    '__pub_user'. (bsc#1177867)

  - Ensure virt.update stop_on_reboot is updated with its
    default value.

  - Do not break package building for systemd OSes.

  - Support systemd versions with dot. (bsc#1176294)

  - Fix for grains.test_core unit test.

  - Fix file/directory user and group ownership containing
    UTF-8 characters. (bsc#1176024)

  - Several changes to virtualization :

  - Fix virt update when cpu and memory are changed.

  - Memory Tuning GSoC.

  - Properly fix memory setting regression in virt.update.

    is in the future. (bsc#1176397)
