Adam Conrad, on the behalf of the Ubuntu Release Team, tonight announced the final beta of the Ubuntu 15.04 "Vivid Vervet" release.

For those sticking to beta milestones rather than the latest daily snapshots, jump for the final beta of Ubuntu 15.04/Vivid. The final beta is spun for Ubuntu, Ubuntu Server, Ubuntu Cloud, Ubuntu Core, Lubuntu, Kubuntu, Ubuntu GNOME, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, Xubuntu, and other flavors.

Ubuntu 15.04 Beta Final is obviously worth testing out but there's already known bugs as mentioned by the release announcement, so you've been forewarned. I've been testing out Ubuntu 15.04 development snapshots to great success on many different systems but be cautioned for deploying it on any production systems ahead of next month's official Ubuntu 15.04 debut. Ubuntu 15.04 is turning out fairly well though most desktop users won't notice any dramatic differences from the currently stable Ubuntu 14.10 release.
