*   `kubectl create pdb` no longer sets the min-available field by default. ([#53047](https://github.com/kubernetes/kubernetes/pull/53047),[ @yuexiao-wang](https://github.com/yuexiao-wang))
*   The canonical pronunciation of kubectl is "cube control".

#### Create subcommands
  - `create poddisruptionbudget` ([#36646](https://github.com/kubernetes/kubernetes/pull/36646), [@kargakis](https://github.com/kargakis))
  - `create clusterrole` ([#41538](https://github.com/kubernetes/kubernetes/pull/41538), [@xingzhou](https://github.com/xingzhou))

 - The default Bootstrap Token created with `kubeadm init` v1.8 expires
 and is deleted after 24 hours by default to limit the exposure of the
 valuable credential. You can create a new Bootstrap Token with

    - `kubectl create clusterrolebinding anonymous-discovery --clusterrole=system:discovery --group=system:unauthenticated`
    - `kubectl create clusterrolebinding anonymous-access-review --clusterrole=system:basic-user --group=system:unauthenticated`

- `kubectl run` has removed the previously deprecated generators, along with flags unrelated to creating pods. `kubectl run` now only creates pods. See specific `kubectl create` subcommands to create objects other than pods.
