evicts pods from nodes in preparation for disruptive operations like kernel
upgrades or maintenance.
     * Custom Metrics for Autoscaling (HorizontalPodAutoscaler API in the Autoscaling
API group): The Horizontal Pod Autoscaling feature now supports custom metrics
(Alpha), allowing you to specify application-level metrics and thresholds to
trigger scaling up and down the number of pods in your application.

### SIG-autoscaling

SIG Autoscaling focused on improving the Horizontal Pod Autoscaling API and algorithm:
- We released autoscaling/v2beta2, which cleans up and unifies the API
- We improved readiness detection and smoothing to work well in a larger variety or use cases

### SIG-Azure

 *  Fix: Gracefully recover from HTTP/2 connection shutdowns at start of request.
 *  Fix: Be lenient if a `MediaType`'s character set is `'single-quoted'`.
 *  Fix: Allow horizontal tab characters in header values.
 *  Fix: When parsing HTTP authentication headers permit challenge parameters in any order.


## Version 3.4.2

_2016-11-03_

*   HPA tolerance is now configurable by setting the `horizontal-pod-autoscaler-tolerance` flag. ([#52275](https://github.com/kubernetes/kubernetes/pull/52275),[ @mattjmcnaughton](https://github.com/mattjmcnaughton))

### 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.
