Matrix Live 🎙

Dept of Spec 📜

TravisR says

Hello everyone! For this week's spec update you get me, Travis, instead of anoa (sorry). The heart of Matrix is the specification, modified by Matrix Spec Change (MSC) proposals - learn more at

Be sure to read the Spec Core Team (SCT) section in today's update for some exciting news about Matrix though - this has a good chance of affecting how the MSC process works in the future.

Spec Core Team

The SCT has been powering through MSCs for the second week in a row, using a new internal process to encourage activity and hopefully keep momentum going. If there's an MSC you think should be on the agenda, please visit the and raise it for consideration 🙂

We've also been at IETF 114 to talk about MIMI - an initiative to define a standard for messaging interoperability inspired by the DMA. Matrix appears to fit perfectly into this use-case, so we've been talking with various folks involved to ensure Matrix is on the radar, including preparing our own Internet-Draft to demonstrate how it could work. MIMI is not currently a working group within the IETF, but the expectation is that it will be soon - we look forward to this happening, and are eager to contribute to the process here - or proposing Matrix itself to IETF as an initiative in its own right.

Watch this space for updates, or visit to ask questions 🙂

Random MSC of the Week

The random MSC of the week is... MSC3554: Extensible Events - Translatable Text!

This MSC covers an Extensible Events (MSC1767) schema definition for translatable text! This would allow a client to send a message in multiple languages, with the receiver able to choose which language they're prefer to see the message in (ideally falling back to a default or machine translation if their preferred language was not available).

Like other MSCs that rely on Extensible Events, MSC1767 will need to land before this MSC can. But until then, it's great to see all of the wonderful things this feature will allow Matrix to do!

Dept of Servers 🏢

Synapse (website)

Synapse is a Matrix homeserver implementation developed by the core team

Shay says

Greetings! We have been hard at work on Synapse this week. Work on faster room joins continues. In addition, Synapse 1.64.0rc2 was released. Notable features include:

  • support for room version 10
  • per-room rate limiting for room joins
  • support for Implicit TLS for sending emails and much more, as well as a number of bugfixes, improvements to the documentation, and other changes to make Synapse leaner, faster, and generally more awesome.

Construct Server

Jason Volk reports

This week The Construct server runs on Alpine Linux using freshly cut docker images building on the 0.7 release announced last week. A few images are available for preview while a more complete matrix is filled out. I am proud to announce to TWIM that Construct offers the most compact docker image for a Matrix server at just under 15 MiB; the only caveat is that media thumbnailing won't be available.

There's still a lot of room for optimization and docker experts to critique! Feel free to join the discussion at and check out today!

Dept of Clients 📱

Element Web/Desktop (website)

Secure and independent communication, connected via Matrix. Come talk with us in!

Danielle announces

  • It’s holiday season but that won’t slow us down! We’ve been hard at work fixing defects and improving features.
  • Our recently released new search experience is continuing to be improved. This week we’ve added more accessibility, so it can be helpful to all.
  • We’ve completely finished the migration of our tests.
  • There’s a new “use case” screen for users who sign up, it asks folks who they'll talk to the most on Element and, in the future, that will help us to tailor the experience.

In labs (you can enable labs features in settings on or on Nightly):

  • Video rooms continue to improve. Check it out!

Element iOS (website)

Secure and independent communication for iOS, connected via Matrix. Come talk with us in!

Ștefan reports

  • It’s an exciting week for both our mobile teams as we’re ready to release our new authentication flow! If you’ve been reading TWIM for a while you’ll know that we’ve been working hard, across all Element teams, to improve our onboarding experience. Part of this work on iOS was a new Create Account flow.
    • We’re rolling the changes out slowly, so don’t panic if you don’t see the new experience yet!
  • In even more exciting news, our test coverage has increased with a big bump. We’ve gone from 12% to 51%!
  • We’ve also continued to make updates and improvements to our location sharing feature.
  • On the ElementX front we have our first proof of concept for sliding sync (sync v3) working and we’ve almost finished setting up snapshot and integration testing. We also have Rust logs, a new authentication service and performance tests incoming.
  • Finally, the account deactivation button has had a change of copy - this keeps us inline with Apple guidelines around deleting and deactivating accounts.

Element Android (website)

Secure and independent communication for Android, connected via Matrix. Come talk with us in!

Danielle says

  • Our new Nightly releases are now available and allowing us to catch any bugs or regressions even faster - exciting!

  • It will soon be easier than ever to create an account on Element, so if you’ve been waiting for an update before you recommend us to others, it’s nearly time! We’ll be rolling these changes out slowly over the next week or so.

    • Alongside the new create account flow will be an updated sign in and reset password experience. Check it out and let us know what you think.
  • Also in this release we’ve added a “match system settings” to the Font size screen.

Dept of SDKs and Frameworks 🧰

Trixnity (website)

Multiplatform Kotlin SDK for Matrix

Benedict says

Trixnity 2.2.0 has been released.

  • Mac builds are enabled, which means, that olm is bundled into macOS and iOS builds too. So no need to build olm yourself anymore.
  • trixnity-crypto has been introduced, which contains the matrix e2e-encryption stuff and was previously located in trixnity-client. The relocation allows you to possibly use this in e. g. appservices. Key trust level calculation, key backup, key verification will be moved into it too.
  • client: basic event relation support has been added to be prepared for the next matrix spec
  • client: added server discovery
  • updated to kotlin 1.7
  • some bug fixes

matrix-rust-sdk (website)

Matrix Client-Server SDK for Rust

ben reports

It's been a week of quite, constant progress on many fronts, most not that visible to the outside observer. For once, the progress on integration sliding sync into element-x for iOS has taken up speed, with many smaller bug fixes and additional features exposed through the FFI being added and performance optimisations. After the internal jack-in testing tool, this is the first actual trial of sliding sync for rust (and after the js-implementation, only the second client to actually use sliding sync overall)—and it has been tremendous. Latest tests put the loading time to first view on the first 20-ish rooms at a 150ms range 🎉.

More visible to the keen observers of the repository has been that we've updated the event_handler API to allow removing existing handlers, an important step towards implementing completion guaranteeing API calls, and that we've support for custom encrypted events now.

matrix-docker-ansible-deploy (website)

Matrix server setup using Ansible and Docker

Slavi reports

Thanks to MdotAmaan's efforts, matrix-docker-ansible-deploy now supports bridging to Discord via the mautrix-discord bridge. See our Setting up Mautrix Discord bridging documentation page for getting started.

Note: this is a new Discord bridge. The playbook still retains Discord bridging via matrix-appservice-discord and mx-puppet-discord. You're free too use the bridge that serves you better, or even all three of them (for different users and use-cases).

Slavi reports

matrix-docker-ansible-deploy now supports bridging to Kakaotalk via matrix-appservice-kakaotalk - a bridge based on node-kakao (now unmaintained) and some mautrix-facebook code. Thanks to hnarjis for helping us add support for this!

See our Setting up Appservice Kakaotalk bridging documentation to get started.

Matrix Summit schedule

Yan says

By the end of last week we received a bunch of proposal for talks and workshops for the conference. It were all together 32 proposals and we accepted almost all of them.

We released already multiple versions of our schedule. The current version is 0.5 html json

There is even some space left for late comers. In case you decide spontaneously to come and want to talk let us know, we will find a way.


You now get tickets for the summit for the fantastic price of 0 euro. We like to know in advance how many people will come. If you have already a ticket and can’t come please let us know. So we can give them to people on the waiting list.

Sharing is caring

If you'd rather listen to Yan and me talking about the Matrix Summit and its schedule, we recorded a podcast episode for you to get informed on the go. (German)

Dept of Interesting Projects 🛰️

Effektio (website)

ben reports

The team of effektio, the mobile-first organizing app build on matrix, is happy to announce the new website. Aside from the revamped team section, we are particularly excited about the new product progress page, as the questions "what are you building exactly, and how far are you with the progress" are commonplace. With the product page we hope to provide more clarity what we mean, in actual features, when we say "organize yourself, your friends, family, clubs and all other communities from the palm of your hand". Each feature also links right into the specific section of the Github project, so you can get an unobstructed view of the actual progress happening—and contribute, if you like.

Dept of Ping 🏓
