   * The basic strategy is to subdivide the table among Segments, each of which itself is a
   * concurrently readable hash table. The map supports non-blocking reads and concurrent writes
   * across different segments.
   *
   * The page replacement algorithm's data structures are kept casually consistent with the map. The
   * ordering of writes to a segment is sequentially consistent. An update to the map and recording

* kubectl now supports validation of nested objects with different ApiGroups (e.g. objects in a List) ([#25172](https://github.com/kubernetes/kubernetes/pull/25172), [@pwittrock](https://github.com/pwittrock))

* Azure file persistent volumes can use a new `secretNamespace` field to reference a secret in a different namespace than the one containing their bound persistent volume claim. The azure file persistent volume provisioner honors a corresponding `secretNamespace` storage class parameter to determine where to place secrets containing the storage account...

### Bug or Regression

- Fix a scheduler preemption issue where the victim pod was not deleted due to incorrect status patching. This issue occurred when the preemptor and victim pods had different QoS classes in their status, causing the preemption to fail entirely.

- For volumes that allow attaches across multiple nodes, attach and detach operations across different nodes are now executed in parallel. ([#89240](https://github.com/kubernetes/kubernetes/pull/89240), [@verult](https://github.com/verult)) [SIG Apps, Node and Storage]
