Huge update from Andrew:

This week’s stats for Dendrite are in! 4 authors have pushed 11 commits to master and 11 commits to all branches. On master, 48 files have changed and there have been 676 additions and 146 deletions.

Of note are the following merged PRs:

We also have a number of PRs that were moved forward but not merged. Add auth fallback endpoint (our oldest PR at the moment!) which we mentioned last week is so very close, but not quite there in time for this TWIM.

In terms of passing Sytests, Dendrite now passes 172 tests, up from 167 last week. This is out of 761 tests in total. So just a small bump (0.6%), but note that things that are crucial for Dendrite development at the moment, such as federating, only cover a small subset of tests, so each passing one can bring us much closer to getting Dendrite usable day-to-day.


From Neil:

The big news this week we’ve landed some massive DB improvements ( which should make message sending on (and any other server) feel noticeably snappier. :) It'll be in the next release.

Outside of perf, we’ve also been continuing with our privacy project, sydent now supports hashing third party identifiers instead of storing the raw form, and in the coming week we’ll look at minimising the meta data we store. You can track our progress across the full project here (

Work continues on our installer to make it easier to configure Synapse and we’ll be looking for some community feedback rsn. The room directory revamp is now very close and we hope to have something live on in about a week.

Finally we’re working on improving the efficiency of smaller instances sending messages into large rooms, we’re still at the design stage, but it will make a huge difference for anyone self hosting.

andrewsh also informs us:

synapse in up-to-date in Debian unstable — and in buster-backports (uploaded last week)

TravisR announces various unstable interesting things


If you fancy running highly experimental software on your homeserver which might break things, I have two things for you:

  1. matrix-key-server ( ) is an implementation of a Matrix key server with notary support. Although it follows the specification, it has not been tested against Synapse. It is however fully featured: check it out on the federation tester ( ) or by querying it yourself ( ).

  2. matrix-room-directory-server ( ) is less experimental than the key server but is still very early days. Currently it only offers the ability to manipulate the federated public room directory for your server, but in future it is planned to be its own standalone directory server (room aliases without having to run a whole homeserver). Check it out by searching the room directory from your client.

Dept of Clients 📱

Continuum progressing!

I love getting updates from yuforia - they've been consistently working on Continuum for some time, and by increments are making a great client.

Reuse the ListView of messages across different rooms to reduce memory usage (Experimental) Remember and refocus the last read message, making it easier to go through all unread messages while switching chat rooms freely.

QMatrixClient is now Quotient


Renaming of QMatrixClient to Quotient has been finally merged to the master branch; Quaternion master uses it from now, too. Packagers are welcome to make test builds and report bugs in libQuotient 0.6 beta is coming close now!

Riot iOS

  • Test on iOS 13 Beta. Beta 6 fixed most bugs discovered on Beta 5
  • Released 0.9.2 (Waiting for Apple review at the time of writing)
  • Working on privacy concern.

ma1sd 2.1.1

ma1uta announced ma1sd release 2.1.0:

Changes: reworked unbind (MSC1915).

Now ma1sd is compliant with the MSC1915 (unbind).

and then 2.1.1:

ma1sd release 2.1.1 with the security fix and more strict request validation, allows only requests from ma1sd's matrix domains (mirroring bind). Download links: (archives and the deb package) and for docker image.

Dept of Bridges 🌉

mautrix-facebook, mautrix-telegram and the tulirverse

tulir has been making big updates to two of his bridges:

mautrix-facebook can now bridge formatting, mentions, replies and reactions in both directions.

There is also a logout command now.

mautrix-telegram's switch to mautrix-python is nearly finished (i.e. it didn't cause any errors for the past few days when testing in production). The main reason for the switch is using one Matrix library for all my python bridges. It also means the bridging code like double puppeting and command handling I shared between mautrix-facebook and mautrix-hangouts is now also used in mautrix-telegram.

Visible changes directly caused by using mautrix-python:

  • Logs are now colorful.
  • Python 3.5 is no longer supported.
  • The bridge will refuse to start without access to the base config file.

Other changes that happened during the switch:

  • Telegram "Saved Messages" can now be bridged even when using double puppeting.
  • Mentions on Telegram are marked as read when using double puppeting (messages were already being marked as read, but mentions weren't).

Also, this actually happened last week and the week before that, but anyway: I've moved the CI and docker registry of my active projects to a self-hosted GitLab at Specifically, the CI/docker registry for all four mautrix bridges and maubot and automatic builds for gomuks have been moved. My maubot plugins also have automatic .mbp builds in the CI. For the docker registry, prepending to the existing image names will work. The old places (docker hub, won't get new builds anymore. The repos on GitHub are still the "canonical" repos, but they're mirrored more or less instantly with maumirror.

He adds:

mautrix-telegram will probably get some sort of history filling in the near-ish future


I'm going to add some way to put bridged rooms into personal communities for filtering purposes. Not yet sure if it'll be fully built into the bridges or some kind of an external script

IRC bridge RC


Hi folks, we've released a RC of the next irc bridge version. Check it out at


Slavi, famed for his ansible playbooks, announced:

I've just released Email2Matrix - an SMTP server that can relay incoming messages over to Matrix based on mappings defined in a configuration file.

While it can also be installed standalone and work with any Matrix homeserver (see its documentation), the simplest way to install it is using matrix-docker-ansible-deploy and its guide for Email2Matrix installation.

The configuration process (users, rooms, mappings) is quite manual, but it's simple and has worked well for me for the past year and a half. I've only just polished it up a bit, released and integrated with the Ansible playbook, so others could benefit from it too.


mijutu appeared, and announced:

I started a "matrix-xmpp-filter" project. It's like matrix-ircd, but with xmpp instead of irc. It can also filter messages by weekday, time and regular expressions. Target audience is Sailfish phone users, but it could be used with other xmpp clients too (no xmpp MUC support required).

matrix-github (GH issues bridge)

Half-Shot: has had quite a few updates. Notably:

  • Support for storing users access tokens securely, using a bot command.
  • Multi-process bridging: The webhook portion of the bridge can be run in a separate function if needed for performance.
  • Images and mentions now work in both directions
  • The readme is now actually helpful, and have also made *.sample.yaml files.
  • You can now use it via oauth

Currently working on a Puppet module to manage Matrix Synapse installs (both directly and through docker), not quite ready for prime-time yet but watch this spot.

Dept of Bots 🤖

Voice to text bot

progserega announced:

I develop matrix Bot, which converting voice messages to text. It use Yandex Speech API and Yandex API cloud (some as aws) for temporary store voice-data before converting. Bot have such logic:

  1. user add bot to room (for example room with whatsapp bridge users - now bridge support adding bot to such rooms)
  2. bot listen room, and when get voice-message - send it to Yandex-cloud for translate (now support only Russian language).
  3. When translating is success - bot get result text and show it in room as notice, such: "Username said: text"
  4. Bot also receive some command, which allow disable it in this room, or disable translating for user, which send command..

Seeing this, I wondered, "y tho?", luckily progserega was able to explain with a graphic! They say a picture paints a thousand words, and it's clear from the conversation below why he'd want to have speech-to-text capabilities.

Dept of Servers 🏢


This week we’ve been working on implementing identifier hashing in sydent, a brand new installer for Synapse, we’ve trialled some new db perf improvements which look very promising (more on this soon) and finally very close to an all new implementation of room search.

Next week we’ll push out the all new Sygnal, continue with the installer and room search and pick up some tasks under our privacy umbrella to ensure that Synapse is not holding onto any data that it does not strictly need to.



Dendrite progress marches forwards. This week we had:

  • Room tagging implemented (thanks peekay_46!)
  • A PR for redactions opened by our GSoC student cnly
  • A PR for authentication fallback (for when clients don’t have a web browser built in and want to use recaptcha from trion129
    • This has been in the works for a while, and just has a couple small changes left to go!
  • Two PRs for filtering database functionality from CromFr
  • A PR for fixing the scope of transaction IDs in Dendrite’s transaction cache from cnly

Cnly’s GSoC period ends on August 26th. He has been a massive boon to the project’s cadence so far and we hope he will continue even after GSoC ends when he has time :)

koma, Kotlin Library

yuforia has this update about koma, the library used to power continuum:

Provide automatic deduplication and rate-limiting when downloading media resources. This improves performance of GUI applications, where avatars of many users may appear on screen at once, and some of them may be identical.



libQuotient's master branch now supports sending and receiving reactions, and receiving message edits. We also have another PR in the works from aa13q that would add support for events decryption, as a part of his GSoC endeavour.

Fractal 4.2 released

Alexandre Franke announced a new edition of Fractal:

Nightlies of Fractal are currently stuck on a 2 weeks old build because of one of our dependencies… but the long awaited 4.2 stable release is out! You can get it out fresh from flathub as usual.


New features:

    Adaptive window, mobile friendly
    Window size and position are remembered
    Redesigned login
    Network proxy support
    Typing notifications
    Badges are shown for operators and moderators
    Keyboard shortcuts for easier navigation across rooms

Better uploads:

    Audio and video files are now tagged correctly
    Image files have a thumbnail
    Various tweaks to the file chooser


    Logs actually output something now
    A few issues with invites and direct chats have been resolved
    More reliable scrolling
    Some crashes fixed

Under the hood:

    Code refactor continues
    We’re now using Rust 2018
    Many improvements to the build system and CI

Neo huge update!


Lots of news about Neo!

  • There's now an additional maintainer (joepie91)!
  • A lot of the internals have been refactored, so they should be more maintainable and reliable going forward. Also some future work planned on refactoring the state handling using Redux, which should make it much faster to fix issues and add new features in the future. There are even some ideas already for a future plugin API!
  • Display has been improved in a lot of places. Error messages are now more clearly formatted, images in reply-quotes are now shown as thumbnails rather than just a filename, and the reply-to popup now shows the full event that you're replying to properly. The chat window now correctly sticks to the bottom when you're scrolled to the end and receive new messages, even when an image or video loads - though per-room scroll position restoration isn't done yet.
  • There's now an experimental compact mode! It uses a more IRC-client-like layout for messages, and generally just fits more content onto the screen. It can be enabled with an experimental flag. A screenshot of the compact mode can be found here.

You can try the compact mode at

Dept of Bridges 🌉


Hey folks, first an update from the bridges integrations side. We've brought back snoonet and oftc on the integrations menu so you can once again connect matrix rooms to these networks. Other networks should work as standard.


Half-Shot again:

On the matrix-appservice-irc side we've made a few fixes to the handling of IRC modes (things that handle how users should behave) when bridged to IRC. This should hopefully make opping and voicing users more reliable. There are a few other fixes in the pipeline too, so a release isn't too far off.

GitHub issue bridging !?

Half-Shot AGAIN:

I had an adventure this afternoon into the world of bridging again, and have made a Github to Matrix bridge. At the moment you can join aliases and saturate your homeserver with the entire history of a issue or PR. You can also chat to folks on issues in realtime.

CLI federation tester

kai is someone with no fear of rapid iteration! Versions 1.2, 1.3, 1.4 and 1.5 of his script were made available this week:

I finished version 1.5 of my small command line based federation tester. The bash script relies heavily on popular Unix tools like awk, curl, jq, sed and so on. Compared to, the outputs are a little more detailed and additional tests are performed, especially on the supported SSL protocols. Currently, it has only been tested under Linux.
The current version improves the handling of port in the .well-known and DNS SRV configuration.

jcgruenhage has been working on a bot in relation to the startup he's working with:

I made a bot for issuing Json Web Tokens to matrix users based on what homeserver they are on. It's implemented as a maubot plugin (best way to write bots right now) and licensed under the AGPLv3. You can find it over at, and talk about it in
As for the usecase, we want to give people from customer homeservers access to an API component, but don't want to maintain a separate account database. This way, they can request a token from the bot and then use that to interact with the API component

Matthew informed the community:

We're getting more and more folks reaching out for paid help setting up smaller self-hosted Matrix deployments. The core team has its hands full currently with helping out with larger deployments; so if anyone reading this wants to offer paid support to those getting up and running on Matrix then please make us aware so we can potentially route inquiries to you.

This is a great step for Matrix, and a great opportunity for you the reader! There are already several people prepared to start work on Matrix-related endeavours, but the fact that there is more work coming in than we can currently route is amazing. If you'd like to be on an informal shortlist, contact support@, or come chat to me directly.

So said Neil, who oversees the Synapse-makers:

This week we shipped two new versions, 1.2 ( and 1.2.1( 1.2.1 contains critical security updates, the bugs are long lived and not regressions introduced in 1.2 so all admins are encouraged to upgrade asap.

We’ve also been having some success in improving database performance and hope to ship that rsn so everyone can benefit.

Next week

We’ll continue on db perf, improving logging verbosity (through recategorising some log lines) and generally looking to improve the experience for those admins running on smaller instances.

GSOC project: Matrix Visualisations 🎓


The GSoc project “Matrix Visualisations” has continued its progression during the second period:

A “multi-view” has been implemented for the frontend application. It means that it is now possible to independently view multiple DAGs at the same time in the same canvas. It can be useful for observing the same DAG but on different HS’s, at the same time. The only current limitation is that you have to use the same backend for every view (with CS API or with the backend talking to a Synapse PostgreSQL database). This change took a long time as it required to make a lot of changes in the code.

The implementation of the support of the Federation API within the backend is in progress. It is slowly progressing as it needed some discussion before starting the work on it and its implementation requires me to become familiar with a lot of new things, regarding the federation process and the authentication of requests between HS’s.

Pattle 0.10.0

I've been playing with Pattle 0.10 and have to say, it feels silky smooth to scroll with. It's really making me look again at Flutter development.

From Wilko, project lead:

A new version has been pushed to F-droid and TestFlight!

Note that for TestFlight the new version will be available in a few days.

  • Improve scrolling through chat messages!
    • Messages are now paginated under the hood, before the whole message list was rebuild when loading more messages, causing a jittery scrolling experience.
  • Support typing notifications!
    • Typing notifications are shown and send while typing.
  • Add chat settings screen
    • Currently you can see the chat name, avatar, description and members. More will be added in the future.
    • You can go to the chat settings screen by clicking on the title of the chat. This'll probably change in the future (at least to be easier).
  • Reverse swipe direction of images (thanks Nathan!)
  • Fix ripple not showing on send button
  • Make UI refreshing more efficient
  • The App Store (iOS) name is now 'Pattle' instead of 'Pattle IM'
  • When a chat is open, the UI will only be rebuild if that chat has updates.
  • Lot's of code clean ups and improvements, mostly in the SDK

What's coming up?

  • A release on Google Play!
  • A release on the official F-droid repo!
  • Remove Cupertino specific styling on iOS
    • Will now use Material Design, but altered for iOS. Having the discrepancy between Cupertino and Material was also the reason why some things didn't show up in iOS or why some things would be blue instead of the Pattle red.
  • Notifications!? (F-droid)

Follow development in!

Half-Shot announced:

0.3.1 of the slack bridge is out with a few bugfixes

Be sure to watch Cadair provide a demo in the Matrix Live video above.

Picard Bot (slack bridging)


SolarDrew and I have been working on re-writing our Picard Bot for a conference next week. Picard helps you bridge between a slack team and a matrix community.

This second version of Picard adds support for reacting to creation of new rooms on slack in real time as well as implementing a set of commands for creating new bridged rooms from either matrix or slack. In addition to this, Picard has matrix commands for inviting you to all the bridged rooms in the community and automatically inviting you to new rooms as they are created. Finally, we have added support for sending welcome messages to all new members of your slack team or matrix community in a DM with the bot, which we are using to explain the chat setup to users and giving them a private place to issue commands.

This is uses matrix-appservice-slack for actually sending events in bridged rooms, and PIcard itself is a skill for the opsdroid bot framework and uses the matrix-database plugin for opsdroid which uses matrix room state to back the opsdroid memory.

mx-puppet-bridge, new bridge: mx-puppet-instagram

The work on mx-puppet-bridge things continue! The core library and the implementation received some bugfixes, however, a new bridge is there: mx-puppet-instagram. Currently it supports

  • Auth currently only by username+password :(
  • basic message sending
  • I->M photoes, voice messages, animated image thingies
  • M->I images
  • M->I files as links only


tulir has been putting a lot of time into WhatsApp bridging lately, the bridge is more stable than ever:

There's a mysterious new mautrix-whatsapp branch. Related to that, I made a spec proposal and a synapse PR to allow appservice bots to use /sync.

GSoC Project: Reliable Bridges

Thanks for this update from Kai:

It's all coming together now. While all pieces of the puzzle were roughly there, now they are put into the big picture.

The bridge SDK PR has been merged to develop, now providing bridges the benefit of error reporting. The modifications to the SDK are non-breaking, but activation of the feature requires small changes to the bridge using it. But be warned, everything is still under an unstable prefix and rightly so – the implementation is still subject to change. >

The MSC didn't get much love in public, but the concepts required to evolve it are taking shape. It was contemplated to piggyback on MSC 1410: Rich Bridging and to add a retry mechanism. So heads up for more to come on this front.

The display of bridge errors in Riot Web is now a PR and in the state of getting its last few kinks removed. It will start to be available under a lab flag soon.

With everything getting to play together nicely, there will be the first rooms enabling bridge errors to test the code in the wild. Stabilizing the code for everyday use and getting the MSC into a respectable form are the next goals for the project. Those will help in fostering broader adoption among bridges and clients.

Spec News

(not quite matrix) feneas call for comments on spec for metadata


I'm working on a specification for exporting metadata and usage metrics out of federated servers. The aim is that the same specification could be re-used cross-protocol for example with not only Matrix servers but also ActivityPub, Diaspora and XMPP servers, as an example. Looking for comments here:

Dept of Servers 🏢



Feature Updates

Dendrite continues along with more development from anoa, our resident GSoC student cnly, and a few community members. cnly has been working mainly on fixing up /sync issues and other areas of the CS API, fixing the various federation issues, mainly those dealing with room state, and various other maintenance tasks around the codebase that are highly appreciated. peekay_46 has been hard at work completing Dendrite’s implementation of room tagging and trion129 returned to continue with adding a fallback page for recaptcha (for clients that can’t render web pages). We have a number of community PRs still with active members, but most are waiting for reviews, which anoa is working towards.

The Plan

A couple TWIMs ago we teased that Dendrite had a plan in the works. Well one meeting later and here is the proposal:

It will take a while for Dendrite to become feature complete with Synapse, but we’d like people to be able to actually use Dendrite before then. Instead of waiting for feature-completeness, we propose a set of milestones for Dendrite development to reach and prioritize development for.

These milestones are currently listed on Dendrite’s github. The first is “Bot Hosting”, which means, once complete, Dendrite would be suitable as a “bot hub”, allowing server admins to run massive bridges on top of Dendrite while taking advantage of its horizontal-scaling capabilities. As written in the description, this goal includes basic CS API support, as well as federation with other homeservers. At this stage Dendrite should already be usable in rooms with other Synapse servers, which should make it a lot more interesting.

After that is several more milestones, each representing another use case that Dendrite can fill.

Don’t be alarmed at the currently quite small percentage of completeness, as these milestones have just been built from the open issue list. We’re actually quite far along to #1 already :)

We also want to mention that the milestones aren’t completely built yet - there’s still a few more issues to comb through. It’s taken a few days as anoa can’t help himself to fix things as he goes along. A few open issues have also been closed as they had already been fixed earlier.

This is all mentioned in this week’s Matrix Live above by the way, so be sure to catch for some extra details if you’re interested.

We look forward to shipping you a working Dendrite soon™. And as always feel free to join us in for discussion.


Neil, who oversees the Synapse factory:

This week we’ve been working on improving database performance, shipping the new small hosted homeserver instances - expect a lot of improvements to come that will benefit the whole community and merged our recent OpenTracing support. We’ve also made some changes to how Sydent processes and stores email - more details here

Next week, expect a new release, more database performance improvements and general Synapse performance work.

This Week in Ruma, from Jimmy:

While I was working on ruma-signatures, I decided to fill in the missing functionality—signing and verifying events. In the process of doing that, I ended up with a significantly revised API for the crate, which has now been released as version 0.5.0.

New matrix-nio release bringing you documentation improvements across the board, while the documentation is still not fully complete yet it should be much easier to get started with nio.
Another highlight of this release is couroutine support for the event callbacks for the AsyncClient.

Take a look at the getting started guide too.

Ruby SDK


I just cut a 1.3.0 release of the Ruby SDK, mainly focusing on solving an issue due to Ruby extensions polluting the global scope. It also adds a very slightly extended response handling, which recursively adds getters for the keys of the resulting objects.
Many thanks to the people reporting issues to me so I can keep improving the SDK.

The Kotlin library koma

yuforia, author of koma and Continuum:

  • Fixed incorrect type casting in function
  • Reorganize the structure of modules, separate APIs that don't require authentication, so that they can be used before signing in

Dept of Bridges 🌉


Half-Shot announced:

Today we've released 0.3.0 of the slack bridge since the last rc has proved to be stable. I hope you all enjoy the new features we've packed into this release. And as a reminder, there is another release right around the corner :)

Dept of Clients 📱

RiotX (Android)

From the team (see Matrix Live from last week for more from them):

  • RiotX 0.2.0 has been released on Thursday. Main new features: room filtering, message editing in e2e rooms, view editing history. Also many small new features and bugfixes.
  • The team is still working on the main missing features: creation of direct chat, read receipt, along with UI/UX polishing.

If you're using Android, definitely start trying RiotX, you can even find it in the Play Store now.

Riot Web

From the team:

Riot v1.3.0 was released with support for reactions and message editing enabled. Check out the Riot blog post for more details. No changes are needed to enable these features for self-hosted installs anymore (which is change from what was stated in last week’s TWIM update).

We’re continuing to work on several privacy improvements to related to integration managers and identity servers to give users more control over these.

Riot Android

From the team:

Riot 0.9.2 has been released on Friday. It contains some bug fixes and new translations for many strings especially for the device verification feature.

Riot iOS

From the team:

  • We released v0.9.1 with message editing, reactions and file upload.
  • We are continuing to work on reactions (emoji picker).
  • We have started to implement soft logout.



In the newest update FluffyChat now supports avatars in Push Notifications. Also translations have been updated and some minor design tweaks have been made.

I know that E2EE for FluffyChat is continuing to be worked on, just not quite ready yet.

Continuum, client based on koma

yuforia, author of koma and Continuum:

  • Update GUI library openjfx from version 11 to 12
  • Rewrite build script in Kotlin, replacing Groovy

Fractal, GNOME client

Alexandre Franke on Fractal:

Several bugs were fixed in the past three weeks. We are also sending typing notifications now. With 4.1.1 out, we’re at the second beta on the way to 4.2.


some people might be interested in a tweak in our build config that makes it so that crashes are aborts now (i.e. you get a trace and they are not silent anymore)


Black Hat is changing Spectral's buildsystem from QMake to CMake.

sendtomatrix script

Madic has created a shell script to send messages to a room:

I've written a linux shell script with which you can send (multiline) messages to a matrix room. It only needs a username / password or access token, server fqdn and roomid as argument or provided by a configuration file. Arguments can overwrite settings from the file, for e.g. using same credentials but different channel. If no access token is provided, a new one will be requested and used to send the message. You can use the script for e.g. cronjobs, nagios notifications or ci pipelines. An example for a cronjob and a nagios notification script is also provided.

12.07.2019 00:00 — This Week in Matrix Ben Parsons

Matrix Live: RiotX

Nice! Manu and Benoit, who work on the Riot Mobile, discuss the development status of RiotX.

Dept of Servers 🏢


A bit of everything this week, we’ve made changes to support the upcoming edits and reactions release, worked on soft log out, experimented with improving general perf for small homeservers, landed open tracing support, improved db query load.
Next week we’ll see about landing the small homeserver perf improvements, work on id hashing in sydent, fix some e2ee bugs (made easier to track down with OpenTracing), do some more database performance work and start gradually rolling out the new Sygnal instance.


Jason back on it:

This week in Matrix, Construct made the crazy-loading mode of client sync the default. Crazy-loading is an approach to initial sync that goes beyond lazy-loading for a better UX. It's even backwards compatible with clients that don't support lazy-loading.

Construct also made significant progress on implementing version 3 and 4 rooms during the week. This is nearly complete, and should be ready for testing by the weekend.

Good to know there is progress with new room versions as more and more rooms start to be moved over to v4. for testing and more info.


This week we’ve implemented profile retrieval over federation, single event retrieval, room tagging as well as host of bug fixes.
Next week we’ll be looking at state resolution and implementing our latest and greatest algorithm needed by modern room versions.

This Week in Ruma

Jimmy provided This Week in Ruma:

Work continues on the major revamp of ruma-events mentioned in the last update.
There are also a few modules that are somewhat blocked on an issue in ring. Some of the types in ruma-events contain types from ruma-signatures which don't implement Clone and PartialEq because they contain types from ring which don't.
Rust 1.36 was released, and it includes stabilization of the Future trait, one of the long-awaited building blocks for first-class async support in Rust. [...] the biggest reason for Ruma's development hiatus is waiting for async networking in Rust to mature, and this is one of the final pieces of foundational support we've been waiting for. The remaining pieces are async/await syntax, which is expected in either the next version or the one following it, and finally, waiting for important libraries like Hyper and Tokio, as well as web frameworks, to adopt the new stuff.

libQuotient gets .well-known support


Thanks to Black Hat, libQuotient gained support of .well-known - a very useful feature to connect to Modular-hosted homeservers!

Also, the first block of E2EE functionality from aa13q has been merged to libQuotient master - so far it's just uploading the keys but receiving messages is already well in the works!

Dept of Bridges 🌉

mautrix-telegram v0.6.0


mautrix-telegram v0.6.0 was released. Recent changes include bridging strikethrough, underline and nested formatting to telegram and some bug fixes, including one security fix. Full changelog on GitHub.

Debian 10 was also released recently, which means v0.6 is the last version with Python 3.5 support. Starting from v0.7.0, mautrix-telegram will only support Python 3.6 and up.

mautrix-telegram v0.6.0 also includes Native Matrix edit support, message editing between platforms.

matrix-appservice-slack 0.3.0-rc2

Half-Shot and the Slack-bridge-gang have announced matrix-appservice-slack 0.3.0-rc2

Hi folks, the slack bridge has had another RC release this week 0.3.0-rc2 which has been deployed onto :). In other news, we are nearly done with the port of the bridge to Typescript (slated for the 0.4 release) which has allowed us to clean up the codebase significantly and splat a lot of bugs.

I'm for any movement toward TypeScript - seems to be a winner in the JS-world. Says Half-Shot:

I'm a bit fanatical about Typescript, it's objectively better to write things in TS than JS if you have the freedom to do so. It's also allowed us to keep the bug count down on the Discord bridge, so I'm starting to look at the other bridges for typescript support too.

Reliable Bridges GSoC project 🎓

Thanks Kai for this update!

The new Spec proposal MSC2162: Signaling Errors at Bridges landed! It is about adding permanent errors: The ability of bridges to mark events as not delivered to all participants. While there is already code supporting the feature, the Spec process is important for getting everyone on board and finding potential problems with the current approach.

In spite of being a relatively small proposal, there were already a lot of suggestions and directions in which it can evolve. Shoutout and thanks to everyone who already contributed to it with their comments!

Meanwhile on the more practical front a fork of Riot Web was extended to now support the actual visual display of bridge error markings on messages.

See it in action:

RiotX big announcement!

  • We have released a beta version to the PlayStore on Thursday! You can download (and rate it) here: . Also feel free to join to provide any feedback!
  • You will find more details about what RiotX can (and cannot yet) do here:
  • Now we are working on fixing bugs, and keep going implementing the missing features

I've been using RiotX a lot lately and find it great - really snappy.


Black Hat:

Spectral supports .well-known now obviously. see libQuotient update above
Also a lot of changes:

  1. Bubble shapes for pending events are fixed.
  2. You can set device name when logging in. This becomes important as libQuotient begins to upload one-time device key as part of E2EE implementation.
  3. Markdown is parsed automatically by default, and works with replies.
  4. Small UI improvements in timeline and room list.


yuforia has continued work on Continuum, a desktop client written in Kotlin:

Continuum now preserves media content URI (mxc://) internally in order to treat them specially, instead of converting to all URI to http (or https) upon receiving.
This week's version never considers cached mxc resources stale and no network request will be performed for refreshing.
Continuum also loads previews for http image links in text messages automatically. The usual http cache control rules are still followed in those cases.

Join to chat more about Continuum, or about koma, the underlying library.

Riot Web

Riot v1.3.0-rc.1 is now ready for testing at This includes some last minute polish of reactions and edits, and also adds initial support for soft logout. This release will have reactions and message editing enabled via configuration on once it stabilises.
Self-hosted installs that wish to do the same would need to alter their config.json in similar fashion. This is because these features currently depend on unstable APIs, and we don't want to move them out of labs and fully on by default until that is resolved.

Riot iOS

  • Reactions and edits:
    • Enabled by default (no more LABS setting)
    • Reactions with non-unicode keys
    • Original event in the edit history (need homeserver update)
  • Upgraded rooms are now autojoined when tapping on the upgraded banner
  • File upload from the room screen and from the share extension
  • Crypto: logs have been improved and a script has been created to help to debug e2e bugs (see the screenshot at
  • This Friday TestFlight can be considered as a release candidate

matrix-docker-ansible-deploy: synapse-janitor now available


Thanks to Aaron's frequent mention of synapse-janitor and other such cleanup methods, I've finally gotten inspired enough to give it a try.

The playbook now contains a new Synapse Maintenance documentation page and an easy/safe way to run synapse-janitor.

To give an example, using synapse-janitor and a full Postgres VACUUM yielded a 29% reduction in disk space used by Postgres on my personal homeserver (5.3GB -> 3.8GB).

Alexey Murz Korepov also reminded us about synapse-purge, which we've mentioned here before - but is designed for a similar purpose.



the avhost/docker-matrix image has moved to a debian buster base image, which got us an upgrade from python 3.5 to python 3.7.3 and jemalloc1 to jemalloc2, which should improve the performance of synapse.

Dept of Articles 📝

Pneumaticat: "wrote a blog post on integrating Riot chat with our dapp & scientific research auditing platform, Delphus!"

Final thoughts 💭

I had/stole the idea to create a bot which uses message edits to send frames of an ASCII-art animation. I indeed created the bot, which works to a degree, but is quickly punished by rate-limiting, which limits the effectiveness. Still it's quite fun, you can check out the code here.

TravisR's work on matrix-bot-sdk is interesting for bot or other client devs, and there is a new guide available:

A few weeks ago I mentioned matrix-enact, which uses Web Audio API to play back room history. There is a guide to how it was built, looking at the /context endpoint now available:

Half-Shot "bridged to #matrix-synapse on freenode to help folks who might be experiencing issues with their homeserver and need a IRC based support channel"

Black Hat made a cool-looking thing: "It basically shows all pictures in this room in a waterfall, with 'infinite scroll'"

Movement on Matrix URIs

Sudden interest in matrix-org/ means we're getting a lot closer to agreement on Matrix URIs. Kitsune even added support for them in Quaternion (see below).

Dept of Servers 🏢



Dendrite continues marching forward! As more attention is turned towards our fairly lengthy PR list, contributors who have not done so already are reminded to merge Dendrite's master branch into their PRs, as converting the project to go modules caused a lot of conflicts. A tag has been added to each PR that needs forward merging, visible here.

Our GSoC student cnly has been working away on implementing profile retrieval over federation as well as updating his various other PRs and would likely have a lot more if they were getting more reviews, but worry not as things look on track for that next week.

We've also got plans now! Plans for how to properly ship this thing over the coming months so look out for that soon!

Synapse 1.1.0 released

This week we shipped v1.1.0, which provides an overhaul of docker configuration, more authentication options and improved db io. It’s worth noting that v1.1.0 is the first Synapse release to drop support for Python 2 (and Postgres 9.4), this paves the way for using Python 3 only functionality.

We’ve been working on supporting soft logout, more edits and reactions support, open tracing support not to mention a complete rewrite of the push server Sygnal. We’ll be rolling out new Sygnal gradually over the next week or two.

Finally, aided by dropping Python 2 support, we’ve been putting in a bunch of work to improve Synapse in resource constrained environments. This will be a constant theme over the coming months.

Brian Ó appeared to tell us about python-matrixbot. This is a project that has existed for some time.

A Python module meant to act as a base class for a Matrix bot.
The MatrixBot class will connect to the Matrix server, start a listener on each joined room, and listen for room invites from other users. It also includes helper methods you can use to extend the functionality. It is built on the Matrix Python SDK which can be directly accessed via MatrixBot.client



koma got some improvements, based on what's learned developing Continuum, which is a desktop client based on it.

  • Make api calls suspendable functions (which are like Kotlin's flavor of async). This way, the caller don't need to worry about forgetting to call await or a coroutine being left unstarted.
  • Borrowing from functional programming, model the outcome of a call as a discriminated union, which can be either a success or a failure. The successful case is optimized with inline classes, an experimental feature in Kotlin 1.3, and wrapping is avoided.
  • Make MatrixError a subclass of HttpError, because the http status code can be handy

matrix-appservice-bridge release 1.9.0

Half-Shot was seen to exist IRL this week, he also found time for a new release:

Today we have a new matrix-appservice-bridge release 1.9.0. The bigname feature this week is a new store for mapping matrix events to remote ones, so bridges can handle changes made to sent events like reactions/threading/edits/redactions :). The reason for this feature appearing suddenly will become clear very soon.. 😈

mx-puppet-bridge (inc slack, tox, discord)

Another week, which means more work on the mx-puppet-bridge ecosystem! A new > bridge has been added, mx-puppet-discord. Soru finally added license files > (Apache-2-0) and some readmes.


  • bugfixes
  • implement optional double-puppeting (also logging into your matrix acc)
  • relate remote event IDs to matrix event IDs
  • handle edits in both directions
  • handle redactions in both directions
  • initiating conversations from matrix! Invite a ghost for 1:1 or follow a > room alias for rooms
  • bot provisioning: list users and rooms


  • add linting

They mention,

warning may contain ranting about the codebase

But that could be any room, so it seems ok to me.


Hi everyone! Myself and Cadair have been working hard on a new Slack bridge release, and we are finally ready to push out a release candidate for 0.3.

The headline features are:

  • Implement message deletion.
  • Add support for edits.
  • Add support for reactions.
  • Add support for threading (using replies).
  • Support displayname and avatar lookups for Slack bots.
  • Replace channel mentions with canonical aliases for bridged rooms.
  • Support for slack attachments (Thanks @umitalp for the initial groundwork and @Cadair for the cleanup)

The new release is having very final minute checks, and will be available at shortly.

  • Start work on chat details screen (members, change name, etc.)

Quaternion now with Matrix URI support


to push things forward on Matrix URIs front, Quaternion master branch now supports matrix:user/userid, matrix:room/roomalias and matrix:roomid/roomid URIs. For example, Quotient/Quaternion room can be opened by a link matrix:room/

This will be so much easier to use! Also:

Quaternion has got a new contributor, Roland Pallai (, who added colouring of messages sent by the local user and support of drag-n-drop of text and images on Quaternion, along with general improvements on the timeline. Many thanks!

Windows builds of Quaternion (CI and future releases) come with Qt Keychain enabled, storing your access tokens in Windows secure storage.

Spectral news

Black Hat:

A lot of improvements have been added to Spectral last week.

  1. Spectral uses QtKeychain now. Access tokens are stored in system keychain instead of in plain text.
  2. Room list's filter has a better UX(aka TabBar). Switching between rooms and DMs is now as easy as switching between, well, tabs.
  3. Notification count in system tray icon, implementation modified from nheko.
  4. Display initial sync progress. Some people have been complaining about not knowing the progress of initial sync so I added an indicator.
  5. A better room setting page. Specifically displaying aliases and changing room avatar are working.
  6. Big emojis.
  7. Typing indicator UI is tweaked and looks better.

Riot iOS

  • Reactions in e2e rooms
  • “Show all” button when there are too many reactions
  • Support edition of emotes and replies
  • Edits history (even in e2e rooms)
  • Fix joining new upgraded room through federation
  • Use via parameters to join a new room (useful in case of federation)

Riot Web

  • Allow resending edits, reactions and redactions through context menu, also better visualization of send errors.
  • Allow redacting and viewing source of edits in edit history dialog

lino "wrote a script to update riot. It also works so far, but still needs some improvements"

Black Hat has been working "to add .well-known support for libQuotient" - presumably this will come back to be used in Spectral when it's ready.

Here's Neil:

With 1.0 shipped we are now starting to take a closer look at Synapse performance more generally and this will be a theme for us over the coming months. We want to improve not only large scale deployments such as but also optimise for smaller instances.

You may have seen a few trial servers run by core team members in community rooms popping up and this is a precursor for a broader effort to make synapse more manageable on less powerful infrastructure. My own instance has been sat at a pretty steady 256MB of RAM.

Other than that, based on 1.0 feedback, we have been working on improving the Synapse upgrade path and expect to put out a new release next week containing the tweaks. Specifically this means improving configuration for Docker installs, and configuration management for sending emails.

We’re also implementing open tracing into Synapse, initially to help with e2ee debugging, but it will make tracking down strange behaviour easier more generally.

Finally we’re bringing our push server Sygnal kicking and screaming into 2019 and will upgrade to Python 3, drop gevent for twisted and update our vendor specific libraries, not mention improving the monitoring and alerting. We’ll also add in open tracing which will help hunt down push failures.

Finally finally, look out for a DAG visualisation tool written by GSOCer Eisha referenced elsewhere in TWIM - we consider this to be seriously cool, and can’t wait to start using it in anger.

Note: 1.0 is the last release to support python 2 and postgres 9.4, the next Synapse release will drop support for both, see for more.


Dendrite received a few updates this week. Notably:

  • Cnly has been implementing typing notifications support in #718
  • anoa has been fixing up the flaky sytests in #631. The team is considering moving from CircleCI to BuildKite for tests in the future.
  • Cnly has added a few issues for odd bits and bobs they’ve found around the codebase. This is much appreciated!


  • We now support building with Clang, and also GCC-9
  • Work on version 3/4/5 rooms has been underway.


This Week in Ruma:

This week was spent working on a big revamp of ruma-events, the library that defines Rust types for the "events" used in Matrix. After some discussion in, I decided to make a move towards treating ruma-events as a higher-level library. Previously, ruma-events has more or less offered Rust types that are exact representations of the JSON structures used by Matrix. However, by representing events this way, it would be possible for users to easily create values that, while valid JSON, would be invalid events according to the specification. The way we're approaching this problem is by separating serialization/deserialization of JSON from validation of events.



Jeon 0.9.0 release. It is a release candidate for Jeon 1.0.0 which complies with the Matrix stable release 1.0. Not a lot changes, just added missing endpoints and events. Also I started to work on JeonServer, a Matrix server written on java.

Jeon is a set of Java interfaces to Matrix APIs, JeonServer is a proposed homeserver.



matrix-media-repo has received some speed improvements and is generally nicer to memory when using the s3 datastore. Give it a try and leave feedback in

GSOC project: Matrix Visualisations 🎓

Eisha appeared with this terrific GSOC update:

The GSoC project “Matrix Visualisations” has made good progress during this first period:

  • The implementation of the CS API backend has been completed to properly retrieve events from a room in real time.
  • Many features have been added to the UI, here are some of them:
    • The DAG is displayed vertically, every node of the same “depth” are on the same level in the graph and each node has outgoing arcs for each of its previous events (if they have already been retrieved).
    • The node at the top of the DAG allows to fetch earlier events by selecting it.
    • Each node can have two different colors whether its “origin” is the HS the application is currently talking to or not.
    • The full JSON body of an event can be displayed by double clicking on its node.
    • It is possible to select which fields of the events will be directly included in the labels of the nodes.
  • A (server-side) backend has been implemented so that the application can directly talk to the PostgreSQL database of Synapse. You can find it on this repo.

Note that the support of the Federation API has been postponed so I could work on this Synapse database backend. The UI of the application isn’t very beautiful or well-organised yet, as the effort is focused on the backends and core functionalities for now, but improvements will be made once these functionalities will be completed.

Remember you can check TWIM from last week to get a reference on the other three GSOC projects.

Just cut a 1.2.0 release of the Ruby SDK, including fixes for timeout handling, some general code cleanup and documentation work, and a collection of getters and setters for most of the specced room state types

Dept of Bridges 🌉

freenode IRC bridge restarted

The freenode IRC bridge was restarted with the following fixes:

  • Some characters in IRC usernames (such as “|”) would cause IRC user’s messages to not appear on the Matrix side.
  • Room upgrades are now handled a bit more cleanly

mx-puppet-bridge platform

Sorunome has been working on her all-new bridge platform, mx-puppet-bridge:

This week soru has been working more on mx-puppet-bridge, together with mx-puppet-slack and the now-new mx-puppet-tox.


This is work on the underlying bridge, protocol implementations still have to do their thing

  • room name, icon and topic (was already implemented but untested)
  • ghost name and icon (was already implemented, but untested)
  • file sending in both directions (image, audio, video, file, autodetect) (was already implemented, but untested)
  • have own ghosts create rooms --> appservice bot is not needed, more invisible bridging (especially nice for 1:1 rooms!)
  • implemented 1:1 room bridging
  • implemented provisioning interface via appservice bot
  • remote -> matrix presence handling
  • remote -> matrix typing notifications
  • matrix -> remote puppet name tracking
  • matrix -> remote puppet avatar tracking
  • mx-puppet-bridge uses caching for better performance
  • Added linting


Lots of work here, smoothening things out

  • room name, icon and topic bridging
  • ghost name and icon bridging
  • file sending in both directions
  • presence and typing notifs


This is a new one! It bridges tox over to matrix...or, well, more acts like a client (as tox doesn't have multidevice). Basic chatting was already functioning with only around 300 lines of code! The node toxcore bindings seem to only include support for 1:1 chats (and not the new group chats), so only that is implemented.

  • ghost name and icon bridging
  • file senidng in both directions
  • presence and typing notifs
  • matrix -> tox name and avatar syncing

There is already substantial documentation available, and a Matrix room at

Dept of Clients 📱

RiotX (Android)

  • We are finalizing the MVP of RiotX. Many new features, along with many bug fixes this week:
    • Notifications for version with or without Firebase Cloud Messaging
    • Reply in e2e rooms
    • Change of DI tool (We are now using dagger2)
    • New settings, split into categories
    • New set of Emojis for quick reactions
    • New application icon
    • And many other little features
    • New disclaimer screen, displayed at first startup
    • New suggestion screen (based on bug report screen)
    • Min SDK version has been set to API 19 (Kitkat), mainly for security reasons, but also because we are using MotionLayout which is available only on API 18+.
  • Remaining work to do before we can release the first beta version on the PlayStore:
    • Encrypt/Decrypt attachment in e2e rooms
    • Last event display in the room list
    • Test, test, test, and fix, fix, fix :)

Integration of Matrix into Delphus


Our company, Scintillating, has integrated Riot as an end-to-end encrypted chat, video, and voice call provider for our decentralized scientific study management system Delphus. We have created a method of linking Matrix IDs with Ethereum addresses to allow scientific researchers to look up participants and create chat rooms to talk with individuals in a privacy-preserving manner.


We didn't get a Spectral update for a few weeks! Black Hat reported:

Quite a few changes in Spectral in the past few weeks. The room list filter is improved, and it only shows rooms with unread notifications by default. User can optionally hide join/leave events. Empty avatar in direct chats is fixed. Each user now has a unique message bubble background color in the timeline.

Pattle: version 0.8.0

Wilko, chief Pattler:

A new version of Pattle has been pushed to F-droid!

Although this isn't the biggest release, it's still a big step: the first release of iOS will be available! The build is currently still in review by Apple.

You can download the iOS app via TestFlight soon, join to get the link immediately when it's available!

Other changes

  • Add .well-known support!
  • Automatically update homeserver property in 'Advanced' while typing username
  • Fix messages being wrongly grouped by sender
  • Fix direct chats staying marked as direct when someone else joins

Install this release


  1. Add the following repo in F-droid:
  2. Install 'Pattle'

APK: Download from the assets of this release


If you stumble upon any issues, please report them! You can login via GitHub and, so it's really easy to do!

Follow Pattle

Follow development in!

Support me

If you would like to support me, you can now do so via Liberapay and Patreon.

I've invested a lot of money in making Pattle happen on iOS: MacBook, Apple Developer Program, and an iPhone. Pretty costly, so any donations will be greatly appreciated!

continuum updates placeholder avatars


continuum tweaked the appearance of placeholder avatars. To make most users appear visually distinct, continuum has always used colors based on checksums and usernames to generate placeholders if any user doesn't have an image as avatar. In previous versions, it always used two characters of the name. In the new version, if the username contains ideographic (usually east-asian) characters, a single character would be used. The reason is that the number of ideographic characters is vast and duplicates are less common, and most of them are close to a square or circle in shape so a single one would fit the GUI component better.

FluffyChat edges closer to E2E


Last weekend hummlbach (from the UBports community) visited me and we worked 18 hours on implementing end2end encryption. We are now able to send encrypted messages. Key sharing and decrypting will follow.

Not available in the released version yet, but join for more info. Also: 18 hours! Woah.


Quaternion received several updates recently, check out for more info.

Fractal released 4.1 dev version

Alexandre Franke:

Fractal released a 4.1 development version, which was added to the beta channel of flathub. danigm is eager to get 4.2 out soon and is trying to fix the last few bugs we want to see gone before then. He already opened a few merge requests.


  • Updated the reactions UX with a new tooltip-style interaction
  • Added edit history dialogue and other small editing tweaks
  • Riot Desktop config options (such as default HS, theme, etc.) can now be overridden for easy customisation


  • New reactions in the event contextual menu
  • Edits in e2e rooms
  • Still refining reactions and edits

matrix-enact, read-only client which performs the contents of rooms with Web Audio API

Some time ago I made a toy:

This is a read-only Matrix client, which takes the contents of a public room and "enacts" it, that is, it performs it using the Web Audio API in your browser

The original intention was to be a demonstration of what can be done with /context endpoint, but the project scope expanded a little. Hopefully people find it fun!

Dept of Ops 🛠


Slavi and his many helpers have been working on matrix-docker-ansible-deploy:

matrix-docker-ansible-deploy has seen a lot of work on bridging lately. All currently existing bridges (Discord, Facebook, IRC, Telegram, Whatsapp) have been redone in a way that makes their configuration completely playbook-managed, as well as extensible. Besides this, with Synapse v1.0 already out, we've taken the opportunity to simplify the installation instructions a bit. If you haven't upgraded recently, now would be a great time. As always, be sure to take a look at the CHANGELOG before doing so.

Update from the Matrix on Debian team

This is an update on the state of Matrix-related software in Debian

Dept of Identity 🛂

mxisd forked

Following the announcement that mxisd would not longer be worked on, ma1uta has stepped up to provide support:

I forked mxisd ( and will provide support this project. You can ask about help in a new room A new temporary name will be ma1sd (thanks Dandellion ). Due to changing maintainers I start to prepare the new 2.0.0 release and should audit code and dependencies. Also I forked matrix-synapse-rest-password-provider ( because it often uses with mxisd. Docker image, ansible support, debian, nixos and archlinux packages are temporary unavailable due to code auditing and changing maintainers.

Cos created an article detailing how to link existing unix accounts with accounts on a Synapse homeserver.

Dept of Bots 🤖



I made a Matrix bot that uses reactions to do polls! The code is available at (with a screenshot of how it works) and you can invite in your room if you want to try it out 🙂

Bot works by taking a list of emoji + responses from a user, then makes a new message event with those emojis each voted for once. In this way, you can quickly make a reaction-based poll.

reactbot, a maubot

tulir, never enough maubots:

The reactbot I announced last week has been updated to support arbitrary response content instead of just reactions. As examples, the repo now has a stallman interjection bot (ported from this and a replacement for jesaribot. Reactions as responses are still supported and the repo still has the TWIM cookie bot example too.

Final thoughts 💭

Ananace has been looking again at a release tracker they'd previously been working on. have set up an ActivityPub instance (see Not strictly Matrix but interesting that they decided to move to a federated platform.

First GSOC evaluation submissions were due this week, all four Matrix projects are proceeding well. See Eisha's update above, and the other three last week.

red_sky, nheko maintainer, was seen to say: "I know there hasn't been much activity from me lately. I was on vacation last week. I'll be getting back to work on 0.7.0 today"

The Europas awards ceremony was held at a venue next to my old flat. Small world! Small flat too.

That's all I know 🏁

This Week in Matrix 2019-06-21

21.06.2019 00:00 — This Week in Matrix Ben Parsons

Matrix Live 🎙

Matthew and Amandine talk about what we're hoping to ship in June

Dept of Servers 🏢


We have a whole lot of Dendrite news this week! First, from anoa, on the Matrix team:

Progress has been picking up this week with some of Cnly’s many PRs finally getting merged! Cnly is our resident Google Summer of Code student this Summer and has been making strides ever since. We also finally fully migrated to BuildKite for Continuous Integration (which is much quicker than TravisCI) and have implemented golangci-lint as the project’s opinionated linter (catching some bugs in the process).

As part of CI, we’ve set up Sytest for Dendrite, which grants us a loose method of keeping track of progress as we go along. Currently the only way to do so is to take a look at the testfile which holds all the tests we know Dendrite to be passing, and cross-referencing that with the list of all sytests (which isn’t actually available anywhere). We’re hoping to make some nice way of visualizing progress over time with this data (and possibly break it down into Federation/Client/Application Service categories), but this will take some time.

We’d also like to thank some new contributors that have shown up since Matrix 1.0’s release. serra-allgood contributed a fix for querying aliases when using at least one application service, while DrGlitchMX sent a PR in for some database fixes. SUMUKHA-PK’s PR to add room tags is still around and should see some love very shortly.

As far as the current goals of the project, we’re looking to primarily make Dendrite federate with Synapse, which will allow it to actually be usable for testing/basic day-to-day usage. We intend to have it done so in the next few months, so stay tuned!

Next, from Cnly, who is doing GSOC🎓 on Dendrite:

For Dendrite, the first phase of GSoC has primarily seen improvements for the existing code including bug fixes, refinements for testing, and some refactoring that prepares Dendrite for later feature implementation. Among the changes, two important ones will be the initial support for EDUs in /sync responses as well as a federation destination cache that allows for more effective federation.

In the next phase, more focus will be put into feature completion, mainly for the Client/Server API component. Since this part of work covers various still-under-construction areas in Dendrite, it is foreseeable that more progress will actually be made than proposed.


This Week in Ruma:

Work is underway to bring Ruma up to date with version r0.5.0 of the Matrix specification. Starting with the most foundational libraries and working up towards the higher-level ruma-client, this work should be done in the next week or two. The bulk of the work since the last update has been on ruma-events, adding all of the events that were previously missing, and doing a full pass through existing events to make sure our definitions match the specification.

I can't wait to see more updates out of Ruma!

Dept of Bridges 🌉

matrix-appservice-discord 0.5.1

This announcement is nearly a week old from Half-Shot, coming in right after the previous TWIM was published:

We've released v0.5.1 of the discord bridge today. It's mostly comprised of small bugfixes and features, but contains metrics support for tracking performance on the bridge.



mautrix-telegram got some bugs fixed and minor features:

  • Updated to Telethon 1.8
  • Option to limit maximum document size when bridging so it wouldn't download 1.5gb files and run out of ram
  • Made the state cache get updated when sending state events. Not doing this was causing some problems on, which has disabled echoing state events (probably for performance reasons)

Reliable Bridges GSOC 🎓

Kai is working on bridging in Matrix, mentored by Half-Shot:

The first phase of GSoC is nearing its end and progress has been made on the Reliable Bridges project.
The main focus of the work was on delivering a running implementation for the signaling of permanent errors. Work has been done on matrix-appservice-bridge together with matrix-appservice-discord. An internal version of the Discord bridge with the new feature is already running and the related PR for the bridge SDK is in the state of being completed.
The next phase of GSOC comes with new goals. First, the preparation of a MSC for the signaling of bridge errors, so that the feature can be discussed in the community and can become a part of The Spec. The second goal will be the modification of Riot Web, so that the user is notified when an error condition occurred.
There also has been a slight change of plan: The work on notifying clients when parts of the system are temporarily unavailable needs reconsideration as not even the core Matrix network itself has this capability. The way forward here should probably be a unified solution.

New TypeScript puppeting lib: mx-puppet-bridge

Soru, who you probably know from her work on matrix-appservice-discord, has started a new library:

Soru started working on a new puppeting library, for a lack of a better name it is currently called mx-puppet-bridge.
Unlike the existing puppet bridge, the focus of this one is to handle multiple users at once, all dynamically without needing to edit the configuration file over and over. Additionally the new codebase results in quite a few things smoothened out for easier protocol implementations.
Furthermore mx-puppet-bridge is written in typescript and based on travis' matrix-bot-sdk.
As protocol implementation for testing, soru also wrote mx-puppet-slack (again, for the lack of a better name). Basic message sending in both directions is already fully functional.

Exciting stuff! And all the more so for the third-person announcement style!

Dept of Clients 📱



Gomuks had a bunch of changes:

  • Added support for rendering redactions and edits (rendering reactions coming up next)
  • Added commands to create rooms, start private chats and edit room tags
  • Rendered images now don't take up the whole width
  • Improved memory usage slightly
  • Broke everyones existing caches (rm -rf ~/.cache/gomuks should help if it panics at startup)

The command for creating rooms and the image resolution limit were added by a new contributor, J. R., who is currently working on adding .well-known discovery support.

I've been having a good play with this and like it at lot!


continuum, JavaFX client


Improved support for more types of events in continuum this week:

  • invitation events are supported
  • support for events that typically appear when a room is being set up is in progress
  • events that are not yet supported are displayed with a fallback view. Blank rows in previous versions are now fixed. You could always right-click on any event to view the source, of course


Pattle, Dart client

Wilko came in with this thorough update, Pattle development is MOTORING:

A new version of Pattle has been pushed to F-droid!

This release is mostly focused on bug fixing and bug reporting! This is why I urge all users who have been having problems before to try Pattle again! Chances are that your problem has been fixed, and if not, it will be reported with more information so I can fix it!

When an error is reported, this data is sent:

  • Operating system version
  • Device model, brand, manufacturer and whether it's a simulator
  • A unique ID based on your device

In some errors the homeserver domain is logged, I will try to prevent this in the future.

This release also includes preparation for an iOS release next week!

Fixes and other changes:

  • Handle rooms that the user has left (a notice is shown that you can't send any messages)
  • Show a date header above the chat creation event (not the first known event in the list as before)
  • When an error occurs during sync, show a message, including the Exception name
  • Fix replies causing an error if the formattedBody does not adhere to the spec (thanks to Mathieu!)
  • Fix errors not showing when logging in
  • Fix loading spinner showing when checking username or logging in even if loading took less than 3 seconds
  • Fix direct chats not detected when adder after the initial sync
  • Some general syncing issues have been fixed (causing the dreaded infinite loading spinner).

To install this release, add the following repo in F-droid:

And install 'Pattle'.

Or download the APK.

If you stumble upon any issues, please report them!
You can login via GitHub and, so it's really easy to do! (Logging in via GitHub did not seem to work previously, but it will now!)

Follow development here:!

If you would like to support me, you can now do so via Liberapay and Patreon. I actually need money for the Apple Developer program, which costs 100 euros per year to release Pattle on the App Store and Testflight.

Quotient (former QMatrixClient)

aa13q is a GSOC 🎓 student, working on E2EE and mentored by Kitsune:

I'm working on my E2EE GSoC task: One-time keys uploading part is implementing currently. Draft device keys uploading is also here. The implementation follows E2EE guide:
My contribution and reports are currently here: Also, feel free to reach me via Quotient group
I'm trying to reuse Black Hat's qtolm project: -- added CMake files to include to libQuotient project, special thanks to Black Hat for his work.
Thanks to my GSoC mentors and Matrix and Quotient communities for support and solid groundwork. Long term goal is to provide modern Qt-based library to support full-featured matrix clients like Quaternion, Spectral or even to revive Telepathy IM connection manager! %)

P.S.: Maybe somebody reading this is brave enough to play with Qt-based server implementation too? :)

Riot Web

  • Updating reactions UX to match new designs
  • Continued refinements to editing *Tweaked SAS verification dialogs to behave more nicely

Also: Riot Desktop was updated on the Snap Store.

Should you want to follow the blog using your Diaspora protocol compatible account, there is an unofficial mirror of the blog at [email protected]. (disclaimer: I'm not affiliated with the account, just found it and reporting)

Final thoughts 💭

🤔 A company named "Slack" had an IPO, in which the share price closed up 50%. Slack are involved in "Instant Messaging" software and their product is known for the ability to connect to other services.

⏰ It's the first GSOC assessment NEXT WEEK. We'll get updates from all four projects, but notice that three of the projects have already provided updates above.

🤖 tulir created TWO new maubot plugins, one for translating things: Check out the bot user. The other is a "react bot",, "that reacts to messages that match predefined rules".

⁉️ Black Hat (from Spectral and more) is "experimenting with ruma-client-api and plans to create something awesome with it", Alexandre Franke (from Fractal) got a new laptop. Fox "just did [their] last java uni exercise ever and am now free from this curse, will have time to work on Neo".

🔨 This website has had a lot of polish over the last couple of weeks. We'll be focusing on the incremental improvements still needed, and also on adding new documentation. Let us know what you think we should do next.

That's all I know 🏁

See you next week, and be sure to stop by with your updates!

Matrix Live - Prof. Jon Crowcroft, Foundation Guardian 🎙

Matthew & Amandine talk with Prof. Jon Crowcroft, one of the new Foundation Guardians!

Matrix 1.0

The big news this week is that we declared ourselves to be out of beta. You'll want the full post for all details, but here's a taste:

We are very excited to announce the first fully stable release of the Matrix protocol and specification across all APIs - as well as the Synapse 1.0 reference implementation which implements the full Matrix 1.0 API surface.

This means that after just over 5 years since the initial work on Matrix began, we are proud to have finally exited beta!! This is the conclusion of the work which we announced at FOSDEM 2019 when we cut the first stable release of the Server-Server API and began the Synapse 0.99 release series in anticipation of releasing a 1.0.

As part of the 1.0 we also announced the Foundation.

For the full update on the Foundation, please check out the new website content at which should tell you everything you could possibly want to know about the Foundation, the Guardians, the Foundation’s legal Articles of Association, and the day-to-day Rules which define the Open Governance process.

Thanks to everyone who has stuck with us along the way to make this possible.


We released Synapse 1.0.0 this week to coincide with Matrix 1.0. As a release Synapse 1.0.0 focuses on security and stability which in turn builds a firm foundation for the performance improvements that you can expect to see over the Summer. Read all about it here.


We have not one but two working end to end demos of device cross signing! This is going to be huge and is key step towards being able to make Matrix e2ee by default.

Cross Signing Demo

Additional Treats

But wait there's more! Pantalaimon not only provides a way for clients and bots to participate in e2ee rooms, it now provides the ability to search. Checkout this (religious themed) demo.


Pattle is going great guns at the moment. Here's Wilko:-

A new version of Pattle has been pushed to F-droid!

  • Add ability to create group chats!
  • Show chat creation events ('Wilko has created this group')!
  • Show emote messages correctly!
  • Handle display name changes! Display names of messages will now be as they were at time of sending.
  • Don't show invite and join events in direct chats This is only happens for the two initial users in the direct chat. If someone invites someone else to the direct chat (trough another client), the invitation will show up in the timeline.
  • Use the timeout parameter while syncing. This means that receiving new messages should be way quicker! (Thanks Mathieu!)
  • Store messages retrieved remotely (thanks Mathieu!) This means that scrolling up in a chat will be faster now, because the messages are cached.
  • Always show a date header above the oldest event
  • Show replies correctly in chat overview
  • Show sent state icon next to own message in chat overview
  • Show newly joined rooms at the top in the chat overview
  • Use a bit bolder font for chat names in overview To install this release, add the following repo in F-droid:

And install 'Pattle'.

  • Reactions now instantly cancel when you redact them
  • Redactions now instantly redact when you send them
  • Released v1.2.2-rc1 (up for testing at - this release includes room breadcrumbs being out of labs, some fixes for inviting by email, fixes uploads in chrome canary / firefox nightly, config file validation, some fixes for the new emoji font and lots of other bug fixes.


Jimmy reports that

New versions of the ruma-api and ruma-api-macros libraries were released, and work is underway to bring ruma-events up to date with client-server spec r0.5.0


TravisR has this to say: >Both matrix-media-repo and Dimension have been updated to handle federation certificates. Please update, as you would for Synapse 1.0.0


Alexandre Franke has fixed the regression he found last week. The team also did a bit of housekeeping with a few dependency updates.


Half-Shot reports that:

I wrote a bot to control ansible playbooks I'm informed such a thing already exists as an ansible module, but I failed to realise that and wrote a independent one in TypeScript.

tulir reports that:

I made a simple reminder maubot: It's available at

For room admins wondering if they can upgrade their rooms to v5, I made a bash script that checks all the servers in a room and prints a nice summary of the number of servers and members on each version:

Atreatis reports that:

Currently grin is building a backend for that will collect data and push statistics every hour to our website. Next to that I wanted to push forward that me and several others are looking into building a Code of Conduct that should help every new and existing home server. This code of conduct will be build and curated from scratch in-order to help and support the network or any general project.

Pneumaticat has this to say:- >My homeserver ( is open for some public registration! Also on Atreatis's

They promise 'One nine of uptime guaranteed, or your money back' which sounds pretty like a bargain.

Dept of Spec 📜

We are sooo close to Matrix 1.0. So close! The PR which announces the arrival of v1.0 exists already.

TravisR said:

Work towards 1.0 is progressing nicely - still on track for a Monday release! View our progress at

Dept of Servers 🏢


Neil, who oversees the creation of Synapse:

Quiet week, not much happening, the only real progress has been shipping a Synapse 1.0 release candidate :) Joking aside we’d really appreciate your help in testing it ahead of the full release next week. Get the RC here

Also friends don’t let friends operate a Synapse install without a valid certificate on the federation API. Post 1.0, servers that are not compliant will be locked out of the federation. While the copy needs updating to reflect 1.0’s imminent release, our handy FAQ ( has all the details.


Construct, a C++ homeserver has been doing testing this week:

I'd like to give special thanks to Ddanyspin97 (Danilo Spinella) for working on building construct with the musl C library so we can enjoy extremely small VM images, as well as Black Hat for building on Alpine linux also using muslc and Thomas Lewis for starting work on the FreeBSD build.


Ruma, a homeserver written in Rust, has a new surge of activity following the Rust language syntax developments last week. This Week in Ruma received it's first edition in ~6 months!

Jimmy, project lead:

the ruma homeserver is now targeting stable rust, which means the entire project is now on stable rust

New project: load balancer for synchrotron workers


[I] wrote a proof-of-concept load balancer for synchrotron workers....well, proof-of-concept because it isn't tested much, yet!

It routes users to synchrotrons based on their user ID to maximize performance, as per worker docs and, if a synchrotron catches fire it'll also automatically start shuffling workers around.
The repo can be found here, for support just poke soru wherever she is

Contributions are welcome!

Join the newly created room at to discuss.

Dept of SDKs and Frameworks 🧰

Ruby SDK


Just released version 1.1.0 of the Ruby SDK, which includes a few more and improved CS API endpoints, better room alias handling, lazy loading of join rules and guest access, and the forgotten - oops - handling of room avatars.

And released version 1.1.1 of the Ruby SDK too, fixing another embarrassing mistake with not including the S2S API methods correctly, which lost the server version retrieval method (The only currently implemented part of the S2S API)

Dept of Clients 📱


Are you in the know about Matrix? If not, prepare to learn about RiotX, a completely re-written Matrix client for Android. This new version has a Kotlin SDK.

Benoit, from the team:

Many things to announce this week on RiotX:

  • Crypto is starting to work! We can now decrypt message and send encrypted messages. The whole feature is not implemented yet, but we will merge the PR at the beginning next week before going further. Thanks François for the great work!
  • On the timeline, message composed by only emoji are now displayed bigger (as in other Riot clients)
  • We can now see details and actions of each message, including state event.
  • We can also see the detailed list of reactions for a particular message, and reaction display rendering has been improved. More details of what has been improved by Valere can be found in this PR description:
  • Local echo on message edition has been improved
  • The 3 main themes has been implemented (Light, Dark Black). Status theme is still there but has not been tested yet. There are still some little issues which will be fixed in the next coming days.
  • The new Home is on develop, composed by a catchup tab, a direct message tab and a group room tab. The drawer is now used to display the groups hierarchy.
  • A debug signature has been added to the git repository, so the APK built by buildkite can now be installed and replace a previously installed APK.

There is still lots of work to do, but we are quite confident to deliver a first alpha version of RiotX to a larger audience at the end of June.

We've heard about Famedly before, and here they are with an announcement about their new client:

After some months of work our app 'famedly talk' is now able to send and receive messages. We are now concentrating on implementing the most important functions in a stable manner.

fix some missing avatars and names of rooms. Normally continuum saves all useful data to disk when syncing, but the previous version missed some of it, the newer version will query the server for the missing pieces


This week in Fractal: Alexandre Franke noticed nightly was broken on all three of the computers he was using it on. He bisected and found out when the regression was introduced, but still needs to figure out why it broke and how to fix it.

The symptom is syncing forever on startup and never actually syncing. The commit introducing the borkage is this one.

matrix-appservice-irc 0.12.0 released


matrix-appservice-irc got a release 0.12.0. This is a smaller release, as it's based upon 0.12.0-rc2 which was released back in March (when exams hit). In the meantime, working towards a speedy 0.13.0 release :)

Changelog for 0.12.0:

The bridge now supports upgrading rooms, and will follow room upgrades to the new room.
Added support for the RoomLinkValidator, which allows admins to manually configure rules about plumbing rooms.
A dockerfile is now included.
Add support for "feature flags", allowing users to dynamically enable/disable bridge features for their account.
Add command "!bridgeversion"

High-level plan for 0.13.0:

Fix the most serious P1 bugs like not dropping messages, handling PARTs better, dropping support for older versions of node, and generally better UX.

I launched as a place to collect information, lists, guides and manuals related to matrix. I hope as a community we can work together on this to create a central knowledge base for the matrix protocol.

Final thoughts 💭

I spent so much of my week migrating to a great new design (from Nad), and am really happy with the result. I'm also really happy with Gatsby, the SSG we've chosen. All these things have flaws but overall it works well.

That's all I know 🏁

See you next week, and be sure to stop by with your updates!
