The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source Community has to offer. The Jaunty Jackalope Alpha 3 will be the third alpha release of Ubuntu 9.04, bringing with it the earliest new features for the next version of Ubuntu.
Highlights of this version are: updated packages, X.Org server version 1.6, a new style for notifications and notification preferences, Linux kernel version 2.6.28, and ext4 installation support.
Note that this is an alpha release and should therefore not be installed on production machines. The final stable version is expected on April 23, 2009.
