I'd like to propose adding a new processing hint to XEP-0334 to support silent/whisper messages - messages that are delivered normally but don't trigger notifications on the recipient's device.
Use Case:
My mother and I communicate via XMPP throughout the day. She frequently participates in screen recordings and video calls (about 1 hour daily) where notification sounds and popups would be disruptive. However, she doesn't want to use DND mode because she needs to remain reachable for genuine emergencies.
The solution we need: the ability to send non-urgent messages silently so she can read them when she next checks her client, without interrupting her work.
User Demand:
This feature is heavily requested across messaging platforms. A quick search shows thousands of users asking "how to send silent messages" or "send without notification" for Facebook Messenger, WhatsApp, Telegram, and other platforms. Telegram already implements this as "send without sound." The demand is clear and widespread.
Proposed Addition to XEP-0334:
A <no-notify/> processing hint with the following semantics:
<message to='recipient(a)example.com' type='chat'>
<body>Please look at the following when you have time: ...</body>
<no-notify xmlns='urn:xmpp:hints'/>
</message>
Behavior:
- The receiving client SHOULD NOT trigger audio/visual notifications
- The message SHOULD still be delivered and stored normally
- The message SHOULD appear in the chat history
- The message MAY still update unread counts (implementation-dependent)
- Clients MAY provide UI indication that a message was sent silently
Benefits:
- Allows nuanced communication without forcing binary DND states
- Respects recipient's focus/workflow while maintaining async communication
- Reduces notification fatigue
- Provides sender control over message urgency
- Simple to implement - clients already have notification suppression logic
Backwards Compatibility:
Clients that don't recognize <no-notify/> will simply deliver the message normally, which is acceptable fallback behavior.
This would be a natural extension to the existing hint types in XEP-0334 (no-store, no-copy, store, no-permanent-store) and addresses a genuine gap in XMPP's messaging capabilities.
Thoughts? Is this something the community would support adding to XEP-0334, or would it be better suited as a separate XEP?
Best regards,
L.G.

Hey all,
Some of you have heard me talk about this at the Summit, but I'd like to
revisit/reexamine our QUIC binding to improve performance of XMPP on low
bandwidth. I'm not sure we'll get to this at the Summit, and there's not
many who want to talk about it so I wondered if this summit topic could
have been an email. (Except then we discussed it anyway)
The primary concerns on low bandwidth - beyond sending fewer bytes on the
wire - are round-trips and head-of-line blocking.
I think XMPP has a good story on round-trips; we're down to very few during
authentication and connection setup, and during normal messaging operation
we don't worry about latency at all.
Head-of-Line blocking, or HoL Blocking, is when - in our case - packet loss
causes the stream to stall until the packet is retransmitted, which is at
least a round-trip away - and can be more due to bandwidth-delay product.
At the same time, we cannot eliminate this entirely (by, say, sending
stanzas over UDP directly) because if we do that we lose the ordering. Out
of order messages can be confusing, and lead to bad misunderstandings.
The rules on this are in RFC 6120, and are rather more complicated than we
normally worry about - normally, we just process everything on a strea, in
order, and this does satisfy the rules. But the rules allow us to process
stanzas in any order we like, as long as
So, what I'm thinking is a way to use the additional channels in QUIC such
that we open multiple channels on both C2S and S2S sessions, which would
form part of the same virtual stream, and we can distribute messages such
that we maintain ordering within messages where we need to, but allows us
to out-of-order (and avoid HOL Blocking) messages sent between unrelated
jids.
This differs to the existing XEP, where each channel maps to a single XML
Stream and XMPP session.
Notes from the Summit:
WEBTRANS would also be of interest, but "raw" QUIC has some advantages as
well, so we probably want both with a uniform approach.
So, my plan is to get an implementation together and a XEP.
Anyone else interested?
Dave.
Hi all,
At the recent Summit, we had a long and nuanced discussion about the state
of the XMPP RFCs and whether there is value in updating parts of them,
potentially through the IETF, to better reflect how XMPP is actually
implemented and used today.
To be clear upfront: This is not a proposal to start an IETF working group,
nor a commitment to produce new RFCs. The discussion at the Summit surfaced
enough open questions that it seems worthwhile to first have a focused
scoping and feasibility discussion.
Some of the motivations that were raised:
- The current RFCs do not describe a baseline that results in
interoperable modern implementations
- Discoverability for new implementers is difficult (knowing which XEPs
are "essential")
- The IM landscape has changed significantly since the original RFCs
- External review and feedback could be valuable
- There may be marketing and positioning benefits, but these are
secondary
At the same time, many concerns were raised:
- The sheer amount of work required, and whether we realistically have
the manpower
- Risk of scope creep (e.g., baking too much into RFCs)
- Loss of flexibility compared to the XEP process
- Fear of starting something we cannot finish
- Unclear interaction with compliance suites and the "living standard"
nature of XMPP
- Potential pushback or distraction from other IETF efforts (e.g., MIMI)
Questions that seem worth discussing at this stage:
- Is it useful to think about updating some RFCs (e.g., core, IM), while
leaving the rest to XEPs?
- What would be clearly in-scope vs out-of-scope?
- Is there enough interest and capacity to justify exploring this
further?
- What would be a sensible first step that does not overcommit us?
If you were at the Summit and felt strongly one way or the other, it would
be great to hear your perspective here. If you weren't, fresh viewpoints
are equally welcome.
The goal of this thread is simply to assess whether this topic is worth
pursuing further, and if so, in what very limited and realistic form.
Kind regards,
Guus

released.
Abstract:
This specification provides a way for the initiator of a Jingle

thus taking advantage of message delivery semantics instead of sending
IQ stanzas to all of the responder's online resources or choosing a
particular online resource.
Changelog:

* Send JMI responses to full JID of initiator instead of bare JID
* Send JMI <finish/> element to full JID of both parties (melvo)

I quite like XEP-0392. I didn't honestly think I would when it first
proposed and published, but it's really handy.
But, XEP-0392 doesn't - anywhere - specify what the "input" should be. I
can see some options:
1) Pick the relevant jid. I'm currently using the bare jid for 1:1
conversations, and the XEP-0045 occupant jid (including nickname) for MUCs.
That seems the most obvious, but means nickname changes also change colour.
2) Pick the display name. I could use the name for 1:1 (the one I display,
from Roster etc) and the nickname from a MUC. That has the advantage that
where those are the same, the colour will be consistent - "Zash" will be
coloured the same on all MUCs, for example.
3) Pick the most stable identifier I can. So occupant_id in MUC,
though still bare Jid for 1:1. This would mean the bright pink occupant
would remain bright pink no matter what nickname change they tried. No
escape!
Any suggestions? Or doesn't it matter?
Dave.
