- UpdateContainerResources is no longer recorded as a `container_status` operation. It now uses the label `update_container`. ([#75278](https://github.com/kubernetes/kubernetes/pull/75278), [@Nessex](https://github.com/Nessex))

- Kube-apiserver: errors decoding objects in etcd are now recorded in an `apiserver_storage_decode_errors_total` counter metric ([#114376](https://github.com/kubernetes/kubernetes/pull/114376), [@baomingwang](https://github.com/baomingwang)) [SIG API Machinery and Instrumentation]

  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
  in the namespace of the pod and a `kubelet_lifecycle_handler_http_fallbacks_total`
  metric in the kubelet is incremented. Cluster administrators can opt out of the
  expanded lifecycle handler capabilities by setting

* Allows changing nodeName in endpoint update. ([#68575](https://github.com/kubernetes/kubernetes/pull/68575), [@prameshj](https://github.com/prameshj))
* kube-apiserver would return 400 Bad Request when it couldn't decode a json patch. ([#68346](https://github.com/kubernetes/kubernetes/pull/68346), [@CaoShuFeng](https://github.com/CaoShuFeng))
    * kube-apiserver would return 422 Unprocessable Entity when a json patch couldn't be applied to one object.

- Fixed two scheduler metrics (pending_pods and schedule_attempts_total) not being recorded ([#87692](https://github.com/kubernetes/kubernetes/pull/87692), [@everpeace](https://github.com/everpeace)) [SIG Scheduling]
- Kubelet metrics have been changed to buckets.

- Demoted KEP-5278 feature gates `ClearingNominatedNodeNameAfterBinding` and `NominatedNodeNameForExpectation` to alpha from beta. ([#133293](https://github.com/kubernetes/kubernetes/pull/133293), [@utam0k](https://github.com/utam0k)) [SIG Scheduling and Testing]...

### Bug or Regression

- Disabled a previously on-by-default optimization for the API server where each **watch** response used a dedicated goroutine. The `APIServingWithRoutine` feature gate has been demoted from beta to alpha, and is now off by default.
