- `k8s.io/dynamic-resource-allocation/controller`: `ResourceClaimParameters` and `ResourceClassParameters` validation errors are now visible on `ResourceClaim`, `ResourceClass` and `Pod`. ([#121065](https://github.com/kubernetes/kubernetes/pull/121065), [@byako](https://github.com/byako))
- `k8s.io/dynamic-resource-allocation`: can now handle a `selected` node which isn't listed

- `resource.k8s.io/v1alpha1` was replaced with `resource.k8s.io/v1alpha2`. Before
  upgrading a cluster, all objects in resource.k8s.io/v1alpha1 (ResourceClaim, ResourceClaimTemplate,
  ResourceClass, PodScheduling) must be deleted. The changes are internal, so
  YAML files which create pods and resource claims don't need changes except for

										Default: map[string]interface{}{},
										Ref:     ref("k8s.io/api/resource/v1alpha2.ResourceClass"),
