XMPP Carbons and Mobile Optimization I've been doing a little more research into Prosody modules, which add features to the server. It turns out that for the message carbons feature to send updates to clients that were logged off when the messages were sent, message logs must be stored on the server. I have not enabled that feature -- intentionally -- because I view storing chat logs as a potential privacy problem. So, if you want all messages delivered to all clients, you'll have to keep them all logged in. Another set of features which we did not have on the Prosody server are optimizations designed to save battery and bandwidth on mobile devices. Three new modules are now enabled for that purpose. If you're interested in looking them up, they're mod_csi, mod_throttle_presence, and mod_filter_chatstates. In general, they filter out insignificant data when your client is inactive (like user state changes -- online, busy, away, etc.). If these modules cause headaches for anyone, just let me know and I'll disable them again.
