🔗The Matrix.org Security team publishes analysis of reported vodozemac issues
Following a public disclosure discussing potential cryptographic issues in vodozemac, the Matrix.org Security team published a technical analysis addressing the claims and their impact.
What a year again at FOSDEM! The community met at our Hackathon on Friday and worked on fancy ideas. We talked to thousands of people at our booth, and hosted the Decentralised Communication Devroom on Sunday. But Matrix was truly everywhere at FOSDEM.
HarHarLinks announces
We're excited that by this time next week, a lot of us will have gathered in Brussels for FOSDEM!
Check out our initial blog post for some photos of how this looked in 2025!
🔗Hackathon
We are looking forward to filling Hackerspace Brussels with beyond 100 Matrix hackers who signed up! We start at 9:00 in the morning and will finish the day with a round of lightning presentations at 17:00. Watch the banner on matrix.org and join the chat below for possible live stream announcements! 👀
This hackathon is a friendly place for Matrix newcomers just as well as veterans who will offer their mentorship. If you are interested in sponsoring lunch, dinner, livestream, or prizes, please reach out. Learn more on the blog and join us in #fosdem-2026-hackathon:matrix.org to stay informed!
🔗Booth
Booths all over the campus buildings allow a great diversity of projects to present themselves, and this includes Matrix. Visit us in building AW!
The booth is staffed by volunteers, and few shifts remain available! You can self-register using our shift management platform to join the fun and meet other Matrixers! On top, booth staff will receive one of a kind Matrix-at-FOSDEM-2026 T-shirts!
Whether you join the team or not, we are always looking for projects to put on display! Please reach out to #events-wg:matrix.org or via email with your ideas: your project, demo, stickers, or more!
🔗Devroom
Devrooms at FOSDEM are themed tracks, and we are organising the Decentralised Communications devroom. You can find the schedule on FOSDEM's website.
The devroom is hosted by a stage host introducing the speakers and a video technician ensuring the right camera or slides are shown on stream and recording. If you are interested in joining the team in either position, please reach out to #events-wg:matrix.org or via email.

Only 2 weeks later we are back with a quick wrapup of recent activities on the website before the holidays.
- Jack S. has been supporting us greatly in shipping a million updates to all kinds of ecosystem projects as well as finding and fixing some smaller issues and contributions.
- We cleaned up the blog categories a bit, slowly working towards clearer definition of what goes where.
- salixh5 checked the status of and contributed an update to the LINE bridge during a Matrix Stammtisch.
- anoa updated our footer social media icons to include the Foundation's Bluesky profile.
- We have updated the homepage to fulfil the platinum membership perk.
- andybalaam contributed documentation on how to hide images by default using different Matrix clients via the T&S R&D WG.
- The T&S team announced policyserv, the SCT published Matrix v1.17, and the Events WG shared the latest news about the upcoming FOSDEM 2026.
- We greatly simplified the website contribution workflow by updating the PR template and introducing more automated checks via linters. More about that is on the horizon and looking for contributors!
- The effort to tag issues we are looking for help for continues. You can already find 30 to get involved with using the help wanted tag!
The website office hour is on holidays and will return in its regular slot on 8th January! In the meantime, you can still find us in the #matrix.org-website:matrix.org room and of course keep sending PRs! See you again at TWIM next year.
As we've previously announced, we are organising a Matrix Hackathon before FOSDEM and co-organising the Decentralised Communication Devroom, and we will have a Booth. We have updates for you!
You might have seen our earlier post about the Decentralised Communication Devroom we are coordinating. This is one of the exciting ways to come talk to us, but it's not the only one!
This year we're organising a hackathon before FOSDEM, we'll have a booth during FOSDEM itself, and we're coordinating the Decentralised Communication devroom!
