Ubuntu just released a new Alpha build for Ubuntu 9.04 (Jaunty Jackalope). This alpha includes some small changes like the latest package of X.Org, Linux Kernel 2.6.28, new style for notifications and perhaps most interesting feature for me was the option of installing ext4 file system while default choice is still ext3. As some of you might know ext4 is a vastly improved fork of ext3 file system, which was under development since 2006. ext4 is included with the latest Linux kernel, so it was an obvious choice of transition for Jaunty. Home users who don’t rely on large storage are not likely to experience the real power of ext4 – but it is an exciting option nonetheless.

As with any alpha releases, it is advised to use it with caution under test environment (virtual box install). You can download the latest alpha builds here.
