- When using a claim with immediate allocation and a pod referencing that claim couldn't get scheduled, the scheduler incorrectly may have tried to deallocate that claim. ([#122415](https://github.com/kubernetes/kubernetes/pull/122415), [@pohly](https://github.com/pohly))

* OIDC authentication now allows tokens without an "email_verified" claim when using the "email" claim. If an "email_verified" claim is present when using the "email" claim, it must be `true`. ([#61508](https://github.com/kubernetes/kubernetes/pull/61508), [@rithujohn191](https://github.com/rithujohn191))

- Added a config-mode flag in azure auth module to enable getting AAD token without spn: prefix in audience claim. When it's not specified, the default behavior doesn't change. ([#87630](https://github.com/kubernetes/kubernetes/pull/87630), [@weinong](https://github.com/weinong)) [SIG API Machinery, Auth, CLI and Cloud Provider]

- `kube-apiserver` added:

- Dynamic Resource Allocation (DRA): using structured parameters with a claim that gets reused between pods may have led to a claim with an invalid state (allocated without a finalizer) which then caused scheduling of pods using the claim to stop. ([#124931](https://github.com/kubernetes/kubernetes/pull/124931), [@pohly](https://github.com/pohly)) [SIG Node and Scheduling]

- Dynamic resource allocation: when a claim uses "wait for first consumer" allocation (the default), then it will now get deallocated after it was used by a pod. That ensures that the next pod isn't affected by previous scheduling decision and that resources are not kept allocated unless really needed. If keeping a claim allocated is desired, use "immediate allocation." ([#118936](https://github.com/kubernetes/kubernetes/pull/118936),...

  ([#81210](https://github.com/kubernetes/kubernetes/pull/81210), [@figo](https://github.com/figo))
- kubelet now exports an `kubelet_evictions` metric that counts the number of pod evictions carried out by the kubelet to reclaim resources ([#81377](https://github.com/kubernetes/kubernetes/pull/81377), [@sjenning](https://github.com/sjenning))

### Removed metrics

* [stable] You can now specify the World Wide Identifier (WWID) for the volume identifier in the Fibre Channel volume plugin.

* [beta] Reclaim policy in StorageClass

  * You can now configure the reclaim policy in StorageClass, instead of defaulting to `delete` for dynamically provisioned volumes.

* [alpha] Volume resizing

* The recycling reclaim policy has been deprecated. Users should use dynamic provisioning instead. ([#59063](https://github.com/kubernetes/kubernetes/pull/59063), [@ayushpateria](https://github.com/ayushpateria))
