- Added a new `storage_operation_status_count` metric for kube-controller-manager and kubelet to count success and error statues. ([#75750](https://github.com/kubernetes/kubernetes/pull/75750), [@msau42](https://github.com/msau42))

### Deprecated/changed metrics

 * mask of the ACE, the whole access check fails. If the ACE is an "allow"
 * ACE and <i>all</i> of the bits in the desired access bits match bits in
 * the access mask of the ACE, the access check is successful. Otherwise,
 * more ACEs are evaluated until all desired access bits (combined)
 * are "allowed". If all of the desired access bits are not "allowed"

## NOTE

- Empty delete markers (such as for objects with no other successor versions) do not transition to the new pool to avoid creating empty metadata on the other pool(s). If you believe transitioning empty delete markers is required, open a GitHub issue.
