- The GA `PodPriority` feature gate is now on by default and cannot be disabled. The feature gate will be removed in v1.18. ([#79262](https://github.com/kubernetes/kubernetes/pull/79262), [@draveness](https://github.com/draveness))

  * The `--audit-policy-file` option is required if the `AdvancedAuditing` feature is not explicitly turned off (`--feature-gates=AdvancedAuditing=false`) on the API server.
  * The audit log file defaults to JSON encoding when using the advanced auditing feature gate.
  * An audit policy file without either an `apiVersion` or a `kind` field may be treated as invalid.

*   Apply algorithm in scheduler by feature gates. ([#52723](https://github.com/kubernetes/kubernetes/pull/52723),[ @k82cn](https://github.com/k82cn))

### Scheduling

- This PR will introduce a feature gate CSIServiceAccountToken with two additional fields in `CSIDriverSpec`. ([#93130](https://github.com...

- The `WarningHeaders` feature gate that is GA since v1.22 is unconditionally enabled, and can no longer be specified via the `--feature-gates` argument. ([#108394](https://github.com/kubernetes/kubernetes/pull/108394), [@ialidzhikov](https://github.com/ialidzhikov))

- The `DefaultIngressClass` feature is now GA. The `--feature-gate` parameter will be removed in 1.20. ([#91957](https://github.com/kubernetes/kubernetes/pull/91957), [@cmluciano](https://github.com/cmluciano)) [SIG API Machinery, Apps, Network and Testing]

* On COS, NPD creates a node condition for frequent occurrences of unregister_netdevice ([#65342](https://github.com/kubernetes/kubernetes/pull/65342), [@dashpole](https://github.com/dashpole))
* bugfix: Do not print feature gates in the generic apiserver code for glog level 0 ([#65584](https://github.com/kubernetes/kubernetes/pull/65584), [@neolit123](https://github.com/neolit123))

- The GCERegionalPersistentDisk feature gate (GA in 1.13) can no longer be disabled. The feature gate will be removed in v1.17. ([#77412](https://github.com/kubernetes/kubernetes/pull/77412), [@liggitt](https://github.com/liggitt))

* getDeviceNameFromMount() function doesn't return the volume path correctly when the volume path contains spaces [#37712](https://github.com/kubernetes/kubernetes/issues/37712)
* Federation alpha features do not have feature gates defined and
are hence enabled by default. This will be fixed in a future release.
[#38593](https://github.com/kubernetes/kubernetes/issues/38593)
