LibreOffice 3.5.1 provides additional security and stability

Berlin, March 15, 2012 – The Document Foundation announces LibreOffice 3.5.1, the second version of the 3.5 family, targeting private individuals and enterprises. LibreOffice 3.5.1 fixes the majority of the most-important bugs identified by users and is expected to be appealing for most enterprises. TDF encourages large organizations to deploy LibreOffice in conjunction with a support partner, who can assess specific requirements, help manage migration and provide bespoke fixes for identified issues. Purchasing LibreOffice support from a TDF partner provides enterprises with an indirect means to contribute financially to the project, to fund software development, to improve the stability and accelerate the growth. “During the last month, the number of TDF hackers has overtaken the threshold of 400 code developers, with a large majority of independent volunteers and several companies paying full time hackers. In any case, the project is independent, as none of these companies employs more than 7% of the developers”, affirms Italo Vignoli, member of the Board of Directors. “Since September 2010, a monthly average of 20 new hackers has joined the project, attracted by the copyleft license, the lack of copyright assignment and a welcoming environment”. LibreOffice 3.5.1 is available for immediate download from the following

The Document Foundation publishes details of LibreOffice 3.4.3 security fixes

The Internet, October 4, 2011 – The Document Foundation (TDF) publishes some details of the security fixes included with the recently released LibreOffice 3.4.3, and included in the older 3.3.4 version. Following industry best practice, details of security fixes are withheld until users have been given time to migrate to the new version. RedHat security researcher Huzaifa Sidhpurwala identified a memory corruption vulnerability in the code responsible for loading Microsoft Word documents in LibreOffice. This flaw could have been used for nefarious purposes, such as installing viruses, through a specially-crafted file. The corresponding vulnerability description is CVE-2011-2713,”Out-of-bounds property read in binary .doc filter”. LibreOffice 3.4.3 also includes various improvements to the loading of Windows Metafile (.wmf) and Windows Enhanced Metafile (.emf) image formats that were found through fuzz testing. LibreOffice developers have developed some additional security patches and fixes. These are part of a general set of development improvements which are reflected in the overall quality and stability of the software. Most LibreOffice 3.4.3 security fixes have been developed by Caolan McNamara of RedHat and Marc-André Laverdière of Tata Consultancy Services. “Working on fuzzing LibreOffice import filters has been a great experience, and I am glad I could contribute in

LibreOffice 26.8.1 improves compatibility and text import

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

How LibreOffice is funded

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

LibreOffice 26.8 brings professional typography, deeper support for the world’s writing systems, and no artificial intelligence

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.

Why Digital Sovereignty Requires an Open Document Platform — and What That Actually Means

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
