### Autoscaling
* **[alpha]** The Horizontal Pod Autoscaler now supports drawing metrics through the API server aggregator.
* **[alpha]** The Horizontal Pod Autoscaler now supports scaling on multiple, custom metrics.
* Cluster Autoscaler publishes its status to kube-system/cluster-autoscaler-status ConfigMap.
* Cluster Autoscaler can continue operations while some nodes are broken or unready.

* Update Cluster Autoscaler to 1.13.4 ([#77065](https://github.com/kubernetes/kubernetes/pull/77065), [@losipiuk](https://github.com/losipiuk))

[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
the Cluster Autoscaler, which provides improved performance and error reporting.

#### Cluster Autoscaling
* Cluster Autoscaler 0.6. More information available [here](https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/README.md).

* cluster-autoscaler: Fix duplicate writing of logs. ([#45017](https://github.com/kubernetes/kubernetes/pull/45017), [@MaciekPytel](https://github.com/MaciekPytel))
