Spec Updates

Matrix v1.7 has been given a release date of May 25th, right before the next TWIM! Expect a blog post with all the details on the day.

Leading up to the release we've seen a number of great spec PRs appearing and being merged! Thank you to everyone for writing them (saving the SCT some time!) and to other reviewing on commenting. It's a huge help and the spec feels like it's chugging along at a blistering pace!

Random MSC of the Week

The random MSC of the week is... MSC2213: Rejoinability of private/invite-only rooms!

This MSC adds the ability for users who have previously joined a room to rejoin again. Typically this isn't desired in a public room setting, but it does specifically make sense in the case of a DM that you've left and want to return to without the other user needing to invite you. This case has specific implications for cases where there could be only ever one room between two users. Being able to rejoin it if the other user has disappeared is key!

Outside of the DM use case, this functionality can mostly already be achieved by using restricted rooms, where users of a given space/another room can always join your room. However, it would be nice to have the flexibility of allowing certain users to rejoin a room without needing another room to serve as proof of membership.

Is this something you're interested in? Do you have additional use cases? Feel free to check out the MSC and comment with your thoughts!

Fractal (website)

Matrix messaging app for GNOME written in Rust.

Kévin Commaille says

Fractal 5.beta1 is out!

Fractal 5.beta1 is the first beta release since the rewrite of Fractal to take advantage of GTK 4 and the Matrix Rust SDK. It is the result of over two years of work.

New features since Fractal 5.alpha1:

  • Joining room by ID, by alias or with a Matrix URI
  • Creation of direct chats
  • Sending and displaying read receipts, read markers and typing notifications
  • Notifications on new messages
  • Highlight messages with mentions
  • Added media file history viewers in the room details, thanks to our GSoC intern Marco Melorio
  • Displaying the other user's avatar as a room avatar for direct chats

Of course, there are a also a lot of less visible changes, fixes and translations thanks to all our contributors, and our upstream projects.

As the version implies, this is still considered beta stage and might trigger crashes or other bugs but overall should be pretty stable. It is available to install via Flathub Beta, see the instructions in our README.

The GNOME 44 runtime used by the beta version Flatpak was shipped with a GTK version that has a regression which messes with room order in the sidebar: some rooms can appear twice and some rooms are missing. This is a known issue so there is no need to report it, there is nothing for us to do but wait until the fix is backported and shipped in an update of the GNOME runtime. In the meantime, the nightly version is unaffected by that.

A list of blocking issues for the release of version 5 can be found in the Fractal 5 milestone on GitLab. All contributions are welcome !

Ement.el (website)

Matrix client for Emacs

alphapapa says

Ement.el, a Matrix client for the GNU Emacs Lisp machine and text editor, has been released at version 0.9. Changes since the last release include:


  • Option ement-room-timestamp-header-align controls how timestamp headers are aligned in room buffers.
  • Option ement-room-view-hook runs functions when ement-room-view is called. (By default, it refreshes the room list buffer.)
  • In the room list, middle-clicking a room which has a buffer closes its buffer.
  • Basic support for video events. (Thanks to Arto Jantunen.)


  • Using new option ement-room-timestamp-header-align, timestamp headers default to right-aligned. (With default settings, this keeps them near message timestamps and makes for a cleaner appearance.)


  • Recognition of certain MXID or displayname forms in outgoing messages when linkifying (aka "pilling") them.
  • Unreadable room avatar images no longer cause errors. (Fixes #147. Thanks to @jgarte for reporting.)
  • Don't error in ~ement-room-list~ when no rooms are joined. (Fixes #123. Thanks to @Kabouik and Omar Antolín Camarena for reporting.)
  • Enable member/room completion in compose buffers. (Fixes #115. Thanks to Thanks to Justus Piater and Caleb Chase for reporting.)

Dept of SDKs and Frameworks 🧰

Elm SDK (website)

Bram reports

Sometimes, development isn't about writing code, it's about looking ahead and planning! In the past three weeks, I've tried to figure out how filters work combined with endpoints like /sync, /messages and /context - and it turns out I couldn't find any straight answers!

So I wrote a whitepaper in the Elm SDK repository on the inconsistencies and where the spec is unclear (to me, at least). I hope you're willing to look into it as I might open up an MSC soon where I request to be more specific about filters and the endpoints.

Read the whitepaper here, and please give me your feedback and/or corrections!

matrix-scala (website)

cheb reports

I've developed a rudimentary Matrix-Library for Scala for akka, for distributed async systems. The underlying code is actually automatically generated from the specification, with strong typing, automatic JSON (de-) serializiation and a rudimentary client provided. It features the entirety of the client-server API. This is achieved via a custom code-generator. This library provides just enough stuff to easily build a fully fletched client. A more high-level client is in development right now. Encryption will be hard, but will hopefully be implemented via JNI in the foreseeable future.

This is part of Germany's effort to move hospitals messaging systems to the Matrix protocol.

In case you want to check it out: A prebuilt is also provided

Trixnity (website)

Multiplatform Kotlin SDK for Matrix

Benedict announces

Trixnity got its first big external contribution in version v3.6.2!


  • added support for Android room database. Thanks to Jon Poulton!


  • allow parallel use of Okio media store

Dept of Bots 🤖

Trinity (website)

bnjbvr reports

Matrix bots in Rust and WebAssembly. If you're interested to follow the project, feel free to join or get the code on Github.

Since last time, we've upgraded to the latest version of wasmtime, wit-bindgen and cargo-component, and even found a bug in the toolchain! Thanks to the Bytecode Alliance folks for helping with a workaround.

We've also converted all the bot commands so they make use of the simpler libcommand API, and thanks to that, we could add support for emoji reactions easily. Now the bot will report success by adding 👌 annotation to the (human) request.

The bot will also report its presence as disconnected as soon as the program exits (and automatically mark itself connected when it gets back, but that part is thanks to the Rust SDK 💜).

Dept of Events and Talks 🗣️

Beepberry (website)

Eric Migicovsky announces

I announced a little side project yesterday: Beepberry - a portable e-paper computer for hackers, designed for chatting on Beeper (universal messaging app built on top of Matrix). My day job is running Beeper, but I will always have a soft spot for building hardware (I was the founder of Pebble).

I wanted to create a ‘weekend’ device that would let me stay in touch with friends and family, without the distractions of a full smartphone. I imagined a tiny, hackable e-paper screen with a physical keyboard, powered by a Raspberry Pi, that I could use to chat around my home…and do pretty much nothing else.

Before Matrix, the idea probably would not have gone anywhere. Most chat apps do not have an API, making it practically impossible to hack something like this together.

I partnered with sqmfi and they’re starting to take pre-orders at for the first batch. It’s $79 (or $99 including a Pi Zero). Specs: Sharp Memory LCD (same display tech as in Pebble!), Pi Zero (BT/WIFI), physical keyboard, 2000mAh lipo.

On top of being an amazing chat device, it’s basically an e-paper Cyberdeck that fits in your pocket. It’s a ton of fun to hack on. Keep in mind - THIS IS NOT A REAL FINISHED PRODUCT. It’s basically a devkit.

Here's what it looks like running a slightly customized version of gomuks:

NeoBoard (website)

Dominik Henneke reports

We are pleased to announce the NeoBoard — an open-source collaborative whiteboard widget for Matrix! The NeoBoard is an ideal tool for creating and sharing content, conducting presentations, and collaborating with colleagues or friends. All data is stored as Matrix events within the Matrix room, leveraging Matrix's native end-to-end encryption, decentralization, and data privacy features.

The widget uses CRDT documents (conflict-free replicated data type) and WebRTC to provide a seamless and fast editing experience. It is used in the German public sector and is now available to anyone looking for a powerful and secure way to collaborate.

The NeoBoard is the latest widget from Nordeck, which we have been developing behind the scenes in the past months, and we're excited to finally share it with the Matrix community. If you have any questions, reach out to us at

That's all I know

See you next week, and be sure to stop by with your updates!
