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.

* The `batch/v2alpha1.ScheduledJob` was removed. Migrate to `batch/v1beta.CronJob` to continue managing time...
