* Fixed issue with kubectl proxy so it will now proxy an empty path - e.g. http://localhost:8001 ([#39226](https://github.com/kubernetes/kubernetes/pull/39226), [@luksa](https://github.com/luksa))
* Fixed an issue where commas were not accepted in --from-literal flags for the creation of secrets. ([#35191](https://github.com/kubernetes/kubernetes/pull/35191), [@SamiHiltunen](https://github.com/SamiHiltunen))

* `kubectl run --env` no longer supports CSV parsing. To provide multiple env vars, use the `--env` flag multiple times instead of having env vars separated by commas. E.g. `--env ONE=1 --env TWO=2` instead of `--env ONE=1,TWO=2`. ([#47460](https://github.com/kubernetes/kubernetes/pull/47460), [@mengqiy](https://github.com/mengqiy))
