- Fixed parse devicePath issue on Azure Disk  ([#74499](https://github.com/kubernetes/kubernetes/pull/74499), [@andyzhangx](https://github.com/andyzhangx))

### CLI

- Fixed `--help` flag parsing  ([#74682](https://github.com/kubernetes/kubernetes/pull/74682), [@soltysh](https://github.com/soltysh))

- `kubectl run --env` no longer supports CSV parsing. To provide multiple environment
  variables, use the `--env` flag multiple times instead. Example: `--env ONE=1 --env TWO=2` instead of `--env ONE=1,TWO=2`.

- Removed deprecated command `kubectl stop`.

- Kubectl can now use http caching for the OpenAPI schema. The cache
  directory can be configured by passing the `--cache-dir` command line flag to kubectl.
