Matrix Live 🎙

Google Summer of Code - GSoC -- Final Call: put your seatbelts on!

From Nico (@deepbluev7:neko.dev), who is assisting with GSoC admin this year:

As already mentioned a few times, this year the Matrix organization is taking part in GSoC again. This is an amazing opportunity for students to take part in various Matrix-related projects and helping those projects implement awesome new features. Submission for this closes on April 13 this year (which is Monday on my clock)! If you want to take part in GSoC as a student, submit your final proposals now! You can find some examples here: http://matrix-org.github.io/gsoc. If you want to submit your own ideas, please contact a potential mentor before that. If you have questions, please check out the #gsoc:matrix.org room.

If you have already been writing a proposal, now is the time to put on the final polish and submit your proposal. If you are interested, now is the last opportunity this year to submit your proposal! We are excited to see, who will want to take part this year!

Dept of Spec 📜

Spec

anoa said:

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 https://matrix.org/docs/spec/proposals.

MSC Status

Closed MSCs:

• MSC3087(MX-EXT0000): Standardised extensions

Merged MSCs:

• MSC2312: Matrix URI scheme proposal

MSCs in Final Comment Period:

• MSC2190: Allow appservice bots to use /sync (postpone)
• Pushing updates about Groups (Communities) to clients (close)

New MSCs:

• MSC3105: Previewing UIA flows
• MSC3089: File tree structures

Spec Core Team

After a lot of work behind the scenes, we've now officially unfrozen the spec! 🧊 🔨

This means spec PRs that change the actual content of the spec can be made again, and made they certainly have been! Huge thanks to TravisR for writing all of those up (and others for reviewing!), and for the last push of removing all of the old spec toolchain from the matrix-doc repo.

With this out of the way, we move forward migrating the old spec pages over to the new site, as well as to the next release of the spec, which will feature a new global versioning scheme!

Dept of Servers 🏢

Synapse

Synapse is a popular homeserver written in Python.

callahad offered:

Ding dong the snake is dead! 🐍☠️

We released Synapse 1.31 on Tuesday. There are certainly nice things in it (read the release notes), but also, two days after that... WE FINALLY REMOVED SUPPORT FOR PYTHON 3.5!

As part of that, we now have a formal deprecation policy that explicitly states our platform support strategy. Namely: we follow upstream lifecycles. Thus, we can say with confidence that we will drop support for Python 3.6 in December of this year. So when upgrading, please do ensure that your operating system of choice provides modern Python packages.

By the way: if you're looking to contribute to Synapse, now is a good time to start grepping for 3.5 or xenial or stretch and seeing what cobwebs turn up which can finally be swept away. 🕸🧹

We're also experimenting with using GitHub Actions for CI, and would certainly appreciate reviews and pull requests from folks who are more knowledgeable in that area, especially around speeding up workflows and caching.

We'll be back next week with more details on the specific quarterly goals the team is committing itself to, but until then, 👋!

I don't know specific change helped, but 1.31 is a noticeable performance improvement for my Synapse, so thanks team!

Conduit

• Conduit: A Matrix homeserver written in Rust https://conduit.rs
• Ruma is a set of Rust library crates around Matrix

timokoesters told us:

Done:

• Fix media thumbnail generation

• Fix appservice detection

• Implement room account data endpoints

• Big state resolution refactor to make it easier to understand

• Use correct room versions

• Submit bug reports to libraries and clients:

  • https://github.com/vector-im/element-android/issues/3065

  • https://github.com/ruma/ruma/issues/446

  • https://github.com/ruma/ruma/issues/447

Doing:

• Thinking about the future of the sled database in Conduit: https://gitlab.com/famedly/conduit/-/issues/74

• Investigating state resolution problems

• Investigating why certain clients are not supported by Conduit

Motivations & Challenges:

• Some state resolution bugs are (still) very nasty and hard to debug

• A deadlock was causing the whole program to freeze. The cause was found.

• Our #conduit room had a state reset (it's on room version 5), so we upgraded to version 6, which was annoying

matrix-registration

zeratax offered:

Been a while since I last updated twim about matrix-registration.

Since then we added the possibility to localize the project and already got translations for

german, portuguese and chinese! https://l10n.dmnd.sh/engage/matrix-registration/

there has also been work on a nix package and module over here:

https://github.com/NixOS/nixpkgs/pull/107654 and a nur package to test it right now:

https://github.com/ZerataX/nur-packages/blob/master/pkgs/matrix-registration/default.nix https://github.com/ZerataX/nur-packages/blob/master/modules/matrix-registration.nix

But here are the newest changes for the just released v0.9.0

Features

• now uses alembic to up- or downgrade the database scheme

Please run the following after every update to make sure your database scheme is uptodate

alembic upgrade head

• instead of one time token you can now set arbitrary amounts of usage per token via

 *m, --maximum INTEGER     times token can be used

• new option in the config file to log IPs to the database

these are viewable by checking the status of individual token via the cli or web api

Changes

There have been a lot of changes to the config file and web api,

please refer to: https://github.com/ZerataX/matrix-registration/releases/tag/v0.9.0 and make sure to check the sample config for other changes you might have missed

Get it here

• pypi: https://pypi.org/project/matrix-registration/0.9.0/

• docker: https://hub.docker.com/repository/docker/zeratax/matrix-registration

and as always feel free to join #matrix-registration:dmnd.sh for support or w/e else!

Kubernetes

Ananace told us:

Updated my Kubernetes chart - and image, for those still using it - to the new Synapse 1.31.0 release.

Dept of Bridges 🌉

matrix-puppeteer-line

Fair announced:

matrix-puppeteer-line: A bridge for LINE Messenger based on running LINE's Chrome extension in Puppeteer.

New features:

• Sending & receiving images

• Sending Matrix stickers

• Receiving LINE stickers

• Receiving LINE emoji (via [MSC2545: Emotes](https://github.com/Sorunome/matrix-doc/blob/soru/emotes/proposals/2545-emotes.md ))

TODOs:

• Rework message syncing so that receiving a message doesn't require "viewing" the LINE chat in the Puppeteer-controlled browser, which will make LINE send a read receipt even though you may not actually have read the message yourself.

• Try to conclude whether bridging LINE stickers & emoji breaks copyright and/or would cause any other legal issues...! And look for something more threatening than just the Terms of Use (relevant section is 10.3). Any advice regarding this would be much appreciated 🙂

Discussion: #matrix-puppeteer-line:miscworks.net

iMessage bridge hinted

Tulir offered:

I sent some messages between two Element web instances this week.

<@jboi:jboi.nl>: is that an iMessage bridge? 👀

yes, but there's no Mac involved

Dept of Clients 📱

Hydrogen

A minimal Matrix chat client, focused on performance, offline functionality, and broad browser support. https://github.com/vector-im/hydrogen-web/

Bruno reported:

After finishing push notifications last week, this week I've been getting on top of the bugs that had previously come in, before getting to more feature work. There were 3 releases with 7 bugs fixed, the last release being 0.1.45 just now.

Nheko

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

Nico (@deepbluev7:neko.dev) offered:

For people that use our Nightlies and Windows at the same time, we fixed our nightly builds for Windows now.

For people often going to the TWIM room, we fixed "TWIM" now actually finding the #thisweekinmatrix:matrix.org room. (We also fixed a lot of other small issues on the side, that are less interesting and hope we can tie a release soonish. :3)

Rather meta, that this fix relates so specifically to TWIM.

NeoChat

Tobias Fella offered:

In the last weeks, we have landed several smaller features:

• Quick reply: Press Ctrl+Up to reply to the last message

• Quick edit: Press Up to edit your last message

• React with arbitrary texts using /react

We also fixed a lot of smaller issues, including joining rooms from the global room list, emotes, some commands and deletion of images and added lots of visual improvements. We're still investigating a bug that makes NeoChat get stuck on startup, and some fallout from our recent redesign of the timeline.

Element Clients

Updates provided by the teams.

Delight

• We’re iterating on private spaces, working towards making them publicly testable first on the Web & Android, with iOS to follow.
• MSC3083 (Restricting room membership based on space membership) has more details on spec changes.
• If you have Spaces enabled in labs on the Web or Android come join us in the Matrix Test Space
• And big thank you to everyone giving feedback in the Spaces feedback room, please keep it coming and as a reminder if you run a public community (on any platform) we’d love to chat to you to get closer to understand your problems and goals.

iOS

• The olm library is now available through Swift Package Manager. Instructions can be found at https://gitlab.matrix.org/matrix-org/olm/-/tree/master/xcode.
• Element-iOS 1.3.0 is almost ready to be shipped. A public TestFlight will be available over the weekend. It has an entire new text composer with changes in the layout around the room timeline. It contains several fixes in the notification extension to avoid “Unable to decrypt” errors and out of memory crashes.
• We made good progress on the new design for VoIP but we preferred to polish it even more. It will be available in another version.

Android

• Element Android 1.1.4 has been released to the beta testers. This version includes lots of optimizations. Full changelog: https://github.com/vector-im/element-android/releases/tag/v1.1.4. This release should be available to all users and to F-Droid users next week. The matrix SDK2 v1.1.4 has also been released today.
• We are making good progress to implement the Spaces, which will replace the communities (AKA groups). Spaces will be available in the release 1.1.5, behind a lab flag.
• Behind the hoods, we are making lots of code cleanup and we are improving the Matrix SDK API.

elmussol let us know that Element Android 1.1.3 is already available on F-droid. I love getting a new Element Android update!

Dept of SDKs and Frameworks 🧰

Polyjuice Server 🧙

uhoreg offered:

There is a new library in the wizarding world: Polyjuice Server, an Elixir library to help with writing Matrix homeservers. It is still in the very early stages, but it is starting to take form. Please note that this is just a library and not a homeserver implementation, as I don't want anyone to mistake this for something that's actually useful. (And now that I've scratched this itch, I should attend to my secret personal side-project that I've been neglecting...)

In 20 years, will we look at this small comment from uhoreg and say, that's the first hint of the project that would change the world?

maubot

Tulir said:

I finally started writing some plugin development docs for maubot. It doesn't cover everything yet, but you can find it at https://docs.mau.fi/maubot/dev/getting-started.html. Setup docs were also moved from the GitHub wiki to docs.mau.fi and some of those docs have been improved (e.g. it now has instructions for enabling e2ee)

Guile-Deck: GNU Guile SDK for Matrix

a_v_p told us:

I released Guile-Deck 0.2.0, a GNU Guile SDK for the Matrix network: https://github.com/artyom-poptsov/guile-deck/releases/tag/v0.2.0

libkazv (and the Kazv Project)

tusooa reported:

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

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

forward bot between matrix and tencent qq. Talk to us on #kazv:tusooa.xyz .

Updates

In the past 2 week we ("tusooa and her longcat," we hope someday we can

remove this annotation :P):

1. Added Boost.Serialization support https://lily.kazv.moe/kazv/libkazv/-/merge_requests/4

Dept of Ops 🛠

matrix-docker-ansible-deploy

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

For german speakers: my matrix talk from the Chemnitzer Linux Days is now online.

Dept of Interesting Projects 🛰️

Cactus Comments 🌵

Asbjørn told us:

Cactus Comments is a federated comment system for the open web built on Matrix.

Web Client v0.7.0 released! This one includes two new configuration options.

• New configuration option: loginEnabled changes the login button to be a matrix.to link, if set to false (default is true).

• New configuration option: guestPostingEnabled requires users to log in using their Matrix account, if set to false (default is true).

• Added HACKING.md, a guide to getting started with hacking on the client.

/ipns/latest.cactus.chat is updated to point to the latest release, so sites linking there should already be using the new version.

Come play with the demo: https://cactus.chat/demo

Join our Matrix room: #cactus:cactus.chat

Also, watch Matrix Live! If you've already done so, watch it again.

Matrix in the News 📰

Famedly-folk on LinuxLounge

Nico (@deepbluev7:neko.dev) told us:

If anyone understands German and listens to podcasts, Krille Fear and I will be on the LinuxLounge on the 25th of April: https://social.tchncs.de/@theradiocc/106025736391026211

In fact there are dozens of people who understand German, and surely some subset of these listen to podcasts. With these conditions accepted, the LinuxLounge appearance will go ahead.

That's all I know 🏁

See you next week, and be sure to stop by #twim:matrix.org with your updates!

We've released Synapse 1.31.0!

Mainly internal changes this time (type hints, code lints, etc.) but we've also landed some initial work on MSC2946: Spaces Summary. And speaking of MSCs, Synapse 1.31 has an experimental flag which can enable support for the draft MSC3026: "busy" presence state.

Synapse 1.31 can now restrict OpenID Connect logins based on userinfo attributes (Thanks, HubbeKing!).

This release fixes a rare infinite loop when fetching cross-signing keys or handling device list updates, and further improves the speed of federation catchup. It also makes Admin APIs around user reactivation behave correctly when account passwords are disabled.

See the Release Notes for further information.

The Final Python 3.5 Release

This is the last release of Synapse to support Python 3.5 or PostgreSQL 9.5, and the last release of official packages for Debian 9 (Stretch) and Ubuntu 16.04 LTS (Xenial).

Future releases of Synapse will follow upstream end-of-life dates for Python and Postgres.

Accordingly, we anticipate ending support for Python 3.6 and PostgreSQL 9.6 in December of this year. We will also cease producing packages for Ubuntu 18.04 LTS (Bionic) at that time.

Thank You

Synapse is a Free and Open Source Software project, and we'd like to extend our thanks to everyone who contributed to this release, including ankitdobhal, blakehawkins, dklimpel, fuzzmz, HubbeKing, languitar, sandhose, and ShadowJonathan.

Introduction 🃏

Just keep the date in mind as you read these updates from the community. 😉

Matrix Live 🎙

Dept of Spec 📜

kegan reported:

MSC3079: Low bandwidth CS API is now up, feedback is welcome! Low bandwidth will increase mobile battery life, allow Matrix to be used over low bitrate links (1-5Kbps) and even allow push notifications to be done natively over Matrix (as /sync is now efficient)! We'll be experimenting with this some more and hopefully even enable it on some servers like dendrite.matrix.org in the near future.

anoa told us:

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 https://matrix.org/docs/spec/proposals.

MSC Status

Merged MSCs:

• MSC2801: Make it explicit that event bodies are untrusted data

• MSC2557: Proposal to clarify spoilers

• MSC2403: Add "knock" feature

MSCs in Final Comment Period:

• MSC2312: Matrix URI scheme proposal (merge)

New MSCs:

• MSC3079: Low Bandwidth CS API
• MSC3077: Support for multi-stream VoIP

Spec Core Team

The Spec Core Team had another retro this week. We're happy with the increased amount of MSCs flowing through the pipeline, but there's still a huge amount of work to get through, mainly revolving around prioritisation.

Don't let that keep you from sending in your well-formed MSCs however - the more the merrier!

New Spec Platform

The unstable version of the spec now lives entirely on https://spec.matrix.org! Redirects have been put in place from the old spec to the new for unstable. Stable versions will be moved over in time (and the redirects will hopefully better preserve url paths!).

We're also planning to unfreeze the spec shortly so that spec PRs can start flowing again. We now just need to clear up the old buildtools from the matrix-doc.

Dept of Servers 🏢

Synapse

callahad offered:

🚪Knock, knock? MSC2403: Add "knock" feature was merged! Now we have a stable target to aim at for implementing knocking support in Synapse. Knocking is part of (well, the entirety of) the forthcoming room version 7.

Not much else to report this week -- it's been a short week, and much of the team is heads down figuring out goals for Q2. With the start of the new quarter, a few Element employees are rotating their responsibilities: richvdh has wrapped up his work on social login and will be focusing more on core platform, with clokep shifting to focus on Spaces. Meanwhile, babolivier will come back into Synapse / Sygnal / Sydent land.

From all of us the Synapse team, we hope you have a great weekend and we'll see you next week!

Dept of Bridges 🌉

mautrix-whatsapp

Tulir announced:

v0.1.6 was released today. Some of the main changes since v0.1.5:

• Improved connection reliability and auto-reconnection, including auto-resending queued messages after reconnecting.

• Basic support for broadcast lists (WhatsApp's mass DM feature).

• Option to re-sync chat and user metadata less aggressively to avoid WhatsApp rate limits on big accounts (if you get 599 errors, enable this).

Full changelog on GitHub: https://github.com/tulir/mautrix-whatsapp/releases/tag/v0.1.6

Dept of Clients 📱

Nheko

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

Nico (@deepbluev7:neko.dev) announced:

Big announcement day! It's been a long time cooking in secret, but today Nheko finally got legs!

We are happy to announce, that Nheko got aquired by Google and will now be shipping on Android!

Google already contributed a few important improvements. All your messages are now sent in rainbow colors, because inclusivity is very important and we feel like no color should get excluded in a message. _{We also merged some crypto code to make indexing messages easier and help governments to protect our users.}

With great new things sometimes also come sad things. As such we sadly have to announce, that Windows, macOS and Linux will now be degraded to secondary platforms. Primary development target will just be Android and Haiku. The former is the most widely used operating system nowadays and Haiku is the only actual desktop operating system. We are sure this won't lead to such a degraded experience on those platform, just because they are now effectively unmaintained.

We hope you love this day as much as we do and if you are not reading this at the day of publication, we ask you to please check the date and mark it in your calendar, so that we can celebrate next year!

If you are reading this at a later day, please consider the following changes canonical:

• LordMZTE contributed the /rainbow command, which makes Nheko finally a client, that can be taken seriously.
• LorenDB has been having some fun building Nheko for Android. This may actually become supported in the future, but so far they are just experiments.
• red_sky fixed the certificate errors on macOS.
• You can now leave rooms by using the /part or /leave command.
• salahmak made the upload widget close, when you press the escape button
• A few other misc fixes here and there.

That's everything and have a lovely day!

Watch The Matrix

Doug said:

Update: I’ve made the following changes to Watch The Matrix since first sharing it:

• Reactions and Edits are shown properly.

• Redactions now work for messages.

• Rooms indicate if they’re unread and send a read receipt when opened.

• Older messages can be loaded in a room.

• Data is persisted so it’s no longer performing a huge sync on each launch! The initial sync is hopefully much lighter too.

• Sync errors are now shown at the top of the room list.

• A few basic localisations (aka Google Translate) have been added.

New room: #watchthe:matrix.org

Element Client Updates

From the teams:

Delight

• Spaces
  • We’ve been iterating on our initial implementation of private spaces, including getting the first parts of restricting room membership to space membership in Synapse
  • We’re also breaking out larger MSCs into smaller ones, like this draft on space membership.

Web

• 1.7.24 released on Monday
  • Additional VoIP call connection reliability improvements
  • Added invite option to room tile context menu
  • Improved cross-signing login flow
• On develop
  • Added prompt before quit in desktop
  • Fixed recovery key loop at login
  • Indexing errors added to settings

iOS

• We made 1.2.7 (https://github.com/vector-im/element-ios/releases/tag/v1.2.7) available on the App Store.
• We continued to iterate and polish the new text composer. You can preview changes in videos in our PRs: https://github.com/vector-im/element-ios/pull/4146, https://github.com/vector-im/element-ios/pull/4151
• The code that manages background syncs for the notification extension has been refactored to limit RAM usage. It will fix the out of memory crash.

Dept of Guides 🧭

Decentralisation/interoperability guides

Bram told us:

Two weeks ago, we held elections in the Netherlands and I went around the bigger political parties to ask them what concrete goals/ideas/plans they had to fight big tech companies.

And the best concrete solution I've heard, I'm not kidding, was that they're happy with the GDPR and that they want to keep that.

Knowledge of the internet is pretty dire in the EU, and I wanted to educate people a little. So I made a video explaining what a decentralized open communication network is: https://youtu.be/v5Y8zCwIxjI

Additionally, I wrote an article for people and politicians to read through, where I share my opinion on how and why the EU should encourage companies to allow for interoperability: https://noordstar.me/b/decentralize.md

That's all I know 🏁

See you next week, and be sure to stop by #twim:matrix.org with your updates!

Synapse 1.30.1 is now available. This release is identical to Synapse 1.30.0, with the exception of explicitly setting a minimum version of the Python Cryptography library to ensure that users of Synapse are protected from yesterday's OpenSSL security advisories, especially CVE-2021-3449.

Note that Cryptography defaults to bundling its own statically linked copy of OpenSSL, which means that you may not be protected by your operating system's security updates.

It's also worth noting that Cryptography no longer supports Python 3.5, so admins deploying to older environments like Debian 9 (Stretch) or Ubuntu 16.04 (Xenial) may not be protected against this or future vulnerabilities.

The next release of Synapse will be the last to support Python 3.5.

Hey everyone!

Dept of Servers 🏢

Synapse

callahad told us:

We're proud to announce that Synapse 1.30.0 was released on Monday.

(...and 1.30.1, today, in response to yesterday's OpenSSL advisories)

The 1.30 release focused on improving our resilience to interruptions in federation, both being smarter about what work we do, as well as improving the CPU and DB performance of the state_ids endpoint by at least an order of magnitude. Check the release post for full details.

...but also check out this graph (of that endpoint only) from an EMS host after deploying 1.30.0:

That ain't gonna bother us no more.

In other news, we've decided to try out GitHub Actions for automated testing of Synapse and will report back in a few weeks. Our hope is that this makes our CI more amenable to iterative improvement and outside contributions.

It's also worth flagging that the next release of Synapse, due in early April, will be the last to support Python 3.5.

See y'all next week!

matrix-media-repo

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

Kubernetes

Ananace said:

Finally did what I've been talking about for a while, and got the Synapse chart I'm doing upgraded to the point where it won't require my own image any more, Version 2.0.0. (In fact, the chart will now deploy the upstream matrixdotorg/synapse image by default)

I also went through and fixed a bunch of things, refactored the worker config some to get it closer to the generic_worker setup, added configuration to include arbitrary values in .well-known (for Jitsi and the like), etc.

They've also added:

And just updated my Kubernetes image and Helm Chart for Synapse to the new 1.30.0 version - note that the image has been deprecated by now though, the chart is the new go-to way to get Synapse on Kubernetes.

And then, following today's 1.30.1 Synapse update:

I've pushed Helm Chart updates for Synapse 1.30.1 and Matrix Media Repo 1.2.6

Element Clients

Updates from the teams:

Delight

• Spaces are now testable on develop.element.io & matrix.org! Buyer beware: They’re in early beta, using unstable prefixes, so may break at any time. But you can test by enabling the Spaces labs flag while connecting to matrix.org or a Synapse development build
• If you’d also like access to a test build for Android, we’re working out a better way to deliver test builds, but in the meanwhile let us know in the new spaces feedback room
• There’s lots of rough edges, but we’re first focusing on polishing public spaces, and feedback is welcome in the spaces feedback room, or via GitHub issues
• If you run an online community (using any platform), we’d love to talk to learn more about your general pains too, in you guessed it: the spaces feedback room
• Watch this week's Matrix Live for a demo of the above!

VoIP

• Not too much news this week, but look out for another connectivity fix in next week’s element web release.

Web

• Element Web 1.7.24-rc.1 on staging, including:
  • Additional VoIP call connection reliability improvements
  • Added invite option to room tile context menu
  • Improved cross-signing login flow
• On develop / nightly:
  • Improved invite error handling
  • Search indexing errors now properly state the error, instead of asking you to use desktop (when you already are)

iOS

• Element-iOS 1.2.7 is already available from TestFlight and will be available on the App Store on Monday.

🌵 Cactus Comments

Asbjørn offered:

Cactus Comments is a federated comment system for the open web built on Matrix.

Web Client v0.6.0 released! No new features, just UI/UX improvements this time around.

• Move matrix.to link into login modal.

• Removed login status string above textarea.

• Show userid in Post button.

• Add placeholder text to comment textarea.

• Textarea inherits background color, to work better with darkmode websites.

• dev.html example page now has a darkmode toggle button.

• A bunch of smaller improvements to the default CSS.

/ipns/latest.cactus.chat is updated to point to the latest release, so sites linking there should already be using the new version.

If you forked the CSS to style it yourself, you may want to replace it with the new CSS file and add your changes again, to get the new styling.

Final Thoughts 💭

nikgraf reported:

Hey everyone 👋 One year ago I started to explore combining CRDTs with end-to-end encryption (Matrix's Olm/Megolm) to allow people to collaborate on the same documents/data. Couple months back I got a first prototype working and then evolved to a production ready app. Think of a simple Google Docs, but end-to-end encrypted and offline-first (iOS & Android for now).

Feedback, ideas and question are very welcome!

Website: https://www.serenity.re/en/notes

The app/client source is available here: https://github.com/SerenityNotes/serenity-notes-clients

This is not a project built directly on Matrix, but I thought it was a very cool use of Matrix's end-to-end encryption library, olm!

That's all I know 🏁

See you next week, and be sure to stop by #twim:matrix.org with your updates!

We've released Synapse 1.30.0!

A key theme of this release was stability and resilience around federation. We've landed changes to be less eager about entering catch up mode and to retry on HTTP 500 errors, while also rejecting transactions which arrive before we've completed processing earlier transactions from that same server. We've significantly optimized how we handle missing events when receiving incoming federation traffic, and we've found a way to re-use the chain cover index (from Synapse 1.26) when responding to the state_ids endpoint.

That last one turns out to be a pretty big deal: we've seen an order of magnitude improvement in both the CPU and DB cost of the state_ids endpoint. For example, the average CPU usage by that endpoint on matrix.org dropped from few seconds to well under 100ms:

Enjoy. 🙂

This release also includes further improves to our SSO support, including allowing spam checkers to distinguish between new registrations and first-time SSO users and fixing account reactivation when local passwords are disabled. Now that MSC2858: Multiple SSO Identity Providers has passed its Final Comment Period, we've also updated Synapse to respond to the stable versions of endpoints introduced by that MSC.

See the Release Notes for further information.

Python / Platform Deprecations

As a reminder, the next release of Synapse (1.31, scheduled for April 5th) will be the last to support Python 3.5 or PostgreSQL 9.5, both of which have reached their upstream end of life.

We will also cease building packages for Ubuntu 16.04 (Xenial) and Debian 9 (Stretch) at the same time.

Application Service Registration Changes

Note that Application Services must provide a type parameter with the value "m.login.application_service" when calling POST /_matrix/client/r0/register. Synapse currently allows registration without an explicit type, but this divergence from the spec will be resolved in a future release.

Thanks

Synapse is a Free and Open Source Software project, and we'd like to extend our thanks to everyone who contributed to this release, including dklimpel, ShadowJonathan, and tlvb.

Conduit accepted by Prototype Fund

Conduit is a Matrix homeserver written in Rust https://conduit.rs

timokoesters offered:

Hello everyone! I'm excited to announce that Conduit has been accepted by Prototype Fund and will be funded by the Federal Ministry of Education and Research over the next 6 months: https://prototypefund.de/project/conduit/

The focus lies on federation support and overall improvement and stability, maybe we will even land version 1.0 at the end.

I am surprised how Conduit went from a small hobby project to a very promising Matrix server in just a year. Thank you all for accompanying me on this journey, I really appreciate it.

Now what did we actually do in the last two weeks?

• Query signing keys through other servers

• Many state resolution updates

  • Implement /get_missing_events

  • Implement /state_ids

  • Many bugfixes

• Push notifications on mobile

• Fix joining via alias with appservices

• Enable zstd for database compression (3.3GB -> 1.6GB on old db!)

• Rework state storage to be much more optimized (store a few bytes instead of long strings)

• Send proper HOST headers in federation requests (thanks Gabriel!)

Conduit is beginning to run fairly well on the state resolution branch, we will probably merge it after fixing the last few bugs.

This is really excellent news! Congratulations to Timo on this achievement!

matrix-media-repo

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

TravisR reported:

v1.2.5 is out now with several bug fixes and other improvements. The most notable things being:

• Optional support for Sentry (error reporting). This is the same error reporting structure that Synapse uses, so it should fit right in 🙂

• Several oEmbed URL previews have been fixed, making them useful again. Rejoice once again with a preview of Tweets, Giphys, and other rich content.

• Fixed a bug where after uploading media to a datastore the media repo would then download it again before returning it. This made remote media downloads inefficient (it'd download from the remote server, upload to S3, then download from S3, then return it to the user), sorry.

• Sometimes a wobbly database could cause some issues with future requests. While I recommend a not-wobbly database, the media repo should be more resilient to this sort of problem now.

As always, if you have bugs or encounter problems with setup then please pop by #media-repo:t2bot.io

Synapse

callahad told us:

As I mentioned last week, we've been focusing on nailing down some inefficiencies in federation performance. Well, Synapse 1.30.0rc1 is out, and I'm very excited to share one result of that work:

If you look closely, you'll note an order of magnitude improvement in our handling of the /_matrix/federation/v1/state_ids/{roomId} endpoint. On matrix.org, we've seen that endpoint go from averaging a few seconds of CPU time to well under 100ms. Database usage is similarly reduced.

This improvement by @clokep builds on the chain cover index that @erikjohnston implemented in Synapse 1.26.0 to speed up the calculation of auth chain differences during state resolution.

Synapse 1.30 will be released early next week.

We also shipped Sygnal 0.9.0 today, which has a few minor bug fixes as well an initial prototype of Web Push support, per the Hydrogen update in last week's TWiM.

Nio, Mio, wow-io!

Nio is a client written with SwiftUI

helge5 announced:

I ported the native https://nio.chat iPhone client to macOS Big Sur, and call that "Mio". Nio and Mio share the same SwiftUI code base, with the Mio changes being merged into the Nio upstream repository. Like Nio, Mio is still in very early stages but looks quite nice already.

A preliminary build can be downloaded over here: https://zeezide.de/download/Mio.app-0.2.0-2.zip, and I posted a screenshot in the Nio channel: https://matrix-client.matrix.org/_matrix/media/r0/download/matrix.org/RpPiQFJytjXboshcUnqnGwrd.

Some time ago we featured Nio running on an M1 Mac via Catalyst, this is being compiled natively for Mac.

Nheko

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

Nico (@deepbluev7:neko.dev) offered:

Thanks to LorenDB, notifications now omit the reply fallback and show that that message is a reply instead. They also should not break on encrypted rooms anymore (they show that the message was encrypted for now, but they will be decrypted in the future, if that is enabled in the settings). Emotes should now also show up in them properly and if someone sends an unencrypted image, this should show up with a preview in the notification as well.

Jedi18 ported the room switcher, which can be accessed with Ctrl+K to Qml, which fixes a lot of readability issues and should improve how the rooms get filtered.

Jedi18 also fixed a few issues with playing video on Windows. Salahmak made sending media easier by allowing you to send the image by just pressing enter.

Nheko now also stores images outside of the database, which should decrease database size in the future and make it easier to clean out that part of the cache. We also now use native menus where possible and fixed a few crypto and sync issues as well as formatting of mentions sent by Nheko. Nheko should now not randomely fail to /sync anymore, if your network connection dropped out in between. Also the flatpak should now be able to use your webcam in more cases, but this means we also use less sandboxing now. If you don't like that, you can disable access to all devices, but that sadly also includes the webcam.

Quaternion

kitsune reported:

Yet another beta-approximation of Quaternion at version 0.0.95 arrived, with the main change being fonts finally unified throughout the application. Translators are still very much welcome (French is almost there to be marked as "sufficiently complete", e.g.). Expect 0.0.95 release in the nearest weeks.

Synapse

callahad said:

(💭 If this gets published every Friday evening, shouldn't it be Last Week in Matrix?)

On Monday we released Synapse 1.29.0! The most visible highlights are new configuration settings which can limit disclosure of user profile information and optionally rank local users higher when searching the user directory. However, we've also made quite a few tweaks under the hood, including some initial improvements to presence performance and allowing the media repository to regenerate missing thumbnails on demand.

The next release of Synapse will focus on mitigating several known inefficiencies and problematic behaviors around federation performance; I look forward to telling you more about that when it reaches release.

We're also excited to announce that we've secured funding to participate in the next round of Outreachy internships. Outreachy encourages people from underrepresented or nontraditional backgrounds to participate in F/OSS. We have funding for one intern and are proposing two possible projects focused on either modernizing Sygnal/Sydent, or extending Complement so it can replace more of SyTest.

While applications for this round have closed, we also expect to also participate in the end-of-year internship round, applications for which will open in September.

Nheko

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

Nico (@deepbluev7:neko.dev) announced:

This was the week of internal changes. If you are building from source, the following changes may affect you:

• After some distros now ship a newer fork of lmdbxx under the lmdbxx package name, we migrated to that version. While we wanted to do that for some time, if you have been using your distro package and builds now fail for you, you may want to use the bundled version of lmdbxx. Similarly, if there are new database issues, that you experience, please report them!

• Similarly, we dropped our dependency on tweeny, since we only used that in one location and the same thing can be done natively, so you can remove that from your package builds.

• Furthermore we are now stricter with how we validate tls certificates and bumped the minimum version to tls 1.2. If that causes issues for you, please report them as well. There is a known issue, that if you are using the bundled OpenSSL, it may not load your system certificate chain, so you will get TLS errors. We are still trying to find a proper solution for that.

• We also disabled the epoll backend on all ARM builds instead of just our flatpak, since that one just crashes on ARM and until that is fixed in the library we are using, this would lead to a much worse experience on those platforms (and we didn't notice that before, because we disabled it a long time ago in our flatpak while debugging a related issue).

Apart from that, we did also have some cool stuff happening. One thing I want to especially highlight is the push work from tilde. It is one direction that I never thought of Nheko moving in and I think UnifiedPush is a really cool project!

We also switched from inline buttons to a hover overlay for message actions. Please try it out and give us feedback, if that is an improvement or makes the experience worse! It does at least make it clearer, which button belongs to which message, make the interface less messy and scrolling faster.

We also try to suppress the notifications caused by @⁠room mentions, when you reply to such a mention now by inserting a zero width joiner. This seems to work fine for all clients and servers but Element Web... So at least for everyone not using Element Web, if someone replies to an @⁠room as a mod on Nheko, they should not get a notification anymore. (Full disclosure, that was an idea from the FluffyChat team!)

UnifiedPush, what is it, what happened this week, and why should you care?

vurpo announced:

UnifiedPush is an interface that apps can use to receive push notifications without caring about which service transported those push notifications to the device, and it's an interface that you can implement to deliver push notifications to people's apps, if you've come up with a great new way to transport push notifications from the internet to a device (did someone say push over Matrix?).

UnifiedPush has been specified for Android with some apps implementing it for a few months now, but now I've been working on specifying and implementing it for D-Bus platforms. (This is mostly intended for mobile Linux OSes such as postmarketOS, but any platform with D-Bus will work!) This means I've implemented a Gotify-based distributor that runs on Linux, and also implemented UnifiedPush in nheko to give it the capability to receive push notifications. I've yet to iron out all the details, so push in nheko isn't exactly ready to be released yet, but I can demonstrate with a video!

To you, Matrix client developers who desperately want to receive push notifications and get your app woken up while it is not running (on Linux or Android), this means that you should simply implement UnifiedPush in your app to receive pushes from the user's choice of distributor. (note: D-Bus API is not yet in the spec, but under discussion) How? See https://unifiedpush.org and join #unifiedpush:matrix.org to discuss it further!

Dept of Guides 🧭

Discord bridging guide

Cos shared a nice guide to configuring mx-puppet-discord: https://boilingsteam.com/how-to-bridge-discord-in-matrix/.

Soru, the author of mx-puppet-discord, wanted to add some clarifications for the article:

The section on having to set up your .well-known is slightly incorrect: mx-puppet-discord does normal C-S API discovery, so if your C-S API is not on any subdomain it will already just work, .well-known is just needed in case that differs. Additionally, you can set up a manual mapping in your config.yaml (also helpful if you need http for e.g. local development). This is totally unrelated to setmatrixtoken.

While the guide mentions bridges, it does not mention setispublic <puppetId> 1/0 to make the bridge public / private. If you want your relay to just be usable by anyone, you should do setispublic <puppetId> 1, as then the rooms it creates aren't invite-only.

If you have any other questions or need help, please visit #mx-puppet-bridge:sorunome.de , thank you!

Final Thoughts 💭

Brendan Abolivier shared this weeks ago, and we missed it. But, it's really nice content that doesn't go stale.

I did a talk at FOSDEM 2021 two weeks ago titled "Mental health and free software" in which I talk about my experience dealing with mental health issues while working as a full-time Matrix developer and give leads to address some of these issues. I've uploaded the recording of the talk at https://tube.abolivier.bzh/videos/watch/c28a3957-25cb-4519-ad3d-9f8812f88ee2 🙂

See you next week, and be sure to stop by #twim:matrix.org with your updates!

Synapse 1.29.0 is now available!

This release includes several useful new configuration options for administrators of federated home servers. In all cases, the defaults match Synapse's prior behavior.

• AndrewFerr implemented include_profile_data_on_invite and allow_profile_lookup_over_federation which can limit disclosure of your users' profile information. These both default to True.
• We've also implemented user_directory.prefer_local_users which weights users on the same homeserver higher in directory searches. This defaults to False.

Synapse is now easier to run in proxied environments, with tzyl implementing support for the NO_PROXY environment variable, as well as recognizing lowercase variants of that and related proxy variables.

Under the hood, we've been steadily improving our type hints, especially in light of the recent release of Twisted 21.2.0 which includes its own type annotations. We've also landed some improvements which reduce the amount of work Synapse does when presence is enabled and you join a room for the first time. Oh, and the media repository now regenerates missing thumbnails on demand.

Lastly, if you deploy Synapse behind a reverse proxy, Synapse now expects to receive an X-Forwarded-Proto header on incoming requests and will log a warning if it is missing. See the upgrade notes for more information. The full changelog has more information on what's in this release.

Synapse is a Free and Open Source Software project, and we'd like to extend our thanks to everyone who contributed to this release, including aaronraimist, AndrewFerr, dklimpel, ShadowJonathan, and tzyl.

• [MSC3038] Typed typing notifications

Spec Core Team

This week the Spec Core Team worked on MSC2858 (sso ID providers), MSC2403 (knocking) and MSC2746 (voip signalling), as well as held another retrospective of the past month. Discussion mainly focused on process and the new spec redesign. Speaking of which...

New Spec Platform

The new spec has launched! 🎉 Check it out at https://spec.matrix.org/unstable! Release versions will be landing sometime soon. Bear with us as we finalise the new release process.

Huge thanks to wbamberg for working hard on bringing the idea to a reality. The Matrix.org foundation will continue maintenance of the platform and continue to make it even better for developers in the coming months.

We've already got a number of bug reports that need fixing. If you find anything that's a bit off with the redesign, please file an issue at https://github.com/matrix-org/matrix-doc. Thanks!

TravisR told us:

v1.2.3 is out now with a highish priority fix if you have audio thumbnails enabled. Other goodies include an X-Robots-Tag header and some artifact repairs on gif and apng thumbnails. See https://github.com/turt2live/matrix-media-repo/releases/tag/v1.2.3 for the full changelog.

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander said:

Earlier this week we released Dendrite 0.3.11, and since then we have merged a significant number of appservice fixes to master which will go into the next release. With these, bridges should stand a much better chance of working with Dendrite.

Changes include:

• Events are now properly sent to interested appservices

• Appservice namespace exclusivity is now respected properly

• Users starting with _ can now be registered by appservices correctly

• Room alias queries for appservices have been improved and should work now

We also upgraded a number of dependencies.

Spec compliance has improved slightly:

• Client-server APIs: 60%, up from 56% last week

• Server-server APIs: 82%, up from 80% last week

As always, please feel free to join us in #dendrite:matrix.org for general Dendrite chat, and #dendrite-dev:matrix.org if you are interested in contributing!

Spec compliance is really progressing!

Synapse

Synapse is a popular homeserver written in Python.

callahad told us:

We've heard some feedback that Synapse's release cadence—an RC every other week, with releases in between—can feel a bit overwhelming. In response, I'm going to try to write a little less about each RC and instead simply refer to the 1.29.0rc1 Release Notes from yesterday.

We'll shout a bit more when that matures into a formal release early next week. 🙂

On non-release weeks I'll try to spend a little more time focusing on the behind-the-scenes aspects of developing Synapse in our TWiM updates. If there's anything in particular you'd like hear about, let me know!

Speaking of, we're experimenting with using GitHub Discussions for... discussions.

We don't want to go full-on mailing list, but it might be nice to have a place to for slower, asynchronous conversations that don't quite fit into the more rapid pace of a typical Matrix room.

Our first two discussion topics ask about:

• Your experiences with GitHub Discussions

• How Synapse could be better

Please do weigh in!

Dept of Bridges 🌉

GroupMe bridge (matrix-groupme-go)

karmanyaahm offered:

I'm working on a GroupMe bridge I made based on tulir's mautrix-whatsapp and mautrix-go.

I aim to add features like double puppeting, end to bridge encryption, etc over time, but an alpha release is available now. I would love to get bug reports and testing info to fix them.

matrix-appservice-bridge v2.6.0-rc1

Half-Shot announced:

A PSA this time around. Please test this release and update as soon as you can when we go to release on Monday next week. We've included a change to correct how users are registered against the homeserver to comply with the spec (Synapse accepts a /register call without a type=m.login.application, and versions 2.5.0 and below of the matrix-appservice-bridge sent these invalid requests). I'm hoping to eventually retire this behaviour from Synapse, so the more people that upgrade the better!

Also this PR is the Synapse-side change to remove this behaviour. If your appservice implementation uses this behaviour, please chime in.

matrix-appservice-irc hits v0.25.0(-rc1)

Half-Shot told us:

Hey folks, this release contains a bunch of tiny-but-useful bugfixes that you'd hate to miss out on. The full release comes next week but if you want to help us test early, come and get it while it's hot! This release includes the all important fixes from matrix-appservice-bridge v2.6.0-rc1 which fix a spec compliance issue.

Element Web on IPFS

TR_SLimey reported:

I mentioned a while back that I've put Element Web on IPFS.

Since then, I unfortunately had to change its DNSLink domain, so I decided to post about it again, with the new addresses and some minor updates. Here are the former:

• ipns://element-web.0x1a8510f2.space/ (Main DNSLink address)

• ipns://k2k4r8mx8muu913j5oy3e4zvt77xtks8xgxuamlv0ltzwx95lcgk2glw (IPNS hash which the above address points to)

• ipfs://bafybeievxs6qzzbfbn6xcbz3xwxhjzxkffjbpwbcc3gikrac6ytqkkutva (IPFS hash of the current snapshot of the above)

In other news, I've updated Element on IPFS to v1.7.22 and made a tiny script to easily update it in future. In case it's of use to anyone, it's right here:

#!/bin/bash

if [ "$#" -ne 2 ]; then

        echo -e "Invalid number of arguments (got $# but 2 required)!\nUsage: $0 <element web folder> <release tag to download>" >&2
        exit 1

fi

wget -c "https://github.com/vector-im/element-web/releases/download/$2/element-$2.tar.gz" -O - | tar --overwrite --strip-components=1 -xzv -C $1 element-$2

ipfs add -r -p $1

echo "Now use: 'ipfs name publish -key=<publish key> <folder ID>' to publish on IPFS"

Cactus Comments

carl announced:

I am very excited to launch Cactus Comments (https://cactus.chat) today together with @asbjorn:olli.ng!

Cactus Comments is a federated, web-embeddable comment system. And of course, we federate by building on Matrix!

On the frontend - your website - we embed a Matrix client written in Elm that renders Matrix rooms as comment sections. The client is designed to be especially easy to embed on static sites. Once you log in to the client, it will only communicate directly with your Matrix server of choice.

On the backend, an application service is used to create rooms on-demand and help with moderation. It is built with Python and is completely stateless. It does this by modelling all state in native Matrix objects without any custom events!

The entire thing is free and open source software and we would love it if you were to contribute. We really hope some of you will give it a try!

Join our matrix room: #cactus:cactus.chat

Read the introductory blog post: https://cactus.chat/blog/hello-cactus-comments/ Try the demo: https://cactus.chat/demo/

Source code: https://gitlab.com/cactus-comments

What a project! Let's see how we can integrate this with the Matrix.org blog!

Matrix Queue Processor

reivilibre reported:

With things on the Internet vanishing, I've been wanting to start saving copies of interesting web pages and videos to my server-at-home.

This really doesn't involve much more than just running youtube-dl or archivebox on the relevant URLs, but I needed a better way than having to e-mail myself reminders to download things…

I decided to make Matrix Queue Processor.

You can run it occasionally (or set it up to run in a cron job!) and it will then read all outstanding messages and feed the text to a given command, such as youtube-dl.

You can choose for it to delete processed messages, or tick them off (✅). If the command wasn't successful, it will instead reply with the exit code.

It's not particularly sophisticated but it might at least be a small starting point for anyone who wanted to make something similar, and it is end-to-end encryption capable because it uses the Python matrix-nio SDK.

See this example of use with youtube-dl; it fails on the second message because it's not a video page URL:

I like this a lot - there are so many uses for this project.
