 * New: Support for `spdy/3.1`. Dropped support for `spdy/3`.
 * New: Use ALPN on Android platforms that support it (4.4+)
 * New: CacheControl model and parser.
 * New: Protocol selection in MockWebServer.
 * Fix: Route selection shouldn't use TLS modes that we know will fail.
 * Fix: Cache SPDY responses even if the response body is closed prematurely.
 * Fix: Use strict timeouts when aborting a download.
