*  Fix: Don't share the OkHttpClient's `Dispatcher` in `HttpURLConnection`.


## Version 3.4.0-RC1

_2016-07-02_

 *  **We’ve rewritten HttpURLConnection and HttpsURLConnection.** Previously we
    shared a single HTTP engine between two frontend APIs: `HttpURLConnection`
    and `Call`. With this release we’ve rearranged things so that the
    `HttpURLConnection` frontend now delegates to the `Call` APIs internally.
