* If the serialization type is 'application/json':
    * If serialization fails, and the original status code was an failure (e.g. 4xx or 5xx), the original status code will be returned.

* Don't remove extended resource capacities that are not registered with kubelet from node status. ([#53353](https://github.com/kubernetes/kubernetes/pull/53353), [@jiayingz](https://github.com/jiayingz))

- Fix CustomResourceDefinition status.storedVersions validation error messages. ([#119653](https://github.com/kubernetes/kubernetes/pull/119653), [@sttts](https://github.com/sttts)) [SIG API Machinery]

- Pod Log stats for windows now reports metrics ([#99221](https://github.com/kubernetes/kubernetes/pull/99221), [@jsturtevant](https://github.com/jsturtevant)) [SIG Node, Storage, Testing and Windows]

  - Added `allocatedResources` field to container status in pod status that describes the node resources allocated to a pod.
  - Added `resources` field to container status that reports actual resources applied to running containers.
  - Added `resize` field to pod status that describes the state of a requested pod resize.

*   Fixed a bug where the `client-gen` tag for code-generator required a newline between a comment block and a statement.  tag shortcomings when newline is omitted ([#53893](https://github.com/kubernetes/kubernetes/pull/53893)) ([#55233](https://github.com/kubernetes/kubernetes/pull/55233),[ @sttts](https://github.com/sttts))

## Before Upgrading

* When Response is a `metav1.Status`, it is no longer copied into the audit.Event status. Only the "status", "reason" and "code" fields are set.  For example, when we run `kubectl get pods abc`, the API Server returns a status object:

* Fix dockershim CreateContainer error handling ([#61965](https://github.com/kubernetes/kubernetes/pull/61965), [@Random-Liu](https://github.com/Random-Liu))
* When updating /status subresource of a custom resource, only the value at the `.status` subpath for the update is considered. ([#63385](https://github.com/kubernetes/kubernetes/pull/63385), [@CaoShuFeng](https://github.com/CaoShuFeng))
