| * Before this update, if the OVN-Kubernetes controller was not processing updates from the Kubernetes API server and configuring the open virtual network (OVN) databases on each node, then the OVN-Controller, which consumed this database, might have connected to the database before the OVN-Kubernetes controller had configured them. As a consequence, the OVN-Controller synced with a stale OVN database, consumed source network address translations (SNATs) that were configured to support the egress IP, and proceeded to the gratuitous address resolution protocol (GARP) for the associated IP even though that IP might have moved to another node. With this release, these GARPs are blocked when the OVN-Kubernetes controller is not processing updates. (link:https://issues.redhat.com/browse/OCPBUGS-62671[OCPBUGS-62671]) | ||

| * Before this update, the Cluster Version Operator (CVO) in 4.19.9 and 4.18.23 started to require bearer token authentication in metrics requests. As a consequence, HyperShift and Hosted clusters were broken where the metrics scraper currently provides no client authentication. With this release, the CVO does not require client authentication for metrics requests. As a result, access to cluster-version operator metrics is recovered on HyperShift clusters.
