Hi, Didnt know about that PEP sentence, i dont know any implementation that does this, but still if its possible we should limit 0384 to singleton Node usage, but to be honest so should every other XEP that depends on PEP.
you misunderstood me with the max_items=1, yes you can configure a node with max_items=1 but you can also specify this in a pubsub request of a Node (not config): https://xmpp.org/extensions/xep-0060.html#subscriber-retrieve-requestrecent But this seems to be optional *also* So indeed the only not optional thing here is Singleton Node I think this is a good addition to the XEP, although i fear this would be a namespace bump, but from practical experience every PEP impl sends only the last item, so this is until now a academic problem Regards Philipp 2018-07-27 16:26 GMT+02:00 Goffi <go...@goffi.org>: > Hey, thanks for the quick feedback > > Le vendredi 27 juillet 2018, 16:10:38 CEST Philipp Hörist a écrit : > > On the Pubsub Questions: > > > > 1.
