    check if the call was canceled from within the callback. When migrating
    async calls to this new API, `Call` is now the first parameter for both
    `onResponse()` and `onFailure()`.
 *  Fix: handle multiple cookies in `JavaNetCookieJar` on Android.
 *  Fix: improve the default HTTP message in MockWebServer responses.
 *  Fix: don't leak file handles when a conditional GET throws.
