### SIG Autoscaling

[SIG Autoscaling][] is responsible for autoscaling-related components,
such as the Horizontal Pod Autoscaler and Cluster Autoscaler.

For the 1.8 release, SIG Autoscaling continued to focus on stabilizing
features introduced in previous releases: the new version of the
Horizontal Pod Autoscaler API, which supports custom metrics, and

- Continued streaming kubelet logs when the CRI server of the runtime was unavailable. ([#124025](https://github.com/kubernetes/kubernetes/pull/124025), [@saschagrunert](https://github.com/saschagrunert)) [SIG Node]

server-side printing and its support in kubectl, as well as finishing [kubectl diff which is based on server-side dry-run feature](https://kubernetes.io/docs/concepts/overview/working-with-objects/object-management/#how-to-create-objects). We’ve continued separating kubectl code to prepare for extraction out of main repository. Finally, thanks to the awesome support and feedback from community we’ve managed to promote the new [plugin mechanism to Beta](https://kubernetes.io/docs/tasks/extend-kube...

### Windows

- [Extensions](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cloud-provider/991-cloud-controller-migration/README.md) for Cloud Controller Manager Migration.
- Continued deprecation of extensions/v1beta1, apps/v1beta1, and apps/v1beta2 APIs; these extensions will be retired in 1.16!

## Known Issues

Linux kernel cgroups v2 API was declared stable. With some distributions now defaulting to this API, Kubernetes must support it to continue operating on those distributions. cgroups v2 offers several improvements over cgroups v1, for more information see the [cgroups v2](https://kubernetes.io/docs/concepts/architecture/cgroups/) documentation. While cgroups v1 will continue to be supported, this enhancement puts Kubernetes to be ready for eventual deprecation and replacement in favor of v2.
