- 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))

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

* [stable] Volume plugin metrics

- Fixed a bug that an init container with containerRestartPolicy with `Always` cannot update its state from terminated to non-terminated for the pod with restartPolicy with `Never` or `OnFailure`.

- Kubeadm will cleanup the stale data on best effort basis. Stale data will be removed when each reset phase are executed, default etcd data directory will be cleanup when the `remove-etcd-member` phase are executed.

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:...
