- [`KT-59588`](https://youtrack.jetbrains.com/issue/KT-59588) Upgrade max gradle version to max supported in kapt connected tests

* Bugfix: OpenAPI models may not get group-version-kind extension if kubernetes is vendored in another project (e.g. minikube). Kubectl 1.8 needs this extension to work with those projects. ([#53152](https://github.com/kubernetes/kubernetes/pull/53152), [@mbohlool](https://github.com/mbohlool))

### Auth

### Autoscaling

 - Consuming metrics directly from Heapster is deprecated in favor of
   consuming metrics via an aggregated version of the resource metrics API.

   - In version 1.8, enable this behavior by setting the
     `--horizontal-pod-autoscaler-use-rest-clients` flag to `true`.

* Kubectl explain now prints out the Kind and API version of the resource being explained. ([#55689](https://github.com/kubernetes/kubernetes/pull/55689), [@luksa](https://github.com/luksa))

### Cluster Lifecycle

* The default Kubernetes version for kubeadm is now 1.10. ([#61127](https://github.com/kubernetes/kubernetes/pull/61127), [@timothysc](https://github.com/timothysc))

- Implement `post-filter` extension point for scheduling framework ([#78097](https://github.com/kubernetes/kubernetes/pull/78097), [@draveness](https://github.com/draveness))
- Add Bind extension point of the scheduling framework ([#78513](https://github.com/kubernetes/kubernetes/pull/78513), [@chenchun](https://github.com/chenchun))

* kube-apiserver now includes all registered API groups in discovery, including registered extension API group/versions for unavailable extension API servers. ([#66932](https://github.com/kubernetes/kubernetes/pull/66932), [@nilebox](https://github.com/nilebox))

    /** The key of the configuration. e.g. _id */
    String INDEX_FIELD_ID = "index.field.id";

    /** The key of the configuration. e.g. _version */
    String INDEX_FIELD_VERSION = "index.field.version";

    /** The key of the configuration. e.g. _seq_no */
    String INDEX_FIELD_seq_no = "index.field.seq_no";

    /** The key of the configuration. e.g. _primary_term */

* `edit` now supports Third party resources and extension API servers. ([#41304](https://github.com/kubernetes/kubernetes/pull/41304), [@liggitt](https://github.com/liggitt))
  * Now to edit a particular API version, provide the fully-qualify the resource, version, and group used to fetch the object (for example, `job.v1.batch/myjob`)
  * Client-side conversion is no longer done, and the `--output-version` option is deprecated for `kubectl edit`.

- The resource version option, when passed to a list call, is now consistently interpreted as the minimum allowed resource version.  Previously when listing resources that had the watch cache disabled clients could retrieve a snapshot at that exact resource version.  If the client requests a resource version newer than the current state, a TimeoutError is returned suggesting the client retry in a few seconds....
