Because Ubuntu MATE 14.10 was the first Ubuntu MATE release and it's supported for only 9 months, the Ubuntu MATE team released Ubuntu MATE 14.04 LTS yesterday, which is supported until 2019.

Ubuntu MATE is an unofficial (for now) Ubuntu flavor which uses MATE as the default desktop environment. MATE is a GNOME 2 fork introduced after GNOME 3 and GNOME Shell replaced the classic desktop metaphor, which led to some criticism from the Linux community. Currently, MATE only supports GTK2, but the plan is to add GTK3 support with MATE 1.12.





Ubuntu MATE 14.04 ships with MATE 1.8 by default, and not MATE 1.6, which is available in the official Ubuntu 14.04 , and not MATE 1.6, which is available in the official Ubuntu 14.04 repositories . This was possible because Ubuntu MATE is not yet an official Ubuntu flavor and that allowed using the Ubuntu MATE PPAs by default.





Ubuntu MATE 14.04 supports Ubuntu AppIndicators out of the box: Compared to Ubuntu MATE 14.10 , Ubuntu MATE 14.04 LTS comes with quite a few changes, although many of these changes have already been released as updates for Ubuntu MATE 14.10. For instance,

Note that the AppMenu / global menu applet is available but it didn't work in my test.





Also, Ubuntu MATE 14.04 ships with some new packages installed by default:

MATE Tweak (a MintDesktop fork) - a tool which lets you configure which icons to show on the desktop, enable/disable compositing, change the window buttons layout, show/hide icons in menus and buttons and more;
