- If the feature-gate VolumeAttributesClass is enabled, when finding a suitable persistent volume for a claim, the kube-controller-manager will be aware of the `volumeAttributesClassName` field of PVC and PV objects. The `volumeAttributesClassName` field is a reference to a VolumeAttributesClass object, which contains a set of key-value pairs that present mutable attributes of the volume. It's forbidden to change the `volumeAttributesClassName` field of a PVC object...

* `kubectl api-resources` now supports filtering to resources supporting specific verbs, and can output fully qualified resource names suitable for combining with commands like `kubectl get` ([#63254](https://github.com/kubernetes/kubernetes/pull/63254), [@liggitt](https://github.com/liggitt))

- Removed the `CronJobTimeZone` feature gate (the feature is stable and always enabled)
  - Removed the `JobMutableNodeSchedulingDirectives` feature gate (the feature is stable and always enabled)

These conversions also apply to type parameters with suitable core types.
Determine if we can simply use core type instead of underlying type here,
of if the general conversion rules take care of this.

- Graduating `pending_pods`, `preemption_attempts_total`, `preemption_victims` and `schedule_attempts_total` metrics to stable. Also `e2e_scheduling_duration_seconds` is renamed to `scheduling_attempt_duration_seconds` and the latter is graduated to stable. (#105941, @rezakrimi) [SIG Instrumentation, Scheduling and Testing]

* [stable] Support Attach and Detach operations for ReadWriteOnce (RWO) volumes that use iSCSI and Fibre Channel plugins.

* [stable] Expose storage usage metrics

  * The available capacity of a given Persistent Volume (PV) is available by calling the Kubernetes metrics API.

* [stable] Volume plugin metrics

- Relaxed API validation to allow pod node selector to be mutable for gated pods (additions only, no deletions or mutations). ([#116161](https://github.com/kubernetes/kubernetes/pull/116161), [@danielvegamyhre](https://github.com/danielvegamyhre))

### Volumes
* **[stable]** StorageClass API is promoted to v1 (storage.k8s.io/v1).
* **[stable]** Default storage classes are deployed during installation on Azure, AWS, GCE, OpenStack and vSphere.
* **[stable]** Added ability to populate environment variables from a configmap or secret.

### Other (Cleanup or Flake)

- Apiserver_request_duration_seconds is promoted to stable status. ([#99925](https://github.com/kubernetes/kubernetes/pull/99925), [@logicalhan](https://github.com/logicalhan)) [SIG API Machinery, Instrumentation and Testing]
