- Fixed a regression in default configurations, which enabled PodDisruptionConditions by default, 

- Fixes a bug where images pinned by the container runtime can be garbage collected by kubelet. ([#120056](https://github.com/kubernetes/kubernetes/pull/120056), [@ruiwen-zhao](https://github.com/ruiwen-zhao)) [SIG Node]

## Changes by Kind

### 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

- 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))

    backward compatibility.
*   Move `layers_dense_variational_impl.py` to `layers_dense_variational.py`.

## Known Bugs

*   Using XLA:GPU with CUDA 9 and CUDA 9.1 results in garbage results and/or
    `CUDA_ILLEGAL_ADDRESS` failures.

    Google discovered in mid-December 2017 that the PTX-to-SASS compiler in CUDA
    9 and CUDA 9.1 sometimes does not properly compute the carry bit when

- The garbage collection controller no longer raced with changes to `ownerReferences` when deleting orphaned objects. ([#132632](https://github.com/kubernetes/kubernetes/pull/132632), [@sdowell](https://github.com/sdowell)) [SIG API Machinery and Apps]

node users can delete their corresponding node object by patching themselves with an OwnerReference to a cluster-scoped resource. If the OwnerReference resource does not exist or is subsequently deleted, the given node object will be deleted via garbage collection. By default, node users are authorized for create and patch requests but not delete requests against their node object. Since the NodeRestriction admission controller does not prevent patching OwnerReferences, a compromised node could leverage...

- 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))

- Kubernetes 1.24 bumped version of golang it is compiled with to go1.18, which introduced significant changes to its garbage collection algorithm. As a result, we observed an increase in memory usage for kube-apiserver in larger an heavily loaded clusters up to ~25% (with the benefit of API call latencies drop by up to 10x on 99th percentiles). If the memory increase is...

- 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]
