* Fixed potential infinite loop that can occur when NFS PVs are recycled. ([#62572](https://github.com/kubernetes/kubernetes/pull/62572), [@joelsmith](https://github.com/joelsmith))
* Fixed column alignment when kubectl get is used with custom columns from OpenAPI schema ([#56629](https://github.com/kubernetes/kubernetes/pull/56629), [@luksa](https://github.com/luksa))

*   Added --dry-run option to kubectl drain. ([#52440](https://github.com/kubernetes/kubernetes/pull/52440),[ @juanvallejo](https://github.com/juanvallejo))

- Now users can get object info like:

  ```bash
    a. kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[0:3].name
    b. kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[-2:].name
  ```

- Dry-run is promoted to Beta and will be enabled by default. ([#69644](https://github.com/kubernetes/kubernetes/pull/69644), [@apelisse](https://github.com/apelisse))
- `kubectl get priorityclass` now prints value column by default. ([#69431](https://github.com/kubernetes/kubernetes/pull/69431), [@Huang-Wei](https://github.com/Huang-Wei))

* Get command uses OpenAPI schema to enhance display for a resource if run with flag 'use-openapi-print-columns'.  ([#46235](https://github.com/kubernetes/kubernetes/pull/46235), [@droot](https://github.com/droot))
    * An example command:

- kubectl: `--use-openapi-print-columns` has been deprecated in favor of `--server-print`, and will be removed in a future version. ([#65601](https://github.com/kubernetes/kubernetes/pull/65601), [@liggitt](https://github.com/liggitt))

- `kubectl get --watch=true` now prints custom resource definitions with custom print columns. ([#76161](https://github.com/kubernetes/kubernetes/pull/76161), [@liggitt](https://github.com/liggitt))

- Kube-apiserver: jsonpath expressions with consecutive recursive descent operators are no longer evaluated for custom resource printer columns ([#93408](https://github.com/kubernetes/kubernetes/pull/93408), [@joelsmith](https://github.com/joelsmith)) [SIG API Machinery]
