Announcement of LibreOffice 25.8.4

Berlin, 18 December 2025 – LibreOffice 25.8.4, the fourth minor update to the free office suite developed by volunteers for personal productivity in office environments on Windows, MacOS and Linux, is now available from the download page.

With LibreOffice 25.2 reaching the end of life on 30 November, and the announcement of LibreOffice 26.2 scheduled for early February, this release is ready for production environments. It provides over 70 fixes which further improve the suite’s performance, reliability and interoperability. All LibreOffice users are encouraged to update their installations as soon as possible.

LibreOffice 25.8.4 is based on the highly robust LibreOffice technology platform, which supports the development of desktop, mobile, and cloud applications from both TDF and ecosystem companies. The platform supports both available document formats for full interoperability: the native, open standard ODF (Open Document Format, ODT, ODS and ODP) and the proprietary Microsoft OOXML (DOCX, XLSX and PPTX).

Products based on LibreOffice Technology are available for all desktop operating systems (Windows, macOS, Linux and Chrome OS), mobile platforms (Android and iOS), and the cloud.

For enterprise-class deployments, versions are available from ecosystem companies with added features and benefits, such as SLAs and security patch backports for three to five years (LibreOffice in business).

English manuals for the LibreOffice 25.8 family can be downloaded from the LibreOffice bookstore. End users can access initial technical support from volunteers via mailing lists and the Ask LibreOffice forum.

All available desktop versions of LibreOffice can be downloaded from the same download page. To improve interoperability with Microsoft 365, TDF recommends installing the Microsoft Aptos font from the specific download page.

LibreOffice enterprise and individual users can support The Document Foundation and the LibreOffice project by making a donation on the donations page.

The team is almost identical, with translations by Petr Kuběj, Zdeněk Crhonek and Radomír Strnad and technical support from Miloš Šrámek. Download it from the website. Thanks to everyone for the hard work, and if anyone would like to join the team, they are welcome to do so.

Excellent work everyone!

Videos from the Open Source Conference 2025 in Luxembourg

At the recent Open Source Conference 2025 in Luxembourg there were two talks about LibreOffice.

The first was Lessons learned from 13 years at The Document Foundation and LibreOffice, where Florian Effenberger, Executive Director of the foundation, talks about the legal setup of The Document Foundation and how its statutes enshrine values and ideals like openness, transparency and meritocracy.

Then there was Open Innovation and Open Source in Schleswig-Holstein – Practice for Europe, where Sven Thomsen, CIO of the German federal state of Schleswig-Holstein (which is moving to LibreOffice), outlined the state’s pioneering path toward digital sovereignty through Open Source and Open Innovation. The talk highlighted the risks of dependency on proprietary software—including lack of transparency, inflated costs, and reduced security.

Relaunching ODF Advocacy as ODF News

I decided to start the current campaign, with one blog post per week focusing on the different aspects of Open Document Format, to celebrate the 20th anniversary of the standardisation by OASIS, which happened in May 2005.

My hope was to raise the interest around ODF, which is the document format that every conscious user of office suites should adopt in order to maintain full control on his intellectual property (even if we are not professional writers or researchers, the content of our documents is our intellectual property, and we have the right to decide when, how and with whom we want to share it).

My articles were targeting LibreOffice users, as they have the privilege – over other office suite users – of creating documents (and I am not referring only to text, but also to spreadsheets and presentations or drawings) with the only program adopting ODF as native document format.

I wanted to strengthen their understanding of ODF, and explain in detail the enormous value of the open and standard document format they are using in comparison with the closed and proprietary Microsoft office document format, which is unfortunately the most used worldwide to maintain Microsoft lock in and reinforce Microsoft monopoly.

Software supporting OOXML – the technical name of the closed and proprietary Microsoft office document format – as their native document format are in fact strengthening Microsoft lock in just because in their paramount ignorance of the real situation – today, OOXML is the only lock in tool available to Microsoft – they protect Microsoft rather than protecting their users. In reality, they are enemies of their own users, as they use Microsoft handcuffs to prevent them to own and control their intellectual property.

Unfortunately, the absolute majority of office suite users are not aware of the issues – for their intellectual property – related to the closed and proprietary Microsoft office document format, and are just victim of the irresponsible choice about the native document format made by developers of OnlyOffice and WPS Office, and the likes.

Of course, given Microsoft monopoly on office suites, programs must support OOXML to their best, as LibreOffice does, to “steal” Microsoft stronghold on intellectual property, and give it back to legitimate owners, i.e. users of Microsoft office series suites, whatever the name, and of their accomplishes.

While I was trying to explain all this with my blog posts about ODF, something unexpected happened: several journalists picked up the contents of the articles and relaunched them on their media, showing that there is still hope for a sane attitude about document formats, rather than the current “comfortable” behaviour of choosing the most frequently used document format without even thinking to the consequences of the evil strategy associated to it.

Based on this unexpected – and extremely positive – outcome, I have decided to revive the ODF Advocacy project (which was killed twice in the past) by launching ODF News (https://www.odf.news), where I will write about ODF and publish ODF supporting documents.

ODF News will go live in January 2026, to prepare for the 20th anniversary of ODF being approved as ISO/IEC 26300.
