From Ubuntu.com:
The Ubuntu developers are moving very quickly to bring you the absolute latest and greatest software the Open Source Community has to offer. The Gutsy Gibbon Tribe 1 is the first alpha release of Ubuntu 7.10, and with this new alpha release comes a whole host of excellent new features. The feature list for 7.10 has been slowly growing more exact since Gutsy opened late last month. While looking forward nothing is completely certain, here are some of the new things that have already arrived, such as GNOME 2.19, a new 2.6.22-rc kernel, as well as a good look at the approved specifications for Gutsy.
