- If scheduling fails on PreBind or Bind, scheduler will retry the failed pod immediately after backoff time, regardless of the reason for failing. In this case EventsToRegister (QHints) will not be taken into consideration before retry.

	c.Assert(err, nil)

	// The reason to duplicate this structure here is to verify if the
	// unmarshalling works from a client perspective, specifically
	// while unmarshalling time.Time type for 'Initiated' field.

- 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...

- Append the image pull error for the pods `status.containerStatuses[*].state.waiting.message` when
  in image pull back-off (`reason` is `ImagePullBackOff`) instead of the generic `Back-off pulling image…` message. ([#127918](https://github.com/kubernetes/kubernetes/pull/127918), [@saschagrunert](https://github.com/saschagrunert)) [SIG Node and Testing]

### Documentation

- Documented the reason field in CRI API to ensure it equals `OOMKilled` for the containers terminated by OOM killer ([#112977](https://github.com/kubernetes/kubernetes/pull/112977), [@mimowo](https://github.com/mimowo))

### Added metrics

- Added metrics `aggregator_openapi_v2_regeneration_count`, `aggregator_openapi_v2_regeneration_gauge` and `apiextension_openapi_v2_regeneration_count` counting the triggering APIService and CRDs and the reason (add, update, delete) when kube-apiserver regenerates the OpenAPI spec.

- The PR adds functionality to generate events when a PV or PVC processing encounters certain failures. The events help users to know the reason for the failure so they can take necessary recovery actions. ([#89845](https://github.com/kubernetes/kubernetes/pull/89845), [@yuga711](https://github.com/yuga711)) [SIG Apps]

* A new predicates, named 'CheckNodeCondition', was added to replace node condition filter. 'NetworkUnavailable', 'OutOfDisk' and 'NotReady' maybe reported as a reason when failed to schedule pods. ([#51117](https://github.com/kubernetes/kubernetes/pull/51117), [@k82cn](https://github.com/k82cn))
