Ubuntu Unleashed

This release incorporate improvements from Google Summer of Code 2007, Myspace IM, and bug fixes.

This release includes enhancement on the XMPP protocol made by Andreas Monitzer during the Google Summer of Code for Adium, more information can be found on Adium page.

Another feature I really enjoy is the ability to revert to the old gaim layout. For instance, a new entry in the menu Buddy->Show allows you to show protocol icons in the buddy list, right-clicking the empty space in the formatting toolbar allows you to toggle back to the old "ungrouped" version.

Yet, much more is shipped with this release of pidgin. Here is the complete changelog:
