      system race conditions) #8093

      (m_Seen) #8097

• Update to 2.11.4 Version 2.11.4 fixes a crash during a heartbeat timeout
  with clients not yet signed. It also resolves an issue with endpoints
  not reconnecting after a reload/deploy, which caused a lot of UNKNOWN
  states.

  • Bugfixes
    • Cluster
      • Fix segfault during heartbeat timeout with clients not yet signed
        #7997

• Update to 2.11.2 This release fixes a problem where the newly introduced
  config sync “check-change-then-reload” functionality could cause endless
  reload loops with agents. The most visible parts are failing command
  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

  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
