## Provider-specific Notes

* AWS
  * Support for ap-northeast-2 region (Seoul)
  * Allow cross-region image pulling with ECR
  * More reliable kube-up/kube-down
  * Enable ICMP Type 3 Code 4 for ELBs
  * ARP caching fix
  * Use /dev/xvdXX names
  * ELB:
    * ELB proxy protocol support 
	* mixed plaintext/encrypted ports support in ELBs
    * SSL support for ELB listeners
  * Allow VPC CIDR to be specified (experimental)
