* `metrics-server` is now the recommended way to provide the resource
  metrics API. Deploy `metrics-server` as an add-on in the same way that you deploy Heapster.

##### Cluster Autoscaler

* Cluster autoscaler is now GA
* Cluster support size is increased to 1000 nodes

## What’s New (Major Themes)

### Cloud Provider Labels reach General Availability

Added as a beta feature way back in v1.2, v1.17 sees the general availability of cloud provider labels.

### Volume Snapshot Moves to Beta

   * An iterator that performs a lazy N-way merge, calculating the next value each time the iterator
   * is polled. This amortizes the sorting cost over the iteration and requires less memory than
   * sorting all elements at once.
