      * Before this update, when a new secret was created or updated in any namespace, Alertmanager was reconciling even if that secret was not referenced in the `AlertmanagerConfig` resource. As a consequence, the Prometheus Operator generated excessive API calls, causing increased CPU usage on control plane nodes. With this release, Alertmanager only reconciles secrets that the `AlertmanagerConfig` resource explicitly references. (link: https://issues.redhat.com/browse/OCPBUGS-61965[OCPBUGS-61965])
