* Introduce Alpha field `AllowWatchBookmarks` in ListOptions for requesting watch bookmarks from apiserver. The implementation in apiserver is hidden behind feature gate `WatchBookmark` (currently in Alpha stage).
* Override protocol between etcd server and kube-apiserver on master with HTTPS instead HTTP when mTLS is enabled in GCE ([#74690](https://github.com/kubernetes/kubernetes/pull/74690), [@wenjiaswe](https://github.com/wenjiaswe))

### Other notable changes

PID Limits features are now generally available on both `SupportNodePidsLimit` (node-to-pod PID isolation) and `SupportPodPidsLimit` (ability to limit PIDs per pod), after being enabled-by-default in beta stage for a year.

### API Priority and Fairness graduates to Beta

### Bug or Regression

- Fix missing delete events on informer re-lists to ensure all delete events are correctly emitted and using the latest known object state, so that all event handlers and stores always reflect the actual apiserver state as best as possible ([#115899](https://github.com/kubernetes/kubernetes/pull/115899), [@odinuge](https://github.com/odinuge)) [SIG API Machinery]

- Adding a set of debugging endpoints under prefix "/debug/flowcontrol/*" for dumping internal states of flow-control system with different granularity. ([#90967](https://github.com/kubernetes/kubernetes/pull/90967), [@yue9944882](https://github.com/yue9944882)) [SIG API Machinery]
