🔗Dept of Spec 📜

Andrew Morgan (anoa) {he/him} announces

Here's your weekly spec update (back from the dead)! 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://spec.matrix.org/proposals.

🔗MSC Status

New MSCs:

• There were no new MSCs this week.

MSCs in Final Comment Period:

• MSC4452: Preview URL capabilities API (merge)
• MSC4095: Bundled URL previews (merge)

Accepted MSCs:

• MSC3959: Sliding Sync Extension: Account Data

Closed MSCs:

• No MSCs were closed/rejected this week.

🔗Spec Updates

The Spec Core Team has been focusing intensely on the various Matrix 2.0 MSCs these past few weeks, with the intention to getting them ready before the Matrix conference in October.

The following is a list of the current status of each MSC, courtesy of @Johennes:

Updated MatrixRTC pulse check:

• 🟢 MSC4140: Cancellable delayed events - Merged
• 🟡 Clarifications for MSC4140: Cancellable delayed events - Open, review changes requested
• 🟡 MSC4354: Sticky Events - 2 / 8 checkboxes (unchanged from last week but there was good progress on the discussion threads on the MSC)
• 🔴 MSC4480: Sliding Sync Extension: Sticky Events - Proposed for FCP readiness as of this week, waiting on initial SCT review
• 🔴 MSC3960: Sliding Sync Extension: Receipts - Tracking for review
• 🟡 MSC4538: Sliding Sync Extensions: To-Device messages - Proposed for FCP, currently Ready for FCP ticks
• 🟡 MSC4543: Sliding Sync Extensions: End-to-end encryption - Proposed for FCP, currently Ready for FCP ticks
• 🟡 MSC4143: MatrixRTC – Real-time communication over Matrix - 6 / 8 checkboxes (unchanged from last week)
• 🟡 MSC4195: LiveKit transport for MatrixRTC - 3 / 8 checkboxes (unchanged from last week)
• 🟡 MSC4196: Voice and video calling application for MatrixRTC - 1 / 8 checkboxes (unchanged from last week)
• 🔴 MSC4075: MatrixRTC invites and notifications - Proposed for FCP readiness as of this week, waiting on initial SCT review

Regardless, we did have some URL preview improvement MSCs slip through into FCP, which is nice to see.

MSC4095: Bundled URL Previews especially, as it helps reduces the resources needed on the homeserver by either only requiring the sending homeserver to download the linked page, or allowing clients to download the preview instead.

Sky reports

Some of you may already know the #cs-auto-open_reg:codestorm.net policy list and some of you may even be using it. What many of you probably dont know yet is the history behind it. I wrote a small blog post series where I go trough the initial problem, what I've tried that failed and what eventually ended up working and where we are with it today. I think its nice to sometimes read a story of something actually working out in the end and I think we already have enough blog posts talking about how hard matrix is to moderate and what all is bad about it so here is my contribution to that with a positive story. So, I hope you enjoy it and maybe even learn something nerdy and cool while reading it :)

🔗Dept of Servers 🏢

🔗Venator (website)

Venator is an independently maintained Matrix homeserver, written from scratch in Go using the mautrix-go SDK.

nex (it/she) (away -> tbd) announces

Venator v0.1.0a4 was released, bringing exciting new goodies like OAuth2 login support, tangible performance enhancements, a disproportionate number of bug fixes, and I threw in some teasers for early outbound federation support too. Read more about it in the release notes, and/or come discuss the project in #venator:starstruck.systems. Also thanks to everyone who has starred the repository! 🐟️

🔗Dept of Clients 📱

🔗Harmony (website)

catcraft says

Hello everyone!

Harmony v0.6.0 just released, with support for changing room-scoped profiles, server-side search, profile timezones, and improvements to device verification. If you missed the previous entries, Harmony is a JavaScript-based, modular, extensible Matrix client with an open plugin system.

Speaking of plugins, a few more plugins have been released alongside v0.6.0, adding support for setting/displaying user pronouns (MSC4247) and banners (MSC4427). They can be found here. With these, as well as the biographies plugin and builtin timezones plugin, Harmony can now display (and configure) some of the more common profile fields in use today. Hooray!

Since v0.4.0, we've also added support for silent replies, room member management, and stickers. You can find the full changelog for all versions here.

You can find the latest release on the releases page on Codeberg, and you can also join the Harmony rooms to get announcements and chat about the client:

• Space
• General room
• Plugin developer room

🔗Nexus (website)

Matrix client made with Flutter and a Gomuks backend.

QuadRadical (Ping) announces

Hello TWIM! It's been a while since the last update on Nexus, but quite a lot has happened!

• iOS support! Nexus can now be built and run on iOS by sideloading an unsigned .ipa. However, there hasn't been too much testing here, so there may be bugs. If you try Nexus on iOS and run into any issues, please let me know in our Matrix room.
• MacOS support has come a long way, including proper DMG builds and a number of platform-specific fixes and improvements.
• Push notifications! Nexus now has UnifiedPush support on Android and Linux, so it can run fully in the background, and be woken up in the background by your UnifiedPush distributor. FCM is also supported for Android, so you don't need to install a separate UnifiedPush distributor. As part of this update, we also introduced a new Notifications page where you can see all your past notifications.
  • Push notification support in Nexus is very new, and is quite a complex feature, especially on Linux, and thus comes with some bugs. If you run into anything, please let me know in our Matrix room. Support for picking an UP distributor instead of using the default on your OS is also planned.
• A new emoji picker, written from scratch by me. This works far better than the last package we were using, and will enable support for custom emoji at a later stage.
• Better rendering of timestamps and state events.
• Support for blocking invites and MSC4494.
• And, as always, a whole lot of bug fixes 🙂

🔗Initial release progress

I know that in some previous TWIMs I suggested that I would publish a release soon, but since then I decided that I would like Nexus to be in a very good state before an initial release.

There's good news on that front: We are getting close. I've added a milestone on the forge for all the issues that need to be fixed before v1.0.0, though I will likely find some more bugs that need to be squashed.

You can take a look at it here: https://nexus.federated.nexus/milestone/1

🔗Element X iOS (website)

A total rewrite of Element iOS using the Matrix Rust SDK underneath and targeting devices running iOS 17+.

Mauro reports

Hi everyone! Here's what the Element X iOS team has been up to this week:

🔗✨ New and improved

• Notification counts in the room list: the room list now shows how many notifications you have in each room, and the badge on the app icon uses the same counts, so the two should always match.
• Smoother history loading: loading older messages in a room is now more reliable, and this is now on for everyone.

🔗🚧 In progress

• Forwarding multiple messages: we made steady progress on letting you select several messages at once and forward them to more than one room in one go.
• Native calls: work on the new built-in calling experience continues, and call buttons now also show up on macOS when this experimental feature is turned on.
• Multi Account support: preparatory work has started to finally bring one of the most requested features ever.

🔗🐛 Fixes

• A round of polish for iOS 27: we fixed the iPad split view layout, some overly bright toolbar elements, and toolbar buttons on macOS.
• The side tab bar no longer flickers or disappears when you resize the window.
• Fixed a crash caused by some unusual status emojis on user profiles.

🔗Element Web/Desktop (website)

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

David Langley says

🔗🌴 User Status enabled by default in Element Web

Going on Holidays? Lucky you, let people know with with the User Status feature. Use presets like 🌴 Away or set your own custom emoji/message combination. From Tuesday 29th of September this is enabled by default on Element Web. This will only work if User Status is enabled on your homeserver(include_profile_updates_in_sync in homeserver.yaml). It does not yet support federation but that is being worked on.

See MSC4426: Profile Updates, MSC4429: Legacy Sync, and MSC4262: Sliding Sync

🔗📌 Improved timeline scrolling and navigation is coming to Labs

Tired of clicking a matrix.to link only for Element Web to drop you at... well, the wrong message? Good news, we have been hard at work on a new timeline that should land you in the right place.

The new timeline aims to make navigation feel much more reliable, with:

• Fewer unexpected jumps while loading messages
• More reliable "Jump to bottom" and "Jump to unread" buttons
• An unread marker that stays where you expect it to
• Improved keyboard navigation, including moving through messages one by one (coming soon).

It is currently experimental and there are some known bugs, so please give it a try and let us know what you find.

It is already available on develop.element.io/desktop nightly, and will be available in the general releases from Tuesday 29 September. Go to All Settings -> Labs -> User interface to enable it.

We would love your feedback and bug reports. Click here to do just that, or find out more about what to expect.

🔗📄 Read PDFs without leaving the conversation

Need to check a PDF while discussing it in a room in Element Web/Desktop? You can now open it in the right panel, so you can read and chat side by side. No more switching back and forth between tabs.

The preview happens entirely in your client, there's no server-side conversion involved.

The PDF reader is currently in Labs 🧪. Try it now on develop.element.io or Element Desktop nightly by enabling Open PDFs in Labs. Or you can enabled it in the general Element Web release from the 29th of September.

🔗Commet (website)

Commet is a client for mobile and desktop with a modern UI and fun features!

airyz reports

The long awaited v0.5 is finally here! By far the biggest highlight of this update, (and the reason it took so long to develop) is adding support for Widgets, which allow you to embed custom tools and games in to your chat rooms. The introduction of the Widgets API opens up many new possibilities to customize your experiences on Matrix, and provides a great foundation for us to build on top of for even more interesting features in the future.

🔗🎮 Widgets

Commet being built in Flutter presented some interesting challenges in developing widgets, since widgets are web apps and thus require a webview to run. While it is possible to embed webviews inside a Flutter app, there were lots of limitations and performance issues with this approach and the quality did not meet our standards. After some experimentation we ended up with a few different implementations of widget runners to try and get the best overall experience for each currently supported platform.

The most interesting implementation was for Android, where we are spawning a new activity with its own webview using Android's split-screen API. This was significantly more performant than embedding the webview in Flutter itself as it completely bypasses the expensive compositing stage, and allows the heavy processing to occur separately with minimal impact on the main Commet instance. This works especially great on tablets in desktop mode (and one user reported it working well in Android based VR headsets!), where the two activities can be manipulated in floating windows. This inspired the implementations for the desktop version of the app as well, where we now have a separate Rust based process acting as the host on Windows, and an implementation utilizing instances of chromium already installed on your system on Linux. We would have liked to use the same Rust process on Linux, but due to limitations of WebKitGTK (lack of WebRTC support) have had to go with chromium for now.

In addition to our support for the Widgets API, we have also been developing some widgets of our own: A collaborative drawing game and a way to watch YouTube videos with your friends. These are both implemented using Element Call in SDK mode for real time communication, and are both in very early alpha!

🔗☎️ Experimental Support for Encrypted Element Call

After a lot of work, we are finally shipping initial support for end to end encryption in our implementation of MatrixRTC / Element Call. It is currently marked as experimental, so it needs to be toggled on before it can be used, and we are looking for user feedback to see where it may need improving.
