Matrix Live

Dept of Status of Matrix 🌡️

Josh Simmons says

Important deadline: next week, the week of April 15th, is the last week to become a member before the Governing Board nomination period! You must be a member, or have your application in and approved, by the end of day on April 19th (AOE time) in order to be eligible to nominate. Stay tuned for a blog post all about that on Monday ✨

This week we’re proud to welcome GNOME and KDE e.V. as our second and third Associate Members, and there are more applications in the pipeline that we’re reviewing!

Dept of Spec 📜

Andrew Morgan (anoa) reports

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

MSC Status

New MSCs:

MSCs in Final Comment Period:

Accepted MSCs:

  • No MSCs were accepted this week.

Closed MSCs:

Spec Updates

A few MSCs working their way through the process this week, alongside a few more in FCP! As mentioned previously, Trust & Safety is a big focus for the MSC process this week, as we invest some time in keeping Matrix a nice place to be.

Outside of that though, I'm particularly excited to see support for formatting of math landing in the spec (MSC2919). That's been a long-time coming, and will be very helpful to math or math-adjacent communities using matrix (machine learning, anyone?).

Dept of Servers 🏢

Synapse (website)

Synapse is a Matrix homeserver implementation developed by the core team

Andrew Morgan (anoa) says

This week Element released Synapse v1.105.0rc1, a release candidate for the next version of Synapse. Of note are stabilisation for a few previous-unstable features such as /relations recursion, as well as moving /pushrules endpoints off workers for better scalability.

There was a small round of bugfixing as well that went into this pre-release, but there are likely more lurking! If you're able to, please test this release candidate. The full release of Synapse v1.105 is expected early next week. Thanks!

Dendrite (website)

Second generation Matrix homeserver

Till reports

Just going to copy and paste this from :

Dendrite 0.13.7 has been released!


  • Fixed an issue where the displayname/avatar of an invited user was replaced with the inviter's details

  • Improved server startup performance by avoiding unnecessary room ACL queries

    • This change reduces memory footprint as it caches ACL regex patterns once instead of for each room
    • Unnecessary Relay related queries have been removed. Note: To use relays, you now need to explicitly enable them using the federation_api.enable_relays config
  • Fixed space summaries over federation

  • Improved usage of external NATS JetStream by reusing existing connections instead of opening new ones unnecessarily


  • Modernized Appservices (contributed by tulir)
  • Added event reporting with Synapse Admin endpoints for querying them
  • Updated dependencies

Dept of Clients 📱

Dept of SDKs and Frameworks 🧰

Elm SDK beta 3.0.0

Bram says

After having written a few short pieces, multiple discussions in and reaching out to various members of the community, the Elm SDK has finally a new update. And it's a major one!

  1. There is finally a functional Timeline type that is an immutable representation of the Matrix timeline. This took months to complete.
  2. A new Matrix.User module has been exposed.
  3. The sender field in Event type now returns a User instead of a String.

Surprisingly, it is the last change that makes the update major, as that's the one that breaks backwards compatibility. I spent months working on something that would not have been more than a patch update on its own. 😓

Nevertheless, it's out now on the public Elm registry! If you're not an Elm programmer, please give me feedback on the new User documentation page as I aim for it to be simple to understand for starting Elm programmers who know nothing about Matrix. Your feedback would be very welcome in the room. ❤️ Thanks!

Dept of Interesting Projects 🛰️


ben reports

This week's update has several updates and fixes since the last time we posted about it here. Among other things, we have revamped the UI flow for Calendar Events, making it a much smoother experience, added participants icons to it, as well as Attachments and Comments. On the Chat side you can now bookmark and filter by DMs and bookmarks, and with the new App User Drawer you can directly switch to an existing or create a new DM, block, kick and kick-ban the user from the room. Next to several fixes we've also re-introduced localization and language switching support with a tight integration into weblate for easy web-based community-driven translations.

Of course this release again comes with a "What's new & AMA" Zoom sessions next week, Tuesday 15th 9:30GMT anyone is invited to join. Zoom Link here, iCal of the Event here

Matrix Dart SDK (website)

Matrix SDK written in pure Dart.

td reports

weekend project: came by yesterday and thought it would be cool if we MatrixRTC calls could use the Cloudflare SFU as an alternative to the current Livekit SFU.

and mwhahah- there's a implementation now, this also gave td some fancy ideas on how to handle different SFUs easily in the spec and not have clients break stuff because of different client library implementations. Apart from that, just having a huge global infrastructure like Cloudflare providing you a SFU just sounds cool! It even does stuff like cascading and choosing the closest SFU based on BGP internally so users are not limited to just one SFU and have the lowest latency. (see blog post linked above for the technical details)

The Cloudflare SFU unfortunately is neither open source nor free afaik and the blog mentions:

To kick off its open beta phase, Calls is available at no cost for a limited time. Starting May 15, 2024, customers will receive the first terabyte each month for free, with any usage beyond that charged at $0.05 per real-time gigabyte. Beta customers will be provided at least 30 days to upgrade from the free beta to a paid subscription. Additionally, there are no charges for in-bound traffic to Cloudflare.

so don't see any clients using this anytime soon, but was fun and just proves how easy and modular the new MatrixRTC structure is :D
