- Fixed missing delete events on informer re-lists to ensure all delete events were 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 ([#115620](https://github.com/kubernetes/kubernetes/pull/115620), [@odinuge](https://github.com/odinuge))

- Shrank the `OpenAPI v2` spec by more than 50%, especially for less CPU resource consumption. ([#118204](https://github.com/kubernetes/kubernetes/pull/118204), [@sttts](https://github.com/sttts))

if their volume source is of CSI type or they have a migrated annotation, when they are deleted, the PersistentVolume controller won't change their phase to the Failed state. With this patch, the external provisioner can remove the finalizer in the next reconcile loop. Unfortunately, if a previously existing PV has the Failed state, this patch won't take effect. Users are required to remove the finalizer manually. ([#122030](https://github.com/kubernetes/kubernetes/pull/122030), [@carlory](https:...
