Matrix Live - Prof. Jon Crowcroft, Foundation Guardian 🎙

Matthew & Amandine talk with Prof. Jon Crowcroft, one of the new Matrix.org Foundation Guardians!

Matrix 1.0

The big news this week is that we declared ourselves to be out of beta. You'll want the full post for all details, but here's a taste:

We are very excited to announce the first fully stable release of the Matrix protocol and specification across all APIs - as well as the Synapse 1.0 reference implementation which implements the full Matrix 1.0 API surface.

This means that after just over 5 years since the initial work on Matrix began, we are proud to have finally exited beta!! This is the conclusion of the work which we announced at FOSDEM 2019 when we cut the first stable release of the Server-Server API and began the Synapse 0.99 release series in anticipation of releasing a 1.0.

As part of the 1.0 we also announced the Matrix.org Foundation.

For the full update on the Foundation, please check out the new website content at https://matrix.org/foundation which should tell you everything you could possibly want to know about the Foundation, the Guardians, the Foundation’s legal Articles of Association, and the day-to-day Rules which define the Open Governance process.

Thanks to everyone who has stuck with us along the way to make this possible.

Synapse

We released Synapse 1.0.0 this week to coincide with Matrix 1.0. As a release Synapse 1.0.0 focuses on security and stability which in turn builds a firm foundation for the performance improvements that you can expect to see over the Summer. Read all about it here.

Crypto

We have not one but two working end to end demos of device cross signing! This is going to be huge and is key step towards being able to make Matrix e2ee by default.

Cross Signing Demo

Additional Treats

But wait there's more! Pantalaimon not only provides a way for clients and bots to participate in e2ee rooms, it now provides the ability to search. Checkout this (religious themed) demo.

Pattle

Pattle is going great guns at the moment. Here's Wilko:-

A new version of Pattle has been pushed to F-droid!

• Add ability to create group chats!
• Show chat creation events ('Wilko has created this group')!
• Show emote messages correctly!
• Handle display name changes! Display names of messages will now be as they were at time of sending.
• Don't show invite and join events in direct chats This is only happens for the two initial users in the direct chat. If someone invites someone else to the direct chat (trough another client), the invitation will show up in the timeline.
• Use the timeout parameter while syncing. This means that receiving new messages should be way quicker! (Thanks Mathieu!)
• Store messages retrieved remotely (thanks Mathieu!) This means that scrolling up in a chat will be faster now, because the messages are cached.
• Always show a date header above the oldest event
• Show replies correctly in chat overview
• Show sent state icon next to own message in chat overview
• Show newly joined rooms at the top in the chat overview
• Use a bit bolder font for chat names in overview To install this release, add the following repo in F-droid:

https://fdroid.pattle.im/?fingerprint=E91F63CA6AE04F8E7EA53E52242EAF8779559209B8A342F152F9E7265E3EA729

And install 'Pattle'.

Or download the APK from the link.

If you stumble upon any issues, please report them! You can now login via GitHub and Gitlab.com , so it's really easy to do!

Follow development here: #app:pattle.im!

There is now also a room for the Matrix Dart SDK (which is being developed for Pattle): #sdk:pattle.im

If you would like to support me, you can now do so via Liberapay and Patreon.

RiotX (Android)

• Crypto has been merged to develop \o/. We are still working on the feature, for the remaining actions: delete device, export and import keys, keys backup / SAS UI polishing, cleanup keys when signing out, and also fixing bugs…
• A new screen has been added to create Rooms.
• Animation of the Floating Action Button on the catchup screen has been improved.
• Valere has started to work on notifications.
• François is working on migration to Dagger2 (instead of Koin). It should improve performance and will allow us to implement multi-account support(!)
• Copyright, Term and conditions, privacy policy and third party license screens are coming soon.
• Progress indicator on Home for initial/catchup sync is coming soon as well.

Riot Android

• Fix issue on SAS, to allow cross-signing.

Riot iOS

• Work continues on edits and reactions - we'll have something for you very soon ...

Riot Web

• Editing now supports editing unsent messages(!!), editing emotes, and lots of polish
• Reactions now instantly cancel when you redact them
• Redactions now instantly redact when you send them
• Released v1.2.2-rc1 (up for testing at https://riot.im/staging/) - this release includes room breadcrumbs being out of labs, some fixes for inviting by email, fixes uploads in chrome canary / firefox nightly, config file validation, some fixes for the new emoji font and lots of other bug fixes.

Ruma

Jimmy reports that

New versions of the ruma-api and ruma-api-macros libraries were released, and work is underway to bring ruma-events up to date with client-server spec r0.5.0

Media

TravisR has this to say: >Both matrix-media-repo and Dimension have been updated to handle federation certificates. Please update, as you would for Synapse 1.0.0

Fractal

Alexandre Franke has fixed the regression he found last week. The team also did a bit of housekeeping with a few dependency updates.

Misc

Half-Shot reports that:

I wrote a bot to control ansible playbooks https://github.com/Half-Shot/matrix-ansible-bot. I'm informed such a thing already exists as an ansible module, but I failed to realise that and wrote a independent one in TypeScript.

tulir reports that:

I made a simple reminder maubot: https://github.com/maubot/reminder It's available at https://matrix.to/#/@reminder:maunium.net

For room admins wondering if they can upgrade their rooms to v5, I made a bash script that checks all the servers in a room and prints a nice summary of the number of servers and members on each version: https://gist.github.com/tulir/aa2df287a0d192b86e5b675687791d16

Atreatis reports that:

Currently grin is building a backend for matrixservers.net that will collect data and push statistics every hour to our website. Next to that I wanted to push forward that me and several others are looking into building a Code of Conduct that should help every new and existing home server. This code of conduct will be build and curated from scratch in-order to help and support the network or any general project.

Pneumaticat has this to say:- >My homeserver (potatofrom.space) is open for some public registration! Also on Atreatis's matrixservers.net.

They promise 'One nine of uptime guaranteed, or your money back' which sounds pretty like a bargain.

So that's it folks, until next week. Come and say hi at #twim:matrix.org

Well here it is: Synapse 1.0.

Synapse 1.0 is the reference implementation of the Matrix 1.0 spec. The goal of the release overall has been to focus on security and stability, such that we can officially declare Synapse (and Matrix) out of beta and recommended for production use. This means changing the default room protocol version used for new rooms to be v4, which includes the new state resolution algorithm, as well as collision-resistant event IDs, which are now formatted to be URL safe.

Synapse 1.0 also ships with support for the upcoming v5 room protocol (which enforces honouring server key validity periods), but this will not be used as the default for new rooms until a sufficient number of servers support it.

Please note that Synapse 1.0 does not include significant performance work or new features - our focus has been almost exclusively on providing a reference implementation of the Matrix 1.0 protocol. But having cleared our backlog on security/stability issues we will finally be now unblocked to pursue work around reducing RAM footprint, eliminating forward-extremity build up, and shipping new features like Edits, Reactions & E2E cross-signing support.

As part of the security work, Synapse 1.0 contains a breaking change that requires a valid TLS certificate on the federation API endpoint. Servers that do not configure their certificate will no longer be able to federate post 1.0.

It is also worth noting that Synapse 1.0.0 is the last release that will support Python 2.x and Postgres 9.4. For more information see here but the TL;DR is that you should upgrade asap.

This release has been a long time coming. Many thanks indeed to everyone who helped test the release candidates and provided feedback along the way.

Synapse 1.0 is just one component of a larger Matrix 1.0 release, which you can read all about here.

As ever, you can get the new update here or any of the sources mentioned at https://github.com/matrix-org/synapse. Note, Synapse is now available from PyPI, pick it up here. Also, check out our Synapse installation guide page

0.99.5.2 contains a critical performance fix following a regression that was introduced in 0.99.5. Affected servers will have experienced increased CPU and RAM usage with a knock on effect of generally sluggish performance.

Separately, we are also looking into reports relating to further performance degradations that may have been introduced as part of 0.99.5, though consider the 0.99.5.2 fix to be a significant improvement on previous 0.99.5.x releases.

Please upgrade asap.

You can get the new update here or any of the sources mentioned at https://github.com/matrix-org/synapse. Note, Synapse is now available from PyPI, pick it up here. Also, check out our Synapse installation guide page.

Synapse v0.99.5.2 Changelog

Bugfixes

• Fix bug where we leaked extremities when we soft failed events, leading to performance degradation. (#5274, #5278, #5291)

Okay folks, this is an important one. v0.99.5.1 will be the last release before we ship Synapse v1.0. It is really important that you upgrade to v0.99.5.1 because it implements rooms version 4 - which is the room version that Synapse 1.0 will default to.

This means that Synapse 1.0 servers will create new rooms as version 4 by default and servers that have not upgraded to at least v0.99.5.1 will not be able to join those rooms.

Over the coming days we will announce a release day for Synapse v1.0, the idea is to give admins 2 weeks notice so that anyone yet to configure their federation SSL certificate has time to do so. This is important, failure to configure your certs will mean not being able to federate with v1.0 servers. If you are not sure if you certs are valid, you can test here and read here for more info on what to do.

Aside from room v4, this release also includes the ability to blacklist specific IPs from federating as well as experimental support for edits and reactions. We are not quite ready to mark the feature 'done done', but it is very close. Watch out for news as the feature lands properly.

We're really close to v1.0 now, give us a few more days and we'll announce an official release date.

As ever, you can get the new update here or any of the sources mentioned at https://github.com/matrix-org/synapse. Note, Synapse is now available from PyPI, pick it up here. Also, check out our Synapse installation guide page

Hello and welcome

No Ben this week. I'm afraid this means no matrix live, but fear not your Ben orientated programming will resume next week.

Things that have happened

Riot Android

• New Riot.im application has been delivered to the PlayStore: https://play.google.com/store/apps/details?id=im.vector.app. It replaces the previous app. More details here: https://medium.com/@RiotChat/riot-im-android-security-update-2b3f655ad739
• François and Benoit were at AndroidMakers Paris on Tuesday and Wednesday. We’ve seen plenty of interesting conferences and come back with many ideas to improve Riot UX/UI/Implementation/testing/etc.
• SAS device verification review is over, will be merged once we have the tagged OLM library.

RiotX (Android)

• Valere has started working on reactions (which will be implemented only on RiotX for Android).
• François has worked on merging membership Events in the timeline

Riot iOS

• Interactive device verification has been merged
• Jitsi and WebRTC updates have been merged
• Fix bugs in order to prepare a release

Crypto

uhoreg reports that:

olm 3.1.0 has been released. This release adds new functions to help with SAS-based key verification (a.k.a. emoji-based verification) and with cross-signing. The Python bindings are also now available on pypi, so you can install it using "pip install python-olm", though you need the olm library and development files installed first.

Also

• Python-olm available on pypi.
• Initial SAS verification support for nio.

Spectral

Black Hat reports that:

Spectral's redesign continues, featuring a beautiful responsive UI(not kirigami yet, sorry) and more functionalities. Legacy UIs such as the room detail panel are changed to fit into redesigned UI better. Basic room upgrade support is added, allowing you to switch between the old room and the new room. Room settings and user detail dialogs are added. You can also ignore users in the user detail dialog.

matrix-nsfw

A Black Hat double header this week:

matrix-nsfw has been ported from Golang to Rust. The backend machine learning framework is also switched to Tensorflow, giving a major performance boost. For anyone that doesn't know what matrix-nsfw is, it is a bot-like utility that detects NSFW images in a room. The new repo is at https://gitlab.com/b0/matrix-nsfw-rust

Neo

Sometimes a picture tells a thousands rainbow coloured words. Thanks Foks

Ruma

Jimmy reports that:

All of Ruma's libraries (but not yet the homeserver itself) are now targeting stable Rust!

Continiuum

yuforia reports that:

• If a room member is not visible on screen, updating their name doesn't require switching to the main UI thread

• Apply formatting when viewing the json source of an event
• Reuse GUI components to improve performance, update content of views instead of creating new ones
• Use a hash set to avoid going through the list of room members in some cases * Move more of local storage into the database: names and avatars of users and rooms, room membership, recently used accounts, etc.
• Placeholder avatars are made with GUI components and instead of generated bitmap images
• Switch to gradle multi-project build to modularize

After switching from plaintext files to an embedded database, some components are still in the process of being rewritten, coming next week: load messages from server on demand when scrolling, if they are not yet stored in database; add support for invitations;

matrix-appservice-discord

Sorunome reports that:

matrix-appservice-discord work has finally resumed! The PRs for both migrating the room and user store to SQL have been merged, and many awesome new things should follow up soon!

Synapse

The reactions and edits API is taking shape, we’re making progress on our small homeserver setup, and we’re hunting a new set of device key management bugs that came to light in the absence of matrix.org.

We’ve been a bit disrupted these past few weeks, but work towards Synapse 1.0 continues and we’ll soon be ready to offer a release candidate.

miniVector

Curious Cat reports that: >miniVector 0.8.29 is available on Goldy and Froid (and are unaffected by the Riot/Android re-release drama).

The 'Incident'

We know you'll have a bunch of questions, we'll be publishing a full post-mortem next week. Thanks for bearing with us.

The End

See you next week, it will be Bentastic I can assure you. Be sure to stop by #twim:matrix.org with your updates!

TL;DR DON'T PANIC - Synapse 1.0 will support Postgres 9.4 and Python 2.7

Folks, this is an update to explain that we will be shortly deprecating Synapse support for Postgres 9.4 and Python 2.x.

What are we doing?

From the dates described below, we will no longer guarantee support for deprecated versions. This means that Synapse may continue to work with these versions but we will not make any attempt to ensure compatibility and will remove old library versions from our CI.

When is this happening?

Synapse 1.0 will continue to support both technologies, but subsequent releases may not:-

For Python, we shared that we would discontinue to Python 2.x support from April 1st 2019, so for the first release that follows 1.0 we do not guarantee Python 2.x support.

For Postgres, will give server admins 6 weeks to upgrade to a newer version, and will guarantee support up until 20th May 2019.

Why would you do this to us?

We have multiple reasons, but broadly:-

• We want to make use of new language features not supported in old versions. This will enable us to continue to improve the performance and maintainability of Synapse.
• Python 2.x overall will be end of life'd at the end of the year. Postgres 9.4's final release will follow 2 months later on 13th February 2020.
• Since very few server admins still use these technologies on the wild, providing support is costly and we want to reduce our overall maintenance load.

La la la I am ignoring you - what will happen?

You will be able to upgrade to Synapse 1.0, but will likely experience incompatibilities that prevent you upgrading further. Seriously, you really need to upgrade.

Okay, but I have questions, where should I go?

Come and say Hi in #synapse:matrix.org and we'll do our best to help you.

Hey hey, a Synapse release for you today.

The big news in 0.99.3 is that the user directory has been completely re-written and should now be much more performant - this will benefit all installations, but especially those housing larger servers.

Aside from that we continue our 1.0 preparations and relatedly we've improved our docs, in particular to explain how .well-known works. On the perf side we've added rate limiting to login and register endpoints as well as now batching up read receipts to send over federation.

I've said it before, and I'll say it again:-

The most important thing that admins should know is that prior to 1.0 landing later this month, it is essential that the federation API has a valid TLS certificate - self signed certificates will no longer be accepted. For more details see our handy guide. Failure to do this will result in being unable to federate with other 1.0 servers.

As ever, you can get the new update here or any of the sources mentioned at https://github.com/matrix-org/synapse. Note, Synapse is now available from PyPI, pick it up here. Also, check out our new Synapse installation guide page.

TL;DR

• If you run a Synapse ensure that your federation certificates are valid here.
• If they are not valid check out the FAQ.
• Follow along with progress at https://arewereadyyet.com
• Tell all your admin friends.

Folks, as you know we are now very close to achieving Matrix 1.0 and finally being in a position to shed our ‘beta' tag. It has been a long time coming and speaks to the huge effort from hundreds of people over the past 5 years.

A critical step towards this goal is the release of Synapse 1.0. We want to ship Synapse 1.0 as soon as possible but can't do so without your help!

We'd like to introduce AreWeReadyYet.com - a quick and easy way for everyone to track the progress and check if their federation is ready for Matrix 1.0!!

Synapse 1.0 is good news for anyone running a Synapse installation - it contains critical bug fixes, security patches, a new room algorithm version and dramatically improved user and room search. However, as part of the security work it also contains a breaking change from previous Synapse versions. From 1.0 onwards it will necessary to ensure a valid TLS certificate on the federation API. Self signed certificates will no longer be accepted. Why would we do such a thing?

In anticipation for this, everyone currently running a homeserver must ensure that they have checked their federation certificate (check yours here). Failure to do so will mean being unable to federate with any Matrix 1.0 compliant server. If your server fails the check, our FAQ has all the details on what you need to do.

This post is a call to arms to try and get as many admins to upgrade their certificates as possible. We are tracking adoption at https://arewereadyyet.com - currently this sits at about 55% - we need this figure to be higher before we can pull the lever.  

So what are you waiting for? Check that your server has valid certs - then tell all your admin pals to do the same. Friends don't let friends miss out on Synapse 1.0, send them to arewereadyyet.com (or tweet here to remind them!) We really need the community to help us here because at some point soon, we will need to pull the lever and release.

Once we make more progress on adoption, we will announce an official release date and finally get Synapse out of beta!

Well now, what have we here? Synapse 0.99.2 is the latest in the 0.99.x series as we step ever closer to 1.0.

0.99.2 is an incremental release including a bunch of performance improvements, enhancements to room upgrades and generally a plethora of bug fixes.

The most important thing that admins should know is that prior to 1.0 landing later this month, it is essential that the federation API has a valid TLS certificate - self signed certificates will no longer be accepted. For more details see our handy guide. Failure to do this will result in being unable to federate with other 1.0 servers.
