We are preparing Ubuntu MATE Wily Werewolf (15.10) for distribution on October 22nd, 2015 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 15.10 Alpha 2 release?

Here’s what changed in Ubuntu MATE 15.10 since Alpha 2.

  • Updated to MATE 1.10 (mostly).
    • Caja now has an extension manager so plugins can be enabled/disabled at run-time.
    • A new audio mixer library, libmatemixer, has been introduced.
      • Provides an abstract API allowing access to mixer functionality available in the PulseAudio, ALSA and OSS sound systems.
    • Improved multi-monitor support.
    • Theme support has been expanded including Client Side Decorations (CSD) and pop-overs.
    • Full help and documentation is now available.
    • Static code analysis has resulted in many memory leaks being plugged.
    • Lots of bugs fixes. Really, lots.
    • For more details see the MATE 1.10 Release Notes.
  • Updated Ubuntu MATE Welcome 1.0.3.
    • Renamed to Welcome.

    • Added access to backup, firewall and user manager to Getting Started.
    • Added catgories to the Software page.
    • Added a proprietary software toggle to the Software page.
    • Added new applications to the Software page:
      • App Grid.
      • Chromium as an alternative to Google Chrome.
      • Disks.
      • Hardinfo.
      • SpiderOakONE.

    • Deja Dup now has full content menu control in the Caja file manager.
  • Fixed unlocking a locked screen.

How complete is MATE 1.10?

We’re not quite there yet. Here is the list of MATE packages that have not yet been updated to MATE 1.10.

  • atril
  • mate-panel
  • mate-control-center
  • mate-power-manager
  • engrampa
  • mate-applets
  • mate-icon-theme-faenza
  • mate-sensors-applet
  • mate-user-share

That’s quite a list. As I’ve said before I conduct all MATE packaging work in Debian, as part of the MATE Packaging team for Debian. What with summer vacations, civic duty and DebConf 2015 we didn’t quite get all of MATE 1.10 uploaded in time for Beta 1. The packages above should receive their 1.10 updates in the coming days.

Until all the MATE components are updated to 1.10, things could be a bit bumpy. Ubuntu MATE 15.10 Beta 1 might be the most unstable version of Ubuntu MATE we’ve ever released. But everything should be hunky-dory for the final beta next month.
