LibreOffice Conference and External Events – TDF Annual Report 2025

2026-06-23

This is part of the Annual Report 2025 from The Document Foundation, the non-profit that coordinates the LibreOffice project and community. More will be posted soon…

LibreOffice Conference

The LibreOffice Conference was the annual get-together of the worldwide LibreOffice community, bringing together developers, contributors, and users. The 2025 event was held in Budapest, Hungary, from September 3 to 5, and was preceded by a community session.

The main conference featured 53 sessions spread over three days. It kicked off with a welcome and housekeeping session, followed by an opening speech from Eliane Domingos from TDF’s Board of Directors, and a welcome speech from the university that hosted the event.

After that, the talks began across several different tracks, including the Open Document Format, advocacy and marketing, development and extensions, UX and design, and more. The full list of talks can be found on https://events.documentfoundation.org/libreoffice-conference-2025/schedule/. There was also a notable talk from the Austrian military (Bundesheer) about their migration to LibreOffice and the new features they funded.

The event finished on Friday with a lightning talks session, followed by the closing address and a celebration for the 15th anniversary of LibreOffice. But the conference was more than just talks: there was a community dinner as well.

Now the community is looking forward to 2026’s LibreOffice Conference. The event will take place in Pordenone, northern Italy, from September 10 to 12, and the Call for Papers is currently open.

In addition to the main LibreOffice Conference, there was the LibreOffice Asia Conference 2025, which took place in Tokyo, Japan, from December 13 – 14. Speakers and guests from around the world discussed topics specific to Asian communities, such as complex text layout (CTL) and CJK (Chinese, Japanese, Korean) language support, and marketing LibreOffice in specific countries.

There was also the sixth edition of the Latin American LibreOffice Congress, held in Habana, Cuba, from October 6 to 9. LibreOffice project activities was concentrated on the opening day, October 6, and in the special session “LibreOffice Congress and Technological Sovereignty”, on the 8th. With the remaining days available, the organisers articulated a parallel agenda of activities, with visits and strategic meetings with managers and professionals from governmental and community areas.

TDF at External Events

Throughout 2025, members of The Document Foundation and the LibreOffice community attended many other events around the world. The first big event was FOSDEM, held in Brussels in early February – the biggest meetup of free and open source software developers in Europe. As usual, the LibreOffice community was present with a stand, merchandise, stickers, flyers, clothing and more. Attendees came by to talk about the project, report issues and make suggestions.

In late April, the Augsburger Linux-Infotag 2025 event took place in southern Germany, and LibreOffice was present with a stand and merchandise. Another German event was the Univention Summit 2025: it took place on January 23 and 24 in Bremen, and the LibreOffice project was present and met with the people overseeing the migration to LibreOffice in the northern German state of Schleswig-Holstein.

Italian community members attended the Linux Arena event from April 25 – 27 in Pordenone. They had a LibreOffice stand with a 32″ monitor, showing an Impress presentation about LibreOffice on a loop. At the stand they met different interested people – some of whom they already know since they visit the fair regularly, while others they saw for the first time. There was curiosity about LibreOffice, and this time the stand personal noticed an increasing demand about AI integration and related plugins. The LibreOffice coffee/beer mats were very much appreciated by visitors to the stand.

Later in the year, Community members in Nepal tuned in to an online call and turned Software Freedom Day 2025 into a success. Birendra Open Source Club – one of the student clubs and LibreOffice project contributors in Nepal, with support from Liaison Suraj Bhattarai and other key open source clubs, hopped onto Discord on 20 September.

On October 4 and 5, the LinuxDays 2025 event took place at the Faculty of Information Technology (Czech Technical University) in Prague. It combined stands for free and open source software projects with workshops and talks, and the Czech-speaking LibreOffice community was there.

Members of the Indian LibreOffice community celebrated Document Freedom Day in Noida on 29 March. The event featured a few talks on free software such as OpenStreetMap, Prav and KDE, and also a lawyer told attendees how they manage all their clients’ data with free software and keeping their privacy in mind. LibreOffice merchandise was distributed at the sticker table.

LibreOffice releases, features, QA and accessibility – TDF Annual Report 2025

2026-06-16

This is part of the Annual Report 2025 from The Document Foundation, the non-profit that coordinates the LibreOffice project and community. More will be posted soon…

Releases of the Year

LibreOffice’s release plan works on a time-based release schedule, with major updates every six months (typically in February and August). So in other words, there are two new versions of LibreOffice per year. Many other FOSS projects adopt a similar time-based approach, and since 2024, LibreOffice has used a “year.month” versioning scheme – so LibreOffice 25.2, for instance, was released in the second month (February) of 2025. This versioning scheme helps users to see how old (or new) their currently installed version of LibreOffice is.

In addition to the major upgrades, there were monthly smaller “point” releases, mainly fixing bugs, compatibility issues and security vulnerabilities.

Major Feature Highlights

LibreOffice 25.2 was released on February 6. It introduced the ability to read and write ODF version 1.4, alongside numerous interoperability improvements with proprietary OOXML documents. It became possible to automatically sign documents after defining a default certificate. Additionally, Windows 7 and 8/8.1 were designated as deprecated platforms, with support scheduled to be removed in version 25.8, and extensions and features relying on Python ceased to work on Windows 7.

In LibreOffice Writer 25.2, improvements were made to Track Changes management to better handle a large number of changes in long documents. Comments were tracked in the Navigator when the focus was moved into them, while resizing the area containing comments showed a visual guide. Options were added to set a default zoom level for opening documents, which overrode the level stored within the documents themselves. It also became possible to delete all content of a specific content type, excluding headings, via the Navigator.

In LibreOffice Calc 25.2, a “Handle Duplicate Records” dialog was added to select or remove duplicate records. Both the Function Wizard dialog and the Functions Sidebar deck received improvements to searching and user experience. Solver models could be saved into spreadsheets, and the Solver became able to provide a sensitivity analysis report. New sheet protection options were also added relating to Pivot Tables, Pivot Charts, and AutoFilters.

Furthermore, many improvements were made to all Impress templates, which received visible elements, such as the font colour being set to black, in Master Notes and Handout. Objects could be centred on the Impress slide or Draw page in a single step, and the automatic repeating of slides could be activated in windowed mode. Finally, overflowing text in presenter notes was no longer cut off when printing.

Meanwhile, LibreOffice 25.8 was released on August 20. It brought new performance and features to the suite. In the User Interface, the Welcome/What’s New dialog began offering access to the user interface picker and appearance options, which allowed new users to leverage LibreOffice’s flexible UI and personalise the look and feel according to their preferences. The release also provided better interoperability with Microsoft Office files, offering more accurate handling of DOCX, XLSX, and PPTX files with fewer formatting issues, thanks to changes such as:

A complete overhaul of word hyphenation and spacing
Font management in Impress updated to be compatible with PowerPoint files
The addition of new functions in Calc: CHOOSECOLS, CHOOSEROWS, DROP, EXPAND, HSTACK, TAKE, TEXTAFTER, TEXTBEFORE, TEXTSPLIT, TOCOL, TOROW, VSTACK, WRAPCOLS, and WRAPROWS

There were, of course, other important new features, such as the ability to export to the PDF 2.0 format, and several new ScriptForge library services.

Performance

Throughout 2025, the LibreOffice community continued to work on improved performance in the suite. In LibreOffice 25.2, the speed of font previews in Calc was greatly improved. Additionally, the speed of saving from XLS to ODS was greatly improved after the impact of increasing the supported number of columns to 16k, and saving ODS files with large merged ranges became faster. Spreadsheets with lots of conditional formatting opened and saved much faster, while spreadsheets with lots of comments also saved much faster. Finally, the speed of loading XLS files was greatly improved after the impact of increasing the supported number of columns to 16k.

In LibreOffice 25.8, performance was upgraded so that everything ran faster, from startup to scrolling through large documents, with significant speed improvements delivered on less powerful machines. In benchmark tests, Writer and Calc opened files up to 30% faster. Optimised memory management allowed for smoother operation on virtual desktops and thin clients.

Quality Assurance

For every release, the LibreOffice Quality Assurance community produced Alpha, Beta and Release Candidate versions, giving users the chance to test the software (and report bugs) well in advance of the final release. Throughout the years, thousands of bugs were confirmed, triaged and resolved. The QA team wrote monthly reports about its activity on the QA blog.

Accessibility

In LibreOffice 25.2, the Accessibility Sidebar featured improved warning and error levels, along with a new option to ignore specific warnings. Additionally, user interface elements were updated to report an accessible identifier that can be utilised by assistive technologies.

Platform-specific enhancements included on Windows, where accessibility was automatically enabled whenever a tool querids information on the accessibility level, and accessible relations were now correctly reported. Meanwhile, on Linux, the positions of UI elements, including those on Wayland, were accurately reported on the accessibility level.

LibreOffice 25.8 added an accessibility check for links and references in header/footer. Menus in the File ▸ Templates ▸ Manage Templates dialog became screen reader accessible on Windows. Support for the IAccessible2 “text-indent” attribute was added, which could be used by assistive technology like screen readers to report the indent of a paragraph’s first line. Additionally, the table design view in Base no longer became unresponsive when a screen reader was active on Windows. Finally, comboboxes and other controls inside toolbars were also represented in the accessibility tree of the application.

LibreOffice project and community recap: May 2026

2026-06-10

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 started May by announcing the new LibreOffice website. Our previous website was looking rather old and becoming difficult to maintain, so the team at TDF – with help of the wider LibreOffice community – has been working on a redesign, based on newer technology.

We reported back from the Augsburger Linux-Infotag, an event is all about Linux and free and open source software (FOSS) in south Germany, where the LibreOffice community was present.

Throughout May, we continued our regular article series about the Open Document Format (ODF): Thank you, on behalf of ODF, Twenty Years On, ODF Is Still the Only Open Standard for Office Documents, and the Only One Governments Can Trust, and ODF vs OOXML, an issue that should never have existed.

Then we announced projects selected for LibreOffice in the Google Summer of Code 2026, including: OpenType MATH; Improve word processor test coverage; and JPEG XL import support.

In the middle of the month, we announced LibreOffice 25.8.7, the final maintenance release of the LibreOffice 25.8 family. From here we will focus on maintaining the 26.2 branch, and are preparing for 26.8, our next major release (due in August).

The vast majority of income to The Document Foundation, the non-profit behind the LibreOffice project and community, is from donations from end users. We made a new video explaining how donations are used to support the community that makes the software.

Next, we started posting sections from TDF’s Annual Report 2025, starting with Native Language Projects. A huge thanks to the hundreds of people who make LibreOffice available is so many languages around the world! 😊

Then we announced our New Web and Mobile Strategy for LibreOffice. LibreOffice is a desktop application, and we will continue making it. But we have constant requests for web and mobile versions, so we’re looking into what we can do. We already have a more detailed proposal from the TDF team.

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.

Meet the team at The Document Foundation

2026-06-012026-06-07

LibreOffice is made by hundreds of people around the world, working on code, documentation, QA, translations, marketing, infrastructure and much more. Coordinating the project’s activities is the team at The Document Foundation, the non-profit behind LibreOffice. Let’s see what the team members do:

1. Christian Lohmaier, Release Engineer

Christian’s typical tasks include taking care of the continuous integration system (both the automation server and the build machines), managing the LibreOffice release process, handling app store updates with all the paperwork that entails, managing the technical side of language translations not only for LibreOffice, but for any translatable system we have and making sure our integration with payment platforms works smoothly. He has also been involved in creating and maintaining websites and web services.

Christian’s work is influencing the developer experience as well. In the past, LibreOffice’s Windows development setup was somewhat messy. After Christian introduced automation into the setup process with the help of WinGet scripts, there has been much less need for troubleshooting.

2. Dan Williams, Developer

Dan was involved in the Mac port back in the 2000s when LibreOffice was still called OpenOffice.org. For some months now he has been working for TDF on user interface and macOS tasks. He has done corrections to the handling of system UI themes, implemented support for special macOS keyboard shortcuts and macOS-specific menu items, fixed database links going missing from .ods files, and fixed an issue with printing notes from Impress presentations on macOS. His ongoing work includes experimenting with Qt UI on macOS and reworking the code for Notebookbar.

3. Florian Effenberger, Executive Director

Florian is one of the founders of TDF, and its Executive Director since 2014. He manages our worldwide team of 18 people, and deals with a variety of tasks in accounting, financials, taxes, budget, payroll, annual audit, banking, legal topics, employment and HR. He supports the board and the membership committee and onboards those new in office. He regularly gives presentations at events, is active in the German community and has written extensively about the tasks he is involved on our forum.

4. Guilhem Moulin, Infrastructure & Services

Guilhem is managing our servers and the approximately twenty web services needed every day by LibreOffice users and contributors. Major updates to the operating systems and the web applications require careful studying of what needs to be taken into account to ensure everything keeps operating smoothly. Often this goes into the level of studying individual code changes. Compatibility breakage has to be mitigated or at least communicated.

5. Heiko Tietze, UX Architect

Heiko is collaborating with user experience design volunteers in planning improvements to LibreOffice. Not being content with planning, he then goes and implements the proposals, either by himself or with help from others. Heiko always denies being a C++ developer yet inexplicably has over 700 LibreOffice code changes in his name. He has mentored in over a dozen Google Summer of Code (GSoC) and Outreachy projects, for example in the reworking of Table Styles and UI theming. Being an active mentor means that he is doing code reviews for new developers all year round as well as inventing new easy tasks.

A recent large-scale project of his is implementing vertical tabs in dialogs.

6. Hossein Nourikhah, Developer Community Architect

Over a hundred developers get their start in LibreOffice code every year. Facing seven million lines of code can be intimidating, so we have a tradition of providing a selection of tasks we call “easy hacks“. Hossein is tending to this catalogue of beginner tasks and reviewing the submitted code changes. Whenever a new developer has issues with setting up a development environment, he jumps in to help. He is also writing developer documentation on the TDF wiki and publishing blog posts about development.

He has mentored GSoC projects such as cross platform bindings for .NET and Python code auto-completion. His recent contributions include initial support for Qt 6 UI on Windows together with Michael Weghorn, based on earlier work by Jan-Marek Glogowski.

7. Ilmari Lauhakangas, Development Marketing

Ilmari is bringing in new contributors to quality assurance, design, C++ development and documentation. In a typical year he teaches nearly 200 people about getting involved in LibreOffice. He is also triaging (and sometimes fixing) bugs, doing web development, maintaining the wiki, doing code reviews and managing internship programs.

8. Italo Vignoli, Marketing & PR

Italo Vignoli is a founding member of The Document Foundation and the LibreOffice project, the Chairman Emeritus of Associazione LibreItalia, an Ambassador of Software Heritage, and a proud member of Free Software Foundation Europe (FSFE). He is a past board member of Open Source Initiative (OSI). Italo co-leads LibreOffice marketing, PR and media relations, co-chairs the LibreOffice Certification Program, and is a spokesman for the project. He also handles advocacy and marketing activities for the Open Document Format ISO standard.

9. Jonathan Clark, Developer

For the past two years Jonathan has been working on LibreOffice features in the categories of right-to-left scripts, complex text layout and Chinese-Japanese-Korean. In addition to numerous quality of life improvements, he has implemented support for Start/End paragraph alignment while making it the default instead of Left/Right, and made the CJK text grid compatible with Microsoft Word. On the mentoring side he is constantly reviewing code submissions from newcomers and was involved in the BASIC IDE object browser GSoC project.

Jonathan is currently looking into fundamental improvements in the LibreOffice user interface.

10. Juan José González, Web Technology Engineer

As mentioned earlier, TDF hosts a rather large number of web applications, some of them created from scratch. These custom web services include the Extensions and Templates site and the Crash Report site. Juan José has been heavily involved in redesigning and maintaining these two sites. He has also worked on sites for various LibreOffice conferences, improved our localisation tooling and created tools to combat spam in our forums.

11. Michael Weghorn, Developer

TDF wants LibreOffice to be easy to use for visually impaired people, and three years ago Michael was hired to make sure we always deliver accessible software. LibreOffice has lots of variety in its content types and user interface widgets. This means that we are sometimes testing the limits of accessibility APIs, which are also different per operating system. To ensure optimal results in LibreOffice accessibility, Michael is working with developers of toolkits such as GTK and Qt, and with developers of screen-reader applications such as Orca and NVDA.

At the moment Michael is working to bring LibreOffice’s Qt user interface support to the next level and seeing how it works on Windows.

12. Mike Saunders, Marketing and Community Coordinator

Mike is a long-time Linux and free software journalist, and joined the team in 2016 to work in the areas of marketing and community outreach. He helps to maintain the LibreOffice social media channels, interacting with users to encourage them to join the project and contribute. He also interviews community members, writes blog posts, works on videos and podcasts, and organises events.

13. Neil Roberts, Developer

Neil joined the team a couple of months ago to improve the scripting and API side of LibreOffice. He has implemented a new approach for Lua UNO API bindings, added QuickJS-based JavaScript bindings together with Stephan Bergmann and made it possible to create and edit Python macros via the Macro Organizer dialog.

Neil will also be collaborating with Michael Weghorn on user interface renovation projects.

14. Olivier Hallot, Documentation Coordinator

Olivier started contributing back in the OpenOffice.org days in 2001 as part of the Brazilian community and is one of the founding members of TDF. For ten years he has been leading the documentation effort for LibreOffice. The documentation team maintains several guide books, a huge collection of help articles, wiki pages and even tooltip texts seen within LibreOffice itself. Olivier has opinions on writing good release notes and is not shy to share them!

Olivier is also fixing UI issues and making sure everything works with regards to localisation.

15. Sophie Gautier, Foundation Coordinator

Sophie has been in the LibreOffice project since the beginning (and in OpenOffice.org before that), and helps with TDF administration tasks, such as organising meetings and managing the travel refund tool. In addition, she helps to organise the yearly LibreOffice Conference, and works with the localisation communities to make LibreOffice available in as many languages as possible.

16. Stephan, Administrative Assistant

Stephan helps with administrative tasks for the foundation, such as meeting minutes, accounting reports, donation queries, travel bookings, travel expense reimbursements, ordering equipment, issuing donation receipts, payment processing, and translations.

17. Vissarion Fysikopoulos, Developer

Having started about a month ago, Vissarion will focus on taking Base to the next level. The current development plan includes finishing the new Report Builder, polishing Firebird support and adding support for SQLite.

18. Xisco Faulí, QA Engineer

Xisco did a Google Summer of Code project for LibreOffice in 2011 and joined the TDF team in 2016 to work on QA (quality assurance). At first he was triaging bugs, but gradually moved to writing automated tests. By now he has added thousands of tests. He keeps LibreOffice’s hundred external dependencies up to date, fixes critical bugs, improves graphics support, helps with the release process, is involved in reviewing security reports and handles the crash report system alongside other automated systems related to guarding the quality of the software. He also mentors GSoC projects.

As mentioned, the team is just a small part of the overall LibreOffice community. Everyone is welcome to find out what you can do for LibreOffice – to learn new skills, meet new people, and be part of a project making software used by millions of people around the world!
