net.server_select: Deprecate and warn about it To be removed in the future, but not right now. Give the log warning a chance to prod anyone who might have network_backend="select" in their config first. There's also things built on Verse which uses server_select.lua, which will need to be updated somehow.

net.server: Pikc server_epoll as unconditional default Previously it would have gone for server_select if util.poll was for some reason not available, which should be never these days. And even if it was, best to flush it out by throwing loud errors so users notice. Then they can work around it by using select until we delete that one.

net.server: Fall back to default backend from libevent instead of always select Fixes that selecting libevent when unavaibalbe would fall back to select instead of epoll, even if that's available. This way, we only have to update it in once place when choosing a new default.

net.server_epoll: Prevent removed timers from being readded In a case like this the timer would not be readded: addtimer(1, function(t, id) stop(id) return 1 end);

mod_mam: Suppress offline message broadcast for MAM clients MattJ on 09:34:24 > Zash: I think as a first step, offline messages should not be sent to > clients that request MAM https://chat.modernxmpp.org/log/modernxmpp/2021-08-31#2021-08-31-8518a542bd283686

mod_mam: Only check for locally generated stanza-ids Otherwise a message archived by a remote server would be incorrectly silently discarded. This should be safe from spoofing thanks to strip_stanza_id earlier in the event chain.

mod_mam: Explain behavior with absent mod_offline in a comment

mod_mam: "Handle" messages that have been archived in the absense of mod_offline

mod_external_services: Factor out public function for converting to XML Along with the previous commit, allows building the XML thing yourself, should you wish to send it yourself or use it in a different context than an iq reply. API change: The 'reply' is removed from the event.

mod_external_services: Factor out public function returning current services This way you get the _prepared_ services and don't have to do that mapping yourself.
