Ubuntu MATE 16.10 Alpha 2 remains powered by the Linux 4.4 LTS kernel that is used in the stable Ubuntu MATE 16.04.1 LTS (Xenial Xerus). However, there are some very interesting changes implemented in this milestone, such as the Unity-like HUD (Heads-Up Display) that Martin Wimpress teased earlier in the week on Twitter. The HUD can be used for running terminal commands directly from the menubar, but it’s not enabled by default. If you decide to test drive Ubuntu MATE 16.10 Alpha 2, you must enable the new HUD feature from the MATE Tweak tool, which has been updated to version 16.10.4 with improved Indicator support via the Message Menu.
