 *  Fix: Improve connection timeout recovery.
 *  Fix: Recover from `getsockname` crashes impacting Android releases prior to
    4.2.2.
 *  Fix: Drop partial support for HTTP/1.0. Previously OkHttp would send
    `HTTP/1.0` on connections after seeing a response with `HTTP/1.0`. The fixed
    behavior is consistent with Firefox and Chrome.
 *  Fix: Allow a body in `OPTIONS` requests.
