* The namespace API object no longer supports the deletecollection operation, which was previously allowed by mistake and did not respect expected namespace lifecycle semantics. ([#47098](https://github.com/kubernetes/kubernetes/pull/47098), [@liggitt](https://github.com/liggitt))

- Sometimes, the scheduler incorrectly placed a pod in the "unschedulable" queue instead of the "backoff" queue. This happened when some plugin previously declared the pod as "unschedulable" and then in a later attempt encounters some other error. Scheduling of that pod then got delayed by up to five minutes, after which periodic flushing moved the pod back into the "active" queue. ([#120334](htt...

### Other notable changes

* CustomResourceDefinitions: OpenAPI v3 validation schemas containing `$ref`references are no longer permitted (valid references could not be constructed previously because property ids were not permitted either). Before upgrading, ensure CRD definitions do not include those `$ref` fields. ([#58438](https://github.com/kubernetes/kubernetes/pull/58438), [@carlory](https://github.com/carlory))

- Number of errors reported to the metric `storage_operation_duration_seconds_count` for emptyDir decreased significantly because previously one error was reported for each projected volume created. ([#117022](https://github.com/kubernetes/kubernetes/pull/117022), [@mpatlasov](https://github.com/mpatlasov)) [SIG Storage]

## Notable Changes to Existing Behavior

* Node controller no longer force-deletes pods from the api-server. ([#35235](https://github.com/kubernetes/kubernetes/pull/35235), [@foxish](https://github.com/foxish))
  * For StatefulSet (previously PetSet), this change means creation of
    replacement pods is blocked until old pods are definitely not running
    (indicated either by the kubelet returning from partitioned state,

- Fixes a regression in 1.23 where update requests to previously persisted `Service` objects that have not been modified since 1.19 can be rejected with an incorrect `spec.clusterIPs: Required value` error ([#107875](https://github.com/kubernetes/kubernetes/pull/107875), [@liggitt](https://github.com/liggitt))...
