#### Implementation changes

 * Support Android `TrafficStats` socket tagging.
 * Drop authentication headers on redirect.
 * Added support for compressed data frames.

 *  New in okhttp-android: `HttpLoggingInterceptor.androidLogging()` and
    `LoggingEventListener.androidLogging()` write HTTP calls or events to Logcat.

 *  New: `OkHttpClient.webSocketCloseTimeout` configures how long a web socket connection will wait
    for a graceful shutdown before it performs an abrupt shutdown.
