+
+Previously, reverting pending changes did not revert global settings that require a full site restart.
+Worse, reverting such a change could stop site services like the web server without starting them again, leaving the site unreachable.
+Both issues are now fixed.
+
+The affected settings are:
+
+* _Start during system boot_
+* _Monitoring core_
+* _Access to Livestatus via TCP_
+* _Start Livestatus proxy_
+* _Event Console_
+* _Enable piggyback-hub_
+* _Send traces from Checkmk_
+* _Receive traces_
+* _Enable OpenTelemetry Collector_
+
+The exact set you see depends on your edition.
+
+Note: While the reverted configuration is being applied, the page does not yet update on its own.
+Reload it to see the current status.
