As expected, Ubuntu 11.04 (codenamed "Natty Narwhal") was released on Thursday afternoon. Ubuntu 11.04 Alpha 1 uses the Linux 2.6.37 kernel, a very early snapshot of Canonical's Unity desktop, updated GNOME 3.0 applications, and much more.
Yesterday we posted screenshots of Ubuntu's Unity
as found in this first Natty alpha release. Besides that though there isn't too much to be found in Ubuntu 11.04
over the two-month-old Ubuntu 10.10 release.
The first Ubuntu Natty alpha release was announced by Kate Stewart
, who is one of Canonical's newest employees and will be serving as the Ubuntu release manager going forward.
