This person attempted to retract a previous message, but it's unsupported by your client.

I'm guessing that this is too deeply integrated into Thunderbird to make "GPLed OMEMO addon that one can install while the rest of Thunderbird remains MPL" an option? ↺

Wait, it seems OTR is an addon. So maybe OMEMO could work the same after all?

Do any clients implement XEP-0450 Automatic Trust Management now?

I really believe it would help a lot with UX. Verifying keys n * m times is jusy cumbersome.

Actually, "cross signing" is the only thing which I think was done well for Matrix. 🤔 It previously worked pretty much like XMPP with OMEMO, but now users verify their own devices once (not on every device) and contacts only verify the user. Pretty sure this would lead to a lot more people encrypting a lot more, which would be a good thing.

erebion, assuming all projects update their DOAP file properly, you can see the ones which support a specific XEP by clicking on the button to the right of the lines here: https://xmpp.org/extensions/#xep-0450-implementations

XMPP clients that does that are doap !

Meta question: what is the relationship between this group and XSF? Is modern xmpp an incubator of sorts that funnels into XSF?

I find myself here as I close in on my first year of heavy XMPP use (thanks to Snikket for the easy self-hosting onboarding) ✏

One of my regular annoyances is that calls (audio/video) are interrupted as I enter or leave my home (a prime time for me to be on a call). I remember someone mentioning that QUIC is part of the solution (https://xmpp.org/extensions/xep-0467.html) but now I'm wondering whether that's the case or whether it's just a client app (Monocles in my case) issue?

(interrupted by network change from wifi to cellular or vice versa)

curiouser, this project is not an XSF project, however there is obviously significant overlap in contributors. The XSF mainly focuses on standardizing the protocols, and this project was set up to focus on the other stuff (usability, interfaces, etc.)

Keeping calls running across network changes is a client thing, but it's an example of something that could potentially be documented here if it doesn't involve extra protocol stuff and 's not too technical

The XSF mainly focuses on standardizing the protocols, and this project was set up to focus on the other stuff (usability, interfaces, etc.) aha, this group is focused on xmpp ecosystem and ux which may occasionally require an XEP but more often is just discussion and documentation around conventions? ↺

My phone can stay on a call on network changes (conversations) maybe there are specific conditions

I've also successfully switched networks during a call

Obviously some reconnection must happen ✏

But it's automatic and seamless, at least in my experience

menel, MattJ are either of you tunneling all traffic through Wireguard?

No

No

I also much between networks during calls very often, always worked fine dig conference.conversations.im ✏

Ok, thanks for these data points. I'll have to test more on my end. I'm most often on audio calls via jmp #, so maybe that's a key to reproducing...
