Please note that the unknown fields will not be pruned when migrating from `apiextensions.k8s.io/v1beta1` to `apiextensions.k8s.io/v1` CRDs.

### Kubernetes Ingress
Traefik v2.5 moves forward for the Ingress provider to support Kubernetes v1.22.
Traefik now supports only v1.14+ Kubernetes clusters, which means the support of `extensions/v1beta1` API Version ingresses has been dropped.
The `extensions/v1beta1` API Version should now be replaced either by `networking.k8s.io/v1beta1` or by `networking.k8s.io/v1` (as of Kubernetes v1.19+).
The support of the `networking.k8s.io/v1beta1` API Version will stop in Kubernetes v1.22.

it manages access to cluster services by supporting the [Ingress](https://kubernetes.io/docs/concepts/services-networking/ingress/) specification.
