LibreOffice is the successor project to OpenOffice(.org), which in turn was based on StarOffice, a proprietary office suite developed in the 1990s. Learn more about the history here! And let’s hear from Stefan Soyka, who worked on StarOffice from 1990 – 1992…
I came from Berlin to Hamburg to work for Marco Börries in his Star Lab in spring 1990, together with my friend and study mate Stefan. Both of us joined the project more or less at the same time and shared the same first name, which caused some confusion at first.
The situation in Hamburg needs some explaining if you are new to it. The Writer application that is the foundation of what we use today is not the first Star Writer – but thesedays it is often referred to as Star Writer 6 or Star Writer Graphic. Marco’s company Star Division, based in rural Lüneburg not far from Hamburg, had developed and sold with considerable success a text processing application with the same name, that was an MS-DOS application based on a home-grown graphics framework. A team of freelance programmers was working on it under the lead of Sven-Ola Tücke.
This was also the tool we used to write the first drafts for specifications, by the way.
The old Star Writer had a solid fanbase and sold quite well even after Star Lab started in Hamburg. So it is fair to say that the money we burned in Hamburg was earned in Lüneburg.
Marco, however, had the right feeling that graphical user interfaces were already around and taking up speed. The future (that is the time we live in now) would belong to applications running on the main graphical user interface platforms at this time, being Microsoft Windows, the X Window System and macOS. Of course there were voices that argued that graphical user interfaces were only hampering productivity and real pros would always use the command line. That may sound a bit funny today, but I took it all in my heart.
When I arrived there, development had pretty much advanced in the compatibility layer named Star View, that allowed portable programming of both operating system functions and graphical user interfaces. There was, however, no application yet. Because I had worked on a C++/X Window System project on the ODA standard (ISO 8613, Open Document Architecture), I had some background on this and formed with some others the core of the Star Writer project team.
The offices of Star Lab at that time were at Heidenkampsweg, near Berliner Tor, in Hamburg in a quite modern building. I remember the adjacent gas station; many of us were heavy cigarette-smokers at that time, and I sometimes went there at night to get the next pack.
Dirk Bartels supervised the daily operations. He had a software company back in Berlin and …

Hi, I’m Marco, an Italian translator and Member of The Document Foundation. Twice a year I take part in an event in Pordenone to promote LibreOffice within the stand “Linux Arena” of the PNLUG Linux User Group. It’s inside a local fair, part of which is dedicated to technology, makers, electronics and so on.
For the event from April 25 – 27 we had a LibreOffice stand with a 32″ monitor, showing an Impress presentation about LibreOffice on a loop. At the stand I met different interested people – some of whom I already know since they visit the fair regularly, while others I saw for the first time.
There is always curiosity about LibreOffice, and this time I noticed an increasing demand about AI integration and related plugins. The LibreOffice coffee/beer mats were very much appreciated by visitors to the stand.
The Pordenone Linux User Group invited other associations to share the stand, so there were also:
The next edition of the event will be on 22 – 23 November.
Over the course of its 20-year history, the ODF standard has been adopted, or at least recommended, by numerous supranational bodies and several countries on almost every continent. However, this does not necessarily mean that the ODF standard is used in accordance with these decisions, which are often laws in their own right, as Microsoft’s substantial lobbying and misinformation campaigns aimed at protecting its revenue of around $25 billion generated by the proprietary OOXML format (DOCX, XLSX and PPTX) encourage the use of the latter. This is despite the fact that the disadvantages for national systems, communities of citizens and individuals are very easy to demonstrate: loss of control over content, interoperability problems and dependence on the commercial strategies of a single vendor.
The information in this post is based on my research into sources relating to the adoption or recommendations for the use of ODF. I began compiling this collection of documents around 2010 and continue to update it annually. Over the last twelve months, I have also used artificial intelligence in my research, which has helped me find some articles.
Unfortunately, formal adoption or recommendation of ODF does not guarantee its actual use in accordance with the law. For example, the latest version of Italy’s Digital Administration Code explicitly prohibits the use of OOXML because it is not a standard, yet this decision is largely ignored by public bodies.
SOVEREIGN BODIES
NATO requires all 28 member countries to use ODF as the standard format for document exchange.
UN and NGOs: UN organisations favour standard and open formats to ensure that all documents remain accessible and do not depend on expensive or restricted tools. This is why ODF is used for reports, policy drafts, and collaborative documentation between teams.
European Commission: has taken a strong stance in favour of open standards and promotes the use of formats such as ODF in documents through its open source software strategy. The European Parliament, the European Commission and the EUIPO (European Union Intellectual Property Office) have integrated LibreOffice and ODF into their internal workflows to ensure greater transparency and language neutrality.
EUROPE
Belgium: Since September 2007, all Belgian federal government departments have been required to accept and read ODF documents, and a memorandum has established ODF as the standard for the exchange of office documents within the federal public administration.
Denmark: From 1 April 2011, the Danish Parliament has mandated the use of ODF by state authorities for the exchange and archiving of documents, whereas previously agencies were only required to accept ODF documents. In recent weeks, articles have claimed that the Danish government will formally migrate to open-source software and, therefore, to ODF. We are, of course, seeking confirmation of this project.
Finland: The Ministry of Justice and other ministries have adopted ODF as the main document format.
France: The Référentiel Général d’Interopérabilité (RGI) recommends ODF as the preferred format for office documents in public administrations. Agencies are therefore encouraged to use ODF …

Susanne Mohn asked on the German-language user’s mailing list how to create a colour wheel with LibreOffice. It was not about the colours themselves, but about the geometry. How do you create a circle or ring with equally sized sectors?
Very different solutions were proposed. Susanne Mohn, Harald Berger and I (Regina Henschel) have created a page in the LibreOffice Wiki so that these do not remain hidden in a thread. Due to the development process, some sample files are in German, but the page itself is in English.
Colour wheels can be used to create “doughnut charts” of data. Have fun exploring!
The Document Foundation and LibreOffice support the international campaign @endof10 https://endof10.org/
The countdown has begun. On 14 October 2025, Microsoft will end support for Windows 10. This will leave millions of users and organisations with a difficult choice: should they upgrade to Windows 11, or completely rethink their work environment?
The good news? You don’t have to follow Microsoft’s upgrade path. There is a better option that puts control back in the hands of users, institutions, and public bodies: Linux and LibreOffice. Together, these two programmes offer a powerful, privacy-friendly and future-proof alternative to the Windows + Microsoft 365 ecosystem.
The real costs of switching to Windows 11
The move to Windows 11 isn’t just about security updates. It increases dependence on Microsoft through aggressive cloud integration, forcing users to adopt Microsoft accounts and services. It also leads to higher costs due to subscription and licensing models, and reduces control over how your computer works and how your data is managed. Furthermore, new hardware requirements will render millions of perfectly good PCs obsolete.
This is a turning point. It is not just a milestone in a product’s life cycle. It is a crossroads.
The new path: Linux + LibreOffice
These two programmes form the backbone of a free and open computing environment based on open standards. For individual users, public administrations, schools and businesses, this combination offers more than enough: it is mature and secure, and is already in use worldwide for mission-critical workloads. Furthermore, using open standards protects users against any attempts by software developers to control them.
Here’s what this alternative offers:
(This is part of The Document Foundation’s Annual Report for 2024 – we’ll post the full version here soon.)
Concerns about end user privacy in the digital world have grown significantly over the past two decades, with and increasing awareness of data collection, user tracking and online surveillance. Many proprietary applications, including office productivity tools, often collect vast amounts of user data, in most cases without clear user consent.
All this has been clearly documented by Shoshanna Zuboff in her book: The Age of Surveillance Capitalism, which is defined as a new economic strategy that uses the activities and experience of the individual as a free raw material for hidden commercial practices of extraction, prediction, profiling and selling.
In this context, open source software differs substantially because respect for the user and for privacy are part of the ethical principles that guide the development of all applications. And LibreOffice stands out as the only office suite – open source or not – that respects privacy. Unlike proprietary alternatives, LibreOffice is designed with privacy, transparency, and user control of content in mind. The software does not collect telemetry data by default, does not include intrusive tracking functions, and allows users to work completely offline.
The following is a list of LibreOffice features and settings which help ensure end-user privacy, making the software a preferred choice for individuals, businesses and government institutions that prioritise data security.
One of the most significant privacy benefits of LibreOffice is its lack of telemetry by default. Unlike proprietary office suites that constantly send usage data back to their developers, LibreOffice does not collect or send any personal data without the user’s consent.
LibreOffice offers an optional telemetry feature, but it is entirely opt-in and requires explicit user consent. The collected data will only be used to improve the functionality of the software and will never be shared with third parties.
Unlike cloud-based office suites such as Google Docs, Microsoft 365 or Apple iWork, LibreOffice is a fully offline suite.
For security-conscious organisations such as government agencies, law firms and healthcare providers, this offline capability ensures that sensitive documents never leave the internal network.
With LibreOffice 24.8 close to end of life, all users are invited to update their free office suite to the latest release
Berlin, 6 June 2025 – The Document Foundation is pleased to announce the release of LibreOffice 25.2.4, the fourth maintenance release of the LibreOffice 25.2 family for Windows (Intel, AMD and ARM), MacOS (Apple Silicon and Intel) and Linux, available for download at https://www.libreoffice.org/download [1].
With LibreOffice 24.8 approaching the end of life, this release – which includes dozens of fixes and enhancements that further improve the suite’s performance, reliability and interoperability – is ready for production environments. We invite all users to update their installation as soon as possible.
LibreOffice 25.2.4 is based on the LibreOffice Technology, which enables the development of desktop, mobile and cloud versions – either from TDF or from the ecosystem – that fully support the two ISO standards for document formats: the open ODF or Open Document Format (ODT, ODS and ODP) and the closed and proprietary Microsoft OOXML (DOCX, XLSX and PPTX).
Products based on the LibreOffice Technology are available for all major desktop operating systems (Windows, macOS, Linux and ChromeOS), mobile platforms (Android and iOS) and the cloud.
For enterprise-class deployments, TDF recommends a LibreOffice Enterprise optimized version from one of the ecosystem companies, with dedicated value-added features and other benefits such as SLAs and security patch backports for three to five years.
English manuals for LibreOffice 25.2 Write, Impress, Draw and Math are available for download at https://books.libreoffice.org/en/. End users can get first-level technical support from volunteers on the user mailing lists and the Ask LibreOffice website: https://ask.libreoffice.org.
Downloading LibreOffice
All available versions of LibreOffice for the desktop can be downloaded from the same website: https://www.libreoffice.org/download/.

At the beginning of May, we began a new Month of LibreOffice campaign, celebrating community contributions all across the project. We do these every six months – so how many people got sticker packs this time? Check it out…
This is a huge increase over the last campaign, in November, which had 301 winners. So that’s fantastic work, everyone! Hundreds of people, all across the globe, have helped out in our projects and communities. And those are just community contributions, not including the hundreds more from our ecosystem and certified developers!
We’re hugely thankful for the work – and, of course, everyone who’s listed on the wiki page can get a sticker pack, with the stickers shown above.
If you see your name (or username) on this page, get in touch! Email mike.saunders@documentfoundation.org with:
…and we’ll send you a bunch of stickers for your PC, laptop and other kit. (Note: your address will only be used to post the stickers, and will be deleted immediately afterwards.) If you contributed to the project in May but you’re not on the wiki page, please let us know what you did, so that we can add you!
And we have an extra bonus: ten contributors have also been selected at random to get an extra piece of merchandise – a LibreOffice hoodie, T-shirt, rucksack or snazzy glass mug. Here are the winners (names or usernames) – we’ll get in touch personally with the details:

Writer has some support for interdependent (or hierarchical) tracked changes: e.g. the case when you have a delete on top of an insert. While there were some working cases, handling of many combinations were missing. I started to make systematic improvements in this area in the recent past, this post gives you an overview what's done so far.
This work is primarily for Collabora Online, but the feature is available in desktop Writer as well.
DOCX files in Word can often have overlapping tracked changes: Writer tries to split these up to make sure there is only one tracked change under the cursor at the same time. Still, it's possible that you have a tracked change with multiple types: e.g. a delete on top of an insert.
The focus in on 3 combinations which appear in DOCX files a lot: "insert, then delete", "insert, then format" and "delete, then format".
This mostly affects the UI and import/export filters of ODT and DOCX.
Given an insert, then delete:
Interdependent tracked change: insert, then delete
Most operations worked nicely here, but in case your cursor was in the middle of AAA and you did a reject, followed by an undo, proper handling of that was missing, now implemented.
But then given an insert, then a format:
Interdependent tracked change: insert, then format
Then a handling of more actions were missing:
The combined implementation of these should give you a smooth feeling in case you're used to how Word works: if there is a format redline combined with an insert, then the operations act on the insert type, and format is only accepted/rejected when there is no insert "under" the format.
Similarly: it's a bit of an implementation detail that Writer splits redlines on DOCX import: so if you e.g. accept AAA then we combine that with BBB and CCC when it makes sense, so you need to click a lot less.
Finally, given a delete, then a format:
Interdependent tracked change: delete, then format
Then again handling of some actions were missing:
