    a source-incompatible change, and is different from OkHttp 2.0.0-RC2 which
    used `Throwable`.
 *  Fix: Fixed a caching bug where we weren't storing rewritten request headers
    like `Accept-Encoding`.
 *  Fix: Fixed bugs in handling the SPDY window size. This was stalling certain
    large downloads
 *  Update the language level to Java 7. (OkHttp requires Android 2.3+ or Java 7+.)
