- Kube-apiserver: fixed a conflict error encountered attempting to delete a pod with gracePeriodSeconds=0 and a resourceVersion precondition ([#85516](https://github.com/kubernetes/kubernetes/pull/85516), [@michaelgugino](https://github.com/michaelgugino)) [SIG API Machinery]

  In addition, when this feature is enabled, the 'details' field of 'Status' from the LIST response
  includes information that identifies the corrupt object(s).
  NOTE: unsafe deletion ignores finalizer constraints, and skips precondition checks.
  WARNING: this may break the workload associated with the resource being unsafe-deleted, if it relies on

- Fix a bug in the apiserver that could cause a valid update request to be rejected with a precondition check failure. ([#82303](https://github.com/kubernetes/kubernetes/pull/82303), [@roycaihw](https://github.com/roycaihw))
