- Fixes an issue that can result in namespaced custom resources being orphaned when their namespace is deleted, if the CRD defining the custom resource is removed concurrently with namespaces being deleted, then recreated.

This release contains changes that address the following vulnerabilities:

### CVE-2022-3162: Unauthorized read of Custom Resources

A security issue was discovered in Kubernetes where users authorized to list or watch one type of namespaced custom resource cluster-wide can read custom resources of a different type in the same API group they are not authorized to read.

**Affected Versions**:

os.Hostname() will be used, in that order. ([#56812](https://github.com/kubernetes/kubernetes/pull/56812), [@dims](https://github.com/dims))

* Custom resources can be listed with a set of grouped resources (category) by specifying the categories in the [CustomResourceDefinition spec](https://kubernetes.io/docs/tasks/access-kubernetes-api/extend-api-custom-resource-definitions/#categories). Example: They can be used with `kubectl get important`, where `important` is a category. ([#59561](https://...

   * {@linkplain Service.State#TERMINATED terminates} or {@linkplain Service.State#TERMINATED
   * fails}. Subclasses may override this method to supply a custom {@link ScheduledExecutorService}
   * instance. This method is guaranteed to only be called once.
   *
   * <p>By default this returns a new {@link ScheduledExecutorService} with a single thread pool

- API paging is now enabled for custom resource definitions, custom resources and APIService objects. ([#67861](https://github.com/kubernetes/kubernetes/pull/67861), [@liggitt](https://github.com/liggitt))

- Fixes an issue that can result in namespaced custom resources being orphaned when their namespace is deleted, if the CRD defining the custom resource is removed concurrently with namespaces being deleted, then recreated. ([#93790](https://github.com/kubernetes/kubernetes/pull/93790), [@liggitt](https://github.com/liggitt)) [SIG API Machinery...

and specified for [deprecated versions of custom resources](https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definition-versioning/#version-deprecation).

## Benutzerdefinierte Validierung { #custom-validation }

Es kann Fälle geben, in denen Sie eine **benutzerdefinierte Validierung** durchführen müssen, die nicht mit den oben gezeigten Parametern durchgeführt werden kann.

But you can also provide other alternative `servers`, for example if you want *the same* docs UI to interact with both a staging and a production environment.

If you pass a custom list of `servers` and there's a `root_path` (because your API lives behind a proxy), **FastAPI** will insert a "server" with this `root_path` at the beginning of the list.

For example:
