Thank you for a great 2023!

Thank You for Everything We Achieved Together in 2023 🤝

At the end of the year, we like to look back at what we have achieved as a team alongside our worldwide network of partners and the community. 2023 was a particularly significant year for us as we celebrated ten years of Collabora Productivity, adding another productive decade to our mission of bringing document editing and trillions of existing documents into the free world!



In March we held another successful COOL Days conference, this time in Cambridge, which brought together our team, partners and the community. We are looking forward to another great event in April 2024 – join us!

As well as our own events, our team also attended over ten locations to present talks, meet partners and share Collabora Online with the wider community. You can keep up to date with our adventures on our events page.

2023 saw many organisations and users throwing off their proprietary shackles, and embracing the freedom open-source solutions bring. In particular, we saw many educational institutions reconsidering their relationship with Microsoft 365 and Google Workspace amid privacy concerns, great strides being taken by local and national governments such as the openDesk project in Germany, and increasing numbers of private companies taking back control of their document storage and editing needs.

Collabora Online, Collabora Office and our mobile apps have all seen performance improvements and increased functionality. In July, we released the new major release of our flagship product Collabora Online 23.05, which included increased interoperability, performance boosts and a whole range of new features and accessibility improvements. Thank you for your support! Let’s take a deeper dive into what we have achieved together this year. 💜


Collabora Online 22.05 → 23.05

Our flagship product, Collabora Online saw marked improvements in 2023, introducing many exciting new features and a big focus on accessibility, working to bring the best digital experience we can to all our users, regardless of their abilities or challenges.

CODE: Developing a Rock-Solid Enterprise Version 💪

The latest major release of the Collabora Online Development Edition (CODE) 23.05 was released in June. CODE always appears in advance of the corresponding version of Collabora Online – the Development Edition contains all new features which are extensively tested before becoming available in the Enterprise version (COOL). An overview of CODE releases for 2023 can be found in the release notes but will mostly mirror those of Collabora Online. You can find the conversations about CODE on social media, by searching for the hashtag #cool_dev on Mastodon or Twitter.


Powerful New Features for Collabora Office on the Desktop 🖥️

August 2023 saw the latest major release of Collabora Office, our long term supported desktop Office Suite for Windows, macOS, and Linux. This release brought a number of powerful productivity features focusing on accessibility and improving user experience. The new features contain code that was contributed to LibreOffice 7.4, 7.5 and 7.6. Collabora Office for Windows is available through the Microsoft Store. The latest version for macOS can be bought from the App Store. We also appreciate those who help us test the latest features inside our unstable snapshots.

Our major release for mobile and tablet devices in September 2023 brought more of the functionality from Collabora Online into the pockets of our users, as well as improving the current user experience and making navigating on smaller screens easier. Now you can use dark mode, improved form controls in Writer, Sparklines, consistent dialogs and a better UX for users on smaller screened devices.


Events 🗓️

COOL Days 2023 took place in Cambridge, with more than 50 participants joining from our team, partners and the community. We presented 45 lightning talks showcasing our talented developers’ work across the year, held workshops and discussions with our partners about the importance of data protection in Europe, shared our development roadmap, and further discussed how to mutually support our sales and marketing efforts as part of our partnership. The community dived into a LibreOffice Hackfest and of course we had a great time socialising and team building around historic Cambridge.




As well as our own annual conference, our team attended events across Europe presenting talks, meeting partners and sharing Collabora Online, as well as presenting a keynote at the LibreOffice Conference for Latin America in Mexico.
