### Garbage Collector

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 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)) [SIG Apps and Storage]

- Fixed a panic in the node status update logic when existing node has nil labels. ([#66307](https://github.com/kubernetes/kubernetes/pull/66307), [@guoshimin](https://github.com/guoshimin))
- Fix the bug where image garbage collection is disabled by mistake. ([#66051](https://github.com/kubernetes/kubernetes/pull/66051), [@jiaxuanzhou](https://github.com/jiaxuanzhou))

- 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))

### Node

- Fixed help message for `--container-runtime-endpoint`: only unix socket is support on Linux. ([#74712](https://github.com/kubernetes/kubernetes/pull/74712), [@feiskyer](https://github.com/feiskyer))
- Image garbage collection no longer fails for images with only one tag but more than one repository associated. ([#70647](https://github.com/kubernetes/kubernetes/pull/70647), [@corvus-ch](https://github.com/corvus-ch))

- Removed the following deprecated metrics:
  - node_collector_evictions_number replaced by node_collector_evictions_total

  1. Populate new `RuntimeHandler` field in CRI's `ImageSpec` struct during image pulls from container runtimes.
  2. Pass `runtimeHandler` field in `RemoveImage()` call to container runtime in `kubelet`'s image garbage collection. ([#121456](https://github.com/kubernetes/kubernetes/pull/121456), [@kiashok](https://github.com/kiashok))

### 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
