* Support context completion for kubectl config use-context ([#42336](https://github.com/kubernetes/kubernetes/pull/42336), [@superbrothers](https://github.com/superbrothers))
* print warning when delete current context ([#42538](https://github.com/kubernetes/kubernetes/pull/42538), [@adohe](https://github.com/adohe))

- `kubectl config set-context` can now set attributes of the current context, such as the current namespace, by passing `--current` instead of a specific context name ([#66140](https://github.com/kubernetes/kubernetes/pull/66140), [@liggitt](https://github.com/liggitt))
