Dear all,
the XMPP Standards Foundation (XSF) is exited to announce the 28th XMPP
Summit taking place in Brussels, Belgium next year - just before FOSDEM
2026. The XSF invites everyone interested in development of the XMPP
protocol to attend, and discuss all things XMPP - both in person and
remotely!
The XMPP Summit
The XMPP Summit is a two-day event for the people who write and
implement XMPP extensions (XEPs) (https://xmpp.org/extensions/). The
event is not a typical conference - aside from small and short lightning
talks, there are no long presentations.
Who participates at the Summit?
The participants, where everyone is welcome, are sitting at a round
table to discuss and active participation is encouraged. Similar to an
unconference at the beginning all participants can suggest topics and
others can indicate via votes whether or not they are interested in that
topic.
Afterwards a rough order of topics is established that will be followed
in moderation with the participants.
How does the Summit work?
If you have ever followed a thread on the standards mailing list
(https://xmpp.org/community/mailing-lists/) or taken part in a
discussion on the public XSF channel (https://xmpp.org/community/chat/)
you should be familiar with this - just in person. The different topics
are broken up by short breaks that are great for networking and getting
to know other XMPP developers. Still, if you cannot participate, we will
also provide an online way of joining the discussion.
Agreeing on a common strategy or even establishing a rough priority for
certain features in our decentral and interoperable technology and
protocol can be hard. In-person events do a lot in getting us on the
same page and as an XMPP developer (e.g. client, server, gateway) we
strongly encourage you to come to the summit. (In short: To get the most
out of the summit you should have a background in reading (and maybe
even writing) XEPs).
If you are simply an enthusiastic user or admin we regularly have booths
at various conferences (FOSDEM, CLT, FrOSCon, …) that are a great
opportunity to meet us, too. Either way, everyone is welcome to participate!
If we’ve caught your attention, we will then hopefully see you at the
XMPP Summit 28. Read on!

Good news everybody!
It will come as no shock that we will have a Summit in Brussels, just
before FOSDEM. As is tradition, this includes the XSF dinner, which is
hosted by the XSF for its members, friends, and sponsors to thank them
for their hard work and support for the foundation and its mission. To
quote Ralph: "it's great fun."
The dinner will take place on Thursday 30 January, at restaurant
L'Auberge Bretonne (Brussselsesteenweg 670 – 3090 OVERIJSE). This is, of
course, also tradition. We would love it if you could make it. Please
let us know by filling in the form at https://forms.gle/S9i3wD6dmePHnovK6.
Timely as we are with organising this, you'll get plenty of time, just
as long as you'll fill in the form by Wednesday 18:00 UTC. That's a full
24 hours, who needs that much time to pick things anyway?
If you're not a member or sponsor, feel free to join us, but we'll ask
you to cover the costs of food, drink and transport yourself.
Hope to see you in Brussels,
Edwin

Hi all,
The XSF infrastructure team is planning to move our mailman installation
from a dedicated machine to a cloud service. When doing so, we also plan
to delete some lists that are no longer in use or that could be replaced
with chatrooms. Do we feel the need to keep this list for Summit-related
coordination, or could we use a chatroom instead?
Peter

PS 1. Summit details can be found at
https://wiki.xmpp.org/web/Conferences/Summit_26.
PS 2. If you want to sponsor the Summit and/or our presence at FOSDEM,
we'd be very grateful. Please contact any board member for details.
Hi,
the wiki says I need to send an email to get access to the Wiki and register, so here I am. I'm not much involved in XMPP, apart from forcing my friends to use it :)
I'm curious about the current state, and why XMPP doesn't seem to support pubkey authentication yet.
If anyone wants to put me into the table (I don't necessarily want a wiki account):
Dorota C (dcz), 1st-until end of FOSDEM, don't remember hotel, not in XSF, don't know dinner
Cheers
*Important reminder*
