- [`KTIJ-26501`](https://youtrack.jetbrains.com/issue/KTIJ-26501) K2: IDE K2: False positive unused import when declaration used for vararg parameter type

//     and the version of the actual struct is irrelevant.
//  5. We cannot easily change it.  Because this type is embedded in many locations, updates to this type
//     will affect numerous schemas.  Don't make new APIs embed an underspecified API type they do not control.
//
// Instead of using this type, create a locally provided and used type that is well-focused on your reference.

- Deprecate the instance type beta label (`beta.kubernetes.io/instance-type`) in favor of its GA equivalent: `node.kubernetes.io/instance-type` ([#82049](https://github.com/kubernetes/kubernetes/pull/82049), [@andrewsykim](https://github.com/andrewsykim))

    String CRAWLER_HOTTHREAD_TIMEOUT = "crawler.hotthread.timeout";

    /** The key of the configuration. e.g. cpu */
    String CRAWLER_HOTTHREAD_TYPE = "crawler.hotthread.type";

    /** The key of the configuration. e.g. resourceName,X-Parsed-By,Content-Encoding.*,Content-Type.*,X-TIKA.* */
    String CRAWLER_METADATA_CONTENT_EXCLUDES = "crawler.metadata.content.excludes";

Also, please note:
- using `application/vnd.kubernetes.protobuf` as the media storage type for 1.6 is default but not required
- the ability to rollback to etcd2 can be preserved by setting the storage media type flag on `kube-apiserver`

  ```
  --storage-media-type application/json
  ```

  to continue to use `application/json` as the storage media type which can be changed to
  `application/vnd.kubernetes.protobuf` at a later time.

    * If the serialization type is application/vnd.kubernetes.protobuf, and protobuf marshaling is not implemented for the requested API resource type, a '406 Not Acceptable is returned'.
    * If the serialization type is 'application/json':

* kube-apiserver: the default `--endpoint-reconciler-type` is now `lease`. The `master-count` endpoint reconciler type is deprecated and will be removed in 1.13. ([#63383](https://github.com/kubernetes/kubernetes/pull/63383), [@liggitt](https://github.com/liggitt))
