Tell us a bit about yourself!

I’m a software engineer from Hungary. I’ve been working in software engineering for more than a decade, with a background in both computer science and psychology.

I’ve been a long-time contributor to LibreOffice, mainly working on Writer and Impress, and I’ve also contributed to Collabora Online as part of the Collabora team. Throughout my career, I’ve always placed a strong emphasis on the quality of my work and on building things properly, even when that sometimes meant pushing back against management priorities.

Outside of software development, my current project is setting up my own camper van, intending to eventually explore Europe with it. I’m looking forward to combining some travel with my work on open source projects.

What’s your new role at TDF, and what will you be working on?

My new role at The Document Foundation is to participate in building LibreOffice Online. We are basically trying to create a Google Drive or Google Docs-like solution on top of LibreOffice as a document editor, and bring LibreOffice into the cloud. Currently, I’m doing some research into existing cloud infrastructures to identify best practices and avoid the same problems that other projects have encountered during the lifetime of their cloud implementations.

More details about the development strategy can be found in this post.

How can users of LibreOffice help you in this work?

Well, we’re still in the design phase, so there isn’t much room for involvement at this point. At some point, once we have the initial versions LibreOffice Online, feedback would be very much appreciated. We will post updates here on the blog.

Following the first batch, we’ve added 15 more videos to the playlist, bringing the total up to 26! There are more still to come, along with PeerTube versions of course – but for now, enjoy browsing the playlist:

LibreOffice is a volunteer-driven, community open source project, backed by a non-profit entity, The Document Foundation. The vast majority of the foundation’s income is from community support, and we’re happy to announce that FLOSS/fund has made a very generous contribution of USD $100,000 to support the LibreOffice project and community.

FLOSS/fund is from Zerodha, a financial technology company and India’s largest stock broker. It is built heavily on FLOSS (free, libre and open source software) and gives up to USD $1 million to support projects around the world.

Kailash Nadh from FLOSS/fund (and CTO at Zerodha) says:

LibreOffice is one of the most consequential and impactful FOSS projects in the world. We also strongly believe that it has played an important role in enabling adoption of the Linux desktop among regular users. This belief in fact comes from our personal experience of transitioning over 1000 non-technical employees at our organisation to Linux over decade ago.

Many thanks to FLOSS/fund for their support. This helps us to improve our infrastructure, pay developers to work on the software, and organise events to share knowledge. Thank you!

The Salvadoran Lutheran University (ULS) and the Latin American LibreOffice Project community announce the seventh edition of the LibreOffice Latin American Conference.

Previous editions of the LibreOffice Latin American Conference have been held in person in Asunción (2019), Brasília (2022), Mexico City (2023), Montevideo (2024), and Havana (2025). The 2026 edition will bring the event to El Salvador for the first time, further expanding the reach of the LibreOffice community in Latin America.

ULS, the event’s host, has a long history of involvement with Free Software, most notably through the biannual FESOL (Free Software Educational Fair)—an event held for over 20 years that showcases dozens of projects developed by Computer Science students in areas such as web systems, databases, robotics, and video games, among others.

The conference will take place on November 27 and 28, 2026, with the aim of bringing together users and contributors to share knowledge and experiences related to LibreOffice.

Guest speakers from Mexico, Spain, Brazil, France, and Taiwan will present topics ranging from tutorials on using the applications to ways of collaborating with the project. The schedule will be announced soon on the official event website:

FrOSCon is an annual conference dedicated to Free and Open Source Software (FOSS), held in Sankt Augustin (near Bonn), Germany. And this year, the LibreOffice community was there! We hosted a booth featuring information flyers and merchandise, including stickers, pens, coasters, and more.

We engaged in many substantive conversations at the booth about LibreOffice as a project and its specific features. We also discussed TDF’s development plans for web and mobile platforms and encouraged people to get involved in these areas.

Many visitors stopped by saying, “Of course we use LibreOffice” – often contrasting it with Microsoft Word, which is the “standard” or widely used option in corporate environments. We also frequently heard comments like, “I’ve/we’ve already donated.” Clearly, there is a widespread willingness to contribute financially to software that is both high-quality and genuinely free.

Visitors were happy to take home coasters or small stickers. LibreOffice supporters often like to place these items where Microsoft-oriented users can be found.

Alongside the project booth, Andreas Mantke gave a presentation in German titled “Where is LibreOffice Headed?” (Wohin führt der Weg von LibreOffice?), in which he discussed the project’s planned development ideas for web and mobile and answered questions from the audience.

We look forward to being at more events in the coming months!

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 …

Last week we had the LibreOffice Conference 2026 in Pordenone, northern Italy. It was a great event – thanks to the local organising team!

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 …

A few weeks ago, Linux New Media released an updated version of its “LibreOffice Expert” magazine, which contains tutorials, tips and tricks about the office suite. And some articles were contributed by members of the LibreOffice community! The magazines come with DVDs that include LibreOffice for Linux, Windows and macOS, alongside extra templates, extensions, videos and guidebooks.

We have some copies to give away, for schools, universities, libraries and local communities. Ideally, we’d like to get these magazines out to places where internet connections aren’t always available – so that the users can really benefit from the DVDs.

So, if you can help us to distribute these magazines, drop us a line! Please note that we have 50 copies in total and can therefore only send a maximum of five copies to any one place, to make sure many communities get a chance. When you contact us, please include this information (any requests without information cannot be fulfilled and will be ignored):

1. What you want to do with the magazines
2. How many you want (1 – maximum 5 copies)
3. The address to which we should post them

Include all of that that information in an email to us with subject line “LibreOffice Expert for communities” and let’s see what we can do!

(Note: if you want to buy the magazine directly from the publisher, you can do so here.)

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 …
