Ubuntu 9.04 Jaunty Jackalope Alpha is now available
As a first Alpha, this release is not recommended for users in search of a stable desktop environment. And there's really not much benefit to downloading it unless you plan to help test and develop Ubuntu 9.04. For the most part Jaunty Jackalope looks a lot like Ubuntu 8.10. The desktop theme and other graphics haven't been altered at all, and for the most part, the operating system comes with the same set of applications as Intrepid Ibex.
So what's different? The developers have been busy re-merging of changes from Debian, the Linux distribution that Ubuntu is based on. Canonical is also working on porting the operating system to run on machines with ARM processors which could lead to Ubuntu showing up on more Mobile Internet Devices and netbooks next year.
There's currently no LiveCD version of Jaunty Jackalope, so if you do decide to download the Alpha, you'll have to grab the alternate or server installation CDs. The full version of Ubuntu 9.04 is scheduled for release on April 23, 2009.
