Straightaway from OSNews.com:
"This article will briefly discuss the new features found within Gutsy Gibbon and hopefully give you a better idea of what to expect when the final version of Gutsy Gibbons is released in October. Some of the more notable new features are a Graphical Configuration tool for X, improvements in plug-in handling for Mozilla Firefox, revamped printing system with PDF printing by default, fast user switching, new desktop search (Tracker) application and the new AppArmor security framework."
Pretty cool! Ubuntu is growing and growing and growing.
