- Namespace is now included in the `--dry-run=client` output for `HorizontalPodAutoscaler (HPA)` objects. ([#134263](https://github.com/kubernetes/kubernetes/pull/134263), [@ardaguclu](https://github.com/ardaguclu)) [SIG CLI and Testing]
- Populated `involvedObject.apiVersion` on Events created for Nodes and Pods. ([#134545](https://github.com/kubernetes/kubernetes/pull/134545), [@novahe](https://github.com/novahe)) [SIG Cloud Provider, Network, Node, Scalability and Testing]

`container.seccomp.security.alpha.kubernetes.io`, deprecated since v1.19, was partially removed. Kubelets no longer support the annotations, use of the annotations in static pods is no longer supported, and the seccomp annotations are no longer auto-populated when pods with seccomp fields are created. Auto-population of the seccomp fields from the annotations is planned to be removed in 1.27. Pods  should use the corresponding pod or container `securityContext.seccompProfile` field instead.

* client-go: restores behavior of populating the BearerToken field in rest.Config objects constructed from kubeconfig files containing tokenFile config, or from in-cluster configuration. An additional BearerTokenFile field is now populated to enable constructed clients to periodically refresh tokens.
