This Week in Matrix 2026-03-27

🔗Matrix Live S12E03 – How hard can it be?

🔗Dept of Status of Matrix 🌡️

Amandine reports

🥁 The Matrix.org Foundation has published its first Public Annual Report! 📊

This report gathers useful information for a very wide group of users, starting with the current community but also others who may not know Matrix very well. Overall, the goal is to remind everyone what the Foundation is and why it exists, share the progress in the last financial year, explain how our funds have been used, give an overview of our finances and eventually provide a preview of our plan for 2026.

You can find the blog here and the report itself here. We hope you will find it a useful read! ☕️

🔗Dept of Spec 📜

🔗Matrix 1.18

TravisR announces

We also had a spec release! Matrix 1.18 brings 16 MSCs to the protocol, with a major focus on Trust & Safety - read more about policy servers, invite blocking, and more from this week's blog!

Andrew Morgan (anoa) {he/him} announces

Here's your weekly spec update! The heart of Matrix is the specification - and this is modified by Matrix Spec Change (MSC) proposals. Learn more about how the process works at https://spec.matrix.org/proposals.

🔗MSC Status

New MSCs:

• MSC4440: Profile Biography via Global Profiles
• MSC4439: Encryption key URIs in /.well-known/matrix/support
• MSC4438: Message bookmarks via account data
• MSC4437: Endpoint to replace entire profile

MSCs in Final Comment Period:

• No MSCs are in FCP.

Accepted MSCs:

• MSC4287: Sharing key backup preference between clients

Closed MSCs:

• No MSCs were closed/rejected this week.

🔗Spec Updates

Just before writing this update, FCP merge was (re-) called on MSC2545: Image Packs, which is the bedrock for custom emoji and stickers in Matrix. The MSC will allow you to create and share packs of images, which can be used for custom emoji or sticker packs.

If you are the author of a client who implemented an earlier draft version of this MSC, now is a good time to have another look at the proposal and update your implementation accordingly!

🔗Dept of Working Groups 💪

Room Directory Working Group update

We've got two milestones to celebrate this week - we've received over 100 applications for the room directory to date, and we've just published our first batch of hobby rooms 🎉!

So, if you're looking to find fellow tea enthusiasts 🍵, birders or bird watchers 🐦️, plain text accounting enjoyers or the thrillseekers of Formula 1 🏎️, look no further than the matrix.org room directory.

We can always use more helpers to review applications, so if you want to join the working group, chat with us in #room-dir-wg-office:neko.dev. And if you want to see your room listed, check out https://matrix.org/homeserver/room-directory/

🔗Dept of Events and Talks 🗣️

andybalaam announces

This week's Linux Dev Time podcast was about Matrix:

In the wake of Discord’s recent announcement about age verification, Matrix recently came in for a lot of criticism by a lot of people who said it’s not a viable replacement. Andy works on Matrix for a living and Amolith is invested in the XMPP world so we get into secure messaging, trade-offs between security and user experience, federation, and more.

🔗Dept of Clients 📱

🔗Nexus Client (website)

Matrix client made with Flutter and a Gomuks backend.

QuadRadical (Ping) says

🔗What's new?

Hello TWIM! I posted last week, but a lot has happened since then! We also have a new contributor, zach (@zach:matrix.zachs.io), thanks!

• Fetch memberships after messages are rendered for almost instant room loads
• zach: Support for building to an Android APK
• zach: Build with goolm rather than libolm by default
• Add a nix package
• Add a Flatpak build using https://github.com/neobrain/nix2flatpak
• Add CI builds of Flatpak and APK, and soon a Windows EXE build at https://github.com/Henry-Hiles/nexus/actions.

🔗Coming soon...

The next few features on the To-do are:

• Windows EXE builds on CI
• Fix some controller refreshes that are causing weirdness with messages moving around
• Add support for sending media
• Showing messages that are currently sending

After these, and likely some bug fixes, I think it will be time for an alpha, so that should be done in the next few weeks!

🔗Get involved!

If you want to help with development or simply keep up with new features, join our Matrix room at #nexus:federated.nexus, or check out the Git repo at https://git.federated.nexus/Henry-Hiles/nexus!

🔗Tammy (website)

Multiplatform messenger built on top of Trixnity Messenger.

Benedict says

We've released a small update for Tammy today. This update includes a convenient message draft feature, letting you compose messages and schedule them to send later – even if you switch rooms or close the app. You can also now mark rooms as read directly from the room list. As always, we've included several bug fixes to improve the overall experience.

🔗Dept of SDKs and Frameworks 🧰

🔗Trixnity (website)

Multiplatform Kotlin SDK for developing Clients, Bots, Appservices and Servers.

Benedict reports

In the last two weeks Trixnity got a few updates.

🔗Draft Messages

We've added support for storing draft messages. Users can now compose a message (e.g., typing text) and send it later. This is implemented as a flag in the outbox to prevent immediate sending.

🔗First Steps with MatrixRTC

Thanks to a community contribution, we've added event models for MatrixRTC MSC4143. This is extensible, allowing for the type-safe addition of new MatrixRTC applications. We'll share more MatrixRTC-related changes soon.

🔗Room Upgrade Improvements

Trixnity has always supported transparent room upgrades, meaning developers don’t need to worry about linking upgraded rooms. We've further improved this by automatically joining new or old upgraded rooms when using Trixnity APIs.

🔗Bug Fixes

We’ve resolved two long-standing bugs related to sending outbox messages. Sending should now be reliable. We also fixed several other bugs.
