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!

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!

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 noticable 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:

Doing:

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 possiblility 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

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

Homeserver Deployment 📥️

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)

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.

2021-04-09-jvbbb-image.png

<@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.

Slavi offered:

Thanks to Aaron Raimist (Aaron), matrix-docker-ansible-deploy can now install and configure the Mjolnir moderation tool (bot).

Additional details are available in our Setting up Mjolnir documentation.

Chemnitzer Linux Days talk

Benedict said:

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.

Synapse 1.31.0 released

2021-04-06 — Releases — Dan Callahan

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.

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.

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.

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!

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).

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!

nheko1

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

nheko2

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

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

Synapse 1.30.1 released

2021-03-26 — Releases, Security — Dan Callahan

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.

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:

2021-03-26-stateids-again.png

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

TravisR announced:

v1.2.6 is out now with a guest account patch and some added libraries to the Docker image. It's a small one, but worth the upgrade when there's a few spare cycles to use :)

As always, if you run into problems or have questions, visit #media-repo:t2bot.io

Homeserver Deployment 📥️

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

We're working on bridging DM conversations between Matrix and Gitter. For our first iteration, you will be able to start a DM conversation with a Gitter user from Matrix. In the next iteration, we will allow Gitter users to start a DM conversation with a Matrix user.

The following is a small taste of what it will look like and will also be included in the upcoming Matrix live demo day.

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 said:

Hydrogen 0.1.40 got released this week with support for push notifications (look to enable it from the settings) and some other smaller fixes.

(Note that because of a sygnal bug, push messages are sometimes failing to be delivered to mobile. This will be fixed in the coming days without any action needed if you already enable it before.)

If you want to know more about Hydrogen's new shiny notifications, check out this week's Matrix live (at the top of this post)!

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.

Dept of SDKs and Frameworks 🧰

libkazv (and the Kazv Project)

tusooa offered:

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. Recorded state events in timeline. https://lily.kazv.moe/kazv/libkazv/-/merge_requests/2

  2. Added support for streaming download. https://lily.kazv.moe/kazv/libkazv/-/merge_requests/3

Ruby

Ananace offered:

Just pushed version 2.3.0 of the Matrix Ruby SDK, headline features include; Ruby 3.0 support (though might still be a few niggles in there, expect a 2.3.1 once it's been more tested), a complete redesign of the room data cache to improve memory usage and code quality, and general request additions that people were interested in.

Guile-Deck

a_v_p said:

Hello everybody! I released Guile-Deck 0.1.0, GNU Guile SDK for Matrix network: https://lists.gnu.org/archive/html/guile-user/2021-03/msg00048.html

This library allows to write Matrix clients in Scheme Lisp.

Dept of Bots 🤖

Matrix Daily Calendar

uhoreg offered:

I've written a simple little script that connects to CalDav servers and sends me a summary of the events for the day over Matrix. https://gitlab.com/uhoreg/matrix_daily_calendar I find it useful as I don't have enough meetings that I'm constantly checking my calendar, so having a message at the beginning of the day helps me remember the meetings that I do have.

Dept of Built on Matrix 🏗️

🌵 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.

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

krazykirby99999's guide to creating Matrix bots

krazykirby99999 shared with us their guide for creating simple Matrix bots in Python: https://www.reddit.com/r/matrixdotorg/comments/mdqitp/how_to_create_a_matrix_bot/

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!

Synapse 1.30.0 released

2021-03-22 — Releases — Dan Callahan

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:

CPU usage graph

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.
