### Provider-specific Notes

#### Various

   Core changes:

  * Support for load balancers with source ranges

#### AWS

Core changes:

  * Support for ELBs with complex configurations: better subnet selection with
multiple subnets, and internal ELBs
  * Support for VPCs with private dns names

#### Load Balancing
* [stable] Source IP Preservation - change Cloud load-balancer strategy to health-checks and respond to health check only on nodes that host pods for the service. See [Create an External Load Balancer - Preserving the client source IP](https://kubernetes.io/docs/tasks/access-application-cluster/create-external-load-balancer/#preserving-the-client-source-ip).
