We had an awesome time representing Matrix at the Free and Open Source Software Conference! The new (as of FOSDEM) Matrix Foundation Events WG™️ Booth Kit was a great help in making our booth look much nicer and more engaging than ever, with 2 Linux laptops, a MacBook, one Android and a postmarketOS phone, various stickers, a standup about the Foundation, etc etc. For more detail, keep an eye out for Matrix Live! Here is a teaser:

🔗The Matrix Conference Community Hackathon (website)

We're excited to announce that this year's Community Hackathon at The Matrix Conference is in collaboration with Dr. Carla Griggio and the mInt Research Lab on User-centered Messaging Interoperability at the Department of Computer Science, Aalborg University.

On Friday 23rd October, we'll cross the Øresund Bridge to København and spend the afternoon hacking together on a range of Matrix-related projects. We're very grateful to Carla and Aalborg University for their support of this year's Matrix Conference.

We'll be adding more information about the hackathon and logistics (including the straightforward 🇸🇪 🛤️ 🇩🇰 transport options) on the website very soon. Don't worry: we already confirmed that Club Mate is readily available in supermarkets in Copenhagen! 😉

🔗The Matrix Conference schedule (website)

We're starting to send out the first email acceptances to speakers for the Conference! This should happen over the next few days, so prospective speakers, please check the email associated with your talk submission - we need you to click a link to confirm your acceptance. We have a process to get these sent out, so please stand by! We plan to confirm the initial set of content next week, as speakers are able to accept.

Kegan reports

🔗Local-first Conference

A few weeks ago I was at Local-first Conference in Berlin giving a talk about Local-first Matrix. The video for this is now available. I talk about some of the P2P work we've done recently as well as some Hydra work in the form of the ERA paper. It also bridges the two worlds together, since local-first problems are frequently also Matrix problems, there's a lot we can learn from each other.

🔗Matrix Community Workation Krems 2026

Yan says

In case you haven't spent the last few years asleep under a rock, you've probably come across the Matrix Workations: get-togethers where people who work with, on and for Matrix meet up to work together and side by side (here's what the past ones looked like). The next one is coming up, back at the Schwarzes Rössl in Krems, Austria, from 22 August to 13 September 2026.

It's a workation, not a vacation. You can happily keep doing your day job. There are desks, meeting rooms, workshops and the usual infrastructure. But of course there are also topics and project groups we dig into together, so we've split Krems into three blocks:

• Week 1 · Håck ma's (22–30 Aug) ("let's hack" in Austrian slang). Prepping for the Austrian hacker gathering, connecting to the local scene, and exploring hacks from, with and through Matrix. Bring your own Matrix open source project and run a hackathon or bug hunt while you're there.
• Week 2 · Public Sector (31 Aug–6 Sep). Matrix in the public sector, including a project retreat for FITKO (in the NEO project a new Matrix-based fabric for citizen-to-authority communication is being laid). Plus the medical sector, education and universities, and public stuff in general. It's getting tight, but ask us anyway, we try to make things possible.
• Week 3 · Matrix and beyond (7–13 Sep). Matrix in use cases a bit further from the chat case: Home Assistant and IoT, widgets, or whatever your project happens to be.

Grab a ticket (community prices, early-bird until 31 July) at tickets.matrix-community.events. Coming as a project or a group of four? There's a group discount, just ask us for the voucher. And we're still looking for sponsors: sponsoring keeps the community prices low and makes the whole thing possible, so if you or your org would like to support the Workation, please reach out.

Brought to you by Matrix Community Events. Come say hi in #workation-nation-general:datanauten.de.

🔗Last Call for The Matrix Conference Merch Preorders!

Matrix events such as the Conference are always great opportunities to do something special with merch, with exclusive designs never to return! At least for me that's one of the many parts I love about it, right next to the souvenir value of course! For 2026, we decided that last year's white on black edition conference T-shirt and zipper hoodie were plenty stylish, but we wanted more than a re-run. So we decided to expand up everyone's wardrobe opportunities and are going to have black on white (well, reasonably bright grey) this time around! The embroidering will return for the zipper hoodie because we love the quality, feel, and effect, while the T-shirt will be printed. You also might remember the baseball caps we had at FOSDEM earlier this year. Since Conf is going to be in autumn on the verge of the cold season, we are making embroidered beanies in the classic Matrix white on black to keep your ears warm when you go outside to explore Malmö in the evening. Finally we noticed there are still parts of your bodies without Matrix clothing available for them, so I'm really excited to introduce the Matrix socks in Sweden's national colours.

All of this can be preordered before the end of July since we have to make sure we keep to production deadlines. We will do our best to make some of each available for spontaneous decisions on site, but cannot guarantee availability there.

Reserve yours at https://conference.matrix.org/register/!

PS: You will need to make sure your preorder is picked up during the Conference in Malmö, but you can totally order just your merch today if you're not yet sure which ticket you are going to get!

🔗More Volunteering Slots Available

The Matrix Conference is made possible thanks to our awesome sponsors financing it just as well as our awesome volunteer team staffing the welcome desk, operating video equipment, and generally jumping in whenever an extra hand is needed. We have onboarded a lot of volunteers already and our shift booking system was totally booked out while we worked through all these applications from you amazing people, and some have already asked when more will be available. This is (as of writing) the case! If you were waiting for one to free up again, head to our volunteering system and sign up for two shifts to receive a free ticket to the Conference, the limited edition team-only zipper hoodie in special colours, and of course a lot of experience, satisfaction and fun from helping making The Matrix Conference happen!

If you've already signed up a while ago and have received neither an email nor invite on Matrix from us yet, please reach out to us over at #events-wg:matrix.org.

See you soon, your Events WG.

Hey all,

Matrix 1.19 is here! This release brings 6 more MSCs to the spec since the Matrix 1.18 release just over 3 months ago. Aside from clarifying that server ACLs are case insensitive, adding mutual rooms lookup, and making the room directory order implementation-defined, this release brings a couple of commonly requested features to the protocol: encrypted room history sharing and custom emoji.
