StatefulSets with the annotation set to `false` will become active after upgrading.

* The CronJob object is now enabled by default at `v1beta1`. CronJob `v2alpha1` is still available, but it must be explicitly enabled. We recommend that you move any current CronJob objects to `batch/v1beta1.CronJob`. Be aware that if you specify the deprecated version, you may encounter Resource Not Found errors. These errors occur because the new controllers look for the new version during a rolling update....
