GAIM developers yesterday released a new beta release of their 2.0.0 development cycle. There has been some decent changes and improvements in this new beta version, including a new notification tray system (instead of closing the program, it minimises). Font sizes have seen improvements, but nothing major. Try it out for yourself and see what you think.
