At long last, the next major version of Ubuntu is all polished up and ready to strut around in front a public audience. Ubuntu 11.10 "Oneiric Ocelot" brings a bevy of changes to Canonical's popular open source Linux operating system, most notably to the Unity shell. Unless you've been playing with a beta build, Oneiric Ocelot is Ubuntu like you've never seen it before.
The Unity interface was first introduced with Ubuntu 11.04 and has been redesigned in version 11.10. There's a new login screen, 14 new wallpapers, a new Alt-Tab switcher, and various "Lenses" (formerly "Places") that now integrates multiple sources and advanced filtering options such as ratings, range, and categories.
Canonical replaced Evolution with Mozilla's Thunderbird as the default email client. For backup duties, Déjà Dup is now included as the default backup tool. Gnome 3.2 is included, as is version 3.0 of the Linux kernel, which brings a number of performance improvements both to ext4 (the default file system) and the process scheduler, Canonical says.
