This Week in Matrix

🔗Matrix Live

🔗Dept of Spec 📜

Andrew Morgan (anoa) says

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

New MSCs:

• MSC3919: Matrix Message Format (IETF/MIMI)
• MSC3918: Matrix Message Transport (IETF/MIMI)
• MSC3917: Cryptographically Constrained Room Membership
• MSC3916: Authentication for media
• MSC3915: Owner power level

MSCs in Final Comment Period:

• MSC3743: Standardized error response for unknown endpoints (merge)

Merged MSCs:

• MSC3905: Application services should only be interested in local users

Closed MSCs:

• MSC2821: Testing Pushers
• MSC3510: Let users kick/ban/demote each other
  • Superseded by MSC3915: Owner power level

🔗Spec Updates

MSC3917: Cryptographically Constrained Room Membership is rather interesting. It aims to make room membership in a room cryptographically verifiable via a "Master Signing Key" that's controlled by users. This is in addition to the homeserver signatures typically placed on events in Matrix. The purpose is to prevent a homeserver from being able to lie about your membership in a room. While not the end-all-be-all solution to this particular problem, it's certainly a well-reasoned take.

🔗Matrix @ IETF 115

This last week (well, last few months), the Spec Core Team has been working on defining Matrix as the standard for interoperable messaging at the IETF level, under MIMI. The current drafts can be found in these places:

• Matrix as a transport for MIMI: https://turt2live.github.io/ietf-mimi-matrix-transport/draft-ralston-mimi-matrix-transport.html (MSC3918)
• Matrix as a message format for MIMI: https://turt2live.github.io/ietf-mimi-matrix-message-format/draft-ralston-mimi-matrix-message-format.html (MSC3919)

We'll be publishing these as proper Internet-Drafts once submissions open back up at IETF in a week or so. In the meantime, if you have any feedback then please let us know on the MSCs 🙂

🔗Random MSC of the Week

The random MSC of the week is... MSC3032: Thoughts on updating presence!

A loose collection of thoughts on how presence (the ability to see whether people are online/office) may be improved at the Matrix protocol level, and how it could be integrated into a profiles-as-rooms feature (MSC1769). Check it out if presence is something you're interested in!

TravisR explains

A soon-to-be working group within the IETF called "More Instant Messaging Interoperability" (MIMI) is aiming to solve, well, messaging interoperability for primarily reasons of the EU Digital Markets Act (DMA). The DMA requires "gatekeepers" to interop with other platforms while maintaining the same level of encryption, and we think Matrix is the perfect fit for this use-case. While we'd likely be saying goodbye to Olm and Megolm in the process, we'd be saying hello to Messaging Layer Security (MLS) and its decentralized counterpart DMLS - a good thing in our books, at the moment.

In terms of what we've done this week in publishing our drafts (and soon to be real Internet-Drafts under the IETF process), we're formally proposing that Matrix's Federation API and event schema be used for messaging interoperability. Our very own Matrix spec process will be impacted by this sort of direction as it makes it (theoretically) "harder" to change details of the spec. To avoid it being extraordinarily difficult, we'll be nailing down some of the edge cases of the Federation API and event format ( 👀 extensible events) naturally as we work closer and closer to an RFC series. We'll also be making some architectural changes to our specification itself to better support half of it being in the IETF domain, like defining room versions more clearly and splitting non-core spec out of the way. It's worth noting that this is a relatively slow process as we work towards the deadline of DMA a few years from now, but the changes might be felt by the ecosystem on a more rapid scale.

At the moment, we're planning to attend IETF 115 to help keep Matrix on the map for MIMI and raise our feedback about the proposed working group charter. Discussions about whether Matrix is the correct fit are already ongoing, but expected to increase as we get closer to IETF 116 next quarter. We were also already at IETF 114 a few months ago where many of these conversations started.

Future work is currently expected to come through under my name, as have the current drafts (both with obvious input from Matthew as project lead). Watching this space and the spec process for updates is best 🙂

🔗Dash User-Contributed Docset

ChristianP says

The Matrix Spec 1.4 is now available as a Docset for the Dash offline documentation reader. You can install this docset from Dash's Preferences > Downloads > User Contributed. This docset will likely be kept up-to-date by me. This is not an official distribution channel of the Matrix Spec team – things may break.

If you're using the open-source reader Zeal, you'll have to install new versions manually: https://gitlab.com/jaller94/dash-matrix-spec#use-with-zeal

🔗Dept of Servers 🏢

🔗Telodendria (website)

Jordan Bancino says

Hi everyone, I'm working on a little Matrix project called Telodendria.

Telodendria is eventually going to be another homeserver implementation. It isn't one yet; I'm still in the very early stages of prototyping it, and writing some boilerplate code, but I've been encouraged to throw the project out there for more exposure, so here we are!

Telodendria is written in ANSI C, will use a custom flat-file database, and relies only on a POSIX system to be built and run. It won't pull in any dependencies; as much as possible will be written from scratch, including the HTTP stack, JSON parser, and any other baseline stuff a Matrix homeserver needs.

🔗Why?

One of the goals is simply to build a useful homeserver, but also just to learn about the inner workings of Matrix and the technology that supports it, as well as to have a bit of fun in the process.

At this point we've got Synapse, Dendrite, Conduit, Construct, and a few other great projects. So you're probably asking, What practical reasons are there to build another homeserver? The best answer to that is in Telodendria's manual, but what it really comes down to is being portable and lightweight. It'd be cool to have a Matrix homeserver server that can run anywhere, but specifically targets the more obscure operating systems like the BSDs. Additionally, it should be light enough to perform well on Raspberry Pis, routers, cheap VPSs, and other low-power and low-storage devices that might not be as capable of running a full database plus a hefty Matrix homeserver.

For me personally, I just want a homeserver that feels like it belongs on OpenBSD and is capable of handling my use case without having to install any third-party packages. I'm a digital minimalist that wants to cut down on his software requirements, and Telodendria is one of the ways I've set out to do that.

🔗Want to get involved?

There's definitely plenty of code and documentation to be written, so if you're looking for a challenge and believe in the project's philosophy, you're highly encouraged to get involved in whatever way you're able.

The development discussion happens entirely on Matrix. If you're unsure where to start, start by joining the project rooms listed in the manual. Do be sure to also check out main project website, which has a list of all the manual pages. The manual should contain much of the information you'll need to get started, but it's far from complete, so if you find the information to be insufficient, don't be afraid to ask questions in the rooms listed above.

🔗Conduit (website)

Conduit is a simple, fast and reliable chat server powered by Matrix

Timo on Conduit ⚡️ announces

Great news! The FUTO organization selected me for a grant to sponsor me working on Conduit. I want to finally work on the big remaining issues like threads, backfilling, spaces and so on. Also keep an eye on the Conduit v0.5 release. It is almost done and contains many bug fixes. You can already try it out by compiling conduit-next.

🔗Synapse (website)

Synapse is a Matrix homeserver implementation developed by the matrix.org core team

dmr announces

A lot of the Synapse team are out at the moment; we have mostly been in maintenance mode, both for the project and the Matrix.org deployment. With that said: we released Synapse 1.70.0 on Tuesday followed by a 1.70.1 patch release today. Highlights include:

• better support for threads,
• full support for Matrix 1.3 and 1.4, and
• small fixes to the experimental faster joins work.

Thank you as ever to our community of contributors, server operators and users who've been involved in this release. We'll be cutting a release candidate for Synapse 1.71 on the upcoming Tuesday (1st November), aiming to release the week after (8th November).

As for this week: we've been testing Synapse against the recent Python 3.11 release, dealing wit h CI deprecations and working through our backlog of old PRs. Lots of small things to juggle!

🔗Homeserver Deployment 📥️

🔗Helm Chart (website)

Ananace announces

Since I happen to have a few free minutes this friday;

My Helm Charts continue to stay up-to-date, with element-web at 1.11.12 and matrix-synapse on 1.70.0 (though refer to #homeowners:matrix.org before updating)

Ananace reports

And another little update on my Helm Charts; matrix-synapse 1.70.1 is now available as well

🔗Dept of Clients 📱

🔗Nheko (website)

Desktop client for Matrix using Qt and C++17.

Nico announces

I guess the most exciting news is that the macOS M1 builds are now merged to master and will be available for the next release. Seems like those are even faster on macOS that the intel builds! (Time from launch to be able to send a message is about 1 or 2 seconds.) The builds are using the generous cirrus CI open-source offering, so thank you!

Another good news is that a fox fixed the upload widget sometimes breaking Nheko when trying to upload specific files on some platforms. Apart from that there were also minor fixes to room sorting in communities, performance fixes to the parent community links as well as work on enabling more warnings when developing Nheko (to ensure our code is better quality, more secure and less error prone).

If you want to find out more about Nheko, our official community is currently being set up at #community:nheko.im!

🔗Element Web/Desktop (website)

Secure and independent communication, connected via Matrix. Come talk with us in #element-web:matrix.org!

Danielle says

• Along with some bug fixes we’ve been adding more updates to some features currently in Labs!

  • Check out a newly improved Threads; with recent updates deployed, threads notifications should be much more reliable these days. We’ve still got more work to do but the improvements are great.
  • Video rooms and Element Call in the desktop version now supports screen sharing.
  • The rich text editor is also getting regular updates and expanded functionality.

• In the pipeline for us over the next few weeks are improvements to notifications and matrix.to links.

🔗Element iOS (website)

Secure and independent communication for iOS, connected via Matrix. Come talk with us in #element-ios:matrix.org!

Ștefan announces

• In order to enhance our ability to test before launch we’ve now got Nightly builds on ElementX iOS. Our internal testers are able to use the app for longer before we prep for release to the App Store and that will increase the quality of our product.
  • We’ve also made other improvements to our performance testing.
• The composer has had a few upgrades recently - keep your eyes open for that and let us know what you think!
• Work on voice broadcasting is moving ahead quickly
• We’re working on signing in via QR code and other enhancements in this area.
• And last but not least, ElementX is very close to getting e2e encryption support!

🔗Element Android (website)

Secure and independent communication for Android, connected via Matrix. Come talk with us in #element-android:matrix.org!

benoit announces

• The new app layout has been out for a few weeks now and we’re keeping an eye on feedback and numbers. So far it seems like most people like it though we’ve heard great ideas about improvements we can make in the future. Keep it coming!
• We’re working hard on increasing the test coverage in our app so that we have even more confidence in the app we’re pushing to the Play Store.
• Under Labs, there’s some new features. Check out:
  • The new composer. It’s What You See Is What You Get and hopefully a lot more straight-forward to use!
  • There’s also a new way to manage your devices and notifications on different clients.

🔗nheko-krunner (website)

A KRunner plugin to list joined rooms and possibly other things from nheko.

LorenDB says

I have updated nheko-krunner to work with the latest D-Bus API from nheko. There is no new release out yet, but expect to see a release (possibly with other cool things) after the next nheko release.

🔗Circles (website)

E2E encrypted social networking built on Matrix. Safe, private sharing for your friends, family, and community.

cvwright reports

Happy Friday all! Once again we have a new build of the Circles Android app for your beta testing enjoyment.

🔗Updates in this release (v1.0.5)

• Renamed the app back to "Circles". Technically the proper name of the app is "FUTO Circles", but it will show up on your home screen as simply "Circles", similar to how Google Photos is "Photos" and Google Maps is "Maps". The Circuli name was too hard for most English speakers to pronounce, and it didn't solve our other issues with the name. "FUTO Circles" should do the trick.
• We're keeping the Circuli name for our online service.
• Added QR-code-based device verification.
• Made registration tokens optional, i.e. it's up to the server whether to require them or not. Currently we do require registration tokens on our servers, and you can sign up with the token 0000-1111-2222-4444.

🔗matrix-rust-sdk (website)

Next-gen crypto-included SDK for developing Clients, Bots and Appservices; written in Rust with bindings for Node, Swift and WASM

ben announces

Long-awaited and with a bunch of final bug-fixes on the server side, this week eventually saw the merging of the sliding sync extensions, enabling e2ee and to-device message support via sliding-sync on main. With that, and some additional APIs on, a new Element-x with e2ee support was made available. A release that also features the latest work on the timeline API, which, too, has seen its fair share of progress this week - mainly internal fixes and debugging helpers.

As a result of the sliding sync work, just earlier today, an important PR was opened for jack-in, the experimental debugging TUI client based on matrix-rust-sdk (which we use for debugging sliding sync): now allowing you send (encrypted) messages, too.

Following last weeks announcement we also made the Rust-Sec public, indicating why we recommend upgrading to 0.6.1, which we released shortly prior.

Other than that, work has been progressed in the background on the pretty complex problem of async in uniffi and system-specific runners, namely libdispatch on ios rather than tokio, as well as work on uniff proc-macros.

AnsibleFest 2022 happened this week, and the work the community has been doing with Matrix got quite some attention! We got a mention during the Day 1 Keynote (YouTube) and again during an interview with theCUBE.net. Both are worth watching 🙂

Thanks to the shoutout from Adam in the Keynote, we've had 40 new people join the #social:ansible.com room 🚀 and lots of interest in Matrix at the Fest Community Booth. Huge thanks to @maxamillion:one.ems.host and @cybette:ansible.im for their time! ❤️

🔗Dept of Spec 📜

Andrew Morgan (anoa) says

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

New MSCs:

• MSC3914: Matrix native group call push rule
• MSC3912: Relation-based redactions
• MSC3911: Linking media to events
• MSC3910: Content tokens for media

MSCs in Final Comment Period:

• MSC3905: Application services should only be interested in local users (merge)

Closed MSCs:

• MSC3005: Streaming Federation Events
• MSC2775: Lazy loading over federation
  • Superseded by MSC3706 and MSC3902.

Accepted MSCs:

• No MSCs were accepted this week.

🔗Spec Updates

The Spec Core Team are continuing to work on spec maintenance in the run up to Matrix v1.5 (due next month!). Again, if you'd like to help out with small fixes and corrections to the spec, feel free to take a look at the list of open spec clarification issues. Thank you!

🔗Random MSC of the Week

The random MSC of the week is... MSC2700: Thumbnail requirements for the media repo!

This MSC has the goal of clarifying the mimetypes of media that a homeserver both MUST and SHOULD support thumbnailing for. The intention is to give clients a clearer picture of what file formats will receive a proper thumbnail before they are uploaded to the homeserver.

Comments on the MSC seem to suggest that the MSC as it stands does not completely solve the problem: while it does give clients an explicit list of supported mimetypes, the list is quite short. And the list of SHOULD mimetypes cannot be relied on.

The MSC also clarifies that encrypted media should always be uploaded with a mimetype of application/octet-stream, instead of the original media's mimetype, which seems like a welcome and uncontentious point. And finally, it defines 501 M_UNSUPPORTED to be returned instead of an internal server error on thumbnailing failure.

I believe the next step for this MSC is for the current threads to be incorporated into the text; so don't miss the threads when reading it!

🔗Dept of Servers 🏢

🔗Synapse (website)

Synapse is a Matrix homeserver implementation developed by the matrix.org core team

Brendan Abolivier announces

This week we've released Synapse 1.69! It comes with improved caching tools for third-party modules, and support for a bunch of experimental features, such as thread-aware read receipts (MSC3771) and an approval flow for new registrations (MSC3866). As part of this release, we've also laid out the removal schedule for the long-deprecated legacy Prometheus metric names, and the generate_short_term_login_token module API method. Read all about it on the matrix.org blog: https://matrix.org/blog/2022/10/17/synapse-1-69-released

Another big thing in Synapse 1.69 is experimental support for faster remote room joins! You can read more about it on the blog: https://matrix.org/blog/2022/10/18/testing-faster-remote-room-joins but briefly, we are ready for server admins to begin testing, with some caveats. If you've read the post and feel confident, turn it on, give it a spin and let us know how it goes!

Alongside 1.69, we're also disclosing a moderate severity vulnerability that we fixed back in Synapse 1.62. If your deployment runs a Synapse version older than 1.62, and is openly federating, please update to a more recent version of Synapse at your earliest convenience. More info on this in advisory GHSA-jhjh-776m-4765 and CVE-2022-31152.

This week we've also released the first release candidate for Synapse 1.70 (1.70.0rc1). This release will include experimental support for thread-aware notifications (MSC3773) and filtering (MSC3874), improved validation, advertising support for Matrix 1.3 and 1.4, and the usual load of bugfixes and internal improvements. We're very grateful to anyone helping us make Synapse more stable by testing and running release candidates, and reporting bugs to the issue tracker and general feedback to #synapse:matrix.org 🙂

🔗Dendrite (website)

Second generation Matrix homeserver

neilalexander announces

This week we released Dendrite 0.10.4 which contains the following features and fixes:

• Various tables belonging to the user API will be renamed so that they are namespaced with the userapi_ prefix
  • Note that, after upgrading to this version, you should not revert to an older version of Dendrite as the database changes will not be reverted automatically
• The backoff and retry behaviour in the federation API has been refactored and improved
• Private read receipt support is now advertised in the client /versions endpoint
• Private read receipts will now clear notification counts properly
• A bug where a false leave membership transition was inserted into the timeline after accepting an invite has been fixed
• Some panics caused by concurrent map writes in the key server have been fixed
• The sync API now calculates membership transitions from state deltas more accurately
• Transaction IDs are now scoped to endpoints, which should fix some bugs where transaction ID reuse could cause nonsensical cached responses from some endpoints
• The length of the type, sender, state_key and room_id fields in events are now verified by number of bytes rather than codepoints after a spec clarification, reverting a change made in Dendrite 0.9.6

As always, please feel free to join us in #dendrite:matrix.org for more related discussion.

gleachkr says

It's been a little while since our last update, but Populus development continues! In addition to the usual bugfixes, we've made a number of ergonomics improvements suggested by the experiences of other users at my university. These include:

1. Buttons for message actions (react, redact, reply, and so on) are now displayed in a way that doesn't overlap with sender names

2. Avatar images for discussions can now up uploaded simultaneously with discussion creation.

3. Older collections of discussions can be "archived" using m.lowpriority

4. Moar tootips!

We've also made some minor graphical improvements: loading messages are now indicated with a nice low-contrast SVG hint, rather than the literal-minded "loading message" message. Some icons have been improved, and the bartab (lines in the margins) display logic has been improved. And, we're now on the latest JS-SDK version.

ben announces

While the sliding sync extensions are being tested and bugs found during the tests reported and fixed, the FFI for the new timeline API has been approved and merged this week. The third big chunk that was merged this week, was a refactoring to Replace QR with SAS verification and the yet to be merged signaling for SAS verification.

While forcing the (not clearly spec'ed) sending of authentication tokens for get_profile and get_display_name, we've also noticed a bug where we sometimes, unintentionally include the access_token in debug output - and fixed that. We will be providing a patch release and RustSec about this soon.

Other than that, this week has seen many smaller fixes, like making the store-setters on client-builder actually adhere to the builder pattern or removing string from storerrors, and improvements like the API to set local trust or setting workspace wide dependencies for uniffi and others.

Happy TWIMday everyone! Thib is away this week again, so I'm covering for him as your host in this edition of This Week In Matrix.

🔗Matrix Live 🎙

Following up on last week's tutorial about using Docker Compose to install Synapse, this week Thib explains how to use Ansible to deploy your own Matrix homeserver.

🔗Dept of Status of Matrix 🌡️

TravisR reports

Earlier in the year, t2bot.io passed 1 Million known rooms and now it's passed 10 Million bridged users (10,039,915 users to be exact, at time of writing). Most of these users will be people who have participated in a channel/chat on Discord or Telegram that was bridged to Matrix through t2bot.io's free service, with about 500 thousand being active each month.

Approximately 8 Million of the users are from Telegram, covering about 11% of all Telegram users (previously 15% based on information available at the time). The remaining 2 Million are Discord users, roughly 0.5% of Discord's user base. For perspective, t2bot.io has just over 683 Million events in the database and is bridging between 30 and 40 thousand people a day.

Like last time, this is just a milestone update, though it's also a good reminder to host your own server if you can. Element's own hosting platform is a great option if you'd like to have a server without running it yourself, and Beeper offers a richer bridging experience than t2bot.io can feasibly provide. If you'd like to go down the self-hosting route, check out Thib's video guide on hosting synapse or last week's Matrix Live for a better understanding of what hosting Synapse actually means.

As for an interesting statistic: despite not having much functionality that deals with Spaces, t2bot.io can see 2687 Spaces from the wider world. The plan in the coming months is to support a way to bridge a whole Discord server to a Matrix Space, making this statistic hopefully more interesting as time goes on.

🔗Dept of Spec 📜

uhoreg reports

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:

• MSC3874: Filtering threads from the /messages endpoint
• MSC3873: event_match dotted keys
• MSC3872: Order of rooms in Spaces

🔗Spec Core Team

The Spec Core Team has been continuing to push forward on the spec. Several new MSCs have been opened recently. The Spec Core Team is available in #sct-office:matrix.org when MSC authors think that they are ready for primetime.

🔗Random MSC of the Week

The random MSC of the week is... MSC2162: Signaling Errors at Bridges!

Bridges sometimes are unable to relay messages to the remote service for one reason or another. This MSC proposes a way to allow bridges to indicate that a message failed to be delivered, and allow users to tell the bridge to retry.

🔗Dept of Servers 🏢

🔗Synapse (website)

Synapse is a Matrix homeserver implementation developed by the matrix.org core team

Brendan Abolivier says

This week we've released Synapse 1.66.0rc1! This upcoming release deprecates delegating email validation to an identity server (more info here) and includes improved validation around user-interactive authentication, support for a couple of experimental features, as well as the usual batch of bug fixes and performance improvements 🙂

As always, any help with testing and feedback on this RC is appreciated! Feel free to drop any feedback or bug report in #synapse:matrix.org and the Synapse repo respectively.

🔗Dendrite (website)

Second generation Matrix homeserver

neilalexander announces

This week we released Dendrite 0.9.5 which includes a number of fixes, particularly for federation:

• The roomserver will now correctly unreject previously rejected events if necessary when reprocessing
• The handling of event soft-failure has been improved on the roomserver input by no longer applying rejection rules and still calculating state before the event if possible
• The federation /state and /state_ids endpoints should now return the correct error code when the state isn't known instead of returning a HTTP 500
• The federation /event should now return outlier events correctly instead of returning a HTTP 500
• A bug in the federation backoff allowing zero intervals has been corrected
• The create-account utility will no longer error if the homeserver URL ends in a trailing slash
• A regression in /sync introduced in 0.9.4 should be fixed

As always, please feel free to join us in #dendrite:matrix.org for more Dendrite-related discussion.

Matrix server setup using Ansible and Docker

Slavi reports

Thanks to Aine of etke.cc, matrix-docker-ansible-deploy can now set up the new Postmoogle email bridge/bot. Postmoogle is like the email2matrix bridge (also already supported by the playbook), but more capable and with the intention to soon support sending emails, not just receiving.

See our Setting up Postmoogle email bridging documentation to get started.

🔗Dept of Bridges 🌉

Aine reports

follow-up to Slavi's announcement: Postmoogle is here!

Actually, he explained it pretty good, so here are some additional links

Source code and Roadmap with implemented and planned features and as usual, say hi in the #postmoogle:etke.cc

🔗Dept of Clients 📱

🔗Quadrix (website)

A Minimal, simple, multi-platform chat client for the Matrix protocol.

JFA says

Quadrix v1.2.5 has been released! The update is already available for Linux, MacOS and iOS. The Windows and Android updates are awaiting approval from the respective stores. This release has mostly "under the hood" improvements (upgrade to React Native 0.69, React 18 and other key dependencies), but also fixes a few bugs and brings minor UI improvements.

Great news: Quadrix finally made it to https://matrix.org/clients/ :-) Many thanks to @madlittlemods:matrix.org!!!

Please leave feedback/comments at #quadrix:matrix.org or in the issues at https://github.com/alariej/quadrix (stars welcome :-))

kittykat says

• Our code style guide has now finished review and we are now working on updating eslint-plugin-matrix-org to match it
• We will be release an RC2 to fix a regression around progress bars

In labs (you can enable labs features in settings on develop.element.io or on Nightly):

• We’re working hard on updating Threads, squashing bugs and improving performance. We have several MSCs open introducing new functionality to read receipts so that notifications work better than ever.

🔗Element iOS (website)

Secure and independent communication for iOS, connected via Matrix. Come talk with us in #element-ios:matrix.org!

Ștefan reports

• We’re working hard on making the new layout ready for general use, squashing bugs and taking names until everything is in tip top shape. We have a test flight build out: we’ve delayed the release to next week while we iron out the last creases.
• In ElementX land we have started on adding analytics and Xcode Cloud support and have updated our logging strategy. We will also start adopting sliding sync and using the new Rust Timeline providers

🔗Element Call (website)

Native Decentralised End-to-end Encrypted Group Calls in Matrix, as a standalone web app

Robin announces

Element Call v0.2.7 and v0.2.8 have been released this past week, adding local volume control, full screen mode, audio in screen sharing and, ahem, fixing an embarrassing bug where we broke walkie-talkie mode... 🐑 Oh, and it's also all in TypeScript now. 🚀 https://github.com/vector-im/element-call/releases/tag/v0.2.7

🔗Dept of SDKs and Frameworks 🧰

🔗simplematrixbotlib (website)

simplematrixbotlib is an easy to use bot library for the Matrix ecosystem written in Python and based on matrix-nio.

HarHarLinks says

simplematrixbotlib has reached version 2.7.0, adding support for end-to-end encryption! 🎉 Come chat over at #simplematrixbotlib:matrix.org!

Here is a summary of things that have happened since we last announced v2.6.3 on this channel:

• 🌐 The repo canonically moved to https://github.com/i10b/simplematrixbotlib, but the PyPI package remains available in the usual place.
• 🔒️ E2EE support! To enable it, simply install the optional e2ee dependencies. Find out how in the manual.
• 😄 Emoji verification support! Enable the option and you'll be able to interactively verify between the bot and your devices. (But mind that for now, in-room verification is not supported, but only to-device).
• ☝️ Fingerprint verification support! As an additional method, the bot will print it's encryption fingerprint so you can "manually verify".
• 🗄️ Extensible config file! It is now easier than ever to add your own configuration options to the built-in TOML config file.
• 🧹 The usual housekeeping, bumping matrix-nio to 0.19.0.
• 🗨️ I (HarHarLinks) will be presenting the library this weekend at #matrix-summit-berlin-2022:c-base.org! If you are in the Berlin 🇩🇪 area, come visit c-base!

The easiest to use bot library for Matrix. Get started in just 10 lines of code:

import simplematrixbotlib as botlib

config = botlib.Config()
config.emoji_verify = True
creds = botlib.Creds("https://home.server", "user", "pass")
bot = botlib.Bot(creds, config)

@bot.listener.on_message_event
async def echo(room, message):
    if botlib.MessageMatch(room, message, bot, PREFIX).is_not_from_this_bot():
        await bot.api.send_text_message(room.room_id, message.body)

bot.run()

Matrix Client-Server SDK for Rust

ben announces

With a few people out of office, this weeks has been one of the more quiet ones, but progress has been made non-the-less. Again a lot happens in draft PRs and the background, like with the upcoming Timeline API but also the path forward for integrating the crypto bindings into the js-sdk. There are a few notable PRs merged this week still improving the API (#972 and #973, #961), upgrading to latest ruma, removing dependencies (parking_lot) to improve compile times as well as merging the release infrastructure for crypto-js.

Henri Carnot reports

Hi all, quite a lot happened since the last twim post a few months ago.

In a nutshell, we refactored the feed page and user page for a better viewing experience. We also now allow displaying and commenting post images in a dedicated view. Also, you can now send follow request using knocking, thanks to profile as space support. (Yes, MSC is coming)

Finally, we have now multi account support, better stories display and refactored login and settings page.

Well... we almost modified everything :D
