Matrix v1.2 has landed! 🥳 Read the official announcement blogpost and check it out over at This release includes headlining features such as Spaces, room versions 8 and 9 which bring restricted join rules, as well as the new Matrix URI scheme.

I'd also like to point out that v1.2 released on 2/2/2022 :)

Otherwise, thank you to aaronraimist and devonh from the community for their fixes to the spec's text that merged this week. They are highly appreciated!

Random MSC of the Week

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

This MSC proposes to pave a way to allowing relating an event to multiple other events, which unlocks some additional use cases. Go check it out if you're interested in extending Matrix's capabilities even further!

Dept of Servers 🏢

Synapse (website)

Synapse is the reference homeserver for Matrix

Synapse 1.52.0rc1 is out, but honestly, we're just all hands on deck for FOSDEM tomorrow! As a reminder, members of the Synapse team will be giving a couple of talks during at the event:

Be sure to check out all of the talks in the Foundation & Community devroom or visit the Matrix stand for more freeform discussion — we'll see you there!

Dendrite (website)

Second generation Matrix homeserver

neilalexander says

Today we've released Dendrite 0.6.1 which contains a number of fixes and improvements. This release includes the following changes:

  • Roomserver inputs now take place with full transactional isolation in PostgreSQL deployments
  • Pull consumers are now used instead of push consumers when retrieving messages from NATS to better guarantee ordering and to reduce redelivery of duplicate messages
  • Further logging tweaks, particularly when joining rooms
  • Improved calculation of servers in the room, when checking for missing auth/prev events or state
  • Dendrite will now skip dead servers more quickly when federating by reducing the TCP dial timeout
  • The key change consumers have now been converted to use native NATS code rather than a wrapper
  • Go 1.16 is now the minimum supported version for Dendrite
  • Local clients should now be notified correctly of invites
  • The roomserver input API now has more time to process events, particularly when fetching missing events or state, which should fix a number of errors from expired contexts
  • Fixed a panic that could happen due to a closed channel in the roomserver input API
  • Logging in with uppercase usernames from old installations is now supported again (contributed by hoernschen)
  • Federated room joins now have more time to complete and should not fail due to expired contexts
  • Events that were sent to the roomserver along with a complete state snapshot are now persisted with the correct state, even if they were rejected or soft-failed

Spec compliance, as measured by Sytest, currently sits at:

  • Client-server APIs: 65%
  • Server-server APIs: 94%

As always, you can join us in for Dendrite discussion and announcements.

Homeserver Deployment 📥️

Dendrite Helm (website)

This chart creates a polylith, where every component is in its own deployment and requires a Postgres server aswell as a NATS JetStream server.

Till F. reports

Hi TWIM followers :)

dendrite-helm is an experimental Helm Chart to deploy a polylith/monolith Server.

After last weeks release of Dendrite 0.6.0, I finally updated my Helm Chart to finally reflect that.


  • Versioned releases (no morelatest docker tags or such)
  • locmai added dependencies (NATS JetStream, Postgres)
  • Update README (helm-docs)

Special thanks to locmai, who added the missing dependencies!


Dept of Clients 📱

Nheko (website)

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

Nico reports

It's FOSDEM! Don't forget to checkout my 5 min ramble about custom stickers and emotes in Matrx:

In preparation for FOSDEM, I've also been working on some goodies so that you can participate using Nheko in a limited manner:

  • Previews for rooms are now fetched for spaces using the hierarchy API
  • Widgets for the talks should be shown below the topic as links

While this isn't grand, it should be good enough for some to participate using Nheko. You will need the latest master (some commits aren't even pushed at the time of writing!), but if you are just watching, this should give you an easy way to fetch the talk link for each room. You will still have to watch the actual talk in your browser though.

LorenDB also added a big, fat, red offline indicator. If your server dies because of FOSDEM, now Nheko will tell you.

I hope you all will have a great time and I hope I see you around!

Populus Viewer (website)

A Social Annotation Tool Powered by Matrix

gleachkr says

Viewer Updates

Here's a big populus viewer update! Since last time, I've been mostly working on improving the user experience and onboarding for non-experts, as well as making my teaching-assistant bot a little smarter - this work is ongoing. But I have had time for a few new features 😁

  • Populus now implements MSC3592 - Markup locations for PDF documents, a proposal building on MSC3574 - Marking up resources, so there's a documented format for interoperable PDF annotations (though this is not the final draft, see below!)
  • I've reworked the sidebar for the PDF view, improving the aesthetics and allowing for a "fullscreen" view of PDF content.
  • I've added user-directory search and improved the usability of the invite modal.

The reason that MSC3574 is not a final draft is that I'm increasingly looking at the w3c's web annotation data model as a compelling foundation for annotations on Matrix. Stay tuned for a upcoming MSC, or come over to to talk about the future of annotation on Matrix!


I've also been working on a proof-of-concept for one Matrix use-case that I'm hoping Populus can help fill. Social annotation can be a good tool for getting feedback on works in progress, or for discussing new research with your team or lab. Wouldn't it be nice if you could just pop open a paper on a preprint archive and start commenting, or say "hey friends, I'm reading this paper, what do you think?" And wouldn't it be nicer if you could do that and host the discussion on your university or team's Matrix server?

Here's a first pass at that idea:

At the moment works by just pasting in paper codes from - it'll preview bibliographic information and give you a list of discussions taking place around a given paper, with the option to create a new one. Sessions are shared with populus-viewer, and pdfs continue to be hosted by the original archive. There are a number of clear upgrade paths, by integrating with a preprint archive that has an open search API, or even by adding an OAI-PMH metadata harvester to the backend, to combine the metadata from a bunch of open paper archives. I'm really excited to see where this work goes.

nehko-krunner (website)

A KRunner plugin to list joined rooms and possibly other things from nheko.

LorenDB announces

I have been working on a little project over the last week: nheko-krunner. nheko-krunner is a KRunner plugin that loads rooms from nheko, displays them to the user, and allows the user to activate said rooms. How does it do this? Well, I've also been creating a D-Bus API for nheko! This code has not been merged yet, but once it is, you will be able to create your own plugins that access nheko via D-Bus!

The current functionality of nheko-krunner is simply (1) search and switch to rooms that you are in (not unlike the Ctrl-K switcher), and (2) join rooms from their aliases.

If you want to try out nheko-krunner, you will need to build from the dbus branch in my personal fork of nheko and then install nheko-krunner from the above repo.

I hope that somebody finds this useful and I am excited to see what other D-Bus plugins may show up in the future!

Matrix Wrench (website)

Matrix Wrench is a web client to tweak Matrix rooms.

ChristianP announces

The versions 0.4.x brought improvements to the network log, letting you spot and investigate HTTP errors, bad JSON and network errors.

Ideally, I want to focus as much on the Matrix Spec as possible, but for the v0.5.0 I might venture into the territory of the Synapse Admin API, e.g. for listing and deleting media in a room. Please contact me, if you have use cases around media moderation you'd like me to consider.

Matrix in the News 📰

Carl Schwan says

The season 2 of Raising Dion (a Netflix TV show) featured shortly a video call with Riot/Element and a few other open source software (e.g. Karbon). Oh and you might recognize a few usernames in the sidebar 😅

Moe (Moritz Dietz) announces

Circles has made it into a small German speaking Apple News site/App called „Circles-App: Neue alte Ideen für private soziale Netzwerke“ There wasn’t a mention of Matrix - which is kind of exciting really. This means it can just be the transparent layer of great apps :)
