### Feature

- A `system-cluster-critical` pod should not get a low OOM Score.

   * When handshake is null for an HTTPS URL, the TLS block is skipped making the entry

In addition, the NodeRestriction admission plugin now prevents kubelets from modifying taints on their Node API objects, making it easier to keep track of which nodes should be in use.

### SIG CLI

- Fixed a race condition in kube-controller-manager and the scheduler, caused by
  a bug in the transforming informer during the Resync operation, 
  by making the transforming function idempotent. ([#124352](https://github.com/kubernetes/kubernetes/pull/124352), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery and Scheduling]

* Skip multi-zone e2e tests unless provider is GCE, GKE or AWS ([#27871](https://github.com/kubernetes/kubernetes/pull/27871), [@lukaszo](https://github.com/lukaszo))
* Making DHCP_OPTION_SET_ID creation optional ([#27278](https://github.com/kubernetes/kubernetes/pull/27278), [@activars](https://github.com/activars))

- Filter published OpenAPI schema by making nullable, required fields non-required in order to avoid kubectl to wrongly reject null values. ([#85722](https://github.com/kubernetes/kubernetes/pull/85722), [@sttts](https://github.com/sttts))

	response, err = s.client.Do(request)
	c.Assert(err, nil)
	// assert the status code of the response.
	c.Assert(response.StatusCode, http.StatusOK)

	// constructing http request to delete the bucket.
	// making an attempt to delete an non-empty bucket.
	// expected to fail.
	request, err = newTestSignedRequest(http.MethodDelete, getDeleteBucketURL(s.endPoint, bucketName),
		0, nil, s.accessKey, s.secretKey, s.signer)

- Port mapping now allows the same `containerPort` of different containers to different `hostPort` without naming the mapping explicitly. ([#94494](https://github.com/kubernetes/kubernetes/pull/94494), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev))

  startup/readiness/liveness probe capabilities. Lifecycle handlers configured
  with `scheme: HTTPS` that encounter errors indicating the endpoint is actually
  using HTTP fall back to making the request over HTTP for compatibility with
  previous releases. When this happens, a `LifecycleHTTPFallback` event is recorded
