- Update to 1.8.5
  Core:
  * FIX: Livestatus Backend: Fixed exception handling when fetching
    services which are marked to be in a downtime, but the downtime
    defails can not be fetched
  * FIX: Fixed missing Action/perform/* permission for auth
    databases created with NagVis versions newer than NagVis 1.7b3.
    All auth databases which have been created before, have the
    Action/perform/* permission available. It was not possible to
    permit user not having the */*/* permission to the
    acknowledgement and custom actions via the context menu
  Frontend:
  * Multisite Snapin: Improved performance when a lot of users use
  the snapin. The snapin contents were calculated on each access in
  the past. Now, the snapin contents are cached for 15 seconds.
  This gives a good performance boost when multiple users have use
  the snapin while having access to the same set of maps.
