### Action Required

* Bug fix: webhooks now do not skip cluster-scoped resources ([#58185](https://github.com/kubernetes/kubernetes/pull/58185), [@caesarxuchao](https://github.com/caesarxuchao))

not include those `$ref` fields. ([#58438](https://github.com/kubernetes/kubernetes/pull/58438), [@carlory](https://github.com/carlory))

* Webhooks now do not skip cluster-scoped resources. Before upgrading your Kubernetes clusters, double check whether you have configured webhooks for cluster-scoped objects (e.g., nodes, persistentVolume), as these webhooks will start to take effect. Delete/modify the configs if that's not desirable. ([#58185](https://github.com/kubernetes/kubernetes/pull/58185),...

- Fixed an issue with garbage collection failing to clean up namespaced children of an object also referenced incorrectly by cluster-scoped children ([#98068](https://github.com/kubernetes/kubernetes/pull/98068), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Apps]

## Release Notes From SIGs

### SIG API Machinery

- The OwnerReferencesPermissionEnforcement admission plugin now checks authorization for the correct scope (namespaced or cluster-scoped) of the owner resource type. Previously, it always checked permissions at the same scope as the child resource. ([#70389](https://github.com/kubernetes/kubernetes/pull/70389), [@caesarxuchao](https://github.com/caesarxuchao))

- Kube-apiserver: events created via the `events.k8s.io` API group for cluster-scoped objects are now permitted in the default namespace as well for compatibility with events clients and the `v1` API ([#100125](https://github.com/kubernetes/kubernetes/pull/100125), [@h4ghhh](https://github.com/h4ghhh))

* Admission webhooks rules can now limit scope to only match namespaced, or only cluster-scoped resources with a `scope: "Cluster" | "Namespaced" | "*"` field. ([#74477](https://github.com/kubernetes/kubernetes/pull/74477), [@liggitt](https://github.com/liggitt))
