Spec Updates

This actually happened last week, but a huge shoutout to Kévin Commaille, aka @zecakeh, for their work on upgrading the OpenAPI schema data for the Matrix Spec to version 3.1. This schema describes all of the requests and responses for all endpoints in the spec, as well as various event types and other bits and pieces. It directly powers the Matrix spec website, the Matrix API Playground and several Client and Homeserver SDKs that generate code from it.

With a diff of +14,997 −12,660, this was a multi-month effort of both implementation and review (thank you @richvdh and @KitsuneRal!). This change will allow us to use all the new features that OpenAPI 3 has to offer, as well as generally keeps us up to date with modern tooling.

Thank you!

Random MSC of the Week

The random MSC of the week is... MSC3051: A scalable relation format!

This MSC describes a different way of describing how an event relates to other events. In the current Matrix spec, you can use the m.relates_to property to indicate that this event (say, a reaction) relates to another event (say, a message) in a certain manner. You can specify how it relates using the m.relates_to->rel_type key; a value of "m.annotation" for reactions.

But sometimes you may want to relate to multiple other events. For instance, what if that message you're reacting to is also in a thread? In fact, this MSC has come up recently as one possible way to solve the problem of efficiently discerning whether an event should belong in a thread or not (discussion). This MSC isn't the only option for solving such a problem - MSC4023 would also work, and both have tradeoffs.

MSC3051 could also allows for actions such as editing replies; both the text and the message it was a reply to. Neat!

Do read the MSC and give feedback if relations is something that excites you.

Dept of Servers 🏢

Telodendria (website)

An open source Matrix homeserver implementation written from scratch in ANSI C and designed to be lightweight and simple, yet functional

Jordan Bancino reports

A Matrix homeserver written in ANSI C, targeting POSIX operating systems.

  • Telodendria v0.3.0: v0.3.0 was just released earlier this week. It finishes out the client authentication portion of the specification, including a few basic profile management endpoints. This release also features full TLS support and some major architectural changes to make the code base easier to work with, the details of which I laid out in a previous TWIM.
  • Cytoplasm: A lot of the code that makes up Telodendria has been broken out into a separate C library for general-purpose use. I am calling this library Cytoplasm. At some point, it will live a life of its own, with its own website, releases, and Matrix rooms. But for now, it is still an integral part of Telodendria, so while it can be built and installed without Telodendria, you'll have to download the Telodendria source code to get it.
  • Coming Soon: I think the main thing that has a lot of us really excited around here is that the next step for Telodendria is implementing rooms and events. I'm hoping that the next release, v0.4.0, due around the end of this year, will have all of the necessary components in place to allow very basic communication between local users.

As always, feel free to say hi in, and for more details, join to read the full-length newsletters. If you want to support Telodendria, please donate to the project.

Synapse (website)

Synapse is a Matrix homeserver implementation developed by the core team

Shay announces

This week we released 1.86.0rc2. Here are a few of the highlights:

  • Support resolving a room's canonical alias via the module API
  • Speed up /messages by backfilling in the background when there are no backward extremities where we are directly paginating
  • Correctly clear caches when we delete a room
  • Enable support for MSC3952: intentional mentions

and much more. If you'd like to take a deep dive into the changes, you can find the release notes here and as always, if you encounter a bug feel free to report it at

Dept of Clients 📱

Neochat (website)

A client for matrix, the decentralized communication protocol

Tobias Fella says

Here's what's happened in the last three weeks of NeoChat development:

  • You can now create spaces in NeoChat. You can't edit them yet, but it's a start 😀.
  • NeoChat will no longer show outdated notifications.
  • As part of the matrixification of Itinerary (stay tuned for more info about that), Volker implemented support for viewing MSC3489 Live Location Shares.

Ement.el (website)

Matrix client for Emacs

alphapapa says

TWIM: Ement.el, a Matrix client for the GNU Emacs text editor and Lisp machine, has been released at v0.10. Changes include:

Security Fixes

  • When uploading a GPG-encrypted file (i.e. one whose filename ends in .gpg), if the recipient's private key or the symmetric encryption key were cached by Emacs (or a configured agent, like gpg-agent), Emacs would automatically decrypt the file while reading its contents and then upload the decrypted contents. (This happened because the function insert-file-contents was used, which does many things automatically, some of which are not even mentioned in its docstring; refer to its entry in the Elisp Info manual for details. The fix is to use insert-file-contents-literally instead.) Thanks to for reporting.



  • Activating a space in the room list uses ement-view-space (which shows a directory of rooms in the space) instead of ement-view-room (which shows events in the space, which is generally not useful).
  • Command ement-view-room, when used for a space, shows a footer explaining that the buffer is showing a space rather than a normal room, with a button to call ement-view-space for it (which lists rooms in the space).
  • Command ement-describe-room shows whether a room is a space or a normal room.
  • Command ement-view-space shows the space's name and alias.
  • Command ement-room-scroll-up-mark-read moves the fully read marker to the top of the window (when the marker's position is within the range of known events), rather than only moving it when at the end of the buffer. (This eases the process of gradually reading a long backlog of messages.)
  • Improve readme export settings.


  • Extra indentation of some membership events. (Thanks to Steven Allen.)
  • Customization group for faces.
  • Don't reinitialize ement-room-list-mode when room list buffer is refreshed. (#146. Thanks to Ted Reed for reporting.)
  • Don't fetch old events when scrolling to the bottom of a room buffer (only when scrolling to the top). (Thanks to Steven Allen.)
  • Minor improvements to auto-detection of homeserver URIs. (See #24. Thanks to Phil Sainty.)
  • Uploading of certain filetypes (e.g. Emacs would decompress some archives before uploading). Thanks to for reporting.
  • Messages edited multiple times sometimes weren't correctly replaced.

Jonas Platte says

Dept of Bots 🤖

TeXLily (website)

LoaD Accumulator announces

For a while, I and a couple of other people have been working and testing on a bot to parse LaTeX and LilyPond expressions. This allows people on clients like Nheko to send and see math equations on LaTeX(and even more, like custom packages, and TikZ support) and sheet music with LilyPond, both on normal, and encrypted rooms!

Check out the code(and maybe host your own): (mirror), (original)

maubot (website)

A plugin-based Matrix bot system.

wreck announces

I have written a handful of Maubot plugins which help me manage my private community on matrix, and figured I could share them a little more publicly with the world:

maubot-welcome is a greeter bot for when new users join a room, and can optionally alert admins in a separate notification room that someone new has joined. maubot-createroom allows admins to issue a simple command to create a new room and automatically connect it to a Space, saving you the trouble of configuring it with default settings manually. maubot-join is a helpful plugin that allows you to turn off Maubot's auto-join feature, and rest assured that only a known list of users can invite your maubot to any new rooms. maubot-kickbot will watch activity within the rooms in a Space and generate a report of inactive users. If you make your bot a moderator (or whatever your appropriate power-level is), the bot can also kick inactive users out of all rooms in the space and the space itself. Helpful for tidying up your community.

all of these plugins, and any other Maubot plugin I come across, can be found in a hopefully-easy-to-use list at Please feel free to submit more that aren't here!

flip-matrix-bot (website)

A Matrix bot for the Friendly Linux Players community.

HER0 announces

Hey, I haven't updated here in a while! Shortly after my last update, I did some refactoring work that made the code a little nicer and more testable, then added some more unit tests in, along with implementing CI. After this, I took a bit of a break from working on the bot.

Earlier this week, I implemented an idea suggested by a community member and contributor to the bot: users joining our main Matrix room ( ) are now greeted by the bot. This includes a random prompt/ice breaker to help get the conversation going. The first two times this was triggered, it spurred a bunch of conversation, so I'm pretty happy with it so far!

On the website side, the events page now lists the next upcoming event at the top. Outside of our development work, several FLiP community members participated in a Q&A session with GitLab, resulting in the following blog post (published last month): Building a more inclusive gaming community with GitLab.

Matrix Client Tutorial

uhoreg says

As promised, I've been working on the end-to-end encryption chapter of my Matrix client tutorial. I've recently added an sections on uploading device keys and one-time keys and keeping track of recipient devices, both which of were much longer than I expected (and they're not even complete yet). Next up is the Megolm encryption and decryption section. As usual, feedback is welome. The source code is at
