    configure OkHttp 3.13 to allow TLSv1 and TLSv1.1 connections:

    ```
    OkHttpClient client = new OkHttpClient.Builder()
        .connectionSpecs(Arrays.asList(ConnectionSpec.COMPATIBLE_TLS))
        .build();
    ```

 *  New: You can now access HTTP trailers with `Response.trailers()`. This method may only be called
    after the entire HTTP response body has been read.
