* `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))

- Added a new container based image for running e2e tests ([#69368](https://github.com/kubernetes/kubernetes/pull/69368), [@dims](https://github.com/dims))
- The `LC_ALL` and `LC_MESSAGES` env vars can now be used to set desired locale for `kubectl` while keeping `LANG` unchanged. ([#69500](https://github.com/kubernetes/kubernetes/pull/69500), [@m1kola](https://github.com/m1kola))

      * Added exported env vars to kubectl plugins so that plugin developers have access to global flags, namespace, the plugin descriptor and the full path to the caller binary.

  * Enhancement
