· MSN protocol module was rewritten. This fixes some problems many people were having with the old code lately, and adds support for things like status messages and offline messages.

August 7th, 2010· Too much to mention here, see the Wiki and doc/CHANGES for more details.
· IRC core completely rewritten. This adds support for multiple configurable control channels (for example one channel per group, one per IM account/protocol, a channel with just your offline contacts), easier groupchat support, more flexibility in how nicknames are generated, and finally you can easily change your nickname whenever you want.
· The ability to use libpurple instead of the built-in code. This adds support for more IM protocols and more features. Possibly less stable and lightweight, so by default the built-in code will still be used.
· Support for file transfers.
