### 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
  * Multiple fixes to EBS volume mounting code for robustness, and to support
