Important message from my talk!
Exclude Insecure Devices is coming!
After April 2026 (or maybe even sooner), if your Matrix device is unverified, you will not be able to talk to someone who is using Element!
Or any other client complying with MSC4153
@TheDailyBurble, happy to help.
Another cool feature of #XMPP are "gateways" that make it relatively easy to connect with other IMs.
e.g.
#Libervia to #ActivityPub and #email (CC @Goffi )
nlnet.nl/project/Libervia
libervia.org
#Slidge to all sorts of other IM like #Matrix, #Mattermost, #Steam, #Discord, #Whatsapp, FB … (CC @nicoco )
Slidge is a chat gateway library for XMPP built in Python, and a set of gateways for other networks.slidge.im
Not related to the outage, really, this morning I found myself searching for federated IM protocols, ideally end-to-end encrypted. I know we have @matrix but was looking for something more DM-oriented like Signal, but federated.
Looked into XMPP, but E2E encryption relies on add-ons. It seems the closest we have to that is actually #Matrix.

Exhausted, happy and looking forwards for next year's conference.
Time to travel home. Thank you all for attending and making the #MatrixConf2025 possible. It was an honor to organize this conference for you !

We had an amazing after show gathering with the activists from @hackstub after a successful last evening of the #MatrixConf2025. It was an interesting exchange, we learned a lot about your work and it was super pleasant to network with other hackers sharing our vision and values we bear as the ecosystem.
Now time to catch some sleep before rocking the last conference day.
Good night & see you tomorrow !
After fixing some issues, migrating my #matrix media off #matrix-media-repo and onto #synapse was surpisingly straightforward.
I've written a short step-by-step list on what to do and put it here for now:

Beeindruckend finde ich den lebendigen und vielfältigen Austausch in den #Matrix Räumen von @librechurch@kirche.social auf synod.im
Von Fragen und Ideen zu digital souveränen Tools, die auf dem Marktplatz diskutiert werden bis zu Erfahrungen und Herausforderungen immer kleiner werdender christlicher Gemeinden im Raum Glauben teilen.
Anyone using #Tammy as a #Matrix messenger client?
What do you think about it? Why do you use it? How much do you use it? On which device type is it installed? What features do you miss?
I would not underestimate the value of having a go-to home server free of charge for people new to #matrix. In the end, it is the members of the foundation to decide whether they agree with the use of the budget they contribute. Are you also a member?

Regarding the more general accusation on #Matrix being just another VC-backed one-company-product, I'd like to refer to another recent post from the foundation, and only quote from its final paragraph:
> … triggered some defensive reaction with other European players in the market. It is a shame that small European players feel the need to fight one another rather than collaborate via open source software against the bigger non-European and proprietary players.

Matrix, the open protocol for secure decentralised communicationsRobin Riley (matrix.org)
The Matrix Foundation now has some volunteer working groups, and a formal process for creating new ones;
matrix.org/foundation/working-…
For example, there's a WG for documenting moderation issues; reducing spam, easier handling of trolls, griefers and grifters.
If you're keen to get involved in keeping the Matrix protocol network fully decentralised, surveillance-free, and non-corporate, this could be a good way.
#TIL that Mattermost is now offering its own bridge to Matrix, which depends on a Synapse instance running alongside the MM server;
mattermost.com/marketplace/mat…
This is what RocketChat were doing since about 2022. Although their documentation suggests they are working on full Matrix support inside the RC server itself, due sometime this month;
Woah! Only now did we discover a great blog post from @wq who discusses the progression from hosting a #Matrix , a #Snikket and a #SimpleX server, to now running a #chatmail relay runtimeterror.dev/self-hosted-…
It's an excellent read, with lots of good advise, including having a public "hello" profile and another unpublished chat profile for private chatting. #deltachat apps have pervasive multi-profile support (and multi-device support) so it's pretty easy to establish such a two-profile setup.
Everyone is now realizing that WhatsApp is evolving towards its latest form (archive.md/L3W74). If you value secure messaging, you may want to check out @signalapp or @matrix (wich is #federated). EPFL also has its own Matrix instance at matrix.epfl.ch (use @element as a client).

The past few days I've been building a small tool for checking how many members of a given Matrix room support which maximum room version. The idea has been sparked by room version 12 being released, so that one can assess the adoption rate for the new room version and make an educated decision on when to upgrade rooms.
You can check it out here:

I know punching down on Matrix is something people like to do here, but this was a good read about how difficult things are for them: lobste.rs/s/muk05v/reflections…
We released version 0.12.1 of #nheko! This release includes a few security fixes around html escaping into the UI and properly attaching a mark of the web on Windows. I highly recommend you upgrade!
This release also takes the first steps to room version 12 compatibility regarding the upcoming #matrix security release.
You can find the release here: github.com/Nheko-Reborn/nheko/…
Enjoy! :)

Just in time for the security release, the first version of the "Room Upgrades" guide on matrix.org is published!
