Spec Updates

Keeping in step with our quarterly spec releases, the release of Matrix v1.3 is expected to land sometime early Q2 2022. This release will include Threads (as defined by MSC3440), as well as a number of other MSCs which land in the meantime.

Speaking of other MSCs, client developers should be aware of upcoming work to support live and static location sharing in the ecosystem. A notice on the subject has been posted today in the Matrix Client Developers room.

A reminder that the matrix-doc GitHub repository has been split into two new repositories: matrix-spec and matrix-spec-proposals. Read more about this in the last edition of TWIM.

Random MSC of the Week

The random MSC of the week is... MSC2398: proposal to allow mxc:// in the "a" tag within messages!

This MSC makes the case for allowing linking to MXC content by using of an <a> tag in the HTML-formatted formatted_body field of a As MXC urls could contain HTML files, it could be rather useful to link directly to them, as you would any other webpage. Your client would then translate this to an http/s URL which can be used to view/navigate to the file.

Dept of Servers 🏒

Synapse (website)

Synapse is the reference homeserver for Matrix

Brendan Abolivier reports

We've released Synapse 1.54! It includes quite a lot of nice improvements, including around URL previewing, and new callbacks for third-party modules. Check out the release announcement for more info on all this goodness.

We've also landed more of the ground work to improve the time it takes for new servers to join big rooms, which Rich was talking about last week. Aside from this, we're continuing the effort towards switching Synapse to use Poetry, which will enable reproducible builds for Synapse. These are some very exciting projects which will be maturing in the coming weeks, so watch this space!

Homeserver Deployment πŸ“₯️

Helm Chart (website)

Matrix Kubernetes applications packaged into helm charts

Ananace says

Missed last weeks update, but my charts rolled along regardless. Currently serving; element-web 1.10.6 and matrix-synapse 1.54.0 (and matrix-media-repo 1.2.10)

Dept of Bridges πŸŒ‰

matrix-appservice-kakaotalk (website)

A Matrix-KakaoTalk puppeting bridge.

Fair announces

The basics of the bridge are now ready! Backfilling, message sending, and message receiving are now implemented...albeit quite buggy and untested.

For anyone curious to try it out, installation follows the same general steps as tulir's Python-based mautrix bridges, plus a backend Node module that must be launched before the Python component of the bridge. I'll write a README with proper setup instructions soon!

Just note that for the time being, updates to the bridge may invalidate its database!!. I won't guarantee stable DB upgrades until the bridge's early growing pains have settled down.

Reminder that my KakaoTalk ID is fair-mw if anyone wants to help me test things out πŸ™‚

Element (website)

Everything related to Element but not strictly bound to a client

Danielle announces

Welcome back to another week at Element!

Message Threads

  • Our MSC 3440 completed its final comment period this week which is a super exciting move forwards for our team! We are now using a stable prefix and server-side support for Threads so the whole experience should be much better.
  • The team is hard at work fixing bugs so that we can launch with as much confidence in our solution as possible.
  • If you’ve been using Threads whilst in Labs, please keep giving feedback and raising any issues you may find.

Community testing

Element Web/Desktop (website)

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

Danielle says

  • On Web we’re focussed on improving the app and fighting bugs;
    • This week we are seeing fewer reports of decryption errors!
    • On Develop, you should no longer find that editing messages messes with their formatting.

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

  • Pinned messages are getting some attention in Labs. Keep providing feedback for us!

Element iOS (website)

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

Manu announces

  • The next app store release is delayed due to some flows that do not match Apple guidelines - we’ll be updating the Apple SSO default values and introducing β€œDecline & Block” to invitations.
  • This week we checked-in on our language status and updated some things; We now support Ukrainian.
  • We’re working hard at updating the activity indicators in the app. While we work on the performance and load times in general we want to enable users to go about their tasks without being blocked by the activity indicator. The new indicator sits towards the top of the screen and should be out of the way for most tasks, whilst still informative. Let us know what you think!
  • The iOS team are also improving the onboarding experience for new users; aiming to make Matrix account creation as simple as possible.

Element Android (website)

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

Danielle announces

  • We’re continuing on our path to increase the quality and usability of the app; the next release is v1.4.4 (already available for beta testers!) includes things like moving the typing indicator from the top bar to the bottom of the timeline.
  • We are also improving our PR process. In particular we want to reduce the time the submitters have to wait to get a review.
  • Our onboarding flow is being updated. We want new users to have a simple and straight-forward experience when they’re creating an account.

Cinny (website)

Cinny is a Matrix client focused on simplicity, elegance and security

Lozenge reports

Namaste πŸ™,

We are happy to announce that Cinny now support all the features of Spaces β€” a way to group rooms in Matrix. This means that you can now create new spaces from client, add rooms or subspaces inside them or manage the added rooms. We have also made our unique feature of Pinning spaces to sidebar more easy and organized. With this option all the spaces and subspaces will be visible at one place and you can select the one you want to pin or remove. One more unique feature we added with update is the Categorized subspaces, what this do is make all the subspaces inside a space appear as categories. This is helpful when there are deep nested spaces inside a space and breadcrumb is pain to navigate back and fourth. Keep in mind that this ignore the nesting of subspaces and all of them will appear under mainspace, but nice thing is that you can select which subspace you want to categorized and which not. Another exciting update related to spaces is the Drag-and-Drop. Earlier there was no option to reorder pinned spaces but now with DnD you can reorder them as you like.

Apart from spaces this update also include option to drag and drop files, ||sending spoiler||, desktop notification and viewing event source. (Thanks to @ginnyTheCat for these amazing additions.)

Full changelog is available at:

Populus Viewer (website)

A Social Annotation Tool Powered by Matrix

gleachkr announces

In the last two weeks we've made some UX improvements:

  1. The PDF viewer now has nicer tooltips
  2. The width of sidepanels is now adjustable
  3. Searchbars now have hints to help find the keyboard shortcut
  4. Error messages are now displayed more uniformly
  5. Populus-viewer now has an icon
  6. Failed messages are now indicated, with the option to resend

Fixed some bugs:

  1. room avatars should now update more quickly
  2. highlights should always display immediately after joining a new discussion

And added a service worker, for a better offline experience.

Finally, we've opened a new draft MSC (just a stub at the moment) to create a format for annotations on text documents. So... matrix annotations as a vim plugin? The future is bright 😎

As always, if you're interested in this work, or in the future of annotation and scholarship on matrix, come join us at

matrix-streamchat (website)

Matrix powered stream overlay for OBS, to integrate live chat in your favorite (selfhosted) streaming setups.

f0x announces

Matrix Streamchat got it's first alpha release, and was successfully set up + used by someone else this week Recorded a little demo video on the setup with OBS:, and implemented the GUI for configuring the chat's settings and looks, to then copy the link into an iframe (embedded chat) or OBS (overlay).

Gatho (website)

Invite friends to your event with a one-click RSVP link - no matter which chat/social app they use!

Jake C reports is a replacement for Facebook Events for small social gatherings. I've used it for a number of parties and received great feedback, and I'm seeing others are starting to use it too πŸŽ‰

To receive confirmations of attendance you can either:

  • Use the included Matrix bot to automatically sync RSVP emoji reactions in a linked Matrix room (great for your friends on Matrix or in a bridged Signal chat)
  • Send a unique one-click RSVP links to you friends without Matrix (eg. Instagram DMs, SMS)
  • And as of this week, guests can "self serve" and add their own RSVP via the unique event link, so you can just drop the event link in a Facebook Messenger chat or iMessage group (without email or phone verification at the moment, so hosts will need to moderate if their guests go rogue and add multiple fake names!)

Other recent improvements are:

  • Ability to delete guests
  • Improved call to action and copy text for when a guest with a "magic" link is prompted to RSVP
  • Confetti animations when your guests RSVP via the Gatho website as "Going"

I'm currently testing an experimental chat embed using Matrix Live so your guests not on Matrix can optionally see your linked Matrix room - I've found some of my friends join Matrix after seeing this so they can join the action!

I'm keen to eventually use Cactus Comments once I figure out a bit of Elm and have more spare time so that non-Matrix guests can post too.

The Gatho website and bot is open source (AGPL-3.0) on Github, PRs and Github issues are very welcome! It's built using Next.js in Typescript.

I'd love to hear your feedback! Join the Matrix room at

Polyjuice (website)

Elixir libraries related to the Matrix communications protocol.

uhoreg says

Polyjuice Client Test is a tool for testing Matrix clients by creating a predefined environment for each test. Since the last time it was mentioned in TWIM,

  • more tests have been added: a test for basic end-to-end encryption message sending and receiving, symmetric key backup (MSC3270), and key withheld codes (MSC2399). More tests (and improvements to existing tests) to come.
  • the UI has improved a bit. Sorry, it's still ugly, but slightly less so. Also, now you can search through the tests.
  • I am now running a publicly-accessible instance of it at so you can test your clients without having to set it up yourself. This instance is stable-ish, in that it should always be available, but may be restarted randomly, in which case you may need to re-start your tests.

Dept of Interesting Projects πŸ›°οΈ


unonde says

hello! wanted to show a small matrix web client made with unminified js/html/css & web components (wip++) + looking forward feedback comments or anything, cheers & viva la matrix!

for now it only uses default matrix messages, and it is read only, so users have to login/register/CRUD through element (or any other client) the idea would be to give back users control on their data, allow them to "collect" (individually or as group), any type of content, gathered into matrix room

For now, the client is making HTTP requests to matrix API, to fetch the data of a (public) room, all message & state events. it also give a "clean URL" so users can access their "profile" (chat room) easily (just like a twitter, instagram, medium) page

Self-Host a Matrix Map Server

JulianF reports

Following Element's recent announcement of location sharing with support for self-hosted map tile server, I went ahead and set up one, and have written a blog post about it, explaining how to go a little further than the currently published guide, and with Ansible scripts included. *>

Extensible Events

andybalaam reports

Andy Balaam wrote a blog post explaining extensible events - it shows simple examples of what message events look like now, and how they change with extensible events. It also covers the abbreviated forms of m.message: m.text and m.html, which can make it somewhat more confusing to understand.
