Yesterday MATE Desktop 1.16 landed in Debian unstable, I did most of the packaging for that a couple of weeks ago but the Ubuntu MATE crowd funding paid for the packaging to be reviewed, improved, sponsored and uploaded
In the small hours of this morning MATE Desktop 1.16 was synced from Debian unstable to the official Ubuntu Yakkety archive. This means MATE Desktop 1.16 will definitely feature in the final release of Ubuntu MATE 16.10
As an added bonus we've also been able to squeeze MATE Dock Applet 0.75 into both Debian unstable and the Ubuntu Yakkety archive in time for Ubuntu MATE 16.10 final. (Did you see that @robint99? ;-))
And if that wasn't good enough, I'm currently working on a build of MATE Desktop 1.16 for Xenial. Providing everything passes testing without issue I hope to publish that to the
xenial-mate PPA later this week or early next.
It is important to note that the Xenial build of MATE 1.16 is still mostly based on GTK2+
