other clouds.  Please point your clusters to the new registry going forward. \n\nAdmission/Policy integrations that have an allowlist of registries need to include `registry.k8s.io` alongside `k8s.gcr.io`.\nAir-gapped environments and image garbage-collection configurations will need to update to pre-pull and preserve required images under `registry.k8s.io` as well as `k8s.gcr.io`.

## Changes...

- Fixed SELinux relabeling of CSI volumes after CSI driver failure. ([#103154](https://github.com/kubernetes/kubernetes/pull/103154), [@jsafrane](https://github.com/jsafrane)) [SIG Node and Storage]
- Fixed `garbage collection` of dangling `VolumeAttachments` for `PersistentVolumes` migrated to CSI on startup of `kube-controller-manager`. ([#102176](https://github.com/kubernetes/kubernetes/pull/102176), [@timebertt](https://github.com/timebertt))

- Kubelet: add `kubelet_volume_metric_collection_duration_seconds` metrics for volume disk usage calculation duration ([#107201](https://github.com/kubernetes/kubernetes/pull/107201), [@pacoxu](https://github.com/pacoxu))

### API Change

- Kubernetes 1.23 is now built with go1.19.4. To match behavior of previous Kubernetes 1.23 patch releases:
  - `kube-apiserver` defaults the GOGC setting to 63, to approximate go1.17 garbage collection memory performance in heavily loaded API servers

- Fix public IP not shown issues after assigning public IP to Azure VMs ([#90886](https://github.com/kubernetes/kubernetes/pull/90886), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]
- Fixed a regression preventing garbage collection of RBAC role and binding objects ([#90534](https://github.com/kubernetes/kubernetes/pull/90534), [@apelisse](https://github.com/apelisse)) [SIG Auth]

  - [beta] Server-side garbage collection is enabled by default. See [user-guide](http://kubernetes.io/docs/user-guide/garbage-collection/)

### Garbage Collector
* Added foreground garbage collection: the owner object will not be deleted until all its dependents are deleted by the garbage collector. Please checkout the [user doc](https://kubernetes.io/docs/concepts/abstractions/controllers/garbage-collection/) for details. ([#38676](https://github.com/kubernetes/kubernetes/pull/38676), [@caesarxuchao](https://github.com/caesarxuchao))

* custom resources that use unconventional pluralization now work properly with kubectl and garbage collection ([#50012](https://github.com/kubernetes/kubernetes/pull/50012), [@deads2k](https://github.com/deads2k))
