(not quite matrix) feneas call for comments on spec for metadata


I'm working on a specification for exporting metadata and usage metrics out of federated servers. The aim is that the same specification could be re-used cross-protocol for example with not only Matrix servers but also ActivityPub, Diaspora and XMPP servers, as an example. Looking for comments here:

Dept of Servers 🏢



Feature Updates

Dendrite continues along with more development from anoa, our resident GSoC student cnly, and a few community members. cnly has been working mainly on fixing up /sync issues and other areas of the CS API, fixing the various federation issues, mainly those dealing with room state, and various other maintenance tasks around the codebase that are highly appreciated. peekay_46 has been hard at work completing Dendrite’s implementation of room tagging and trion129 returned to continue with adding a fallback page for recaptcha (for clients that can’t render web pages). We have a number of community PRs still with active members, but most are waiting for reviews, which anoa is working towards.

The Plan

A couple TWIMs ago we teased that Dendrite had a plan in the works. Well one meeting later and here is the proposal:

It will take a while for Dendrite to become feature complete with Synapse, but we’d like people to be able to actually use Dendrite before then. Instead of waiting for feature-completeness, we propose a set of milestones for Dendrite development to reach and prioritize development for.

These milestones are currently listed on Dendrite’s github. The first is “Bot Hosting”, which means, once complete, Dendrite would be suitable as a “bot hub”, allowing server admins to run massive bridges on top of Dendrite while taking advantage of its horizontal-scaling capabilities. As written in the description, this goal includes basic CS API support, as well as federation with other homeservers. At this stage Dendrite should already be usable in rooms with other Synapse servers, which should make it a lot more interesting.

After that is several more milestones, each representing another use case that Dendrite can fill.

Don’t be alarmed at the currently quite small percentage of completeness, as these milestones have just been built from the open issue list. We’re actually quite far along to #1 already :)

We also want to mention that the milestones aren’t completely built yet - there’s still a few more issues to comb through. It’s taken a few days as anoa can’t help himself to fix things as he goes along. A few open issues have also been closed as they had already been fixed earlier.

This is all mentioned in this week’s Matrix Live above by the way, so be sure to catch for some extra details if you’re interested.

We look forward to shipping you a working Dendrite soon™. And as always feel free to join us in for discussion.


Neil, who oversees the Synapse factory:

This week we’ve been working on improving database performance, shipping the new small hosted homeserver instances - expect a lot of improvements to come that will benefit the whole community and merged our recent OpenTracing support. We’ve also made some changes to how Sydent processes and stores email - more details here

Next week, expect a new release, more database performance improvements and general Synapse performance work.

Listen to Matrix Live to hear Erik talking about his DB perf work ☝️


This Week in Ruma, from Jimmy:

While I was working on ruma-signatures, I decided to fill in the missing functionality—signing and verifying events. In the process of doing that, I ended up with a significantly revised API for the crate, which has now been released as version 0.5.0.

Dept of SDKs and Frameworks 🏗

New release of matrix-nio (Python SDK)

poljar said:

New matrix-nio release bringing you documentation improvements across the board, while the documentation is still not fully complete yet it should be much easier to get started with nio.
Another highlight of this release is couroutine support for the event callbacks for the AsyncClient.

Take a look at the getting started guide too.

Ruby SDK


I just cut a 1.3.0 release of the Ruby SDK, mainly focusing on solving an issue due to Ruby extensions polluting the global scope. It also adds a very slightly extended response handling, which recursively adds getters for the keys of the resulting objects.
Many thanks to the people reporting issues to me so I can keep improving the SDK.

The Kotlin library koma

yuforia, author of koma and Continuum:

  • Fixed incorrect type casting in function
  • Reorganize the structure of modules, separate APIs that don't require authentication, so that they can be used before signing in

Dept of Bridges 🌉


Half-Shot announced:

Today we've released 0.3.0 of the slack bridge since the last rc has proved to be stable. I hope you all enjoy the new features we've packed into this release. And as a reminder, there is another release right around the corner :)

Dept of Clients 📱

RiotX (Android)

From the team (see Matrix Live from last week for more from them):

  • RiotX 0.2.0 has been released on Thursday. Main new features: room filtering, mesage editing in e2e rooms, view editing history. Also many small new features and bugfixes.
  • The team is still working on the main missing features: creation of direct chat, read receipt, along with UI/UX polishing.

If you're using Android, definitely start trying RiotX, you can even find it in the Play Store now.

Riot Web

From the team:

Riot v1.3.0 was released with support for reactions and message editing enabled. Check out the Riot blog post for more details. No changes are needed to enable these features for self-hosted installs anymore (which is change from what was stated in last week’s TWIM update).

We’re continuing to work on several privacy improvements to related to integration managers and identity servers to give users more control over these.

Riot Android

From the team:

Riot 0.9.2 has been released on Friday. It contains some bug fixes and new translations for many strings especially for the device verification feature.

Riot iOS

From the team:

  • We released v0.9.1 with message editing, reactions and file upload.
  • We are continuing to work on reactions (emoji picker).
  • We have started to implement soft logout.



In the newest update FluffyChat now supports avatars in Push Notifications. Also translations have been updated and some minor design tweaks have been made.

I know that E2EE for FluffyChat is continuing to be worked on, just not quite ready yet.

Continuum, client based on koma

yuforia, author of koma and Continuum:

  • Update GUI library openjfx from version 11 to 12
  • Rewrite build script in Kotlin, replacing Groovy

Fractal, GNOME client

Alexandre Franke on Fractal:

Several bugs were fixed in the past three weeks. We are also sending typing notifications now. With 4.1.1 out, we’re at the second beta on the way to 4.2.


some people might be interested in a tweak in our build config that makes it so that crashes are aborts now (i.e. you get a trace and they are not silent anymore)


Black Hat is changing Spectral's buildsystem from QMake to CMake.

Dept of Ops 🛠

sendtomatrix script

Madic has created a shell script to send messages to a room:

I've written a linux shell script with which you can send (multiline) messages to a matrix room. It only needs a username / password or access token, server fqdn and roomid as argument or provided by a configuration file. Arguments can overwrite settings from the file, for e.g. using same credentials but different channel. If no access token is provided, a new one will be requested and used to send the message. You can use the script for e.g. cronjobs, nagios notifications or ci pipelines. An example for a cronjob and a nagios notification script is also provided.

shell script nagios

I have ended up with an similar file of my own containing a bunch of commented-out curl lines, but this is a lot cleaner!

You may also recall a similar project: matrix-shell-suite (

Dept of Bots 🤖

Maths bot(s)

Tim created a bot for rendering Maths:

I was told that people here might be interested: I just wrote a small bot that can reply with PNG renderings of maths (

and then, tulir blatantly ripped him off was inspired to create a maubot providing the LaTeX to SVG rendering:

Privacy Changes to New Vector Identity Servers

2019-07-19 — Privacy — Thomas Lant

As a step towards implementing Terms of Service for Sydent Identity Servers (MSC2140), we're rolling out a couple of changes to the two Identity Servers run by New Vector (running at and

  1. We have erased all of the data where there is any chance that the data subject didn't understand how, why or with whom their data was being shared.
  2. We've made a change to Sydent so that it no longer persists new associations relating to users on homeservers not run by New Vector.

The impact of these changes is that users on homeservers not run by New Vector will no longer be discoverable by their email or telephone number via the Identity Servers running at and As we roll out the rest of the changes for Terms of Service for Identity Servers, this functionality will again be made available for users who make an informed choice to opt in.

Registration with Email and Password Reset

In the short term, the New Vector Identity Servers will continue to support registration with email (signing up with an email address as well as a matrix username) and password reset. However, as we continue to improve Identity Server data hygiene practices, we will phase out their use in registration with email and password reset entirely. We have already made the change to Synapse to support password reset without relying on an Identity Server (though this can optionally be re-enabled).

Once Synapse can support registration with email without relying on an Identity Server we will announce a schedule for disabling registration with email and password reset in our Identity Servers entirely. After this point, homeserver administrators will have to make sure their homeservers are configured to send email to keep registration with email and password reset working. More details on this to follow - please watch this space.

5-user Matrix homeserver hosting now available from Modular

2019-07-17 — General —

Hi all,

If you’ve been looking for a way to have you own Matrix homeserver without having to run it yourself, you may be interested to hear that Modular (the Matrix hosting provider run by New Vector, the startup which hires many of the Matrix core team) is now offering a personal-sized small homeserver hosting service, supporting a minimum size of 5 user servers.

A lot of recent performance work on Synapse has been driven by the need to make smaller dedicated servers more efficient to run - and so if you run your own homeserver you’ll be benefiting from all this work too :) Meanwhile, if you choose to outsource your server hosting to Modular, you’ll be indirectly supporting core Matrix and Synapse development, given most of the core Matrix team work for New Vector - it’s through buying services like this which lets us keep folks able to hack on Matrix as their day job.

See more details over at the Modular blog post!

Matrix Live: RiotX

Nice! Manu and Benoit, who work on the Riot Mobile, discuss the development status of RiotX.

Dept of Servers 🏢


A bit of everything this week, we’ve made changes to support the upcoming edits and reactions release, worked on soft log out, experimented with improving general perf for small homeservers, landed open tracing support, improved db query load.
Next week we’ll see about landing the small homeserver perf improvements, work on id hashing in sydent, fix some e2ee bugs (made easier to track down with OpenTracing), do some more database performance work and start gradually rolling out the new Sygnal instance.


Jason back on it:

This week in Matrix, Construct made the crazy-loading mode of client sync the default. Crazy-loading is an approach to initial sync that goes beyond lazy-loading for a better UX. It's even backwards compatible with clients that don't support lazy-loading.

Construct also made significant progress on implementing version 3 and 4 rooms during the week. This is nearly complete, and should be ready for testing by the weekend.

Good to know there is progress with new room versions as more and more rooms start to be moved over to v4. for testing and more info.


This week we’ve implemented profile retrieval over federation, single event retrieval, room tagging as well as host of bug fixes.
Next week we’ll be looking at state resolution and implementing our latest and greatest algorithm needed by modern room versions.

This Week in Ruma

Jimmy provided This Week in Ruma:

Work continues on the major revamp of ruma-events mentioned in the last update.
There are also a few modules that are somewhat blocked on an issue in ring. Some of the types in ruma-events contain types from ruma-signatures which don't implement Clone and PartialEq because they contain types from ring which don't.
Rust 1.36 was released, and it includes stabilization of the Future trait, one of the long-awaited building blocks for first-class async support in Rust. [...] the biggest reason for Ruma's development hiatus is waiting for async networking in Rust to mature, and this is one of the final pieces of foundational support we've been waiting for. The remaining pieces are async/await syntax, which is expected in either the next version or the one following it, and finally, waiting for important libraries like Hyper and Tokio, as well as web frameworks, to adopt the new stuff.

libQuotient gets .well-known support


Thanks to Black Hat, libQuotient gained support of .well-known - a very useful feature to connect to Modular-hosted homeservers!

Also, the first block of E2EE functionality from aa13q has been merged to libQuotient master - so far it's just uploading the keys but receiving messages is already well in the works!

Dept of Bridges 🌉

mautrix-telegram v0.6.0


mautrix-telegram v0.6.0 was released. Recent changes include bridging strikethrough, underline and nested formatting to telegram and some bug fixes, including one security fix. Full changelog on GitHub.

Debian 10 was also released recently, which means v0.6 is the last version with Python 3.5 support. Starting from v0.7.0, mautrix-telegram will only support Python 3.6 and up.

mautrix-telegram v0.6.0 also includes Native Matrix edit support, message editing between platforms.

matrix-appservice-slack 0.3.0-rc2

Half-Shot and the Slack-bridge-gang have announced matrix-appservice-slack 0.3.0-rc2

Hi folks, the slack bridge has had another RC release this week 0.3.0-rc2 which has been deployed onto :). In other news, we are nearly done with the port of the bridge to Typescript (slated for the 0.4 release) which has allowed us to clean up the codebase significantly and splat a lot of bugs.

I'm for any movement toward TypeScript - seems to be a winner in the JS-world. Says Half-Shot:

I'm a bit fanatical about Typescript, it's objectively better to write things in TS than JS if you have the freedom to do so. It's also allowed us to keep the bug count down on the Discord bridge, so I'm starting to look at the other bridges for typescript support too.

Reliable Bridges GSoC project 🎓

Thanks Kai for this update!

The new Spec proposal MSC2162: Signaling Errors at Bridges landed! It is about adding permanent errors: The ability of bridges to mark events as not delivered to all participants. While there is already code supporting the feature, the Spec process is important for getting everyone on board and finding potential problems with the current approach.

In spite of being a relatively small proposal, there were already a lot of suggestions and directions in which it can evolve. Shoutout and thanks to everyone who already contributed to it with their comments!

Meanwhile on the more practical front a fork of Riot Web was extended to now support the actual visual display of bridge error markings on messages.

See it in action:

Dept of Clients 📱

RiotX big announcement!

I've been using RiotX a lot lately and find it great - really snappy.


Black Hat:

Spectral supports .well-known now obviously. see libQuotient update above
Also a lot of changes:

  1. Bubble shapes for pending events are fixed.
  2. You can set device name when logging in. This becomes important as libQuotient begins to upload one-time device key as part of E2EE implementation.
  3. Markdown is parsed automatically by default, and works with replies.
  4. Small UI improvements in timeline and room list.


yuforia has continued work on Continuum, a desktop client written in Kotlin:

Continuum now preserves media content URI (mxc://) internally in order to treat them specially, instead of converting to all URI to http (or https) upon receiving.
This week's version never considers cached mxc resources stale and no network request will be performed for refreshing.
Continuum also loads previews for http image links in text messages automatically. The usual http cache control rules are still followed in those cases.

Join to chat more about Continuum, or about koma, the underlying library.

Riot Web

Riot v1.3.0-rc.1 is now ready for testing at This includes some last minute polish of reactions and edits, and also adds initial support for soft logout. This release will have reactions and message editing enabled via configuration on once it stabilises.
Self-hosted installs that wish to do the same would need to alter their config.json in similar fashion. This is because these features currently depend on unstable APIs, and we don't want to move them out of labs and fully on by default until that is resolved.

Riot iOS

  • Reactions and edits:
    • Enabled by default (no more LABS setting)
    • Reactions with non-unicode keys
    • Original event in the edit history (need homeserver update)
  • Upgraded rooms are now autojoined when tapping on the upgraded banner
  • File upload from the room screen and from the share extension
  • Crypto: logs have been improved and a script has been created to help to debug e2e bugs (see the screenshot at
  • This Friday TestFlight can be considered as a release candidate

Dept of Ops 🛠

matrix-docker-ansible-deploy: synapse-janitor now available


Thanks to Aaron's frequent mention of synapse-janitor and other such cleanup methods, I've finally gotten inspired enough to give it a try.

The playbook now contains a new Synapse Maintenance documentation page and an easy/safe way to run synapse-janitor.

To give an example, using synapse-janitor and a full Postgres VACUUM yielded a 29% reduction in disk space used by Postgres on my personal homeserver (5.3GB -> 3.8GB).

Alexey Murz Korepov also reminded us about synapse-purge, which we've mentioned here before - but is designed for a similar purpose.



the avhost/docker-matrix image has moved to a debian buster base image, which got us an upgrade from python 3.5 to python 3.7.3 and jemalloc1 to jemalloc2, which should improve the performance of synapse.

Dept of Articles 📝

Pneumaticat: "wrote a blog post on integrating Riot chat with our dapp & scientific research auditing platform, Delphus!"

Final thoughts 💭

I had/stole the idea to create a bot which uses message edits to send frames of an ASCII-art animation. I indeed created the bot, which works to a degree, but is quickly punished by rate-limiting, which limits the effectiveness. Still it's quite fun, you can check out the code here.

TravisR's work on matrix-js-bot-sdk is interesting for bot or other client devs, and there is a new guide available:

A few weeks ago I mentioned matrix-enact, which uses Web Audio API to play back room history. There is a guide to how it was built, looking at the /context endpoint now available:

Half-Shot "bridged to #matrix-synapse on freenode to help folks who might be experiencing issues with their homeserver and need a IRC based support channel"

Black Hat made a cool-looking thing: "It basically shows all pictures in this room in a waterfall, with 'infinite scroll'"

Movement on Matrix URIs

Sudden interest in matrix-org/ means we're getting a lot closer to agreement on Matrix URIs. Kitsune even added support for them in Quaternion (see below).

Dept of Servers 🏢



Dendrite continues marching forward! As more attention is turned towards our fairly lengthy PR list, contributors who have not done so already are reminded to merge Dendrite's master branch into their PRs, as converting the project to go modules caused a lot of conflicts. A tag has been added to each PR that needs forward merging, visible here.

Our GSoC student cnly has been working away on implementing profile retrieval over federation as well as updating his various other PRs and would likely have a lot more if they were getting more reviews, but worry not as things look on track for that next week.

We've also got plans now! Plans for how to properly ship this thing over the coming months so look out for that soon!

Synapse 1.1.0 released

This week we shipped v1.1.0, which provides an overhaul of docker configuration, more authentication options and improved db io. It’s worth noting that v1.1.0 is the first Synapse release to drop support for Python 2 (and Postgres 9.4), this paves the way for using Python 3 only functionality.

We’ve been working on supporting soft logout, more edits and reactions support, open tracing support not to mention a complete rewrite of the push server Sygnal. We’ll be rolling out new Sygnal gradually over the next week or two.

Finally, aided by dropping Python 2 support, we’ve been putting in a bunch of work to improve Synapse in resource constrained environments. This will be a constant theme over the coming months.

Dept of SDKs and Frameworks 🏗


Brian Ó appeared to tell us about python-matrixbot. This is a project that has existed for some time.

A Python module meant to act as a base class for a Matrix bot.
The MatrixBot class will connect to the Matrix server, start a listener on each joined room, and listen for room invites from other users. It also includes helper methods you can use to extend the functionality. It is built on the Matrix Python SDK which can be directly accessed via MatrixBot.client



koma got some improvements, based on what's learned developing Continuum, which is a desktop client based on it.

  • Make api calls suspendable functions (which are like Kotlin's flavor of async). This way, the caller don't need to worry about forgetting to call await or a coroutine being left unstarted.
  • Borrowing from functional programming, model the outcome of a call as a discriminated union, which can be either a success or a failure. The successful case is optimized with inline classes, an experimental feature in Kotlin 1.3, and wrapping is avoided.
  • Make MatrixError a subclass of HttpError, because the http status code can be handy

Ruby SDK


Just released version 1.2.1 of the Ruby SDK, fixing an error in the media download URL generation

Dept of Bridges 🌉

matrix-appservice-bridge release 1.9.0

Half-Shot was seen to exist IRL this week, he also found time for a new release:

Today we have a new matrix-appservice-bridge release 1.9.0. The bigname feature this week is a new store for mapping matrix events to remote ones, so bridges can handle changes made to sent events like reactions/threading/edits/redactions :). The reason for this feature appearing suddenly will become clear very soon.. 😈

mx-puppet-bridge (inc slack, tox, discord)

Another week, which means more work on the mx-puppet-bridge ecosystem! A new > bridge has been added, mx-puppet-discord. Soru finally added license files > (Apache-2-0) and some readmes.


  • bugfixes
  • implement optional double-puppeting (also logging into your matrix acc)
  • relate remote event IDs to matrix event IDs
  • handle edits in both directions
  • handle redactions in both directions
  • initiating conversations from matrix! Invite a ghost for 1:1 or follow a > room alias for rooms
  • bot provisioning: list users and rooms


  • add linting
  • map channels and slack pills
  • handle message edits
  • handle message deletions
  • properly handle /me messages
  • handle ghost invites
  • handle room joins via alias


  • add linting
  • improve bootstrapping
  • improve file transfers
  • handle ghost invites


This is the new puppeting bridge! The idea is that, in the long run, this will > be run in conjunction with matrix-appservice-discord Half-Shot/matrix-appservice-discord), where mx-puppet-discord handles DM > puppeting and matrix-appservice-discord the remaining. For this, the message > parsing was split in a new repository, matrix-discord-parser. The idea is that, in the > future, when inviting a ghost on matrix-appservice-discord it'll initiate > conversation within mx-puppet-discord

  • basic text messages
  • handle files
  • handle edits, deletes

mx-puppet-discord does only DMs, for non-DMs please use matrix-appservice-discord

If you have any questions for any of these, please join our channel > Software doesn't write itself, please consider > donating on liberapay!


Cadair and Half-Shot have been doing substantial work on matrix-appservice-slack.

We've got a dedicated room for slack bridge development over at, since it's picked up in terms of community PRs and general interest. It's not currently being used as a support room, however.

They mention,

warning may contain ranting about the codebase

But that could be any room, so it seems ok to me.


Hi everyone! Myself and Cadair have been working hard on a new Slack bridge release, and we are finally ready to push out a release candidate for 0.3.

The headline features are:

  • Implement message deletion.
  • Add support for edits.
  • Add support for reactions.
  • Add support for threading (using replies).
  • Support displayname and avatar lookups for Slack bots.
  • Replace channel mentions with canonical aliases for bridged rooms.
  • Support for slack attachments (Thanks @umitalp for the inital groundwork and @Cadair for the cleanup)

The new release is having very final minute checks, and will be avilable at shortly.

Dept of Clients 📱

What to expect in the next release:

  • Fix timeline jump issues
  • Remove redundant state messages when a room is upgraded
  • Start work on chat details screen (members, change name, etc.)

Quaternion now with Matrix URI support


to push things forward on Matrix URIs front, Quaternion master branch now supports matrix:user/userid, matrix:room/roomalias and matrix:roomid/roomid URIs. For example, Quotient/Quaternion room can be opened by a link matrix:room/

This will be so much easier to use! Also:

Quaternion has got a new contributor, Roland Pallai (, who added colouring of messages sent by the local user and support of drag-n-drop of text and images on Quaternion, along with general improvements on the timeline. Many thanks!

Windows builds of Quaternion (CI and future releases) come with Qt Keychain enabled, storing your access tokens in Windows secure storage.

Spectral news

Black Hat:

A lot of improvements have been added to Spectral last week.

  1. Spectral uses QtKeychain now. Access tokens are stored in system keychain instead of in plain text.
  2. Room list's filter has a better UX(aka TabBar). Switching between rooms and DMs is now as easy as switching between, well, tabs.
  3. Notification count in system tray icon, implementation modified from nheko.
  4. Display initial sync progress. Some people have been complaining about not knowing the progress of initial sync so I added an indicator.
  5. A better room setting page. Specifically displaying aliases and changing room avatar are working.
  6. Big emojis.
  7. Typing indicator UI is tweaked and looks better.

Riot iOS

  • Reactions in e2e rooms
  • “Show all” button when there are too many reactions
  • Support edition of emotes and replies
  • Edits history (even in e2e rooms)
  • Fix joining new upgraded room through federation
  • Use via parameters to join a new room (useful in case of federation)

Riot Web

  • Allow resending edits, reactions and redactions through context menu, also better visualization of send errors.
  • Allow redacting and viewing source of edits in edit history dialog

Bumped the K8s optimized Docker image to 1.1.0, with the same dropping of Python 2 and Postgres 9.4 support as the official image.
NB: The upstream docker configuration changes do not affect the K8s-optimized image, no configuration change is necessary to upgrade from 1.0.0 to 1.1.0

avhost/docker-matrix image


As announced last week, with the release of synapse 1.1.0 the avhost/docker-matrix image switched to running synapse with jemalloc by default

Dept of Services 🚀 starting to make Small instances available are making the much-asked-for SMALL instances available. This service is rolling out starting with people who have previously enquired about availability, which I gather is a lot of people. Go sign up if you're interested!

we've been working on a v1 admin dashboard for managing your Synapse instances through Modular. This is now live on the site and provides a basic suite of functionality including:

  • Viewing users of your synapse homeserver(s)
  • Creating users
  • Deleting users
  • Resetting user passwords
  • Viewing user profile and server access / activity
  • Sending messages to all system users as the system alerts user
  • Information about the synapse instance versions

Final thoughts 💭

Ananace is "continuing the rewrite of the release tracker project. Working towards getting it to only store state in Matrix so it can be run in a read-only environment like a K8s deployment."

lino "wrote a script to update riot. It also works so far, but still needs some improvements"

Black Hat has been working "to add .well-known support for libQuotient" - presumably this will come back to be used in Spectral when it's ready.

Somehow I had a tab open with a maubot for Urban Dictionary.

That's all I know 🏁

See you next week, and be sure to stop by with your updates!

Synapse 1.1.0 released

2019-07-04 — General — Neil Johnson

Right folks, this is our first post 1.0 release, which means that we have now officially dropped support for Python 2 and Postgres 9.4. This means that we can start making use of Python 3 specific features and you should expect lots of associated performance wins over the coming months. See the upgrade notes for more.

Synapse 1.1.0 also contains a reworked approach to the Docker image, as well lots of performance improvements with special focus on DB IO - expect more to come in this area.

Special thanks to community member Alexander Trost for rounding out our SAML support and also to Daniel Hoffend for contributing the ability to disable local password authentication.

As ever, you can get the new update here or any of the sources mentioned at Note, Synapse is now available from PyPI, pick it up here. Also, check out our Synapse installation guide page

The changelog since 1.0.0 follows:

As of v1.1.0, Synapse no longer supports Python 2, nor Postgres version 9.4. See the upgrade notes for more details.

This release also deprecates the use of environment variables to configure the docker image. See the docker README for more details.

No changes since 1.1.0rc2.

Synapse 1.1.0rc2 (2019-07-03)


  • Fix regression in 1.1rc1 where OPTIONS requests to the media repo would fail. (#5593)
  • Removed the SYNAPSE_SMTP_* docker container environment variables. Using these environment variables prevented the docker container from starting in Synapse v1.0, even though they didn't actually allow any functionality anyway. (#5596)
  • Fix a number of "Starting txn from sentinel context" warnings. (#5605)

Internal Changes

  • Update github templates. (#5552)

Synapse 1.1.0rc1 (2019-07-02)

As of v1.1.0, Synapse no longer supports Python 2, nor Postgres version 9.4. See the upgrade notes for more details.


  • Added possibilty to disable local password authentication. Contributed by Daniel Hoffend. (#5092)
  • Add monthly active users to phonehome stats. (#5252)
  • Allow expired user to trigger renewal email sending manually. (#5363)
  • Statistics on forward extremities per room are now exposed via Prometheus. (#5384, #5458, #5461)
  • Add --no-daemonize option to run synapse in the foreground, per issue #4130. Contributed by Soham Gumaste. (#5412, #5587)
  • Fully support SAML2 authentication. Contributed by Alexander Trost - thank you! (#5422)
  • Allow server admins to define implementations of extra rules for allowing or denying incoming events. (#5440, #5474, #5477)
  • Add support for handling pagination APIs on client reader worker. (#5505, #5513, #5531)
  • Improve help and cmdline option names for --generate-config options. (#5512)
  • Allow configuration of the path used for ACME account keys. (#5516, #5521, #5522)
  • Add --data-dir and --open-private-ports options. (#5524)
  • Split public rooms directory auth config in two settings, in order to manage client auth independently from the federation part of it. Obsoletes the "restrict_public_rooms_to_local_users" configuration setting. If "restrict_public_rooms_to_local_users" is set in the config, Synapse will act as if both new options are enabled, i.e. require authentication through the client API and deny federation requests. (#5534)
  • The minimum TLS version used for outgoing federation requests can now be set with federation_client_minimum_tls_version. (#5550)
  • Optimise devices changed query to not pull unnecessary rows from the database, reducing database load. (#5559)
  • Add new metrics for number of forward extremities being persisted and number of state groups involved in resolution. (#5476)


  • Fix bug processing incoming events over federation if call to /get_missing_events fails. (#5042)
  • Prevent more than one room upgrade happening simultaneously on the same room. (#5051)
  • Fix a bug where running synapse_port_db would cause the account validity feature to fail because it didn't set the type of the email_sent column to boolean. (#5325)
  • Warn about disabling email-based password resets when a reset occurs, and remove warning when someone attempts a phone-based reset. (#5387)
  • Fix email notifications for unnamed rooms with multiple people. (#5388)
  • Fix exceptions in federation reader worker caused by attempting to renew attestations, which should only happen on master worker. (#5389)
  • Fix handling of failures fetching remote content to not log failures as exceptions. (#5390)
  • Fix a bug where deactivated users could receive renewal emails if the account validity feature is on. (#5394)
  • Fix missing invite state after exchanging 3PID invites over federaton. (#5464)
  • Fix intermittent exceptions on Apple hardware. Also fix bug that caused database activity times to be under-reported in log lines. (#5498)
  • Fix logging error when a tampered event is detected. (#5500)
  • Fix bug where clients could tight loop calling /sync for a period. (#5507)
  • Fix bug with jinja2 preventing Synapse from starting. Users who had this problem should now simply need to run pip install matrix-synapse. (#5514)
  • Fix a regression where homeservers on private IP addresses were incorrectly blacklisted. (#5523)
  • Fixed m.login.jwt using unregistred user_id and added pyjwt>=1.6.4 as jwt conditional dependencies. Contributed by Pau Rodriguez-Estivill. (#5555, #5586)

Updates to the Docker image

  • Add ability to change Docker containers timezone with the TZ variable. (#5383)

  • PostgreSQL 9.4 is no longer supported. Synapse requires Postgres 9.5+ or above for Postgres support. (#5448)
  • Remove support for cpu_affinity setting. (#5525)

  • Improve email notification logging. (#5502)
  • Fix "Unexpected entry in 'full_schemas'" log warning. (#5509)
  • Improve logging when generating config files. (#5510)
  • Refactor and clean up Config parser for maintainability. (#5511)
  • Make the config clearer in that email.template_dir is relative to the Synapse's root directory, not the synapse/ folder within it. (#5543)
