Spec Core Team

In terms of Spec Core Team MSC focus for this week, we're switching from QR Code verification to key verification additions. Otherwise things remain the same: MSC2844 (global versioning), MSC2366 (ready and done in key verification) and MSC2790 (modal widgets).


Dept of Servers 🏢


callahad offered:

On behalf of the Americans on the Synapse team: Happy Thanksgiving! This past week saw us land some improvements to the OpenID Connect SSO provider, bringing it closer to parity with the SAML provider. In particular, #8801 made it possible to gracefully handle username collisions when creating a new account over SSO.

We've also merged a pull request (#8785) from @dklimpel which removes deprecated paths for the Synapse Admin APIs. As of the next Synapse release, all Admin APIs will be accessibly only under the /_synapse/admin/v1 path prefix.

Otherwise, much of our time has been spent on getting pull requests like #6739, implementing MSC2403: Add "knock" feature, ready to merge. It's coming to a Synapse release soon!

Speaking of releases, we're looking forward to cutting a first release candidate of 1.24.0 early next week; keep your eyes peeled for that!

I'd be remiss in not mentioning that we started the week by disclosing CVE-2020-26890, which is a denial of service affecting Synapse versions prior to 1.20.0. If you've not upgraded, please do.

Dept of Bridges 🌉


Eric Eastwood offered:

Lots of features added this week including Gitter threaded conversations and Matrix reply bridging, image/file uploads, transforming mentions so notifications flow, and better looking flairs!

Not everything is available on production yet but you can try out the bridge for yourself at

We'll be working through some of the bridge oddities and hoping to open up the bridge to all public rooms on Gitter soon. You can track our full progress from the GitLab epic for the native Gitter-Matrix bridge.


MX-Puppet-VK (Na Zdorovie!)

Alexey offered:

The MX-Puppet-VK bridge for VK (Vkontakte) social network via this commit have added initial support for User tokens. This means that we now can use it for puppeting the real user account, to automatically bridge all "VK Messenger" private dialogs and groups into Matrix. Previously bridge worked only with VK community tokens as bot, to bridge only conversation with specific communities.

To get the VK User token without registering new app (and waiting approve from admins), users can reuse the "Kate Mobile" app token (or other app, that have access to Messages API) and receive it via service.

Support room:


Benedict offered:

The matrix-sms-bridge can finally be used with an Android smartphone as SMS-Gateway instead of gammu and a modem. developed the app android-sms-gateway-server, that the bridge uses to send and receive sms messages. The new bridge version is used in combination with the app in production (medical care centre) for a week now. We have a throughput of 50-100 SMS message a day. The update is also integrated in matrix-docker-ansible-deploy.

Dept of Clients 📱


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 ( offered:

The new completer is now on master. Please try it out and report any issues you may find. It now actually inserts a user link, keeps a per room message history and should look quite a bit nicer and be faster, when completing emojis or user names.

There were also quite a few cleanups, most of them done by Kirillpt! Some spacing here and there, saturation changes, the login page should now be less confusing, when you don't enter a valid mxid and toggles should now not get stuck in confusing intermediate states. There is also a russian translation now and some VOIP fixes. Pretty busy week, but I like it!



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

krille reported:

FluffyChat 0.23.0 is out now with password recovery options and a lot of minor fixes and UX improvements. Now also available on Flathub!! 🙂 Learn more at:



Nad offered:

In development

Improving usability

On mobile, we’re busy adding better suggestions to empty/starting views of screens, improving searching for contacts, improving adding other users by QR code scanning, and improving deep link integrations on Android. Expect releases for iOS & Android soon!


Spaces UI designs & user research testing are underway, with initial development for the Element Web client kicked off too. We've been doing research & testing in private to avoid advance bias from the people we're testing with, but hope to share things publicly soon.

Social login

Social login is in review for Element Web, with synapse & mobile support hot on the tails for next week prior to releasing.


We’ve been focusing on implementing UI for call holding, and general UI polish across the VoIP experience, to be released soon!


Element Web

Element Web 1.7.14 was released this week, which includes:

  • Several tweaks and improvements to the room list filter

  • Improved registration based on user feedback

  • Improved invite / create DM flow.

  • Future releases will no longer publish element-web to NPM, and the package is marked as deprecated

  • Renamed build artifacts from riot-.tar.gz to element-.tar.gz

  • Experimental LaTeX maths rendering support is available via a labs flag on develop. Thanks to akissinger, thosgood, uhoreg, and others who have worked on various pieces of this puzzle!

Element iOS

Element iOS 1.1.1 has been released:

  • It contains contains several major bug fixes, including end-to-end encryption bug fixes.

  • Full history available on GitHub viewing the 1.1.1 & 1.1.0 tags.

Element Android

The Element Android 1.0.11 release is pending:

  • We're working through final bug fixes.

  • Separately, we’re also working on adding missing features to the client like; managing room aliases, room history visibility, join rules, etc.

  • In the SDK, the migration of the services API from MatrixCallback to coroutines is going well, tracked here.


CraftedCart offered:

In addition to boring stuff like being able to persist events (hopefully) right, so we don't have to initial-sync every launch, I've been making a start towards multi-account support!

You can sign in as multiple users and switch between the "active" user you want to send messages as - iit's a bit flaky for now, esp. when scrolling up to read past messages, but hey it's a start I guess

Asked if they were using an SDK:

Preeetty much doing it from scratch, though I am loosely basing the matrix-api side of it on Ruma

Source is at

Dept of SDKs and Frameworks 🧰


Ruma is a set of Rust library crates around Matrix.

jplatte announced:

We gained a new contributor, kiwidu38, who added the server-default push rules, paving the way to Conduit supporting push notifications.

I improved compatibility with some commonly-broken DAG events and added rudimentary support for message edits to help Fractal finish their move onto matrix-rust-sdk.

Dept of Guides 🧭

Matrix introduction series (German)

Samuel offered:

I published the second part of the Matrix introduction series on my blog (in German). It deals with end-to-end encryption, contact verification and cross signing.

I have not read this series so I must trust that Samuel is saying nice things! Anyway it seems like a useful resource for telling kameraden about getting started with Matrix.

Matrix in the News 📰

Niklas Zender offered:

Today there is a German article about Famedly on Gründerszene -> Famedly is developing a solution based on Matrix to enable healthcare providers to communicate securely with each other and to facilitate intersectoral processes such as patient transfers or the integration of IomT devices. We have also almost completed a successful financing round and hope to support the Matrix ecosystem more and more. It would be so cool to use FluffyChat, Element, or a Matrix Messenger of your choice to start a video consultation with the doctor of your choice, or to be integrated into existing clinical communication flows concerning you!

Congratulations to Famedly on the progress they're making! If you're ready to graduate from TLAs (Three-Letter-Abbreviations) to the next stage, you'll be please to learn "IomT", which means "Internet of medical Things".

Dept of Ping 🏓

Here we reveal, rank, and applaud the homeservers with the lowest ping, as measured by pingbot, a maubot that you can host on your own server. Join to experience the fun live, and to find out how to add YOUR server to the game.

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander said:

We started out this week by releasing Dendrite 0.3.0 and then ended the week with a bug-fix Dendrite 0.3.1 release.

I'd like to say thank you especially to our community contributors who have been adding new features and filling gaps!

Changes this week include:

  • Memory optimisation by reference passing, significantly reducing the number of allocations and duplications in memory

  • A concurrency bug has been fixed in the federation API that could cause Dendrite to crash

  • A hook API has been added for experimental MSCs, with an early implementation of MSC2836

  • Forgetting rooms is now supported (thanks to S7evinK)

  • The last seen timestamp and IP address are now updated automatically when calling /sync

  • The last seen timestamp and IP address are now reported in /_matrix/client/r0/devices (thanks to alexkursell)

  • An optional configuration option sync_api.real_ip_header has been added for specifying which HTTP header contains the real client IP address (for if Dendrite is running behind a reverse HTTP proxy)

  • Partial implementation of /_matrix/client/r0/admin/whois (thanks to DavidSpenler)

  • The error when registering a username with invalid characters has been corrected (thanks to bodqhrohro)

  • The -version command line flag has been added (thanks to S7evinK)

  • Backfilling should now work properly on rooms with world-readable history visibility (thanks to MayeulC)

  • Some more client event fields have been marked as omit-when-empty (thanks to S7evinK)

  • The script has been updated to work properly on all POSIX platforms (thanks to felix)

Spec compliance is unchanged, although some Synapse-specific tests have been removed and some new tests have been added:

  • Client-server APIs: 58%, same as 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.


callahad offered:

We released Synapse 1.23.0 on Wednesday! Read all about it on the Matrix Blog. Otherwise, we'd like to highlight a few developments over the past week:

  • We're discussing a policy for ending support for old versions of Python and PostgreSQL. If you have opinions, please let us know on GitHub.

  • Our initial implementation of MSC2403: Add "knock" feature is undergoing review, and will likely land soon.

  • We've been looking at ways to improve the efficiency of state resolution, and Erik has managed to devise some algorithmic improvements that yield an order of magnitude speedup for a handful of pathologic cases. We hope to have a better idea of how this might work for real world workloads soon.

Lastly, we'd like to take this opportunity to remind you to please regularly upgrade your Synapse. Especially if you're not yet on 1.20.0, as we'll be disclosing a denial of service issue which affects older versions on Monday.


Tulir said:

mewmew wanted to use my fork of Synapse, so I made the changes there configurable (instead of hardcoding to my user ID) and even added a readme to list the features. It might also be useful for other people who want custom room IDs and other fun stuff.

The fork is available at

mx-puppet-discord is a (double)puppeting and relay bridge for discord, based on mx-puppet-bridge

sorunome told us:

Support for receiving EDUs from matrix (typing, read indicators and presence) has been added. Protocol implementations can start using the new events, if they want to. Version 0.1.0 has been released along with this. You have to enable the de.sorunome.msc2409.push_ephemeral flag in your registration file


Added support for bridging typing and presence matrix->discord


Eric Eastwood offered:

The native Gitter <-> Matrix bridge is in production! 🚀🚀 We're only testing it out in a single room but feel free to come by and send a message 😀 <->

We also have edits from the Gitter side flowing to Matrix and soon to support edits from Matrix. You can track our full progress from the GitLab epic for the native Gitter <-> Matrix bridge.



Coma Grayce told us:

Hey, our team of colorful ponies proud to introduce you a new Matrix bridge to chats. It's powered by mx-puppet-bridge and so far supports almost all of core features people want to see, like replies, message edits and file attachments.

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 ( announced:

  • Profiles should now open again on older versions of Qt.

  • I've been slowly rewriting the message are to be qml, to make it easier to do fancy styling. As a result emojis in the emoji-completer are now colorful and the avatars in the username completer now match the avatars used in the timeline. It also open up a few other improvements, like finally sending mentions as links instead of plain text.

  • We have now CI running on our self hosted gitlab instance. We will probably switch of the travis CI, once this is more battle tested. Repositories are now also automatically mirrored between gitlab and github.

  • Fixed a bug, where we tried to read the internal world group on your server instead of keeping that to ourself.


Nico ( offered:

I released 0.0.3 a few days ago bundling a few smaller improvements like redactions, copying messages and the ability to click on more links as well as some visual cleanups. Nothing radical, but also nothing breaking (I hope).

Delight (Rich vdH, Michael (t3chguy), Valere, Steve, Nique, Nad)

  • Improving usability

    • Last week

      • Observed user tests of people trying to use Element for the first time for personal and professional use cases
    • This week:

      • Began work on fixing several of the issues observed, like:

        • adding an invite people button to new rooms, so users can more easily add people;
        • changing copy to help people understand what DMs are
  • Spaces

    • Communities are coming back with a bang! Last week we said we renamed them to Spaces, and this week, we’ve started designing what MSC1772 would look like for users on Element, to start user testing next week.
  • Social login

    • To make authentication easier, we’ve started initial implementations of SSO in Element, exploring how homeservers & Matrix clients can support multiple SSO providers. Most of the work so far is captured in MSC2858.

VoIP (Dave, Brendan, Ismail, Francois, Simon, Nad)

  • Web

    • PR up for new look in-call UI, now looking at line 1 / 2 support
  • Mobile

    • Work ongoing to update both platforms to v1 VoIP
  • Design

    • Some tweaks as implementation is ongoing

Web Platform (Ryan)

  • Element Web 1.7.14-rc.1 is now available at <>, including:

    • Several tweaks and improvements to the room list filter

    • Improved registration based on user feedback

    • Improved invite / create DM flow

iOS Platform (Manu, Gil)

  • Last week:

    • The release has been blocked because a bug has been found in the end to end encryption module. It has been fixed but we want to fix damages it created on one time keys before releasing the new app version.

    • The new background sync service mechanism PR has been updated

    • We started to integrate tuist to stop to be annoyed with merge conflicts on the Xcode project file

  • This week:

    • Release!
    • Merge the background sync service mechanism PR and make more people test it

Android Platform (Benoit, Onuray)

  • Last week:

    • We’ve just merged a lot of PRs, to improve room creation form and fix some bugs.
    • SDK side, Dominaezzz is converting some of the Service API methods to coroutines, for a cleaner code. See for instance <> . 9 out of about 45 services have been migrated so far. We have about a 45 services in the SDK (!)
  • This week:

    • Release including a new way to invite friends to Matrix and to Element.


Bruno reported:

Released 0.1.30 with image uploads. There is also a new preference in the settings to scale sent images down.

Ruma is a Rust project to create a comprehensive set of APIs for Matrix. Previously there was a Ruma homeserver project.

jplatte said:

Since our last update four weeks ago,

  • iinuwa created issues for all of the identity service api endpoints (w/ suggested module names!) 🎉

  • I updated lots of enumerated types to allow unspecced values, for future compatibility & robustness

  • Devin R made sure a custom Content-Type in responses overwrites the default rather than creating a duplicate header. #339

  • gnieto fixed a bunch of bugs in ruma-federation-api

  • Alejandro Domínguez added support for deserializing string power levels (requires the unstable-synapse-quirks feature because these events are invalid according to the spec but Synapse used to (?) accept them)

Ruby SDK

Ananace reported:

Just released version 2.2.0 of the Matrix Ruby SDK with the help of the community, with this release support for JRuby is improved - though still not perfect, in the higher-level abstraction direct messaging rooms are now exposed for all users - as well as all that the current user has, and the lower-level abstraction sees the addition of the CS API method to get an event context.

And just to reiterate; if you're using the gem - or have questions/comments about it. please do drop into the discussion room at

Dept of Bots 🤖

You can see demos of both bots in this section by watching Matrix Live \o/

home-assistant-bot v2.0.0 released

Oleg told us:

Opsdroid bot for triggering home-assistant automations.


  • ⚠️ Possible breaking change: change behavior how messages are matched

    • Before: messages were matched only if a message starts with !

    • In this version: the whole message is matched. This means in v2.0.0 this will work Hey, please !turnon light1

      • You can override this by using ^ in the config for. For example: regex: "^!turnon"
    • This allows one bot trigger another. See this TWIM video for details. 😉

  • Add howto for setting up wakeup-light with home-assistant

  • Update Opsdroid to v0.19.0

  • Update opsdroid-homeassistant to 0.1.8

  • Add debug config parameter to display messages in the chat, that the bot is getting but, maybe, is not processing/matching


Famedly Timetracking bot

MTRNord announced:

As seen in the video I am working at famedly on a bot to track our work hours.

Until this happens the video gives you a sneakpeak on the functions of that bot.

Current (implemented) functions

  • Tracking of time using !in and !out commands with forced usage of a description as well as ISO 8601 timestamps.

  • Verification if a time is logical based on the known data

  • Saving the times tracked inside of postgresql

  • Tracking durations using a !record command

  • Responding to only allowed users. (Including ignoring invites if a user is not allowed to use the bot.)

  • Using !delete to remove entries from the database as needed

Planned functions

  • Handling of timezones based on users

  • !stats command which prints you the tracked durations based on a predefined or custom range of time

  • CSV Export based on a defined range

  • !break command. Puting a break in between a record or a in/out combination.

  • Better handling of multiple !in commands

  • Improved responses

  • Reminders to call !out and to take breaks

Fell free to join us at . As soon as the repo gets opened up to public we will announce it in TWIM. Feel free to give suggestions or wishes in our room :)

The IETF have been continuing to experiment with new chat systems, and exists as a three-way bridge to discuss the initiative spanning Matrix, XMPP & Zulip. Really fun to see open chat converging like this :)

Dept of Science 🧪

Analysis of the Matrix Event Graph Replicated Data Type

Florian announced:

Fresh off the arXiv presses comes our

“Analysis of the Matrix Event Graph Replicated Data Type” preprint! This time, it is a deep dive into the data structure properties of the event graph:

What type of consistency guarantees does it provide, how many of the other homeservers you share a room with can be faulty or malicious without violating those guarantees (short answer: all of them!),

and how is it possible that a frayed-out event graph ever laces back to just a few current events, while there is a probability larger than zero for growth to arbitrarily high limits?

To shed light on those questions, we had a great cooperation between my Decentralized Systems and Network Services Research Group and Prof. Dr. Norbert Henze from the Institute of Stochastics.

While we are still in search of the right venue for peer-reviewd publication, we went for a preprint this time to share our results with the scientific and the Matrix community in a timely manner.


In this figure, k is the number of participating servers, U_n is the current width of the event graph.

For example, with a current width of Un = 1000 events and k = 200 servers, we can expect that the width goes below E(U{n+1}) < 600 events in just one step.*

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

In terms of Spec Core Team MSC focus for this week, MSC2744 has entered FCP. As such we're switching it out for MSC2844, which aims to define a global versioning system for all spec documents. Note that MSC2844 does not currently have FCP proposed. Its purpose for being in the focus this time around is for asking the team whether ideas proposed are plausible.

Thus this week's focus is MSC1544 (QR Code verification), MSC2790 (modal widgets) and MSC2844 (global versioning).

We've also started making use of a Github board to track the state of an MSC through the currently somewhat ambiguous process of putting up an MSC that is ready for review to starting FCP. You can find the board here: SCT Backlog.

Some explanation of the columns:

  • Awaiting SCT Input - These are MSCs that are deemed reviewable by the MSC author, and require review by a subsection of the Spec Core Team (usually one or two people) that are most familiar with the scope of Matrix that the MSC is relevant to.

  • Ready for FCP ticks - At least one individual from the Spec Core Team has signed off on the MSC. It is not time for others to give a cursory review - mainly sanity checking from the perspective of the part of Matrix that they work on. Note that fundamental flaws may still be found in this stage, requiring the MSC to be reworked.

  • In FCP - The MSC is in Final Comment Period, where everyone has a last chance to get their ideas in. This happens after most of the Spec Core Team have given their ticks from the previous column.

  • Done - These MSCs no longer need immediate attention by some portion of the Spec Core Team.

These definitions are all flexible as we continue to see what works for the limited resources we have available for review.

Do not be alarmed if a particular MSC is not on this board, we're placing things on here as deemed necessary, and more will certainly be added in time.


New spec platform

wbamberg reported:

Working on the new spec platform: this week we've been simplifying the toolchain that builds and renders the spec, to make spec authoring easier and faster.

Dept of Servers 🏢


callahad offered:

Note: We are aware of a trivially exploitable denial of service vulnerability in versions of Synapse prior to 1.20.0. Complete details will be disclosed on Monday, November 23rd. If you have not upgraded recently, please do so.

Happy RC day! The first release candidate of Synapse 1.23 is now available. For Synapse admins, we've added numerous new APIs thanks to contributions by @dklimpel, and we now support generating structured logs in a standard manner. The structured and drains logging options are now deprecated in Synapse's configuration.

Synapse 1.23.0rc1 also includes several significant bugfixes, especially around regressions in the SQLite-to-PostgreSQL database porting script, as well a fix to an issue that would prevent Synapse from recovering after losing its connection to the database. Synapse will also now reject modifications to access control lists which would otherwise result in a server blocking itself from a room. This is a particularly interesting case of unintended consequences in protocol design, and we hope to write more about it soon.

Next week should see the full release of 1.23, followed by a first implementation of MSC2403: Add "knock" feature landing in the development branch for 1.24. Look for more information in next week's edition of TWiM!

kegan said:

Neil is still working on P2P routing schemes and I am still working on Cerulean, but that doesn't mean nothing has happened this week! We've been busy reviewing PRs and have landed a big one this week:

  • Read receipts are now implemented (thanks @S7evinK!).

  • Usernames with = can now be created, in accordance with the spec.

Spec compliance has improved as a result:

  • Client-server APIs: 58%, up from 57% last week.

  • Server-server APIs: 83%, up from 81% last week.

Pierre offered:

YunoHost is an operating system aiming for the simplest administration of a server, and therefore democratize self-hosting.

Synapse integration had been updated to 1.21.2 (1.22.1 available in branch testing)

Element Web integration had been updated to 1.7.12 (1.7.13 available in branch testing)

Bruno said:

Hello all. Hydrogen gained emotes (/me) this week, together with file uploads and downloads! Also, encryption keys are setup while typing instead of after sending, so you should see less momentary "the sender hasn't sent the keys yet". Also a good number of bugs were solved. Next up: image uploads!

As expected, /me commands brought a chorus of:

now that you support commands, you must add the single most important command in any decent Matrix client

- tulir

Bruno got the idea pretty quickly:

/rainbow perhaps?


Nad announced:

Hello TWIM! From this week on we're changing how we're reporting updates on the Element clients. Each week, we'll include a section for cross-platform feature work the Element team is working on, and some sections for platform specific work too.

Spaces (previously known as Communities)

Communities are back! They've been renamed to Spaces, and on the Element team we've been busy exploring user experience and critical thinking for MSC1772, to allow users to organise rooms into useful groups.

Social Login

In an effort to reduce friction in authentication, we've been R&Ding how to allow homeservers & Matrix clients to support multiple SSO providers.. Most of the work so far is captured in MSC2858 and we're starting initial implementations in Element web next week.

VoIP: Voice & Video Calls

We've started foundational research, design and engineering to improve both the usability and stability of native matrix VoIP in Element. We've also started to look at how we can improve the continuity of the user experience between native Matrix calls and our current implementation of Jitsi.


We've been focusing on improving post-registration actions all round to make Element provide better prompts for first actions, and empty states for views on all platforms, with a multitude of fixes having landed on Element Web, iOS & Android in the last week. We've also started paid user testing to better understand specific pain points in the first time user experience, which we're looking to improve significantly in the coming weeks.

Web platform

v1.7.13 is now live! Which includes a bunch of fixes & improvements on VoIP.

iOS platform

v1.1.0 is soon to be live on TestFlight for beta testers, and we'll soon be turning our attention to fixing end-to-end encryption regressions.


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 ( reported:

  • You can now see yourself too during a video call.

  • You can change the ringtone, as the default can be a bit annoying.

  • Avatars should now not look as pixelated in some weird edge cases.

  • You can now add text after a /shrug command.

That's all, thank you trilene and MayeulC for the contributions!

matrix_app_service.ex (Elixir SDK)

pierre told us:

We've (finally) released a first version of matrix_app_service.ex, an Elixir library for the application service API (hex, GitLab)

uhoreg (known Elixir fan, asked):

that's cool. Do you have any projects that are using it?


I don't want to "sell" it before there's some kind of poc, but with a few friends we're trying to build a bridge for ActivityPub. we're using the library of the same name by the people behind CommonsPub, of which a lot of code comes from Pleroma, so the application service appears as an ActivityPub server. it's still the beginning, and I'm just starting to think about which information a bridge needs to keep (I guess sometime I'll ask Half-Shot a big list of questions 😁)

Today might be our highest-ever Pierre-ratio in TWIM!


Benedict announced:

A new release integrates an embedded h2 database into matrix-spring-boot-bot, which makes it a lot easier to write bots with persistency. You only need a few lines of code to write simple bots (e. g. a ping bot). I also changed a lot under the hood (e. g. using type-safe Matrix-Id-classes instead of Strings).


The matrix-sms-bridge now uses the h2 database from matrix-spring-boot-bot instead of neo4j, which makes it a lot more stable and fixes some bugs. We are using it in production with hundreds of target telephone numbers without problems. I also added an optional feature to use room aliases (e. g. #sms_4901234567:homeserver) to prevent multiple rooms with one target telephone number (which is still possible).

In a few weeks you can use this bridge with an old Android-Smartphone, which acts as an sms gateway with rest api.

Dept of Built on Matrix 🏗️, new social network getting Matrix integration

ahq said:

Hello Matrix friends. I've been asked to share this here. I'm currently building a platform for building communities. I'm focused on deeper matrix integration with communities, private messaging built on top of matrix, and custom domain support. Feel free to check out The matrix community is at, but I haven't had the time to post much.

We have communities ( ->

We have galleries ( -> We have publications ( ->

We have user pages ( ->

The UI is a little confusing now because we have longform articles ( and short social media posts (

I pretty much want all resources to have custom domain support, and matrix rooms for all communities, and nested communities. In the near future, I hope to have matrix servers for custom domains too. And of course, the source will also be open if folks want to host.

Right now, users on gurlic get a matrix account, and communities/galleries/publications get a room too, but i'm hoping to take some time to look at much deeper integration. Dendrite and hydrogen are great to build on top off...

Happy November from the Synapse team! As mentioned last week, we pushed a small v1.22.1 release last Friday which fixed two regressions:

  • Fix a bug where an appservice may not be forwarded events for a room it was recently invited to. Broke in v1.22.0. (#8676)

  • Fix Object of type frozendict is not JSON serializable exceptions when using third-party event rules. Broke in v1.22.0. (#8678)

If you haven't upgraded your Synapse in a while, please do.

Matrix SDK for Elixir

cognitive_tea reported:

Hi all! I think this is the right place to share this 🤞. I've been working on a Matrix SDK for Elixir over the last few months as a side project, it's very early days and it's currently just a bare-bones wrapper for the Client-Server API. I've also written the Elixir/Erlang bindings for Olm (currently missing group sessions) which should be added to the SDK soon. The repo can be found here: and the Elixir bindings for Olm are linked in the readme.

It is the right place! Thanks cognitive_tea :D

Asked if there were big plans for use of the project

Not as yet, though a few people have reached out to me already and are building on top of it. I started it as a way to get going with Matrix dev and as a fun side project. That being said, I think providing the tools to Matrix-enable Elixir apps might lead to some interesting things. If anyone has any precise ideas on how they would want to integrate their Elixir apps with Matrix, I'd be super happy to have a chat 👍️ Less precise ideas are also welcome, of course 🙂

Dept of Bots 🤖

matrix-media-repo is a highly customizable multi-domain media repository for Matrix

TravisR announced:

v1.2.1 of matrix-media-repo, a third-party media repo for large homeservers, is out now. It's primarily a maintenance update though also has support for audio files if for some reason you need that.



callahad said:

Synapse 1.22.0 is out! We announced its first release candidate last week, and after a small rc2 the final release was published last Tuesday. We anticipate a small 1.22.1 release later today with fixes for messages not always being sent to app services (#8673) and serialization errors with third-party event rules (#8678).

We continue to see improved client join Apdex scores for, indicating that our work in 1.22.0 to split background tasks into separate workers and allow for sharded event persisters successfully improved the user-visible performance of large homeservers.

In other news, we pushed a temporary hotfix to the homeserver earlier this week, instructing it to drop all cross-user m.key_share_request messages. This was necessary to mitigate a bug in a third-party library which caused some clients to flood the server with requests. We'll re-enable these messages once we resolve issue #8677. In the meantime, we strongly encourage FluffyChat users to upgrade to version 0.21.1.

We're hard at work on the next release of Synapse, and the development branch already includes many bugfixes, several new admin APIs, and support for structured logging—stay tuned!


Dendrite is a next-generation homeserver written in Go

kegan said:

There is no release this week, be sure to have v0.2.1 installed for a more stable experience! A few documentation changes have been made this week:

  • Docker sample configs are now correct.

  • The MaxMessageBytes for Kafka messages is now configurable - thanks @S7evinK!

  • A reverse-proxy sample now exists for Hiawatha - thanks @ErgoPoe!

Spec compliance remains unchanged:

  • Client-server APIs: 57%

  • Server-server APIs: 81%

Things have been quiet this week because Neil has been working on new P2P routing schemes and I have been working

on a Threading proposal which will be tried out in Dendrite in the coming days.

Hey folks, today I bring you a gift wrapped rainbow coated present, which could only mean Bifrost 0.2.0 is out!.

We've been making major progress trying to align bifrost with the many XMPP clients out there like Gajim and Swift, by improving it's compatibility with the various XEPs. I've also noticed a few users have started using it to bridge their Matrix and XMPP communities together which is super cool :)

The merge request for the native Gitter bridge has just got underway and we're making progress towards sharing all Gitter messages in public rooms across to Matrix.

We'll continue to iterate on the Gitter virtualUser support as we go along.


Tulir said:

v0.9.0-rc1 was released last weekend. Changes since v0.8.x include:

  • Prometheus metric names are now prefixed with bridge_

  • Support for Telegram QR code login

  • Support for double puppeting for users on other servers

  • Options for automatic backfilling of missed messages and old messages when creating portals

  • Switched end-to-bridge encryption to use mautrix-python instead of the previous hacky matrix-nio solution

This week I fixed some bugs, so I'll probably make a rc2 in the near future.

Element Android

benoit offered:

We are making progress on the performance side. Now sending an event is much faster than before. We also are optimizing the crypto code. All those improvements will be available in the next release (v1.0.10), maybe next week?

Besides that, we are implementing the remaining features, we are trying to have the same level of functionality (= parity) than Element Web. We know that we have a great number of bugs to fix on the existing feature, we are also trying to fight them.

As a reminder, the new Android Matrix SDK is available at and a nice sample application has been developed and is available at

You had me at "progress on the performance side"! I am looking forward to the new Element Android :D

Element Web

Neil reported:

This week we shipped Element 1.7.12 which contains some high priority fixes, specifically:

  • Fixes secret storage / cross-signing reset to avoid asking for the previous key you no longer have
  • Fixes widget pinning and Jitsi calls when custom themes are used

Aside from that we continue to work on the voice and video calling experience as well as improving the initial onboarding experience of the app.


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 ( offered:

This was an exciting week again. Trilene did the usual and just opened a PR, that implements the video part of call support. In my testing so far this seems to work amazingly well (ignore, that my webcam is crappy in the video, I only have so many devices...)! It's hard to overstate my satisfaction, if I am allowed to quote songs without getting a DMCA! If you want to try it out, you will need the qmlgl plugin at runtime (I had to patch some ebuilds on Gentoo to do so) and build Nheko from source. Support in our AppImage and Flatpak and for our Windows and MacOS builds will come at a later date. A big shoutout to trilene, who just works on VOIP in Nheko, without saying a word, and then drops a ready PR.

Another exciting new feature by lorendb, you can now specify --profile <profilename>, when you start Nheko, to create a separate profile. This allows you to open multiple instances and use multiple accounts at the same time (but it still uses separate instances of Nheko). This is pretty useful, if you have multiple accounts on different homeservers or are testing stuff for example. He also added a shortcut to delete the current content of the message area (Ctrl-U).

We also fixed a long standing bug, that crashed Nheko when pasting an image on mac OS, prevented copying text in some cases and build times should be about halfed again.

That's all I got today. I guess we should do a new release at some point?

I asked about trilene, who is a reliable Nheko contributor, Nico replied:

trilene seems to be a bit camera shy and prefer to work on code than take credit and talk about upcoming features. I'm surprised everytime, when a new PR is opened or trilene asks a weird question, that can only end up in an amazing contribution :3

matrix-bot-sdk 0.5.8 out now

TravisR told us:

matrix-bot-sdk v0.5.8 is out now with experimental support for EDUs being sent to appservices (per MSC2409).

To enable it you'll need Synapse 1.22.0 (released this week) and v0.5.8 of the bot-sdk. Then, add "de.sorunome.msc2409.ephemeral": true to your appservice registration file (at the root level) and turn on the de.sorunome.msc2409.ephemeral flag in your IAppserviceRegistration supplied to the bot-sdk. If all goes according to plan, you'll be able to use appservice.on("ephemeral.event", (ev) => {}) to start processing EDUs.

Enabling encryption for bots on

TravisR offered:

Starting November 28th and 29th of this year, many bots on will be supporting end-to-end encryption. Though not all bots will be supporting it, this is an important milestone towards getting end-to-bridge encryption enabled on as a proof of being able to scale to the higher demand of encrypted rooms.

The eventual goal is to support encryption on all of’s bots and bridges, however we need to take small steps to get there 🙂. Note that in order to function, bots will decrypt all messages they see, but only respond to the ones they care about - this can still be uncomfortable for some rooms though, so feel free to kick them out.

For more detail on which bots are getting support and what all this entails/means, please see the dedicated blog post.

We teased this a little on Matrix Live last week (I think?), but so awesome to see this publicly announced.

Keymaker (Serverlist Project)

MTRNord reported:

Keymaker is a new WIP Project of some people (over at ) that aim to provide a mastodon alike Server List and we would love to get some more input from the Community for this project on whats wanted, whats needed and whats maybe not that good to base on the mastodon counterpart.

This means we are building:

  • A list of Servers where Owners can add their servers

  • We try to do Quality controls (No fully self add. Servers get reviewed.) using a Code of Conduct Ruleset

  • Verified Listings using well-known files on serverside (Also allowing Admins to modify server data themself)

  • Server Details like:

    • Ping and Avalibility Stats (thanks to tulir for providing a API)

    • Public Room Lists fetched from the Server

    • NSFW Ratings (A NSFW tag was too generic for us)

    • A Section to list Rules

    • Admin adresses for easy ways of reaching the Server admins

  • Allowing to select registration state ("Open", "Invite Only", "Closed")

The Code is fully written in Rust and using Postgres as a backend. Have a look at:

Join us at:

In a further post we plan to announce the launch of this Project as a Website. Server owners might get a ping before that to allow for setting up servers for this. This Project is not yet deployed to be used.

This is really cool. I suggested it might start to kickstart people hosting their own small, publicly open servers.

MTRNord replied:

As we also allow non public servers (registration -> closed) it may also be a nice way to find communities that federate and have a look if they have a intresting room to join in the public rooms list. :)

Dept of Servers 🏢


Tulir told us:

I made a simple room alias proxy: It can be used to create room aliases on custom domains without having to host an actual Matrix homeserver there. The proxy basically just responds to federation room alias queries using data from another homeserver (that data is fetched with the C-S API).


callahad reported:

A new release candidate appears! Synapse 1.22.0rc1 was published yesterday and includes support for running background tasks in separate worker processes, as well as fixes to sharded event persisters which were first introduced in 1.21.0.

These changes significantly improved our client join Apdex score for by making join performance both faster and less variable.


Synapse 1.22.0rc1 also includes support for a few experimental MSCs:

  • MSC2732: Supporting olm fallback keys

  • MSC2697: Supporting device dehydration

  • MSC2409: Allowing appservices to receive ephemeral events like read receipts, presence, and typing indicators.

Lastly, the default room version is now version 6, per MSC2788.

In the coming weeks we'll focusing on improving Synapse's resilience in smaller to medium-sized deployments, primarily through improvements to state resolution. Stay tuned!

Thanks Dan!

Today's update comes courtesy of Dan Callahan (, who joined Element on Monday as an engineering manager supporting the Synapse team. Dan previously worked in Developer Relations at Mozilla, and he's excited to help Matrix realize its ambitious vision for private, secure, and standards-based communication for all.

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander offered:

This week we released v0.2.0 on Tuesday, a reasonably big update containing various improvements over the initial beta release, and then followed it up with a bug-fix v0.2.1 release on Thursday.

Thanks to everyone who has been running Dendrite and reporting their findings, and also to contributors who have been submitting pull requests!

Changes this week include:

  • Dendrite no longer builds separate binaries for each polylith component, but instead has one multi-personality binary

  • Our Docker images have been simplified into two images: dendrite-monolith and dendrite-polylith

  • Internal HTTP API calls are now made using H2C (HTTP/2) in polylith mode, which resolves some head-of-line issues with the connection pool

  • Forward extremities have been refactored, which should fix some cases where room state can end up corrupted

  • A couple of bugs when handling state rewrites have been fixed

  • The sync API no longer sends old state events to clients as if they were new

  • SQLite locking bugs around the latest events updater have been resolved

  • Notification levels are now parsed correctly in power level events (thanks to Pestdoktor)

  • Invalid UTF-8 is now correctly rejected when making federation requests (thanks to Pestdoktor)

Spec compliance for v0.2.1:

  • Client-server APIs: 57%, up from 56% last week

  • Server-server APIs: 81%, up from 80% last week

As always, please feel free to join us in for general Dendrite chat, and if you are interested in contributing!


Timo stepped in to tell us:

This was another productive week:

  • Improved thumbnailing algorithm (higher quality, less stored data, correct)
  • Allow unjoined users to read state of world readable rooms (this makes work with conduit)
  • Docs for cross compiling conduit
  • Fixed stuck / double-join over federation
  • Fixed random timeline reload bug
  • Welcome message in admin room
  • More frequent flushing

Some WIP things:

  • Provide Conduit binaries for most platforms to make setting up or updating a Conduit instance even easier
  • More reliable sending over federation
  • Bring all features of our Ruma fork upstream

Thanks to everyone who supports me on Liberapay or Bitcoin!

Homeserver Deployment 📥️

Dendrite docker images

Dendrite is a next-generation homeserver written in Go

TR_SLimey offered:

I built some unofficial Dendrite docker images for Linux/ARM64, for those trying to run Dendrite on a Raspberry Pi, RockPro64 or others. They can be found here: &

balaa reported:

Cool, we run Synapse on Pi0, Pi2 and Pi4 -- works reasonably well on each of them, i'm excited to try Dendrite

Synapse running on a Pi zero..?

Dept of Bridges 🌉


Eric Eastwood announced:

The initial iteration of virtualUsers is in shape to merge(check out the flair 🔥) and will probably deploy in a release next week. We've split the rest of the virtualUser work into follow-up issues we can iterate on. We're working on adding room ban and spam detection support for virtualUsers to stop any bad actors. Then want to start on the actual Application Service bridge (Gitter <-> Matrix).


If you're curious about more of the details, you can track the greater GitLab epic.

🌈🌉 Bifrost* 0.2.0 is (nearly) out

Half-Shot offered:

I couldn't really wait to talk about before we actually hit 0.2.0 so here is a sneak peek at what's happening. We've spent a ton of time working on ironing out the bugs and making the bridge more XMPP complaint. The major headlines are:

  • Support Matrix -> XMPP edits

  • Set XMPP user displayname in the room based on their nickname (thanks uhoreg for mucking in there)

  • Improve performance of Matrix -> XMPP gateway messages and joining

  • Improve support for multiple devices for XMPP users connected to the gateway

  • maaaany bugfixes

You can read about (and run!) the latest release over at

Incidentally, if you've not yet, then try joining some rooms such as #twim#[email protected] from XMPP and see it live!

Bruno said:

Hydrogen gained a settings panel this week with a better session backup UX and your end-to-end device information, which should make the manual verification easier. Messages with multiple lines are also rendered as such now, which makes a big difference in usability. The app also works offline again after session backup broke that. Apart from that, several smaller fixes also landed.


Also, image decryption is well on it's way with a prototype working. 🎉


Alexandre Franke reported:

The massive MR to switch to matrix-rust-sdk is still being reviewed and help is still welcome. We have been working on other stuff as well. Actually, since our last news piece for the release of 4.4, quite a lot happened (around 60 commits) that we haven’t reported here yet:

  • Users can now go to the room settings to toggle notifications for each room individually.

  • Rounded corners around everything to match the latest upstream design tweaks (in Adwaita, the official GNOME theme).

  • Many maintainance changes: several dependencies have been updated, cleanups in various places, tightened flatpak permissions for better sandboxing…

And that’s not all! Good progress has been made towards rendering formatted_body. Hopefully that should be merged soon.


Element Web

Ryan offered:

We released Element 1.7.10 on Tuesday with some high priority fixes:

  • Several bugs fixed for both all widgets as well as a few specific to Jitsi call widgets

  • Widgets are now working again in Safari 13.1 (regressed by 1.7.9)

Quite soon after that on Wednesday, Element Web 1.7.11-rc.1 made it's way to staging:

  • Improved state management for voice / video calls

  • Revamped pinned widget UI to support resizing and more flexibility


sorunome told us:

Fluffychat 0.20.0 is out! It should be available in fdroid, google play and on iOS soon!


  • Added translations: Arabic

  • Add ability to enable / disable emotes globally

  • Add ability to manage emote packs with different state keys

  • Add swipe to reply - Thanks @inexcode

  • Initial support for compiling to desktop

  • Initial snap metadata - Thanks @RAOF_47

  • Add latex parsing as per MSC2191 - $tex$ for inline and $$ for blocks


  • Re-scale images in a separate isolate to prevent the UI from freezing

  • URLs without https:// now linkify

  • Parse all URIs, not just URLs

  • emails will linkify now

  • Make sure login to dendrite is working properly


  • Fix amoled / theme settings not always saving properly

  • Show device name in account information correctly

  • Fix tapping on aliases / room pills not always working

  • Link clicking in web not always working

  • Return message input field to previous state after editing message - Thanks @inexcode


MTRNord added:

perfect for university start. Finally I can write the thesis in the University matrix ;P

Element Android

benoit offered:

Element Android v1.0.9 is now available on the PlayStore. For the next release (1.0.10), we will optimize the performance (again!). We already have made some progress when sending a message to a room. We are now working on the crypto module and also we will probably upgrade the Realm database library, which seems more stable now. Besides that, we are still implementing the remaining features with the objective of getting a good feature parity with the other Element Matrix clients.


Manu reported:

This week, we have been working to upgrade libs and tools to be compatible with Xcode 12.

We are making good progress to revive a kind of background sync so that a message appears quicker in the timeline when you tap on its notification. Authentication for widgets is still in progress.


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:

  • Nheko now shows the filename of an image on hover. (Contributed by kamath_manu)

  • Nheko now shows the fontname in the font selection rendered using that font. This makes it easier to know, how the font will look, once you select it. (Contributed by lorendb)

  • Fixed a crash when closing Nheko. While this didn't really cause issues, since you were closing it anyway, it's just bad form to crash instead of exit properly.

  • Removed the membercache. Nheko used to load all members on startup and store them in memory. This made startup slower. Removing it sped up the start by a nice chunk and freed about 30MB of RAM on my system. One step closer to using reasonable amounts of RAM!

  • Fixed excessive clipping when rendering the timeline. This prevented all batching of text messages. Now it only clips the replied to message, which makes scrolling much smoother again!

Finally, some controversial change, which is currently in master but may be reverted at some point: Nheko now automatically forwards keys to verified devices, when they request the keys, without prompting you. While that can be toggled off in the settings, it currently defaults to on. This weakens backward secrecy of e2ee a bit, but it makes it possible to recover from e2ee issues much more easily. Currently I'd argue, that it is an acceptable tradeoff. It is very hard to verify room membership of users at any point in time but the current one and room membership is not verified end to end in any way, so you need to trust the server to provide you with the correct memberlist or you just send keys to verified users. While Nheko still sends keys to all members of a room, when creating the session, it only forwards your own keys to trusted users without prompting you. Currently I think this is an acceptable tradeoff, as opening a popup with "user x wants to have session y shared in room z" is unlikely to be understood by anyone properly either. I'd be glad to hear your opinions though!

That's it for this week, but next week will be interesting too. Lorendb has been hacking on profile support, allowing you to run multiple login sessions of Nheko in separate windows and some other UI features.

Dept of SDKs and Frameworks 🧰


iinuwa reported:

In the past couple of weeks we implemented the last endpoint for the Federation

API. We are working on smoothing out some rough edges in the ruma-federation-api crate, like a few that @Timo addressed this past week, so it will be a little while

before it's completely finished.

We've also created a milestone to track implementation of Identity Service API,

the last Matrix API we have to complete.

Finally, we've created a new Matrix room focused on Ruma development,, focusing the original room on Ruma usage.


kitsune told us:

Quotient 0.6.2 has been released, with a couple of minor bugfixes. This release is used as a foundation of Quaternion beta that's also getting out today - with support of (proper Matrix subset of) HTML, rich text user links (like pills, only lighter), initial Markdown support (if you build with fresh enough Qt), reactions (thanks to Karel Kosek @krkk), navigation to earlier events (thanks to Roland Pallai @rpallai) and quite a few other improvements. To make this release Quaternion had to gain its own basic HTML parser and Matrix-to-Qt-to-Matrix converter, which is likely to end up being a separate micro-library, in the hope that it will be useful for other Matrix projects building on Qt (even non-Quotient ones). A separate call to translators - quite a few strings got updated, so please head to Quaternion project at Lokalise and push the numbers at least to 80%!
