- kubeadm: if an unknown command name is passed to any parent command such as 'kubeadm init phase' return an error. If 'kubeadm init phase' or another command that has subcommands is called without subcommand name, print the available commands and also return an error.

  * New commands

    * Add `kubectl config rename-context` ([#46114](https://github.com/kubernetes/kubernetes/pull/46114), [@arthur0](https://github.com/arthur0))

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

*   Added --raw to kubectl create to POST using the normal transport. ([#54245](https://github.com/kubernetes/kubernetes/pull/54245),[ @deads2k](https://github.com/deads2k))
*   Added kubectl `create priorityclass` subcommand ([#54858](https://github.com/kubernetes/kubernetes/pull/54858),[ @wackxu](https://github.com/wackxu))
