This Week in Matrix 2025-07-11

🔗Matrix Live S11E04 – Gathering the community

You can find the Matrix Foundation's Events Working Group's room at #events-wg:matrix.org, all about Matrix Community Summit on their website, and Matrix Community Retreats at #workation-nation-general.

🔗Dept of Spec 📜

Andrew Morgan (anoa) {he/him} 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://spec.matrix.org/proposals.

🔗MSC Status

New MSCs:

• MSC4310: MatrixRTC decline m.rtc.notify
• MSC4309: Finalised delayed event on sync
• MSC4308: Thread Subscriptions extension to Sliding Sync
• MSC4307: Validate that auth_events are in the correct room
• MSC4306: Thread Subscriptions
• MSC4291: Room IDs as hashes of the create event

MSCs in Final Comment Period:

• MSC4222: Adding state_after to /sync (merge)
• MSC4210: Remove legacy mentions (merge)

Accepted MSCs:

• No MSCs were accepted this week.

Closed MSCs:

• MSC1998: Two-Factor Authentication Providers
• MSC3741: Revealing the useful login flows to clients after a soft logout
• MSC3105: Previewing UIA flows
  • The above 3 MSCs were closed due to dealing with the old auth system, which has been made obsolete by Matrix's next-gen auth system.
• [WIP] MSC4051: Using the create event as the room ID
  • Superseded by MSC4291

🔗MSC highlight: Room IDs as hashes of the create event

You may have noticed some placeholder MSCs being opened in the past half a year. One of them has now received content ahead of the others:

MSC4291 redefines room IDs to be the hash of the m.room.create event. As a part of the change, the server name component is being removed. If any software you maintain assumes that the server name is present in room IDs, you should stop parsing room IDs or at least fail gracefully if the server name isn't there.

We're going to propose FCP on MSC4291 in the next few days and a new stable room version including that and other security-sensitive changes from the placeholder MSCs is expected to follow relatively soon as well.

🔗Dept of Clients 📱

🔗Element X iOS (website)

A total rewrite of Element iOS using the Matrix Rust SDK underneath and targeting devices running iOS 16+.

Mauro Romito says

• Further improved accessibility in our app
• Introduces the development flag share pos which allows the SSS to resume the sync where it left off, however since is still an unstable feature the flag is off by default.
• 25.07.1 was released to the App Store on Monday

🔗Dept of VoIP 🤙

🔗Element Call (website)

Native Decentralised End-to-end Encrypted Group Calls in Matrix.

Timo K. announces

We continue to focus on the in app VoIP experience. This week version v0.13.0 and v0.13.1 were released:

🔗Native audio device handling for in-app calling

This release delivers a significant upgrade to the audio experience, with a particular focus on mobile devices. We've enhanced Element Call to provide a more native, phone-call-like experience when used within Element X.

Key improvements include:

• Support for earpiece audio output on both Android and iOS
• Convenient toggle button in the main menu to switch between earpiece and loudspeaker modes
• Proximity sensor integration that automatically turns off the screen when the device is held against your ear in earpiece mode

These changes represent a major step forward in making Element Call feel like a natural extension of your device's native calling capabilities.

🔗Dept of SDKs and Frameworks 🧰

🔗matrix-rust-sdk (website)

Your all-in-one toolkit for creating Matrix clients with Rust, from simple bots to full-featured apps, with bindings to Swift, Kotlin, WebAssembly, Go and more

poljar announces

While development has slowed down a bit due to summer holidays, it hasn't stopped completely. Here’s what’s new in the Matrix Rust SDK this week:

We have a new release: matrix-sdk 0.13.0 is out! Like the previous release, this one includes a fix for a security issue. You can find the full details in the release notes:
https://github.com/matrix-org/matrix-rust-sdk/releases/tag/matrix-sdk-0.13.0

Work on thread support continues. This week adds support for threaded read receipts.
(#5364)

The EventCacheStore is gaining support for IndexedDB, moving us closer to persistent event caching in web environments.
(#5343)

We now cache the supported server versions retrieved from the /versions endpoint, reducing unnecessary network requests when initializing a client.
(#5357)

The FFI bindings can now dynamically reconfigure the file path where logs are stored.
(#5380)

Finally, we’ve started migrating the codebase to the Rust 2024 edition, thanks to Jonas Platte.
