Although *v1.9* is still compatible, we recommend upgrading to one of the supported versions.
All prior versions of docker will not be supported.

#### ThirdPartyResource

If you use ThirdPartyResource objects, they have moved from being namespaced-scoped to be cluster-scoped. Before upgrading to 1.3.0, export and delete any existing ThirdPartyResource objects using a 1.2.x client:

kubectl get thirdpartyresource --all-namespaces -o yaml > tprs.yaml

    - [seccomp graduates to General Availability](#seccomp-graduates-to-general-availability)
    - [Production images moved to community control](#production-images-moved-to-community-control)
    - [KubeSchedulerConfiguration graduates to Beta](#kubeschedulerconfiguration-graduates-to-beta)

### Other (Cleanup or Flake)

  - `spec.additionalPrinterColumns` is removed in v1; use `spec.versions[*].additionalPrinterColumns` instead
  - `spec.conversion.webhookClientConfig` is moved to `spec.conversion.webhook.clientConfig` in v1
  - `spec.conversion.conversionReviewVersions` is moved to `spec.conversion.webhook.conversionReviewVersions` in v1
  - `spec.versions[*].schema.openAPIV3Schema` is now required when creating v1 CustomResourceDefinitions

#### Additional Notable Feature Updates
- Support for go modules in Kubernetes Core.
- Continued preparation for cloud provider extraction and code organization.  The cloud provider code has been moved to kubernetes/legacy-cloud-providers for easier removal later and external consumption.
- Kubectl [get and describe](https://github.com/kubernetes/enhancements/issues/515) now works with extensions

### Other (Cleanup or Flake)

- Scheduler framework interface moved from pkg/scheduler/framework/v1alpha to pkg/scheduler/framework ([#95069](https://github.com/kubernetes/kubernetes/pull/95069), [@farah](https://github.com/farah)) [SIG Scheduling, Storage and Testing]

- The storage.k8s.io/CSIDriver has moved to GA, and is now available for use. ([#84814](https://github.com/kubernetes/kubernetes/pull/84814), [@huffmanca](https://github.com/huffmanca)) [SIG API Machinery, Apps, Auth, Node, Scheduling, Storage and Testing]

* The shortcuts that were moved server-side in at least 1.9 have been removed from being hardcoded in kubectl. This means that the client-based restmappers have been moved to client-go, where everyone who needs them can have access.
