* Add `kubectl apply edit-last-applied` subcommand ([#42256](https://github.com/kubernetes/kubernetes/pull/42256), [@shiywang](https://github.com/shiywang))

  * Strategic Merge Patch

    * Reference docs now display the patch type and patch merge key used by `kubectl apply` to merge and identify unique elements in arrays.

* The runtimeHandler field on the RuntimeClass resource now accepts the empty string. ([#69550](https://github.com/kubernetes/kubernetes/pull/69550), [@tallclair](https://github.com/tallclair))
* OpenAPI spec and API reference now reflect dryRun query parameter for POST/PUT/PATCH operations ([#69359](https://github.com/kubernetes/kubernetes/pull/69359), [@roycaihw](https://github.com/roycaihw))
