Matrix Live πŸŽ™

Dept of Spec πŸ“œ

anoa announced:

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:

  • No MSCs are in FCP.

New MSCs:

Spec Core Team

In terms of Spec Core Team MSC focus for this week, we're taking off MSC2674 and MSC1544 while the author works through feedback, and instead looking at getting widgets in line.

The spec for widgets has so far lived on a collaborative document that hasn't been updated in some time. As a result multiple, separate implementations have sprouted. We'd like to nail this down. So the focus for this week will be: MSC1960 (widget auth mechanics) and MSC1236 (general widgets).


Dept of GSoC πŸŽ“οΈ

The coding phase of Google Summer of Code is over! That said there is still a bunch of stuff to do, code is still appearing and we're now entering the time of many forms to fill in in order for people to get paid.

A little pre-emptive, but wow it's been a good summer! SIX students, all did well!

matrix-ircd - Call for Testing

jplatte announced:

GSoC coding is over and there's now an async/await ported matrix-ircd! Before merging that into master, it would be nice to have it tested a bit more. To install it, you first need Cargo, Rust's package manager (Installation). With that set up, just run

cargo install --git <> --branch async_await

Once matrix-ircd is installed, you can run it and connect to the locally spawned server with any IRC client.

HTML embeddable matrix chat

arnav-t said:

For the GSoC project HTML embeddable matrix chat this week -

  • Added an 'auto' option for the theme (read and set the theme from the device)-

  • Added a 'custom' highlight color (meant to be modified by users).

  • Restyled various components.

More news to come from this project - going to be used in a really exciting live event in the near future. Arnav has accidentally found a niche. :D

One more thing: This project needs a new name (riot-embedded I don't like.) If you have ideas you can fling them at arnav-t or post in

Dept of Servers 🏒

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander told us:

This week has mostly been focused on beta milestone tasks and bug fixes. Changes this week include:

  • Joining rooms which the server already belongs to when invited by a user from another homeserver is now significantly faster

  • The client API no longer refers to the device DB directly, instead using the new user API

  • A number of locking issues have been fixed in the federation sender

  • The /join endpoint now accepts ?server_name=... query parameters

  • The device list updater now obeys the backoff period and blacklisted status from the federation sender

  • Uploaded media will no longer be truncated to 0 bytes when max_file_size_bytes option is set to 0 (for unlimited)

  • The media API now correctly cleans up temporary directories when errors occur

  • The media API now returns unique media IDs and metadata when multiple users upload the same file, whilst maintaining deduplication on disk

  • Rejecting invites over federation multiple times should now work properly

  • Redactions are now permanent and are committed to the database

  • Some caches have been added to the roomserver for room IDs, state key IDs and event type IDs to reduce pressure on the database

  • The redaction endpoint is now spec-compliant

  • Some places where global errors were overwritten have been fixed (thanks oliverpool!)

  • Some state key checks in the roomserver membership updaters have now been tidied up (thanks oliverpool!)

Spec compliance has improved slightly:

  • Client-Server APIs: 55%, up from 54% last week

  • Server-Server APIs: 70%, down from 71% last week due to a single flakey test

We've also 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.


Conduit is a Matrix homeserver written in Rust

timo said:

Some new features this week!

  • Handle transaction ids to avoid duplicate messages on bad connections

  • Redaction reasons

  • Add remaining key backup endpoints (e.g. deleting backups)

  • Send correct device list changes when leaving and joining e2ee rooms

Also check out our new website ( if you haven't already.

Thanks to everyone who supports me on Liberapay or Bitcoin!


anoa offered:

This week Erik has been working on sharding the Event Persister worker as we aim further for horizontal scalability for Synapse. Some of the complication comes from ensuring that sysadmin's don't misconfigure things where multiple event persisters persist events in the same room.


Patrick has been continuing on the async/await train and has just submitted the final PR which async's our runInteraction method - the one that most database calls go through. Synapse is nearly 100% async! He's also been submitting a flurry of shadow ban PRs, which will be another powerful tool for moderation.

Brendan and Rich are continuing to work on the Notifications rewrite, with Brendan finishing up unread counts, and Rich polishing up designs for the new replacement for push rules.

Andrew (who dat? - ed.) is continuing to work on the knocking MSC and has fleshed out the CS and SS details. There are still some open questions though, so please give feedback if you notice anything off!

Finally, Olivier has been working on making sure you get your missed messages when your homeserver has been offline for a while, as well as various Sygnal fixes and matrix-synapse-ldap3.

Them's the news!

Synapse Deployment πŸ“₯️


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 1.18.0 (1.19.0 available in branch testing)

Element Web integration had been updated to 1.7.3 (1.7.4 available in branch testing)


Ananace told us:

Just pushed an update to my matrix-synapse chart, fixing the volume permission configuration - for those who want to run Synapse as non-root without using a storage class that supports setting rights based on fsGroup

and then

Just pushed the 1.19.1 tags for my K8s-optimized container image, and a new helm chart version to go with it.

Did you know that Ananace is running a Matrix server for LinkΓΆpings universitet?
Another True Fact: "universitet" appears to be Swedish for "university".

Dept of Bridges πŸŒ‰


dalcde offered:

I recently published a new matrix <-> mattermost bridge - matrix-appservice-mattermost. The new bridge already supports many features and is rapidly improving, with the current focus being setting up proper integration tests.

New bridge! This is actually really fully featured considering that we've only just heard about it! Looking forward to seeing more from dalcde and team in future.

Dept of Clients πŸ“±


MTRNord offered:

Some small updates on Daydream:

  • The pages and get finally updated again. We switched from netlify to github pages

  • Devin R fixed a bug with huge numbers in power levels which caused Florian to not being able to join (Fixed in the rust-sdk)

  • Because of the now again working deployment of Daydream parts of the WIP redesign are now available on

  • Github Emoji codes like :gift: Get replaced with unicode on sending allowing basic emoji usage

Also the landing page at got a fresh new design :)

And we are investigating a switch to the Druid framework to also add support for desktop

Check it out at: or join our Chat at

Honestly I didn't realise Florian was a setting in the power levels. Is this in the spec? Very good seeing Rust SDK getting such usage, we will see more from this project I hope!


KB1RD offered:

A multi-account Matrix client that allows you to authorize webapps to access parts of your account, designed with collaboration in mind.

This is the webapp I've been talking about for a while that allows webpages limited access to your account. Currently, apps can view the name, avatar, alias, and type of a room that's been opened with the app, and that's just about it.

The big interesting thing about mxapps right now is the architecture. Just about all of the logic is running in a shared worker. This means that you can duplicate as many tabs as you want and it will all act as the same client. It also has multi-account support.

Features coming ~soon~ at some point will be full state event support and easy-to-follow docs on how to make an app, plus Vue plugins to make development really easy.

You can checkout the live version on, but it is a bit useless...

There are some work-in-progress docs on the structure on

I'll post an example app in a bit ;)

What a great use of workers! The possibilities for this are really impressive...


miruka reported:

Small 0.6.2 release this week, mostly bug fixes:


  • When replying to a message, you can now press enter without entering any

    text to send it directly (useful to "forward" a message).

  • Sending a file while replying to a message will create a pseudo-reply,

    consisting of an "In reply to" text message with no body, followed by the actual file event.

    This is a workaround to the reply restrictions imposed by the Matrix spec.

  • Composer aliases cannot contain whitespace anymore.

    This includes spaces, hard tabs or newline characters. If an alias from your config still has whitespace, only the first word

    will be taken into account (ignoring any leading or trailing space).

  • Faster server browser loading, now gathers all needed data with a

    single request instead of one for each server

  • Auto-focus the "Join" button on invited room pages

    ((Shift+)Tab can be used to navigate between buttons)

  • Auto-focus the "Forget" button on left room pages

  • Themes: modify chat.message.styleSheet to add some spacing between HTML

    list items, see 48663ae


  • Fix @username autocompletion closing if there's more than one character

    after the @

  • Consider the partial text from IME (input method editors) and touch screen

    autocompleting keyboards and for username autocompletion

  • Reset IME state upon autocompleting a username

  • Fix clicking on autocompletion list user not making the username a mention

  • Fix UI freezing when mentioning user lacking a display name

  • Fix mentioning users with blank display name (e.g. only spaces), mention

    them by their user ID

  • Fix text fields/areas unable to be focused on touch screen

  • Fix random chance of profile retrieval requests failing if one of the logged

    in account doesn't federate with other servers (e.g. localhost synapse)

  • Fix composer text saved to disk for the wrong account if that text begins

    by an account alias

  • Servers can potentially return an outdated member list for rooms on initial

    sync, which is one of the possible cause of "Members not synced" error for encrypted rooms.

    When loading the full room list, discard members from the initial sync list that are absent from the full list.

    For those not using the AppImage or Flatpak, this fix requires matrix-nio 0.15.1 or later to take effect.

  • When erasing an account alias inside the composer, send a

    "x isn't typing anymore" notification corresponding to that account

  • Fix potential 403 error on chat pages for invited rooms.

  • Start loading room history immediately when the room join state changes,

    e.g. when clicked "Join" for an invited room page.


Bruno announced:

Released 0.0.34 this week with some fixes to the room list sorting and fixing several crashes. If you clear your session, it will also sort low priority rooms at the bottom of the room list, even if unread, making it a bit more usable until we add more UX refinements to the room list.

Most of the effort this week however has gone into working on end-to-end encryption, having investigated using the rust-sdk for a couple of days, and now looking into a custom implementation based on libolm. This is well on its way with key upload working and device tracking nearing completion.

Getting e2ee will make this a very compelling client! Remember to watch Matrix Live with Bruno above. If you've watched it, remember we have 100s of episodes of Matrix Live to catch up on!


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

Nico ( told us:

I just merged the new event store a few days ago. This means Nheko now doesn't keep messages in RAM! Everything is stored on disk and mapped into memory from disk. This may reduce memory usage a tiny bit, but may increase latency while scrolling a bit. Try it out and give your feedback!

For the developers reading this, I collected some ramblings on my blog here: . Yes, I designed that site when I was like 15, I know the dark theme is a bit too much... Just use Firefox and the alternate stylesheet for light mode! Anyway, I'm very interested to hear how other clients implement their event stores!

Element-Android v1.0.5

benoit said:

Element-Android v1.0.5 has been released to the PlayStore. We are now working to improve user experience with 1-1 calls. We will add support to add and remove emails to your Matrix account, and we are still fixing bugs...

We are always fixing bugs!


Manu has been working hard on iOS:

This week, we made 2 release candidates available through TestFlight. New features are :

  • app access protection with PIN code, TouchID or FaceID
  • the come back of the incoming native call screen

A huge thanks to the community for the feedbacks. It helped us to discover issues like a crash in background due to PushKit. The coming TF (1.0.7) should fix all of them

Dept of SDKs and Frameworks 🧰


nikofil reported:

A PR has been created for cross-signing and SSSS support! It also supports accepting in-room verification requests and will soon also support creating them, after which it should be ready for reviewing. Afterwards, with some minor changes to clients using the library, cross-signing should be available.

Cross-signing in gomuks and more?

Dept of Bots πŸ€–


chloe reported:


A Matrix bot using the library matrix-nio and Docker (specifically aiodocker) for running sandboxed code, allowing users to write their own factoid commands which can perform any task required. The bot launches a new instance of itself every time it is invited to a room, where it can then be configured for that channel by a management website. There is also a web IDE for the factoids, so you can edit and test the bot's output.

  1. Bash-like factoid and command input/output redirection

  2. Run untrusted code for PHP, Python, JavaScript and Java in Docker containers

  3. Manage the instance of the bot from a management server (realtime log output over websockets, schedule commands to run, manage trusted devices and more)

  4. Web interface for factoid editing (create, save, edit and test with live output). IDE from ace from cloud9



Cool! There are so many bot creation systems for Matrix now!

Final Thoughts πŸ’­

Christian offered:

There is one month left until HacktoberfestπŸŽƒ! Prepare your repos now!

It's a great time to get friends and newcomers involved with open source and your projects. During October, merged PRs to any(!) public GitHub repo will count towards a person's score. With four PRs, they get a very neat looking t-shirt from the organizer DigitalOcean. They can also ask for a tree to be planted instead.

As a maintainer,

  1. Add a "Hacktoberfest" label (color suggestion: #FF7518) on issues to point people to tasks with a clear scope.
  2. Let people know that you're interested in contributions and will review them.
  3. Add the label "invalid" on a PR that's spam or a minor contribution that shouldn't count (fixing typos, blindly upgrading dependencies, etc.).

Matrix benefits from Hacktoberfest, but do keep in mind that this is a commercial project from DigitalOcean.

Dept of Ping πŸ“

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

Chethan offered:

  • Room Verification works in Nheko! Still needs some Improvement,working on it.

  • Improving and fixing some caching issues.

  • Fixing some breaking stuff with the new event store Nico is working on.

Dept of Servers 🏒

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander told us:

This week we have largely been working on bug fixes and performance issues.

Changes this week include:

  • The room server now handles input events for multiple rooms in parallel when running with PostgreSQL, which helps a lot with perceived latency

  • Device key queries now obey federation backoffs, so that we don't spend a lot of time making unnecessary requests

  • The key server now only emits changes for /users/devices which reduces database hits significantly

  • The client API now tries to guarantee message ordering on a per-user basis (thanks Anand!)

  • Federated invites are now more reliable and are performed synchronously

  • Invite room metadata is now sent correctly in all cases

  • Accepting and rejecting invites is also now much more reliable

  • A bug has been fixed that caused excessive memory usage in the sync API (bringing the memory usage of my own instance down to less than 100mb)

  • A massive amount of work has been done to reduce database locks in SQLite mode across the entire codebase

  • Some unnecessary code has been removed from the roomserver updaters

Spec compliance has improved slightly:

  • Client-Server APIs: 54%, same as last week

  • Server-Server APIs: 71%, up from 70% last week

As always, feel free to join us in for the latest!


Conduit is a Matrix homeserver written in Rust

timo told us:

While work on federation is going on in the background, here are some other things we worked on this week

Also check out the Romeo and Juliet Benchmark!

Thanks to everyone who supports me on Liberapay or Bitcoin!


Neil said:

This week we added some more federation readers to which should noticeably improve federation lag.


Patrick has continued on with the async/await-a-thon and we are starting to enter the home stretch. Of the things we care about only runInteraction remains. Once done we can get on with profiling the main process.


On the sharding side the last big milestone is to get the event persister to shard. I know this comes up every week, but we now have a rough working implementation for non-backfilled events. Next steps are to get backfill working, get the tests passing, go through review and then ship. I asked Erik if it would be live on within 2 weeks. He didn’t say, at least I didn’t hear him say no…> Aside from that Rich is working on the push rules redesign, the next steps are to design the APIs in more detail and then make a formal spec proposal. Brendan is also in notifications land and his work on room unread counts is going through final review.

Finally, Andrew has been working with Sorunome to dust off the knock feature, both on the spec and the Synapse side.

Romeo and Juliet benchmark to compare Matrix server implementations

timo offered:

This week I created the first(?) Matrix server benchmark and ran it on Synapse, Dendrite and Conduit. The test will go through the entire Romeo and Juliet play and create users for each character and sends messages for each line they say.

The results are very interesting:


     timo         neilalexander    Half-Shot

# default (sqlite)
time 5m0.870s

# postgres:
time 1m46.319s                     1m8s


# default (sqlite)
time 6m8.802s     0m38.502s

# postgres:
time 2m45.387s    0m53.691s


# default (sled)
time 0m4.184s     0m2.776s         0m2.935s


There is some question here about how federation and state resolution will affect performance on these tests.

Synapse Deployment πŸ“₯️

There is rather a lot in this section this week (see also Ops πŸ›  section below.) I'll consider making this a more structured (table?) feature in future.

SELinux policy module

0xC0ncord reported:

Hello! Just recently I made public an SELinux policy module I developed for Synapse. This policy is one I developed early on during my trip down the SELinux rabbit hole, and I have been using it in production for some time. At the moment, this policy module is built for the Gentoo SELinux policy (not RHEL/CentOS/Fedora) and does not currently have systemd support, nor has it been tested in all environments, i.e. with workers. I am publishing this policy in the hopes that it will be useful and I am open to any contributions, even those to help tighten the policy if possible. Finally, I have also made public a policy module for coturn, which I am also using in my own personal environment under the same conditions. Both the Synapse policy and the coturn policy can be found on Github. Thank you!


JCG said:

The ansible collection famedly.matrix has seen another release, 0.1.2, which updates the element role to 1.7.4 and the synapse role to 1.19.0. As always, get it from Ansible Galaxy, source from Gitlab, and for any questions join


Ananace announced:

Just pushed the 1.19 tags for the K8s-optimized Synapse image, as well as an updated chart version for it that also takes advantage of the added /health endpoint.

Void Linux

JCG announced:

Element 1.7.4 and Synapse 1.19.0 have been packaged for Void Linux, packages are already available from mirrors.

dacruz21/matrix-chart Kubernetes Helm Chart

Typo Kign told us:

v2.5.0 of dacruz21/matrix-chart has been released with Synapse 1.19 support and some new configuration options.

Telegram public channel mirror

bo41 reported:

As channels are really popular in Telegram, I wrote a quick and dirty program/bot which can mirror (text and image) public Telegram channels to Matrix rooms. This should make it easier for Telegram users to consider a switch.

Making the rooms read-only via permissions prevents messages from users. It provides a good basis for someone trying to make a real 1to1 mirror. Please fork this project and host some channels publicly ;)

This project is functionally quite different from the more established mautrix-telegram: it is purely designed to mirror content from Telegram public rooms.

matrix-appservice-irc release 0.20.1

Half-Shot said:

Hello all, I'm going to be quick off the mark and announce matrix-appservice-irc release 0.20.1! This release contains a ton of bug fixes and quality of life changes that you never knew you were missing. Please update and report back in the usual channels as always. Thanks!

Nico ( reported:

I've been working on trying to finish the event store (when I wasn't distracted by video calls with some people). This should allow limited offline use and reduce memory use as well as allow some other features in the future. If you want to try it out, you can build this PR or try out the nightlies with new-event-store in their name.

If you decide to try it out, backup your cache or at least BACKUP YOUR ENCRYPTION KEYS! I won't be responding to feedback immediately, since I am currently hiking, but I should get to it this weekend or next week. Come discuss it in, if you have some feedback or issues.

See also Matrix Live this week!

Element Android

benoit announced:

We are still fixing issues on Element Android. Hopefully we will release version 1.0.5 of the application and of the Matrix SDK in the coming days!

later, fidèle à sa parole:

Element Android 1.0.5 has been published on the beta channel of the PlayStore. If everything is fine it will be pushed to production next week. I've also published SDK v1.0.5, and push translations of the PlayStore home page of Element to German, Chinese, English US, Hungarian, Portuguese (Brazil), Russian, Slovak, Swedish and Ukrainian.


steve offered:

This week, we improved customisation for forks. We add possibility to customize default HTTP headers (like "User-Agent") and improve login and room settings screens customisation. We started to improve project documentation. We also made some fixes like fixing registration validation link in email.

Element Web

Ryan announced:

  • Released 1.7.4

    • Updated various links and strings for the new brand

    • Renewed Windows code signing cert

    • Removed rebranding toast

    • All cross-signing keys now shared with other devices during verification

  • This week

    • Mode to require secure backup during registration

    • Continue work on deferred cross-signing setup

    • Light weight Hydrogen client continues, adding key features and design tweaks

    • Notifications continues in background while push rules evolve

    • link previews in progress


Hydrogen is a web-based client designed to be very lightweight, and with few dependencies. Anyone who wants to discuss Hydrogen can join

Bruno told us:

Added several features this week:

  • avatars and display names in the timeline and for rooms

  • implemented the logic for the member list, but no UI for this yet

  • room list sorting by last message timestamp, unread state and badge count

  • clear unread state when reading a room

  • some visual tweaks in the timeline and room list

  • bug fixes

If you have checked out hydrogen before, you'll need to clear your session (the little clear button in the session picker) to get correct avatars and display names everywhere.

Next week I'll get started on E2EE, which should make the project a lot more useful. I'll look into leveraging the nice rust matrix-crypto-sdk for this.


Mirage 0.6.1

miruka hit us with a late breaking update about Mirage!

Mirage 0.6.1 was released today:


  • SSO authentication support

  • Homeserver browser:

    • To add a new account, you will be asked first to pick one of the listed public server (list data from or to manually enter a server address
  • Typing in the server address field will also filter the public server list, Up/Down or (Shift+)Tab and Enter can be used to navigate it by keyboard

  • If the address doesn't have a scheme://, auto-detect whether the server supports HTTPS or only HTTP

  • Use the .well-known API if possible to resolve domains to the actual homeserver's URL, e.g. resolves to

  • The server address field will remember the last homeserver that was connected to

  • Room members autocompletion:

    • Type @ followed by one or more characters in the composer, or one or more characters and hit (Shift+)Tab to trigger username/user ID autocompletion

    • Only autocompleted names will be turned into mentions, unlike before where any word in a sent message that happened to be someone's name would mention them

  • Full image viewer for matrix image messages and URL previews:

    • Click on a thumbnail in the timeline to open the image viewer

    • Middle click on a thumbnail (or use the option in the context menu) to open the image externally

    • Left click on the image (mouse only): expand to window size if the image's origin size is smaller than the window, else expand to original size

    • Tap on the image (touch screen/pen only): reveal the info and button bars when auto-hidden (bars will auto-hide only when they overlap with a big enough displayed image)

    • Any mouse movement: reveal auto-hidden bars

    • Double click on the image: toggle full screen

    • Middle click anywhere: open externally

    • Right click anywhere: close the viewer, back to chat

    • Drag when displayed image is bigger than window to pan

    • Wheel to pan up/down, hold shift or alt to pan left/right

    • Ctrl+wheel to control zoom

    • Buttons to control rotation, scale mode, full screen, GIF play/pause and GIF speed

    • New keyboard shortcuts are available for all these actions, see keys.imageViewer in the config file (will be automatically updated when you start Mirage 0.6.1)

  • Add media.openExternallyOnClick setting to swap the new click and middle click on thumbnails behavior

  • Room and member filter fields now support (Shift+)Tab navigation, in addition to Up/Down

  • Add a colored left border to the currently highlighted item in list views (e.g. room list, members list, etc) to improve visibility

  • Themes:

    • Add controls.listView.highlightBorder and controls.listView.highlightBorderThickness properties (can be set to 0)
    • Add the chat.userAutoCompletion section


  • Messages context menu:

    • Use a cleaner icon for the "Copy text" entry

    • Replace the confusing broken "Copy media address" entry with:

      • Copy media address: visible for non-encrypted media, always copies the HTTP URL

      • Copy local path: always visible for already downloaded media, even if they were downloaded before mirage was started

  • The openMessagesLinks keybind (default Ctrl+O) is renamed to openMessagesLinksOrFiles and can now also open media message files

  • Using the openMessagesLinksOrFiles keybind on a reply will now ignore the links contained in the "In reply to XYZ" header

  • Pressing Ctrl+C to copy selected/highlighted non-encrypted media messages will copy their HTTP URL instead of the filename

  • Retry downloading image thumbnails if they fail with a 404 or 500+ server error (uploads sometimes take a few seconds to become available on the server)

  • Non-encrypted media messages are now always downloaded on click and opened with a desktop application (or the image viewer), instead of being opened in a browser

  • Compress thumbnails and clipboard images in a separate process, to avoid blocking every other backend operation while the compression is running

  • Reduce the level of optimization applied to clipboard images, the previous setting was too slow for large PNG (10MB+)

  • Increase applied scrolling velocity when using the scrollPageUp/scrollPageDown keybinds, now similar to how it was before Mirage 0.6.0

  • Don't catch SIGQUIT (Ctrl+\ in terminal) and SIGTERM signals, exit immediately

  • Slightly increase the top/bottom padding to the multi-account bar in the left pane

  • Dependencies: minimum nio version bumped to 0.15.0


  • Themes: remove unused controls.listView.smallPaneHighlight property

And lots of fixes, see full changelog

iinuwa offered:

We wanted to take a little bit of time to show off a state resolution library for Ruma, courtesy of @DevinR528 and @Timo. Ruma has a new crate to make resolving state easier, state-res! The goal of this crate is to be the base for federation, it provides the necessary utilities to resolve state, sort power events (reverse topological ordering), sort events (based on mainline depth), and a lot of event authentication functions. It is still in the early stages of development, but will be hopefully proved out in Conduit.

Other things that happened this week:

  • Added the invite endpoints from the Federation API

  • Started requiring strong types for event-sending endpoints

  • Augmented error types with error-specific fields (see the livestream here)

Speaking of livestreams, @jplatte streams coding sessions from time to time on Twitch. If you're interested in watching some coding streams to get more familiar with the Ruma codebase or learn Rust in general, follow us at [](!

Very impressed that these features are landing in Ruma first, with the intention of getting them into Conduit.


nikofil reported:

  • SSSS and cross-signing are slowly making their way to mautrix-go! A WIP PR exists for both features and is being developed upon. This will allow any clients that use the library to eventually be able to use SSSS and verify the trustworthiness of other devices based on cross-signing.


Ananace announced:

Just pushed version 2.1.1 of the Ruby Matrix SDK, mainly including a couple of fixes for various minor issues.

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

Slavi said:

matrix-docker-ansible-deploy now makes it incredibly easy to use rust-synapse-compress-state to compress the state groups in your Synapse database.

See our Compressing state with rust-synapse-compress-state documentation page to get started.

Dept of Bots πŸ€–


nikofil said:

  • Device verification was merged to neb! It needs human intervention to approve that the SAS match, of course.

  • A new service called "cryptotest" was added that allows other clients to exchange e2e-related events with neb to test their capabilities (such as encryption, room key forwarding, SAS verification)

Final Thoughts πŸ’­

Christian told us:

Residents of Germany can apply for the Prototype Fund until the end of September. They are looking for new open source ideas or features and fund about 20 projects twice a year with 47,500 EUR for six months (starting in April for this round).

Previously funded chat-related projects include Briar and OpenPush. It would be great to see a project building on Matrix.

SAS Emoji Translations

TravisR said:

We've finally opened up to translate the emoji used by clients to ensure that users are securely verifying each other. The idea is that clients should always have a consistent name for these emoji, even if developed by completely different teams. If your client supports encryption verification and has translations, please transition to using matrix-doc for your translations: has some details, and would love to help out.

Dept of Servers 🏒


Neil reported:

We have a new RC out, edited highlights include

  • lots of async/await changes, 27 separate PRs (thanks Patrick)

  • improved logging performance, this is in part to reduce IO but also to reduce the total amount logged. We’d be really interested to get some feedback on if the changes help. You may also want to take a look at our new logging defaults to see if they would help reduce total disk space usage.

  • Further improvements to the Admin API allowing admin to optionally purge rooms on deletion.

Expect 1.19.0 to land early next week.

Aside from that Erik has been continuing with sharding the event persister, this is a big job, so we’re still a little way off having something to ship, but I’ll keep you updated.

Big news this week, after spending a good chunk of time trying to rework notifications to make the UX more intuitive, we have decided that the best (and only) way forward is to completely rethink how the push rules work. Rich is currently redesigning the whole thing, and once done we’ll resume on the client side.

Having spent much of the past 3 months trying to improve the performance of large scale instances we will soon start looking at improving the out of the box experience for smaller installs and are in the early stages of thinking about what that might look like. I’ll update more over time, but the two obvious use cases to target are

  • Federating instance, with 1-5 users, resource constrained.
  • Federating instance with a few hundred users.

Our (relatively small) changes to logging in 1.19.0 are the first signs of this shift. We still need to ship event persistence sharding and also move more functionality from the main process (dependent on async/await), but once done it clears the way for new projects.


anoa brought it to our attention that this graph looks like a "ocean-beach waterline dropoff".


Conduit is a Matrix homeserver written in Rust

timo reported:

This week I worked a bit on federation! Last week we were able to query room directories over federation; This week I looked into what's needed to join one of those rooms:

  • Resolve room aliases over federation

  • Send make_join request when a user tries to join an unknown room

  • Use make_join response to create send_join request (insert origin, origin_server_ts and add hashes and signatures)

After implementing all those things, I could actually see Conduit's join event on Synapse!


Of course a lot more work is needed to make this really work,

like creating the room on the Conduit side and sending and receiving federation transactions, but this is a start.

Other news:

  • Docker support (thanks to @weasy, @valkum and @paul)

  • Room upgrade support (almost done, thanks to @Faelar)

Thanks to everyone who supports me on Liberapay or Bitcoin!

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander told us:

This week we've been closing off some of the remaining tasks for end-to-end encryption and working on tasks from our beta milestone task list.

Changes this week include:

  • New format for the Dendrite configuration file, which is correctly broken up into configuration per-component

  • Support for server ACLs has been added

  • Significant refactoring of the HTTP routing and API setup to improve flexibility and separation of internal and external APIs

  • A number of improvements to device list handling

  • Key updates are now sent when handling device display name changes

  • Deleted devices are now propagated correctly over federation

Spec compliance is improving:

  • Client-Server APIs: 54%, up from 51% last week

  • Server-Server APIs: 70%, up from 54% last week

As always, feel free to join us in for the latest!

I'm enjoying the close rivalry and progress happening in Dendrite and Conduit right now!


Neil Alexander reported:

Sytest has now been updated to allow skipping tests for endpoints that have been deprecated in the spec. This may be useful if you are writing a homeserver and have no plans to implement deprecated endpoints, e.g. /initialSync or /events.

Use the command line parameter --exclude-deprecated when starting Sytest to skip these tests!

Synapse Deployment πŸ“₯️


Pierre reported:

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

Element Web integration had been updated to 1.7.3


Ananace reported:

Just pushed some WIP (v0.1) charts for both Synapse and the matrix-media-repo project, written with Redis, workers/sharding, PVC constraints, and other large deployment thoughts in mind.

Note that these charts - the Synapse one in particular - basically require you to have a fully featured cluster, with a regex-capable ingress, automated cert manager, and RBAC. They do not require you to have a ReadWriteMany capable storage class though, even when using workers.

and then:

To expand on my earlier TWIM, the charts for Synapse, media-repo, and now element-web are all being used in production now so they are also respectively receiving their 1.0's

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 ( said:

So, we've been silent for a bit, but that doesn't mean we haven't been busy, so I have a little bit of a bigger announcement to make today:

Trilene implemented voice call support in Nheko! We just merged this and you can try it out now!

Some caveats apply at the moment, but will be resolved in the near future:

  • Currently you will need to have a patched version of GStreamer. The current releases of GStreamer have a bug when your turnserver uses a password, that contains a ':'. Since this is the default for coturn, I'm guessing this affects everyone.

  • You will need to build Nheko yourself. Currently we do not have GStreamer available in our CI pipeline, so we disabled support for voice calls in those builds (apart from the flatpak build, but that also needs some further validation and a new GStreamer release). We will release proper builds with VOIP support once GStreamer is actually released and available with the fixes we need.

  • There are still some other issues, when relying on a turnserver to connect a call. We will fix them one at a time.

Big shoutout to trilene for implementing all of this! I can finally call people from Nheko, which is super awesome!

This was the first of the bigger features, that have been cooking for a while, in the near future we should also finish the new event store, which reduced memory usage and provides some kind of offline support, and Chethan will probably finish the first iteration of cross-signing soon too. After that we'll focus on the smaller features again. ;-)

BIG update! Looking forward to trying out voice calls. ☎️ Maybe we'll be calling Nico for Matrix Live soon..?


benoit said:

We are still fixing issues following the Element release. We are also working to add Jitsi conference call support.

We have exported a first beta version of the SDK from Element Android. It is available here: and can be integrated in any Android app as a regular gradle dependency. We will update the SDK after each release of Element Android.

SchildiChat for Android

SpiritCroc said:

SchildiChat version 1.0.4-sc.12 should be up in the Play Store soon.

It includes following changes since the last TWIM:

  • The single-list overview screen is now optional. If you prefer the tabbed layout for separating direct messages and rooms, as known from Element for Android, but still want SchildiChat's message bubbles, you can get that combination now too!

  • Push notifications have been enabled for the Play Store variant

  • Some theme fixes for old Android versions


Bruno told us:

Some regular readers might remember, in the past I've put a few entries here about a side-project called Brawl. Two weeks ago, we took Brawl and started building a new client on top of it code-named Hydrogen.

As the name implies, Hydrogen tries to be the lightest Element. It is written entirely in vanilla javascript (no React, no Webpack) for complete control, structured as an MVVM app, leveraging the raw performance of indexeddb. On huge accounts where Element-web uses up to 1GB of heap memory, Hydrogen sips away with a mere 15mb. It is very early days though, and Hydrogen has very little features: you can receive and send unencrypted messages and that's it.

Hydrogen also aims to support a wider range of browsers, from IE11 (particularly for orgs with locked-down machines) all the way to a fully featured PWA that works well on mobile. We should also be able to easily add progressive loading, which proved hard in the past.

Another goal is to make it easy to embed parts of the app (like the room view) into another app or website. It could also be really nice to have a place to play and experiment with new tech for element proper - much as Dendrite has influenced Synapse.

As mentioned, it's early days, and lots of things are missing or broken, so please don't file any issues yet. Feel free to play around with it at though!

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

iinuwa announced:

Lots of exciting things happened in Ruma this week:

  • We have officially implemented over half (18/31) of the Federation API endpoints!

Special thanks to @agraven and @q-b!

  • We've added the only new endpoint from r0.6.1 of the C2S spec.

  • We have begun work on adding support for borrowed types for requests. This should reduce the memory allocations required for clients to send requests to

a server.

  • Exported some macros to make creating custom endpoints and events that

much easier.

Support for Ansible collections from Famedly

JCG told us:

There's news from ansible land! Ansible recently introduced a new packaging format, the "collection", and we've now started moving our ansible content into collections. This means the matrix modules I twim'ed a few months back are now easier to install than ever before, and the synapse/element roles are included in there as well (thanks to madonius for the contributions there). The roles have been regularly updated for a while now, and the element role isn't even called riot anymore! You can get the collection on Ansible Galaxy, with the source being available over on GitLab. In case of any questions, feel free to hop over into

terry_hello said:

Hi All,

I’ve created a compact and portable home server based on Matrix protocol, it’s a piece of hardware which is easy to use and set up. I’m working on a new client APP similar to other typical messenger GUI, but this server we named it β€˜Privee’ supports any messenger developed with Matrix protocol. I’ve launched a campaign on Kickstarter this week, please come and support us! Thank you!

Privee is an interesting project alright! The project creators are based in Hong Kong, and are working from a desire to have more control over their communications. The plan is to run homeservers on a small computer physically located with the user, similar to plans outlined by NovaChat.

This is an early-stage project (hence starting on KickStarter.) While exciting and ambitious, I encourage everyone to do their own research! Learn more and chat with terry_hello (who has done a good job handling questions already!) in

iOS P2P Demo

Dendrite is a next-generation homeserver written in Go

Neil Alexander said:

The Element P2P demo on iOS has seen a number of updates in the last week - now at build 31 - which contains a number of fixes:

  • QUIC session setup is now far more reliable

  • QUIC sessions are now reset when the node's network coordinates change

  • The federation sender now wakes up properly on incoming QUIC sessions

  • Network coordinates are now cached for remote federated nodes, reducing the number of DHT searches and speeding up resuming federation

  • HTTP pools are disabled, which reduces head-of-line blocking problems on stalled sessions

  • A number of timeouts have been lowered

  • Dendrite has been updated to the latest version

matrix-media-repo v1.2.0

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

TravisR told us:

v1.2.0 is out now, with a bunch of bug fixes and some added features:

  • Thumbnail support for apng and webp images (thanks Sorunome!)

  • Experimental (but pretty stable) support for Redis as a cache - instructions here

  • Optional oEmbed support for things like previewing tweets - turn it on here

  • Dynamic thumbnail support

  • Per-user quotas

v1.2.0 is also much faster at file uploads, however some areas of matrix-media-repo can still be improved - general performance work is planned for the next release.

Learn more about matrix-media-repo.

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander announced:

We are happy to announce the beta milestone for our first versioned release of Dendrite, which we anticipate to land in the next few weeks. Once these issues are cleared, we'll have made the big breaking changes that we want to make and will have a migration mechanism in place for database schema upgrades.

This will make life significantly easier for anyone who wants to start experimenting with and running their own Dendrite homeservers without unexpected breakages. More updates to follow soon - join us in for the latest!

This week, Dendrite's end-to-end encryption support has also been mostly rounded off with the exception of a few minor bugs and edge-cases.

Changes this week include:

  • TLS certificate verification is now enabled by default

  • A new federation_disable_tls_validation config option has been added to override the above

  • Added support for processing inbound device lists from federation

  • Local device list changes are now sent outbound over federation

  • One-time key counts are now sent in /sync

  • Direct server signing key fetches are now limited to 15 seconds

  • State events that fail signature checks on federated room joins are now properly ignored

  • A number of SQLite database lock bugs have been fixed using TransactionWriter

  • A bug when finding joined hosts in the federation sender in SQLite mode has been fixed

  • Logging levels have been adjusted in a number of areas

Spec compliance:

  • Client-Server APIs: 51%, same as last week

  • Server-Server APIs: 54%, up from 53% last week

Asked whether this progress means that would be running on Dendrite next year, Neil said he was certain that it would definitely be ready:

Anything is possible

  • Documentation and code cleanup

  • Getting initial server_server code back into shape

Thanks to everyone who supports me on Liberapay or Bitcoin!

Oh and btw look at Matrix Live this week!


Patrick offered:

This week in Synapse land we continued with our performance push making further progress on the async/await-athon. We will move into the storage layer this coming week which will leave the caching layer and a few other bits outstanding. Separate work continued to get the event persister into a shardable state. The first step being to replace the event stream token with its own type and then threading that through the code base.

We have also continued to improve on our push capabilities and released a new version of Sygnal (0.8.2) with support for pushing to iOS devices via Firebase.

We are also very close to getting a workable version of the new push rules. The idea is to test it out in the wild before getting it enshrined in the spec.

Next week will see a continued focus on sharding and async/awaiting, more notifications work, logging improvements, and a host of bug fixes!

maubot rss plugin

Tulir reported:

I released v0.2.0 of the maubot RSS plugin. The most recent addition is support for JSON feeds, stolen from inspired by FantasyCookie17's jsonfeed-bot.

Other changes since v0.1.0:

  • Per-feed toggle to send posts as m.text instead of m.notice
  • Automatically moving subscriptions across room upgrades
  • Some fixes for handling weird feeds

maubot/rss is a maubot plugin that posts feed updates to Matrix rooms. It supports RSS/Atom/JSON feeds, customizing message templates per-feed/room, and more.

mautrix bridges

Tulir reported:

All my bridges now have options for automatic e2ee key sharing in portal rooms. Currently they don't have verification support (other than manually marking as verified in the database), so enabling key sharing isn't entirely secure yet. I'll probably invent some sort of web verification interface after nikofil adds cross-signing to mautrix-go.

This also means mautrix-python now supports sending and responding to key requests. I'll port the interactive verification and future cross-signing code from mautrix-go to mautrix-python at some point too.

Dept of Clients πŸ“±


Alexandre Franke offered:

4.4.0 is out as promised last week! Get it off Flathub now.

After we announced our intention to release, we discovered a regression that prevented joining new rooms because there was a mixup between room aliases and room id during a switch from internal structures to ruma-identifiers. Luckily we managed to fix it in time and make the release as intended.

Full changelog since 4.2.2

New features

  • Videos now have a preview directly in history

  • New videos player: click on a preview to open it

  • Improved audio file support, with a nicer presentation and seeking

  • Redacted messages are removed from history

  • Edited messages are replaced with their new content and show a small icon

  • Translations have been updated

  • Spellcheck language is saved per room

  • New swipe-back gesture to go back from room to room list in narrow view

  • New swipe left and right gesture to navigate through media in media view

  • SOCKS proxy are now also supported


  • Thumbnail for pasted images have been fixed

  • File type detection for uploads is more reliable

  • Typing notifications are now only sent when text is actually typed in the message input

Under the hood

  • Code refactor is still going

  • Some improvements to logging, including access token removal for privacy

Element Android

valere told us:

Sorry we missed last week TWIM!

  • Element Android 1.0.4 πŸš€ has been released to the store, it contains several bug fixes, and is adding back some moderators functionality (see list of banned users for a room + actions)

The team has been mainly working on stabilisation + refactoring of the current code base.

We are also trying to give more visibility on what is coming next:

  • Pin code protection πŸ”“ (merged on develop)

  • Improvement of big media upload

  • Cancelling send, retries, better upload progress...

  • Call fixes and improvement

  • Improve fdroid polling for notification

The team is partially off, expect some delays in handling of issues and PR reviews

SchildiChat Android

SpiritCroc reported:

SchildiChat is a new fork of Element for Android (previously RiotX), which features some UI changes, to make it more comfortable to use for people who are used to other common instant messengers.

The most important changes are the following:

  • The overview screen lists all chats in one list instead of the tabbed layout in Element

  • Message bubbles (optional)

  • Theme choice based on the system-wide dark/light theme on recent Android versions

It is now available on Google Play, it might appear on F-Droid too in the future. is the place to find out more.

Hello, World! [IndieChat], a new Android matrix client is in Play Store:

This is forked from FluffyChat:

I have changed the archive feature. Added a splash screen. Further simplified settings. Login times work faster compared to FC. I am connecting it to my Jitsi instance. which operates p2p and is completely analytics free. Message notifications are analytics free. It will eventually be an extension to a videocall app developed by myself. It adds variety to the ecosystem. It strictly follows license rules, credits the developers and links to their wonderful work. And it is a great thing to do in my spare time ☺️

simple matrix bots with matrix-nio

Hey all! I built yet another bot library. matrixbz was built with the intention of making it easy to draft matrix bots. Check out the github - I've added some examples where you can build a bot in ~10 lines of python code. matrixbz features:

  • Auth - you can specify user(s) who are authorized to call commands. bot only accepts invites from those users.

  • Cache - you can cache results for particular command invocations.

Check out the package.


iinuwa reported:

We have released version 0.0.1 of the ruma crate! Thanks to all of our contributors!

Besides that and continuing to refine ruma-events, here are some other highlights over the past couple weeks:

  • Implemented a few more endpoints implemented on ruma-federation-api

  • Added helper macros for creating identifier types

Cos told us:

Hemppa the bot is a general use bot that has lot of modules for various uses and super easy API to create more. Hemppa received support for Mastodon. Now you can login to your Mastodon account and send toots via Matrix. Next major feature would be to subscribe to hashtags and users and get notifications to Matrix rooms.

HOPEless, the HOPE conference bot

valka said:

The Hackers on Planet Earth conference went almost entirely self-hosted this year due to not being able to hold an in-person event, and used Matrix to go virtual! hopeless was the robot-heart of the conference, providing community+room ACLs for attendees. The bot also has a bunch of other features including:

  • configured admins sending notices to rooms

  • ability to manually and programmatically schedule announcements for scheduled events happening, like workshops or talks

  • the ability for users to re-join rooms and generate invites for themselves as necessary

  • admin commands for inviting attendees and presenters without tickets

  • an attempt to be friendly and solve people's common problems without a real person having to assist (surprisingly effective!)

Many thanks to the nio-template for existing, otherwise this wouldn't have been possible!

anoa (nio-template) creator responded:

Wonderful! I plan to give it some more love soon, including some docker magic to make it easier to run.

Dept of GSoC πŸŽ“οΈ


karlik announced:

for matrix-ircd

  • Merged update for total move to async / await into development branch, (hopefully) soon to be merged to master

  • Made single-threaded project thread-safe for easily scaling up to potentially many threads

  • Added additional logging for tls and non-tls connections for more clear debugging

Dept of Servers 🏒

E2E Dendrite

Dendrite is a next-generation homeserver written in Go

kegan reported:

E2E Dendrite work is progressing, and we're making a lot of breaking changes ahead of our first stable release which you can expect in the coming weeks.

As for the changes this week:

  • Add a bare bones user directory. This is mainly to benefit the iOS Yggdrasil demo.

  • The dendrite-config.yaml configuration format has been overhauled. It's still in review but expect big changes here!

  • Fixed a bug with SQLite when handling large rooms (thanks @HenrikSolver!)

  • Device lists now work locally, with federation support to come.

Spec compliance is up from last week:

  • Client-Server APIs: 51%, up from 49%.
  • Federation APIs: remains at 53%.


Conduit is a Matrix homeserver written in Rust

timo announced:

Welcome back! This week was very productive:

  • Ignore users (thanks @devinr528)

  • Long polling (faster and more efficient /sync)

  • Fix and improve presence

  • Room tagging (thanks @gnieto)

  • /publicRooms pagination

  • Refactor endpoints into modules

  • Export endpoints as a library (useful for p2p!)

  • Config options to set the maximum upload size or disable encryption

  • and more!

Thanks to everyone who supports me on Liberapay or Bitcoin!


Neil offered:

This week we shipped 1.18.0 which contained support for our worker sharding performance projects that you’ve been hearing about recently.

We also shipped a security and feature release of Sygnal (actually two each…). The main new feature being the ability to run behind an HTTP proxy which is useful in environments that mandate that all traffic go through a proxy.

Aside from that week we continued our async/await-athon and Patrick provided a visual update


We’ve been documenting worker support and diving into sharding the event persisters. This is not a small job since it means every other part of the code base that assumes an integer stream id will need to be updated to be aware of multiple stream ids from multiple persisters.

Over in feature land we’ve been working on the notifications project and most of the backend support is done. The project will mean more intuitive defaults as well as a much better client UX in configuring notification settings.

Finally special thanks to Aaron Raimist for a bumper docs PR

Synapse Deployment πŸ“₯️


Ananace offered:

Just pushed the 1.18.0 K8s-optimized Synapse images, now only doing the debian-based version as like upstream - though still including jemalloc. So latest/v1.18.0 and *-debian will be the same in this version and going forwards. Additionally, the *-debian tags will only remain for a release or two more before disappearing, as they're now superfluous.

Dept of Bridges πŸŒ‰


Tulir offered:

I finally added automatic backfilling options to mautrix-telegram. Like my other bridges, it can backfill old messages when creating portals and missed messages when restarting, and it can disable notifications in the room while backfilling.

I also added bridging for your own read receipts, so if you read a message with another Telegram client, the bridge will mark it as read on your Matrix account with double puppeting.

Dept of Clients πŸ“±


eric reported:

NovaChat is a new Matrix-based desktop client that aggregates all your chat networks into one app

July 31 Updates:

  • New room list design, featuring collapsible 'clusters' (see gif)

  • Enabled encrypted room search (thanks!)

  • Added [mautrix-twitter](

  • Worked around FB Messenger bridge 'forced-logout issue' by routing traffic through proxy on Raspberry Pi at each users home

In the works...

  • Create new clusters of chats in room list, using tags

  • iMessage bridge, using jailbroken iDevice

  • Android Messages bridge

Adding new users weekly. Sign up for the NovaChat beta. Or send me a DM



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

Tulir told us:

gomuks can now do interactive verification for e2ee. Most of it is thanks to nikofil's SAS verification PR to mautrix-go, I just made a UI for using it. Currently gomuks can only send verification requests, but I'll add some interface for accepting incoming requests soon.

Related to verification, there are some new commands for verifying/unverifying/blacklisting devices and viewing device lists. There's also a toggle to disable sending messages to unverified devices.

This is super exciting, raises gomuks to the level of a daily driver IMO.


Alexandre Franke announced:

We will release version 4.4 next Friday. Now is a good time to test the nightly version and check if it doesn’t break anything with your homeserver compared to 4.2.
The changelog has been sparsely given in previous TWIMs, but you could have a look at

Element-iOS, previously Riot-iOS

Manu announced:

We released 1.0.2 this week to the AppStore and on TestFlight. It's mainly a bug fix release after the Element rebranding.

Dept of SDKs and Frameworks 🧰


nikofil offered:

SAS verification support has been merged! Support for it should also be landing in go-neb soon, both for verifying with the bot's device and for testing with go-neb's client testing service. Next up, looking at SSSS and eventually cross-verification support.

Dept of Ops πŸ› 


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 1.15.2 (1.17.0 available in branch testing)

Riot Web integration had been updated to 1.6.8 (Element 1.7.1 available in branch element)

Final Thoughts πŸ’­

Tobi said:

We, some German Synapse admins, have created a survey about the usage of Matrix-Synapse for private statistic purpose (results will be published alike). As suggested in, this could also be a topic for "TWIM".

Find the survey at

New guide for client e2ee implementation, including cross-signing

Thanks and congratulations to Sorunome this week for releasing a new guide: Implementing more advanced e2ee features, such as cross-signing. This is a hugely detailed guide detailing the necessary steps to enable Cross-Signing and verification. Thanks as well to uhoreg and poljar for their work in reviewing the text!

New Masters Thesis written on Matrix

Julian Sparber announced:

I wrote a master thesis that tries to create e2e encryption based on Ethereum on top of Matrix. It may not solve all problems but it's an interesting experiment

I didn't get to look at this yet but it's exciting!

Dept of Spec πŸ“œ

kitsune (guess who's back!?) said:

I have put the long-awaited MSC2312 out of WIP - this is about matrix: URIs in case you haven't heard - and it's already in active discussion at! Join the fun to make it the most awesome! The upcoming Quotient 0.6 has an implementation of those so adventurous Quaternion users can start experimenting right away.

New MSCs:

Spec Core Team

In terms of Spec Core Team MSC focus, we've reduced last week's list of 5 MSCs down to one, MSC2674 (aggregations part 1: relationships). Next week, we're going to focus entirely on that MSC to make some headway on finally getting aggregations into the spec.


Dept of GSoC πŸŽ“οΈ

HTML embeddable Matrix client

arnav-t announced:

For the GSoC project HTML embeddable Matrix client this week:

  • Added status bar for connection errors

  • Added support for displaying typing notifications

Dept of P2P πŸ‘₯

P2P / Dendrite

Dendrite is a next-generation homeserver written in Go

kegan announced:

The P2P Yggdrasil iOS demo has seen some improvements:

  • Federation sender blacklists are now persisted which is important as the iOS app will be frequently terminated.

  • SQLite3 now uses TransactionWriters in more places to reduce the amount of 'database is locked' issues.

  • Federation sender has had much of its storage code refactored and de-duplicated.

In addition, there has been much work getting Dendrite to support E2E rooms, which it now mostly does.

You can create and join E2E rooms and have a conversation locally, though there's issues with it over federation. In addition, Dendrite currently lacks device lists so adding new devices may result in unable-to-decrypt errors:

  • Send-to-device events now work over federation.

  • Device key uploads and querying now work both locally and over federation.

  • One-time key uploads and claiming now work both locally and over federation.

Spec compliance is up from last week:

  • Client Server APIs: 49%, up from 48%.
  • Federation APIs: 53%, up from 51%.

Doesn't it feel like we'll be using Dendrite in the wild really soon now?

Dept of Servers 🏒


Conduit is a Matrix homeserver written in Rust

timo offered:

Another quiet week. Next week should be more exciting again.

  • Moved to stable rust (rocket now compiles on stable!)

  • Implement /joined_rooms (thanks @aura)

  • Add max_request_size config option to set the maximum size for file uploads and other requests (thanks @CapsizeGlimmer)


Neil said:

This week we continued on our async/await athon, you can track progress here, expect steady progress over the coming weeks.

We dusted off the notifications project working with our pals in the Element client teams to ensure that the push rule defaults make sense. On the flip side we made further improvements to Sygnal and will merge the ability to have it sit behind a proxy rsn.

We are also trying to figure out how media retention limits should work in Synapse.

Up next is to continue our performance push. We need to spend time between pulling things off the master process as well sharding the event persister. We will continue with notifications and maybe finally squash

Dept of Bridges πŸŒ‰

Introducing matrix-figma

Half-Shot reported:

Hello people. It's been a while since I've talked about a new bridge...or actually any bridges. Fear not, now you can hear both! Today I'm announcing the birth of another project matrix-figma. Figma is an online collaborative design tool. It was created to scratch an itch with the Element design team, who wanted to see comments appear in their Matrix rooms in realtime when someone commented on a Figma file.

The bridge works by first joining it to an "admin room", which functions as a permitted user list. The bot can then be invited to any other room so long as the invitee is in that admin room, and can then ask the bot to start directing comment notifications into the room.

The room uses room state to hold configuration, so you can host the bot as a docker container anywhere without the need for any support files!

I can announce that the bridge is now functional for simple use cases such as these, with more interesting functionality in the future.

Please check out to see if the bridge is right for you :)


Sven offered:

I opened a PR for, which makes it compatible with recent Synapse versions and adds new config options allowing to effectively import a Slack workspace history to an existing homeserver via federation.

This Python project was initially intended for a full migration from Slack to a new Matrix homeserver and allows reusing the imported user accounts. We have some research groups using Slack that would like to import their Slack workspace history to our Matrix homeserver. This PR allows to import a (free) Slack export to a fresh and empty Synapse instance that is federated with our main homeserver. We do not need a full "migration": we kick all imported users and invite the existing Matrix users from our homeserver.

Two groups already imported the history and switched to Matrix, one more is in queue and probably more to come.

This is a really, really exciting development, and the context for which Sven is expecting to use it is BIG, I can't wait til we can share more about it!


Tulir said:

The Twitter DM bridge I announced last week mostly works now. It does text and reaction bridging in both directions, twitter->matrix media bridging, end-to-bridge encryption and backfilling. I also added support for it in mautrix-manager for web-based login.

If it mostly works, I guess it's time to mostly start trying it out!

And more: full changelog

Riot-iOS, no sorry, Element-iOS

Manu offered:

Last week, we forgot to announce that we renamed the Riot-iOS app to Element but this is not a surprise anymore. The app version is now 1.0.0. This change came with a lot of UI tweaks like new icons and new colors.

Since then, we made bug fixes we will release soon. This week, we also worked on PIN protection for the app, including support of Touch ID and Face ID.

Element Android

Francis offered:

This week has been focused on bug fixing, there will be a release next week. We also started to work on PIN protection for the app.


kitsune offered:

Quotient 0.6 released! The release notes are somewhat long, since it's been 4 months since the last stable version update, and more than a year since the 0.5 release - thanking two heroes of this release, and giving a nod to the original Quaternion author who happened to contribute using an inverted time machine. Read here:

Big news - first release in a year. Do take a look at the full notes, they're very readable. In particular, they call out contributions from Black Hat, Alexey Andreyev and the original project creator, Felix Rohrbach aka @fxrh.

jplatte said:

We weren't in TWIM for a while, but that doesn't mean no progress! Apart from Devin's constant work on ruma-events, there was also some movement in ruma-identifiers and ruma-client-api, with the former seeing a new release, 0.17.0.

We're planning to do more releases next week, and hopefully a 0.1 release of the ruma crate that provides a simpler entry point by re-exporting everything else, in one of the weeks after that. Stay tuned!

Dept of Bots πŸ€–


dandellion said:

It's been a while since it's come up, but matrix-wug is a bot capable of transcribing characters writable via normal keyboards to scripts from other languages/notation systems

It supports: x-sampa, z-sampa, proto-indo-european, Inuktitut, and IΓ±upiatun.

Now it also supports hiragana! The romanization system is something like Wāpuro rōmaji, but sticks to Nihon-shiki when in doubt.

I want this transcription to be forgiving, so if you find it not transcribing something in a way you'd expect it to, feel free to DM me!

To use it use the hi key with a delimiter like /x/ or []

hi/konnichiwa maatorikusu!/

vΓΈgg is also behind pantalaimon now so it now works in encrypted rooms πŸ˜€

If you need to convert swiggles into a different type of swiggle, dandellion has you covered here.

Jitsi Token Service

kinta reported:

This bot is not about adapting the current jitsi integration provided by Element IM as widget.

If you have a configured jitsi server to be authenticated with jwt tokens as in , this bot will assist you when claiming for a jwt instead of going to each time. You'll need to create a user and invite you in each room where you want to create a jitsi room url respecting the matrix power levels in the room.

When the service is running invite the bot and send message !jitsi-jwt

If you are a moderator in the room (alias you have enough power levels to redact messages), then you will get a direct message from bot with the url to jitsi room with the jwt get parameter.

cody 0.7.0

carl told us:

New cody release. is a chat bot that works as a REPL for your matrix rooms. This week I worked on metrics. I host a Grafana instance with anonymous access allowed, so codys charts are now embedded the chat room.

Announcing The Very First Release of sMythbot

ssorbom told us:

I am proud to announce the very first release of sMythbot, the Matrix chatbot designed to control your Myth Tv DVR remotely. This release should be considered a tech preview. I welcome feedback and Bug reports. More information on installation and setup is available in the project wiki.

It currently supports the following commands

  • !smythbot help: Display this message

  • !smythbot set mythbackend address: Sets the Myth Tv backend address to use for this room.

  • !smythbot set mythbacked port: Sets the Myth Tv backend port to use for this room.

  • !smythbot view mythbackend address: Allows you to view the Myth Tv backend address set for this room

  • !smythbot view mythbackend port: Allows you to view the Myth Tv backend port set for this room

  • !smythbot view mythbackend info: Allows you to view various pieces of information for the Myth Tv backend connected to this room. It will not work if the address and port are not set.

  • !smythbot display upcoming recordings: Displays the upcoming recordings on your Myth Tv Backend.

  • !smythbot display recorded programs: Displays the recordings from the default recording group that are stored on your Myth Tv Backend.

You can find out more information at my Github Page

I love a project designed to scratch the author's own itch!

Noteworthy Elements for Mobile Web

balaa said:

The team behind Noteworthy (Matrix over WireGuard overlay networks) has started work on bringing better mobile web support for Element (riot-web).

Noteworthy Elements is a lightweight shim powered by the Ionic Framework thats goal is to bring first-class support for Element running on mobile devices.

What we have so far

  • Usable version of Element wrapped in native iOS / Android app

  • Ability to run multiple instances of Element in a native iOS / Android app (ie connect to multiple home servers simultaneously)

Our initial experimentation has been positive and our goal is to make Element the best mobile client for Matrix with minimal fuss. With minimal changes to Element's codebase our goal is to land (significantly better) support for mobile web in upstream Element. Join us over at to get involved!


Trust-based Moderation Using Distributed Chat Systems for Transitive Trust Propagation

Florian said:

I just stumbled over the master thesis TrustNet: Trust-based Moderation Using Distributed Chat Systems for Transitive Trust Propagation. While it is mainly targeted at systems like Secure Scuttlebut and Cabal, I think it is also of interest for the people thinking about trust-based moderation for Matrix.

Let's hear from Christian about working on his dream projects, his thoughts on bridging, hosting, and the importance and nature of chatbots and assistants.

Dept of Status of Matrix 🌑️


This week was the announcement of the much-awaited rebrand: Riot is now Element. In fact, three brands are coalescing into one: Riot and New Vector will be referred to as Element, while the SaaS platform known as is now Element Matrix Services.

Note that Matrix is not involved in this change. Matrix is still Matrix, don't worry about that!

CommCon Virtual 2020, with added Matrix

CommCon is an event dedicated to Real-Time Communications. In 2020 they made the difficult decision to go online-only, but had a fear of missing out on the "hallway-track" that is so important to industry events. Their solution was to include a live chat to run alongside their streamed talks!

Matrix was a natural choice for the crowd, but they wanted a way to encourage viewers to join the correct room from their own Matrix clients. To do this, they used the GSOC project from arnav-t - an HTML Embedded client - to present a live scrolling-view of the chat. You can see the result at

Ruma/Matrix GSoC update

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

devinr528 reported:

The End is Nigh

This week in the ruma/matrix Google Summer of Code project, I worked on refactoring both ruma-api and ruma-events. After moving some of the larger chunks of the ruma_api_macro::api::Api::to_tokens method to helper functions, I spent time removing repetition from the Request/Response code generated by the ruma_api! macro. For ruma-events, the input parsing was changed to only allow valid names for the Any*Event enums. Altering the input parsing had the added benefit of replacing all of the string comparison and manipulation with strongly typed comparison and manipulation.

The final few issues to be resolved before the next release for ruma-events can happen are related to redacted events. Support for redacted events was added to the Any*Event enums, they now have redacted variants of each event kind. A few follow-up PR's have been merged to fully integrate redacted events into ruma-events, fixing specific event deserialization issues and splitting the UnsignedData struct into Unsigned and RedactedUnsigned.

HTML Embeddable Matrix

arnav-t reported:

This week for the GSoC project of HTML Embeddable Matrix Client:

  • Added a read receipts menu for messages.

  • Minor bug fixes

  • Automatic hyperlinking of URLs in pipeline

Neil said:

A big week for performance.

Hot on the heels of shipping shardable federation readers last week, this week we shipped shardable federation senders. There is still plenty of work to do, but together these changes has made a massive difference to federation lag overall and hopefully those of you not on are noticing the difference when you talk to users.

This graph shows the impact to outbound federation lag.


Aside from that we also shipped shardable push and frontend proxy workers as both were starting to max out on CPU as well as a shardable client reader, allowing us to shard registration which was especially important this week :)

Finally we moved typing notifications from the master process and optimised incoming replication queuing to buy us a little more head room.

Next steps are to revisit where all the remaining cycles are going on the master process. To help us profile we are migrating to async/await semantics and Patrick produced this natty graph to track progress.


Outside of performance we shipped a bug fix to prevent large initial syncs taking out the synchrotrons. The admin api sprouted an end point to list room members (thanks awesome-michaeland the ability to reactivate previously deactivated users.

Coming up we’ll dust off the notifications project which has been put on hold while Riot transmogrified into Element and we’ll continue with chipping away at the master process.

Tulir announced:

I started working on a Twitter DM bridge that uses the internal API instead of the complicated official one. It should be easier to set up than bridges using the official API, since there won't be a need to get API keys and forward webhooks. The main risk is that Twitter doesn't like people using the internal API and starts blocking users like Facebook does, but hopefully that doesn't happen.

So far I've only made a simple library for the API, but the bridge should be usable by the next TWIM. The bridge and API library are at and there's a discussion room at

Element Android 1.0.0

benoit announced:

Element Android 1.0.0 is out! Download or upgrade it from the PlayStore at or download it from the F-Droid store at

  • PlayStore users: Element should come as a regular upgrade of the application Riot-Android, and the upgrade will update your previous account and data, without the need to log in again.

  • F-Droid users: Element is a new app, you have to install it and log in again.

  • RiotX: RiotX will disappear from the PlayStore (it was only a beta application). We will provide a very last update to inform users to install Element Android

Please report any issues at (which will probably be renamed soon), because Element Android is actually RiotX code! Thanks for all the contributors of RiotX, we still have lots to do to make the app even better and full featured.


Davo announced:

After seeing all the Element room avatars, I thought to myself, "you know what, needs a new icon"… so I sat down and combined a couple of icons. The result:

Radical icon

Radical also quickly (as always) got updates when Element 1.7.0 and 1.7.1 were released. Huge thank you to stoic for making Radical in the first place.

Element F-Droid repos

krombel announced:

I updated my F-Droid repos which are containing the dev builds to reflect the latest naming change to Element.

The people who formerly used my repos for getting the dev repo of Riot-Android should update to the new repo. It wont be updated to get Element

As always you can grab the F-Droid or GPlay flavor and you can pick the repo which reflects your flavor on

Note: As "the new repo" is internally the same repo as the one of RiotX (and Riot.imX) the people who already used that don't need to update their packet source. They will get the updates to Element via the old repo urls.

Dept of SDKs and Frameworks 🧰


Tulir announced:

As promised last week, maubot now supports end-to-end encryption. It's a bit bare at the moment, so you need to manually insert the device ID into the database for it to start working, but other than that it works. Plugins don't need to be changed at all, the framework will handle everything.

While I was adding e2ee to maubot, I also improved mautrix-python's crypto stuff so that it's easier to use it directly as a client library with e2ee. Some day I might even add docs :D

Riot iOS P2P Demo

Neil Alexander announced:

Over the last couple of weeks I have been working on the next P2P demo, using Yggdrasil as the transport instead of libp2p. Although libp2p is arguably more featureful in many ways, Yggdrasil does have one major benefit in that it provides full overlay routing. Participants in the network can carry traffic on behalf of other participants, resulting in something much closer to a true mesh network.

The mad science doesn't end there however. I've also built a custom Riot iOS build that includes the full Dendrite P2P demo (yes, that's a homeserver running locally on your phone). If you have an iPhone or iPad, it's available in public TestFlight right now and you can play with it!

The demo still is very experimental and has a number of bugs still (including but not limited to messages occasionally taking a while to deliver, the app crashing when going into the background sometimes etc.) but we'll be improving it further in the coming weeks and it's quite fun to play with, particularly if you can do so with other people nearby.

Thanks to the same technology that powers AirDrop, the demo will automatically find and connect to other nearby devices running the demo and build up a network automatically - even if you are not on the same Wi-Fi network (or indeed connected to Wi-Fi at all)! If you don't have any other nearby peers to test with then fear not - you can still configure a public static peer in the app settings and join the wider network that way.

With any luck the room directory will even work too, showing published rooms from other nearby devices. If not, try joining #beachparty:b5ae50589e50991dd9dd7d59c5c5f7a4521e8da5b603b7f57076272abc58b374 from within the app.

A new way to test homeservers - Complement

kegan reported:

Many of you know that I work on a Go homeserver called Dendrite, and so I've had to get familiar with SyTest: a black-box homeserver integration testing project. Unfortunately SyTest has a number of problems: from the dialect of perl, lack of documentation for federation bits, the inability to run a single test, and so on. Having a solid black-box integration testing project is crucial for the ecosystem to ensure spec compliance (and hence compatibility between server implementations) and for making all servers more stable and reliable.

As a side project I've been working on a modern Go rewrite called Complement which is now ready for a bit more exposure. It currently only has a handful of SyTests converted but I hope to rapidly expand the number in the coming weeks. Complement makes heavy use of Docker to agnostically run homeservers, and already includes a Dockerfile for configuring a Dendrite instance. To try it out, clone the repo and run:

(cd dockerfiles && docker build -t complement-dendrite -f Dendrite.Dockerfile .)

COMPLEMENT_BASE_IMAGE=complement-dendrite:latest go test -v ./tests

If you're interested in learning more and maybe adding some tests check out

My overall hope is that Complement will lower the barrier to entry when adding tests by so much that it encourages any bugfix/feature in any homeserver implementation to result in a new test. This will benefit everyone and create a feedback loop which will make Matrix even more reliable.

Asked about Sytest and SyTS, Kegan added:

Complement currently implements the same tests as sytest, so tests which pass sytest will pass complement (though that will diverge as complement will guard against more race conditions by default). There's about 9 different kinds of tests currently testing CS-API and Federation (outbound to a dummy server and inbound via a federation client)

The problem with SyTS was that the test tooling around it ultimately wasn't expressive enough. I was using Jest and kept finding myself fighting it by bumping up against issues like and the multi-process parallelisation stuff was too opaque. The assertion helper functions also lacked context because they rely on behavioural testing names like describe("foo") { it("should say bar") { ... } etc so when your assertion fails (eg wrong value for a JSON key using assert equals) it just says unhelpfully "foo != bar" where what I really want is to know what it actually does say then, and other contextual info around the object (maybe the key name was typod). When I realised that the assertion lib didn't have this and I'd need to add it, coupled with parallelisation concerns and head-desking against Jest, I found myself wishing I just used something else. I stuck with it though and then realised that all the federation stuff (signature checking, canonical JSON, etc) would need to re-implemented when I knew I had working code in Go. Both of these things combined and I thought "you know what, I'm just going to do this in Go" but you'll note that the architecture is identical, so SyTS lives on as an early prototype for Complement ;)

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander told us:

While I've been busy distracted with the P2P demo, Kegan has been on a mission to implement some new features. Changes this week include:

  • Redaction is now mostly implemented

  • User-interactive authentication is now implemented

  • Device lists in the client API are now implemented

  • Media APIs are now available on both /r0 and /v1 endpoints which makes Riot iOS a bit happier

  • Some federation sender bugs have been fixed

  • Some database locks in the federation sender in SQLite mode have been fixed

Spec compliance has improved a bit:

  • Client-Server APIs: 48%, up from 45% last week

  • Server-Server APIs: 51%, up from 50% last week

timo said:


Hi everyone, here are some things we worked on this week:

  • Work on room tags (thanks to @gnieto)

  • Merged /logout/all endpoint (thanks to @CapsizeGlimmer)

  • Work on /joined_members (thanks to @CapsizeGlimmer)

Last week we had a list of major features still missing. Here's a list of what already works:

Registering, logging in, creating rooms, room visibility, join rules, basic permission management, public room list, inviting, creating DMs, e2e encryption, key backups, device verification, cross signing, notifications, uploading media/files (also user/room avatars), lower-resolution media thumbnails, voip calls and a few other thing's I'm forgetting right now. So it's useable for non-federating chats already.

Thanks to everyone who supports me on Liberapay or Bitcoin!


Neil reported:

In Synapse land this week, we shipped 1.16.0 and err 1.16.1.

Lifting from the blog post, the highlights are:-

  • An important performance fix to improve room state resolution.

  • An option to enable e2e by default for new rooms.

  • Ability to run multiple media repo workers side by side.

  • Ability to mark specific content as being safe from quarantine.

  • Bug fixes to make migrating from SQLite to Postgres more reliable - if you are running sqlite for anything other than evaluation purposes then please migrate!

We also put out a release candidate for 1.17.0 which all being well we’ll release on Monday. 1.17.0 is really a bug fix release the most notable being finally squashing a long standing bug that caused locally rejected invites to get β€˜stuck’ client side.

Continuing our performance theme, having now got the CS API largely into a good state of responsiveness, we are looking at federation lag. Today we shipped a sharded Federation Reader to which has reduced the average lag from seconds to milliseconds. We are just running two currently and are still tuning as we figure out how to get the best from it. Initial impressions seem promising. Watch this space.


We also have a PR out for review to shard the Federation Sender, which will have much the same effect in the other direction.

Once we have sending messages via the Client-Server API, much reduced federation lag and a sharded Pusher we’ll take a look at room joins.

Nico ( reported:

Not much to talk about currently, since I'm breaking my Nheko to replace the entire event store at this moment, but I have some heads up on an annoying bug that I fixed on my branch:

Sometimes we had a weird issue, where Nheko wouldn't load the language the user set on their system. This was especially annoying when I wanted to test a specific language, like Japanese, and I couldn't figure out the right LANG* variables to set the language to Japanese in Nheko. Turns out, this was a bug in Nheko and you wouldn't have guessed so, when looking at the examples in the Qt documentation. Anyway, KDAB wrote a nice blogpost explaining this issue:

If you are a Qt developer, you may want to check your applications, if you are also affected.

While not much is happening on the master branch some things happened on the Redesign branch:

  • Daydream does the sync now on a worker which is similar to using a thread

  • jplatte made a PR for optimizing multiple Parts of the Code which significantly improved the overall Daydream performance ( )

  • Some rework of the Login logic happened to prepare for well-known support

Dept of SDKs and Frameworks 🧰


Tulir offered:

When I initially implemented end-to-bridge encryption in mautrix-python, I used matrix-nio in a slightly hacky way to get it done quickly. It worked fine in some cases, but also caused some undecryptable messages. I tried switching to using matrix-nio's crypto module directly, but the sans-I/O design made that difficult: there were too many parts that needed to be hooked up to the actual I/O and I wasn't able to find them all. In the end, I just decided to implement the basic e2ee stuff directly in mautrix-python the same way it's implemented in mautrix-go.

All my bridges based on mautrix-python (Telegram, Facebook and Hangouts) have been switched to use the new crypto stuff. After a few initial bugs that are already fixed, it seems to work better than the old system. I'll probably add native e2ee to maubot soon too, which is my last main project that's still missing e2ee.

The Mozilla IoT Matrix Adapter can send posts based on events in your home.

Version 0.3 brings the ability to use room aliases instead of internal room ids. Furthermore, you can configure it to accept invites and follow room upgrades.

Due to utter negligence and malpractice by myself, we missed the update for this project last week. Of course, 0.2 is now superseded by 0.3, but here is the 0.2 update anyway:

Released v0.2.0 of the Mozilla IoT Matrix adapter. It's now possible to post in multiple rooms (still one per post).

Cat Disruptor 7000

Stephen D told us:

I wrote a pretty simple Matrix bot in Rust which is loosely based on Cat Disruptor 6000. It will react with 🐈️ to any message containing the string "cat" *. Since it is a small project, I hope it can be used as an example for other people interested in writing Matrix bots in Rust. It implements several important features (crypto/device store, auto-accepting invites, crafting custom events, etc.) You can host it yourself, or you can try it out by inviting the user "" to your room!

* Cat Disruptor 6000 does not do this (it is used for disrupting monologues with cat pictures). However, many instances of Cat Disruptor 6000 also include a separate bot, which is what Cat Disruptor 7000 is mimicking.


mr_johnson22 said:

matrix-imposter-bot - A bot that uses your account to repeat other people's messages. This gives relay-bot capabilities to puppet-only bridges.


  • Can be much more easily deployed with a production-level WSGI server. It comes with waitress but it's possible to use any other server.

  • Member join/leave/rename now post messages

  • Shuts down when receiving a term/exit/quit signal, instead of hanging

  • The Public Rooms API has been deprecated in favour of the Current State Server

  • Event size limits are now honoured with the correct return code

  • Invites have seen some refactoring and retiring invites should work better now

  • The federation sender now persists unsent PDUs to the database and will automatically retry when Dendrite is restarted, making resend behaviour much more reliable (particularly in the P2P demos)

  • Some room checks in /state and /state_ids have been fixed

  • Some additional restrictions have been added to /send and we now return the correct error codes

  • A bug where current state was incorrectly used when getting missing/backfill events has been fixed

The previous Fractal update was quite a while ago but we’ve kept busy.

There has been a lot of under the hood work that users won’t notice and which we won’t delve into. In addition to them, we have a few nice things:

  • Matrix API tokens are redacted in logs for better privacy when submitting bug reports.

  • A send button was added next the message entry. This is especially relevant for touch screens.

  • We are less noisy with typing notifications that we send out.

  • We support SOCKS proxies.

  • Notifications for non text messages have been tweaked.

  • We gained support for edited message display. They are replaced with the newer content and a little icon is shown next to them. Editing messages is not supported yet though.

  • Avoid including bridged user in directory lookups (

  • Add experimental multi-platform buillds for amd64 and arm64 platforms.

  • remove warning about matrix-synapse-ldap3 (




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

Slavi said:

it appears to be puppet week in matrix-docker-ansible-deploy-land!

Thanks to various contributors (Johanna Dorothea Reichmann, Tulir Asokan and Hugues Morisset), the playbook has gained support for 4 new bridges: mx-puppet-instagram (see our docs), mx-puppet-twitter (see our docs), mx-puppet-discord (see our docs) and mx-puppet-steam (see our docs).

This brings the total number of bridges supported by the playbook to 15!

Find it here: and join the discussion at!

Enjoy! ❀️


MTRNord offered:

Did you ever have the issue that a media event sent from someone is too large for your HS and you don't want to fiddle with the link?

IPFS Bot might be a solution. Invite or Check out to use the bot.

If you reply to any media event with !ipfs the bot will send you a link to the media stored on ipfs.

Known issues are:

  • E2EE not yet working (It joins but can't yet decrypt the related event)

  • Error handling is basically not existent. Therefore crashes might happen until I sort this out.

  • It currently does very verbose logging. This will be removed when the bot is more stable

  • Images sent from RiotX sometimes seem to not play nice with ruma

(Demo for the IPFS Bot):

We could include this video here, but it seems me appropriate to link to an actual IPFS location.

cody, REPL for your Matrix chat rooms

carl offered:

Hello, I am announcing my first matrix bot - cody - that will evaluate code snippets in your Matrix rooms and return the result. Here is an example interaction:

user> !py "Hello world!"
cody> 'Hello world!'

user> !py list(range(10))
cody> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

You can chat with him and view the source code at

This initial release only supports Python, but the plan is to add support for more languages in the next few weeks. The repo might also be of interest to some of you as it has CI, CD to DockerHub, complete dev environment with cody, pantalaimon, synapse and riot using docker-compose, simple metrics and Grafana-dashboards-as-code.

Matrix Notepad Version v0.2.2

KB1RD told us:

A real-time collaborative text editor using the Matrix protocol.

Nope, it's not dead.

  • New version of logootish-js with a completely new algorithm

    • In particular, I should note that this new algorithm is tested extensively, so I think the bugs should be out
  • Corresponding updates to internal event structure

  • Fixed UI & CSS bugs

  • Improved UX for room title editor

  • Currently, conflicting text will be displayed, but conflicts will not be indicated in any way

  • I almost forgot to mention: The room list is now filtered using the typed rooms MSC (event ID org.matrix.msc1840). is a room with that state event set.

I also made a flame graph of the internal algorithm and I'm surprised by some of the results. The good thing is that I think there's quite a few ways to speed up the algorithm. Here it is:{%22merged%22:false,%22nodeId%22:null,%22excludeTypes%22:[%22cpp%22,%22regexp%22,%22v8%22,%22native%22,%22init%22,%22core%22]}

It's demos this week!

  • Riot X video calls (valere)
  • Room list (TravisR)
  • Notifications - (Michael (t3chguy) & richvdh)
  • E2E Onboarding (Dave & Nad)

Dept of Spec πŸ“œ

anoa announced:

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:

New MSCs:

Spec Core Team

In terms of Spec Core Team MSC focus for this week, unfortunately our three MSCs from last week ( MSC2366 (verification flows), MSC2403 (knocking), and MSC2630 (SAS security)) are still pre-FCP. Most of the team has been quite busy with implementation for the past few weeks. Instead of advertising those 3 MSCs again, we're going to switch the focus to "implementation" for a bit until we're freed up again.

So the focus for this week is: MSC implementation work. However, this should not discourage any MSC authors from responding to MSC feedback in the meantime πŸ™‚


Dept of GSoC πŸŽ“

Ruma GSoC

devinr528 reported:

This week in the ruma/matrix Google Summer of Code project, ruma-events was made ready for use! After adding stripped and sync event generation to the event_enum! macro there were only a few small tweaks needed to try it out in some dependent rust crates. I spent a few days converting matrix-rust-sdk to use the ruma-monorepo. Since ruma is used on both client and server-side, I also opened a PR to update Conduit, a homeserver implementation written in Rust. To test that everything worked together, I updated rumatui, my command-line client written in rust.

Then I could test that Conduit sent, and matrix-rust-sdk received the new ruma events successfully. While updating, I felt the pain of not having accessor methods for the Any*Event enums to get at the event fields held within. I have opened a pull request to add the generation of these methods to the event_enums! macro. Hopefully, the Conduit and matrix-sdk PR's will be merged and the ruma monorepo can be tested in the wild!

matrix-ircd GSOC

karlik told us:

Moved matrix protocol, irc protocol, and bridge module to futures 0.3. Converted some utility functions to new futures, and updated the http implementation to use the standardized Hyper library instead of using a custom http implementation.


nikofil said:

  • Created PR for enabling e2ee across all services! This required a few changes to how the bot client is initialised, as well as changes to all services to use the new functionality instead of directly sending messages to a room.

  • Added code from another of tulir's projects to Mautrix to allow storing the crypto material (olm / megolm sessions, accounts etc.) in a SQL database, adding a second way besides using Gob storage.

  • Future plans are to work on the library itself to add any features that might be missing.

HTML embeddable chat rooms

arnav-t told us:

This week I've worked on the following features for the project "HTML embeddable chat rooms" under GSoC '20:

Added support for signing-in

Via sign-in popup

The user can enter their credentials into the modal dialogue box.

Via postMessage interface

    cmd: 'login',

    args: {
        user: 'username',

        passwd: 'password'

}, origin);


args (object):

  • username (string) - Username

  • passwd (string) - Password



    status: 'success', 
    message: 'Attempting sign in...'


Added support for default avatars

Using the same design as Riot. However, I am just using flexbox and text instead of drawing on an HTML5 canvas. The HSL color is generated by hashing the user ID.

Quoting and replying

Added on-hover buttons and reply popup above message composer similar to Riot web. Quoting prepends the message (quoted) to the message composer similar to Riot web and replying would also work similar to Riot web. It will be fully functional once markdown parsing is added.

Guest access

The client now supports guest access. If no access token or user ID is provided in the configuration file, the client attempts to register a guest account on the home server. Room contents are viewed using peekInRoom.

If the guest attempts to send a message, only then joinRoom is called to avoid spam (each page load would lead to a guest joining the room).


Chethan told us:

SAS Verification is completed and works !

Supports both Emoji and Decimal Verification Only uses curve25519-hkdf-sha256 as key_agreement protocol

Brand new UserProfile written entirely in qml.


Updated with needed APIs for SAS verification.


tyagdit reported:

Port to Matrix-nio

  • The matrix connector is now using matrix-nio!

  • Bots can send and receive texts, images, files as before

  • No change in configuration required, just update opsdroid and run as before

  • Encryption is not yet implemented

  • You can check out the PR here

Enabling E2EE

  • Sending and receiving encrypted texts, edits, replies works just as normal messages

  • Images and files are being worked on

  • User shouldn't have to change much about their configuration to use encryption

  • Some testing is due

  • Check out the progress here

Dept of Servers 🏒


Dendrite is a next-generation homeserver written in Go

kegan reported:

This week has been mainly about testing to ensure that all the progress over the past few months is kept up-to-date and correct. We've also added a few features in order to get certain sytests working. To that end:

  • Invites can now be declined over federation and they will be reflected in /sync responses.

  • Errors encountered when joining a room over federation are now sent back to the client.

  • Errors encountered when accepting an invite over federation are now sent back to the client.

  • Dendrite will now check server names meet the server name grammar in the specification.

  • A bug which caused client-api-proxy to not actually proxy correctly has been fixed, thanks @fantashley !

  • /send now abides by the limits in the specification: 50 PDUs / 100 EDUs.

  • The docker-compose scripts now include appservice_api, thanks @fantashley !

  • Sending invites over federation will now fall back to v1 if v2 fails with a 404.

  • Dendrite now implements room.timeline.limit completely (in both in-line and stored filter formats).

  • Dendrite now sets the limited flag on /sync responses correctly.

In addition, we now have support for collecting code coverage output from SyTest. This indicates we are testing roughly 70% of the Dendrite codebase. The remaining 30% are hard to reach via integration tests (e.g database failures, communication problems between internal APIs).

Spec compliance:

  • Client-Server APIs: 45%, up from 40% last week

  • Server-Server APIs: 50%, up from 38% last week

In total, we've made an additional 45 sytests pass this week.


Nico reported:

Mascarene v0.2.0 has been released.

This version implements a minimal set of client API endpoints to work with Riot and allow user registration,

room creation, invitation and messages sending on the same running instance (no federation support).

Docker image are also available. See this documentation

for rough installation instructions.

Conduit is a Matrix homeserver written in Rust

timo told us:

This week I finished the cross-signing PR:

To try it out yourself, open Riot (preferably and join the <> homeserver.

Thanks to everyone who supports me on Liberapay or Bitcoin!


Neil told us:

This week we’ve been working on further improvements to event persistence and ironed out a nasty bug where an unusually long state resolution could block the reactor overall and impact send times. We seem to have got to the bottom of this and has improved a lot as of today.

More generally we’ve been trying to characterise performance so that we can continue to improve over the coming months.

We are going to focus on:-

  • Client send event

  • Outbound Federation Latency

  • Inbound Federation Latency

  • Room joins

As well as tracking the CS API generally.

We are using apdex with a satisfied limit of 250 ms and a tolerating limit of 1000 ms. By the end of the Summer we will aim to hit an apdex score of 0.9 for each area.

For instance here is Federation Send Event Apdex graphed overtime. You can see that we are averaging about ~0.8 currently, so plenty to keeping us busy!


Next up will be to work on Outbound Federation Latency

Aside from that we’ve been working hard on the upcoming Notifications improvements. Mapping the push rules to the demands of the UI has been challenging and we’ve been through several iterations. If you’d like to learn more take a look at Michael and Rich’s explanation in this week’s Matrix Live. Rich’s presentation has Sheltie pictures #justsayin’

Dept of Bridges πŸŒ‰

It's a Tulir kind of week.


Tulir told us:

The WhatsApp bridge got a bunch of improvements this week, such as:

  • Matrix -> WhatsApp gif bridging

  • Bridge status notices if your phone battery is low

  • A command to get group invite links and another command to join groups using invite links

  • Matrix <-> WhatsApp bridging of most membership changes


Tulir reported:

The Messenger bridge mostly got bugfixes, but also Matrix->Facebook bridging of all media and location messages


Tulir offered:

The Telegram bridge now supports logging in by scanning a QR code, although it requires using the master branch of Telethon instead of a release. I also fixed bridging captions in file messages, so they're now bridged as separate messages like with images

Half-Shot bridges roundup

Half-Shot offered:

Hey all, I've got several releases to talk about this week!

First, matrix-appservice-slack has been updated to 1.4.0 with several quality of life changes such as automatically setting the bot profile on startup, supporting logging out of slack accounts and adding a health checkpoint. There are also quite a few bugfixes so make sure you update.

matrix-appservice-irc was also bumped to 0.18.0 with the headline features being Node 14.x support.

We've also shipped 0.19.0-rc1 which has stopped support for Node 10.x. Why? Because we're adding worker support to the bridge! This release starts to make use of the new(ish) worker_threads feature so that we can dish out processing to separate threads (running their own UV event loops, for node enthusiasts). The first thing to be workerized is metrics, so that metrics may still be reported should the bridge become saturated, but we plan to split out more work as things progress.

Finally matrix-appservice-bridge got a few fixes to support our new worker land, as well as being updated to support matrix-js-sdk 6.0.0. You can checkout the changes for 1.13.1 here.

Dept of Clients πŸ“±


sorunome offered:

miruka* reported:

0.5.2 is now out:


  • Sessions/device list: you can now inspect, rename and manually verify

    your devices from the account settings page. The interface is still work in progress, keyboard navigation and signing

    out sessions will be added in a next version.

  • Re-add client-side unread/highlight room indicators.

    If your account has push notifications disabled, which precise cross-client counters depend on, the local indicators will be used as fallback.

  • Support the MIRAGE_CACHE_DIR environment variable to override where

    files and thumbnails are downloaded

  • A bunch of theme additions, check the full log


  • Overhauled account settings to match the design of other tabbed pages.

    The horizontal layout design has been removed due to complicated code and being impossible to extend without breaking it.

  • The display name field in account settings is now colored,

    preview your new display name's color as you type

  • For rooms without image avatars set, the room settings's avatar color now

    responds to the name field as you type

  • Overhauled scrollbars:

    • Now match the Mirage theme and much better visibility

    • No more right margin for the timeline's bar

    • Minimum height to prevent the bar from becoming impossible to grab

  • Use brighter text for room names of rooms that have unread messages

  • Buttons, tabs, text fields and areas now have animated bottom borders

    to represent keyboard focus instead of being highlighted like when hovered

  • Text fields and areas can now have rounded corners, following the theme

  • Tabbed pages (Sign In, Add Chat, etc) can now be swiped left and right

  • Popups can now be scrolled when their content is bigger than the

    window's height

  • Replace most generic checkmark icons for apply buttons in popups

  • Pressing escape in forms will consistently trigger corresponding

    cancel buttons




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:

  • Most of our time this week was spent trying out device verification with Chethan. It's fun and I could finally file bugs in Nheko against someone else!

  • We fixed some issues that should hopefully make text in the timeline less blurry again.

  • Fixed a bug which cause some clients like fluffychat to break in E2EE rooms (we accidentally sent a null relation when not replying...)

  • Fixed an issue, where Nheko didn't verify the format of html formatted messages correctly, causing it to render messages in a way which wasn't compliant to the spec.

  • Thanks to the work of a Pirate and his friends, current versions of Nheko should be available in backports for Debian Buster once again!

Riot Chat for Nextcloud

Gary Kim announced:

Riot Chat for Nextcloud 0.5.0 The new version updated the version to 1.6.6 and added the ability for admins to set their own custom config for Riot rather then using the settings interface in addition to a few bug fixes.

Riot Chat for Nextcloud allows individuals and organizations with a Nextcloud instance to easily set up and configure their own Riot instance with just a few clicks on a web interface without the need to write a config file.

Manu told us:

This week, we completed UX for cross-signing and secure backup. We made associated settings but we still need to polish them.

Sygnal and the new push extension have been updated to match Apple requirement and our privacy concerns. Events content are no more sent anymore. We started to implement the new room notifications settings UI.


benoit told us:

This week we were mainly working on cross-signing, room settings, VoIP stabilization and performance improvement.


benoit reported:

We will publish at the beginning of next week a beta version of the migration to RiotX codebase on the beta channel of the PlayStore, to be able to ensure the migration works fine, before release it to production.

Dept of SDKs and Frameworks 🧰

  • Add ability to register using Homeserver.register

  • Add VideoMessageEvent

  • Add Room.canonicalAlias and Room.alternativeAliases

  • Add format field to TextMessage (thank you Cyril!)

  • Remove equatable dependency

Get it on pub!


joepie91 discovered this project, presented yesterday at Conference in the Cloud:

Net::Matrix::Webhook implements a webhook, so you can easily post messages to your matrix chat rooms via HTTP requests. It uses IO::Async to start a web server and connect as a client to matrix. It will then forward your messages.

matrix_scrape_emoji_translations script project

sorunome announced:

Soru wrote a quick program that scrapes riot-web, riot-x and riot-ios for translations of the emoji names for emoji verification and combines them all into an easily-readable json file, so that other client developers can use it. Since all three riot versions have a different set of translations, it might also be helpful for them. You can find the source code along with the outputted json files here.

Dept of Bots πŸ€–

"Scandinavia and the World" comic bot
