Finally a new look and feel for Yahoo IM. New features include avatars, sounds, display images, OS X Dock indicator, conferencing, Universal Binary, support for iSight, etc.
This is beta 1, and by the time the final release is out, the ability to chat with anyone using Windows Live (MSN) Messenger will be included.
I prefer to use adium for all of my IM needs in one client (AIM: NickStarr, YahooIM: NickStarr_cc, Gtalk:NickStarr).
