The first daily ISO images of the upcoming Ubuntu 13.04 (Raring Ringtail) operating system were made available by Canonical on the regular FTP website. Ubuntu 13.04 daily builds are now available for download from Canonical's server.
Welcome to the Raring Ringtail Alpha 2 release, which will in time become the 13.04 release.
This alpha features images for Kubuntu and Ubuntu Cloud.
At the end of the 12.10 development cycle, the Ubuntu flavour decided that it would reduce the number of milestone images going forward and the focus would concentrate on daily quality and fortnightly testing rounds known as cadence testing.
