- `kubectl convert`, deprecated since v1.14, will be removed in v1.17.
  - The `--export` flag for the `kubectl get` command, deprecated since v1.14, will be removed in v1.18.
  - `kubectl cp` no longer supports copying symbolic links from containers; to support this use case, see `kubectl exec --help` for examples using `tar` directly ([#82143](https://github.com/kubernetes/kubernetes/pull/82143), [@soltysh](https://github.com/soltysh))

- `kubectl debug` gains support for changing container images when copying a pod for debugging, similar to how `kubectl set image` works. See `kubectl help debug` for more information. ([#96058](https://github.com/kubernetes/kubernetes/pull/96058), [@verb](https://github.com/verb)) [SIG CLI]

- Report cp errors consistently, providing full message whether copying to or from a pod.  ([#77010](https://github.com/kubernetes/kubernetes/pull/77010), [@soltysh](https://github.com/soltysh))
- Preserved existing namespace information in manifests when running `

* Add RBAC support to fluentd-elasticsearch cluster addon ([#46203](https://github.com/kubernetes/kubernetes/pull/46203), [@simt2](https://github.com/simt2))
* Avoid redundant copying of tars during kube-up for gce if the same file already exists ([#46792](https://github.com/kubernetes/kubernetes/pull/46792), [@ianchakeres](https://github.com/ianchakeres))

* Add limitrange/resourcequota/downward_api  e2e tests for local ephemeral storage ([#52523](https://github.com/kubernetes/kubernetes/pull/52523), [@NickrenREN](https://github.com/NickrenREN))
* Support copying "options" in resolv.conf into pod sandbox when dnsPolicy is Default ([#54773](https://github.com/kubernetes/kubernetes/pull/54773), [@phsiao](https://github.com/phsiao))

The built-in functions <code>append</code> and <code>copy</code> assist in
common slice operations.
For both functions, the result is independent of whether the memory referenced
