### 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

   * when we use a newer -source and -target. That doesn't normally matter for AbstractFutureState,
   * since Android should normally succed in using UnsafeAtomicHelper and thus never even try the
   * problematic AtomicReferenceFieldUpdaterAtomicHelper code path. However, the same problem *does*
   * matter with AggregateFutureState, which does not have an Unsafe-based helper.

    interface to track metrics and monitor HTTP requests' size and duration.
 *  New: `okhttp-dnsoverhttps` is an experimental API for doing DNS queries over HTTPS. Using HTTPS
    for DNS offers better security and potentially better performance. This feature is a preview:
    the API is subject to change.
 *  New: `okhttp-sse` is an early preview of Server-Sent Events (SSE). This feature is incomplete
