+==== Bug fixes
+
+* Previously, if you tried to rerun a resolver-based `PipelineRun` from the {product-title} console, the `Invalid PipelineRun configuration, unable to start Pipeline` UI message was displayed. With this release, you can rerun a resolver-based `PipelineRun` with no problem. (link:https://issues.redhat.com/browse/OCPBUGS-48593[*OCPBUGS-48593*])
+
+* Previously, a bug caused requests to update the `deploymentconfigs/scale` sub resource to fail when a matching admission webhook was configured. With this release, you can update to continue without an error. (link:https://issues.redhat.com/browse/OCPBUGS-47766[*OCPBUGS-47766*])
+
+* Previously, the installation program did not validate the maximum transmission unit (MTU) for custom networks on Red{nbsp}Hat OpenStack platforms, which led to an installation failure when the MTU was too small. For IPv6, the minimum MTU is 1280 and 100 for OVN-Kubernetes. With this release, the installation program validates the MTU of Red{nbsp}Hat OpenStack custom networks. (link:https://issues.redhat.com/browse/OCPBUGS-41815[*OCPBUGS-41815*])
