We are preparing Ubuntu MATE Xenial Xerus (16.04) for distribution on April 21st, 2016 With this Beta 1 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 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

What changed since the Ubuntu MATE 16.04 Alpha 2 release?

First of all, I’d like to extend my thanks to:

  • Luke Horwell for introducing dynamic generation of the Software Boutique in Ubuntu MATE Welcome and generally improving the design and function of Ubuntu MATE Welcome.
  • Robin Thompson for adding a translation framework to Ubuntu MATE Welcome. We are finalsing the translation tooling and will be asking for translators to help us from next week.
  • Mike Gabriel for packaging mate-dock-applet, topmenu-gtk and re-instating gir1.2-wnck-1.0 (required by mate-dock-applet) into the libwnck packages for Debian.
  • Iain Lane for mentoring Martin Wimpress so the libwnck package updates in Debian could be synced to Ubuntu.
  • Timo Jyrinki and Daniel Holbach for sponsoring critical package updates for Ubuntu MATE.
  • Ghost Sixtyseven for creating a fantastic new Ubuntu MATE desktop wallpaper called “A Dawn Gift”.
