- Introduced the `scheduling.k8s.io/v1alpha1` Workload API to express workload-level scheduling requirements and allow the kube-scheduler to act on them. ([#134564](https://github.com/kubernetes/kubernetes/pull/134564), [@macsko](https://github.com/macsko)) [SIG API Machinery, Apps, CLI, Etcd, Scheduling and Testing]

  The flowcontrol.apiserver.k8s.io/v1beta3 APIs are deprecated and will no longer be served in v1.32. All existing objects are available via the `v1` APIs. Transition clients and manifests to use the `v1` APIs before upgrading to v1.32. ([#121089](https://github.com/kubernetes/kubernetes/pull/121089), [@tkashem](https://github.com/tkashem)) [SIG API Machinery and Testing]
- The kube-proxy command-line documentation was updated to clarify that

  /** Returns an unmodifiable iterator across the elements in this collection. */
  @Override
  public abstract UnmodifiableIterator<E> iterator();

  @Override
  @IgnoreJRERequirement // used only from APIs with Java 8 types in them
  // (not used within guava-android as of this writing, but we include it in the jar as a test)
  public Spliterator<E> spliterator() {

   * that {@link NullPointerTester} may misbehave under Android when used on classes that rely on
   * type-use annotations.
   *
   * <p>Under j2objc, the necessary APIs exist, but some (perhaps all) return stub values, like
   * empty arrays. Presumably {@link NullPointerTester} could likewise misbehave under j2objc, but I
   * don't know that anyone uses it there, anyway.

## Changelog since v1.21.0

## What's New (Major Themes)

### Removal of several beta Kubernetes APIs

	// Generate string error response.
	writeResponse(w, err.HTTPStatusCode, []byte(err.Description), mimeNone)
}

// writeErrorResponseJSON - writes error response in JSON format;
// useful for admin APIs.
func writeErrorResponseJSON(ctx context.Context, w http.ResponseWriter, err APIError, reqURL *url.URL) {
	// Generate error response.

   * For example, suppose the cookie's domain is `example.com`. If this flag is true it matches
   * **only** `example.com`. If this flag is false it matches `example.com` and all subdomains
   * including `api.example.com`, `www.example.com`, and `beta.api.example.com`.
   *
   * This is true unless 'domain' is present.
