Synapse 1.19.1 released

27.08.2020 12:26 β€” Releases β€” Brendan Abolivier

Synapse 1.19.1 is a bug fix release to fix two bugs introduced in 1.19.0.

Those two bugs were related to the new rate-limiter on room joins, which was introduced in 1.19.0.

The first bug caused Synapse to ignore exceptions to rate-limiting for application services.

The second one prevented profile updates from being correctly propagated across rooms.

Sorry if you have been bitten!

Get 1.19.1 from github or any of the sources mentioned at

Changelog since v1.19.0

Synapse 1.19.1 (2020-08-27)

No significant changes.

Synapse 1.19.1rc1 (2020-08-25)


  • Fix a bug introduced in v1.19.0 where appservices with ratelimiting disabled would still be ratelimited when joining rooms. (#8139)
  • Fix a bug introduced in v1.19.0 that would cause e.g. profile updates to fail due to incorrect application of rate limits on join requests. (#8153)

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

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.


Pierre reported:

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

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!

Dept of Clients πŸ“±

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


Dept of SDKs and Frameworks 🧰


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.

Dept of Ops πŸ› 


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

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.

Synapse 1.19.0 released

17.08.2020 00:00 β€” Releases β€” Neil Johnson

Synapse 1.19.0 is here and ready for action.

1.19.0 contains lots of async/await changes, 27 separate PRs to be precise(thanks Patrick). These changes will provide some level of performance improvement, but the real value to us is that it will improve our ability to profile Synapse more effectively.

It also features 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.

Some admins will rejoice that we have added a /health end point to every configured HTTP listener which should make it easier to monitor multi-worker installs.

Finally 1.19.0 contains improvements to the Admin API allowing the admin to optionally purge rooms on deletion.

Get the new releases from any of the usual sources mentioned at 1.19.0 is on github here.

Changelog for 1.19.0 follows:

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.

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

If Ansible were a film franchise "Ansible: The Collection" would be the long awaited boxset.

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.

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.

indiechat announced:

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 ☺️

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.

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.

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.

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.

Synapse 1.18.0 released

30.07.2020 18:34 β€” Releases β€” Neil Johnson

Synapse 1.18.0 has landed.

The most important thing to know about 1.18.0 is that it contains support for sharding multiple workers. Specifically this means being able to run multiple federation senders, multiple client readers to handle registration and multiple push workers. This will be important for anyone running a large scale install of Synapse. You can read more about how to benefit from these changes in docs/ In the same spirit we also moved typing notifications from the main process.

Aside from that, we have new admin API support to list the users in a room, support for oEmbed for media previews (you can unfurl tweets again!) and a general slew of federation bug fixes.

Get the new releases from any of the usual sources mentioned at 1.18.0 is on github here.

Changelog for 1.18.0 follows:

Synapse 1.18.0 (2020-07-30)

Improved Documentation

  • Update worker docs with latest enhancements. (#7969)

Synapse 1.18.0rc2 (2020-07-28)

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.

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!

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.

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.

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!

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:

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.

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.

Feel free to use it πŸ™‚


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


Chris Vincent reported:

Related to my previous update here, I've just published an initial version of a Matrix Client-Server client library for the Crystal programming language:

Is this the first time we've seen tooling for Crystal?

Dept of Ops πŸ› 


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

Slavi announced:

matrix-docker-ansible-deploy is now ready to help you with the Riot -> Element transition.

We have a few ways to handle the migration depending on how much change and breakage you're willing to tolerate. See our Migrating to Element documentation page.

Incredibly thorough migration paths here!

Dept of Bots πŸ€–

Matrix-Alertmanager bot v0.3.0

jaywink offered:

Matrix-Alertmanager bot has a new release of v0.3.0. Highlights are compatibility with AWS Lambda, better error handling if message fails to send and the ability to do a @room mention on firing alerts. Find it here.

cody 0.6.0

carl reported:

REPL for your matrix rooms

This week, we got support for javascript (nodejs) with !js. The code

complexity was considerably reduced, which should make adding new languages much easier in the future. All Python sub-dependencies are now pinned, making

cody builds even more reproducible.

Noteworthy (Matrix over Wireguard overlay networks)

balaa said:

Noteworthy team (patrick and myself) have open sourced both components (spoke & hub) of Noteworthy (Matrix over Wireguard overlay networks -- we are actively welcoming testers/contributors and working with a handful of projects on incorporating our deployment model over in -- it is also the fastest way (less than a minute) to deploy your own home server! Also, working on incorporating Noteworthy into the popular ansible deployment repo to enable users who don't have access to a publicly accessible to deploy their own home servers.

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.
