 *  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.
