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

- 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-boo
st-166
- command_endpoint objects require a zone:
https://icinga.com/docs/icinga2/latest/doc/16-upgrading-icinga-2/#agent-hos
ts-with-command-endpoint-require-a-zone
- Zones declared in zones.d are not loaded anymore:

events
