 *  **Forbid response bodies on HTTP 204 and 205 responses.** Webservers that
    return such malformed responses will now trigger a `ProtocolException` in
    the client.

 *  **WebSocketListener has incompatible changes.** The `onOpen()` method is now
    called on the reader thread, so implementations must return before further
