Earlier today, version 1.8.0 has been released. This release adds tests for exciting new XMPP functionality!
Classic XMPP connection setup takes a lot of round-trips: authenticate, bind a resource, enable carbons, kick off stream management, sync the archive. Each one is its own request. Fine on wifi, annoying on a shaky mobile connection.
XMPP offers various XEPs to fix that. SASL2 (XEP-0388) turns authentication into a single extensible envelope instead of a fixed sequence of steps, and everything else here builds on it. Bind 2 (XEP-0386) folds resource binding and feature enablement into that same envelope, so a client can walk away with a fully set-up session in (almost) one shot. And FAST (XEP-0484) lets a client swap its password for a short-lived, rotating token and reconnect to the server, authenticated, in a single round-trip, no SCRAM handshake required.
Put together, a client can go from opening a socket to fully authenticated and ready to send in essentially one round-trip. That’s also exactly the kind of multi-XEP choreography where servers tend to disagree on the details, so we’re glad to have it covered.
Give the new tests a try, and let us know what you find!
