I just released Smack 3.0.0 Beta 2. It includes quite a few bug fixes and improvements since the last beta.
The biggest change is a multitude of improvements to presence handling in the roster. This is going to require code changes if you’‘re already using Smack, so please go into the migration with eyes wide open. Still, there are some really nice changes that tighten how presence works in the library. I’'d love to hear what people think or about any problems people run into.
