Good morning
the 29th XMPP Summit is fast approaching. It is our first attempt at
an online only Summit and will be held on Friday 4 September and
Saturday 5 September 2026.
If you intent to attend please add yourself to the participants list¹.
Adding yourself might also motivate others to participate itself.
Please find the time to do so even if there is no "limited seating" or
other constraints.
We are also looking for topic suggestions. We will maintain the
unconference style of offline summits (meaning participants can bring
their own topics) but for time constraints we will do the topic
suggestions and topic sorting ahead of time.
Meaning what usually happens on the white board in the first hour of a
traditional summit will now happen on list.
Please go ahead and propose topics and include a short pitch.
Additionally please add the topic to the wiki.² (If you someone only
suggests it here I’ll try my best to add it to the wiki myself.)
I will close the topic suggestion round on Thursday 27th so we will
have about a week to vote on the topics. (which will determine the
order of the four topics we'll be discussing during the Summit)
cheers
Daniel

Dear all,
I’m a little bit involved with the DC EDIC (Digital Commons European Digital
Infrastructure Consortium) and it seems like it could be interesting for the
wider XMPP community.
From its mission:
> DC-EDIC develops, maintains, and scales digital commons for Europe, pooling
> resources across member states to reduce technological dependency.
<https://digital-commons-edic.eu/>
The about page summarizes it pretty well and in short too, so I won’t copy-
paste it here.
They are setting up an EU STF similar to (and together with) the German
Sovereign Tech Fund/Agency to sponsor development and maintenance of important
software.
While the first project is planned to be about a “collaborative workspace
flagship”, communication and messaging is already explicitly part of that.
In my opinion, DC EDIC could prove to be a big vector for getting FOSS,
interoperability and (open-)standard-based formats and protocols into
(European) public administrations and also to get funding for it.
There are things both in the mission and the future project criteria that I
feel resonate with the XMPP ecosystem very well and IMHO it would be a damn
waste not to keep an eye on it and reach out.
For example, there is currently a _call for experts_ out, where not just
countries in DC EDIC, but also FOSS communities may suggest topic experts. I
suggest the XSF puts forward someone there:

Hello everyone,
I keep reading about recent developments in the quantum computing field,
with whatever this may mean for classic asymmetric encryption/key
exchange algorithms. More specifically, it appears that both Google
(Quantum frontiers may be closer than they appear
<https://blog.google/innovation-and-ai/technology/safety-security/cryptograp…>)
and Cloudflare (Cloudflare targets 2029 for full post-quantum security
<https://blog.cloudflare.com/post-quantum-roadmap/>) have targeted 2029
for post-quantum migration. Both of these blog posts made me ponder
about the post-quantum security of the OMEMO. I am not an expert on the
field of asymmetric cryptography, but per XEP-0384
<https://xmpp.org/extensions/xep-0384.html>, OMEMO uses the X3DH key
agreement protocol for key exchange and the Double Ratchet Algorithm for
message encryption and decryption. From what I can grasp, Signal has
developed the PQXDH key agreement protocol as a post-quantum secure
variant of X3DH, while Double Rachet also seems to provide no
post-quantum protection
<https://signal.org/docs/specifications/doubleratchet/#harvest-now-decrypt-l…>.
With that being said, I'd like to ask if there are any plans to update
the relevant OMEMO standard in the future to make OMEMO
post-quantum-proof and if not, whether OMEMO's post-quantum security is
considered trivial or not.
Thanks in advance
Hello everybody,
I would like to bring a discussion on AI policy. We can't really ignore
anymore that modern models have become very capable, and I suspect that they
are used for spec authoring.
This raises, I believe, copyright issues: if someone use AI to redact a whole
section of a spec, how can we be sure that it's not an existing specs for some
other place, possibly under copyright, that is copied or paraphrased? How can
an author guarantee that it's original work (hint: they can't)?
I think that there are 3 distinct uses:
1. As a light formatting/checking help, for instance to generate a table from
a human written section, to correct the formulation of a sentence, or to draft
an example. This is notably useful for non native English speakers.
2. As a help to search existing state of art on some feature, or any kind of
data, without writing anything in a protoXEP.
3. As a way to generate whole sections.
Instinctively, and If we put aside ethical and ecological concerns about LLMs,
I think that 1. and 2. are OK, and 3. should be forbidden. And in all cases,
it should be disclosed.
I would like your feedback on this matter, in particular people with legal
knowledge.
I would like to avoid a flamewar, I know that this topic is sensitive and there
opinions are highly divided, please express your opinion calmly. The fact is,
we can't ignore this anymore.
Should this be discussed with board or council?
Thanks.
Best,
Goffi
Hello,
The Council talked about moving a couple of stable XEPs which have not been modified for years to "Final".
As this process has not been done for a long time, we want to first try with XEP-0066 (Out of Band Data).
Peter, would you be fine with moving this specification to "Final"?
Please not that dwd suggested to get rid of section 6 first (XEP-0095 being deprecated).
If Peter is fine with getting rid of the section and moving forward, we can emit a last call.
Thanks.
Goffi
This message constitutes notice of a Last Call for comments on
XEP-0424.
Title: Message Retraction
Abstract:
This specification defines a method for indicating that a message
should be retracted.
URL: https://xmpp.org/extensions/xep-0424.html
This Last Call begins today and shall end at the close of business on
2025-01-06.
Please consider the following questions during this Last Call and send
your feedback to the standards(a)xmpp.org discussion list:
1. Is this specification needed to fill gaps in the XMPP protocol
stack or to clarify an existing protocol?
2. Does the specification solve the problem stated in the introduction
and requirements?
3. Do you plan to implement this specification in your code? If not,
why not?
4. Do you have any security concerns related to this specification?
5. Is the specification accurate and clearly written?
Your feedback is appreciated!
Version 0.1.0 of XEP-0516 (XMPP Decentralized ID (XID)) has been
released.
Abstract:
XMPP Decentralized ID (XID) is a DNS independent XMPP entity
identifier. This specification describes how to generate, use, and
handle them.
Changelog:
Accepted as Experimental by council vote (XEP Editor (dg))

Hello,
I have updated the Jingle User Location ProtoXEP with clearer wording
after the Council discussion.
The updated draft is here:
https://github.com/xsf/xeps/pull/1550
The main clarification is that this proposal does not replace XEP-0080.
XEP-0080 remains the location payload. The problem this proposal tries
to solve is the call/session binding:
XEP-0080 tells where the user is, but it does not reliably tell for
which active Jingle call that location was shared.
PEP/PubSub is useful for general user-location publication, but for an
active call it does not clearly answer:
- which Jingle session / sid the location belongs to;
- whether the location was explicitly shared for this call;
- whether it is fresh, stale, one-time, or live;
- when call-scoped location sharing stops;
- whether a relay, accessibility assistant or future emergency gateway
may treat it as the location for the active call.
The revised direction is therefore narrower:
A small Jingle binding for XEP-0080 during an active call.
It reuses the existing XEP-0080 geoloc payload and adds Jingle session
context, stop-sharing/expiry wording, fallback wording and privacy
wording. It also explicitly avoids claiming to be an emergency-service
protocol by itself.
The reason I think this matters is accessibility and 112/911-readiness.
A deaf or speech-impaired user may be in a Total Conversation call with
audio, video, RTT, captions, relay/interpreter services or a future
emergency gateway. In that situation the peer or gateway should not have
to guess whether the latest XEP-0080/PEP item belongs to the current call.
Feedback is welcome, especially on whether this narrower “Jingle binding
for XEP-0080” direction is the right shape.
Kind regards,
Edward
