*  Fix: Handle 'Expect: 100 Continue' properly in MockWebServer.


## Version 3.8.1

_2017-06-18_

 *  Fix: Recover gracefully from stale coalesced connections. We had a bug where
    connection coalescing (introduced in OkHttp 3.7.0) and stale connection
    recovery could interact to cause a `NoSuchElementException` crash in the
    `RouteSelector`.


## Version 3.8.0

_2017-05-13_

 *  Fix: Avoid crashing when cache writing fails due to a full disk.
 *  Fix: Improve caching of private responses.
 *  Fix: Update cache-by-default response codes.
 *  Fix: Reused `Request.Builder` instances no longer hold stale URL fields.
 *  New: ConnectionSpec can now be configured to use the SSL socket's default
    cipher suites. To use, set the cipher suites to `null`.
 *  New: Support `DELETE` with a request body.

everywhere. Otherwise the two cache instances will stomp on each other, corrupt the response cache, and possibly crash your program.

Response caching uses HTTP headers for all configuration. You can add request headers like `Cache-Control: max-stale=3600` and OkHttp's cache will honor them. Your webserver configures how long responses are cached with its own response headers, like `Cache-Control: max-age=9600`. There are cache headers to force a cached response, force a network response, or force...

- Whenever a pod was successfully bound to a node, the kube-apiserver  cleared the pod's `nominatedNodeName` field. This prevented stale information from affecting external scheduling components.
