## Version 3.9.0

_2017-09-03_

 *  **Interceptors are more capable.** The `Chain` interface now offers access
    to the call and can adjust all call timeouts. Note that this change is
    source-incompatible for code that implements the `Chain` interface.
    We don't expect this to be a problem in practice!

 *  **OkHttp has an experimental new API for tracking metrics.** The new

#### 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).
  Two annotations have been promoted to API fields:

        final Map<String, String> params = new HashMap<String, String>();
