- Property `conditions` in `apiextensions.v1beta1.CustomResourceDefinitionStatus` and `apiextensions.v1.CustomResourceDefinitionStatus` is now optional instead of required. ([#64996](https://github.com/kubernetes/kubernetes/pull/64996), [@roycaihw](https:/...

* API server properly parses propagationPolicy as a query parameter sent with a delete request ([#63414](https://github.com/kubernetes/kubernetes/pull/63414), [@roycaihw](https://github.com/roycaihw))

### Other notable changes

* CustomResourceDefinitions: OpenAPI v3 validation schemas containing `$ref`references are no longer permitted (valid references could not be constructed previously because property ids were not permitted either). Before upgrading, ensure CRD definitions do not include those `$ref` fields. ([#58438](https://github.com/kubernetes/kubernetes/pull/58438), [@carlory](https://github.com/carlory))

* Orphaned routes are properly removed from terminated instances. ([#56258](https://github.com/kubernetes/kubernetes/pull/56258), [@databus23](https://github.com/databus23))

* OpenStack Cinder will now detach properly when Nova is shut down. ([#56846](https://github.com/kubernetes/kubernetes/pull/56846), [@zetaab](https://github.com/zetaab))

- Corrected the documentation for escaping dollar signs in a container's env, command and args property. ([#101916](https://github.com/kubernetes/kubernetes/pull/101916), [@MartinKanters](https://github.com/MartinKanters)) [SIG Apps]

* The CRD handler now properly re-creates stale CR storage to reflect CRD update. ([#79114](https://github.com/kubernetes/kubernetes/pull/79114), [@roycaihw](https://github.com/roycaihw))
