* New upstream release:

  - fix the updates menu items randomly working (lp: #842946)
  - "Guest Session should not show if guest session was disabled in 
     the display manager" (lp: #835084)
  - segfault fix (lp: #840660)
  - don't display temporary guest user generated username (lp: #844272)
  - respect "show-real-name-on-panel" to hide the username (lp: #812728)
