Decentralized Systems and Network Services Research Group output

Florian told us:

The article of my research group Decentralized Systems and Network Services Research Group from the KASTEL Institute of Information Security and Dependability and me, Analysis of the Matrix Event Graph Replicated Data Type, was published in the Open Access journal IEEE Access! 📰 🥳 Open Access here means that the article is freely available for you to read, under CC-BY.

In layman's terms, we showed that the Event Graph provides a strong form of eventual consistency even when new events are applied in arbitrary order. In addition, this consistency guarantee can still be provided even if all other servers in a room are malicious, which is unexpected compared to the honest majority required for the usual Distributed Ledger Technology. We also looked at the problem of “If servers randomly select at which parents at the bottom of the Event Graph they append new events, and the number of parents for an event is limited, how can you be sure that the Event Graph does not grow arbitrarily wide?“, which is something that puzzled me since the beginning of my Ph.D. two years ago. It is easy simulate a given setup and see that the width shrinks really fast, but it is also easy to see that arbitrary growth has a likelihood larger than zero. As this was astonishingly hard to grasp mathematically, we were very happy that we could recruit Prof. Dr. Norbert Henze from the Institute of Stochastics as co-author to provide evidence that you can expect the Event Graph to shrink to a normal width quite quickly.

Let me quote parts of the abstract for some more technical details:

[…] By comparison with traditional decentralized communication systems, Matrix replaces pure message passing with a replicated data structure. This data structure, which we extract and call the Matrix Event Graph (MEG), depicts the causal history of messages. We show that this MEG represents an interesting and important replicated data type for decentralized applications that are based on causal histories of publish-subscribe events: First, we prove that the MEG is a Conflict-Free Replicated Data Type for causal histories and, thus, provides Strong Eventual Consistency (SEC). With SEC being among the best known achievable trade-offs in the scope of the well-known CAP theorem, the MEG provides a powerful consistency guarantee while being available during network partition. Second, we discuss the implications of byzantine attackers on the data type’s properties. We note that the MEG, as it does not strive for consensus or strong consistency, can cope with n > f environments with n participants, of which f are byzantine. Furthermore, we analyze scalability: Using Markov chains, we study the number of forward extremities of the MEG over time and observe an almost optimal evolution. […] With the properties shown, a MEG represents a promising element in the set of data structures for decentralized applications, but with distinct trade-offs compared to traditional blockchains and distributed ledger technologies.

Dept of Servers 🏢

Synapse

Synapse is a popular homeserver written in Python.

callahad announced:

Hey, it's Friday!

We released Synapse 1.28 yesterday, with the bulk of effort going into stability improvements and bug fixes, and an emphasis on further improving social login.

We're also working to more clearly communicate our prioritization of issues, starting with documenting our triage and labeling process for the core Synapse repository on GitHub.

(Still very much a work in progress, but starting to shape up nicely.)

We're also on track to maintain our fortnightly cadence of Release Candidates, with 1.29.0rc1 due out in just a few days. I look forward to telling you all about it next week!

Homeserver Deployment 📥️

Kubernetes

Ananace offered:

Another week, another bump of the Kubernetes chart and image of Synapse (to 1.28.0), still haven't had time to fix it to be image agnostic - the Synapse team is just developing far too fast.

Dept of Bridges 🌉

Gitter

Eric Eastwood announced:

We've added a "Chat via Matrix" button next to the join button in a Gitter room so you can jump straight into Matrix and start chatting that way. We've also added a Matrix.to link in the chat header so you can switch off to your favorite Matrix client at any time.

New LINE messenger bridge

fair offered:

matrix-appservice-line: A bridge for LINE messenger based on running LINE's Chrome extension in Puppeteer. Based on tulir 's mautrix-amp, as per Eric Migicovsky's suggestion 🙂

Currently very rough around the edges, but message sending & receiving in 1:1 chats works, as does conversation syncing & backfilling.

Repo: git://miscworks.net/matrix-appservice-line
Discussion: #matrix-appservice-line:miscworks.net

Dept of Clients 📱

Neochat 1.1

Carl Schwan announced:

We released NeoChat 1.1 containing 2 months of new features and bugfixes. Most notably message editing, sticker events support, rewritten login screen, SSO support and more commands. Check it out at https://carlschwan.eu/2021/02/23/neochat-1.1/

In addition to the 1.1 release from earlier, aa13q added support for fancy animation for the 🎆, 🎉 and 🌨️ emojis. This feature can be disabled.

aa13q shared this video too!

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) sent a teaser image first, then added:

As seen from the image, you can now share your screen. This currently only works on X11, since there are no cross platform APIs for that, so look out for that, if you run into issues.

Jedi18 also polished the UX a bit more and fixed bugs, so registration should now work properly again and leaving or joining rooms should place you in the right rooms after that. We also fixed some inconsistencies, where text could be misaligned, when writing long messages.

Quaternion

kitsune reported:

Version 0.0.95 beta4 is out, with significantly better Markdown support (code fences work now, and the overall formatting is better), further improvements to the shuttle dial and other smaller fixes. The release notes and some packages are at their usual place at GitHub; the Flatpak is also coming real-soon-now.

No (or almost no) changes in strings are expected before 0.0.95 from now, so translation contributions are very welcome at Lokalise. German, Polish and Spanish translations are quite advanced but need just a few more entries; the French translation is just about half-way; and there are many prominent languages not even started. You can help!

libQuotient

kitsune reported:

libQuotient 0.6.5 is out, featuring fixes in rich replies handling and the updated Matrix URIs support, as per the latest iteration of MSC2312, enabling shorter, nicer Reddit-style URIs such as matrix:r/thisweekinmatrix:matrix.org.

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 (how many?) weeks we ("tusooa and her longcat," we hope someday we can

remove this annotation :P):

1. Released libkazv 0.1.0 and matrix-tencent-forward-bot 0.1.0.

   Those are stable enough to run as daemon, at least for days.

2. Added related ebuilds to the overlay.

3. Implemented streaming uploads for libkazv.

4. Made matrix-tencent-forward-bot support directly forwarding images

   to the matrix room.

Opsdroid 0.21

Cadair reported:

opsdroid is an easy to use chatops framework with excellent matrix support.

0.21 Release

This week opsdroid 0.21 has been released, it's an incremental release but includes a couple of nice matrix related features and fixes. The highlights are:

• Support authorization by access token in addition to user name and password for the matrix connector. #1707.

• Fix parsing a sync response with more than one message in it. #1715.

• Minor fixes to the matrix documentation. Thanks to @anoadragon453 @xDiesel76 for these.

For a full list of the other changes see the release notes.

If you have any questions or want to get involved come say hi in #opsdroid-general:matrix.org, raise an issue on GitHub and checkout the docs.

Caridina, Crystal library for Matrix

erdnaxeli said:

Caridina, a Crystal library for Matrix, got some new releases, which bring it to v0.10.2. It now supports the last version of Crystal (0.36.1) and redacted events, which I discovered the hard way were making the lib crash. Internally a big part of the lib was rewritten using macros, which makes the code a lot clearer but the API doc too. Thanks to Ruma actually for giving me inspiration about implementing events using macros.

Again, if you like Crystal and want to write some matrix bot, this library might interest you. Feel free to open issues about bugs or feature requests! There is now a room #caridina:cervoi.se to talk about it.

Dept of Bots 🤖

taavi

select announced:

So I had a minute to release my open q&a bot taavi.

I always wanted to write a chatbot that does cool things, so checkmark for that one on the list. In addition to that I recently failed a job interview. For their technical skill test (I did not fail this :P), I got a task for which I learned how to use puppeteer, then saw a post on reddit about Tuxi and together with my previous project that included Matrix (Audius), I knew what I had to do: create Taavi.

I have created this bot as a "weekend project", literally one day for the code and one day for documentation. Surely it's far from perfect but I don't have any big plans with it so far… If you think I should add some features, create an issue and let me know. I could imagine adding other websites / services to it like last.fm, do you have any ideas?

I gave my daughter the task to choose a name for a bot, that can answer any question in the world, and she came up with Taavi, nice!

Not sure if TWIM worthy, but here's a nice article about the recent flood of people migrating away from whatsapp, and why people should've migrated to matrix instead of Signal.

(In German)

There is also a sympathetic response that has been discussed on HN.

Seirdy said:

i've been getting some feedback from other matrix users on a blog post i wrote that outlined a few concerns I had about the Matrix ecosystem and steps for improvement. idk if it'd be relevant in TWIM, but I noticed that "Final Thoughts" sometimes linked blog posts so I thought I'd share: https://seirdy.one/2021/02/23/keeping-platforms-open.html

Synapse 1.28.0 is now available!

This release comes with several further improvements to the user experience of single sign-on and numerous bugfixes and stability improvements.

For admins, Synapse 1.28 adds a new Admin API for retrieving event context and implements new spam checker hooks which enable checking file uploads and remote downloads. We've also improved memory usage of media repository workers.

Lastly, we have marked an undocumented Admin API for deprecation. If any of your tools use /_synapse/admin/v1/users/<user_id> to get account information, please replace that with the V2 List Accounts API, which has been available since Synapse 1.7.0.

There are no special upgrade instructions for 1.28.0. See the full changelog for more details 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 arya2331, auscompgeek, bubu, compu42, dklimpel, dykstranet, and shadowjonathan.

We'd also like to thank yoric for thoroughly reviewing and re-organizing the Synapse CONTRIBUTING.md file.

anoa offered:

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:

• No MSCs were merged this week.

MSCs in Final Comment Period:

• MSC2312: Matrix URI scheme proposal (merge)

New MSCs:

• MSC3015: Room personal name

• MSC3014: HTTP Pushers for the full event with extra rooms information

• MSC3013: Encrypted Push

• MSC3012: Post-registration terms of service API

• MSC3009: Websocket transport for client <--> widget communications

• MSC3008: Scoped access for widgets

• MSC3007: Forced insertion and room blocking by self-banning

• MSC3006: Bot Interactions

Spec Core Team

The Spec Core Team has spent this week working on getting MSC2312 (Matrix URI Scheme) over the line, which is really exciting! Otherwise the team has been reviewing MSC2304 (knocking).

New Spec Platform

Work is currently underway in migrating to the new spec platform. A PR for updating the CI of matrix-org/matrix-doc to build the new spec is up, and an equivalent for matrix-org/matrix.org should be up next week.

MSC3013

sorunome said:

Soru has been working on experimenting with / designing a way to improve push systems within the matrix ecosystem, so that ideally clients can display full event contents in a notification and dispose of specific push notifications without the need for any extra HTTP calls. This lead her to making MSC3013 (encrypted push), so that no gateway is able to read event contents pushed down to the client and MSC3014, so that the client can know which rooms have been read on other devices, allowing them to dispose push notifications.

This is more than just MSCs already, soru already got encrypted push in a patched synapse and a patched fluffychat working locally, and it is working super great!

Dunno soru is just really excited about this somehow >~< 🦊

Dept of Servers 🏢

Hedwig: push gateway

krille reported:

Let's talk more about Hedwig: This is a push gateway for matrix and an alternative to Sygnal. Hedwig is completely written from scratch in Rust (Yes! Rust!) and offers the basic functionality to forward matrix push notifications to Firebase Cloud Messaging. That's it. Nothing more. It is intended to be as lightweight as possible and so it is very fast and stable. Just change a simple config.toml file and run the binary. There are docs for how you can configure a proxy in Apache2 and an example systemD service file. Currently it only supports event_id_only formatted notifications but maybe, in the future, we expand this functionality.

Learn more: https://gitlab.com/famedly/services/hedwig

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander reported:

This week we released Dendrite 0.3.10, and have committed a couple more fixes to master:

• The database is now only queried for remote servers once in /send

• The oldest cache entries are now gradually evicted, saving a small amount of memory

• The destination queues in the federation sender are now not stored forever, saving some memory

• A bug where a non-excluded event could be accidentally excluded from /sync has been fixed

• Some dependency fixes have been merged

Sytest compliance:

• Client-server APIs: 60%

• Server-server APIs: 82%

As always, feel free to join us in #dendrite:matrix.org for general Dendrite chat or #dendrite-dev:matrix.org for development discussion.

Synapse

Synapse is a popular homeserver written in Python.

callahad reported:

Synapse 1.27 is out, and you can read all about it on the Matrix Blog! This is the version that powered FOSDEM, and we're super proud of it. Especially the much improved support for multiple social login providers, which debuted at FOSDEM and is now enabled on matrix.org.

In addition to all the performance, stability, and social login improvements, there are two important things to note:

1. If you use SSO, you will need update your configuration before upgrading; please see the link above for details.
2. We were unable to build Docker images for ARM platforms in time for this release, and will not build images for ARMv7 in future releases.

• To avoid unexpected breakage, we have not updated the latest tag on Docker Hub for this release; if you want Synapse 1.27, you'll need to specifically reference the v1.27.0 tag.

• Images for ARM64 (and an updated latest tag) will return with the next Synapse release.

It took us a bit longer than usual to get 1.27 out the door, so we're also pleased to announce that 1.28.0rc1 is also now available, and we expect to release it early next week. Keep your eyes peeled for more on that next week!

Homeserver Deployment 📥️

Kubernetes

Ananace announced:

New chart versions have been pushed for Element 1.7.21 and Synapse 1.27.0.

The rejiggering to allow arbitrary images for the Kubernetes chart got delayed due to lack of time, but 1.27.0 should hopefully be the last version with that limitation.

Dept of Clients 📱

Nio

Nio is a client written with SwiftUI

kilian offered:

Nio has seen some great improvements since the last update, mostly thanks to gaining a new main contributor \o/

• History loading now works (seems like a rather essential messenger feature 😄)

• New conversations can be started (with a slick UI)

• There's a preliminary (but well-working!) build for macOS on Catalyst

• As a first step towards E2EE support Nio can now participate in encrypted sessions while running

• Many new translations (thanks to all the contributors on translate.element.io!)

• Lots of additional bugfixes and improvements

Join us in #niochat:matrix.org for more details 😊

FluffyChat

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

krille said:

FluffyChat 0.27.0 is out. Not with the new design but with some minor design improvements like the return of the presence list top bar (or whatever you would name it!). Also this release brings a lot of bug fixes, working bootstrapping and the switch to our new Push Gateway (in Rust) we have invented inside of Famedly. You can find it here: https://gitlab.com/famedly/services/hedwig

FluffyChat on Pinephone

Lukas Lihotzki said:

FluffyChat runs on the PinePhone (Flutter Linux ARM64). I've built it with flutter master on the PinePhone itself, because cross-compiling is not yet supported. Currently, Flutter Linux on the PinePhone only works with X11. It crashes with Wayland.

I am on the brink of buying one of these!

Nheko

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 (@deepbluev7:neko.dev) told us:

We had a fun week this time. Today I tested trilenes screen sharing code, which seems to work pretty well on X11, although it only shares the full screen atm. I expect window sharing to land next week though. We also ran into some issues with matrix.org enabling optional SSO login, which locked some people out of their accounts, since Nheko preferred SSO login in that case... This is now fixed and in such cases you will be offered both login flows.

Jedi18 also added a room name completer, which means you can finally complete aliases when typing them! The room settings were also ported to Qml and now actually show the room topic. Apart from that there were various UX fixes here ad there, like hovering actually working properly now, emote messages formatting correctly in notifications and more. We also adapted the matrix: uri support to the latest changes, although the MSC is a bit volatile atm, so it may need some more adaptions over time.

I think that's all, have a nice weekend everyone!

Hydrogen

Bruno announced:

I'm back working on Hydrogen, and started to tackle logging to be able to diagnose problems better. I've opted for a structured log format in JSON that gives a tree of log nodes for an entire operation (e.g. sync, or sending a message, ...) which will be more compact and should also be easier to find patterns in than a pure line based format. I had hoped to get that out in a release by today but didn't get as far as I hoped, so should get released early next week.

Yes! Hydrogen progresses!

Element

Neil told us:

Delight

• Social Login

  • Social log-in has shipped to matrix.org, we are seeing about 40% of new users opting for a social method. Next up will be landing some robustness improvements as well as automatic avatar import.

• Spaces

  • We are aiming to get a basic version up and ready over the next few weeks. The idea is to have something behind a labs flag that will work for Spaces containing public rooms only. After that we will think about more complex cases such as Spaces containing private rooms.

VoIP

• Fix for crash on Android caused by VoIP tiles

• Design updates on iOS for in-call view and dial pad

• Couple of tweaks to web that may help 1:1 call connectivity

Web

• Element 1.7.21 was released on Monday (15 Feb)

iOS

• Element 1.2.1 was released on Friday (12 Feb)

• We now use XcodeGen to generate Xcode project files. Please check new instructions to build the project. It is only on develop for the moment

• We made an update to libolm so that it accepts an external pickle key to encrypt its data when serialising it. Element-iOS uses the Keychain to provide this key.

• We started to review and merge pending PRs in our repos but we still have work. Thanks for your contributions and patience

Android

• We are preparing the release 1.1.0 which contains the work on VoIP

• This release will also contain a lot of bug fixes

synadm is growing! Pull requests have been submitted, issues been raised, bugs fixed and quite some user community seems to have evolved around it as it’s regularly mentioned on #synapse:matrix.org

Since it’s first announcement on TWIM in December, notable things happening in the project are:

• Massive internal overhaul, tidying up and refactoring

• Media Admin API support

• Make Room Admin API support

• Delete Group (community) API support

• 4 available output formats (json, yaml, pprint, human)

• Python requests debugging switch

• Textual Error responses of Synapse now showing in output

• Licensed under GPL-3

Have a look at the latest release notes for a complete list of new features and fixes: https://github.com/JOJ0/synadm/releases

Thanks a lot to contributors @hpd, @kaiyou, @schwindp, @aaronraimist and @rht! Keep those PR's and ideas coming! You have been a great help!

Next features on the roadmap are "Purge History API", regular matrix client calls support and login as a user. Help me prioritise features by raising an issue: https://github.com/JOJ0/synadm

Still, I am basically a one man show, and certainly any contributions are warmly welcomed! Even as a non-programmer you can help by keeping the implementation-status list up to date. If you find an admin API missing, please take a minute and use the integrated edit functionality github provides and add it to the list: https://github.com/JOJ0/synadm#implementation-status--commands-list. It helps contributors to quickly find out what feature they could code!

I am also thinking about finding people who'd like to join the team, code new features and help maintain codebase, review PR's, get push access and so on. Spread the word! Join #synadm:peek-a-boo.at!

Final Thoughts 💭

Nico (@deepbluev7:neko.dev) offered:

Oh, and maybe as a side note: Since Steam voice chat failed me one too many times now, I now use Nheko for voice chat, if I just play with one other player. It is more reliable and most people I play with do have a voip capable Matrix client installed!

Synapse 1.27.0 is now available!

We're especially proud of this release, as this is the version of Synapse that powered FOSDEM 2021 on Matrix. As such, our main focus was on stability, performance, and long-awaited support for social login.

What's New

To our surprise, nearly half of all people who created accounts on the FOSDEM homeserver did so via a social login method. Full support for those methods is included in Synapse 1.27.0, and already available for all users on the matrix.org homeserver.

We've also changed how we use Redis in larger deployments, making Synapse more resilient to lost connections and eliminating delays when restarting with multiple federation senders.

Our Server Admin APIs saw a few tweaks, including new APIs to query and delete forward extremities or list the current state of a room.

See the full changelog for more.

Breaking Changes for SSO

If you use Single Sign-On (SSO) via SAML, OAuth2, or OpenID Connect you must adjust your provider's configuration before upgrading to Synapse 1.27.0, as some endpoint URLs have changed. See the upgrading notes for more information.

Dropping ARMv7 Docker Images

We were unable to produce ARM-based Docker images for this release due to problems with cross-compilation. As a result, we have made the difficult decision to cease building 32-bit ARMv7 Docker images as part of our release process. We will resume publishing ARM64 images with the next Synapse release.

Users on ARMv7 platforms (most notably Raspberry Pis) should consider building images locally using Synapse's Dockerfile or switching to installing Synapse directly as a Python module. Users with Raspberry Pi 3's or newer also have the option of installing a 64-bit Linux distribution and using an ARM64 Docker image.

Thank you to our contributors

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, intelfx, jcgruenhage, Oliver-Hanikel, rht, and y-pankaj.

Hi all,

Just over a week ago we had the honour of using Matrix to host FOSDEM: the world's largest free & open source software conference. It's taken us a little while to write up the experience given we had to recover and catch up on business as usual... but better late than never, here's an overview of what it takes to run a ~30K attendee conference on Matrix!

[confetti and firework easter-eggs explode over the closing keynote of FOSDEM 2021]

First of all, a quick (re)introduction to Matrix for any newcomers: Matrix is an open source project which defines an open standard protocol for decentralised communication. The global Matrix network makes up at least 28M Matrix IDs spread over around 60K servers. For FOSDEM, we set up a fosdem.org server to host newcomers, provided by Element Matrix Services (EMS) - Element being the startup formed by the Matrix core team to help fund Matrix development.

The most unique thing about Matrix is that conversations get replicated across all servers whose users are present in the conversation, so there's never a single point of control or failure for a conversation (much as git repositories get replicated between all contributors). And so hosting FOSDEM in Matrix meant that everyone already on Matrix (including users bridged to Matrix from IRC, XMPP, Slack, Discord etc) could attend directly - in addition to users signing up for the first time on the FOSDEM server. Therefore the chat around FOSDEM 2021 now exists for posterity on all the Matrix servers whose users who participated; and we hope that the fosdem.org server will hang around for the benefit of all the newcomers for the foreseeable so they don't lose their accounts!

Talking of which: the vital stats of the weekend were as follows:

• We saw almost 30K local users on the FOSDEM server + 4K remote users from elsewhere in Matrix.
• There were 24,826 guests (read-only invisible users) on the FOSDEM server.
• There were 8,060 distinct users actively joined to the public FOSDEM rooms...
• ...of which 3,827 registered on the FOSDEM server. (This is a bit of an eye-opener: over 50% of the actively participating attendees for FOSDEM were already on Matrix!)
• These numbers don't count users who were viewing the livestreams directly, but only those who were attending via Matrix.

Given last year's FOSDEM had roughly 8,500 in-person attendees at the Université libre de Bruxelles, this feels like a pretty good outcome :)

Graphwise, local user activity on the FOSDEM server looked like this:

How was it built?

There were four main components on the Matrix side:

1. A horizontally-scalable Matrix server deployment (Synapse hosted in EMS)
2. A Jitsi cluster for the video conferencing, used to host all the Q&A sessions, hallway sessions, stands, and other adhoc video conferences
3. An elastically scalable Jibri cluster used to livestream the Jitsi conferences both to the official FOSDEM livestreams and to provide a local preview of the conference on Matrix (to avoid the Jitsis getting overloaded with folks who just want to view)
4. conference-bot - a Matrix bot which orchestrated the overall conference on Matrix, written from scratch for FOSDEM by TravisR, consuming the schedule from FOSDEM and maintaining all the necessary rooms with the correct permissions, widgets, invites, etc.

Architecturally, it looked like this:

On the clientside, we made heavy use of widgets: the ability to embed arbitrary web content as iframes into Matrix chatrooms. (Widgets currently exist as a set of proposals for the Matrix spec, which have been preemptively implemented in Element.)

For instance, the conference-bot created Matrix rooms for all the FOSDEM devrooms with a predefined widget for viewing the official FOSDEM livestream for that room, pointing at the appropriate HLS stream at stream.fosdem.org - which looked like this:

Each devroom also had a schedule widget available on the righthand side, visualising the schedule of that room - huge thanks to Hato and Steffen and folks at Nordeck for putting this together at the last minute; it enormously helped navigate the devrooms (and even had a live countdown to help you track where you were at in the schedule!)

Each devroom was also available via IRC on Freenode via a dedicated bridge (#fosdem-...) and via XMPP.

The bot also created rooms for each and every talk at FOSDEM (all 666 of them), as the space where the speaker and host could hang out in advance; watch the talk together, and then broadcast the Q&A session. At the end of the talk slot, the bot then transformed the talk room into a 'hallway' for the talk, and advertised it to the audience in the devroom, so folks could pose follow-on questions to the speaker as so often happens in real life at FOSDEM. The speaker's view of the talk rooms looked like this:

On the right-hand side you can see a "scoreboard" - a simple widget which tracked which messages in the devroom had been most upvoted, to help select questions for the Q&A session. On the left-hand side you can see a hybrid Jitsi/livestream widget used to coordinate between the speaker & host. By default, the widget showed the local livestream of the video call - if you clicked 'join conference' you'd join the Jitsi itself. This stopped view-only users from overloading the Jitsi once the room became public.

The widgets themselves were hosted by the bot (you can see them at https://github.com/matrix-org/conference-bot/tree/main/web). Meanwhile the chat.fosdem.org webclient itself ended up being identical to mainline Element Web 1.7.19, other than FOSDEM branding and being configured to hook the 'video call' button up to the hybrid Jitsi/livestream widget rather than a plain Jitsi.

Meanwhile, for conferencing we hosted an off-the-shelf Jitsi cluster sized to ~100 concurrent conferences, and for the Jibri livestreaming we set up an elastic scalable cluster using AWS Auto Scaling Groups. Jibri is essentially a Chromium which views the Jitsi webapp, running in a headless X server whose framebuffer and ALSA audio is hooked up to an ffmpeg process which livestreams to the appropriate destination - so we chose to run a separate VM for every concurrent livestream to keep them isolated from each other. The Jibri ffmpegs compressed the livestream to RTMP and relayed it to our nginx, which in turn relayed it to FOSDEM's livestreaming infrastructure for use in the official stream, as well as relaying it back to the local video preview in the Matrix livestream/video widget.

Here's a screengrab of the Jitsi/Jibri Grafana dashboard during the first day of the conference, showing 46 concurrent conferences in action, with 25 spare jibris in the scaling group cluster ready for action if needed :)

There was also an explosion of changes to Element itself to try to make things go as smoothly as possible. Probably the most important one was implementing Social Login - giving single-click registration for attendees who were happy to piggyback on existing identity providers (GitHub, GitLab, Google, Apple and Facebook) rather then signing up natively in Matrix:

This was a real epic to get together (and is also an important part of achieving parity between Gitter and Element) - and seems to have been surprisingly successful for FOSDEM. Almost 50% of users who signed up on the FOSDEM server did so via social login! We should also be turning it on for the matrix.org server this week.

Finally, on the Matrix server side, we ran a cluster of synapse worker processes (1 federation inbound, reader and sender, 1 pusher, 1 initial sync worker, 10 synchrotrons, 1 event persister, 1 event creator, 4 general purpose client readers, 1 typing worker and 1 user directory) within Kubernetes on EMS. These were hooked up for horizontal scalability as follows:

The sort of traffic we saw (from day 2) looked like this:

How did it go?

Overall, people seem to have had a good time. Some folks have even been kind enough to call it the best online event they've been to :) This probably reflects the fact that FOSDEM rocks no matter what - and that Matrix is an inherently social medium, built by and for open source communities (after all, the whole Matrix ecosystem is developed over Matrix!). Also, Matrix being an open network means that folks could join from all over, so the social dynamics already present in Matrix spilled over into FOSDEM - and we even saw a bunch of people spin up their own servers to participate; literally sharing the hosting responsibility themselves. Finally, having critical infrastructure rooms available such as #beerevent:fosdem.org, #cafe:fosdem.org and #food-trucks:fosdem.org probably helped as well.

That said, we did have some production incidents which impacted the event. The most serious one was on Saturday morning, where it transpired that some of the endpoints hosted on the main Synapse process were taking way more CPU than we'd anticipated - most importantly the /groups endpoints which handle traffic relating to communities (the legacy way of defining groups of rooms in Matrix). One of the last things we'd done to prepare for the conference on Friday night was to create a +fosdem:fosdem.org community which spanned all 1000 public rooms in the conference, as well as add the +staff:fosdem.org community to all of those rooms - and unfortunately we didn't anticipate how popular these would be. As a result we had to do some emergency rebalancing of endpoints, spinning up new workers and reconfiguring the loadbalancer to relieve load off the main process.

Ironically the Matrix server was largely working okay during this timeframe, given event-sending no longer passes through the main process - but the most serious impact was that the conference bot was unable to boot due to hitting a wide range of endpoints on startup as it syncs with the conference, some of which were timing out. This in turn impacted widgets, which had been hosted by the bot for convenience, meaning that the Jitsi conferences for stands and talk Q&A were unavailable (even though the Jitsi/Jibri cluster was fine). This was solved by lunchtime on Saturday: we are really sorry for folks whose Q&As or conferences got caught in this. On the plus side, we spotted that many affected rooms just added their own widgets for their own Jitsis or BBBs to continue with minimal distraction - effectively manually taking over from the bot.

The other main incident was briefly first thing on Sunday morning, where two Jibri livestreams ended up trying to broadcast video to the same RTMP URL (potentially due to a race when rapidly removing and re-adding the jitsi/livestream widget for one of the stands). This caused a cascading failure which briefly impacted all RTMP streams, but was solved within about 30 minutes. We also had a more minor problem with the active speaker recognition malfunctioning in Jitsi on Sunday (apparently a risk when using SCTP rather than Websockets as a transport within Jitsi) - this was solved around lunchtime. Again, we're really sorry if you were impacted by this. We've learned a lot from the experience, and if we end up doing this again we will make sure these failure modes don't repeat!

Other things we'd change if we have the chance to do it again include:

• Providing a to-the-second countdown via a widget in the talk room so the speaker & host can see precisely when they're going 'live' in the devroom (and when precisely they're going to be cut in favour of the next talk)
• Providing a scratch-pad of some kind in the talk room so the host & speaker can track which questions they want to answer, and which they've already answered
• Keep the questions scoreboard and scratchpad visible to the speaker/host after their Q&A has finished so they can keep answering the questions in the per-talk room, and advertise the per-talk room more effectively.
• Use Spaces rather than Communities to group the rooms together and automatically provide a structured room directory! (Like this!)
• Use threads (once they land!) to help structure conversations in the devroom (perhaps these could even replace the hallway rooms?)
• Make the schedule widgets easier to find, and have more of them around the place
• Make room directory easier to find.
• Give the option of recording the video in the per-talk and stands for posterity
• Provide more tools to stands to help organise demos etc.

So, there you have it. We hope that this shows that it's possible to host successful large-scale conferences on Matrix using an entirely open source stack, and we hope that other events will be inspired to go online via Matrix! We should give a big shout out to HOPE, who independently trailblazed running conferences on Matrix last year and inspired us to make FOSDEM work.

If you want to know more, we also did a talk about FOSDEM-on-Matrix in this month's Open Tech Will Save Us meetup and the Building Massive Virtual Communities on Matrix talk at FOSDEM went into more detail too. Our historical Taking FOSDEM online via Matrix blog has been somewhat overtaken by events but gives further context still.

Finally, huge thanks to FOSDEM for letting Matrix host the social side of the conference. This was a big bet, starting from scratch with our offer to help back in September, and we hope it paid off. Also, thanks to all the folks at Element who bust a gut to pull it together - and to the FOSDEM organisers, who were a real pleasure to work with.

Let's hope that FOSDEM 2022 will be back in person at ULB - but whatever happens, the infrastructure we built this year will be available if ever needed in future.

Famedly in the media

Nico (@deepbluev7:neko.dev) announced:

Famedly (Matrix based application for German hospitals and clinics) seems to be getting positive feedback so far: https://medtech-zwo.de/aktuelles/nachrichten/nachrichten/famedly-ueberzeugt-mit-messenger-dienst-im-krankenhaus.html

Article in German, but my favourite parts are:

• They used the word "Anti-Datenkrake" to describe how data is handled in the application, which basically is a metaphor for Famedly being the opposite of the usual corporations trying to pry their tentacles into everyones personal data. See also: https://en.wiktionary.org/wiki/datenkraken

• They actually use [matrix]–Protokoll to refer to the Matrix protocol. The open and standardized Matrix protocol seems to be a big selling factor.

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

Merged MSCs:

• No MSCs were merged this week.

MSCs in Final Comment Period:

• No MSCs are in FCP.

New MSCs:

• MSC3005: Streaming Federation Events

• MSC2998: Room Version 7

• MSC2997: Add t-shirt

Spec Core Team

Some chatter about the MSC2403 (knocking) as FCP has been proposed. Otherwise work on MSC1772 (Spaces) as that nears production and some encryption work with MSC2874 (single SSSS).

The team is carefully debilitating MSC2997, which spurred out of a conversation during FOSDEM2021. What sizes to include? What font to use? What colour do we paint this bike shed? All incredibly complex questions.

New Spec Platform

Will Bamberg has done an incredible job with getting both an entire redesign and an internal refactoring to the Matrix Spec. Remaining work includes ironing out some remaining minor blockers (https://github.com/matrix-org/matrix-doc/pull/3002, https://github.com/matrix-org/matrix-doc/pull/3003), merging changelog representation with respect to the current idea of a global Matrix Spec version number (https://github.com/matrix-org/matrix-doc/pull/2992) and then finally hooking up all the CI/CD to deploy it all (my job!).

We're planning to present the new spec on a new domain; running it in parallel with the old design for a bit before eventually retiring the latter.

Dept of Servers 🏢

CONSTRUCT

grin shared this note from Jason:

This week in Matrix Construct added Application Services support. I've been using the Mautrix Telegram bridge on a daily basis, and it's been a pleasure to develop with. Expect more bridges to be tested in the coming weeks. I'll also be working on completing the documentation for how to setup a bridge in Construct. Just to give some insight: The server has the ability to manage all of your bridges as sub-processes. In any client, just create a room for your bridge and enter its configuration there. Voila! The bridge's console appears right in that room and can even highlight you about errors!

Join us at #construct:zemos.net to learn more about bridges and lend a hand.

Synapse

Synapse is a popular homeserver written in Python.

callahad announced:

We survived FOSDEM! Last week was relatively slower in Synapse land as we paused to catch our breath, but we do have news!

First, releases. Synapse 1.27.0rc2 is out now (changelog), and we anticipate a full 1.27 release early next week. This is basically the branch that FOSDEM ran, so we think it's a good one.

Second, keeping with our biweekly development cadence, the first 1.28 release candidate is due out midweek next week, so keep your eyes peeled for that. Given FOSDEM, most of our recent focus has been on stability, bug fixes, and social login. We hope to knock your socks off with more ambitious features soon. 😉

Homeserver Deployment 📥️

YunoHost

Pierre told us:

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

Synapse integration had been updated to 1.25.0 (1.26.0 available in branch testing)

Element Web integration had been updated to 1.7.16 (1.7.20 available in branch testing)

Dept of Clients 📱

SchildiChat Web/Desktop

qg offered:

SchildiChat is a fork of Element, which focuses on UI changes such as message bubbles and a unified chat list for both direct messages and groups, which is a more familiar approach to users of other popular instant messengers.

Thanks to @michi7801 we can now provide builds for macOS!! 🍎

Code on GitHub: https://github.com/SchildiChat/schildichat-desktop

Matrix room: #schildichat-web:matrix.org

Nheko

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 (@deepbluev7:neko.dev) announced:

We just landed basic support for edits. Which means edits are now applied to the original message instead of showing the fallback and you can edit your messages. You can also change a text message to a video (or the other way around) or change, who you replied to, but the latter fails to render in some clients properly, so be aware of that. Edits also send a secondary relation format, which makes handling edits easier, but I still haven't written up the MSC for that... The UI is not final yet and you can't show edit history yet, but apart from that it may or may not work fine.

There were also a lot of bugfixes like broken kerning in some cases, improved focus handling when clicking buttons in the timeline, Duplex devices should now work in calls, notifications now work on Haiku and a few more.

Now please stop asking for edits! :D

Cos discovers the /addwidget command in Element Web

Cos offered:

Public service announcement: Widgets are awesome. You can use /addwidget <url> in Element Web to add any web page in a iframe to the sidebar of Element Web. They get default name "Custom Widget" but you can rename them from /devtools menu. Very useful for group calendars, status pages and other info related to Matrix rooms.

Element

Neil announced:

Delight

• Social Login

  • We’ve concluded most of the development on Social Login, and tested it last weekend on the FOSDEM deployments. We found that over 50% of new accounts used it to register! We’ll be deploying Social Login to matrix.org in the near future after polishing some final pieces on iOS.

• Spaces

  • We’re iterating on the user experience for Spaces, first focusing on setting up, sharing and joining public spaces.

VoIP

• VoIP branches merged to develop on iOS and & Android - please test voice & video calling if you have the android develop build, or testflight for iOS will be coming soon. More complex scenarios with multiple devices are particularly useful to test, eg. do other devices stop ringing when you answer on a different one?

Web

• 1.7.21-rc.1 is now available at https://staging.element.io, including:

  • Fixed screen sharing in VoIP calls

  • Added window vs. full screen sharing option in VoIP calls

  • Fixed event permalinks to show link text instead of a room pill

• 1.7.21 planned for release on Monday (15 Feb)

• Element Desktop nightly builds are now using Electron 11

  • Please report any issues you notice so we can address them before the next Element release

iOS

• 1.2.1 has been submitted to Apple. TestFlight should be available from tomorrow:

  • All new VoIP stuff described above

  • Handle User-Interactive Authentication for delete device and adding user 3pid.

  • Improve grace period management and setup Cross-Signing after login if possible when using SSO.

• XcodeGen integration into the Element-iOS codebase is almost complete. From next week, we will not have merge conflicts on the pbxproj files. This also means better control on build settings.

Android

• Initial sync work improvements: performance is far better regarding RAM usage and stability (especially true for large accounts), though duration is still a concern.

• Started working on running integration tests via CI.

• 1.0.17 released, fixing a join over federation bug. Expect 1.0.18 next week.

Dept of SDKs and Frameworks 🧰

Ruma

Ruma is a set of Rust library crates around Matrix

jplatte offered:

In the last two weeks,

• @DevinR528 fixed the push rule precedence for iterating a Ruleset

• @jsparber added an unstable workaround for Synapse sometimes requiring authentication in the profile API (the spec says no authentication is required)

• @NerdyPepper added an event_type accessor to our event enums

• @NerdyPepper added support for m.room.message events with custom msgtypes

Dept of Ops 🛠

matrix-docker-ansible-deploy

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

Slavi told us:

Thanks to @Peetz0r, matrix-docker-ansible-deploy can now install a bunch of tools for monitoring your Matrix server: the Prometheus time-series database server, the Prometheus node-exporter host metrics exporter, and the Grafana web UI.

To install these services, follow our Enabling metrics and graphs (Prometheus, Grafana) for your Matrix server docs page.

Dept of Interesting Projects 🛰️

SpaceHub

MTRNord offered:

This is a super early announcement.

As now Spaces exist and are kind of testable if you know how I went ahead to plan organizing my 200 rooms I currently have into spaces and realized soon that I will have A LOT of nested Spaces.

So I am now starting to write a tool to generate these spaces easily from a folder structure and exporting them.

You may ask why not a yaml or json format: Simply to more easily allow forking of existing collections. A folder structure is much easier to do a diff over in git than file content.

Feel free to join #space-hub:nordgedanken.dev for discussions or have an eye on https://github.com/matrix-spaces-generator where at the time of writing this only an example of the spaces folder structure exists.

Keymaker

MTRNord reported:

Small update time:

We are currently starting to add some documentation to it over at https://docs.joinmatrix.rocks/users/what-is-keymaker.html

It at time of writing still very barebones but over the next few weeks the goal is to add the Code of Conduct as well as a server admin guide on how to use this.

FOSDEM 2021

FOSDEM is happening this year, regardless of pandemics or anything else! Actually FOSDEM in my experience is a huge super-spreader event even in normal years, so it may be refreshing to know that this year it will be fully virtual, and hosted using Matrix and Jitsi!

Matrix have several relevant talks happening:

• Adding Matrix for interoperability to existing chat apps Saturday @ 10:25 (this is about Gitter bridging/integration)
• Pinecones and Dendrites - P2P Matrix Progress Saturday @ 11:30 (this is about P2P)
• Building massive virtual communities in Matrix Sunday @ 12:00 (this is about Spaces)

Plus, there is a bonus talk from Brendan:

• Mental health and free software Sunday @ 13:50 (in which Brendan talks about mental health issues in the context of working on free software, which may or may not relate to people, though certainly not me, pinging him at all hours to ask about customer integrations and features)

Plus, perhaps the most important part of FOSDEM: FOSDEM 2021 Matrix T-Shirt (Limited Edition) is now available

Federation Tester

Neil Alexander told us:

federationtester.matrix.org has been updated today so that it now works properly with servers running TLS 1.3!

Conduit

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

timokoesters told us:

We're coming closer to correct federation every day! Currently we are reviewing and improving Devin R's MR and looking for mistakes, we will be giving it a try soon.

Meanwhile I worked on:

• Push rule settings, making it finally possible to mute rooms

• Appservice compatibility, I'm currently trying to get the mautrix-hangouts bridge to work

• Optimizations, incremental sync in big rooms (rooms with >3k members) went from 1.3s to 13 ms, (100x improvement)

Thanks to Famedly and everyone who supports me on Liberapay or Bitcoin!

Synapse

Synapse is a popular homeserver written in Python.

callahad said:

FOSDEM is tomorrow! We're all very excited to be powering the fosdem.org homeserver, and we hope you'll join in over the weekend.

Earlier this week we released Synapse 1.27.0rc1, though the final release is currently blocked on resolving a regression in Synapse 1.26 (#9264) which could cause logins to fail if your public_baseurl was unset in your Synapse configuration. The workaround is to ensure that value is correctly set for your deployment.

Otherwise, we're quite excited to get 1.27 out the door, as it:

• Solves an issue (#9172) where federation senders could take many minutes to catch up after restarts.

• Contains countless improvements to our support for social login methods, many of which will be live for FOSDEM users this weekend.

We've also included the usual host of bug fixes and Admin API additions, but more on those when the actual release happens. You can preview the release notes on GitHub.

See you at FOSDEM!

Dept of Bridges 🌉

mautrix-imessage

Tulir announced:

My iMessage bridge is starting to be usable now. Text and files work in both directions and tapbacks and replies work iMessage->Matrix. Currently it only supports running on a Mac, the iOS option will come later. The bridge doesn't require opening ports to the Mac, it uses a simple proxy that turns the usual HTTP appservice transactions into a websocket instead.

The bridge itself can be found at https://github.com/tulir/mautrix-imessage and the websocket proxy is at https://github.com/tulir/mautrix-wsproxy. The Matrix room is #imessage:maunium.net

mautrix-signal

Tulir told us:

I made the first release for mautrix-signal. No particular reason, but it's v0.1.0 now. Recent changes include:

• Better profile syncing (Signal profile names should sync when restarting)

• Support for Signal profile avatars

• Support for bridging stickers from Signal

Gitter

Eric Eastwood said:

FOSDEM is happening this weekend! Come see our FOSDEM talk in the Real Time Communications track on Saturday around how we made Gitter speak Matrix and how you can add Matrix support to your own app: https://fosdem.org/2021/schedule/event/matrix_gitter/

*--

We're also working on MSC2716 to support backfilling the massive archive of historical messages on Gitter over on Matrix. We're prototyping the MSC on Synapse and have a suite of Complement tests to verify that the homeserver implementation is working according to the specification.

The DAG visualization (made with TARDIS) shows that we're inserting messages 1-3 between A and B:

matrix-appservice-irc reaches 0.24.0-rc1

Half-Shot said:

Another release! Wow. We're also testing 0.24.0-rc1 which has quite a few big ticket items this week. Off the top of the list is a new command to !plumb rooms dynamically in admin rooms, provided you have permissions in the bridge (happy days self hosters!). We've also added the feature to warn if your messages don't get through in your admin room. Finally, there are a bunch of small bug fixes and one large one that should make the bridge much more resistant to netsplits, so that it should recover in a much safer way should it get hit by a ton of traffic. Please test, and if all goes well the formal release will be out next week!

https://github.com/matrix-org/matrix-appservice-irc/releases/tag/0.24.0-rc1

matrix-appservice-slack hits 1.7.0-rc1

Half-Shot announced:

Happy friday bridge users! Today we're releasing 1.7.0-rc1 of the Slack bridge which contains some more critical encryption fixes for our experimental encrypted rooms support. We've also fixed a few serious bugs where DMs would not be persisted to the database in some cases. Please test, and let us know how you get on!

Syphon updated

ereio said:

It's been a little over 6 months since I've posted an update for Syphon in TWIM, but a lot has changed since then! There

have been several releases since and a lot of groundwork to get the client further out of Alpha. We've also had people start to contribute in various ways, including with PRs, and I can't thank people enough for all their hard work and support.

Big thanks to TR_SLimey whose contributions went out in this release! All that said, I'll try to give updates here more often.

Version 0.1.6 was just released this week and includes:

New Features:

• SSO Login & Signup

• Reactions / Emoji Support 🎉

• View Edited Messages (Condensed)

• Swipe To Reply

• Cross Server Room/Topic Search

• Forgot / Reset Password Flow

Performance

• More caching and cold storage saving/loading improvements

• Parsing all matrix data from separate threads

Bug Fixes

• fixed e2ee decryption issue - cache related

• fixed read receipt bugs

• fixed various caching performance issues

• fixed failed syncing on most self-hosted homeservers

• fixed settings permanence issues

• fixed new direct chat with invalid user_ids

Since it's been a while, if anyone has any feedback, questions, or concerns, feel free to chat in the #syphon:matrix.org room, message me @ereio:matrix.org, or email me at [email protected].

If you'd like to help out with the project in any way, just ask. We'd love to have your support 😃

Nheko

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

red_sky☄️ offered:

Nheko now has an optional privacy screen! The timeline will optionally blur when the nheko window loses focus. The timeout for when the blur effect should be applied is configurable in a number of seconds between 0 and 3600 (1 hour).

Nico (@deepbluev7:neko.dev) added:

Cheers, some update probably mentioned it already, but FOSDEM is near. Make sure to check out the Matrix stand! RedSky and I (Nico) will probably be there at some random times as well as other cool people from the Matrix-verse! We even made a small promo video about Nheko!

In other news, lorendb extended the drop zone for media to the full timeline, the privacy screen got merged, some more emojis should now display properly, you can now change your avatar and displayname globally or per room and clicking a matrix link in your browser should now actually open the link in Nheko (we were missing the %u in the .desktop file).

That's all, see you at FOSDEM!

Frost

fabian offered:

I have been learning about matrix the last few months. The result of that is frost a very basic GUI matrix client written in Go using Gio and a CS library. Highlights of the project so far are:

• Works on Linux, Windows, macOS and Android (although I only test on Linux and often break the other platforms)

• Should work on WASM and iOS with not too much effort

• Very, very limited E2EE support. (If the session is manually verified by other clients, events can be encrypted and decrypted.

• Library that handles storage, encryption and some other things with a opinionated but simple to use (I hope) interface.

I started this project to understand matrix and improve my Go skills (which are not that great) and if somebody wants to play around with it and give me some feedback on it, I would very much appreciate it. Meet me in #frost-dev:intothecyber.space

Fractal

Alexandre Franke reported:

Former GSoC intern and long time Fractal contributor Julian Sparber started on Monday working full time on Fractal thanks to a grant from NlNet. He is funded for the next six months and we’re looking forward to all the amazing work he will do. You can read more details on his blog.

and then, Alexandre Franke reappeared:

Apart from that grant, we’ve done a fair chunk of work since the previous piece of news two months ago. Here are the highlights:

• We kept refactoring. Some examples merge requests are 647, 673, 674, 680, 684 and 686.

• We upgraded our secret-service dependency to 2.0

• HTML rendering has landed!

Don’t believe me? Well, go try out our nightly flatpak build!

Konheko

Nico (@deepbluev7:neko.dev) said:

I've updated my Sailfish client to the API changes in the latest Sailfish early access release. You will need to install the new version on Sailfish 4.0.1.45, since some private APIs got removed. No functional changes though (I hope).

NeoChat

Carl Schwan reported:

NeoChat is continuing to make progress. First of all Tobias, Nicolas and Hannah have been working on packaging NeoChat for many platforms. We now have nightly builds for Android, Windows, macOS, AppImages and Flatpak. There is still work to be done to improve the quality of the builds and fixing some platform incompatibility bugs. Nicolas has also been working on optimizing the performance and the RAM usage, fixing a few bottlenecks. Tobias finally landed his big revamp of the login flow and we now support login using single sign-on. Myself (Carl) worked on E2EE support in NeoChat and Quotient. This week we finished our Qt bindings for libOlm and started adding device key tracking and more!

Dept of Interesting Projects 🛰️

MatrixFS

Ananace told us:

Since there was talk about it, I went through and updated / cleaned up the MatrixFS code a bit; Got it working with tail -f (and probably other applications that poll based on mtime/size changes), added a GC that drops unaccessed data from memory after a while, and reduced the communication overhead slightly

Matrix in the News 📰

Element Android: interesting times

Element Android had a fun time last weekend, getting temporarily removed from the Play Store. Google were somewhat responsive in getting it back up though, and overall Matrix received a nice boost of attention from the tech press as a result!

Gizmodo, ArsTechnica, Engadget, Next INpact, Android Police and Protocol all posted sympathetic coverage of the situation.

Dept of Sadness ☹️

Daydream

MTRNord said:

After a long time of no message from it I am officially ending that project.

Dept of Servers 🏢

Synapse

Synapse is a popular homeserver written in Python.

callahad announced:

One week 'til FOSDEM!

In addition to several talks specifically about Matrix, Synapse's own Brendan Abolivier will be speaking in the Community devroom on Mental health and free software: What I wish I’d been told before I got into free software, and more. Check it out!

We're also excited to announce Synapse 1.26.0's release! As mentioned last week, the two biggest new features are a faster algorithm for state resolution and initial support for enabling multiple OpenID Connect providers. Additionally, we've sped up redaction in large rooms and made it possible to run more APIs on workers. See the full changelog for details.

We expect to publish a release candidate for 1.27.0 early next week, but we're trying to be conservative about large changes ahead of FOSDEM, so knocking — which is coming! — will have to wait until 1.28.0... 🚪

Dendrite 0.3.8

Dendrite 0.3.8 was released this week! Simple changelog this time:

A well-known lookup regression in version 0.3.7 has been fixed

Homeserver Deployment 📥️

Kubernetes

Ananace announced:

Just released the 1.26.0 version of the K8s-optimized image and chart.

(Not sure how this message will do though, been down the last few days for a database upgrade)

Success: the message did great!

Dept of Bridges 🌉

matrix-appservice-bridge arrives at 2.5.0-rc1

Half-Shot announced:

Hey folks! It's been a while since we've had an update but things are always manic at bridge HQ. This release is a bit of a whopper containing quite a few bugfixes (including improvements to the experimental encrypted bridge support). We've also updated to Typescript 4.1 which is a bit stricter on those promise return types. Finally, you can now create intents on the bridge and use it's components without starting the HTTP listener which has been a longstanding issue for as long as I've been maintaining.

So go out there and test this release, all going well we should 🚢 early next week!

If only you knew what else this guy was working on. More to be shared soon-ish. I hope!

Dept of Clients 📱

FluffyChat

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

krille said:

FluffyChat 0.26.1 has been released today with updated translations, support for Unified Push (https://github.com/UnifiedPush/) and some bug fixes. The Linux Desktop version is fully functional again and the app is much more stable than ever now. We are working hard to bring FluffyChat to the official iOS AppStore next week! :-)

I reinstalled Fluffychat this week as I attempted to support some less-technically-minded friends, and was VERY impressed. If you've tried FluffyChat in the past but missed recent versions I suggest you have another go.

Nheko

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 (@deepbluev7:neko.dev) said:

On Wednesday we released version 0.8.1 of Nheko! It's mostly a bugfix release of 0.8.0, but it does bring some new features here and there:

[0.8.1] -- 2021-01-27

Features

• /plain and /md commands to override the current markdown setting. (contributed by lorendb)

• Allow persistent hiding of rooms with a specific tag (or from a community) via a context menu.

• Allow open media messages in an external program immediately. (contributed by rnhmjoj)

Improvements

• Use async dbus connection for notifications. (contributed by lorendb)

• Update Hungarian translations. (contributed by maxigaz)

• Update Finnish translations. (contributed by Priit)

• Update Malayalam translations. (contributed by vachan-maker)

• Update Dutch translations. (contributed by Glael)

• Store splitter size across restarts.

• Add a border around the completer. (contributed by lorendb)

• Request keys for messages with unknown message indices (once per restart, when they are shown).

• Move the database location to XDG_DATA_DIR. (contributed by rnhmjoj)

• Reload the timeline after key backup import.

• Autoclose completer on space, when there are no matches.

• Make completer only react, when the mouse cursor is moved.

Bugfixes

• Fix unhandled exception, when a device has no keys.

• Fix some cmake warnings regarding GNUInstallDirs.

• Fix tags being broken. If you have no tags showing up, you may want to logout and login again.

• Fix versionOk being called on the wrong thread. (contributed by Jedi18)

• Fix font tags showing up in media message filenames.

• Fix user profile in dark themes showing the wrong colors. (contributed by lorendb)

• Fix emoji category switching on old Qt versions. (contributed by lorendb)

• Fix old messages being replayed after a limited timeline.

• Fix empty secrets being returned from the wallet breaking verification.

• Make matrix link chat invites create a direct chat.

• Fix focus handling on room change or reply button clicks.

• Fix username completion deleting the character before it.

Flathub and other repo updates may take a bit, but in the mean time you can try building it yourself or one of our provided stable downloads. Thank you for all the feedback so far and I'm glad a lot of people seem to be enjoying it so far! All the feedback, bugfixes and issues you provided certainly will help improving Nheko for everyone!

Then, later...

Apart from the current releases, we have a few things cooking right now:

Edits

Yes, I have tried to avoid them for long, but I am finally working on it. It's a bit different to how Element and others do it, but it also generates a fallback to be compatible with the current MSCs where possible. I've grown a bit tired of having to explain myself everytime, why I did not want to support edits (yet), so I'm experimenting with a few solutions now. Expect a blog post summarizing those experiments in the future and maybe an MSC.

Polish

Jedi18 and LorenDB are both busy polishing up the rough corners in Nheko, like finally being able to set your username and avatar in the UI as well as being able to copy text via right click, jdenticons and other fancy stuff. We also had a few contributions in the last release, which should improve the UX a lot.

GSoC

Furthermore we will be participating in GSoC (if matrix.org gets accepted) and will probably mentor a student, that implements a few of the smaller features, which users may be missing after using Element for long.

I think that is all I wanted to share. I hope you enjoy the release and if you have any issues or feature requests, tell us in #nheko:nheko.im or open an issue on Github!

Quaternion

kitsune announced:

Since the project is already fairly rich in features, I decided that it's timely (some would say - way overdue) to bump up the version a bit. In that light, the next Quaternion beta is numbered 0.0.95 beta 3 (no four-number version any more) and it's out now! Release notes list notable changes since (0.0.9.5) beta 2, with two most significant being ability to enter messages in Markdown and the overhauled timeline that allows you to easily discern between already read and yet unread messages and also quickly scroll to the read marker.

Element

Neil reported on behalf of the teams:

Delight

• Social Login

  • Final polishing and bug hunting across all platforms. We are targeting 5 options to begin with (Gitlab, Github, Facebook, Google and Apple) and will hopefully be ready to start setting these up on homeservers next week.

• Spaces

  • Lots of polishing on Element web, you can get all the latest in the matrix live demo session next week!

VoIP

• Added some debugging to web to help debug call connectivity failures

• Fixed a compatibility regression in web with voip v0 clients (ie. element android / ios) - d’oh!

• Android: work on getting call audio routing correct on various different devices

• Design coming up to speed to support on implementation and ongoing UI improvements

• iOS on holiday

Web

• Off cycle 1.7.18 release for VoIP compat bug

• Various tweaks to prepare for FOSDEM

• Element Web 1.7.19-rc.1 is now available at https://staging.element.io, including:

  • Allowed guest users to see widgets

  • Standardised security terminology to reduce confusion

  • Added ability to pin widgets for everyone in the room

iOS

• We made several iterations since the last App Store release (1.1.3) but Element-iOS 1.1.6 is now in the store.

• We made some improvements to use less RAM in the background sync module that manages push notifications.

• We continued to improve performance in E2EE to speed up message sending using pre-sharing keys and re-sharing keys methods. Element-iOS now automatically rejects share requests from not verified devices. It does not send anymore such requests if it is not verified.

Android

• We are working on improving the initial /sync management. The first objective is to reduce RAM usage. Then, we will improve the time to display the room list.

Dept of SDKs and Frameworks 🧰

Ruma

Ruma is a set of Rust library crates around Matrix

jplatte told us:

In the last two weeks,

• @gnieto fixed a small issue in ruma-federation-api

• @tilosp added a convenience constructor for markdown formatted messages

• @NerdyPepper added a definition for the new default push rule .m.rule.reaction from MSC2677 and set up a default Content-Type for requests

Also, @jamtwister imported a bunch of endpoints from @florianjacob's synadminctl into synapse-admin-api.

State Resolution

It's been a really long time since an update on ruma/state-res but work has continued!

• Thanks to a push from @gnieto the state-res crate no longer has its own PDU type, we are now using a trait.

Conduit continues its use of state-res, which has helped workout the kinks and buggy bits.

Dept of Interesting Projects 🛰️

Keymaker

MTRNord told us:

Just a small dev update on things that currently happen over at the Serverlist project "Keymaker" and its companion bot.

Follow it in detail at #serverlist:nordgedanken.dev or https://github.com/keymaker-mx/

• The registration bot finally is starting to get its admin backend -> The registration probably happens in a few weeks from now

• Keymaker has now a admin login page (using matrix as auth provider) to allow a web UI for admins to manage servers (WIP)

• The bot successfully writes servers upon registration to the database. This is the main task of the bot besides the capability to administrate the page using the page

• The bot now is able to be used by admins in an admin room which also gets notifications if a user registered a new server.

Matrix in the News 📰

Beeper has continued to make headlines, and is now being reported around the world:

Andy announced:

Beeper was mentioned in one of the two biggest argentinian newspapers! 😮🙌 https://www.lanacion.com.ar/tecnologia/todo-en-uno-este-es-beeper-el-chat-universal-que-promete-usar-whatsapp-signal-y-telegram-en-un-solo-nid22012021/

There was a pause, as we wondered how the other biggest Argentinian newspaper would react, and it was worth the wait! Andy soon announced:

And now the other biggest newspaper of Argentina wrote an article about Beeper (Matrix is mentioned about half-through the article)!

https://www.clarin.com/tecnologia/beeper-app-mensajeria-unifica-chats-whatsapp-telegram-signal-instagram_0_1bX5iXnxw.html

Anything that goes in Argentina is sure to make waves in Poland, and so it was that Polish media picked up on the story.

TR_SLimey reported:

Beeper has made it to Polish media too, guys :P

https://spidersweb.pl/2021/01/beeper-imessage-na-androidzie.html

The title: "A new multi-messaging platform has arrived. It's creators will send you an old iPhone so you can even use iMessage"

Final Thoughts 💭

Discussing the sharing of code and ideas with Tobias from NeoChat, Nico (@deepbluev7:neko.dev) said:

There really is no stealing, it's more helping each other out and improving things for everyone, users and developers alike. We are not corporations competing, we are one free software community :3

Which I thought was very astute, and decided to include here.

It's FOSDEM next weekend, and we are manically preparing for it. Should be a good one!

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

Synapse 1.26.0 is now available!

Note: This release includes a new database schema version. If you need to roll back to Synapse 1.25.0, you will also need to follow the associated database downgrade instructions.

In addition to a truckload of refactoring and general improvements, Synapse 1.26.0 includes three major new features:

1. A brand new algorithm for calculating the auth chain difference, which should dramatically improve worst case performance during state resolution (#8622).
2. Initial support for enabling multiple OpenID Connect providers, paving the way for proper multi-provider social login workflows.
3. A significant speed-up to redaction performance in large rooms.

It also brings several improvements to Admin APIs:

• Specific media items can be protected from quarantine.
• The joined_rooms API now works for remote users.
• Deactivating a user can now optionally remove their avatar URL and display name.

We've also made it possible to offload several additional APIs to worker processes, including read receipts and account data persistence, further improving Synapse's scalability.

See the full changelog for more.

Lastly, a reminder: we have deprecated Python 3.5 and PostgreSQL 9.5 and will cease support at the end of March. Due to deprecations in our Python tooling, we were unable to produce a binary package for Ubuntu 16.04 LTS (Xenial) in time for this release. We have resolved this for 1.27.

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 0xflotus, chris-ruecker, dklimpel, emelie-qis, jerinjtitus, and tzyl.

Matrix Live 🎙

Dept of Status of Matrix 🌡️

Beeper launched

Eric Migicovsky announced:

NovaChat is now

Beeper

• New website! beeperhq.com. Beeper is a Matrix server+client combo preconfigured with 12+ bridges. Our mission is to bring a lot of new users into the Matrix ecosystem and give them a fast and powerful client to message people on all networks. Beeper is a paid subscription service, but since all the bridges are open source, you can set the whole system up yourself for free if you choose

• We're doing a lot of work to boost bridge reliability. Beeper now comes with bridges to Signal, Whatsapp, FB, Slack, Skype, Telegram, Instagram, Hangouts, Twitter, Discord. iMessage coming within a week or two.

• Sneak peek below of our upcoming desktop UI

Looking for contract work?

• We are offering bounties of $500-2,000 USD to build new open source bridges based on tulir's mautrix-python or mautrix-go libraries. In particular, we would love to commission Linkedin, MS Teams, Google Chat, GroupMe, WeChat, Snapchat (maybe run it in Anbox?), Line and Email (gmail specifically) bridges.

• We are also looking for contract iOS and Android developers familiar with the Element codebase to reskin the app with our new UI. Part-time roles with potential for full time.

• If you're interested, please send me a DM @eric:beeperhq.com

GSOC 2021

Google Summer of Code has come around again! Last year was really successful for Matrix: six projects, with members of the community coming forward to mentor students for their project. This year there is a slight tweak to the formula: the projects will now be 175 hours, rather than the traditional 350, over the summer.

Since we need to submit an application to Google within the next few weeks, I have a request: if you admin a Matrix-related Open Source project and would like to have a student work with you over the summer, get involved!

How to do this:

• Read Google's own documentation on the setup. This is fairly thorough, and should get you most of the way there.

• Think about a task, that you consider a student should be able to contribute to your project over a 10-week/175-hour period. Try to come up with 2-3 of these.

  • It should be a well-defined feature that genuinely contributes to the progress of your project, but maybe doesn't block other work on the critical path.
  • This is a very important step, and one that may need some time and discussion.

• DM me (@benpa:bpulse.org) and we'll talk about next steps.

Dept of Spec 📜

kitsune (aka "fox-avatar guy") reported:

Matrix URI scheme proposal has FCP proposed now - if any of you, the readers of this, have anything to say about it that wasn't said in the past 2 years, speak soon or forever hold your peace. (Ok, you're allowed to write a separate MSC if you come late with revelations.)

This has been an labour of love for kitsune, kudos on his perseverance!

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

Merged MSCs:

• MSC2844: Global version number for the whole spec

MSCs in Final Comment Period:

• No MSCs are in FCP.

New MSCs:

• MSC2974: Widgets: Capabilities re-exchange
• MSC2970: Remove pusher path requirement

Spec Core Team

We've decided to ditch the focus as it was clear that it wasn't a great indicator of progress. Once one team member has reviewed all of the focus items, they will move on to other MSCs. None of that work is reflected in the focus, and items in there often stick around while waiting on a small number of people to complete work on.

As such, we'd instead like to direct people to the Spec Core Team Backlog board, which is a better representation of the current state of things. And of course the weekly list of MSCs state changes above.

Dept of Servers 🏢

Dendrite / gomatrixserverlib

Dendrite is a next-generation homeserver written in Go

Neil Alexander told us:

At the beginning of this week we released Dendrite 0.3.6, which included a number of refactors in the sync API and a selection of fixes. It is also the first version to be released with multi-arch Docker images with ARMv7/ARM64 targets.

Since then, the following changes have been merged:

• Sync filtering support for event types, senders as well as better-supported limits

• Federation support for MSC2946 (Spaces Summary)

• Fixed a bug where large well-known files could consume a lot of memory

• Support for in-process DNS caching for federation traffic (although it is disabled by default)

• Some preparatory work for tracking the most recent membership states in the sync API for future history visibility work

If you are running a Dendrite server, it is highly recommended that you upgrade to the latest version!

Spec compliance is at:

• Client-server APIs: 60%, up from 58% last week

• Server-server APIs: 83%, same as last week

Synapse

🎉 Synapse 1.26.0rc1 is here!

☠️ But don't install it yet; wait for rc2.

A few issues were reported with rc1 (#9187, #9193, #9208), and we'll issue an rc2 early next week once we're confident they've been resolved.

Otherwise, once 1.26.0 is released you can look forward to a new algorithm for calculating auth chain difference in v2 State Resolution which should significantly speed up some of the most expensive state resolution calculations (#8622).

We've also dramatically improved the performance of redactions in large rooms, helping Synapse's moderation tools scale to communities of any size (#9022). And speaking of scaling, Synapse 1.26 makes it possible to offload many different APIs to worker processes, including read receipts and account data persistence.

Lastly, Synapse 1.26 will include support for multiple Single Sign-On Identity providers, though we expect further fit-and-finish for that feature to land in 1.27.

You can preview the changelog and upgrade notes now, but remember: wait for rc2! 😉

mautrix-facebook

Tulir said:

The switch to acting as a mobile app I mentioned last week has been merged and it's starting to be clear that it works better. So far logging in has worked fine for everyone at least after enabling 2FA.

Changes this week mostly included tons of bugfixes (thanks to everyone who already updated and found the bugs) and re-adding some old features like read receipt bridging. The SQLite migration script now exists too. Upgrade instructions can be found at https://github.com/tulir/mautrix-facebook/wiki/Upgrading-to-v0.2.0

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) told us:

Cheers everyone! On Wednesday we released version 0.8.0 of Nheko! The changelog is far too long, because so many people contributed (and it has been a while since the last release), so I'll just put some highlights here!

Highlights

• Voice and Video Calls (contributed by trilene)

  • Call your friends right from within Nheko.

  • Use your camera if you want them to see your face!

  • This requires a somewhat new gstreamer, so our builds don't support it on all platforms yet.

• Cross-Signing and Device/User Verification (contributed by Chethan)

  • Verify who you are talking to!

  • Ensure no malicious people eavesdrop on you!

  • Enable your connected devices to access key backup and your friends to see, which of your devices you trust!

  • Show devices in a users profile.

• Separate profiles (contributed by lorendb)

  • Run multiple Nheko instances with separate profiles side by side.
  • Use multiple accounts at the same time in separate windows.

Features

• Before a call select which audio device to use. (contributed by trilene)

• Auto request unknown keys from your own devices.

• Add a command to clear the timeline and reload it. (/clear-timeline).

• Add a command to rotate the outbound megolm session. (/rotate-megolm-session).

• React to messages instead of replying with arbitrary strings using /react.

• Inline emoji and user completers. (contributed by Lurkki)

• Show filename on hover over an image. (contributed by kamathmanu)

• Mobile mode, that disables text selection and changes some dialogs.

• Allow sending text after a /shrug command. (contributed by MayeulC)

• Allow selecting a ringtone. (contributed by trilene)

• View avatars fullscreen. (contributed by kamathmanu)

• Request or download cross signing secrets in the settings.

• Support 'matrix:' URIs. This works in app on all platforms and on Linux Nheko may be opened by clicking a 'matrix:' link.

• Support inline replies on notifications on Linux.

Packaging is currently in progress, but it will probably take a bit. In the mean time you can download the release from here: https://github.com/Nheko-Reborn/nheko/releases/tag/v0.8.0

Please tell us, what you think and report bugs as you find them! And thanks again to all the contributors! It was a great pleasure to work with you and you really made an impact!

Over and out, the Nheko team!

Adrien added:

Nheko 0.8.0 was in Debian before TWIM.

❤️ for the packagers!

fluffychat 0.25.0

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

krille said:

fluffychat 0.25.0 is out with a lot of bug fixes, improvements, minor design tweaks and a new 3 column layout. iOS will skip this release until we can bring it to the AppStore next week or so

Element for Nextcloud

Gary Kim said:

Element for Nextcloud v0.6.19 has now been released. The new update contains fixes for Single sign-on users, the ability for admins to easily show or hide the labs settings, and an update to Element Web v1.7.17.

P.S. This will be the last version to support Nextcloud 17 and 18 if you're still on those versions.

Element Web instance on IPFS

TR_SLimey announced:

I've set up an Element Web instance on IPFS, which means that now, not even Matrix client downloads can be blocked - censorship resistance at its finest :P

It can be found at:

• ipns://h.an-atom-in.space

or

• ipns://k2k4r8mx8muu913j5oy3e4zvt77xtks8xgxuamlv0ltzwx95lcgk2glw

Element Clients

Updates supplied by the Teams

Web

• Various widget related improvements
• Changed guest access to uniformly only allow read access for now
• Improved CI runtime when testing PRs

iOS

The release we built last week has been blocked due to push notifications issues. We are still on the case On the e2ee side, we have been working on an optimisation for the key re-share mechanism

caridina, Crystal library

erdnaxeli reported:

Today a present you a Matrix client library I've been working for the last few months: caridina.

It is a Crystal library. Currently for reading it implements the sync API and supports the events to do text messaging (all state events + m.room.message). For writing it provides methods to send messages, edit them, and send receipts and typing notifications.

While I would not recommend this library to write a full featured client, it is enough to write a simple text bot. I currently use it for some of my own projects. The README provides some examples of how to use the library.

Feel free to try it, report bugs, ask for missing features if you need them or even contribute!

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.

Features

(Copying from readme:)

• Logging in

• Receiving room states

• Receiving room messages

• Receiving account data

• Receiving presence

• Sending messages

• Send room state events

• Create rooms

• Room invites

• Join rooms

• Typing notifications

• Receipts and fully-read markers

• Leaving and forgetting rooms

• Content repository

• Send-to-device messages

• E2EE (send and receive events only)

What goes here?

This week we ("tusooa and her longcat," we hope someday we can remove this annotation :P)

implemented sending and receiving encrypted events in rooms. Check a demo video below:

opsdroid

opsdroid is an easy to use chat-ops framework with excellent Matrix support.

0.20 Release

This week opsdroid released version 0.20. This is a massive release that's been a long time coming because of a complete rewrite of the internals of the matrix connector to use matrix-nio---thanks to @awesome-michael for the initial work on this.

Having ported the connector to nio, our GSOC student @Tyagdit got to work polishing the nio port and reimplementing the matrix database module in the core opsdroid library. Opsdroid has a concept of memory which is a key-value store which can be backed my many different kinds of databases. The matrix database stores the opsdroid memory in room state, meaning your bot's database and messages are all stored in the same place.

Finally, the other big feature added to the matrix support in this release is End to End Encryption support. Thanks to using matrix-nio as our matrix library it was possible to implement support for encrypted matrix rooms. This also includes support in the matrix database for encrypted memory which works by referencing event ids in room state (see here for more info). As this is the first release to support E2EE I would still consider it "beta"; please open issues if you have any trouble using it.

Highlights

• End to End Encryption support in the Matrix connector.

• Matrix database now included in core, with e2ee support.

• Use of Python's install "extras" to allow for installations with fewer packages.

• Improved documentation of the matrix connector and database (at least a little).

• Support for Python 3.9 (and dropped support for 3.6).

Checkout the full release notes for all the gory details.

If you have any questions or want to get involved come say hi in #opsdroid:matrix.org, raise an issue on GitHub and checkout the docs.

trixnity (kotlin) progress

Benedict said:

A little sneak peek from trixnity, a crossplatform Matrix SDK. Currently I have some issues with ktor, which breaks my serialization.

quotient

kitsune reported:

libQuotient has initiated transition from LGPL 2.1 to LGPL 3 as its distribution license. This is partially driven by the fact that newer Qt is (mostly) distributed under LGPL 3 so the "combined work" (legalese for libQuotient including and linked with specific Qt pieces) would be covered by LGPL 3 anyway. Boring, right?

kitsune added:

Those looking at my contributions to Quotient might have noticed the change of the primary committer's name. Don't fret, this is still me, I just shed the pseudonym (and those who've seen the interview knew my real name already).

Watch "the interview" here, where we discuss (then) progress on MSC2312 (mentioned earlier), and plenty more.

Matrix Corporal

matrix-corporal manages your Matrix server according to a configuration policy

Slavi reported:

Version 2.0 of matrix-corporal has been released.

It's a huge release bringing many improvements (read all of it in the release notes).

Here's a short summary:

• an Event Hooks system has been introduced, so matrix-corporal can now also act like a "generic firewall" (similar to what mxgwd was doing)

• device-free login is now used when impersonating users (thanks to a new API introduced by Synapse v1.24.0) - this is both faster and more resilient.

• support for Interactive Authentication (and thus, End-to-End-Encryption) has been added. Users can now set up E2EE keys, manage devices, etc. (actions that require Interactive Authentication and were previously broken). Requires cooperation between matrix-corporal and the REST auth password provider module.

• End-to-End-Encryption control. matrix-corporal can enforce whether rooms that users create are encrypted or unencrypted. You can force-disable or force-enable encryption for locally-created rooms.

• fixes user-creation regression that happened with Synapse v1.24.0. matrix-corporal v1.12.0 is also out, with a backport of this fix (for users who don't want to jump to 2.0 yet).

Matrix Notepad

KB1RD reported:

• It's not dead! yet

• There's been some code refactoring on the algorithm. Mainly, the search tree used has been split into a different package

• I'm working on porting the Notepad to the new widget API. Ongoing work is on the nextgen branch and is tracked by this project. The widget is currently blocked on some stuff in the widget API, so I probably won't be releasing soon. The code in there needs a ton refactoring, too.

• This means that the old notepad client will disappear on the next release and you'll need to add a widget for the Notepad for any documents that you want to edit. Currently, this means you would have to use Element, but I heard Ditto just might be doing some widget work

• The widget API is planned to do everything and more that my "mxapps" project was supposed to do, so that project will be deprecated in favor of using the widget API

• There's also a little demo/teaser video showing the old notepad talking to the new one. You can see the rate limiting issues that the Notepad hits there, which is on my todo list.

Dept of Guides 🧭

Superb documentation from TU Dresden, as they roll out their deployment

Marvin Dropp said:

doc.matrix.tu-dresden.de

We set up a bilingual (de, en) documentation for all of our university members, to help them get in touch with our matrix instance easily. This documentation is rich on screenshots, simple explanations and will be improved continuously.

Also we mirroring the documentation to GitHub to provide access of our sources to everyone.

(https://github.com/matrix-tu-dresden-de/Dokumentation)

We would appreciate to add further institutions of higher education with own matrix instances to our list.

Viva la federation!

Christian Bruchatz shared some additional context about their deployment growth:

Watch Matrix Live (at the top) this week for a chat with Marvin and Christian.

sorunome offered:

today is the four year m.anniversary of the @sorunome:sorunome.de account! 🎉

Some interesting reads of the last few days:

• Twitter's Bluesky project released a whitepaper comparing various chat/social protocols, rather a detached take but interesting to read
• Jay Graber (arcalinea) published a new post discussing decentralised moderation, which is a serious question for Matrix

Cos announced:

btw i forgot to TWIM that there was once again long Matrix article in Finnish computer culture paper magazine Skrolli. December issue.
