- The apiserver debug endpoint `/debug/api_priority_and_fairness/dump_requests` has been extended to dump executing requests as well as queued ones.  A column for StartTime has been added to the returned table, with the queued requests having a StartTime of "0001-01-01T00:00:00Z".  The executing requests have a RequestIndexInQueue of -1, and the QueueIndex is also -1 for priority levels without queues. ([#119009](https://github.com/kubernetes/kubernetes/pull/119009),...

- The API server now re-uses data encryption keys while the kms v2 plugin key ID is stable.
