* Restored old behavior to the `--template` flag in `get.go`. In old releases, providing a `--template` flag value and no `--output` value implicitly assigned a default value ("go-template") to `--output`, printing using the provided template argument.

- Api: validation of a `PodSpec` now rejects invalid `ResourceClaim` and `ResourceClaimTemplate` names. For a pod, the name generated for the `ResourceClaim` when using a template also must be valid.

### Bug or Regression

- Add missing `--kube-api-content-type` in kubemark hollow template ([#98911](https://github.com/kubernetes/kubernetes/pull/98911), [@Jeffwan](https://github.com/Jeffwan)) [SIG Scalability and Testing]

- Kubeadm: implemented structured output of 'kubeadm token list' in JSON, YAML, Go template and JsonPath formats ([#78764](https://github.com/kubernetes/kubernetes/pull/78764), [@bart0sh](https://github.com/bart0sh))

 apply` and strategic merge patch. You must explicitly set the spec.selector value
 in your manifest. An object with a spec.selector value that does not match the labels in
 its spec.template is invalid.

 - Selector mutation is disabled for all kinds in the
 app/v1beta2 group version, because the controllers in the workloads API do not handle
 selector mutation in

images. This option allows for precise image pull policy specification for master nodes and thus for more tight control over images. It is useful in CI environments and in environments, where the user has total control over master VM templates (thus, the master VM templates can be preloaded with the required Docker images for the control plane services).

### API Change

- Revert regression that prevented client-go latency metrics to be reported with a template URL to avoid label cardinality. ([#112056](https://github.com/kubernetes/kubernetes/pull/112056), [@aanm](https://github.com/aanm)) [SIG API Machinery]
