 *  New: `Cache` now has a public constructor that takes an [okio.FileSystem]. This should make it
    possible to implement decorators for cache encryption or compression.
 *  New: `Cookie.newBuilder()` to build upon an existing cookie.
 *  New: Use TLSv1.3 when running on JDK 8u261 or newer.
 *  New: `QueueDispatcher.clear()` may be used to reset a MockWebServer instance.

    The best practice in OkHttp 3 is to create a single OkHttpClient instance
    and share it throughout the application. Requests that needs a customized
    client should call `OkHttpClient.newBuilder()` on that shared instance.
    This allows customization without the drawbacks of separate connection
    pools.

 *  **OkHttpClient is now stateless.** In the 2.x API `OkHttpClient` had getters
