    functionality could cause endless reload loops with

    endpoint checks with 'not connected' UNKNOWN state. Only
    applies to HA enabled zones with 2 masters and/or 2
    satellites.

  - Bugfixes

  - Cluster Config Sync

  - Config sync checksum change detection may not work
    within high load HA clusters #7565

  - Update to 2.11.1 This release fixes a hidden long
    lasting bug unveiled with 2.11 and distributed setups.
    If you are affected by agents/satellites not accepting
    configuration anymore, or not reloading, please upgrade.

  - Bugfixes

  - Cluster Config Sync

  - Never accept authoritative config markers from other
    instances #7552

  - This affects setups where agent/satellites are newer
    than the config master, e.g. satellite/agent=2.11.0,
    master=2.10.

  - Configuration

  - Error message for command_endpoint should hint that zone
    is not set #7514

  - Global variable 'ActiveStageOverride' has been set
    implicitly via 'ActiveStageOverride ... #7521

  - Documentation

  - Docs: Add upgrading/troubleshooting details for repos,
    config sync, agents #7526

  - Explain repository requirements for 2.11:
    https://icinga.com/docs/icinga2/latest/doc/16-upgrading-
    icinga-2/#added-boost-166

  - command_endpoint objects require a zone:
    https://icinga.com/docs/icinga2/latest/doc/16-upgrading-
    icinga-2/#agent-hosts-with-command-endpoint-require-a-zo
    ne

  - Zones declared in zones.d are not loaded anymore:
    https://icinga.com/docs/icinga2/latest/doc/16-upgrading-
    icinga-2/#config-sync-zones-in-zones
