+==== Bug fixes
+
+* Before this update, the `config-sync-controller` did not log results due to missing logging statements in the code. As a consequence, users experienced silent failures in the `config-sync-controller`. With this release, the `config-sync-controller` logs results enhancing error diagnosis for users. (link:https://issues.redhat.com/browse/OCPBUGS-56788[OCPBUGS-56788])
+
+* Before this update, calls to retrieve an image manifest and metadata using a tagged image name did not cache the result of the lookup. As a consequence, hosted control plane memory usage quickly grew, which created performance issues. With this release, images in hosted control plane using a named tag or canonical name are cached for 12 hours. As a result, hosted control plane memory usage is optimized. (link:https://issues.redhat.com/browse/OCPBUGS-59933[OCPBUGS-59933])
+
+* Before this update, the `agent-based-installer` set the permissions for the etcd directory `/var/lib/etcd/member` as 0755 when using {sno} deployment instead of 0700, which is correctly set on a multi-node deployment. With this release, the etcd directory `/var/lib/etcd/member` permissions are set to 0700 for {sno} deployments. (link:https://issues.redhat.com/browse/OCPBUGS-61313[OCPBUGS-61313])
+
+* Before this update, the `PrometheusRemoteWriteBehind` alert fired if the remote endpoint never received any data. With this release, the `PrometheusRemoteWriteBehind` alert no longer fires if the remote endpoint has not yet received any data. (link:https://issues.redhat.com/browse/OCPBUGS-61486[OCPBUGS-61486])
+
+* Before this update, it was possible for webhook failures to trigger a `kube-apiserver` crash while generating an audit log entry for a request. As a consequence, API server disruptions were possible. With this release, the audit system has been updated so that the `kube-apiserver` no longer crashes and the API disruptions are resolved. (link:https://issues.redhat.com/browse/OCPBUGS-61488[OCPBUGS-61488])
+
+* Before this update, the *Operand details page* in the web console would show additional status items in a third column, which resulted in the content appearing squashed. With this update, the defect has been corrected, so that only two columns display in the details page. (link:https://issues.redhat.com/browse/OCPBUGS-61781[OCPBUGS-61781])
