Daily builds are coming
In any case, the newly official and freshly renamed Ubuntu Gnome project will not participate in the expected release this week of the first beta version of Ubuntu 13.04, but it does plan to release images for the final beta at the end of the month, according to the announcement.
Meanwhile, daily image builds should be available within a few weeks, the developers said. Ubuntu Gnome 13.04 will also include Gnome 3.6, but Gnome 3.8 will be available from the Gnome3-team Personal Package Archive (PPA) repository.
To get a taste of this latest Ubuntu flavor for yourself, download Ubuntu Gnome Remix 12.10 from the project site. A page on the Ubuntu Wiki details the other "Recognized Flavors" of the free and open source operating system.
