 *  Fix: Make logging more consistent throughout OkHttp.
 *  Fix: Log plaintext bodies only. This uses simple heuristics to differentiate
    text from other data.
 *  Fix: Recover from `REFUSED_STREAM` errors in HTTP/2. This should improve
    interoperability with Nginx 1.10.0, which [refuses][nginx_959] streams
    created before HTTP/2 settings have been acknowledged.
 *  Fix: Improve recovery from failed routes.
