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:

  • No MSCs were merged this week.

MSCs in Final Comment Period:

New MSCs:

Personally I would find that last one quite helpful!

Spec Core Team

In terms of Spec Core Team MSC focus for this week, we're sticking with the same three MSCs: MSC2844 (global versioning), MSC1544 (QR code verification) and MSC2790 (modal widgets). MSC2844 in particular I personally found quite interesting.


Dept of Servers 🏒

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

I have once again updated the Docker ARM Dendrite images for version 0.3.1.

Dept of Bridges πŸŒ‰


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! πŸš€πŸš€ We're only testing it out in a single room but feel free to come by and send a message πŸ˜€ <->

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.

Dept of Clients πŸ“±


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).



Neil said:

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.

Dept of SDKs and Frameworks 🧰


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!) πŸŽ‰

  • 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 DomΓ­nguez 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 πŸ€–

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. πŸ˜‰

  • 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. Putting 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 :)

13.11.2020 00:00 β€” This Week in Matrix β€” Ben Parsons

Matrix Live πŸŽ™

This marks the start of Season 6 of Matrix Live (S06E01), a decision M+A apparently made on the fly just now. Incrementing a mostly-arbitrary counter... Imagine wielding that kind of raw power!

IETF three-way bridge

Matthew reported:

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 πŸ§ͺ

Analysis of the Matrix Event Graph Replicated Data Type

Florian announced:

Fresh off the arXiv presses comes our

β€œAnalysis 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-reviewed 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 U_n = 1000 events and k = 200 servers, we can expect that the width goes below E(U_{n+1}) < 600 events in just one step.*

Dept of Spec πŸ“œ


anoa reported:

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!


Dendrite is a next-generation homeserver written in Go

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.

Synapse Deployment πŸ“₯️


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)

Dept of Clients πŸ“±


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.

Android platform

v1.0.10 is now available on the Play Store. We're also doing ongoing work to catch up with feature parity to Element Web, and Dominaezzz is migrating SDK APIs to suspend functions: no more MatrixCallback!

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!

Dept of SDKs and Frameworks 🧰

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 Ops πŸ› 


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

New Matrix chat bot, Mozilla-focus first

bnjbvr announced:

I've written a small blog post about a Matrix chat bot I've developed with matrix-js-bot-sdk, it was started to address Mozilla specific features first, but then I've added a few other generally useful features too! Hope you'll like it and find it useful! is the room for discussion (thanks Davo)

Dept of Built on Matrix πŸ—οΈ, 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...

Dept of Ping πŸ“

Dept of Status of Matrix 🌑

Open Tech Will Save Us #8 will take place next Wednesday, join us! Calendar event coming soon.

  • Muhammad Radwan, on behalf of Tactical Tech, will present their work on The Glass Room Misinformation Edition. What happens when we increasingly rely on social media and the web for nearly all our information? What information do we see, and what do we miss? How do we know if a picture or a tweet is genuine or truthful? And what can we do if we can’t be sure?
  • Popi from CHATONS will present the work done by CHATONS ("Collective of Alternative, Transparent, Open, Neutral and United Hosters") CHATONS has been initiated by Framasoft, in the wake of the success of its campaign "De-google-ify Internet". A CHATONS member pledges to propose fully FLOSS-based online services, in an ethical and united spirit.
  • Hubert|Uhoreg Chathi will present on the state of encryption in Matrix, and more broadly Why the PGP model is insufficient, what properties we want from encryption (e.g. why we want perfect forward secrecy), how the newer protocols (OTR, double-ratchet, megolm) give us some of the properties we want, and then what's coming in the future (MLS, and what that gives us)

callahad offered:

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.

A major focus of Synapse is being able to meet the performance and reliability needs of massive homeservers like If you're curious about how Synapse's architecture has evolved over the years to meet these scaling challenges, check our our blog post from Tuesday: How we fixed Synapse's scalability!

Lastly, we anticipate releasing 1.23.0 in the next fortnight; keep your eyes peeled for release candidates and let us know if you have any feedback. For a preview of what's coming, check out GitHub for the new commits that have landed on the develop branch since our last release.

PLUS Matthew said:

Synapse now horizontally scales across multiple python processes, as of 1.22: you can configure it so that events are no longer sent through the main proc, eliminating the single biggest bottleneck for large scale Synapse deployments. Read all about it at

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander told us:

Things have been quiet for Dendrite over the last week as I have been working on Pinecone/P2P and Kegan has been working on threading.

That said, a couple of minor changes have been merged:

Eric Eastwood told us:

Exciting visual progress this week with actual bridging between Gitter and Matrix utilizing the virtualUser feature,

we've been iterating on the past couple weeks. Check out the image with all of the user avatars and display name goodness to make both chats on Element and Gitter feel one in the same!

You can also check out the live demo in Matrix Live!


Dept of Clients πŸ“±


Bruno reported:

As mentioned in the sync on Monday, I was mostly distracted from Hydrogen this week. (sorry Bruno -BP) I did release the picture lightbox on Monday, and yesterday managed to close 4 bugs. There's also a community PR for better usability and accessibility in the login screen (keep those coming!) and after some work to make encryption more robust, I hope to do a release with all those goodies tonight.

Check out the demos vid for more Hydrogen!

Manu offered:

This week, we came back to the background sync work to quickly display a notified message in the app. In parallel, we created a profiling tool at the SDK level to track performance like this one.

Element Web/Desktop

Neil enunciated:

We are working through some low hanging fruit around post registration, blank screen interaction prompts and toast tweaks. We are also experimenting with SSO for Meaning that Element will give the user the option of either username/password or SSO. Finally, we are continuing our VoIP efforts and nailing down the designs, checkout Matrix Live for all the details. Next week we'll carry on with post registration UX, VoIP improvements.

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 πŸ‘οΈ Less precise ideas are also welcome, of course πŸ™‚

Dept of Bots πŸ€–

Conduit is a Matrix homeserver written in Rust

Timo announced:

Hello everyone, I have some amazing news to share with you! While Conduit is getting better at federating, Famedly ( has agreed to support me working on Conduit financially. With this news come some organizational changes:

Conduit development now happens at, please submit new issues and pull requests over there. I will update all links in the coming days.

Note: Famedly does not own the project and Conduit will stay free and open source forever!


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 loggingβ€”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.

πŸŒˆπŸŒ‰ Bifrost reaches 0.2.0

Half-Shot reported:

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 :)

Please read the latest changelogs over at and upgrade away!


Eric reported:

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.

Fluffychat 0.21.1 is released!

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

sorunome announced:

It is already in fdroid, google play and ios should follow shortly. We highly encourage people to update, as it contains an important bugfix of sending out way too many key requests, which can cause bad server performance


  • New user viewer

  • Add code syntax highlighting in messages

  • Updated translations: Thanks to all helpers


  • Stories feature removed


  • Fixes sentry

  • Fixes Android download

  • Minor fixes




kitsune reported:

Hot on the heels of beta, Quaternion beta2 is released, fixing a couple of blunders, notably inability to build with external libQuotient. Keep testing, keep translating!


Bruno announced:

Hydrogen can now show images in encrypted rooms! I hope to also release a lightbox feature this afternoon to show a zoomed version of an image.


Manu announced:

This week, we have almost finished the authentication for widgets and jisti in particular. The project is now fully compatible with Xcode 12.

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


Dept of SDKs and Frameworks 🧰

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 πŸ™‚. 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 Availability 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 addresses 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 interesting room to join in the public rooms list. :)

kapina-jaywink reported:

Bubo, the community helping bot-in-progress, gets releases and a new command: breakout. The command can be used to create a breakout room from the current room. Bubo will create the room, invite and make the requester an admin, and confirm in the original room. Anyone who reacts with an emoji to the confirmation will get an invite to the breakout room.

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

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

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. πŸŽ‰


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 maintenance 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

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.

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%!

That is something to love. Come join us in the room to share your news and see what's new from others.

Elokapina (Extinction Rebellion Finland) migrates to Matrix

kapina-jaywink told us:

In recent weeks the XR Finland community has been moving over from Wire to our own Matrix homeserver for encrypted secure chat. This was something that had been planned for a while but kicked off in recent weeks due to Wire suffering from serious encryption key delivery issues, causing messages for many to be unreadable in large groups. Currently we've migrated almost 300 rebels with more to come. Feedback has mostly been very positive, people generally like the Element clients 🀩 One of the interesting changes has been a huge uptick in the amount of discussion, which can be taken as a good sign. The plan is to next start bridging to some of the international XR chapters, for example those on Mattermost, Telegram and Slack. And maybe get them over to Matrix too eventually ;)

To aid in community management, we've started creating a bot called Bubo. Right now it mostly helps with maintaining rooms and allowing mass invites, but more features to help the community cooperate are coming. We were planning to utilize (actual) communities so it has some functionality for those, but decided then to wait for the communities rewrite. It doesn't yet have any releases, will update in coming weeks as features are added and releases made.

kapina-jaywink also

wants to clarify that XR is a decentralized movement and this does not mean other chapters will adapt Matrix - but we can hope and for sure here in Finland we'll be spreading the good experiences to other chapters ;)

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander reported:

We released our first beta last week and we've been busy taking feedback from the community and fixing problems as they have been reported to us. We will be cutting a v0.2.0 release candidate later today, which contains a significant number of important fixes and performance improvements.

We didn't publish a full changelog last week due to the beta announcement, therefore the following list includes changes from the last two weeks:

  • Database migrations are now ran automatically at startup

  • State resolution v2 performance has been improved dramatically on large state sets, seen to be running up to 20x faster in some rooms

  • Dendrite no longer runs state resolution over single trusted state snapshots

  • Monolith deployments with Kafka now work again (each component sets up connections independently to avoid duplicate consumers)

  • Dendrite now correctly rejects invalid UTF-8 - thanks to Lesterpig

  • Fully read markers are now handled - thanks to Lesterpig

  • The completed field is now returned properly for user-interactive auth - thanks to Lesterpig

  • The devices table now tracks last seen timestamps, IPs and user agents - thanks to S7evinK

  • A bug has been fixed in the reverse topological ordering algorithm which resulted in us giving up on inbound references after the first prev/auth event

  • A bug with concurrent map writes in the rate limiting in the client API has been fixed

  • Forward extremities and their previous events are now checked fully against the database

  • Typing events are now ignored if the sender domain doesn't match the origin

  • Duplicate redaction entries no longer result in database errors

  • Some bugs in /send have been fixed where the full room state wasn't requested properly before sending a new snapshot to the roomserver

  • The membership updaters now use database writers properly, which fixes some SQLite locking issues

  • The sync API no longer burns CPU processing unnecessary device key change notifications

  • QueryStateAfterEvents now resolves state from multiple snapshots properly

  • Cumulative room state is now sent to the roomserver when creating rooms locally

  • Missing auth events will now be retrieved from multiple servers in the room if necessary

  • Federation requests now have variable timeouts, allowing us to wait much longer for a remote server to process certain tasks

  • The /send endpoint now returns 500 errors far less often, reducing the frequency that other servers back off from sending to Dendrite

  • Backfill no longer uses the request context for persisting events, which was resulting in us failing to store those events sometimes

  • Invite stripped state from the sync API now includes the stripped invite itself, so that Element Web can display who sent the invite properly

  • The signing key fetch mechanism no longer gives up if it is unable to fetch specific keys

  • Handling of invalid display name or avatar URLs in membership events has been improved

Spec compliance has improved a little:

  • Client-server APIs: 56%, same as last week

  • Server-server APIs: 80%, up from 79% last week

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

Good grief that's a big update! For a video discussion of the status and future of Dendrite, check out Open Tech Will Save Us #7.

Matthew added:

my personal dendrite is now in roughly the same set of rooms as my personal synapse. Dendrite is idling at 180MB of RAM, Synapse is idling at 1.8GB of RAM :)



Hello everyone, this week we merged the federation branch into master. It's not ready to be used properly yet, but we're merging it as it seems stable enough for now. We also improved performance of the federation branch a lot by turning off debug logs.

Other news:

  • I opened two issues on element-ios which currently break register and login support on Conduit, making it completely unusable. Hopefully they can be resolved soon (,
  • I'm working on an MSC for threading. It's still WIP, but you can take a look here:

Thanks to everyone who supports me on Liberapay or Bitcoin!


Neil offered:

Stonking week for Synapse as we landed sharded event persisters and deployed to This is the last significant component other than the main process to go through the sharding process and a major hurdle in horizontal scalability of Synapse.

Initial results look good with event persistence apdex improving, however we think there are still some significant performance improvements available through configuration and will continue to experiment.


We also moved off background processes from the main process. This is significant because it means that while the main process is not shardable it really doesn’t do anything anymore other than orchestration.

Again the initial impact looks very promising and we will continue to tune. Having moved the background processes away it also makes profiling the main process that much easier.


Aside from all of that we continue to progress room knocking put out a 1.21.2 - a bug fix release though please please ensure you are running at least Synapse >= 1.21.0 since 1.21.0 contains a XSS security fix.

Next week we will carrying on tuning and start to look at improving state resolution performance.

Synapse Deployment πŸ“₯️


Ananace told us:

Just pushed the updated image tags and chart version for my K8s-optimized Synapse image for version 1.21.0, as well as a chart update for element-web 1.7.9

then later

And to expand on my previous update, got Synapse 1.21.2 up on the chart and K8s-optimized image.


Pierre said:

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

Synapse integration had been updated to 1.20.1 (1.21.0 available in branch testing)

Element Web integration had been updated to 1.7.8 (1.7.9 available in branch testing)

Dept of Bridges πŸŒ‰

Bridges increase their presence

Half-Shot told us:

Small bit of news I wanted to talk about from Bridge Island. My implementation for MSC2409 has been merged which means appservices / bridges can now listen in for incoming presence, typing and read receipt events! This means that the Slack bridge can now reliably send your typing status to Slack, and Bifrost can reliably bridge your everything to XMPP. The MSC is still in flux and could change, but for now this could really improve the native feeling of bridges :)

(Oh and I should mention anyone using matrix-appservice-bridge v2.2.0+ can use this behaviour for free)

mautrix-python implements Half-Shot's new features

Hot on his heels, Tulir announced:

I've been adding support for the MSCs Half-Shot implemented in Synapse to my bridges:

  • Enabling end-to-bridge encryption now uses appservice login (MSC2778), which means setting up the shared secret login module is no longer required for e2be.

  • mautrix-python has support for receiving ephemeral events via MSC2409 in a branch, which will be merged once Synapse v1.22 is released. After it's merged, /syncing with double puppets will no longer be necessary to bridge ephemeral events.

Both of these will also be implemented in mautrix-go/whatsapp soon.

Now I just need Half-Shot to make synapse send to-device events to appservices, after which bridges won't need any hacky /syncing at all.

Dept of Clients πŸ“±


Bruno offered:

Several releases this week (0.1.11 to 0.1.15) with lots of changes:

  • url-based navigation has landed! All navigation in the app is now done through urls, meaning you can also bookmark any UI state (e.g. grid configurations).

  • fixed 2 memory leaks (exposed now because you can unload your session without refreshing the page)

  • fixed an issue with libolm running out of memory if you send a message to more than 44 devices (see issue #150).

  • some logical additions now we have url navigation: restoring the last url when opening the app with the default route, and a button to close your session and go back to the picker.

  • the app now blocks concurrent access to the same session from different tabs (it just closes the session in the non-active tab). This will prevent multiple syncs tripping over each other writing to indexeddb (e.g. ConstraintErrors and friends).

  • updates are announced in the app (for now through a confirm dialog, but will use an in app notification once we have it)

  • fixes updates not installing on iOS, by having an update prompt. To get this update on iOS though, you'll need to unpin the app, and pinning it again. You'll need to login again after this. All future updates should be installable through the update prompt once you have 0.1.15 though, you won't have to do this again normally.

  • uses the hydrogen icon when pinning on iOS

I really recommend hitting - what great progress!

Element Android

benoit reported:

We are currently preparing the release of the version 1.0.9 of Element Android, which contain searching messages in clear rooms and a lots of other improvements and new features.

The SDK 1.0.9 will also be released, with an updated readme, and a brand new sample app, written by Ganfra. It will help developers to start using the new SDK and can be found here: This sample app is able to let the user connects to an existing account on any homeserver with password login, display the room list, display a room timeline and send message to a room. a brand new sample app

YES! This is the best documentation


Manu offered:

This week, we released 1.0.16 on the App Store (and TestFlight).

Konheko (Sailfish client)

Nico ( offered:

I published the first preview of my Sailfish client called Konheko. While you can run Android applications on Sailfish, they usually are a subpar experience, since they really don't fit the platforms design and style and also usually don't properly send notifications.

So about a year ago I started working on a Matrix client for SailfishOS, but I never really made much progress. Well, last weekend I did, and so it can now send plain text messages as well as various forms of media messages, I made a basic application icon and I've been using it this week already (for unencrypted rooms).

It is still missing a lot of features, but if you want you can install it from OpenRepos. Sources are available here. Just be aware, that it currently stores all messages in RAM, so every restart will take forever to load your rooms and it may run out of RAM at some point. Storing messages in some database will come at some point. Also, a lot of menus may lead nowhere, since those are just placeholders for me atm.



SchildiChat Web/Desktop

SpiritCroc announced:

Recently, I tweaked Element-web to feature a few changes similar to SchildiChat for Android.

For now, it's probably best seen rather as a proof-of-concept than a finished product, as there are still some layout bugs, and no settings available for the added features (I know some people prefer separate lists for direct and group chats). I consider it usable though.

Particular changes compared to upstream Element-web include:

  • A common section for groups and direct chats in the overview

  • Message bubbles

  • Bigger items in the room overview

  • A different dark theme, similar to SchildiChat for Android

I don't know how much I will work on this in the future, but I figured it might be interesting to share either way. Maybe even someone with more web-development skills than me might want to help improving it :)

For further discussion, I have created .

The current version of SchildiChat-Desktop is available for Desktop here, and I host the web variant here. If you want to build it yourself, check out this repo.


Element Web

Neil offered:

Element 1.7.9 has landed, highlights include

  • Many small fixes with edits and replies

  • Fixed a race during cross-signing key upload at registration time

  • Clarified when you have unsaved changes in profile settings

Aside from that has been pushing on with the widgets project. A picture says a thousand words, so here you go.


As you can see T3chguy was really pleased to have me interrupt him to take this picture. Expect the new design to merge next week.

Finally we will most likely ship a new release next week to fix some Jitsi bugs.

Dendrite goes beta

Dendrite is a next-generation homeserver written in Go

kegan told us:

Dendrite has officially entered beta!

It aims to be an efficient, reliable and scalable alternative to Synapse.

We encourage early adopters to try it out starting with v0.1.0 in Monolith/Postgres mode.

Dendrite supports a large amount of the Matrix spec including:

  • All room versions

  • E2E encryption (but not cross-signing)

  • Federation

  • and many others!

We'll be hard at work in the coming weeks ironing out any issues that crop up as Dendrite enters the global

federation of Matrix servers. At present, Dendrite has not been optimised for memory/CPU usage, nor does it fully support sharding, so there is still much scope to improve the already impressive resource usage whilst

heading towards 100% spec compliance.

Spec compliance:

  • Client-Server APIs: 56%, same as last week

  • Server-Server APIs: 77%, same as last week

stefan announced:

I created an AUR package for dendrite. So it is easy to get it running on Arch Linux.


Conduit is a Matrix homeserver written in Rust

timo told us:

This week I worked on a new feature: the Admin Room. This is a room that is automatically created for the first user of a new homeserver. This room will be used to send warnings to server admins in the future and can be used to control Conduit (like querying information, running cleanup, banning servers, hiding public rooms or restarting Conduit). Power levels can be used to control who in the room has access to which commands. The admin room will work over federation, so it's easy to help someone fix his server.

Other news:

  • Federation is now disabled by default and can be enabled in the config

  • Bug with typing notifications is fixed

Thanks to everyone who supports me on Liberapay or Bitcoin!


Neil told us:

This week we put out v1.21.0rc3, which fixes a duplicate messages bug. We expect the full release to go out early next week.

After a long and sometimes painful journey we plan to run sharded event persisters on from Monday. All being well we will start running background processes on their own worker to free up the main process. These two projects combined should noticeably improve performance of and any large scale deployments.

Aside from that we are continuing to work on room knocking as a feature and have been considering ways to reduce load attributable to state resolution.

We will also dust off the notifications project.

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:

This week we finally cleaned up the remaining parts of Chethans GSoC work and merged it. This means Nheko now has partial support for cross-signing. You can either start the verification from another client or when viewing the profile of a user. There are a few things still missing though:

  • Nheko does not use the verification status at all at the moment. So while you can verify your master key and let others verify your master key, from Nhekos perspective there is not much benefit yet. You will however show up with a green checkmark in other clients.

  • While nheko supports verifying your own master key and after that will also let others verify your master key, it does not yet download the self and user signing keys. This means you won't be able to upload cross-signing signatures for your own devices and other users master keys yet. I'll see if I can implement in the next weeks or so (since literally only the private key download or sharing is missing).

  • Nheko can't bootstrap cross-signing yet. This means you need to bootstrap it from Element or another client once. That will probably take a bit until this is complete.

  • The UX is still WIP. Currently it shows a lot of unnecessary buttons, that are a bit confusing as well as not enough green checkmarks, so that needs some work.

Other things that happened in the mean time or are work in progress:

  • Decryption errors should be reduced by a bit now. This is still work in progress though. With device trust landed now, we should be able to do automatic key requests, sharing and key backup soon.

  • Lurkki is currently cleaning up the design of the built in video player.

  • manu_kamath is improving the design when showing images at the same time.

  • LorenDB has been updating our screenshots and working on an Esperanto translation.

  • trilene has been ever busy improving edge cases around the Voip support in Nheko.

So far Hacktoberfest seems to be going well with quite a few people trying to clean up some of the rougher edges in Nheko. If you are using Nheko and think some things could be better, why not try to fix it yourself? October is the perfect time for that!

Featurework of this cycle is also slowly nearing its end. Once cross-signing, voip and the new event store are stable, we plan to improve the UX a bit more as well as some other annoyances and maybe we can do a new release then! A nice and spooky Hacktober everyone!

David Mehren told us:

I just built nheko-git 0.7.2.r2021.517a126a-1 from the AUR and cross-signing works

Highlights include

  • Many small fixes with edits and replies

  • Fixed a race during cross-signing key upload at registration time

  • Clarified when you have unsaved changes in profile settings

Finally, the improved widget support is looking very exciting. Here is a design grab to give you an idea of what to expect. Note this is not a real Element screen shot, the base functionality is there, but the look and feel of the final version is subject to change.


Michael (t3chguy) added:

Matrix VoIP Tester

reivilibre said: (updated demo:

This week, I have improved the scoring rubric, so that the verdict given to you by the tester more accurately reflects the likelihood of connection establishment.

I have also added more hints on what the verdicts mean.

Finally, I have added workarounds to support Chromium browsers that decided to break their WebRTC API so that they could pedantically rename ip to address. In any case, it now seems to be on par with Firefox.

The VoIP tester is now roughly 'usable' but please note that IPv6 support is totally untested (I don't have IPv6) β€” it is also suspected that some browsers won't try IPv6 anyway.

There are also some more features on the wish list, such as screenshot safety and extra help when things go wrong.

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

jplatte said:

This week, q-b implemented moderation policy events, bringing us to full compatibility with r0.6.1 of the client-server API. iinuwa added the only endpoint we were missing from the appservice API. Additionally, I improved Ruma's JSON canonicalization, making it both simpler and more efficient.

Due to two issues regarding future-compatibility, we're still a while away from our next set of releases, but we're working on it!

New library: ObjMatrix (Objective-C)

js introduced it with:

ObjMatrix (GitHub) is a new Matrix client library written in modern Objective-C for ObjFW. Because it uses ObjFW, it is not limited to Apple platforms, and instead is extremely portable and should run on basically everything.

This is currently in its very early stages and is intended to be suitable to develop bots and clients with very soon. Being suitable to develop bridges with it is another goal for later.

Since ObjFW also works on platforms that are usually hard to support or port software to (e.g. MorphOS), this will hopefully also bring clients for these less mainstream operating systems. I'm especially hopeful about MorphOS here, since ObjFW already runs quite well there (parts of it are included with the OS even!), and hardware on which MorphOS runs on is usually not powerful enough to run Element Web. And eventually, I will want to have a Matrix client on my Amiga, too πŸ˜‰ (which this should enable).

This currently does not have a decicated Matrix room yet, so all discussions about it currently happen in So please feel free to join there and follow along development. And contributions are of course very welcome!

Element review by TechRadar

TechRadar have published a fairly thorough Element secure messenger review. This covers the Web, Android and iOS clients, and appears to use the server for signup.

The review is very positive, awarding 4.5/5, and concludes:

The Element messenger platform scores highly for its approach to security and its commitment to decentralization, and it's definitely going to be of interest to businesses wanting control over their own chats – as well as plenty of individual users as well.

Dept of Servers 🏒


Neil announced:

This week we put out two point releases to fix critical bugs. At the very least ensure that you have upgraded to 1.19.2 which is a security release but you may as well go the whole hog and upgrade to the hot off the press 1.19.3. We will release 1.20.0 early next week.

Aside from that we continue to work on performance analysis and the sharding of the event persister continues - it’s proving to be a really tough job but we are getting there. We’ve also been making progress on the room knocking implementation

This week we say goodbye to Oliver (reivilibre) as a leaving present he fixed a long standing bug that prevented servers catching up after a federating outage and as we speak is furiously trying to finish a service to test TURN configuration. Thanks Oliver!

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander said:

Not much has happened this week, as the Dendrite team have been taking some time off. However, we still have a couple of changes to report:

  • Support for rejected events has been merged

  • Work on soft-fail has begun (although not complete yet)

  • A new mechanism for avoiding SQLite parameter limits was contributed (thanks HenrikSolver!)

Spec compliance is on the up:

  • Client-Server APIs: 56%, same as last week

  • Server-Server APIs: 74%, up from 71% last week


Conduit is a Matrix homeserver written in Rust

timo announced:

Welcome back! This week we made some groundbreaking progress - this is not a joke, we found a bug in Synapse while breaking multiple Matrix rooms, causing the Matrix team a lot of unnecessary stress. Let me explain: The good news is that Conduit is starting to federate now. This means that you should be able to join all public rooms of the Matrix network and exchange messages. Note that Conduit does not do all the checks it should be doing yet making it stop sending messages from time to time as well as that advanced features like loading the history, syncing temporary data like read receipts or accepting invites are not implemented yet.

The bad news is that, while Synapse is happy to accept Conduit's messages when it is already part of the room, joining into one of the rooms Conduit servers are part of didn't work because of an event validation bug. The Matrix team did an excellent job at fixing this bug and releasing a Synapse patch the same day, but the damage has been done making a few rooms inaccessible to old Synapse servers. Thanks to everyone who supports me on "Liberapay" ( or Bitcoin!

Synapse Deployment πŸ“₯️

Synapse on NetBSD

js reported:

I ported Synapse + its dependencies to NetBSD and it is now in pkgsrc as chat/matrix-synapse. This means that Synapse is now easily installable on any operating system that supports pkgsrc (which is many, e.g. NetBSD, Linux, macOS, Solaris, AIX, Haiku, …). And while at it, I also ported mautrix-hangouts + dependencies (in pkgsrc as chat/mautrix-hangouts).


Pierre told us:

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

Synapse integration had been updated to 1.19.1 (1.19.2 available in branch testing)

Element Web integration had been updated to 1.7.5 (1.7.7 available in branch testing)


Ananace offered:

Both image tags and a new chart version are hereby pushed for 1.19.2 for my Synapse image and Helm chart

then later

Just pushed the updates for the K8s-optimized Synapse image and chart for 1.19.3

matrix-appservice-bridge hits 2.0.0ʳᢜ¹

Half-Shot said:

Hey bridge developer enthusiasts! Myself and ChristianP (bridge crew of have been working hard on freshening up the matrix-appservice-bridge library. It's no secret that it was using "classic" Javascript rather than ES6 syntax, was poorly documented in places and there were no types at all to make use of.

But that's all changed now, the 2.0.0-rc1 release brings fresh types, new convenience methods, a total swichover from Bluebird Promises to native Promises and much much more. If you are looking to quickly get set up writing bridges, it's never been easier.

Check out the slack-starter project to get your first taste of bridge excellence and see what you think.

As this is an RC, feedback is valuable and logging bugs helps us all. Please do so if you encounter any issues πŸ˜„

Bridge Encryption Support

Half-Shot reported:

Hi encryption fans. This week the bridge team has been churning away at adding support for encrypted rooms in the matrix-appservice-bridge library, to enable support in matrix-appservice-irc, matrix-appservice-slack, and anyone else using the library. This is probably the most exciting feature the library has seen in a long time!

The feature will be a simple config toggle, so existing bridges will have to do very little work to support it.

The first phase plans to use Pantalaimon with bridge users syncing like real users, but eventually the hope is that this will be all built into the library. Come check out this issue to keep track of progress.

Dept of Clients πŸ“±

Element Web

Neil announced:

  • Released 1.7.6 and 1.7.7 highlights include

    • Redesigned right panel where top right actions are now revealed via the i icon

    • Widgets can now be opened in the right panel

    • Widgets won't be visible in the Apps Drawer (top of timeline) by default (except Jitsi) - you need to pin them from the right panel

    • Widgets can now be resized

  • A new feature to defer e2ee set up until the user actually wishes to use an e2ee channel.

  • A series of config flags to remove various features from the UI thereby simplifying the experience.


miruka said:

0.6.3 and 0.6.4 were released this week, and I'm now working on desktop notifications support and push rules control.


  • Add a system tray icon.

    A left click will bring up the Mirage window, middle will quit the application and right will show a menu with these


  • Add a closeMimizesToTray setting to the config file, defaults to false.

    Controls whether closing the Mirage window will leave it running in the system tray, or fully quit the application.

  • Add a discrete read marker indicator to messages, shows how many people

    have this event as their last seen one in the room.
    A way to see who read the message and when will be added in the future.

  • Themes: add chat.message.localEcho and chat.message.readCounter color properties

  • Add a zoom setting, defaults to 1.0

  • Add a lexicalRoomSorting setting, to sort rooms by their name instead of

    recent activity.
    A restart is needed to apply changes to this setting.


  • Restrict Mirage to a single instance per config folder, trying to launch a

    new window will instead focus the existing one.
    The MIRAGE_CONFIG_DIR and MIRAGE_DATA_DIR environment variables can be

    set to run different "profiles" in parallel.

  • Reduce the visible lag when opening a chat page, switching rooms should be

    a lot smoother

  • When using the focusPreviousMessage and focusNextMessage keybinds, if no

    message is focused and the timeline has been scrolled up, focus the message in the center of the view instead of returning to the

    bottom of the timeline and focusing the last one.

  • Don't re-center the room list on clicks by default.

    This prevents the list from jumping around every time a room is selected.
    The previous behavior can be restored with the new centerRoomListOnClick


  • Show a better terminal error message than "Component is not ready" when the

    window creation fails, giving details on what went wrong in the code

  • If an account's access token is invalid (e.g. our session was signed out

    externally), say so with a popup and cleanly remove it from the UI, instead of spamming the user with errors.

  • Rename message context menu option "Debug this event" to just "Debug"

  • Unify up/down and (shift+)Tab navigation for the account Sessions page

  • Changes to the UI scale/zoom via keybinds are now persisted across restarts

  • Themes: uiScale is now bound to window.settings.zoom.

    This change is necessary to keep the zoom keybinds working.


  • A bunch of stuff, see the full changelog for 0.6.3 and 0.6.4

Element Android 1.0.7

benoit offered:

Element Android 1.0.7 has been released (still stuck in Google pipes writing those lines), and will be quickly followed by 1.0.8 to fix a problem with cross signing verification.

We are working to implement search of messages in a room and we keep on fighting bugs and improving performance of the application.

We are also iterating on the home screen, to improve user experience, and try to satisfy users with a few rooms as well as users with several hundreds of rooms.


Manu said:

This week, we released 1.0.12 with several bug fixes including the one for background crashes due to PushKit


Bruno told us:

Released 0.037 on Monday with some polish for E2EE:

  • remove outdated devices when querying

  • update room summary with decrypted events, also when retrying decryption

  • various crash protections

  • keep megolm session with earliest index when receiving a room key we already know about

  • add new icon

  • fix issue where olm would be loaded twice when login failed

  • show decryption errors in timeline

  • show encryption enabled tile in timeline

The rest of the week was implementing session backup, which I hoped would be ready to release today but it needs some more polish unfortunately. In the meantime, here's a GIF teaser:



Thank you to Krille, who told us:

FluffyChat version 0.18.0 is out now in F-Droid, Testflight and soon the PlayStore:


  • Added translations: Armenian, Turkish, Chinese (Simplified), Estonian
  • Url-ify matrix identifiers
  • Use server-side generated thumbnails in cleartext rooms
  • Add option to send images in their original resolution
  • Add additional confirmation for sending files & share intents
  • Add option to opt-in to report issues / crashes to sentry
  • Write keys to online key backup, fully implementing online key backup


  • Tapping links, pills, etc. now does stuff
  • Better handling of sending messages in bad network
  • Better recovery of "keys not cached"
  • E2EE is enabled again


  • Various html rendering and url-ifying fixes
  • Added support for blurhashes
  • Image viewer now eventually displays the original image, not only the thumbnail

Hemppa the bot is a multi-purpose Matrix bot for writing new functionality easily with Python.

Cos said:

Hemppa gained a small but big feature for making fediverse better: per-room Mastodon tooting support. This means that you can set up a Mastodon account in your room and anyone with moderator rights can toot to that account. This way you and your roommates can super easily send toots to the world directly from Matrix. Mastodon (unlike the big alternative) supports RSS feeds out of the box so it's very easy to subscribe to users and hashtags with stock RSS bot. Toot #hemppathebot if you like it! Another new contribution worth mentioning is welcome which can send welcome messages to users registering on the server or joining a room.


Ananace said:

Another week, another Ruby SDK release. This time adding a little fix to avoid duplicate state events being passed twice to the application if identical ones arrive in both state and timeline, also adds a global state event handler and moves room event handling to not depend on room instances themselves.

Asked how much the SDK is used in production, Ananace said:

a little, we've hooked Matrix into our server orchestration / configuration management system TheForeman - which is a Rails application. Also got a colleague who's doing a bot to linkify internal ticket IDs.


iinuwa told us:

Thanks to @q-b and @jtescher we have implemented more of the federation endpoints (bringing us up to about 85% completion) and every (one) endpoint of the Push Gateway API!

We fixed a bug where federation endpoints expected access tokens instead of server signatures for authentication. In the future, we may add an API that requires signatures on requests.

Finally, we've also continued progress on the non-exhaustive type updates for backwards compatibility; we expect to finish this within the coming weeks.

Matrix Reminder Bot

anoa announced:

v0.2.0 of matrix-reminder-bot has been released! This releases includes lots of bugfixes, updates and polishing. Find the list below:


  • Better support for command prefixes other than the default !.

  • Just writing !silence now silences the currently active alarm.

  • The bot will now print the correct syntax of a command if the user fails to follow it.

  • The bot will reply to events if it cannot decrypt them, as well as offer helpful tips that both the user and bot operator can try to fix things.


  • Timezones. They should finally work correctly! 100% guarantees though.

  • Alarms were a bit broken. They're fixed now.

  • Fix commands with formatting and newlines not being picked up by the bot.

  • Fix non-latin characters preventing reminders from being deleted.

Internal changes

  • Add a dev-optimised Dockerfile for quicker iteration during development.

  • Better wording revolving alarms. They're just reminders that alarm repeatedly when they go off.

  • Log why the bot is unable to start.

  • Don't print "Unknown help topic" in case the user is trying to ask another bot for help.

  • The config dict is now a singleton.

  • Type hints everywhere!

Additionally, the minimum Python version is now 3.6. matrix-reminder-bot is made with nio-template.

Dept of Ping Extra:

timo announced:

Normally the ping shows how long other servers take to receive the sending-server's message. Some servers receive it quickly, some take hours. All this flows into the statistic of the sending server. I wrote a small program that's the other way around. Instead of measuring the sending-server's ping, it associates each measurement with an echo-bot (instead of the sending server), so this plot shows which maubots are the fastest to respond (it's probably not accurate at all, because most of the pings were started on conduit servers this week, but it's interesting nevertheless):

We had another long overdue Spec Core Team retro this week. On the whole it felt very productive, and we've hopefully helped identify some key issues and actions going forward to help internally organise the way the team spends time on MSCs (read: unblocking review progress from the team).

We're still working out our exact strategy asynchronously at the moment, so expect more details to follow soon.


Dept of Servers 🏒


Neil reported:

This week we put out a new release candidate for Synapse 1.20.0, highlights include shadow ban support, more async/awaiting and unread message counts being added to sync responses to support upcoming notifications work.

Aside from that Erik has been continuing to get event persistence sharding ready for shipping. He already has a working version, but currently all workers will run at the speed for the slowest instance. Once that is fixed we will put it on to see how it performs.

Patrick has finished up on asyncing all the things, and is now studying flame graphs to figure out where all the cycles on the main process are going.

Andrew has been taking a look at the knocking MSC, expecting concrete progress in the next few weeks.

Brendan has been working notifications support and is currently in VoIP land helping Dave on trying to level up our VoIP support.

Finally Oliver has dusted off his TURN tester from last Summer to get it working before he returns to university. The idea is that it will act a bit like the federation tester for but for TURN configuration.


Conduit is a Matrix homeserver written in Rust

Hi everyone, Devin R and I are working on state resolution, hopefully we have something exciting to show you next week. I also worked on the remaining key backup endpoints, so for example deleting backups works as expected now. Thanks to everyone who supports me on Liberapay or Bitcoin!


Dendrite is a next-generation homeserver written in Go

kegan told us:

This week we have been continuing work on the beta task list:

  • The current state server has been removed.

  • Joining rooms over federation is now more reliable as a single faulty event will no longer fail the request.

  • Support for database migrations has been added.

  • Various bug fixes to reduce the number of database is locked errors on SQLite.

  • Experimental support for peeking has been added - See MSC2753

  • DENDRITE_TRACE_SQL will now additionally trace unsafe goroutine writes that do not use ExclusiveWriter.

  • The README has been updated with hardware requirements.

Spec compliance remains the same this week:

  • Client-Server APIs: 56%, same as last week.

  • Server-Server APIs: 71%, same as last week.

It's been a big week for Bruno:

Released 0.0.36 with end-to-end encryption enabled! πŸŽ‰
Most of this week was spent on performance improvements for IE11, where asm.js runs quite slow. Decryption is run in parallel on 4 workers in that browser, giving a massive speed-up and added responsiveness (the UI would freeze for 7 seconds when opening a room prior to this). There is still some polishing to do on sharing room keys, which I will get to next week, but all in all, it should work well. Next week I also want to get started on supporting key backup, so you can also read your encrypted history from before you logged in.

Element Web

Neil (same fellow from earlier) reported:

Element 1.7.6-rc.1 is now available at

  • Redesigned right panel where top right actions are now revealed via the i icon

We have released Element Android 1.0.6. Now we are working on sync mode for F-Droid version of the application (i.e. without FCM). We are also improving the experience with 1-1 calls.

SchildiChat for Android

SpiritCroc said:

Element v1.0.6 has been merged into SchildiChat.

Furthermore, following Schildi-specific fixes and improvements are included in the latest update:

  • Fixed message bubbles clipping italic text

  • Less wasted bubble space in some scenarios

  • Deleted messages are now hidden by default in the chat overview

  • Display the year in the chat list for old chats

  • The inclusion of chats without notification in the overview's unread counter, which I added last week, is now optional

To be clear, Element v1.0.6 has been upstreamed into SchildiChat, the projects have not merged.


Manu told us:

This week, we released 1.0.10 which provides PIN protection and the return of the incoming native call screen. Then, we started to update room creation flows with new icons and behaviors for creation buttons and a new screen for room creation.

Maunium sticker picker

This isn't strictly a client, but it's in the clients section.

Tulir announced:

Getting stuff into the spec or even implemented in Elements is very slow, so while we wait for proper native sticker packs and pickers (i.e. not in an iframe/webview), I decided to make a better sticker picker widget:

The goal is to be as fast and simple as possible. The picker and sticker packs are just some static files that can be served anywhere (no compilation required). It doesn't require self-hosting anything except said static files, and it has been confirmed to work on all three Elements.

There's a Telegram import script that's used to reupload stickers to Matrix and generate the static sticker pack files that the picker widget uses. It's technically also possible to make the sticker pack files yourself, but there's no easy way to do that yet.

Due to the simplicity of the picker there's no authentication, which also means everyone sees the same sticker packs. One way to get around that limitation is to have a unique URL for each user. I'll probably write a bot to manage copies of the picker for multiple users in the future.

Other future improvements include remembering frequently used stickers (surprisingly, all three Elements keep localStorage for widgets), importing Telegram animated stickers and searching for stickers by emoji/name

later more words appeared from Tulir:

Since the initial announcement, my sticker picker has received some more features:

  • Added a slider to configure the number of stickers shown per row

  • Frequently used stickers now show up at the top

  • Imported all the packs from Scalar (the default integration manager)

A model of productivity, Tulir also announced:

my sticker picker has dark theme support too now

Just bumped the Matrix Ruby SDK to version 2.1.2, fixing another bug with server discovery as well as the fact that state events haven't been provided for the application using the SDK. Oops.


Lieuwe announced:

matrix-appservice-rs got some love!

Though still a long way to go before it is comparable to the likes of matrix-appservice-node and matrix-appservice-bridge, I did improve some little things.

  • Updated to the latest (git) version of Ruma, and only depend on ruma instead of all subcrates.

  • Small memory improvements: using references in MappingId and shrinking the MappingDict when initializing.

  • Some more documentation.

  • Cleaned up the code a bit.

There is also now a specific room for this crate:, feel free to ask for support or tell if you've suggestions.

Next step in world domination

Alexander Olofsson reported:

The Matrix service at LinkΓΆping University has now passed its soft launch state and headed straight into full and proper deployment territory. (Though we're still not being overly vocal about it, don't want to crash our deployment on day one after all.)

They're simply announcing it on TWIM, perhaps the most high-profile place in the world!

We're doing a little bit of advertising of it to computer clubs and the like though, to slowly build up the users.

But then:

And just to add another slight update: already we have at least one conference planning on trying out the new Matrix server as well, so the user count might just end up exploding soon anyway.

Spec Core Team

In terms of Spec Core Team MSC focus for this week, we're sticking with the widget theme, but also adding something new. Travis is writing up a mahoosive widgets PR in addition to some widget MSCs. We're also adding on MSC2753 (peeking /sync), MSC2444 (peeking federation), which will both unlock some very exciting upcoming features (such as x-as-rooms)!


Dept of Servers 🏒

Erik has made an initial, naive implementation of a sharded Event Persister worker - the non-sharded version currently being one of the biggest bottlenecks on right now. It still needs a bit of polish to be production ready, and Sytest will need some updating to support testing it, but otherwise progress is looking good!

Brendan is polishing his unread counts implementations, while Rich is writing up the push rules replacement tech in an MSC. Rich has also been optimizing the device code in Synapse to both simplify the code, as well as cut down on unnecessary device data being sent over federation.

Patrick has finished converting Synapse's database code to be fully async! This has the benefit of making profiling the Synapse process much more sane, and we're already starting to find a few little places where Synapse is burning CPU unnecessarily! Now, Synapse won't be fully async'd until Twisted itself is, and we drop support for older Twisted versions that aren't, which is not soon. However the majority of the code that developers touch and that is executed being async has massive benefits either way πŸ™‚

Andrew has been working on having a confirmation pop up after users click the link in their email, to help prevent phishing scams. He's also trying to finally make Synapse spec-compliant in accepting identifier dictionaries during user-interactive authentication.

Olivier has been continuing to help Synapse recover missed messages better after it has been offline for an extended period of time, as well as various fixes to push.

Expect a fresh release with all these changes soon!

As someone who had my own server outage this week I'm looking forward to seeing this!

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander said:

This week we have been continuing on our bug-hunt mission and have been working on refactoring some significant parts of the codebase to simplify the API surfaces and avoid race conditions.

Changes this week include:

  • The current state server is in the process of being deprecated, with this functionality being folded into the roomserver

  • Support for rate limiting on certain CS API endpoints has been added

  • Support for password changes has been added, allowing users to change their own password

  • /sync no longer incorrectly lists some rooms in the leave section, which caused problems with Element Web and other clients

  • Roomserver input events are now handled in FIFO order with per-room workers

  • Roomserver input, query and perform packages are now split up nicely

  • The federation sender and keyserver now delay some startup tasks to allow the HTTP listeners to start more quickly

  • The federation sender is now used for backfilling and getting missing events

  • Some more SQLite writer bugs have been fixed

  • Room information in the roomserver is now handled in a common structure

  • The public rooms API now correctly searches remote servers (thanks rohitmohan96)

  • Initial support for Peeking (MSC2753) and Peeking over Federation (MSC2444) is in progress

Spec compliance is improving:

  • Client-Server APIs: 56%, up from 55% last week

  • Server-Server APIs: 71%, same as last week

Last week, we updated some of our documentation and created a whole new set of easy first issues and medium to hard issues for contributors.

If contributing to Dendrite sounds like something you would be interested in, please take a look at these issues and join us in! There's also for general Dendrite chat and updates.

Synapse Deployment πŸ“₯️


Pierre announced:

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

Synapse integration had been updated to 1.18.0 (1.19.1 available in branch testing)

Element Web integration had been updated to 1.7.4 (1.7.5 available in branch testing)

Dept of Bridges πŸŒ‰


Lieuwe told us:

Introducing a new bridge to the family, tomsg-matrix!

A friend of mine preferred using his own chat protocol, but having a chat protocol is useless without having people to talk to. Since I prefer using Matrix I thought it would be a fun exercise to try and create a bridge using Rust.

The bridge uses the newly created (still very WIP) matrix-appservice-rs. A Rust library that builds on top of the Ruma suite, the goal is for it to be comparable to matrix-appservice-node and matrix-appservice-bridge.

The code for tomsg-matrix is open source, but be prepared, I hastily pushed it to GitHub without cleaning it up.

Come chat to us over at, hoping that it doesn't break. :P

Making your own chat protocol in a world of well established options seems, frankly- oh right.


Benedict told us:

We are currently working on an Android-App to use an old smartphone as SMS-Gateway for matrix-sms-bridge, because using gammu in production (>50 SMS/day) seems not to be very reliable with our USB-modem.

im_sender_service, for zabbix bridging and more

progserega said:

I create service for sending corporate information: some service (for example zabbix) can send message to this service (over http-api) and service will create room (if needed), invite user and send message to this room. Service will change status of message in his database to readed when user will read this message. Also service can send any changes statuses of this message by callback url. Editing old messages also supported: for example zabbix can send UID problem to this service and it is will edit old "problem message" to "problem resolved".


Dept of Clients πŸ“±


Ditto is a Matrix client for iOS & Android

Annie offered:

Ditto development is back from hiatus!

I'm currently in the process of rebuilding Ditto - partly to incorporate rn-matrix, and partly to support a WEB VERSION

The new repo can be found here ( (there's a new repo mostly because getting react-native-web to play nicely with the rest of the app was a challenge, to say the least)

As a sneak peek, enjoy this rough version ( of Ditto for web :)

Expect to see what I'm calling Ditto's 2.0.0 drop on TestFlight and Google Play in a few weeks.


Matrix Room

Big exciting things happening!


Bruno offered:

Good progress this week, I just got end-to-end encryption working. The code still needs some cleanup and polishing to be able to release it in the wild, but expect a release somewhere next week with E2EE enabled.

YESSSS - see Matrix Live for a demo.



gomuks is a terminal based Matrix client written in Go. Source on GitHub

Tulir said:

gomuks now supports importing and exporting message decryption keys. It even supports exporting the keys for a specific room, e.g. for sharing them with someone else. To help with sharing exported key files with someone else, gomuks also got support for uploading media.

Next I'll try to figure out how nikofil's cross-signing/SSSS PR for mautrix-go works and use that in gomuks.

v0.2.0 was just released with these features!


eric told us:

NovaChat is a new Matrix-based desktop client that aggregates all your chat networks into one app. We now have integrated bridges for Whatsapp, Twitter, Telegram, Hangouts, Slack, Messenger, Android Messages (SMS), Skype, Discord, Instagram and IRC.

Sept 4 Updates:

  • Continuous UI improvements. Everything is much denser now. See screenshot below.

  • New bridge alert: tulir just completed an Android Messages SMS bridge (which is a total hack but it works!) for NovaChat.

  • Added Discord Bridge. Thanks for building this Sorunome!

In the works...

  • Still working on our iMessage bridge, using jailbroken iPhone 4s

  • Marking messages as 'unread'

Sign up for the NovaChat beta. Or send me a DM!



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:

  • Lurkki added an emoji completer to the message area! This was a super requested feature and it is pretty awesome, that someone picked this up and implemented it! This means you can finally write :fire: and have it expand to πŸ”₯! Seems like this will also lead to a few more improvements to our other completers down the line (user, room, etc completions), so thank you very much Lurkki!

  • I've been mostly reviewing PRs this week (and trying to get some other work in line, like MSCs, synapse stuff, etc). With this hopefully Chethans work on cross-signing will be merged soon, which will give us most of the building blocks to have cross-signing in Nheko (his work is basically only missing Secure Secret Storage and Sharing). We hope to fix the few remaining build issues in the next week or so.

  • On the side I have been cleaning some UI stuff to simplify our room settings dialog and allow advanced users to hide/show certain event types in the timeline. This will probably take a bit more time to be finished though.



sorunome offered:

Fluffychat 0.17.0 is released!

IMPORTANT: Due to legal reasons (USA cryptography export), end-to-end encryption has been disabled in the google play and ios builds for now. They will be re-enabled once we got all that figured out.

The F-Droid builds still have e2ee. As the play store and fdroid builds use the same build signature, you can simply install the fdroid version over the other one. More information on that here:


  • Pin and unpin chats

  • Implement event aggregations

  • Implement message edits

  • Render reactions

  • Add / Remove reactions by tapping on existing reactions


  • Don't re-render the room list nearly as often, increasing performance

  • Various fixes for sending messages on bad networks

  • Design tweaks and fixes

  • Various performance fixes and improvements

Definitely hoping to see these issues resolved.

SchildiChat for Android

SpiritCroc offered:

I removed SchildiChat from the Google Play for now, due to the complications of providing encryption-capable software from US servers. Huge thanks to the FluffyChat team for providing insight into their investigations concerning the US export regulations!

On the positive side, SchildiChat is now finally available on F-Droid from the official repos.

Furthermore, I have set up my own F-Droid repository, where you can get updates that are compatible with the Google Play Store variant and which support push notifications.

On the implementation side, I can report the following:

  • Element 1.0.5 has been merged

  • The "low priority" category now remembers its expand/collapse-state across restarts

  • New setting to hide member state changes and reactions from the chat overview

  • The category unread counter badge now also displays the number of chats with new messages in case none of these has notifications enabled


Manu announced:

This week, we should have fixed the background crash that was happening in TestFlight 1.0.7. TestFlight 1.0.9 has been submitted yesterday.

In parallel, we started to modernise the AppDelegate class, the entry point of the app. This is the very first step of several improvements we want to do (this is not only to rewrite it in Swift).

Element Android

benoit reported:

We have just merged a few big PRs to develop: add emails and phone numbers to Matrix account, rework of upload attachment management, and other stuff related to 1-1 calls. It will live on develop for the week-end and we will prepare the release v1.0.6 at the beginning of next week.

Dept of SDKs and Frameworks 🧰


rn-matrix is a React Native SDK for matrix

Annie offered:

Built on the matrix-js-sdk, this NPM package will help any React Native developer drop matrix into their app.

Been working on this since the beginning of the summer - this package is split into two, one for the data and one with default UI components for those who want to drop chat into their app quickly (not required).

Would love feedback on docs, installation, and usage, so try it out and drop me a line!

NB, this update should be read together with the Ditto update above


iinuwa said:

Over the past couple of weeks, jplatte has been hard at work making sure we can introduce new fields to request and response types as non-breaking updates. Thanks to @nicholaswyoung, consumers can opt-in to breaking changes to ensure compliance with the spec on each update.

Besides that, we implemented another endpoint for the Federation API, bringing us up to 20/31 endpoints implemented.

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

Slavi reported:

matrix-docker-ansible-deploy can now help you set up matrix-registration - an application that lets you keep your Matrix server's registration private, but still allow certain users (those having a unique registration link) to register by themselves.

See our Setting up matrix-registration documentation page to get started.
