    faster while consuming less memory. You can write a `RequestBody` as an Okio
    `BufferedSink` and a `ResponseBody` as an Okio `BufferedSource`. Standard
    `InputStream` and `OutputStream` access is also available.

 *  **New Call and Callback types** execute requests and receive their
    responses. Both types of calls can be canceled via the `Call` or the
    `OkHttpClient`.
