Adium, in my opinion the best instant messenger application for Mac OS X, just got better with the long awaited release of version 1.0. It’s wonderful tabbed window interface has been updated, including improved account management. Adium supports 13 instant different messaging (IM) protocols and is open source, so it is free to download, but donations are welcome.
With over 600 enhancements and bug fixes, Adium 1.0 is the culmination of over a year and a half of development. New features include a shiny new default appearance, an installation setup assistant, improved account management, privacy management, iTunes Now Playing status, optional Dock-like hiding of the contact list, grouping of saved status messages, a redesigned chat transcript viewer with improved searching, and much more. Adium 1.0 includes service-specific improvements such as AIM file transfer and Direct Connect image transfer improvements, Yahoo invisible status, receiving of MSN custom emoticons, and Google Talk buddy icons and typing indication support.
