**API Change:**
- Upon receiving a LIST request with expired continue token, the apiserver now returns a continue token together with the 410 "the from parameter is too old " error. If the client does not care about getting a list from a consistent snapshot, the client can use this token to continue listing from the next key, but the returned chunk will be from the latest snapshot [kubernetes/kubernetes67284](https://github.com/kubernetes/kubernetes/pull/67284)
- Introduces autoscaling/v2beta2 and custom\_metrics/v1beta2, which implement metric selectors for Object and Pods metrics, as well as allowing AverageValue targets on Objects, similar to External metrics [kubernetes/kubernetes64097](https://github.com/kubernetes/kubernetes/pull/64097)

- RuntimeClass is a new API resource for defining different classes of runtimes
that may be used to run containers in the cluster. Pods can select a
RunitmeClass to use via the RuntimeClassName field. This feature is in alpha,
and the RuntimeClass feature gate must be enabled in order to use it [kubernetes/kubernetes67737](https://github.com/kubernetes/kubernetes/pull/67737)
- The PodShareProcessNamespace feature to configure PID namespace sharing within
a pod has been promoted to beta [kubernetes/kubernetes66507](https://github.com/kubernetes/kubernetes/pull/66507)
- To address the possibility dry-run requests overwhelming admission webhooks that rely on side effects and a reconciliation mechanism, a new field is being added to admissionregistration.k8s.io/v1beta1.ValidatingWebhookConfiguration and admissionregistration.k8s.io/v1beta1.MutatingWebhookConfiguration so that webhooks can explicitly register as having dry-run support. If a dry-run request is made on a resource that triggers a non dry-run supporting webhook, the request will be completely rejected, with "400: Bad Request". Additionally, a new field is being added to the admission.k8s.io/v1beta1.AdmissionReview API object, exposing to webhooks whether or not the request being reviewed is a dry-run [kubernetes/kubernetes66936](https://github.com/kubernetes/kubernetes/pull/66936)
