Ce post est ancien de plus d'un an et pourrait être obsolète.

We are preparing Ubuntu MATE Xenial Xerus (16.04) for distribution on April 21st, 2016 With this Alpha 2 pre-release, you can see what we are trying out in preparation for our next (stable) version.

What works?

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

Ubuntu MATE Alpha 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 Alpha 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

What changed since the Ubuntu MATE 15.10 release?
