- The `--pod` flag (`-p` shorthand) of the kubectl exec command has been marked as deprecated, and will be removed in a future version. This flag is currently optional. ([#66558](https://github.com/kubernetes/kubernetes/pull/66558), [@quasoft](https://github.com/quasoft))

* 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 COS images must be moved to the new directory, and installation processes must be updated with the new path.

* The priorityClass feature is now considered beta. ([#63724](https://github.com/kubernetes/kubernetes/pull/63724), [@ravisantoshgudimetla](https://github.com/ravisantoshgudimetla))
* client-go: credential exec plugins is now considered beta. ([#64482](https://github.com/kubernetes/kubernetes/pull/64482), [@ericchiang](https://github.com/ericchiang))

- Fix an ephemeral port exhaustion bug caused by improper connection management that occurred when a large number of objects were handled by kubectl while exec auth was in use. ([#112336](https://github.com/kubernetes/kubernetes/pull/112336), [@enj](https://github.com/enj)) [SIG API Machinery and Auth]

- Fixed a bug where the kubelet choose the wrong container by its name when running `kubectl exec`. ([#113041](https://github.com/kubernetes/kubernetes/pull/113041), [@saschagrunert](https://github.com/saschagrunert))

- `kubectl run` can set a service account name in the generated pod
  spec with the `--serviceaccount` flag.

- `kubectl proxy` now correctly handles the `exec`, `attach`, and
  `portforward` commands.  You must pass `--disable-filter` to the command to allow these commands.

- Added `cronjobs.batch` to "all", so that `kubectl get all` returns them.

 - Modify a crashing container for easier debugging by changing its image, for example to busybox, or its command, for example, to `sleep 1d` so you have time to `kubectl exec`.
 - Inspect configuration files on a node's host filesystem
