This post is more than a year old and may be outdated.

We are underwhelmed to announce, quite possibly, our most uninteresting beta release E-V-E-R! ;-) This beta release is all about the plumbing that transitions Ubuntu MATE to GTK 3.20. It really isn’t very interesting from an end-users perspective.

From this point forward we’ll be focusing on fixing as many issues as we can on the lead up to Beta 2 and the final release of Ubuntu MATE 16.10. The 16.10 development cycle was all about the migration to GTK3+ and creating the new foundations upon which to build our “retrospective future”.

We are preparing Ubuntu MATE 16.10 (Yakkety Yak) for distribution on October 13th, 2016 With this Beta pre-release, you can see what we are trying out in preparation for our next (stable) version.

Ubuntu MATE 16.10 Beta 1 As is now customary, our release artwork was made by Ghost Sixtyseven.

What works?

People tell us that Ubuntu MATE is stable. You may, or may not, agree.

Ubuntu MATE Beta Releases are NOT recommended for:

  • Regular users who are not aware of pre-release issues
  • Anyone who needs a stable system
  • Anyone uncomfortable running a possibly frequently broken system
  • Anyone in a production environment with data or workflows that need to be reliable

Ubuntu MATE Beta Releases are recommended for:

  • Regular users who want to help us test by finding, reporting, and/or fixing bugs
  • Ubuntu MATE, MATE, and GTK+ developers
