 - `IndexedJob`: Allows the [Job](/docs/concepts/workloads/controllers/job/)

+- `JobTrackingWithFinalizers`: Enables tracking [Job](/docs/concepts/workloads/controllers/job)

+  The Job controller uses Pod finalizers and a field in the Job status to keep

 - `IngressClassNamespacedParams`: Allow namespace-scoped parameters reference in
   `IngressClass` resource. This feature adds two fields - `Scope` and `Namespace`
   to `IngressClass.spec.parameters`.
