a pointer type or type parameter. The unqualified type name acts as the field name.

<pre>
// A struct with four embedded fields of types T1, *T2, P.T3 and *P.T4
struct {
	T1        // field name is T1
	*T2       // field name is T2
	P.T3      // field name is T3
	*P.T4     // field name is T4
	x, y int  // field names are x and y

- Simplied validation error message for invalid fields by removing redundant field name. ([#132513](https://github.com/kubernetes/kubernetes/pull/132513), [@xiaoweim](https://github.com/xiaoweim)) [SIG API Machinery, Apps, Auth, Node and Scheduling]

  `hostAliases` fields to mark the fields used as keys in those lists as either defaulted
  or required. ([#124553](https://github.com/kubernetes/kubernetes/pull/124553), [@pmalek](https://github.com/pmalek))

  * Previously this would cause the command to fail regardless of whether or not the field was present in the object model
  * Now the command will succeed even if the sort-by field is missing from one or more of the objects

  If the `DeclarativeValidation` feature gate is enabled, mismatches with existing validation are reported via metrics.

 * kubeadm: The Token-related fields in the `MasterConfiguration` object have now been refactored. Instead of the top-level `.Token`, `.TokenTTL`, `.TokenUsages`, `.TokenGroups` fields, there is now a `BootstrapTokens` slice of `BootstrapToken` objects that support the same features under the `.Token`, `.TTL`, `.Usages`, `.Groups` fields. ([#64408](https://github.com/kubernetes/kubernetes/pull/64408), [@luxas](https://github.com/luxas))...

- The `metadata.clusterName` field is completely removed. This should not have any user-visible impact. ([#109602](https://github.com/kubernetes/kubernetes/pull/109602), [@lavalamp](https://github.com/lavalamp))

* ACTION REQUIRED: The Node.Status.Volumes.Attached.DevicePath field is now unset for CSI volumes. Update any external controllers that depend on this field. ([#75799](https://github.com/kubernetes/kubernetes/pull/75799), [@msau42](https://github.com/msau42))...

### API Change

- Added etcd_object_count metrics for CustomResources. ([#65983](https://github.com/kubernetes/kubernetes/pull/65983), [@sttts](https://github.com/sttts))
- The OpenAPI version field will now be properly autopopulated without needing other OpenAPI fields present in generic API server code. ([#66411](https://github.com/kubernetes/kubernetes/pull/66411), [@DirectXMan12](https://github.com/DirectXMan12))
