A conversion changes the <a href="#Types">type</a> of an expression

A conversion may appear literally in the source, or it may be <i>implied</i>

- Fixes conversion error for HorizontalPodAutoscaler objects with invalid annotations ([#89969](https://github.com/kubernetes/kubernetes/pull/89969), [@liggitt](https://github.com/liggitt)) [SIG Autoscaling]

  * 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`.
* `edit` works as intended with apply and will not change the annotation

### Apps

The core workloads API, which is composed of the DaemonSet, Deployment, ReplicaSet, and StatefulSet kinds, has been promoted to GA stability in the apps/v1 group version. As such, the apps/v1beta2 group version is deprecated, and all new code should use the kinds in the apps/v1 group version.

### 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`.

- [`KT-55879`](https://youtrack.jetbrains.com/issue/KT-55879) Modularized tests: fir.bench.language.version is used as API version, not language version
- [`KT-51821`](https://youtrack.jetbrains.com/issue/KT-51821) ClassCastException on anonymous fun interface implementation when unrelated vararg is used

* 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))

- 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....

* kubectl: This client version requires the `apps/v1` APIs, so it will not work against a cluster version older than v1.9.0. Note that kubectl only guarantees compatibility with clusters that are +/-1 minor version away. ([#61419](https://github.com/kubernetes/kubernetes/pull/61419), [@enisoc](https://github.com/enisoc))
