The first public beta of Trillian 2.0 has just been released. Unlike the private beta, Jabber actually works in this one! This round of testing is open to anyone with an active Trillian subscription ($25/yr).
They go on and on about all the fancy new features added since the last version, 1.0C, but the only one that I actually care about and will use is the Jabber plugin. It seems to be working pretty well so far.
If you’re not a paying member, you can download it from trillian.net.ru. Gotta love those Russians.
