The following security vulnerability was addressed :

  - CVE-2018-14345: Fixed the authentication, which did not
    check the password for users with an already existing
    session and allowed any user with access to the system
    bus to unlock any graphical session. (boo#1101450)

The following other bugs were addressed :

  - Fallback to embedded theme, if none is set

  - Corrected section name for Wayland

  - Removed patch, which is no longer needed, because bug in
    libxcb was fixed in the meanwhile (boo#1099908)"
