  - support for the `v1alpha3` configuration file format is deprecated and will be removed in 1.14. Use `kubeadm config migrate` to migrate `v1alpha3` configuration files to `v1beta1`, which provides improvements in image repository management, addons configuration, and other areas. The documentation for `v1beta1` can be found here: https://godoc.org/k8s.io/kubernetes/cmd/kubea...

- The beta `PodSecurityPolicy` admission plugin, deprecated since 1.21, is removed. Follow the instructions at https://kubernetes.io/docs/tasks/configure-pod-container/migrate-from-psp/ to migrate to the built-in PodSecurity admission plugin (or to another third-party  policy webhook) prior to upgrading to v1.25. ([#109798](https://github.com/kubernetes/kubernetes/pull/109798), [@liggitt](https://github.com/liggitt))

As far as Sig Instrumentation, the major change in Kubernetes 1.11 is the deprecation of Heapster as part of ongoing efforts to move to the new Kubernetes monitoring model. Clusters still using Heapster for autoscaling should be migrated over to metrics-server and the custom metrics API. See the deprecation section for more information.

### SIG Network

- API
  - Ingress resources will no longer be served from `extensions/v1beta1` in v1.19. Migrate use to the `networking.k8s.io/v1beta1` API, available since v1.14. Existing persisted data can be retrieved via the `networking.k8s.io/v1beta1` API.
