users and organisations can confidently use it for their own presentations.

Today we’re talking to Karl-Heinz Gruner, who has been supporting the LibreOffice community at events in Germany and recently became a member of The Document Foundation, the non-profit behind the suite:

Tell us a bit about yourself!

I live in Middle Franconia, near Nuremberg. In my spare time, I enjoy riding my motorbike, even though I haven’t been getting out on rides as much as I’d like at the moment. I find hiking in the region a great way to unwind. Being active in the fresh air brings me peace and relaxation, whilst also giving me space to come up with new ideas.

Professionally, I have worked extensively with office applications from various manufacturers – both from a user’s perspective and in the context of supporting other users. A particular focus of my involvement is my work with the local Linux User Group. There, I focus on open-source software solutions, sharing experiences and imparting practical knowledge.

For what are you using LibreOffice right now?

My personal curiosity and interest in practical IT solutions prompted me to carry out a fundamental modernisation of an association’s accounting system.

The starting point was an outdated spreadsheet program that was used to create entries, reports and statements. Initially, the idea was to migrate this solution to LibreOffice Calc, making it clearer and more future-proof.

However, during the analysis, it became clear that simply revising the existing spreadsheets would not be sufficient. Consequently, the decision was made to switch to a more up-to-date system with more comprehensive functions within the existing IT environment. A key outcome of this process is the use of a comprehensive application for administration and communication.

In addition to this, I developed a training programme for the adult education centre to focus on a specific area: the professional design of documents using forms and mail merges.

What do you plan to do in the future?

Looking to the future, I believe it is particularly important to convey information through a variety of channels. Modern software offers a wide range of functions, which many users initially find difficult to get to grips with.

It is therefore crucial to break down reservations and barriers to access. Potential users should be provided with clear information, given practical support and encouraged to try things out for themselves. Software and digital services must remain not only functional but also appealing.

For me, this means continuing to share knowledge through talks and training sessions, explaining practical applications using concrete examples, and convincing users of the benefits of open solutions.

My guiding principle is: inform, provide practical support, and spark interest.

Many thanks to Karl-Heinz for his help! All contributors to LibreOffice are welcome to become members of TDF

The question arises naturally for anyone who chooses the standard format over the proprietary one: why do office suites that use OOXML as their native format handle ODF in ways that range from poor to appalling?

The two most obvious answers are these: vendors have neglected the format, treating it as an afterthought, or they are quietly working to discredit the very idea of transparent interoperability, through support so bad that it demonstrates the format “does not work”.

Both answers are too simplistic. The reality is that three distinct mechanisms are at work, applying to different vendors in different proportions and ultimately converging on the same outcome.

A challenge that is not a challenge

Reading and writing ODF faithfully, in isolation, is genuinely feasible: the format is completely and openly specified, and there is no equivalent of OOXML’s notorious legacy compatibility flags, which refer to undocumented behaviours of old Microsoft products that only Microsoft can reproduce.

A competent development team is able to implement ODF correctly on the basis of the ODF specification alone.

An office suite, however, does not implement a format in isolation: it has an internal, in-memory representation of the document. Loading a document is a mapping into that representation, and saving a document is a mapping out of it.

Fidelity is greatest when the internal model is congruent with the document format. LibreOffice’s model is essentially ODF, which is why, in this context, ODF is genuinely native.

When a suite’s internal model has the shape of OOXML, ODF stops being native and becomes an external import that must be converted to and from a representation built for a different format.

Take an ODF feature that OOXML lacks: the ODP field that displays the total number of slides. The instructive part is that the information itself is not missing from a PPTX file. The package enumerates every slide, and the count is available to any program that opens it. What OOXML provides no way to express is the statement that this number is the total. There is a field for the current slide number and none for the count, and Microsoft’s own guidance is to type the figure into a text box and keep it up to date by hand, which is a precise description of not having a field at all. Every published workaround is a macro or an add-in that computes the number once and writes it out as fixed text.

So when an ODP file carrying that field is opened in an OOXML-based editor, what is lost is not the data but the instruction. The number survives. The fact that it was calculated does not, and from that moment the document no longer knows how long it is.

The reverse direction fails more quietly, and therefore worse. A slide count exported from Impress to PPTX has to be written out as fixed text, so the presentation is correct on the day it is converted and wrong the first time a slide is added or removed. A number that has stopped being calculated but still looks plausible is more damaging than a visible gap, because nothing in the document signals that it needs checking.

An ODF-based editor handles the reverse case in an entirely different way. When it encounters a feature present in one format and absent from the other, it sets the data aside rather than discarding it, and restores it when the document returns to OOXML. In LibreOffice this mechanism has a name, the grab bag, and it is a documented part of the import filters rather than an incidental behaviour.

The difference does not lie in the quality of the import filter, but in the fact that the architecture was designed to hold the meaning of the other format.

This matters, because it means that poor ODF support in OOXML-based suites is largely overdetermined before the question of motive even arises. The difficulty is not absolute, but relative to the architecture the vendor has chosen.

Three mechanisms

First: the bet on a reference format. Some suites do not consider ODF at all, because they have built their value proposition on the other format.

OnlyOffice is the clearest case, because it was built around OOXML and converts every other format into that model, so ODF is a second-class import and export format by design.

WPS Office is software created to open docx, xlsx and pptx files faithfully. Its ODF functionality derives from the add-in of Microsoft’s own OpenXML project and was integrated into the application only in May 2022, as a conversion layer written for ODF 1.1, which is to say for the 2007 revision of the standard. Fifteen years of delay were built in on the day of release.

Google Workspace is a variant of the same logic rather than an exception to it. Its internal model is neither ODF nor OOXML but a proprietary web representation, and both formats reach it through a conversion layer. For a public administration the consequence is identical: the open standard is an export target, not the substrate the software thinks in.

For these vendors, ODF was never part of the strategy. Their proposition is to open Microsoft documents in something other than Microsoft Office, and to make them look right, so poor ODF support is the direct consequence of the strategy.

Second: deliberate underinvestment. This is probably a cause that cuts across the whole office suite sector. Although ODF is easier and cheaper to implement correctly, the process still involves development, quality assurance and maintenance costs and timelines, in order to keep pace with a continuously evolving standard.

If a vendor’s users mostly exchange docx files, the marginal commercial value of excellent ODF support is close to zero, so ODF is first implemented at the minimum level and then quietly left to rot.

The perception that ODF support does not matter is itself a consequence of a single company’s market dominance, and its effect is twofold. Lock-in becomes a software feature that the market regards as entirely normal, and ODF acquires a reputation for fragility that no deliberate campaign was required to produce.

Third: deliberate disqualification. This mechanism is real, and it concerns Microsoft itself, with Service Pack 2 for Office 2007. The ODF support it shipped failed in two opposite directions at once.

When reading an ODF spreadsheet produced by another application, Excel silently stripped out the formulas and kept only the last value each cell had held, reducing the document, in Rob Weir’s assessment at the time, to a mere “table of numbers” with the calculation logic gone. When writing, Excel placed formulas in an Excel namespace that was neither the one used by OpenOffice and the other ODF applications nor the OOXML one. Applications that checked the namespace rejected the document outright; those that did not check it displayed a corrupted file showing neither the formula nor the value correctly.

This is a textbook mechanism for discrediting interoperability: meeting a format requirement with an implementation that conforms only on paper and produces visibly broken files, demonstrating to every observer that ODF does not actually work.

At the time, Microsoft argued that the ODF standard did not define spreadsheet formulas, which arrived only with ODF 1.2, and that there was therefore no reference to follow. The argument does not survive Microsoft’s own reply. Responding publicly to Weir, Microsoft’s evangelist Doug Mahugh set the two behaviours side by side: faced with the same unrecognised formula syntax, IBM Lotus Symphony preserved the formula markup, while Excel preserved the cached values. Neither application had a specification to follow. Only one had an architecture with somewhere to put what it did not understand.

It is worth noting what Excel kept. Not the formula, but its last result, which is the same reduction we saw with the slide count, in a different application. A model shaped by OOXML retains the value and loses the computation that produced it, and a document reduced to its last results is a document that has stopped being able to correct itself.

That episode is seventeen years old, and it would be easy to set it aside as history. Microsoft Office today declares support for ODF 1.4. But what improved is the nominal conformance, not the architecture. The internal model is still OOXML, and every ODF document that passes through it is still a translation.

The synthesis

Poor ODF support is not a technical verdict on the format, but the visible shape of a market organised around the dominance of a single vendor, and that shape did not come about by chance.

For European public administrations, this redefines the practical question, because the interoperability problems they encounter when they try to migrate to the open standard ODF are not caused by ODF, which is entirely ready. They are evidence that most of the available tools were designed to be native to somebody else’s format, and that the one vendor with the power to change this situation has repeatedly chosen not to.

The precarious state of ODF support in the market is not a reason to hesitate over adopting the standard, but the strongest possible reason to mandate it, and to mandate it precisely.

The question that protects a public body’s documents, and its sovereignty over them, is not whether ODF is supported, but whether that support is native, that is, whether the software’s own internal model is the open standard, or the standard is merely a foreign element inside an engine built for something else.

The document format is the substrate of administrative continuity and public memory. Choosing tools for which the open standard is native is not a preference between equivalent options, but the difference between owning your documents and renting access to them from whoever controls the format in which they are actually written.

On 13 October 2026, Microsoft ends support for Office 2021. No more security updates, no more fixes, no more assurances. The software will still launch. It will still open your files. But from that date it becomes a liability rather than an asset — and the only sanctioned path forward runs through a subscription.

This is not a bug in the model. It is the model.

Support that does not expire

LibreOffice has no end-of-support date, because there is no vendor with the power to declare one. The code is public. The development is community-driven and foundation-governed. When a release cycle closes, the next one is already available, free, to everyone — not to those who renewed.

The distinction matters more than it appears. Microsoft’s lifecycle policy is a commercial instrument: the date is chosen, not discovered. It marks the moment when continuing to use software you paid for becomes unwise, and it exists to convert perpetual licences into recurring revenue. LibreOffice cannot issue such a date because no one holds the authority to issue it.

Ownership of documents, not just access to them

A support deadline is the visible layer. Underneath it sits something more consequential: the format your documents are written in.

LibreOffice uses the OpenDocument Format (ODF), an ISO standard maintained by OASIS and implemented by multiple independent applications. The specification is public, complete, and readable. Anyone can write software that opens an ODF file correctly — today, or in forty years, using tools that have not yet been written.

OOXML, despite carrying an ISO number, is not comparable in practice. The standard that was approved and the format that Microsoft Office actually writes have diverged. Independent implementations remain approximations. This is why round-tripping a complex document between suites degrades it, and why the degradation is always the fault of the software that did not write the format in the first place.

The consequence is simple. If your archive is in OOXML, your ability to read it depends on a commercial relationship with a single company continuing indefinitely. If your archive is in ODF, it does not.

Documents are software

A modern document is not a page. It is a structured artefact: markup, style definitions, embedded objects, references to fonts, scripts, conditional logic, external data. It is executed by an application in exactly the way a program is executed by a runtime.

We accepted decades ago that critical software should not be built on formats and interfaces controlled by a single vendor. Documents have escaped that scrutiny only because they look like paper. They are not paper. The same argument that makes open standards essential for software makes them essential for the files that record contracts, medical histories, legislation, research, and institutional memory.

Costs that stop compounding

The licence saving is real but it is the least interesting part of the calculation. What changes structurally is the removal of a recurring, unilaterally repriceable line item from the budget — one that has risen repeatedly and will rise again, because the customer has no alternative to negotiate with.

Migration has costs. Training, template conversion, macro rewrites, integration work. These are one-off and quantifiable. Subscription is perpetual and is not.

Independence from the deployment model

Support deadlines are increasingly used to move users from local installation to cloud service. That transition is not neutral. It changes where documents reside, which jurisdiction governs them, who can be compelled to disclose them, and whether work is possible when connectivity is not.

LibreOffice runs locally, on Windows, macOS, GNU/Linux, and in a browser via LibreOffice Technology-based online solutions — as a choice, not as a condition of receiving updates.

What October 2026 actually asks

The deadline poses a question that the deadline itself cannot answer: should the readability of your organisation’s documents in 2046 depend on decisions made by a company in 2026?

If the answer is no, the migration is not a reaction to an end-of-support notice. It is the correction of a dependency that should never have been accepted.

Support ends on a date someone else chooses. Ownership does not end at all.

LibreOffice is developed by The Document Foundation, a non-profit organisation based in Berlin, and is available free of charge at libreoffice.org. The Document Foundation publishes a LibreOffice Migration Protocol for organisations planning a structured transition.

Digital sovereignty is not about owning everything, it is about ensuring that nothing essential can be taken away.

That single line settles more arguments than it first appears to, because it disqualifies the two positions that dominate the debate. One side imagines sovereignty as control. The other imagines it as choice. Both are talking about something real, and both have mistaken a part for the whole.

The control camp misreads the goal

The instinct to equate sovereignty with control is understandable. Sovereignty, in its older political sense, was control: borders, currency, the monopoly on force. So when the word migrates into the digital domain, people reach for the same picture: own the servers, hold the data, build the stack, depend on no one.

The trouble is that this picture is both impossible and beside the point.

It is impossible because no institution, and certainly no continent, is going to reimplement the entire computing stack from silicon upward. The dream of total self-sufficiency is not sovereignty, it is autarky, and autarky has failed everywhere it has been seriously attempted.

A Europe that tried to own everything would spend a generation rebuilding inferior versions of things that already work, and would be no freer at the end of it.

But the deeper problem is that control is the wrong target even when it is achievable. An institution can own the building and still be a tenant of the lock.

A public administration can run its own data centre, on its own soil, under its own staff, and still find that every document it produces is hostage to a format only one vendor fully understands. The hardware is sovereign. The institution is not. Control over the container tells you nothing about who controls the contents.

This is why the control framing quietly concedes the argument before it begins. It accepts that sovereignty is about what you hold, and so it can always be answered with “but you cannot hold all of it”, which is true, and which is why the framing loses. Sovereignty was never about the holding.

The choice camp misreads the threat

The opposite error is more fashionable and, for that reason, more dangerous.

Here the argument runs: sovereignty simply means freedom to choose. A sovereign buyer surveys the market and selects the best tool for the job, and if the best tool happens to be proprietary, so be it. To exclude proprietary software on principle, this camp says, is itself a kind of unfreedom, an ideology dressed up as independence. Real sovereignty, they insist, is vendor-neutral.

It is a seductive argument because it borrows the language of liberty. But it confuses a choice made today with a choice that remains available tomorrow, and that confusion is the whole game.

Consider what “choosing” a proprietary, closed-format platform actually buys you.

On the day of purchase, you have exercised your freedom: you compared options and picked one. But every document, every workflow, every trained habit that follows accumulates inside a system that only its owner can reproduce.

Five years later, when the licence terms change, or the price rises sharply, or a feature you depend on is discontinued, or the company is acquired and the product withdrawn, you discover that your freedom to choose has quietly expired. The market has not removed your options on paper. It has removed the ground beneath all but one of them.

This is the trap the choice framing cannot see, because it measures freedom at the moment of decision and never at the moment of exit. A choice you cannot reverse is not really a choice, it is a commitment wearing a choice’s clothes. Sovereignty has always been about the capacity to reverse, to leave, to change one’s mind, to refuse a deal that has turned bad. A buyer who cannot say no later was never sovereign to begin with.

What is actually essential

So if sovereignty is neither owning everything nor choosing freely among everything, what is left?

What is left is the thing the opening sentence points to: ensuring that nothing essential can be taken away.

The word doing the work there is essential. An institution does not need to own the cloud, it needs to be sure that if a provider vanishes tomorrow, its data does not vanish with it.

It does not need to forbid proprietary tools it needs to be sure that the things it commits to those tools – its records, its contracts, its citizens’ files – remain readable, movable, and re-creatable by someone other than the vendor who sold it the tool.

Sovereignty is not a wall around one’s possessions. It is a guarantee about one’s exits.

This is why open standards, and not ownership, are the real substance of digital sovereignty, and why open standards alone are not even enough.

A format must do two things. It must persist: it must be readable in ten years without asking permission. And it must be reimplementable: anyone, in principle, must be able to build a tool that reads and writes it, without reverse-engineering, without a licence, without the original vendor’s blessing.

Persistence without reimplementability is a museum exhibit: you can look at your data, but only one company can do anything with it. Reimplementability is what turns a surviving file into a living, portable, sovereign asset.

The shape of the mistake

The control camp and the choice camp look like opposites. One wants to build a fortress, the other wants to shop in an open market. But they make the same underlying error: they locate sovereignty in the present tense: in what you hold now, or what you select now.

Sovereignty lives in the future tense. It is the answer to a question you have not yet had to ask: when this provider fails me, what survives? If the honest answer is “everything essential, and I can take it elsewhere,” you are sovereign, whatever brands happen to sit on your desks today.

If the honest answer is “that depends on whether they let me,” then you are not sovereign, no matter how much you own or how freely you chose.

A closing note: this is not an abstract argument

Everything above can be stated in three letters and a contrast.

The OpenDocument Format (ODF) is what reimplementability looks like in practice. It is a published ISO standard that any developer can implement fully, without permission and without payment, and many independent applications do.

A file saved in ODF is not merely yours, it is re-creatable by anyone, which is precisely what makes it safe to entrust your institution’s memory to it. Nothing essential can be taken away, because nothing essential depends on a single vendor.

OOXML is the cautionary half of the contrast. It exists as a standard, and in that narrow sense a file saved in it will not “disappear.”

But the format as actually deployed carries provisions and behaviours that only its originator implements completely, and the effect is that full fidelity remains the property of one vendor. This is persistence without reimplementability, or the museum exhibit. You may keep the file forever and still be unable to do anything sovereign with it.

Which is why the most consequential decision a sovereignty-minded institution makes is not where its servers sit, nor which brand of software runs on them, but which format its documents are native in.

A platform that can export to an open format but lives, by default, in a proprietary one has granted its users persistence and quietly retained sovereignty for the vendor. The files will survive. The dependency survives with them.

Choose the native format that anyone can re-create, and the rest of the sovereignty question becomes manageable. Get that one choice wrong, and no amount of owned hardware or vendor-neutral procurement will buy back what has been signed away.

Nothing essential can be taken away. For documents, that sentence has a name, and the name is ODF.

This article was inspired by Roberto Di Cosmo’s formulation of digital sovereignty as the capacity to ensure that nothing essential can be taken away.

Berlin, 23 July 2026 – The Document Foundation today announced the release of LibreOffice 26.2.5, the fifth maintenance update to the LibreOffice 26.2 branch. Building on the major feature release published on February 4, 2026, this update delivers targeted bug fixes and stability improvements contributed by a global community of developers and QA engineers.

Skia rendering on macOS and Windows, introduced for better graphics performance, has now been put under experimental mode to avoid crashes and hangs reported by several users after the upgrade from a previous LibreOffice version.

LibreOffice 26.2.5 is available for immediate download at www.libreoffice.org/download/ for Windows, macOS, and Linux.

Users of LibreOffice 25.8.x must now update to LibreOffice 26.2.5 as LibreOffice 25.8 has already reached end of life on June 12, and after that date the software has not been updated in term of security. In late August 2026, The Document Foundation will announce LibreOffice 26.8.

Love LibreOffice? Got a passion for marketing, media, public relations and creating great campaigns? We are The Document Foundation (TDF), the non-profit entity behind LibreOffice. We’re passionate about free software, the open source culture, and bringing new people with fresh ideas into our project.

To help to raise awareness of LibreOffice and support the marketing community with its work, we are looking for a Marketing and Communication Professional, to start as soon as possible.

Here’s what you’ll do

• Work with our graphics design agencies and create content showcasing new and updated features in LibreOffice (blog posts, social media posts, videos, website pages…)
• Draft and edit press releases and cross-channel content
• Work directly with the senior communications lead on the strategic side: media relations, campaigns, and texts that carry TDF’s positioning
• Improve media relations with EU and policy press, along with the FOSS and technology press
• Maintain the press-contact database and mailing lists
• Media monitoring, coverage tracking, and basic reporting
• Edit contributed and translated texts from our wider marketing community
• Track the effects and results of marketing campaigns on downloads and donations
• Logistical coordination of event communication

What we want from you

The role is built around a two-year trajectory: full operational ownership from the start, and a growing share of strategic work as the senior lead reduces involvement through 2028. The person we are looking for is reliable and largely self-directed on operational work; collaborative and open on the strategic side, where TDF’s positioning is developed jointly during the transition. Someone who genuinely wants to grow into a strategic communications role, and is content to build toward it steadily rather than assume it on arrival.

• Excellent communication skills, especially in written English
• Working fluency in at least one other major European language; more is a clear advantage
• A journalistic or public-relations instinct: a feel for what makes news, an ear for what a reporter will actually use, and either an existing network of press contacts or the demonstrated ability to build one
• The ability to adapt communications across different channels: the TDF blog, social media, Reddit etc. – while maintaining a consistent style and tone
• Good team-playing abilities

Familiarity with free software, open standards, and the digital-sovereignty debate is welcome, but not essential. This can be learned in the role, and genuine curiosity about it matters more than prior expertise. Also beneficial is experience in a non-profit, foundation, or other mission-driven organisation.

As always, TDF will give some preference to individuals who have previously shown a commitment to TDF, including but not limited to members of TDF. Not being a member does not exclude any applicants from consideration.

Join us!

All jobs at The Document Foundation are remote jobs, where you can work from your home office or a co-working space. The work time during the day is flexible, apart from a few fixed meetings. The role is offered as full-time (ideally 40 hours per week). While we prefer full-time for the role, part-time applications, or proposals to grow the hours over time, will be considered. Candidates that are resident in Germany will be employed directly by TDF. Otherwise, external payroll services will be used if available in the candidate’s country of residence.

Are you interested? Get in touch!

TDF welcomes applications from all suitably qualified persons regardless of their race, sex, gender, disability, religion/belief, sexual orientation or age. Don’t be afraid to be different, and stay true to yourself. We like you that way!

We’re looking forward to receiving your application, including information about you (your resume), when you are available for the job, and of course your financial expectations. Please provide details about your experience and send us an e-mail to marketingjob@documentfoundation.org no later than August 31, 2026 (end of day, Berlin time). If you haven’t received feedback by September 30, your application could not be considered.

Also note: we only accept applications from the applicant, and not from any intermediary. We do not accept agency resumes. Please do not forward resumes to any recruiting alias or employee.

We are releasing the quarterly updated State of the Project Slide Deck, based on data from July 1st, 2025, to June 30, 2026, extracted from the LibreOffice dashboard and the Matomo repository.

During the 12 months 309 developers worked on the source code, adding 11.464 new commits (Git): 238 volunteer developers (77%) provided 2.028 commits (18%); 11 developers from The Document Foundation (4%) provided 4.501 commits (39%), and 60 developers from 8 ecosystem companies (19%) provided 4.935 commits (47%).

The slide deck is also a tribute to the 20 top Git committers, the 20 top Gerrit committers, the top 20 Bugzilla issue submitters, the top 20 people answering on Discourse, and the top 20 translator on Weblate. To all of them and to all the other contributors, thank you.

Looking at donations and downloads, the trend during the first six months of 2026 confirms the positive trend started in early 2025. Donation figures refer to the number of transactions and not to their amount, which is available via the ledgers published on The Document Foundation website.

You are invited to look at the slides, and download the file to compare it with the previous slide deck published in January and April. The next slide deck which will be available in October and will cover the 12 months between October 1st, 2025, and September 30, 2026.

We have started to publish these slide decks in January 2026, to provide a transparent overview about the progress of the project through some of the most significant measures of development, downloads and donations data collected by the marketing team at TDF.
