- Published OpenAPI for the StatefulSet schema is corrected to indicate the `.spec.serviceName` is optional. ([#130233](https://github.com/kubernetes/kubernetes/pull/130233), [@soltysh](https://github.com/soltysh)) [SIG API Machinery, Apps and Testing]

- Add the `timezone` field to the cronjob describe output. ([#136663](https://github.com/kubernetes/kubernetes/pull/136663), [@kfess](https://github.com/kfess)) [SIG CLI]
- Add the ability for statefulset controller to read its own pod and pvc writes ([#137254](https://github.com/kubernetes/kubernetes/pull/137254), [@michaelasp](https://github.com/michaelasp)) [SIG Apps]

### Bug or Regression

- StatefulSets should always count `.status.availableReplicas` at the correct time without a delay. This results in faster progress of StatefulSet rollout. ([#136097](https://github.com/kubernetes/kubernetes/pull/136097), [@atiratree](https://github.com/atiratree)) [SIG Apps]
