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

  * Strategic Merge Patch

    * Reference docs now display the patch type and patch merge key used by `kubectl apply` to merge and identify unique elements in arrays.

- The server-side apply feature is now beta ([#81956](https://github.com/kubernetes/kubernetes/pull/81956), [@apelisse](https://github.com/apelisse))

- Kubectl apply: warning that kubectl will ignore no-namespaced resource `pv & namespace`...

  - [stable] `kubectl` no longer applies defaults before sending objects to the server in create and update requests, allowing the server to apply the defaults. ([kubernetes/features#55](https://github.com/kubernetes/enhancements/issues/55))

## Known Issues

- Completed pods lose logs across node upgrade ([#32324](https://github.com/kubernetes/kubernetes/issues/32324))

  fun canceledBeforeResponseReadSignalsOnFailure_HTTP_2() {
    enableProtocol(Protocol.HTTP_2)
    canceledBeforeResponseReadSignalsOnFailure()
  }

  /**
   * There's a race condition where the cancel may apply after the stream has already been
   * processed.
   */
  @Test
  fun canceledAfterResponseIsDeliveredBreaksStreamButSignalsOnce() {
    server.enqueue(MockResponse(body = "A"))

- Kubeadm: Added `--yes` flag to the list of allowed flags so that it can be mixed with `kubeadm upgrade apply --config` ([#125566](https://github.com/kubernetes/kubernetes/pull/125566), [@xmudrii](https://github.com/xmudrii)) [SIG Cluster Lifecycle]
