Hey everyone! Thib is out today, so I'll be exceptionally hosting TWIM in his stead this week. Let's have a look at what's been going on in Matrix-land!

Open Tech Will Save Us #16 🎙

The 16th edition of our virtual meetup Open Tech Will Save Us happened this week! This edition featured a few very interesting projects:

• Quentin and Maximilien from Deuxfleurs are creating Garage, a robust and distributed storage backend that can run on old computers. Who can use it? Why? And when should I not use it? Let's find out!
• Nathan from the Guardian Project is working with wind, butter, and rasperries to provide applications and messaging to people in low-connectivity areas. A fascinating dive off the grid.

Dept of Status of Matrix 🌡️

andybalaam says

Matrix's Outreachy intern for this summer has been chosen! Usman is starting in early June, and will be working on experiments with Starring Messages! He will be blogging every two weeks, so look out for more updates.

Dept of Spec 📜

Andrew Morgan (anoa) 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

New MSCs:

• MSC3825: Obvious relation fallback location
• MSC3824: Login/register indication on SSO redirect
• MSC3823: A code for account suspension

MSCs in Final Comment Period:

• MSC3604: Room Version 10 (merge)

Merged MSCs:

• No MSCs were merged this week.

Spec Updates

The upcoming release of Matrix v1.3 is still in the works, but near! Expect a solid release date to be announced next week.

Random MSC of the Week

The random MSC of the week is... MSC2872: Move the widget title to the top level of the definition!

A bite-size MSC which aims to clean up the definition of a widget state event... by moving the "title" field to the root of the state event, alongside the existing "name" field.

This MSC needs someone to write an implementation in at least one homeserver and client to move forwards. Perhaps that someone could be you?

Dept of Servers 🏢

Synapse (website)

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

squah reports

This week we cut two release candidates for Synapse v1.60, which include:

• New config options to limit the total memory usage of Synapse.
• The ability to reload cache factors of a running Synapse instance using SIGHUP.
• A new module callback to handle federation spam.
• Experimental support for MSC3787: Allowing knocks to restricted rooms and MSC3818: Copy room type on upgrade.
• Many bug fixes and internal improvements!

Meanwhile work continues on fast room joins and testing Synapse with workers on Complement. We'd like to remind readers that the fast room joins feature is highly experimental right now and we do not recommend enabling it on production homeservers just yet.

Synapse admin scripts (website)

Pierre announces

Morning, maybe it's useful for someone else, I just published my admin scripts for synapse. It's still WiP but it make some basic stuff that I needed in my organisation :

• System notify users (all users/users from a list, specific user)
• delete sessions/devices not seen for X days
• purge the remote media cache
• select rooms with various criteria (external/local/empty/created by/encrypted/cleartext)
• purge history of theses rooms
• shutdown rooms

https://git.fout.re/pi/matrixadminhelpers

It's my first python project, so the code may not structured as it should, I'm still learning, and it's early alpha :)

Dendrite (website)

Second generation Matrix homeserver

neilalexander says

This week we released Dendrite 0.8.6 which contains a number of fixes and tweaks:

• Room versions 8 and 9 are now marked as stable
• Dendrite can now assist remote users to join restricted rooms via /make_join and /send_join
• The sync API no longer returns immediately on /sync requests unnecessarily if it can be avoided
• A race condition has been fixed in the sync API when updating presence via /sync
• A race condition has been fixed sending E2EE keys to remote servers over federation when joining rooms
• The trusted_private_chat preset should now grant power level 100 to all participant users, which should improve the user experience of direct messages
• Invited users are now authed correctly in restricted rooms
• The join_authorised_by_users_server key is now correctly stripped in restricted rooms when updating the membership event
• Appservices should now receive invite events correctly
• Device list updates should no longer contain optional fields with null values
• The /deactivate endpoint has been fixed to no longer confuse Element with incorrect completed flows

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

Dept of Clients 📱

Nheko (website)

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

Nico announces

We added a way to edit permissions in Nheko now. It is an unconventional drag and drop dialog, where you drag users and permissions between different roles. We are hoping that this will make powerlevels easier to understand. Be careful when trying it, the wrong powerlevels might make your room unusable. Now... the bad part about that is, that powerlevels add around 50-100 new strings to translate... Help is appreciated! <3

Nheko now also supports fallback keys, which should make E2EE more reliable after long periods of being offline and you can send images by pressing enter again. The privacy screen is also now fixed for separate room windows and our flatpak supports more image formats.

Element Web/Desktop (website)

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

Danielle announces

• On Element Web this week we’ve smashed some bugs including those around Threads.
• Threads work continues as we’re aiming to improve the notifications and read receipts to improve the experience.
• Continuing to make improvements to our automated tests.
• The team is driving to complete the work needed to move our new search experience out of Beta. We think this new search is easier to use and helps folks to find what they’re looking for faster.
• We’re also making improvements specifically for new users, this will include a new home screen, watch out for those!

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

• Video rooms; We’re ironing out some of the details to polish the experience

Element iOS (website)

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

Ștefan reports

• This week we’ve fixed a crash, and a few bugs; specifically the bug where some rooms were missing from the room list.
• On the iOS team generally we’re working towards a Sentry.io integration for better crash reporting to help us with this in the future.
• Live location sharing and other features are making great progress.
• Our new first time user experience will be ready for feedback soon!
• ElementX has been refactored to adopt Swift’s new structured concurrency.

Element Android (website)

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

adam says

• This week we added emoji14 support so if you want to hide 🫣 , salute 🫡 , or melt 🫠 for your friends, you’ll soon be able to! 🫶 (for Android 12 and above, or devices that support emoji14)
• We’re getting ever nearer to a new sign up flow for new users. Our flow today can be confusing and complex, especially when all you want to do is chat with friends. We’ve been working on simplifying the flow and we’ll announce a community testing session very soon!
• Also new this week, we’ve opened up a new layout of the app to a small selection of folks. These 15 people will trial the new layout for us, providing feedback along the way. We’ll be opening it up to more feedback soon.

Element (website)

Everything related to Element but not strictly bound to a client

Danielle reports

Hello and happy Friday!

Threads

• Threads are still in progress as we continue to make progress on the notifications and sort/ordering work that remains.
• In order for notifications to work better, we need read receipts to be updated. We’ve got several MSCs ongoing, along with a few Proof of Concepts (PoCs) to move us forward.
  • MSC3771: Read receipts for threads
  • MSC3772: Push rule for mutually related events
  • MSC3773: Notifications for threads
• With that we’ve also updated some layouts and completed some bug fixes, on all platforms.

Community testing

• Keep your eyes peeled on #element-community-testing:matrix.org for more info on our next testing sessions.

Dept of SDKs and Frameworks 🧰

Trixnity (website)

Multiplatform Kotlin SDK for Matrix

Benedict says

Trixnity 2.1.0 has been released. It includes support for Server-Server-API endpoints (client and server) and fetching missing TimelineEvents in client. The latter is used for fragmented timelines: If you want to show a timeline starting from any EventId and RoomId (e. g. from unread marker), Trixnity will try to fetch missing TimelineEvents from server. If you reach TimelineEvents, that are already saved in the local database, the timeline fragments are merged magically 🧙

Ruma (website)

A set of Rust library crates for working with the Matrix protocol. Ruma’s approach to Matrix emphasizes correctness, security, stability and performance.

Kévin Commaille announces

Since our last update from about a month ago, we had two bugfix releases:

• Ruma 0.6.2 added methods to get the current room powerlevels from a StrippedPowerLevelsEvent and to get a user's membership whether the state event is redacted or not, and added a missing export to track member changes.
• Ruma 0.6.3 fixed the serialization and deserialization of events with a dynamic event_type and added convenience constructors for logging in with a UserIdentifier.

We have also landed a bunch of internal work:

• Improvement in our macros, notably to support unstable prefixes for event types.
• Some cleanup like removing some dead code, removing unnecessary PartialEq implementations, and fixing missing feature flags.
• The minimum supported rust version is now 1.59 and we use the Rust 2021 Edition.
• We started to refactor our tests to have more helpful failure messages.

And there are of course new fixes and features for our next release:

• Make sure that push rules don't apply to the user's own events
• Add support for MSC3700: Ignore content.sender_key
• Implement MSC3381: Polls

matrix-rust-sdk (website)

Matrix Client-Server SDK for Rust

ben reports

The majority of changes we've seen over the last week, where minor fixes in style, squashing of bugs and CI improvements as most work is currently happening in the background on Sliding Sync, mobile and UniFFI support. But there have been two additions worth mentioning: first, we've improved on the autojoin example for appservices, and secondly we've merged a community contribution to make resolving of room-alias more handy.

Matrix Dart SDK (website)

Matrix SDK written in pure Dart.

Henri Carnot announces

This week, the team released version 0.9.7.

This week, we migrated to Matrix Api Lite 1.0.0, our simple wrapper around the matrix API endpoints and data models. This means we are now using the v1.2 Matrix spec 🎉.

Also, support for HiveCollections as Database provider was added now that our patches to hive were accepted upstream. And we now provide a way to dump and restore the client local database.

Finally, we fixed a bug with where reactions were not properly discarded from the cache and some bugs in our e2e tests.

See you next time ;)

Matrix Live 🎙

Dept of Social Good 🙆

Thib says

Element has signed the open letter of the Global Encryption Coalition, of which we are members of. We are working with them to push back against any intrusive measures that could compromise the privacy of users.

Dept of Spec 📜

Andrew Morgan (anoa) 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

New MSCs:

• MSC3821: Update the redaction rules, again
• MSC3820: Room version 11
• MSC3819: Allowing widgets to send/receive to-device messages
• MSC3818: Copy room type on upgrade
• MSC3817: Allow widgets to create rooms

MSCs with Proposed Final Comment Period:

• MSC3267: Reference relations
• MSC3604: Room Version 10
• MSC2676: Message editing 🎉
• MSC3816: Clarify Thread Participation

MSCs in Final Comment Period:

• No MSCs are in FCP.

Merged MSCs:

• MSC3787: Allowing knocks to restricted rooms

Spec Updates

Some new MSCs popping up this week around widgets, room types, fixing notifications with threads and room version 11! Though note that the last one currently serves as a means for the Spec Core Team to publicly track what should be included in room version 11, and is by no means is its content considered final.

The Spec Core Team are currently focused on room version 10 and getting Matrix v1.3 out the door soon. There's also been some discussion on MSC2676: Message editing this week, with the intention of finally landing that in the spec. Thanks to richvdh for driving the charge there.

Random MSC of the Week

The random MSC of the week is... MSC1902: Split the media repo into s2s and c2s parts!

Homeservers currently make use of Client Server Media APIs to pull media from other homeservers over federation. This has worked for a long time, but is a bit of a confusing blur of the lines between client<->server and server<->server traffic. It also makes it difficult to require different authentication rules for clients versus servers.

This MSC aims to help clean that up. Take a look if you're interested!

Dept of GSoC 🎓️

Thib says

It's May 20, and Google has announced the results for its Summer of Code program.

This year the Matrix.org Foundation participated, and we could be granted the five slots we asked for!

• Jayesh Nirve is going to work on WebRTC support for FluffyChat, mentored by Krille
• nannako is going help handling multimedia files in kazv, mentored by tusooa
• Aditya Rajput will implement encrypted search for Matrix, mentored by cvwright
• Munukurthi Binesh is going to work on 3rd Party Authorised Room Membership, mentored by Cadair
• r0hit2005 will work on updating the implementation of VoIP support, mentored by Nico

Many thanks to all the candidates, we had some very strong proposals this year.

Dept of Servers 🏢

Synapse (website)

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

Brendan Abolivier announces

This week we released Synapse 1.59, which features a bunch of niceties including new features, bug fixes and performance improvements. Read all about it, including increased flexibility for workers and improvements on push rules, on the matrix.org blog!

Aside from this, the team is still hard at work and focusing on making Synapse better, among other things by looking at improving performances on room join and decreasing memory usage.

Dept of Bridges 🌉

matrix-hookshot (website)

A multi purpose multi platform bridge, formerly known as matrix-github

tadzik says

matrix-hookshot 1.7.0 is out

Last week new version of Hookshot came out starring the following changes:

• Docker images can now be built cross-platform. Thanks Paul for getting arm64 builds going!
• Improved GitLab push hook formatting: markdown commit hashes, link "N commits" to the list of commits, if there are more commits than can be shown only link instead, and show committer unless a single person committed and pushed
• RSS feed support got a configuration widget: now need for using bot commands anymore! (though they are still supported)
• Added widgets.openIdOverrides option to help developers test configuration widgets locally
• Fixed regression where GitHubRepo and GitLabRepo connection config options were not being honoured

and more! Visit #hookshot:half-shot.uk to follow the development in real-time.

matrix-appservice-kakaotalk (website)

A Matrix-KakaoTalk puppeting bridge.

Fair announces

Last week's testing updates are now in master!

Also included:

• Better error handling: if the backend hits an error that causes your connection to KT chats to be dropped, the bridge should notify you about it (not that it should ever happen in the first place, but you never know!)
• Better logging: the Node module can be configured to print the arguments of RPC commands received from / sent to the Python module. The example Node config includes a default set that should be helpful for general debugging.
• Room metadata bridging: setting an Open Chat title & topic from Matrix should work now!
  • Setting the title of a Direct Chat should work too, but topics remain unbridged (since KT Direct Chats don't have topics/descriptions)
• Defensive error handling: Attempts to add a non-friend user to a DM will be refused by the bridge, since KT only allows Direct Chats between friends
  • KT does allow "1:1 Open Chats" between non-friends, but those aren't bridged yet

Also, testing adds support for joining KakaoTalk rooms from Matrix, either by joining an existing portal or providing an Open Chat URL to the bot with a join command. ...However, I've been unable to test this, since KT is stingy about whom it allows to join Open Chats! So please give this a try if you can.

In other news, this bridge is now listed on Matrix.org! 🥳 Thanks Thib !

Also, for the time being, I will be taking a hiatus from this bridge & the LINE bridge, as I'll be quite occupied for the foreseeable future on account of having joined Element 🤩!! (The bridges aren't paused forever--I just have to work out the details of their future before making any promises I can't keep 🙂)

Special thanks to all those who have given feedback & advice on these bridges, and to Beeper for having sponsored their development ❤️

A bridge between Matrix and Discord.

Half-Shot announces

Hello! Just a notice to say that the `matrix-appservice-discord project has kindly been adopted by the matrix.org foundation, which means that hopefully there will be a lot more time available to maintain it than when it was my personal project! We expect to have a new update for you (the first one in 1.5 years) very soon! If you've got any questions about this, please feel free to ask in the usual spots like #discord:half-shot.uk.

Happy bridging!

Heisenbridge (website)

Heisenbridge is a bouncer-style Matrix IRC bridge.

hifi says

Release v1.13.0 🥳

• Read default port and listen address from config url (@BtbN)
• Improvements to pillifying IRC nicks, again
• Fixes for AUTOQUERY not always working correctly
• Allow anyone to use STATUS command to get their own status
• Filter control characters only for plumbs so people can send garbage to IRC if they wish from Matrix
• Support for converting IRC color codes to Matrix (@tjaderxyz)
• Fixed compose docker Synapse configuration for registration
• Improved Python 3.10 compatibliy (@BtbN)
• Hidden room to hide joins using restricted rooms join rule (@BtbN)

Some cool stuff this time around! Aside from many bug fixes this release has two great new features: IRC message colors and hiding invites from channels.

IRC colors are enabled by default and are rendered how your Matrix client sees fit. They can be disabled per network if needed.

Hiding joins works with room v9 restricted join rules feture to allow IRC ghosts to join rooms without an invite from the bridge bot first. This clears some clutter and may even make joining a bit faster in the long run - we will see. This feature is disabled by default and needs to be enabled by the bridge administrator as it is consiered a "labs" feature for now.

Go and get a Dell from GitHub, PyPI or matrix-docker-ansible-deploy!

Thanks!

Dept of SDKs and Frameworks 🧰

matrix-rust-sdk (website)

Matrix Client-Server SDK for Rust

ben says

Post release (we have release 0.5.0 last week) the main focus was on minor fixes and bigger features we had pending but didn't want to merge before. Aside from a few documentation and other minor fixes - among others switching to resolver v2 or more accurate power_level calculation - the biggest merge was around the FFI interface for Apple (iOS and Mac), which we have initial support for now 🎉.

The main work is currently happening behind the scenes, while we prepare for the upcoming tasks - like WASM and NodeJS support for the crypto-crate and work on UniFFI. We are also hardening our processes for improved security and risk management around our code base, dependencies and the potential to ship binaries.

👉️ We are very happy about the influx of people, who joined our developer community questions since the release. We'd like to take this opportunity again to invite anyone else interested in hacking on matrix in rust to check out our help wanted tagged issues and join our matrix channel at #matrix-rust-sdk:matrix.org.

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

Synapse 1.59 is out! Let's see what's new in this version.

Generic worker types

When Synapse instances are subject to high load, it can be useful to use workers to balance the load more effectively. Workers are separate processes that can take some of the load off the main Synapse process, and allow the homeserver to scale more effectively.

In the past, Synapse only provided a specific set of types of workers, each capable of handling a specific set of operations. For some time now we have been working on allowing more flexibility around worker configuration, which started all the way back in Synapse 1.12.0 with the introduction of a generic worker application type.

Synapse 1.59 furthers this work by deprecating the synapse.app.appservice and synapse.app.user_dir worker application types. Homeserver administrators should change the configuration of instances using these types to the generic synapse.app.generic_worker application type, and use the notify_appservices_from_worker and update_user_directory_from_worker to delegate application service and user directory work (respectively) to a worker.

See the upgrade notes for more information on this change.

Push rules

Push rules allow Matrix clients to define notification rules on a homeserver. One often reported issue with notification in Matrix is the fact that notifications are sent out when server ACLs, which define which server(s) can and cannot interact in a room, change. This is especially annoying during big waves of abuse, as there might be multiple servers that need to be banned from rooms, thus causing a lot of unneeded notifications.

Synapse 1.59 now supports silencing server ACL updates, by implementing the new push rule documented in MSC3786. However, since this MSC hasn't been incorporated into the spec yet, this behaviour is disabled by default in Synapse: see the implementation pull request for more information on turning it on.

Synapse 1.59 also allows third-party modules to validate and change the actions associated with an existing push rule via the Module API. This is helpful for modules wishing to, for example, configuring specific notification settings when new users register.

Everything else

As of Synapse 1.59, Synapse will not communicate the name of devices over federation (unless configured otherwise), in order to better preserve user privacy. See the upgrade notes for more information.

Also note that we have issued a patch release for 1.59 (1.59.1) which fixes a long-standing bug that started to bite a good amount of server administrators. Server admins that are looking into upgrading their instance to Synapse 1.59 are recommended to upgrade to 1.59.1 rather than 1.59.0.

See the full changelog for a complete list of changes in this release. Also please have a look at the upgrade notes for this version.

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 (in no particular order) Beeper, Dirk Klimpel, Šimon Brandner, henryclw and Andrew Do.

Hi all,

It’s been quite a while since our last independent E2EE review, and so we’re incredibly proud to present an entirely new independent security audit of vodozemac, our next generation native Rust implementation of Matrix’s Olm and Megolm E2EE protocols. The audit has been conducted by Least Authority, who specialise in comprehensive audits of security-sensitive decentralized technologies - and we are very grateful to gematik, who kindly shared the costs of funding the audit as part of their commitment to Matrix for healthcare in Germany.

This audit was a bit of a whirlwind, as while we were clearly overdue an audit of Matrix’s E2EE implementations, we decided quite late in the day to focus on bringing vodozemac to auditable production quality rather than simply doing a refresh of the original libolm audit. However, we got there in time, thanks to a monumental sprint from Damir and Denis over Christmas. The reason we went this route is that vodozemac is an enormous step change forwards in quality over libolm, and vodozemac is now the reference Matrix E2EE implementation going forward. Just as libolm went live with NCC’s security review back in 2016, similarly we’re kicking off the first stable release of vodozemac today with Least Authority’s audit. In fact, vodozemac just shipped as the default E2EE library in matrix-rust-sdk 0.5, released at the end of last week!

The main advantages of vodozemac over libolm include:

• Native Rust - type, memory and thread safety is preserved both internally, and within the context of larger Rust programs (such as those building on matrix-rust-sdk). This is particularly important given the memory bugs which libolm sprouted, despite our best efforts to the contrary.
• Performance - vodozemac benchmarks roughly 5-6x faster than libolm on typical hardware
• Better primitives - vodozemac is built on the best practice cryptographic primitives from the Rust community, rather than the generic Brad Conte primitives used by libolm.

Also, we’ve finally fixed one of the biggest problems with libolm - which was that the hardest bit of implementing E2EE in Matrix wasn’t necessarily the encryption protocol implementation itself, but how you glue it into your Matrix client’s SDK. It turns out ~80% of the code and complexity needed to securely implement encryption ends up being in the SDK rather than the Olm implementation - and each client SDK ended up implementing its own independent state machine and glue for E2EE, leading to a needlessly large attack & bug surface.

To address this problem, vodozemac is designed to plug into matrix-sdk-crypto - an SDK-independent Rust library which abstracts away the complexities and risks of implementing E2EE, designed to plug into existing SDKs in any language. For instance, Element Android already supports delegating its encryption to matrix-sdk-crypto; Element iOS got this working too last week, and we’re hard at work adding it to Element Web too. (This set of projects is codenamed Element R). Meanwhile, Element X (the project to switch Element iOS and Element Android to use matrix-rust-sdk entirely) obviously benefits from it too, as matrix-rust-sdk now leans on matrix-sdk-crypto for its encryption.

Therefore we highly recommend that developers using libolm migrate over to vodozemac - ideally by switching to matrix-sdk-crypto as a way of managing the interface between Matrix and the E2EE implementation. Vodozemac does also provides a similar API to libolm with bindings for JS and Python (and C++ in progress) if you want to link directly against it - e.g. if you’re using libolm for something other than Matrix, for example XMPP, ActivityPub or Jitsi. We’ll continue to support and maintain libolm for now though, at least until the majority of folks have switched to vodozemac.

In terms of the audit itself - we recommend reading it yourself, but the main takeaway is that Least Authority identified 10 valid concerns, of which we addressed 8 during the audit process. The remaining two are valid but lower priority, and we’ll fix them as part of our maintenance backlog. All the issues identified are excellent valid points, and we’re very glad that Least Authority have added huge value here by highlighting some subtle gotchas which we’d missed. (If you write Rust, you’ll particularly want to check out their zeroisation comments).

So: exciting times! Vodozemac should be landing in a Matrix client near you in the near future - we’ll yell about it loudly once Element switches over. In the meantime, if you have any questions, please head over to #e2ee:matrix.org.

Thanks again to gematik for helping fund the audit, and to Least Authority for doing an excellent job - and being patient and accommodating beyond the call of duty when we suddenly switched the scope from libolm to vodozemac at the last minute ;)

Next up: we’re going to get the Rust matrix-sdk-crypto independently audited (once this burndown is complete) so that everyone using the matrix-sdk-crypto state machine for Matrix E2EE can have some independent reassurance too - a huge step forward from the wild west of E2EE SDK implementations today!

– Matthew

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:

• [WIP] MSC3815: 3D Worlds
• [WIP] MSC3814: Dehydrated devices with SSSS
• MSC3813: Obfuscated events

MSCs with Proposed Final Comment Period:

• No MSCs had final comment period proposed this week.

MSCs in Final Comment Period:

• MSC3787: Allowing knocks to restricted rooms (merge)

Merged MSCs:

• No MSCs were closed this week.

Closed MSCs:

• MSC3790: Register Clients

Spec Updates

The Spec Core Team has decided to not include MSC3440 (threading via m.thread relations) specifically in the upcoming Matrix v1.3 release. We previously stated that it would be in v1.3, but there's a few unproven MSCs (namely MSC3773 (notifications for threads)) which make it feel improper to put threads into the spec at this stage. We're aiming for a future (very near) spec release to contain threads, assuming we can get enough of the feature landed. This is a very similar approach to what we did with Spaces: while the core feature existed as FCP-concluded for a while, we wanted to give some other MSCs a chance to land before writing it up formally.

As a follow-on from this, any implementations that are currently assuming "v1.3" spec support translates to threading support should note the following:

• Clients which are pre-emptively checking for v1.3 in /versions should stop doing that. Look for org.matrix.msc3440.stable as an "unstable" feature flag instead.
• Servers which offer MSC3440's behaviour should expose it on stable endpoints and expose org.matrix.msc3440.stable for clients to detect.
• Optionally, clients and servers can drop support for the org.matrix.msc3440 (truly unstable) flag, given clients & servers should have already upgraded.

At the spec level, we'll still be writing up MSC3440's dependencies (aggregations and friends), but will notably be missing MSC3440 specifically in v1.3. If folks can update their clients urgently, it would be massively appreciated!

Random MSC of the Week

The random MSC of the week is... MSC2596: Proposal to always allow rescinding invites!

A simple change to the auth rules to help prevent an edge case where one is able to invite a user, but not disinvite them as the latter requires a separate permission. The MSC attempts to solve this by always allowing the cancellation of invitations you've sent.

A small MSC, but one with some open threads still. Perhaps a good opportunity to go in and clean it up!

Dept of Servers 🏢

Synapse (website)

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

squah says

Hello everyone. This week the team cut a release candidate for Synapse v1.59, which includes:

• New module API support for editing push rules.
• Experimental support for MSC3266, federated room summary and MSC3786.
• Updates to support for MSC2285, hidden read receipts.
• Many bug fixes and internal improvements!

Meanwhile, the core team has looking at caches and memory usage: Erik has been looking at ways to reduce the memory usage of small servers, Shay's been adding some exciting new config options to limit the total memory usage of Synapse and David's added the ability to reload the cache factors of a running Synapse instance via SIGHUP.

In parallel, Olivier's been doing groundwork to reduce replication traffic for workerised Synapse deployments, Andrew (anoa) has been looking at media retention policies and work continues on faster room joins.

Dendrite (website)

Second generation Matrix homeserver

neilalexander reports

This week we've actually made two releases — Dendrite 0.8.4 and Dendrite 0.8.5 — which are both primarily targeting performance and bug fixes.

We've also released our new living documentation, which is available at https://matrix-org.github.io/dendrite/, which features new installation instructions and documents that will be helpful to Dendrite server administrators. We will be writing more documentation and expanding this over time.

Changes include:

• The built-in NATS Server has been updated to version 2.8.2
• Monolith deployments will no longer panic at startup if given a config file that does not include the internal_api and external_api options
• State resolution v2 now correctly identifies other events related to power events, which should fix some event auth issues
• The latest events updater will no longer implicitly trust the new forward extremities when calculating the current room state, which may help to avoid some state resets
• The one-time key count is now correctly returned in /sync even if the request otherwise timed out, which should reduce the chance that unnecessary one-time keys will be uploaded by clients
• The create-account tool should now work properly when the database is configured using the global connection pool
• Fixes a regression introduced in the previous version where appservices, push and phone-home statistics would not work over plain HTTP
• Adds missing indexes to the sync API output events table, which should significantly improve /sync performance and reduce database CPU usage
• Building Dendrite with the bimg thumbnailer should now work again (contributed by database64128)

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

Ement.el (website)

Matrix client for Emacs

alphapapa announces

Ement.el, a Matrix client for [GNU Emacs](https://www.gnu.org/software/emacs], received some more updates this week:

Additions

• New Transient-based command menu for room buffers, bound to ?.
• New command ement-list-members, which lists all members in a room.
• Member completion now completes from all members in a room (rather than only those whose messages have been seen).
• Power-level events are displayed.
• Grouped membership events have tooltips showing each member's individual event.
• When usernames are colorized, message bodies may optionally be colorized in a less intense shade of the same color, so they are easily distinguished yet easy on the eyes (and, of course, the shading is customizable).

Changes

• When displaying usernames in the margin, names that are wider than the margin are abbreviated, with the full name in the tooltip.

Fixes

• Typing notifications (recently broken--oops!).
• Sending direct messages marks new direct rooms as direct rooms.
• Event notifications for rooms not displayed in a buffer.

Dept of SDKs and Frameworks 🧰

matrix-rust-sdk (website)

Matrix Client-Server SDK for Rust

ben reports

The Rust Matrix team is very excited to announce the next major release Matrix SDK 0.5 "stores and native crypto", now available for everyone by adding matrix-sdk = "0.5.0" to their dependencies in their Cargo.toml. This first major release in about 8 months brings significant changes many have been waiting for:

• Better, safer, native-er crypto: matrix-sdk 0.5 ditches libolm in favor of Vodozemac, the completely fresh rust-native re-implementation of the crypto crate. It has also been audited, the report of which is scheduled to be released soon.
• Store revamp: the entire cache storage infrastructure for crypto and state has been restructured to allow for full plug-ability, with even the two default supported backends, sled and indexeddb both being separate crates now. And as a matter of fact, a community-driven sql implementation has already been published as beta (with postgres and sqlite support) by charlotte 🦝.
• WebAssembly; both of these changes also allow us to finally make WASM a Tier 1 supported target for the SDK. Not only does it build and even use the browser native indexeddb for permanent storage, we also have CI tests ensuring nothing will break this support going forward.
• Features, Features and Process: there's plenty more features and bug fixes in this release, e.g. native thumbnail generation support, as well as changes on our processes going forward.

For more details, check out the Release Notes.

Sidenote: If you want to contribute, or just learn Rust by actually doing it, we recommend taking a look team at the help wanted issues in our repo.

Dept of Bots 🤖

Who's In This Room Matrix Bot

Jake C says

If you use Matrix with the Signal bridge (or any bridge) with relay mode enabled, your guests have probably experienced the confusion where they don't know who else (on Matrix) is in the chat as only Matrix can double-puppet.

When this bot is added to a Matrix room, it will announce:

• Who the room members are when a new Signal user joins;
• When a Matrix user joins or leaves, who that Matrix user was.

I built it just this afternoon using the excellent matrix-bot-sdk, but it's in Typescript and has plentyful unit tests!

I don't currently have a public bot, but if anyone is interested please join #whos-in-this-room-bot-discussion:jakecopp.chat and say hello!

PRs for adding support for other chat apps (basically identifying which bridge from the puppeted username) are very welcome! https://github.com/jakecoppinger/whos-in-this-room-matrix-bot

Dept of Spec 📜

Andrew Morgan (anoa) 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

New MSCs:

• MSC3787: Allowing knocks to restricted rooms
• MSC3786: Add a default push rule to ignore m.room.server_acl events
• MSC3782: Matrix public key login spec
• MSC3780: Knocking on action=join
• MSC3779: "Owned" State Events
• MSC3775: Markup Locations for Audiovisual Media
• MSC3773: Notifications for threads
• MSC3772: Push rule for mutually related events
• MSC3771: Read receipts for threads

MSCs in Final Comment Period:

• No MSCs are in FCP.

MSCs with proposed Final Comment Period:

• MSC3787: Allowing knocks to restricted rooms

Merged MSCs:

• No MSCs were merged this week.

"Wowza, that's a lot of new MSCs!" I hear you say. This is actually a listing of the last 3 weeks, as it was pointed out to me that the last 3 editions of TWIM have not all features an MSC status update - which means some MSCs may not have necessary made it into the limelight.

As such, here's those from this past week, as well as the ones that were missed!

Spec Updates

It's that time of the year again - a new Spec release is on the horizon! Matrix v1.3 is expected to land sometime this month, and will include:

• MSC3440 (threads) + related MSCs
• MSC3787 (knock+restricted join rules)
• MSC3604 (room version 10)
• Any other MSCs which have so far been accepted, but not yet made it into the spec.

MSCs which land between now and v1.3 might get incorporated if easy enough, though chances are they'll slip to v1.4 (expected next quarter).

On top of that, the other bit of news is that the proposal-in-review label has now been removed from the matrix-spec-proposals repo and thus all MSCs. This doesn't mean your MSC is no longer in review! We simply found the label redundant along with the other labels in the process (it was attached to all MSCs which hadn't been accepted/merged yet, which means very little) and thus we decided to remove it to reduce noise.

Random MSC of the Week

The random MSC of the week is... MSC2881: Message Attachments!

This MSC has actually been potentially(?) superseded by MSC3382. In short, both look to provide a solution to the problem of attaching (multiple!) images to messages, such that clients can display an album of images in a single event in the timeline.

Check it out if you're interested in introducing such a feature!

Synapse (website)

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

Andrew Morgan (anoa) says

Synapse v1.58.0 was released this week! Check out the v1.58 blog post for the full scoop, but the highlights are:

• Our Docker images and Debian packages are now built from a dependency lockfile courtesy of Poetry. Props to David for leading the charge on this multi-week epic.
• An experimental implementation of MSC3383 has been contributed by @Bubu and @jcgruenhage at Famedly, which will help with proxying federation traffic, amongst other uses.
• An experimental implementation of MSC2815 has been merged, which allows room moderators to view redact event content for the purposes of moderation. This was contributed by @tulir at Beeper.
• Device list updates are now asynchronous thanks to Erik, leading to much faster login times for accounts in big rooms.
• plus many other bug fixes and improvements!

We also released a v1.58.1 patch shortly afterwards to address an issue with the Debian packages on some configurations. Server admins not using the Matrix.org Debian packages do not need to install this patch release.

Otherwise, ongoing work from the core team continues with Sean and Rich working on faster room join performance, Olivier pushing forwards on testing Synapse with workers in Complement, while Erik has been tackling general performance work.

Hey folks! We're announcing our 1.6.0 release for matrix-hookshot today. More features in this release: tadzik has gotten involved and given us support for RSS feeds in this release. You can check out how to get going with those in our hosted documentation.

The highlights this time around are:

• Add RSS/Atom feed support (#315)
• Add support for GitLab in the widgets configuration UI. (#320)
• Send a notice when a GitLab merge request gets some review comments. (#314)
• Add new !hookshot gitlab project command to configure project bridges in rooms. See the docs for instructions. (#321)
• New hookshot_connection_event(_failed) metrics for tracking successful event handling. Reinstate matrix_* metrics which were previously not being recorded. (#312)

matrix-appservice-kakaotalk (website)

A Matrix-KakaoTalk puppeting bridge.

Fair announces

This week brings another round of big improvements & new features!

Features & fixes include:

• Fixes to Docker support & the documentation for setting it up
• Changes to the login flow
  • The bridge can now be configured to enforce a login flow that more closely matches the official KakaoTalk desktop client's, and to better warn you when a new login will kick out another one of your KT sessions. This will hopefully prevent the bridge from getting KT accounts banned!
• Backfilling for KT->Matrix read receipts
• Commands for adding/removing KakaoTalk friends
• Commands to edit your KakaoTalk ID & mark it as shared or hidden
• Matrix->KT DM creation, i.e. the ability to create a new DM with a KakaoTalk user from within Matrix
  • This might fail on the first attempt at creating a DM. If it does, try re-inviting the KakaoTalk puppet to the room.
• Many stability & correctness improvements

With the combination of friends list curation & DM creation support, it should now be possible to connect with KT contacts entirely from Matrix! Simply add some friends, list them, and invite a listed friend to a 1:1 room!

Nheko (website)

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

Nico reports

Someone on Twitter complained that no chat client works like MSN anymore, where you could have separate windows for each chat. So for MSN compatibility we added that. (It is a bit experimental still, expect some stuff to not work or crash)

Bulbu also went through a lot of effort to add a second set of emoji shortcodes to Nheko. Those should be more familiar to people coming from other platforms or clients while the old shortcodes are available still as well. We also saw a lot of progress on the Finnish, Chinese, Indonesian and Russian translations, animated images should work properly in the image viewer again, buttons for opening the member list are now clearly marked with a people icon next to them. The memberlist is also now search- and sortable.

Anyway, have a look at how important multiple windows are:

Ement.el (website)

Matrix client for Emacs

alphapapa announces

Ement.el has received several updates since the last time it was mentioned in TWIM:

Additions

• A new room list command, ement-taxy-room-list, shows rooms grouped "smartly" (and programmably). (It will be made the default soon; until then, call the command to use it.)
  • The new room list shows unread-notification/highlight counts, similar to Element.
• Basic support for spaces:
  • Rooms (and spaces) can be added to and removed from spaces.
  • Rooms are listed under their spaces in ement-taxy-room-list.
• Reactions can now be toggled off (i.e. redacted) by clicking them, like in Element.
• Command ement-room-send-file allows uploading non-image files to rooms, and file messages are now displayed usefully, so the files can be downloaded or viewed.
• Command ement-ignore-user ignores and unignores users.
• Command ement-tag-room adds and removes favourite, low-priority, or custom tags on rooms.
• Command ement-room-occur allows searching messages in a room buffer, similar to Emacs's occur command (i.e. it locally searches already-received messages).
• Membership events are now coalesced by default, similar to Element (especially helpful in large public rooms, like bridged IRC rooms, where join/part spam can be overwhelming).
• "In reply to" links in replies, as well as other matrix.to links, can be activated in a room buffer to go to the linked message.
• Mentions in outgoing messages are HTML-linkified (aka "pilled"), like Element.
• Generated avatars for rooms that have none, similar to Element. (Only displayed in ement-taxy-room-list for now.)
• Option ement-shr-use-fonts (disabled by default, which prevents HTML messages from being displayed in a different font).
• Faces for favourite/low-priority rooms.
• Redacted messages that are still known locally are now displayed with a strikethrough (after reconnecting, their content will be unknown).
• When images are disabled, image messages are presented as clickable URLs, so they can still be viewed.
• Some events, like membership events and images, are displayed alongside a vertical bar to help distinguish them from normal messages.
• Even "hotter"-looking timestamps for rooms updated in the last hour.

Changes

• Refactored notification system. Now easier to configure (see M-x customize-group RET ement-notify RET).

Fixes

• Improved error handling when looking up homeserver hostnames and .well-known URIs.
• Improved error handling when processing malformed events.
• "Elemental" display style (not used by many users, apparently).

madlittlemods (Eric Eastwood) reports

In this months demos (also shown off at the top of the TWIM post), Eric showed off a proof of concept to anonymize your screenshots so you can easily include more context when submitting logs or bug reports without worrying where the bug occurred. The current concept will color block all of the text on the page to still maintain the structure of the app but completely hide the content itself.

This still has a ways to go before it's integrated in Element under the click of a button so if anyone wants to take over or give feedback, go comment on the issue, https://github.com/vector-im/element-web/issues/9615. If you want to use the anonymization now, you can manually run the JavaScript snippet from the issue in the browser devtools.

This mode could even be further extended further to include event_id labels in the corner of each message to easily correlate the logs to the screenshot.

Happy screenshotting!

Populus Viewer (website)

A Social Annotation Tool Powered by Matrix

gleachkr reports

Over the last two weeks, the theme in populus-viewer development has been permissions:

1. The settings menu for rooms has been redesigned
2. It's now possible to assign and remove standard roles (admin and moderator) from populus viewer
3. It's now possible to set power levels for standard events and actions from populus viewer
4. It's now possible to ban and unban using the membership management modal
5. Redacting the messages of others is now exposed as an action for those with that permission.

Besides that, I've been having some fun on the css-overhaul branch reorganizing some design elements, and centralizing the color CSS in a few variables, opening the way for things like a dark mode and user-definable themes. Here's a peek at the new milder and more welcoming default look:

Matrix Wrench 0.7.0

I'm working on a few features for Wrench's anniversary on 13th June. Here's a bug fix for storing identities and a new button to check your membership status in a room.

• Added: A "Am I a member?" button tells your membership state in a room.
• Fixed: Unchanged identities got deleted from localStorage when editing identities twice.

Dept of SDKs and Frameworks 🧰

Trixnity (website)

Multiplatform Kotlin SDK for Matrix

Benedict says

After a few release candidates and weeks later, we released Trixnity 2.0.0 today! It contains many breaking changes due to a large refactoring, which allows us to share a lot code between server and client implementations of the Matrix APIs. This means, that Trixnity can be used to implement matrix servers in addition to application services and clients!

Trixnity finally has support for Kotlin/JS. You can implement a browser client or even better: multiplatform client. Support for Kotlin/Native will follow soon (e. g. for iOS clients). Right now, there is no trixnity-client-store implementation for JavaScript (e. g. IndexedDB), so you need to stick with InMemoryStore at the moment.

Besides notification support (push rules are evaluated), we introduced helpers to get the complete timeline as Kotlin-Flow (no more complicated loops to get the timeline). You can even subscribe to all timeline events, which is really helpful to implement bots with e2e encryption support. Speaking of e2e encryption: libolm is bundled into trixnity-olm jars, so you don't need to build olm by your own anymore.

These are the most important features. For the complete changelog, have a look at the release candidates.

Matrix Dart SDK (website)

Matrix SDK written in pure Dart.

Henri Carnot [famedly] announces

This week the team released version 0.9.0 which contains new features and some refactoring as many deprecated endpoints were removed so make sure to use the new ones when doing the migration. Support for the Element recent emoji (io.element.recent_emoji) was added. A new method to get the last read marker was added. Lastly, the timeline logic was enhanced, and it's now possible to load the timeline at a specific event. So you can load the room to the last event and then paginate through the new events. When reaching the last event, the timeline will automatically allow new events to be added in the timeline when received.

See you next week ;)

Dept of Ops 🛠

Cadair announces

I have spent the day ignoring more important things and trying to have something to TWIM. I wrote (yet another) GitHub Action for sending build status to matrix rooms. This action looks at all the completed jobs in your workflow and posts a combined status for the workflow as a message and reactions for all the individual jobs, inspired by the maubot GitLab plugin.

Dept of Bots 🤖

Sundar

Hyperbased in Hyperspace says

Hello together. I made a generic bot, named Safed Sundarata, or Sundar in short, that should make it easy to get basic special functionality working. It has a lot of different functionality so you have an example code to work off of. The main motivation for this bot was to provide an !error <code> command for the developers in the ReactOS Matrix Rooms, which translates error codes to human readable text. Then of course i added other useful or fun commands to the bot. You want to read the Readme to find out more. This is the first time i ever wrote a bot, so feedback and corrections to the Source Code are highly appreciated. It is written in Go using the mautrix-go framework (thanks tulir and everyone who worked on this making it easy!). Even easier is to run and build it with go, no insane build system with broken dependencies required, which was the reason why i made it from scratch.

Mjölnir (website)

The moderation bot for Matrix

Gnuxie 💜🐝 announces

Mjölnir

We have released v1.4.2 of Mjolnir https://github.com/matrix-org/mjolnir/releases/tag/v1.4.2 which includes:

Bot:

• A new JoinWaveShortCircuit protection, thanks to Jonathan with https://github.com/matrix-org/mjolnir/pull/280. This protection can be used to detect a mass-join scenario and set the room to invite-only.
• Change of behaviour: Mjolnir will now apply server ACL and member bans to the most recently active rooms first (while syncing). The order was random before.
• The causes of errors at startup (e.g. via misconfiguration) have been made more clear.
• The image with the latest tag on dockerhub is now correctly in sync with the main branch.

Synapse Module:

• The python module version is now in sync with the current git tag.
• The Readme's example config has been fixed (thanks to Maranda ).

That's all I know 🏁

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

Synapse 1.58 is out! Let's dive into this new release.

Poetry

If you've been reading the past few Synapse release announcements, you might have already heard about our efforts to integrate Poetry into Synapse. Poetry is a tool which manages dependencies of a Python project. Its killer feature is its lockfile, which explicitly pins all dependencies (direct and transitive) to a fixed version, even across multiple Python versions and platforms. See more about why we choose Poetry here.

During the past few months, we've been hard at work converting Synapse and its CI to use Poetry. The goal is to make our Docker images and Debian packages more reproducible and to provide a fixed, known-good environment for CI. This will help us to ensure the stability and security of Synapse installations.

Synapse 1.57's Docker image was the first to use Poetry; after a successful trial, this was extended to Synapse 1.58's Debian packages. Installations from PyPI using pip will not use the locked environment, though everyone is welcome to install from source using our lockfile.

Huge props to David from the Synapse team for leading the work on this front.

Everything else

This release of Synapse also includes performance improvements around sharing device list updates, which should greatly improve login times for large Matrix accounts.

Synapse 1.58 also features the implementation of two MSCs: MSC3383 to include a destination parameter in federation authentication headers, and MSC2815 which (if enabled) allows room moderators to see the content of a redacted event (as long as it hasn't already been deleted by the homeserver).

See the full changelog for a complete list of changes in this release. Also please have a look at the upgrade notes for this version.

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 (in no particular order) Beeper, Dirk Klimpel, Famedly and Sami Olmari.

We've released updates to matrix-appservice-irc and our forked node-irc that it depends on to patch a High security vulnerability. It's advised to update to 0.34.0 as soon as possible.

The vulnerability allows an attacker to manipulate a Matrix user into executing IRC commands by having them reply to a maliciously crafted message.

Incorrect handling of a CR character allowed for making part of the message be sent to the IRC server verbatim rather than as a message to the channel.

If you are currently a matrix-appservice-irc user, exercise caution when replying to messages from untrusted participants in IRC bridged rooms until your bridge instance has been upgraded.

The vulnerability has been patched in node-irc version 1.2.1 and matrix-appservice-irc 0.34.0. You can get the release on Github.

The bridges running on the Libera Chat, OFTC and other networks bridged by the Matrix.org Foundation have been patched.

The vulnerabilities are tracked as GHSA-37hr-348p-rmf4 and GHSA-52rh-5rpj-c3w6.

Thank you, Val Lorentz for reporting this vulnerability.

Matrix Live 🎙

Dept of Status of Matrix 🌡️

Thib says

Taking my GNOME Foundation hat on for this news: the GNOME Foundation is adopting Matrix! Is this TWIM worthy? It probably wouldn't have been if it wasn't for all the great work of Gwmngilfen! We published a joint blog post (though in all fairness Greg did all the heavy lifting) to explain how the decision was taken, and transparently share the data we had at hand.

In practice that means after years of Matrix being around in the GNOME community and being the most popular platform, it's finally moving out of the grey zone of "everyone is using it but some older contributors really like their current set up, so it exists but it's not officially our primary platform". For now we're keeping both our Matrix instance and the bridge to GIMPnet (the IRC network GNOME people have been using for years). The major change is that IRC is now our legacy, so if tradeoffs have to be made Matrix will keep the premium experience.

Again, huge shout out to Gwmngilfen who gave meaning to the data I handed to him.

Dept of Spec 📜

Andrew Morgan (anoa) reports

Spec

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:

• MSC3784: Using room type of m.policy for policy rooms
• MSC3783: Fixed base64 for SAS verification

MSCs with Proposed Final Comment Period:

• MSC3244: Room version capabilities

MSCs in Final Comment Period:

• No MSCs are in FCP.

Merged MSCs:

• No MSCs were merged this week.

Spec Updates

Hello again everyone! Your regularly-scheduled TWIM Spec update has returned, along with graph-based media!

Quick news to point out this week is that a new maubot plugin has been written to simply note the details of MSCs after their IDs ("msc1234") have been posted in a room. The bot supports multiple MSC IDs in a message, message edits, threads and end-to-end encrypted rooms.

A copy of the bot is currently running under @mscbot:matrix.org, so feel free to invite it to a room if you'd find that useful!

Random MSC of the Week

The random MSC of the week is... MSC3216: Synchronized access control for Spaces!

This MSC serves as an alternative to MSC2962, and essentially allows for user permissions to be simultaneously enforced across a set of rooms in a Space. This would allow functionality to users of platforms like Discord, where a user can be a moderator in a guild, and thus in all of that guild's channels.

Dept of Servers 🏢

Synapse (website)

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

richvdh says

A few operational issues have taken up quite a bit of the team's time this week, but we've still found time to cut a couple of release candidates of v1.58. Highlights include:

• Locked python dependencies for our Docker images and Debian packages, thanks to David's poetry work.
• Some big performance fixes, including an optimisation to login from Erik and one to message backfill from yours truly.

We're also excited to see quite a few contributions from outside the core maintenance team: thanks to Dirk, Beeper, Famedly and everyone else in the community who has made pull requests!

Meanwhile on the core team, Sean has been continuing to lay groundwork for faster room joins, and Olivier has been doing some exciting work so that we will (finally) be able to test Synapse in worker mode under Complement.

Dendrite (website)

Second generation Matrix homeserver

neilalexander says

This week we announced Dendrite 0.8.2 with a bunch of usability fixes. As always, join us in #dendrite:matrix.org for more discussion and updates.

Features

• Lazy-loading has been added to the /sync endpoint, which should speed up syncs considerably
• Filtering has been added to the /messages endpoint
• The room summary now contains "heroes" (up to 5 users in the room) for clients to display when no room name is set
• The existing lazy-loading caches will now be used by /messages and /context so that member events will not be sent to clients more times than necessary
• The account data stream now uses the provided filters
• The built-in NATS Server has been updated to version 2.8.0
• The /state and /state_ids endpoints will now return M_NOT_FOUND for rejected events
• Repeated calls to the /redact endpoint will now be idempotent when a transaction ID is given
• Dendrite should now be able to run as a Windows service under Service Control Manager

Fixes

• Fictitious presence updates will no longer be created for users which have not sent us presence updates, which should speed up complete syncs considerably
• Uploading cross-signing device signatures should now be more reliable, fixing a number of bugs with cross-signing
• All account data should now be sent properly on a complete sync, which should eliminate problems with client settings or key backups appearing to be missing
• Account data will now be limited correctly on incremental syncs, returning the stream position of the most recent update rather than the latest stream position
• Account data will not be sent for parted rooms, which should reduce the number of left/forgotten rooms reappearing in clients as empty rooms
• The TURN username hash has been fixed which should help to resolve some problems when using TURN for voice calls (contributed by fcwoknhenuxdfiyv)
• Push rules can no longer be modified using the account data endpoints
• Querying account availability should now work properly in polylith deployments
• A number of bugs with sync filters have been fixed
• A default sync filter will now be used if the request contains a filter ID that does not exist
• The pushkey_ts field is now using seconds instead of milliseconds
• A race condition when gracefully shutting down has been fixed, so JetStream should no longer cause the process to exit before other Dendrite components are finished shutting down

Dept of Bridges 🌉

matrix-appservice-kakaotalk (website)

A Matrix-KakaoTalk puppeting bridge.

Fair announces

The bridge should finally be at "Good Enough" status--and to celebrate, I've bumped the version to 0.2.0 🥳

Features & fixes include:

• KT->Matrix file messages
• Matrix->KT room leaves
  • To leave a KT channel from Matrix, issue the !kt leave command in a portal room.
• Ability to name the virtual "device" for the KakaoTalk login session created by the bridge
  • This makes it easier to distinguish between multiple login sessions of the bridge
• Improvements to KT->Matrix joins, kicks, and admin status
• Many significant stability & correctness improvements
• Docker support
  • This is currently in the testing branch until I can confirm that it works properly

I've also opened a PR to showcase this bridge on https://matrix.org/bridges/ 😃

Ruma (website)

A set of Rust library crates for working with the Matrix protocol. Ruma’s approach to Matrix emphasizes correctness, security, stability and performance.

Jonas Platte announces

Our last update included the words "if things go to plan", and even though that's usually calling for trouble, not so this time! We released Ruma 0.6.0 yesterday and apart from a tiny missing feature that was fixed and released as 0.6.1 today, everything went smooth 🙂

The biggest breaking changes are

• new owned identifier types – calling .to_owned() on &UserId now gives you an OwnedUserId instead of Box<UserId>
• a new event enum hierarchy, where redacted events are better taken into account

Also, with this release we can now claim practically 100% coverage of Matrix v1.2, that is you can send and receive requests for all specified endpoints of the various APIs, as well as send and inspect all specified event types, all with a strongly-typed Rust API.

Aine reports

the Miounne's successor is here - meet Buscarron!

There were no news about miounne for a while because we worked on a new "iteration" that can handle matrix encryption (thanks to the mautrix-go).

So, here is it - Buscarron v1.0.0 with e2e encryption and multiarch (arm32, arm64, amd64) support. It can handle any HTTP POST/HTML form and send it to a (encrypted) matrix room. Of course, Buscarron has small neat features like spam checker and rate limiter.

etke.cc is migrating to Buscarron and deprecating Miounne.

I wrote a small, extensible bot that replays GPX recordings as a location sharing stream. This is an implementation of MSC3489: Sharing streams of location data with history and may help you debug the feature or see it with real world data. Join my Space to see this in action (with the Element Web Labs feature): #geo-trackers:iot-staging.ems.host or run the bot with your own rooms and GPX files. https://gitlab.com/jaller94/matrix-location-sharing

Opsdroid (website)

An open source chat-ops bot framework

Cadair says

Opsdroid 0.26 has been released this week. Included in this release are some improvements to the Rasa NLU parser if you want natural language training for your matrix bots as well as some small documentation improvements to the matrix connector and other bug fixes. Big thanks to Oleg for many of the changes as well as all the other contributors.

Matrix Community Manager (website)

The highly configurable message aggregation and filtering bot for matrix!

Sleuth reports

Matrix Community Manager has seen some work in the features department over the past week.

With the new Ansible playbook I think it's possible for someone with a bit of Ansible experience to get this bot up and running in under 10 minutes. I did a fresh install in 4 minutes. That is a fresh VPS and creating a new matrix account. Instructions for the Ansible deploy can be found here.

The major features are:

• An Ansible playbook that should simplify the installation process for new users.
• Edits to the message that triggered the bot will now be reflected in the bots message. This bot now has a feature Twitter doesn't have :laughing:.
• Hashtags are now called filters. Filters are more customizable allowing for custom delimiters and now show the originating room.
• The AutoJoin feature has filters to control who or from where invites will be excepted.
• Announcements can have more than one output room. Using a comma separated list of room ids.

A few bugs were fixed as well:

• Some text characters were causing messages to be classed incorrectly thus causing crashes.
• Exotic characters specifically in links were causing crashes.

Dept of Servers 🏢

Synapse (website)

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

dmr says

Hello again everyone. This week the team released Synapse 1.57.0, followed by a 1.57.1 patch release that fixed a problem in the 1.57.0 docker image.

This week was a little on the quieter side again, with some of us away on holiday and others away with illness. Nevertheless, this week develop saw a variety of activity. Some personal highlights:

• Shay's effort to document Synapse's numerous config options landed. This is a huge and comprehensive effort that'll help administrators to understand all the options they have to configure Synapse.
• Further progress from Rich on the fast room joins project. In some tests we've seen a 5x speed-up over the status quo!
• A subtle bugfix from Erik which corrects incorrect counts in one of the Admin API endpoints.
• The remainder of the poetry work has landed. There were a few last-minute complications in CI to smooth out, but we've now finished the migration. Synapse's docker images and debian package now come with a fixed set of dependencies (even transitive ones) in a way that lets us support multiple Python versions and interpreters.

We're looking forward to shipping these in Synapse 1.58, whose RC is scheduled for Tuesday the 26th of April.

I'm also keen to see how PR 12522 from Rich and Olivier progresses. It aims to fix a nasty memory bug which can cause Synapse to get stuck in an OOM loop.

As ever, I'd like to express thanks to our community of users, server operators and contributors. Thanks are also due to @callahad: today is his last day of managing the Synapse team. We're all going to miss him and wish him well: thank you for everything you'd done over the last year and a half.

Dept of Clients 📱

Sailtrix (website)

Sailtrix is a matrix client for SailfishOS

HengYeDev says

Summary of development this week

• Sailtrix is fixed on Sailfish 4.4, which added sandboxing to all apps
• Sorting is fixed in the favorites tab
• The create room dialog is fixed
• Some validation is added to the login page
• Sharing with other apps and bluetooth is added for newer Sailfish versions
• SSO seems to be working, still in testing

Element (website)

Everything related to Element but not strictly bound to a client

kittykat announces

Location sharing

• As a follow on from our previous launches, the team is building “live location sharing”. This will allow you to automatically share where you are in the world with others for a period you choose (15 minutes, 1 hour, or 8 hours), instead of sending a single static location.

Community testing

• We ran our first async community testing session this week. Thank you all who joined in! We found 13 issues so far, which is good going.
• We have some new features landing for the search experience on Web, join us for testing from Thursday!
• You can join us at #element-community-testing:matrix.org to find out more!

Element Web/Desktop (website)

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

Danielle says

• Threads is in Beta! The team is hard at work smashing bugs and improving notifications so that we can remove the beta label and get everybody access to our new feature!
  • If you’re using Threads, don’t forget to give us your feedback.
• This week the team discussed how our Web product looks and feels to new users. While we use our own products all the time, it can be good to take a step back and ensure that our product decisions benefit all users, including the newbies. Watch this space for more info in the coming weeks as we continue to trial things that we hope will make onboarding to Element easier.
• In labs (you can enable labs in settings on develop.element.io or on Nightly)
  • Video rooms are coming together nicely, with the addition of lobby screens and room list stickiness to wrap up the design implementation

Element iOS (website)

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

Manu announces

• The newest version of the app (1.8.13) is ready! In this release we’ve made a bunch of improvements and bug fixes, check it out here.
  • Our favourites include: Force touching room previews no longer update your read receipts, there’s a congratulations screen for new users when creating an account, and we’ve reduced the number of home page reloads.
• Also new in product are presence indicators! From your home page or DMs you’ll be able to see if a user is present or away. Note; this is only supported if your homeserver has it enabled.
• Upcoming; We’re working on adding ‘mention pills’ when tagging users in a room.
• Please note; We’ll soon be removing support for iOS 12 and iOS 13

Element Android (website)

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

benoit says

• The team is working on fixing bugs and making improvements to flows like “ignore user”. We’ve also made some changes to the way we format code.
• Element Android 1.4.12 is ready to be released but currently on hold in the Play Store due to rules around User Generated Content (UGC). We’re chatting with Google and the new update should be available soon.

Populus Viewer (website)

A Social Annotation Tool Powered by Matrix

gleachkr says

We've added two major user-facing features to populus viewer:

1. A two-up view in the pdf viewer, allowing you to view and annotate two pages at once on a wider screen
2. An audio viewer, complete with audio annotation, so that you can annotate temporal segments of an audio recording

I'm especially excited about the latter - being able to discuss audio recordings will be a great teaching tool, and I'm hoping it might also be useful for things like people who want to talk about podcasts together (for purposes of editing, or just for fun), and people who want to annotate recordings of public talks of various kinds. The last use case would also be pretty well served by video annotation - so that's now rising on the agenda. I've created an MSC, here where I'll be filling in the details of a proposed format for interoperable audiovisual media annotations. As always, if you've got questions, want to follow development progress, or just want to talk about the future of social annotation on Matrix, come join us at #opentower:matrix.org.

nheko-krunner (website)

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

LorenDB says

nheko-krunner has finally been released! Version 0.1.0 contains several handy features such as searching your rooms, joining new rooms, and starting and switching to direct chats. Furthermore, if a room has unread notifications, nheko-krunner will let you know by tacking on a notification count to the room name (e.g. This Week in Matrix (TWIM) (1). Currently this feature is not disable-able, but I plan to dive into writing KCMs (KConfig Modules) soon so that I can add a toggle for this.

Hopefully a few people find this handy, and remember that if you don't use KDE, nheko still has a handy D-Bus API that you can use to write integrations with other software.

Dept of SDKs and Frameworks 🧰

matrix-rust-sdk (website)

Matrix Client-Server SDK for Rust

Jonas Platte says

Over the last weeks, we've been doing a lot of refactoring in preparation for the 0.5.0 release, but we also

• Added support for retrieving room account data
• Made it easier to create a client while being offline
• Fixed a rare bug with SSO login (localhost didn't always resolve, so we switched to 127.0.0.1)
• We made some progress on sliding sync and adding an FFI interface for the main matrix-sdk crate

Matrix Dart SDK (website)

Matrix SDK written in pure Dart.

Henri Carnot [famedly] says

We haven't done any regular posts about it in a while, but the SDK sees almost weekly releases. (We did release version 0.8.20 last week) If you forgot about it, the Matrix Dart SDK is the SDK FluffyChat, the Famedly clients and a few others use. Let me summarize some of the changes for those who haven't kept up:

One of the killer features is probably WebRTC support 🚀. It handles all the signalling for you, which makes integrating call support into your Flutter or Dart Matrix client fairly simple. Currently it supports version 1 of the call protocol, which is still an MSC and implements a few of the other MSCs. Experiments with group calls are still in progress.

We also switched databases a few times and tuned it more (we posted about FluffyBox last year). The database backend should now be a lot more stable and more performant, while also using less memory.

Continuing with stability, we worked a lot on how the timeline is stored and structured, leading to a much more robust experience. The SDK is also now completely nullsafe 🎉, which gets rid of a lot of annoying error modes. There were some fixes to E2EE here and there, but mostly the experience has been really solid and didn't need much work.

Some of the more recent developments include widget support as well as improving the file upload experience. The SDK now inserts a dummy event for a pending upload, images are thumbnailed and resided in a different isolate and uploads are automatically retried after a connection failure. We are also working on improving the push support, making it easier to fetch events from a push.

And I'm currently working on bringing fragmented timeline support. Nico told me it would be pretty (not) easy to do... and I have to say, he was right. Good first issue 🙃

See you next week ;)

Nix-matrix-appservices

Pacman99 announces

I've created a NixOS module, nix-matrix-appservices, that can simplify the bootstrap and maintenance of matrix appservices on nixos. With it, appservices can be spun up easily with registration and tokens handled by the module. Most mautrix and mx-puppet bridges have been tested to work and they can be setup in a couple lines of nix code. There are plenty of options you can make use of to configure more complex appservices. You can find the the code, matrix room(gitlab badge), and usage information here: https://gitlab.com/coffeetables/nix-matrix-appservices

Synatainer (website)
