Matrix Live 🎙

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:

  • No MSCs are in FCP.

MSCs with proposed Final Comment Period:

Merged MSCs:

  • No MSCs were merged this week.

"Wowza, that's a lot of new MSCs!" I hear you say. This is actually a listing of the last 3 weeks, as it was pointed out to me that the last 3 editions of TWIM have not all features an MSC status update - which means some MSCs may not have necessary made it into the limelight.

As such, here's those from this past week, as well as the ones that were missed!

Spec Updates

It's that time of the year again - a new Spec release is on the horizon! Matrix v1.3 is expected to land sometime this month, and will include:

  • MSC3440 (threads) + related MSCs
  • MSC3787 (knock+restricted join rules)
  • MSC3604 (room version 10)
  • Any other MSCs which have so far been accepted, but not yet made it into the spec.

MSCs which land between now and v1.3 might get incorporated if easy enough, though chances are they'll slip to v1.4 (expected next quarter).

On top of that, the other bit of news is that the proposal-in-review label has now been removed from the matrix-spec-proposals repo and thus all MSCs. This doesn't mean your MSC is no longer in review! We simply found the label redundant along with the other labels in the process (it was attached to all MSCs which hadn't been accepted/merged yet, which means very little) and thus we decided to remove it to reduce noise.

Random MSC of the Week

The random MSC of the week is... MSC2881: Message Attachments!

This MSC has actually been potentially(?) superseded by MSC3382. In short, both look to provide a solution to the problem of attaching (multiple!) images to messages, such that clients can display an album of images in a single event in the timeline.

Check it out if you're interested in introducing such a feature!

Dept of Servers 🏢

Synapse (website)

Synapse is a Matrix homeserver implementation developed by the core team

Andrew Morgan (anoa) says

Synapse v1.58.0 was released this week! Check out the v1.58 blog post for the full scoop, but the highlights are:

  • Our Docker images and Debian packages are now built from a dependency lockfile courtesy of Poetry. Props to David for leading the charge on this multi-week epic.
  • An experimental implementation of MSC3383 has been contributed by @Bubu and @jcgruenhage at Famedly, which will help with proxying federation traffic, amongst other uses.
  • An experimental implementation of MSC2815 has been merged, which allows room moderators to view redact event content for the purposes of moderation. This was contributed by @tulir at Beeper.
  • Device list updates are now asynchronous thanks to Erik, leading to much faster login times for accounts in big rooms.
  • plus many other bug fixes and improvements!

We also released a v1.58.1 patch shortly afterwards to address an issue with the Debian packages on some configurations. Server admins not using the Debian packages do not need to install this patch release.

Otherwise, ongoing work from the core team continues with Sean and Rich working on faster room join performance, Olivier pushing forwards on testing Synapse with workers in Complement, while Erik has been tackling general performance work.

Dept of Bridges 🌉

matrix-hookshot (website)

A multi purpose multi platform bridge, formerly known as matrix-github

Half-Shot reports

Hey folks! We're announcing our 1.6.0 release for matrix-hookshot today. More features in this release: tadzik has gotten involved and given us support for RSS feeds in this release. You can check out how to get going with those in our hosted documentation.

The highlights this time around are:

  • Add RSS/Atom feed support (#315)
  • Add support for GitLab in the widgets configuration UI. (#320)
  • Send a notice when a GitLab merge request gets some review comments. (#314)
  • Add new !hookshot gitlab project command to configure project bridges in rooms. See the docs for instructions. (#321)
  • New hookshot_connection_event(_failed) metrics for tracking successful event handling. Reinstate matrix_* metrics which were previously not being recorded. (#312)

matrix-appservice-kakaotalk (website)

A Matrix-KakaoTalk puppeting bridge.

Fair announces

This week brings another round of big improvements & new features!

Features & fixes include:

  • Fixes to Docker support & the documentation for setting it up
  • Changes to the login flow
    • The bridge can now be configured to enforce a login flow that more closely matches the official KakaoTalk desktop client's, and to better warn you when a new login will kick out another one of your KT sessions. This will hopefully prevent the bridge from getting KT accounts banned!
  • Backfilling for KT->Matrix read receipts
  • Commands for adding/removing KakaoTalk friends
  • Commands to edit your KakaoTalk ID & mark it as shared or hidden
  • Matrix->KT DM creation, i.e. the ability to create a new DM with a KakaoTalk user from within Matrix
    • This might fail on the first attempt at creating a DM. If it does, try re-inviting the KakaoTalk puppet to the room.
  • Many stability & correctness improvements

With the combination of friends list curation & DM creation support, it should now be possible to connect with KT contacts entirely from Matrix! Simply add some friends, list them, and invite a listed friend to a 1:1 room!

matrix-appservice-irc (website)

Node.js IRC bridge for Matrix

Half-Shot announces

Hi folks, note that today (Wednesday) we released a high security update for the matrix-appservice-irc bridge. Please update to 0.34.0 as soon as you can.

Dept of Clients 📱

Thunderbird (website)

Thunderbird is a free open-source email, calendar & chat app.

freaktechnik reports

This week we released Thunderbird Beta 101.0b1. It includes a bunch of bug fixes for the Matrix implementation and shows reactions as system messages, so you know when someone gives you a 👍️.

Nheko (website)

Desktop client for Matrix using Qt and C++17.

Nico reports

Someone on Twitter complained that no chat client works like MSN anymore, where you could have separate windows for each chat. So for MSN compatibility we added that. (It is a bit experimental still, expect some stuff to not work or crash)

Bulbu also went through a lot of effort to add a second set of emoji shortcodes to Nheko. Those should be more familiar to people coming from other platforms or clients while the old shortcodes are available still as well. We also saw a lot of progress on the Finnish, Chinese, Indonesian and Russian translations, animated images should work properly in the image viewer again, buttons for opening the member list are now clearly marked with a people icon next to them. The memberlist is also now search- and sortable.

Anyway, have a look at how important multiple windows are:

Ement.el (website)

Matrix client for Emacs

alphapapa announces

Ement.el has received several updates since the last time it was mentioned in TWIM:


  • A new room list command, ement-taxy-room-list, shows rooms grouped "smartly" (and programmably). (It will be made the default soon; until then, call the command to use it.)
    • The new room list shows unread-notification/highlight counts, similar to Element.
  • Basic support for spaces:
    • Rooms (and spaces) can be added to and removed from spaces.
    • Rooms are listed under their spaces in ement-taxy-room-list.
  • Reactions can now be toggled off (i.e. redacted) by clicking them, like in Element.
  • Command ement-room-send-file allows uploading non-image files to rooms, and file messages are now displayed usefully, so the files can be downloaded or viewed.
  • Command ement-ignore-user ignores and unignores users.
  • Command ement-tag-room adds and removes favourite, low-priority, or custom tags on rooms.
  • Command ement-room-occur allows searching messages in a room buffer, similar to Emacs's occur command (i.e. it locally searches already-received messages).
  • Membership events are now coalesced by default, similar to Element (especially helpful in large public rooms, like bridged IRC rooms, where join/part spam can be overwhelming).
  • "In reply to" links in replies, as well as other links, can be activated in a room buffer to go to the linked message.
  • Mentions in outgoing messages are HTML-linkified (aka "pilled"), like Element.
  • Generated avatars for rooms that have none, similar to Element. (Only displayed in ement-taxy-room-list for now.)
  • Option ement-shr-use-fonts (disabled by default, which prevents HTML messages from being displayed in a different font).
  • Faces for favourite/low-priority rooms.
  • Redacted messages that are still known locally are now displayed with a strikethrough (after reconnecting, their content will be unknown).
  • When images are disabled, image messages are presented as clickable URLs, so they can still be viewed.
  • Some events, like membership events and images, are displayed alongside a vertical bar to help distinguish them from normal messages.
  • Even "hotter"-looking timestamps for rooms updated in the last hour.


  • Refactored notification system. Now easier to configure (see M-x customize-group RET ement-notify RET).


  • Improved error handling when looking up homeserver hostnames and .well-known URIs.
  • Improved error handling when processing malformed events.
  • "Elemental" display style (not used by many users, apparently).

Element Web/Desktop (website)

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

madlittlemods (Eric Eastwood) reports

In this months demos (also shown off at the top of the TWIM post), Eric showed off a proof of concept to anonymize your screenshots so you can easily include more context when submitting logs or bug reports without worrying where the bug occurred. The current concept will color block all of the text on the page to still maintain the structure of the app but completely hide the content itself.

This still has a ways to go before it's integrated in Element under the click of a button so if anyone wants to take over or give feedback, go comment on the issue, If you want to use the anonymization now, you can manually run the JavaScript snippet from the issue in the browser devtools.

This mode could even be further extended further to include event_id labels in the corner of each message to easily correlate the logs to the screenshot.

Happy screenshotting!

kittykat reports

Populus Viewer (website)

A Social Annotation Tool Powered by Matrix

gleachkr reports

Over the last two weeks, the theme in populus-viewer development has been permissions:

  1. The settings menu for rooms has been redesigned
  2. It's now possible to assign and remove standard roles (admin and moderator) from populus viewer
  3. It's now possible to set power levels for standard events and actions from populus viewer
  4. It's now possible to ban and unban using the membership management modal
  5. Redacting the messages of others is now exposed as an action for those with that permission.

Besides that, I've been having some fun on the css-overhaul branch reorganizing some design elements, and centralizing the color CSS in a few variables, opening the way for things like a dark mode and user-definable themes. Here's a peek at the new milder and more welcoming default look:

gleachkr says

The permissions work now has us at one thousand commits. Here's to the next thousand! 🎉 As always, if you want to learn more, follow project progress, or talk about the future of social annotation on matrix, come join us at

Matrix Wrench (website)

Matrix Wrench is a web client to tweak Matrix rooms.

ChristianP announces

Matrix Wrench 0.7.0

I'm working on a few features for Wrench's anniversary on 13th June. Here's a bug fix for storing identities and a new button to check your membership status in a room.

  • Added: A "Am I a member?" button tells your membership state in a room.
  • Fixed: Unchanged identities got deleted from localStorage when editing identities twice.

Dept of SDKs and Frameworks 🧰

Trixnity (website)

Multiplatform Kotlin SDK for Matrix

Benedict says

After a few release candidates and weeks later, we released Trixnity 2.0.0 today! It contains many breaking changes due to a large refactoring, which allows us to share a lot code between server and client implementations of the Matrix APIs. This means, that Trixnity can be used to implement matrix servers in addition to application services and clients!

Trixnity finally has support for Kotlin/JS. You can implement a browser client or even better: multiplatform client. Support for Kotlin/Native will follow soon (e. g. for iOS clients). Right now, there is no trixnity-client-store implementation for JavaScript (e. g. IndexedDB), so you need to stick with InMemoryStore at the moment.

Besides notification support (push rules are evaluated), we introduced helpers to get the complete timeline as Kotlin-Flow (no more complicated loops to get the timeline). You can even subscribe to all timeline events, which is really helpful to implement bots with e2e encryption support. Speaking of e2e encryption: libolm is bundled into trixnity-olm jars, so you don't need to build olm by your own anymore.

These are the most important features. For the complete changelog, have a look at the release candidates.

Matrix Dart SDK (website)

Matrix SDK written in pure Dart.

Henri Carnot [famedly] announces

This week the team released version 0.9.0 which contains new features and some refactoring as many deprecated endpoints were removed so make sure to use the new ones when doing the migration. Support for the Element recent emoji (io.element.recent_emoji) was added. A new method to get the last read marker was added. Lastly, the timeline logic was enhanced, and it's now possible to load the timeline at a specific event. So you can load the room to the last event and then paginate through the new events. When reaching the last event, the timeline will automatically allow new events to be added in the timeline when received.

See you next week ;)

Dept of Ops 🛠

Cadair announces

I have spent the day ignoring more important things and trying to have something to TWIM. I wrote (yet another) GitHub Action for sending build status to matrix rooms. This action looks at all the completed jobs in your workflow and posts a combined status for the workflow as a message and reactions for all the individual jobs, inspired by the maubot GitLab plugin.

Dept of Bots 🤖


Hyperbased in Hyperspace says

Hello together. I made a generic bot, named Safed Sundarata, or Sundar in short, that should make it easy to get basic special functionality working. It has a lot of different functionality so you have an example code to work off of. The main motivation for this bot was to provide an !error <code> command for the developers in the ReactOS Matrix Rooms, which translates error codes to human readable text. Then of course i added other useful or fun commands to the bot. You want to read the Readme to find out more. This is the first time i ever wrote a bot, so feedback and corrections to the Source Code are highly appreciated. It is written in Go using the mautrix-go framework (thanks tulir and everyone who worked on this making it easy!). Even easier is to run and build it with go, no insane build system with broken dependencies required, which was the reason why i made it from scratch.

Mjölnir (website)

The moderation bot for Matrix

Gnuxie 💜🐝 announces


We have released v1.4.2 of Mjolnir which includes:


  • A new JoinWaveShortCircuit protection, thanks to Jonathan with This protection can be used to detect a mass-join scenario and set the room to invite-only.
  • Change of behaviour: Mjolnir will now apply server ACL and member bans to the most recently active rooms first (while syncing). The order was random before.
  • The causes of errors at startup (e.g. via misconfiguration) have been made more clear.
  • The image with the latest tag on dockerhub is now correctly in sync with the main branch.

Synapse Module:

  • The python module version is now in sync with the current git tag.
  • The Readme's example config has been fixed (thanks to Maranda ).

graim (website)

A bot to moderate communities bridged with Discord via matrix-appservice-discord

luphoria announces

I am releasing a brand new moderation bot, graim! This bot allows you to moderate communities that are bridged with Discord via matrix-appservice-discord. You can tie a Matrix account to a Discord account, and moderate both platforms seamlessly from either end! Graim supports one Discord server and as many Matrix rooms as you want, per instance. :) You can run it yourself from the Github - You can join the matrix space, which is bridged to the Discord server
