- Revised `OpenAPI v2` fetching for CustomResourceDefinitions. CRDs are now aggregated lazily,
  which improves resource usage during installation of many CRDs. As a result, the first request
  to fetch the OpenAPI may be slower. ([#118808](https://github.com/kubernetes/kubernetes/pull/118808), [@Jefftree](https://github.com/Jefftree))

- Removed deprecated command `kubectl stop`.

- Kubectl can now use http caching for the OpenAPI schema. The cache
  directory can be configured by passing the `--cache-dir` command line flag to kubectl.
  If set to an empty string, caching is disabled.

- Kubectl now performs validation against OpenAPI schema instead of Swagger 1.2. If
  OpenAPI is not available on the server, it falls back to the old Swagger 1.2.

- The OpenAPI spec and documentation now reflect the 202 Accepted response path for delete requests. Note that this change in the openapi spec may affect some clients that depend on the error paths.

* 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 get pods --use-openapi-print-columns
