We have released the first "official" beta of Asterisk-IM for Openfire 3.3.0.
It is available from http://www.igniterealtime.org/projects/openfire/plugins-beta.jsp
The upgrade problems when using the embedded database have been resolved, so upgrading should work fine now.
Please test it and report any problems you encounter.
We are looking forward to a stable 1.3.0 release within the next weeks resolving any outstanding bugs. After that we will be looking at your feature requests, so stay tuned!
