      * Previously, using the `oc adm top pvc` command would not show usage statistics for persistent volume claims (PVCs) for clusters with restricted network configurations, such as clusters with a proxy or clusters in a disconnected environment. With this release, usage statistics can be acquired for clusters in these environments. (link:https://issues.redhat.com/browse/OCPBUGS-54168[OCPBUGS-54168])
