before.
	2. In Namespaces that previously did not have the "DefaultDeny"
	   annotation, you should delete any existing NetworkPolicy
	   objects. These would have had no effect before, but with v1
	   semantics they might cause some traffic to be blocked that you
	   didn't intend to be blocked.

### Other notable changes

    * This is a breaking change (and only slightly) if you used dependencies with `yield`, used `except` in those dependencies, and didn't raise again.

- Fix: statle smb mount issue when smb file share is deleted and then unmount ([#121851](https://github.com/kubernetes/kubernetes/pull/121851), [@andyzhangx](https://github.com/andyzhangx)) [SIG Storage]
- The scheduling queue didn't notice any extenders' failures, it could miss some cluster events,
  and it could end up Pods rejected by Extenders stuck in unschedulable pod pool in 5min in the worst-case scenario.

- The Scheduler did not run the plugin Score method when its PreScore method returned a Skip status. In other words, the PreScore/Score plugin could return a Skip status in PreScore if the plugin did nothing in Score for that Pod.

- Updated `kube-openapi` to remove invalid defaults: OpenAPI spec no longer includes default of `{}` for certain fields where it did not make sense. ([#120757](https://github.com/kubernetes/kubernetes/pull/120757), [@alexzielenski](https://github.com/alexzielenski))
