- `kubectl debug` gains support for changing container images when copying a pod for debugging, similar to how `kubectl set image` works. See `kubectl help debug` for more information. ([#96058](https://github.com/kubernetes/kubernetes/pull/96058), [@verb](https://github.com/verb)) [SIG CLI]

### Documentation

- `kubectl debug` will now print a warning message when using the `--target` option since many container runtimes do not support this yet. ([#101074](https://github.com/kubernetes/kubernetes/pull/101074), [@verb](https://github.com/verb)) [SIG CLI]

### Bug or Regression

* fix race condition when attach azure disk in vmss ([#71992](https://github.com/kubernetes/kubernetes/pull/71992), [@andyzhangx](https://github.com/andyzhangx))
* Fixed kubelet reporting "resource name may not be empty" when mounting a volume very quickly after unmount. ([#71074](https://github.com/kubernetes/kubernetes/pull/71074), [@jsafrane](https://github.com/jsafrane))

    * `kubectl delete node/<nodeName>`
    * or grant self-deletion permission explicitly:
        * `kubectl create clusterrole self-deleting-nodes --verb=delete --resource=nodes`
        * `kubectl create clusterrolebinding self-deleting-nodes --clusterrole=self-deleting-nodes --group=system:nodes`

- Ephemeral containers graduated to beta and are now available by default. ([#105405](https://github.com/kubernetes/kubernetes/pull/105405), [@verb](https://github.com/verb))

### Feature

- Added KMS `v2alpha1` API. ([#110201](https://github.com/kubernetes/kubernetes/pull/110201), [@aramase](https://github.com/aramase))

- Pod spread constraints have been added in alpha. You can use these constraints to control how Pods are spread across the cluster among failure-domains. ([#77327](https://github.com/kubernetes/kubernetes/pull/77327), [#77760](...

rather than booleans. This change to the alpha API is not backwards compatible; implementations of the CRI such as containerd, will need to update to the new API version. ([#58973](https://github.com/kubernetes/kubernetes/pull/58973), [@verb](https://github.com/verb))

* The default Flexvolume plugin directory for COS images on GCE has changed to `/home/kubernetes/flexvolume`, rather than `/etc/srv/kubernetes/kubelet-plugins/volume/exec`. Existing Flexvolume installations in clusters using...
