LibreOffice 26.8.1 improves compatibility and text import

Update: due to issues with download mirrors, the release is being delayed. Version 26.8.0 is once again offered on the download page of the LibreOffice website. Apologies for the inconvenience – you can check this page to see when the download mirrors are working again. Thank you.

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

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.

Today, we are celebrating sixteen years of LibreOffice’s independence and commitment to supporting free software, open standards and digital sovereignty

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.

Software Freedom Day 2026: What Freedoms Does LibreOffice Offer

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.

LibreOffice 26.8 and interoperability: preserving what cannot yet be read

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.

LibreOffice 26.8 and the languages for which nobody is paid

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.
