Decentralized Systems and Network Services Research Group output

Florian told us:

The article of my research group Decentralized Systems and Network Services Research Group from the KASTEL Institute of Information Security and Dependability and me, Analysis of the Matrix Event Graph Replicated Data Type, was published in the Open Access journal IEEE Access! 📰 🥳 Open Access here means that the article is freely available for you to read, under CC-BY.


In layman's terms, we showed that the Event Graph provides a strong form of eventual consistency even when new events are applied in arbitrary order. In addition, this consistency guarantee can still be povided even if all other servers in a room are malicious, which is unexpected compared to the honest majority required for the usual Distributed Ledger Technology. We also looked at the problem of “If servers randomly select at which parents at the bottom of the Event Graph they append new events, and the number of parents for an event is limited, how can you be sure that the Event Graph does not grow arbitrarily wide?“, which is something that puzzled me since the beginning of my Ph.D. two years ago. It is easy simulate a given setup and see that the width shrinks really fast, but it is also easy to see that arbitrary growth has a likelihood larger than zero. As this was astonishingly hard to grasp mathematically, we were very happy that we could recruit Prof. Dr. Norbert Henze from the Institute of Stochastics as co-author to provide evidence that you can expect the Event Graph to shrink to a normal width quite quickly.

Let me quote parts of the abstract for some more technical details:

[…] By comparison with traditional decentralized communication systems, Matrix replaces pure message passing with a replicated data structure. This data structure, which we extract and call the Matrix Event Graph (MEG), depicts the causal history of messages. We show that this MEG represents an interesting and important replicated data type for decentralized applications that are based on causal histories of publish-subscribe events: First, we prove that the MEG is a Conflict-Free Replicated Data Type for causal histories and, thus, provides Strong Eventual Consistency (SEC). With SEC being among the best known achievable trade-offs in the scope of the well-known CAP theorem, the MEG provides a powerful consistency guarantee while being available during network partition. Second, we discuss the implications of byzantine attackers on the data type’s properties. We note that the MEG, as it does not strive for consensus or strong consistency, can cope with n > f environments with n participants, of which f are byzantine. Furthermore, we analyze scalability: Using Markov chains, we study the number of forward extremities of the MEG over time and observe an almost optimal evolution. […] With the properties shown, a MEG represents a promising element in the set of data structures for decentralized applications, but with distinct trade-offs compared to traditional blockchains and distributed ledger technologies.

Synapse is a popular homeserver written in Python.

callahad announced:

Hey, it's Friday!

We released Synapse 1.28 yesterday, with the bulk of effort going into stability improvements and bug fixes, and an emphasis on further improving social login.

We're also working to more clearly communicate our prioritization of issues, starting with documenting our triage and labeling process for the core Synapse repository on GitHub.

(Still very much a work in progress, but starting to shape up nicely.)

We're also on track to maintain our fortnightly cadence of Release Candidates, with 1.29.0rc1 due out in just a few days. I look forward to telling you all about it next week!

Homeserver Deployment 📥️


Ananace offered:

Another week, another bump of the Kubernetes chart and image of Synapse (to 1.28.0), still haven't had time to fix it to be image agnostic - the Synapse team is just developing far too fast.

Dept of Bridges 🌉


Eric Eastwood announced:

We've added a "Chat via Matrix" button next to the join button in a Gitter room so you can jump straight into Matrix and start chatting that way. We've also added a link in the chat header so you can switch off to your favorite Matrix client at any time.


New LINE messenger bridge

fair offered:

matrix-appservice-line: A bridge for LINE messenger based on running LINE's Chrome extension in Puppeteer. Based on tulir 's mautrix-amp, as per Eric Migicovsky's suggestion 🙂

Currently very rough around the edges, but message sending & receiving in 1:1 chats works, as does conversation syncing & backfilling.

Repo: git://

Dept of Clients 📱

Neochat 1.1

Carl Schwan announced:

We released NeoChat 1.1 containing 2 months of new features and bugfixes. Most notably message editing, sticker events support, rewritten login screen, SSO support and more commands. Check it out at


In addition to the 1.1 release from earlier, aa13q added support for fancy animation for the 🎆, 🎉 and 🌨️ emojis. This feature can be disabled.


aa13q shared this video too!

neochat pinephone poorly recorded effects demo 🙂


Nheko is a desktop client using Qt, Boost.Asio and C++17. It supports E2EE and intends to be full featured and nice to look at


Nico ( sent a teaser image firest, then added:

As seen from the image, you can now share your screen. This currently only works on X11, since there are no cross platform APIs for that, so look out for that, if you run into issues.

Jedi18 also polished the UX a bit more and fixed bugs, so registration should now work properly again and leaving or joining rooms should place you in the right rooms after that. We also fixed some inconsistencies, where text could be misaligned, when writing long messages.


kitsune reported:

Version 0.0.95 beta4 is out, with significantly better Markdown support (code fences work now, and the overall formatting is better), further improvements to the shuttle dial and other smaller fixes. The release notes and some packages are at their usual place at GitHub; the Flatpak is also coming real-soon-now.

No (or almost no) changes in strings are expected before 0.0.95 from now, so translation contributions are very welcome at Lokalise. German, Polish and Spanish translations are quite advanced but need just a few more entries; the French translation is just about half-way; and there are many prominent languages not even started. You can help!

Dept of SDKs and Frameworks 🧰


kitsune reported:

libQuotient 0.6.5 is out, featuring fixes in rich replies handling and the updated Matrix URIs support, as per the latest iteration of MSC2312, enabling shorter, nicer Reddit-style URIs such as matrix:r/

libkazv (and the Kazv Project)

tusooa offered:

libkazv is a sans-io C++ (gnu++17) client library

built upon lager. Along with it there is kazv, a kirigami/qml client, and a

forward bot between matrix and tencent qq. Talk to us on


In the past (how many?) weeks we ("tusooa and her longcat," we hope someday we can

remove this annotation :P):

  1. Released libkazv 0.1.0 and matrix-tencent-forward-bot 0.1.0.

    Those are stable enough to run as daemon, at least for days.

  1. Added related ebuilds to the overlay.
  1. Implemented streaming uploads for libkazv.
  1. Made matrix-tencent-forward-bot support directly forwarding images

    to the matrix room.

Opsdroid 0.21

Cadair reported:

opsdroid is an easy to use chatops framework with excellent matrix support.

0.21 Release

This week opsdroid 0.21 has been released, it's an incremental release but includes a couple of nice matrix related features and fixes. The highlights are:

  • Support authorization by access token in addition to user name and password for the matrix connector. #1707.

  • Fix parsing a sync response with more than one message in it. #1715.

  • Minor fixes to the matrix documentation. Thanks to @anoadragon453 @xDiesel76 for these.

For a full list of the other changes see the release notes.

If you have any questions or want to get involved come say hi in, raise an issue on GitHub and checkout the docs.

Caridina, Crystal library for Matrix

erdnaxeli said:

Caridina, a Crystal library for Matrix, got some new releases, which bring it to v0.10.2. It now supports the last version of Crystal (0.36.1) and redacted events, which I discovered the hard way were making the lib crash. Internally a big part of the lib was rewritten using macros, which makes the code a lot clearer but the API doc too. Thanks to Ruma actually for giving me inspiration about implementing events using macros.

Again, if you like Crystal and want to write some matrix bot, this library might interest you. Feel free to open issues about bugs or feature requests! There is now a room to talk about it.

Dept of Bots 🤖


select announced:

So I had a minute to release my open q&a bot taavi.

I always wanted to write a chatbot that does cool things, so checkmark for that one on the list. In addition to that I recently failed a job interview. For their technical skill test (I did not fail this :P), I got a task for which I learned how to use puppeteer, then saw a post on reddit about Tuxi and together with my previous project that included Matrix (Audius), I knew what I had to do: create Taavi.

I have created this bot as a "weekend project", litteraly one day for the code and one day for documentation. Surely it's far from perfect but I don't have any big plans with it so far… If you think I should add some features, create an issue and let me know. I could imagine adding other websites / services to it like, do you have any ideas?

I gave my daugther the task to choose a name for a bot, that can anser any question in the world, and she came up with Taavi, nice!

JCG said:

Not sure if TWIM worthy, but here's a nice article about the recent flood of people migrating away from whatsapp, and why people should've migrated to matrix instead of Signal.

(In German)

There is also a sympathetic response that has been discussed on HN.

Seirdy said:

i've been getting some feedback from other matrix users on a blog post i wrote that outlined a few concerns I had about the Matrix ecosystem and steps for improvement. idk if it'd be relevant in TWIM, but I noticed that "Final Thoughts" sometimes linked blog posts so I thought I'd share:

Spec Core Team

The Spec Core Team has spent this week working on getting MSC2312 (Matrix URI Scheme) over the line, which is really exciting! Otherwise the team has been reviewing MSC2304 (knocking).

New Spec Platform

Work is currently underway in migrating to the new spec platform. A PR for updating the CI of matrix-org/matrix-doc to build the new spec is up, and an equivalent for matrix-org/ should be up next week.



sorunome said:

Soru has been working on experimenting with / designing a way to improve push systems within the matrix ecosystem, so that ideally clients can display full event contents in a notification and dispose of specific push notifications without the need for any extra HTTP calls. This lead her to making MSC3013 (encrypted push), so that no gateway is able to read event contents pushed down to the client and MSC3014, so that the client can know which rooms have been read on other devices, allowing them to dispose push notifications.

This is more than just MSCs already, soru already got encrypted push in a patched synapse and a patched fluffychat working locally, and it is working super great!

Dunno soru is just really excited about this somehow >~< 🦊

Hedwig: push gateway

krille reported:

Let's talk more about Hedwig: This is a push gateway for matrix and an alternative to Sygnal. Hedwig is completely written from scratch in Rust (Yes! Rust!) and offers the basic functionality to forward matrix push notifications to Firebase Cloud Messaging. That's it. Nothing more. It is intended to be as lightweight as possible and so it is very fast and stable. Just change a simple config.toml file and run the binary. There are docs for how you can configure a proxy in Apache2 and an example systemD service file. Currently it only supports event_id_only formatted notifications but maybe, in the future, we expand this functionality.

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander reported:

This week we released Dendrite 0.3.10, and have committed a couple more fixes to master:

  • The database is now only queried for remote servers once in /send

  • The oldest cache entries are now gradually evicted, saving a small amount of memory

  • The destination queues in the federation sender are now not stored forever, saving some memory

  • A bug where a non-excluded event could be accidentally excluded from /sync has been fixed

  • Some dependency fixes have been merged

Sytest compliance:

  • Client-server APIs: 60%

  • Server-server APIs: 82%

As always, feel free to join us in for general Dendrite chat or for development discussion.


Synapse is a popular homeserver written in Python.

callahad reported:

Synapse 1.27 is out, and you can read all about it on the Matrix Blog! This is the version that powered FOSDEM, and we're super proud of it. Especially the much improved support for multiple social login providers, which debuted at FOSDEM and is now enabled on

In addition to all the performance, stability, and social login improvements, there are two important things to note:

  1. If you use SSO, you will need update your configuration before upgrading; please see the link above for details.
  2. We were unable to build Docker images for ARM platforms in time for this release, and will not build images for ARMv7 in future releases.
  • To avoid unexpected breakage, we have not updated the latest tag on Docker Hub for this release; if you want Synapse 1.27, you'll need to specifically reference the v1.27.0 tag.

  • Images for ARM64 (and an updated latest tag) will return with the next Synapse release.

It took us a bit longer than usual to get 1.27 out the door, so we're also pleased to announce that 1.28.0rc1 is also now available, and we expect to release it early next week. Keep your eyes peeled for more on that next week!

Homeserver Deployment 📥️


Ananace announced:

New chart versions have been pushed for Element 1.7.21 and Synapse 1.27.0.

The rejiggering to allow arbitrary images for the Kubernetes chart got delayed due to lack of time, but 1.27.0 should hopefully be the last version with that limitation.

Nio is a client written with SwiftUI

kilian offered:

Nio has seen some great improvements since the last update, mostly thanks to gaining a new main contributor \o/

  • History loading now works (seems like a rather essential messenger feature 😄)

  • New conversations can be started (with a slick UI)

  • There's a preliminary (but well-working!) build for macOS on Catalyst

  • As a first step towards E2EE support Nio can now participate in encrypted sessions while running

  • Many new translations (thanks to all the contributors on!)

  • Lots of additional bugfixes and improvements

Join us in for more details 😊


FluffyChat is a cute cross-platform matrix client. It is available for Andorid, iOS, Web and Desktop.

krille said:

FluffyChat 0.27.0 is out. Not with the new design but with some minor design improvements like the return of the presence list top bar (or whatever you would name it!). Also this release brings a lot of bug fixes, working bootstrapping and the switch to our new Push Gateway (in Rust) we have invented inside of Famedly. You can find it here:

FluffyChat on Pinephone

Lukas Lihotzki said:

FluffyChat runs on the PinePhone (Flutter Linux ARM64). I've built it with flutter master on the PinePhone itself, because cross-compiling is not yet supported. Currently, Flutter Linux on the PinePhone only works with X11. It crashes with Wayland.

I am on the brink of buying one of these!



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

Nico ( told us:

We had a fun week this time. Today I tested trilenes screen sharing code, which seems to work pretty well on X11, although it only shares the full screen atm. I expect window sharing to land next week though. We also ran into some issues with enabling optional SSO login, which locked some people out of their accounts, since Nheko preferred SSO login in that case... This is now fixed and in such cases you will be offered both login flows.

Jedi18 also added a room name completer, which means you can finally complete aliases when typing them! The room settings were also ported to Qml and now actually show the room topic. Apart from that there were various UX fixes here ad there, like hovering actually working properly now, emote messages formatting correctly in notifications and more. We also adapted the matrix: uri support to the latest changes, although the MSC is a bit volatile atm, so it may need some more adaptions over time.

I think that's all, have a nice weekend everyone!


Bruno announced:

I'm back working on Hydrogen, and started to tackle logging to be able to diagnose problems better. I've opted for a structured log format in JSON that gives a tree of log nodes for an entire operation (e.g. sync, or sending a message, ...) which will be more compact and should also be easier to find patterns in than a pure line based format. I had hoped to get that out in a release by today but didn't get as far as I hoped, so should get released early next week.


Yes! Hydrogen progresses!


Neil told us:


  • Social Login

    • Social log-in has shipped to, we are seeing about 40% of new users opting for a social method. Next up will be landing some robustness improvements as well as automatic avatar import.
  • Spaces

    • We are aiming to get a basic version up and ready over the next few weeks. The idea is to have something behind a labs flag that will work for Spaces containing public rooms only. After that we will think about more complex cases such as Spaces containing private rooms.


  • Fix for crash on Android caused by VoIP tiles

  • Design updates on iOS for in-call view and dial pad

  • Couple of tweaks to web that may help 1:1 call connectivity


  • Element 1.7.21 was released on Monday (15 Feb)


  • Element 1.2.1 was released on Friday (12 Feb)

  • We now use XcodeGen to generate Xcode project files. Please check new instructions to build the project. It is only on develop for the moment

  • We made an update to libolm so that it accepts an external pickle key to encrypt its data when serialising it. Element-iOS uses the Keychain to provide this key.

  • We started to review and merge pending PRs in our repos but we still have work. Thanks for your contributions and patience


  • We are preparing the release 1.1.0 which contains the work on VoIP

  • This release will also contain a lot of bug fixes

matrix-docker-ansible-deploy: Synapse workers

This Ansible playbook is meant to easily let you run your own Matrix homeserver.

Slavi told us:

After lots and lots of work (done over many months by Marcel Partap, Max Klenk, a few others from the Technical University of Dresden, Germany and various other contributors), support for Synapse workers has finally landed in matrix-docker-ansible-deploy. 🚀

Learn more from our changelog announcement.

matrix-docker-ansible-deploy: GroupMe bridge

Slavi returned to say:

Thanks to Cody Neiman, matrix-docker-ansible-deploy can now install the mx-puppet-groupme bridge for bridging to GroupMe.

This brings the total number of bridges supported by the playbook up to 18. See all supported bridges here.

To get started, follow our Setting up MX Puppet GroupMe docs.

tntclaus announced:

Collection of Ansible modules to manage Matrix Homeserver instance. Only tested with Synapse but may (partially) work with the other Matrix Homeserver implementations.

Provides modules to manage users, rooms and communities.


jojo said:

synadm is growing! Pull requests have been submitted, issues been raised, bugs fixed and quite some user community seems to have evolved around it as it’s regularily mentioned on

Since it’s first announcement on TWIM in December, notable things happening in the project are:

  • Massive internal overhaul, tidying up and refactoring

  • Media Admin API support

  • Make Room Admin API support

  • Delete Group (community) API support

  • 4 availalbe output formats (json, yaml, pprint, human)

  • Python requests debugging switch

  • Textual Error responses of Synapse now showing in output

  • Licensed under GPL-3

Have a look at the latest release notes for a complete list of new features and fixes:

Thanks a lot to contributors @hpd, @kaiyou, @schwindp, @aaronraimist and @rht! Keep those PR's and ideas coming! You have been a great help!

Next features on the roadmap are "Purge History API", regular matrix client calls support and login as a user. Help me prioritise features by raising an issue:

Still, I am basically a one man show, and certainly any contributions are warmly welcomed! Even as a non-programmer you can help by keeping the implementation-status list up to date. If you find an admin API missing, please take a minute and use the integrated edit functionality github provides and add it to the list: It helps contributors to quickly find out what feature they could code!

I am also thinking about finding people who'd like to join the team, code new features and help maintain codebase, review PR's, get push access and so on. Spread the word! Join!

Final Thoughts 💭

Nico ( offered:

Oh, and maybe as a side note: Since Steam voice chat failed me one too many times now, I now use Nheko for voice chat, if I just play with one other player. It is more reliable and most people I play with do have a voip capable Matrix client installed!

Using own product 😀 👍

Famedly in the media

Nico ( announced:

Famedly (Matrix based application for German hospitals and clinics) seems to be getting positive feedback so far:

Article in German, but my favourite parts are:

  • They used the word "Anti-Datenkrake" to describe how data is handled in the application, which basically is a metaphor for Famedly being the opposite of the usual corporations trying to pry their tentacles into everyones personal data. See also:

  • They actually use [matrix]–Protokoll to refer to the Matrix protocol. The open and standardized Matrix protocol seems to be a big selling factor.

  • No MSCs are in FCP.

New MSCs:

Spec Core Team

Some chatter about the MSC2403 (knocking) as FCP has been proposed. Otherwise work on MSC1772 (Spaces) as that nears production and some encryption work with MSC2874 (single SSSS).

The team is carefully debilitating MSC2997, which spurred out of a conversation during FOSDEM2021. What sizes to include? What font to use? What colour do we paint this bike shed? All incredibly complex questions.

New Spec Platform

Will Bamberg has done an incredible job with getting both an entire redesign and an internal refactoring to the Matrix Spec. Remaining work includes ironing out some remaining minor blockers (,, merging changelog representation with respect to the current idea of a global Matrix Spec version number ( and then finally hooking up all the CI/CD to deploy it all (my job!).

We're planning to present the new spec on a new domain; running it in parallel with the old design for a bit before eventually retiring the latter.


Dept of Servers 🏢


grin shared this note from Jason:

This week in Matrix Construct added Application Services support. I've been using the Mautrix Telegram bridge on a daily basis, and it's been a pleasure to develop with. Expect more bridges to be tested in the coming weeks. I'll also be working on completing the documentation for how to setup a bridge in Construct. Just to give some insight: The server has the ability to manage all of your bridges as sub-processes. In any client, just create a room for your bridge and enter its configuration there. Voila! The bridge's console appears right in that room and can even highlight you about errors!

Join us at to learn more about bridges and lend a hand.




Synapse is a popular homeserver written in Python.

callahad announced:

We survived FOSDEM! Last week was relatively slower in Synapse land as we paused to catch our breath, but we do have news!

First, releases. Synapse 1.27.0rc2 is out now (changelog), and we anticipate a full 1.27 release early next week. This is basically the branch that FOSDEM ran, so we think it's a good one.

Second, keeping with our biweekly development cadence, the first 1.28 release candidate is due out midweek next week, so keep your eyes peeled for that. Given FOSDEM, most of our recent focus has been on stability, bug fixes, and social login. We hope to knock your socks off with more ambitious features soon. 😉

Nico ( announced:

We just landed basic support for edits. Which means edits are now applied to the original message instead of showing the fallback and you can edit your messages. You can also change a text message to a video (or the other way around) or change, who you replied to, but the latter fails to render in some clients properly, so be aware of that. Edits also send a secondary relation format, which makes handling edits easier, but I still haven't written up the MSC for that... The UI is not final yet and you can't show edit history yet, but apart from that it may or may not work fine.

There were also a lot of bugfixes like broken kerning in some cases, improved focus handling when clicking buttons in the timeline, Duplex devices should now work in calls, notifications now work on Haiku and a few more.

Now please stop asking for edits! :D

Cos discovers the /addwidget command in Element Web

Cos offered:

Public service announcement: Widgets are awesome. You can use /addwidget <url> in Element Web to add any web page in a iframe to the sidebar of Element Web. They get default name "Custom Widget" but you can rename them from /devtools menu. Very useful for group calendars, status pages and other info related to Matrix rooms.


Neil announced:


  • Social Login

    • We’ve concluded most of the development on Social Login, and tested it last weekend on the FOSDEM deployments. We found that over 50% of new accounts used it to register! We’ll be deploying Social Login to in the near future after polishing some final pieces on iOS.
  • Spaces

    • We’re iterating on the user experience for Spaces, first focusing on setting up, sharing and joining public spaces.


  • VoIP branches merged to develop on iOS and & Android - please test voice & video calling if you have the android develop build, or testflight for iOS will be coming soon. More complex scenarios with multiple devices are particularly useful to test, eg. do other devices stop ringing when you answer on a different one?


  • 1.7.21-rc.1 is now available at, including:

    • Fixed screen sharing in VoIP calls

    • Added window vs. full screen sharing option in VoIP calls

    • Fixed event permalinks to show link text instead of a room pill

  • 1.7.21 planned for release on Monday (15 Feb)

  • Element Desktop nightly builds are now using Electron 11

    • Please report any issues you notice so we can address them before the next Element release


  • 1.2.1 has been submitted to Apple. TestFlight should be available from tomorrow:

    • All new VoIP stuff described above

    • Handle User-Interactive Authentication for delete device and adding user 3pid.

    • Improve grace period management and setup Cross-Signing after login if possible when using SSO.

  • XcodeGen integration into the Element-iOS codebase is almost complete. From next week, we will not have merge conflicts on the pbxproj files. This also means better control on build settings.


  • Initial sync work improvements: performance is far better regarding RAM usage and stability (especially true for large accounts), though duration is still a concern.

  • Started working on running integration tests via CI.

  • 1.0.17 released, fixing a join over federation bug. Expect 1.0.18 next week.

MTRNord offered:

This is a super early announcement.

As now Spaces exist and are kind of testable if you know how I went ahead to plan organizing my 200 rooms I currently have into spaces and realized soon that I will have A LOT of nested Spaces.

So I am now starting to write a tool to generate these spaces easily from a folder structure and exporting them.

You may ask why not a yaml or json format: Simply to more easily allow forking of existing collections. A folder structure is much easier to do a diff over in git than file content.

Feel free to join for discussions or have an eye on where at the time of writing this only an example of the spaces folder structure exists.


MTRNord reported:

Small update time:

We are currently starting to add some documentation to it over at

It at time of writing still very barebones but over the next few weeks the goal is to add the Code of Conduct as well as a server admin guide on how to use this.

matrix-appservice-irc sprouts a book

Half-Shot said:

Hi folks! I'm happy to say that after many years of fielding IRC bridge support questions, the bridge team has now written the book on it. A markdown book! Using the latest mdbook tech we've written a draft of a usage guide and a server administration guide for the bridge and would value feedback on how we can make it better. This could be typos that I have strewn about it, or suggesting new content.

Dept of Status of Matrix 🌡️


FOSDEM is happening this year, regardless of pandemics or anything else! Actually FOSDEM in my experience is a huge super-spreader event even in normal years, so it may be refreshing to know that this year it will be fully virtual, and hosted using Matrix and Jitsi!

Matrix have several relevant talks happening:

Plus, there is a bonus talk from Brendan:

  • Mental health and free software Sunday @ 13:50 (in which Brendan talks about mental health issues in the context of working on free software, which may or may not relate to people, though certainly not me, pinging him at all hours to ask about customer integrations and features)

Plus, perhaps the most important part of FOSDEM: FOSDEM 2021 Matrix T-Shirt (Limited Edition) is now available

Conduit is a Matrix homeserver written in Rust

timokoesters told us:

We're coming closer to correct federation every day! Currently we are reviewing and improving Devin R's MR and looking for mistakes, we will be giving it a try soon.

Meanwhile I worked on:

  • Push rule settings, making it finally possible to mute rooms

  • Appservice compatibility, I'm currently trying to get the mautrix-hangouts bridge to work

  • Optimizations, incremental sync in big rooms (rooms with >3k members) went from 1.3s to 13 ms, (100x improvement)

Thanks to Famedly and everyone who supports me on Liberapay or Bitcoin!


Synapse is a popular homeserver written in Python.

callahad said:

FOSDEM is tomorrow! We're all very excited to be powering the homeserver, and we hope you'll join in over the weekend.

Earlier this week we released Synapse 1.27.0rc1, though the final release is currently blocked on resolving a regression in Synapse 1.26 (#9264) which could cause logins to fail if your public_baseurl was unset in your Synapse configuration. The workaround is to ensure that value is correctly set for your deployment.

Otherwise, we're quite excited to get 1.27 out the door, as it:

  • Solves an issue (#9172) where federation senders could take many minutes to catch up after restarts.

  • Contains countless improvements to our support for social login methods, many of which will be live for FOSDEM users this weekend.

We've also included the usual host of bug fixes and Admin API additions, but more on those when the actual release happens. You can preview the release notes on GitHub.

See you at FOSDEM!

Dept of Bridges 🌉


Tulir announced:

My iMessage bridge is starting to be usable now. Text and files work in both directions and tapbacks and replies work iMessage->Matrix. Currently it only supports running on a Mac, the iOS option will come later. The bridge doesn't require opening ports to the Mac, it uses a simple proxy that turns the usual HTTP appservice transactions into a websocket instead.

The bridge itself can be found at and the websocket proxy is at The Matrix room is


Tulir told us:

I made the first release for mautrix-signal. No particular reason, but it's v0.1.0 now. Recent changes include:

  • Better profile syncing (Signal profile names should sync when restarting)

  • Support for Signal profile avatars

  • Support for bridging stickers from Signal


Eric Eastwood said:

FOSDEM is happening this weekend! Come see our FOSDEM talk in the Real Time Communications track on Saturday around how we made Gitter speak Matrix and how you can add Matrix support to your own app:


We're also working on MSC2716 to support backfilling the massive archive of historical messages on Gitter over on Matrix. We're prototyping the MSC on Synapse and have a suite of Complement tests to verify that the homeserver implementation is working according to the specification.

matrix-appservice-irc reaches 0.24.0-rc1

Half-Shot said:

Another release! Wow. We're also testing 0.24.0-rc1 which has quite a few big ticket items this week. Off the top of the list is a new command to !plumb rooms dynamically in admin rooms, provided you have permissions in the bridge (happy days self hosters!). We've also added the feature to warn if your messages don't get through in your admin room. Finally, there are a bunch of small bug fixes and one large one that should make the bridge much more resistant to netsplits, so that it should recover in a much safer way should it get hit by a ton of traffic. Please test, and if all goes well the formal release will be out next week!

matrix-appservice-slack hits 1.7.0-rc1

Half-Shot announced:

Happy friday bridge users! Today we're releasing 1.7.0-rc1 of the Slack bridge which contains some more critical encryption fixes for our experimental encrypted rooms support.

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

red_sky☄️ offered:

Nheko now has an optional privacy screen! The timeline will optionally blur when the nheko window loses focus. The timeout for when the blur effect should be applied is configurable in a number of seconds between 0 and 3600 (1 hour).

Nico ( added:

Cheers, some update probably mentioned it already, but FOSDEM is near. Make sure to check out the Matrix stand! RedSky and I (Nico) will probably be there at some random times as well as other cool people from the Matrix-verse! We even made a small promo video about Nheko!

In other news, lorendb extended the drop zone for media to the full timeline, the privacy screen got merged, some more emojis should now display properly, you can now change your avatar and displayname globally or per room and clicking a matrix link in your browser should now actually open the link in Nheko (we were missing the %u in the .desktop file).

That's all, see you at FOSDEM!


fabian offered:

I have been learning about matrix the last few months. The result of that is frost a very basic GUI matrix client written in Go using Gio and a CS library. Highlights of the project so far are:

  • Works on Linux, Windows, macOS and Android (although I only test on Linux and often break the other platforms)

  • Should work on WASM and iOS with not too much effort

  • Very, very limited E2EE support. (If the session is manually verified by other clients, events can be encrypted and decrypted.

  • Library that handles storage, encryption and some other things with a opinionated but simple to use (I hope) interface.

I started this project to understand matrix and improve my Go skills (which are not that great) and if somebody wants to play around with it and give me some feedback on it, I would very much appreciate it. Meet me in

We now have nightly builds for Android, Windows, macOS, AppImages and Flatpak. There is still work to be done to improve the quality of the builds and fixing some platform incompatibility bugs. Nicolas has also been working on optimizing the performance and the RAM usage, fixing a few bottlenecks. Tobias finally landed his big revamp of the login flow and we now support login using single sign-on. Myself (Carl) worked on E2EE support in NeoChat and Quotient.

Since there was talk about it, I went through and updated / cleaned up the MatrixFS code a bit; Got it working with tail -f (and probably other applications that poll based on mtime/size changes), added a GC that drops unaccessed data from memory after a while, and reduced the communication overhead slightly

One week 'til FOSDEM!

In addition to several talks specifically about Matrix, Synapse's own Brendan Abolivier will be speaking in the Community devroom on Mental health and free software: What I wish I’d been told before I got into free software, and more. Check it out!

We're also excited to announce Synapse 1.26.0's release! As mentioned last week, the two biggest new features are a faster algorithm for state resolution and initial support for enabling multiple OpenID Connect providers. Additionally, we've sped up redaction in large rooms and made it possible to run more APIs on workers. See the full changelog for details.

We expect to publish a release candidate for 1.27.0 early next week, but we're trying to be conservative about large changes ahead of FOSDEM, so knocking — which is coming! — will have to wait until 1.28.0... 🚪

matrix-appservice-bridge arrives at 2.5.0-rc1

Half-Shot announced:

Hey folks! It's been a while since we've had an update but things are always manic at bridge HQ. This release is a bit of a whopper containing quite a few bugfixes (including improvements to the experimental encrypted bridge support). We've also updated to Typescript 4.1 which is a bit stricter on those promise return types. Finally, you can now create intents on the bridge and use it's components without starting the HTTP listener which has been a longstanding issue for as long as I've been maintaining.

So go out there and test this release, all going well we should 🚢 early next week!

If only you knew what else this guy was working on. More to be shared soon-ish. I hope!

I reinstalled Fluffychat this week as I attempted to support some less-technically-minded friends, and was VERY impressed. If you've tried FluffyChat in the past but missed recent versions I suggest you have another go.


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

Nico ( said:

On Wednesday we released version 0.8.1 of Nheko! It's mostly a bugfix release of 0.8.0, but it does bring some new features here and there:

[0.8.1] -- 2021-01-27


  • /plain and /md commands to override the current markdown setting. (contributed by lorendb)

  • Allow persistent hiding of rooms with a specific tag (or from a community) via a context menu.

  • Allow open media messages in an external program immediately. (contributed by rnhmjoj)


  • Use async dbus connection for notifications. (contributed by lorendb)

  • Update Hungarian translations. (contributed by maxigaz)

  • Update Finnish translations. (contributed by Priit)

  • Update Malayalam translations. (contributed by vachan-maker)

  • Update Dutch translations. (contributed by Glael)

  • Store splitter size across restarts.

  • Add a border around the completer. (contributed by lorendb)

  • Request keys for messages with unknown message indices (once per restart, when they are shown).

  • Move the database location to XDG_DATA_DIR. (contributed by rnhmjoj)

  • Reload the timeline after key backup import.

  • Autoclose completer on space, when there are no matches.

  • Make completer only react, when the mouse cursor is moved.


  • Fix unhandled exception, when a device has no keys.

  • Fix some cmake warnings regarding GNUInstallDirs.

  • Fix tags being broken. If you have no tags showing up, you may want to logout and login again.

  • Fix versionOk being called on the wrong thread. (contributed by Jedi18)

  • Fix font tags showing up in media message filenames.

  • Fix user profile in dark themes showing the wrong colors. (contributed by lorendb)

  • Fix emoji category switching on old Qt versions. (contributed by lorendb)

  • Fix old messages being replayed after a limited timeline.

  • Fix empty secrets being returned from the wallet breaking verification.

  • Make matrix link chat invites create a direct chat.

  • Fix focus handling on room change or reply button clicks.

  • Fix username completion deleting the character before it.

Flathub and other repo updates may take a bit, but in the mean time you can try building it yourself or one of our provided stable downloads. Thank you for all the feedback so far and I'm glad a lot of people seem to be enjoying it so far! All the feedback, bugfixes and issues you provided certainly will help improving Nheko for everyone!

Then, later...

Apart from the current releases, we have a few things cooking right now:


Yes, I have tried to avoid them for long, but I am finally working on it. It's a bit different to how Element and others do it, but it also generates a fallback to be compatible with the current MSCs where possible. I've grown a bit tired of having to explain myself everytime, why I did not want to support edits (yet), so I'm experimenting with a few solutions now. Expect a blog post summarizing those experiments in the future and maybe an MSC.


Jedi18 and LorenDB are both busy polishing up the rough corners in Nheko, like finally being able to set your username and avatar in the UI as well as being able to copy text via right click, jdenticons and other fancy stuff. We also had a few contributions in the last release, which should improve the UX a lot.


Furthermore we will be participating in GSoC (if gets accepted) and will probably mentor a student, that implements a few of the smaller features, which users may be missing after using Element for long.

I think that is all I wanted to share. I hope you enjoy the release and if you have any issues or feature requests, tell us in or open an issue on Github!


kitsune announced:

Since the project is already fairly rich in features, I decided that it's timely (some would say - way overdue) to bump up the version a bit. In that light, the next Quaternion beta is numbered 0.0.95 beta 3 (no four-number version any more) and it's out now! Release notes list notable changes since ( beta 2, with two most significant being ability to enter messages in Markdown and the overhauled timeline that allows you to easily discern between already read and yet unread messages and also quickly scroll to the read marker.



Neil reported on behalf of the teams:


  • Social Login

    • Final polishing and bug hunting across all platforms. We are targetting 5 options to begin with (Gitlab, Github, Facebook, Google and Apple) and will hopefully be ready to start setting these up on homeservers next week.
  • Spaces

    • Lots of polishing on Element web, you can get all the latest in the matrix live demo session next week!


  • Added some debugging to web to help debug call connectivity failures

  • Fixed a compatibility regression in web with voip v0 clients (ie. element android / ios) - d’oh!

  • Android: work on getting call audio routing correct on various different devices

  • Design coming up to speed to support on implementation and ongoing UI improvements

  • iOS on holiday


  • Off cycle 1.7.18 release for VoIP compat bug

  • Various tweaks to prepare for FOSDEM

  • Element Web 1.7.19-rc.1 is now available at, including:

    • Allowed guest users to see widgets

    • Standardised security terminology to reduce confusion

    • Added ability to pin widgets for everyone in the room


  • We made several iterations since the last App Store release (1.1.3) but Element-iOS 1.1.6 is now in the store.

  • We made some improvements to use less RAM in the background sync module that manages push notifications.

  • We continued to improve performance in E2EE to speed up message sending using pre-sharing keys and re-sharing keys methods. Element-iOS now automatically rejects share requests from not verified devices. It does not send anymore such requests if it is not verified.


  • We are working on improving the initial /sync management. The first objective is to reduce RAM usage. Then, we will improve the time to display the room list.

Just a small dev update on things that currently happen over at the Serverlist project "Keymaker" and its companion bot.

Follow it in detail at or

  • The registration bot finally is starting to get its admin backend -> The registration probably happens in a few weeks from now

  • Keymaker has now a admin login page (using matrix as auth provider) to allow a web UI for admins to manage servers (WIP)

  • The bot successfully writes servers upon registration to the database. This is the main task of the bot besides the capability to administrate the page using the page

  • The bot now is able to be used by admins in an admin room which also gets notifications if a user registered a new server.

Google Summer of Code has come around again! Last year was really successful for Matrix: six projects, with members of the community coming forward to mentor students for their project. This year there is a slight tweak to the formula: the projects will now be 175 hours, rather than the traditional 350, over the summer.

Since we need to submit an application to Google within the next few weeks, I have a request: if you admin a Matrix-related Open Source project and would like to have a student work with you over the summer, get involved!

How to do this:

  • Read Google's own documentation on the setup. This is fairly thorough, and should get you most of the way there.

  • Think about a task, that you consider a student should be able to contribute to your project over a 10-week/175-hour period. Try to come up with 2-3 of these.

    • It should be a well-defined feature that genuinely contributes to the progress of your project, but maybe doesn't block other work on the critical path.
    • This is a very important step, and one that may need some time and discussion.
  • DM me ( and we'll talk about next steps.

Dept of Spec 📜

kitsune (aka "fox-avatar guy") reported:

Matrix URI scheme proposal has FCP proposed now - if any of you, the readers of this, have anything to say about it that wasn't said in the past 2 years, speak soon or forever hold your peace. (Ok, you're allowed to write a separate MSC if you come late with revelations.)

This has been an labour of love for kitsune, kudos on his perseverance!

Here's your weekly spec update! The heart of Matrix is the specification - and this is modified by Matrix Spec Change (MSC) proposals. Learn more about how the process works at

MSC Status

Merged MSCs:

MSCs in Final Comment Period:

  • No MSCs are in FCP.

New MSCs:

Spec Core Team

We've decided to ditch the focus as it was clear that it wasn't a great indicator of progress. Once one team member has reviewed all of the focus items, they will move on to other MSCs. None of that work is reflected in the focus, and items in there often stick around while waiting on a small number of people to complete work on.

As such, we'd instead like to direct people to the Spec Core Team Backlog board, which is a better representation of the current state of things. And of course the weekly list of MSCs state changes above.


Dept of Servers 🏢

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander told us:

At the beginning of this week we released Dendrite 0.3.6, which included a number of refactors in the sync API and a selection of fixes. It is also the first version to be released with multi-arch Docker images with ARMv7/ARM64 targets.

Since then, the following changes have been merged:

  • Sync filtering support for event types, senders as well as better-supported limits

  • Federation support for MSC2946 (Spaces Summary)

  • Fixed a bug where large well-known files could consume a lot of memory

  • Support for in-process DNS caching for federation traffic (although it is disabled by default)

  • Some preparatory work for tracking the most recent membership states in the sync API for future history visibility work

If you are running a Dendrite server, it is highly recommended that you upgrade to the latest version!

Spec compliance is at:

  • Client-server APIs: 60%, up from 58% last week

  • Server-server APIs: 83%, same as last week

As always, feel free to join us in for general Dendrite chat or for development discussion.


Synapse is a popular homeserver written in Python.

callahad reported:



🎉 Synapse 1.26.0rc1 is here!

☠️ But don't install it yet; wait for rc2.

A few issues were reported with rc1 (#9187, #9193, #9208), and we'll issue an rc2 early next week once we're confident they've been resolved.

Otherwise, once 1.26.0 is released you can look forward to a new algorithm for calculating auth chain difference in v2 State Resolution which should significantly speed up some of the most expensive state resolution calculations (#8622).

We've also dramatically improved the performance of redactions in large rooms, helping Synapse's moderation tools scale to communities of any size (#9022). And speaking of scaling, Synapse 1.26 makes it possible to offload many different APIs to worker processes, including read receipts and account data persistence.

Lastly, Synapse 1.26 will include support for multiple Single Sign-On Identity providers, though we expect further fit-and-finish for that feature to land in 1.27.

You can preview the changelog and upgrade notes now, but remember: wait for rc2! 😉

Tulir said:

The switch to acting as a mobile app I mentioned last week has been merged and it's starting to be clear that it works better. So far logging in has worked fine for everyone at least after enabling 2FA.

Changes this week mostly included tons of bugfixes (thanks to everyone who already updated and found the bugs) and re-adding some old features like read receipt bridging. The SQLite migration script now exists too. Upgrade instructions can be found at

Dept of Clients 📱


Nheko is a desktop client using Qt, Boost.Asio and C++17. It supports E2EE and intends to be full featured and nice to look at

Nico ( told us:

Cheers everyone! On Wednesday we released version 0.8.0 of Nheko! The changelog is far too long, because so many people contributed (and it has been a while since the last release), so I'll just put some highlights here!


  • Voice and Video Calls (contributed by trilene)

    • Call your friends right from within Nheko.

    • Use your camera if you want them to see your face!

    • This requires a somewhat new gstreamer, so our builds don't support it on all platforms yet.

  • Cross-Signing and Device/User Verification (contributed by Chethan)

    • Verify who you are talking to!

    • Ensure no malicious people eavesdrop on you!

    • Enable your connected devices to access key backup and your friends to see, which of your devices you trust!

    • Show devices in a users profile.

  • Separate profiles (contributed by lorendb)

    • Run multiple Nheko instances with separate profiles side by side.
    • Use multiple accounts at the same time in separate windows.


  • Before a call select which audio device to use. (contributed by trilene)

  • Auto request unknown keys from your own devices.

  • Add a command to clear the timeline and reload it. (/clear-timeline).

  • Add a command to rotate the outbound megolm session. (/rotate-megolm-session).

  • React to messages instead of replying with arbitrary strings using /react.

  • Inline emoji and user completers. (contributed by Lurkki)

  • Show filename on hover over an image. (contributed by kamathmanu)

  • Mobile mode, that disables text selection and changes some dialogs.

  • Allow sending text after a /shrug command. (contributed by MayeulC)

  • Allow selecting a ringtone. (contributed by trilene)

  • View avatars fullscreen. (contributed by kamathmanu)

  • Request or download cross signing secrets in the settings.

  • Support 'matrix:' URIs. This works in app on all platforms and on Linux Nheko may be opened by clicking a 'matrix:' link.

  • Support inline replies on notifications on Linux.

Packaging is currently in progress, but it will probably take a bit. In the mean time you can download the release from here:

Please tell us, what you think and report bugs as you find them! And thanks again to all the contributors! It was a great pleasure to work with you and you really made an impact!

Over and out, the Nheko team!

Adrien added:
Nheko 0.8.0 was in Debian before TWIM.

❤️ for the packagers!

fluffychat 0.25.0 is out with a lot of bug fixes, improvements, minor design tweaks and a new 3 column layout. iOS will skip this release until we can bring it to the AppStore next week or so


Element for Nextcloud

Gary Kim said:

Element for Nextcloud v0.6.19 has now been released. The new update contains fixes for Single sign-on users, the ability for admins to easily show or hide the labs settings, and an update to Element Web v1.7.17.

P.S. This will be the last version to support Nextcloud 17 and 18 if you're still on those versions.

Element Web instance on IPFS

TR_SLimey announced:

I've set up an Element Web instance on IPFS, which means that now, not even Matrix client downloads can be blocked - censorship resistance at its finest :P

It can be found at:

Updates supplied by the Teams


  • Various widget related improvements
  • Changed guest access to uniformly only allow read access for now
  • Improved CI runtime when testing PRs

caridina, Crystal library

erdnaxeli reported:

Today a present you a Matrix client library I've been working for the last few months: caridina.

It is a Crystal library. Currently for reading it implements the sync API and supports the events to do text messaging (all state events + For writing it provides methods to send messages, edit them, and send receipts and typing notifications.

While I would not recommend this library to write a full featured client, it is enough to write a simple text bot. I currently use it for some of my own projects. The README provides some examples of how to use the library.

Feel free to try it, report bugs, ask for missing features if you need them or even contribute!

libkazv (and the Kazv Project)

tusooa reported:

libkazv is a sans-io C++ (gnu++17) client library

built upon lager. Along with it there is kazv, a kirigami/qml client, and a

forward bot between matrix and tencent qq. Talk to us on

opsdroid is an easy to use chat-ops framework with excellent Matrix support.

0.20 Release

This week opsdroid released version 0.20. This is a massive release that's been a long time coming because of a complete rewrite of the internals of the matrix connector to use matrix-nio---thanks to @awesome-michael for the initial work on this.

Having ported the connector to nio, our GSOC student @Tyagdit got to work polishing the nio port and reimplementing the matrix database module in the core opsdroid library. Opsdroid has a concept of memory which is a key-value store which can be backed my many different kinds of databases. The matrix database stores the opsdroid memory in room state, meaning your bot's database and messages are all stored in the same place.

Finally, the other big feature added to the matrix support in this release is End to End Encryption support. Thanks to using matrix-nio as our matrix library it was possible to implement support for encrypted matrix rooms. This also includes support in the matrix database for encrypted memory which works by referencing event ids in room state (see here for more info). As this is the first release to support E2EE I would still consider it "beta"; please open issues if you have any trouble using it.


  • End to End Encryption support in the Matrix connector.

  • Matrix database now included in core, with e2ee support.

  • Use of Python's install "extras" to allow for installations with fewer packages.

  • Improved documentation of the matrix connector and database (at least a little).

  • Support for Python 3.9 (and dropped support for 3.6).

Checkout the full release notes for all the gory details.

If you have any questions or want to get involved come say hi in, raise an issue on GitHub and checkout the docs.

trixnity (kotlin) progress

Benedict said:

A little sneak peek from trixnity, a crossplatform Matrix SDK. Currently I have some issues with ktor, which breaks my serialization.



kitsune reported:

libQuotient has initiated transition from LGPL 2.1 to LGPL 3 as its distribution license. This is partially driven by the fact that newer Qt is (mostly) distributed under LGPL 3 so the "combined work" (legalese for libQuotient including and linked with specific Qt pieces) would be covered by LGPL 3 anyway. Boring, right?

kitsune added:

Those looking at my contributions to Quotient might have noticed the change of the primary commiter's name. Don't fret, this is still me, I just shed the pseudonym (and those who've seen the interview knew my real name already).

Watch "the interview" here, where we discuss (then) progress on MSC2312 (mentioned earlier), and plenty more.

Matrix Corporal

matrix-corporal manages your Matrix server according to a configuration policy

Slavi reported:

Version 2.0 of matrix-corporal has been released.

It's a huge release bringing many improvements (read all of it in the release notes).

Here's a short summary:

  • an Event Hooks system has been introduced, so matrix-corporal can now also act like a "generic firewall" (similar to what mxgwd was doing)

  • device-free login is now used when impersonating users (thanks to a new API introduced by Synapse v1.24.0) - this is both faster and more resilient.

  • support for Interactive Authentication (and thus, End-to-End-Encryption) has been added. Users can now set up E2EE keys, manage devices, etc. (actions that require Interactive Authentication and were previously broken). Requires cooperation between matrix-corporal and the REST auth password provider module.

  • End-to-End-Encryption control. matrix-corporal can enforce whether rooms that users create are encrypted or unencrypted. You can force-disable or force-enable encryption for locally-created rooms.

  • fixes user-creation regression that happened with Synapse v1.24.0. matrix-corporal v1.12.0 is also out, with a backport of this fix (for users who don't want to jump to 2.0 yet).

Matrix Notepad

KB1RD reported:

  • It's not dead! yet

  • There's been some code refactoring on the algorithm. Mainly, the search tree used has been split into a different package

  • I'm working on porting the Notepad to the new widget API. Ongoing work is on the nextgen branch and is tracked by this project. The widget is currently blocked on some stuff in the widget API, so I probably won't be releasing soon. The code in there needs a ton refactoring, too.

  • This means that the old notepad client will disappear on the next release and you'll need to add a widget for the Notepad for any documents that you want to edit. Currently, this means you would have to use Element, but I heard Ditto just might be doing some widget work

  • The widget API is planned to do everything and more that my "mxapps" project was supposed to do, so that project will be deprecated in favor of using the widget API

  • There's also a little demo/teaser video showing the old notepad talking to the new one. You can see the rate limiting issues that the Notepad hits there, which is on my todo list.

Superb documentation from TU Dresden, as they roll out their deployment

Marvin Dropp said:

We set up a bilingual (de, en) documentation for all of our university members, to help them get in touch with our matrix instance easily. This documentation is rich on screenshots, simple explanations and will be improved continuously.

Also we mirroring the documentation to GitHub to provide access of our sources to everyone.


We would appreciate to add further institutions of higher education with own matrix instances to our list.

Viva la federation!

Christian Bruchatz shared some addional context about their deployment growth:
