    and `Call`. With this release we’ve rearranged things so that the
    `HttpURLConnection` frontend now delegates to the `Call` APIs internally.
    This has enabled substantial simplifications and optimizations in the OkHttp
    core for both frontends.

    For most HTTP requests the consequences of this change will be negligible.
    If your application uses `HttpURLConnection.connect()`,
