- Graduated the `WinDSR` feature in the kube-proxy to beta. The `WinDSR` feature gate is now enabled by default. ([#130876](https://github.com/kubernetes/kubernetes/pull/130876), [@rzlink](https://github.com/rzlink)) [SIG Windows]
- Graduated the asynchronous preemption feature in the scheduler to beta. 

 *   <li>least-recently-used eviction when a maximum size is exceeded (note that the cache is
 *       divided into segments, each of which does LRU internally)
 *   <li>time-based expiration of entries, measured since last access or last write
 *   <li>keys automatically wrapped in {@code WeakReference}
 *   <li>values automatically wrapped in {@code WeakReference} or {@code SoftReference}

### CSI Service Account Token

CSI Service Account Token feature moves to Beta in 1.21. This feature improves the security posture and allows CSI drivers to receive pods' [bound service account tokens](https://github.com/kubernetes/enhancements/blob/master/keps/sig-auth/1205-bound-service-account-tokens/README.md). This feature also provides a knob to re-publish volumes so that short-lived volumes can be refreshed.

- Add a StorageVersionAPI feature gate that makes API server update storageversions before serving certain write requests. 
  This feature allows the storage migrator to manage storage migration for built-in resources.
