* [https://github.com/kubernetes/kubernetes/issues/49213](https://github.com/kubernetes/kubernetes/issues/49213) sig-cluster-lifecycle has decided to phase out the cluster/ directory over the next couple of releases in favor of deployment automations maintained outside of the core repo and outside of kubernetes orgs.

- Kube-apiserver: DELETECOLLECTION API requests are now recorded in metrics with the correct verb. ([#113133](https://github.com/kubernetes/kubernetes/pull/113133), [@sxllwx](https://github.com/sxllwx)) [SIG API Machinery]

- Resolves non-deterministic behavior of the garbage collection controller when ownerReferences with incorrect data are encountered. Events with a reason of `OwnerRefInvalidNamespace` are recorded when namespace mismatches between child and owner objects are detected. The [kubectl-check-ownerreferences](https://github.com/kubernetes-sigs/kubectl-check-ownerreferences) tool can be run prior to upgrading to locate existing objects with invalid...

- 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))

  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

- 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]
