+==== Bug fixes
+
+* Previously, the availability set fault domain count was hardcoded to `2`. This value works in most regions on {azure-first} because the fault domain counts are typically at least `2`, but failed in the `centraluseuap` and `eastusstg` regions. With this release, the availability set fault domain count in a region is set dynamically so that this issue no longer occurs. (link:https://issues.redhat.com/browse/OCPBUGS-53226[*OCPBUGS-53226*])
+
+* Previously, the `trusted-ca-bundle-managed` ConfigMap component was a mandatory component. If you attempted to use a custom Public Key Infrastructure (PKI), the deployment would fail because the OpenShift API server expected the presence of the `trusted-ca-bundle-managed` ConfigMap component. With this release, this component is optional so that you can deploy clusters without the `trusted-ca-bundle-managed` config map component when you use a custom PKI. (link:https://issues.redhat.com/browse/OCPBUGS-52896[*OCPBUGS-52896*])
+
+* Previously, the URL for the *Alert Rules* page on the web console was incorrect. With this release, the URL is fixed and the issue is resolved. (link:https://issues.redhat.com/browse/OCPBUGS-52344[*OCPBUGS-52344*])
+
+* Previously, Operator Lifecycle Manager (OLM) sometimes concurrently resolved the same namespace in a cluster. As a consequence, subscriptions reached a terminal state of `ConstraintsNotSatisfiable` because two concurrent processes interacted with a subscription, which caused a CSV file to become unassociated. With this release, OLM no longer concurrently resolves namespaces, so that OLM correctly processes a subscription without leaving a CSV file in an unassociated state. (link:https://issues.redhat.com/browse/OCPBUGS-48662[*OCPBUGS-48662*])
