 *  New: Make `ResponseBody.string()` and `ResponseBody.charStream()` BOM-aware. If your HTTP
    response body begins with a [byte order mark][bom] it will be consumed and used to select a
    charset for the remaining bytes. Most applications should not need a byte order mark.

 *  New: Upgrade to Okio 1.11.0.
