The first betas for version 14.10 of the Kubuntu, Xubuntu, Lubuntu, Ubuntu GNOME and Ubuntu Kylin variants of Ubuntu have been released. Canonical itself will, as usual, only release a Final Beta a few weeks before Ubuntu 14.10 is ready.
Kubuntu 14.10 Beta 1 includes KDE Software Collection 4.14. There’s a special test image for the Plasma 5 desktop as well. The Ubuntu GNOME beta uses GNOME 3.12; Xubuntu and Lubuntu only bring smaller updates.
Meanwhile Ubuntu’s daily builds are available in two versions now. One uses Unity 7 and the “Ubuntu Desktop Next” image uses Unity 8. The next version of Canonical’s desktop is still a bit too experimental for daily use ATM.
Ubuntu 14.10 is scheduled for release on 23 October.
