Dept of Servers 🏒

Dendrite / gomatrixserverlib

Neil Alexander announced:

  • P2P work is continuing at, with various fixes and a new public room directory
  • Room version work is continuing with new headered event support in Kafka, the internal APIs and the sync API in Dendrite, and in the event code in gomatrixserverlib
  • Joining rooms over federation is a bit more reliable now, as prev events are handled properly in this case and therefore the first message into the room doesn't get lost
  • Some improved error handling work has been merged - thanks to prateek2211 and abbyck
  • The /joined_rooms endpoint is now implemented - thanks to prateek2211

Notes on usage:

In order to try, do I need to create an account or should I be signing in to some user?

Just register as normal. Be aware you are registering into your local in-browser Homeserver, rather than a remote service.

Neil Alexander also mentioned:

We've also created as a general non-implementation-specific channel for homeserver developers :-)


TravisR offered:

v1.1.0 has been released with experimental (incomplete) IPFS support, memory leak fixes, and other improvements. This is a highly recommended upgrade if you use expireAfterDays or have memory problems.


Neil reported:

This week we have seen a huge increase in traffic and so we are spending a lot of time battling with scaling. Most notably we shipped an optimisation to improve state resolution for room versions > 1. Our sharding effort continues and we are working towards backing with redis for pub sub which is prerequisite for the project.

Aside from that we had some problems with push reliability, this should now be fixed. Sorry if you were bitten!

We also put out 1.12.0rc1 expect a full release early next week.

Next week performance performance performance. We’ll also complete improvements to user Interactive Auth for SSO installations.

Synapse Deployments

Mathijs told us:

The docker image for synapse v1.12.0rc1 is now on mvgorcum/docker-matrix:v1.12.0rc1

Dept of Bridges πŸŒ‰

Welcome Christian!

Welcome to Christian, who is joining the Bridges team as an employee. He'll start out on the Slack bridge but will be working more generally with Half-Shot on all bridges.


mx-puppet-bridge is a general bridging library that supports (double)bridging and relays. The goal is to make it as easy as possible for others to bridge new third-party protocols to matrix. Support room Donate

sorunome told us:

  • add adminme thanks to dhmf
  • more tests
  • unified namespaces!

Unified namespaces is a big update! This means that, if the remote protocol has globally unique IDs (e.g. as discord has the case) it will only create one room on matrix for any amount of puppets. Combining this with the advanced relay option, this means that protocol implementations (e.g. discord) now can act like a normal relay bridge only with super awesome puppeting! As in, the for the puppets, the DMs work and channels&guilds that the relay bot is not in. All this is possible without any changes to the protocol implementation, should the protocol have unique global IDs.

Dept of Clients πŸ“±

Quotient / Quaternion SSO support

kitsune told us:

In preparation to the upcoming (long-awaited) releases for Quotient and Quaternion, the library has gained full-blown support of SSO flow, such as the one used by the Mozilla's homeserver, and adventurous Mozilla Matrix users can use the master branch of Quaternion to login to their accounts. Next step - official releases and backports.

gomuks now supports markdown formatting in rainbow messages.

gomuks now supports markdown formatting in rainbow messages.


Nheko is a desktop client using Qt, Boost.Asio and C++17. It supports E2EE (with the notable exception being device verification for now) and intends to be full featured and nice to look at

Nico ( told us:

Emi added a new sorting method to the room list, that keeps rooms with unread messages on top, even when the messages are older than the messages in silenced or read rooms. It makes the room list a lot nicer to use and after being skeptical at the start, I now use it on all my systems. Huge thanks to Emi for bearing with my long and confusing review!

Riot Web

Ryan reported:

  • Keyboard shortcuts are more discoverable with a help popup that explains them
  • Jitsi support for voice and video is moving into Riot itself (the integration manager is no longer used for this)
  • Self-hosted Riots can be configured to use a different Jitsi server if desired
  • Encrypted messages are faster to encrypt and send
  • The room directory server selector has been reworked and is much easier to use and understand
  • Many cross-signing polish fixes continue to land, hoping to ship cross-signing in a few weeks

RiotX, Quick corrective release 0.18.1

valere told us:

Improvements πŸ™Œ:

  • Implementation of /join command

Bugfix πŸ›:

  • Message transitions in encrypted rooms are jarring #518
  • Images that failed to send are waiting to be sent forever #1145
  • Fix / Crashed when trying to send a gif from the Gboard #1136
  • Fix / Cannot click on key backup banner when new keys are available


Manu told us:

We are still working on cross-signing. QR code screens have landed on develop like storing and gossiping of cross-signing private keys.

Dept of SDKs and Frameworks 🧰


swedneck offered:

I'm working on a Gtk GUI for py-matrix-utils, progress can be followed at This isn't going to be a fully fledged matrix client, it's just a graphical interface for various matrix tools.
