    import this and we want to ease upgrades for their users.


## Version 4.0.0-RC2

_2019-06-21_

 *  New: Require Kotlin 1.3.40.
 *  New: Change the Kotlin API from `File.toRequestBody()` to `File.asRequestBody()` and
    `BufferedSource.toResponseBody()` to `BufferedSource.asResponseBody()`. If the returned value
    is a view of what created it, we use _as_.

 *  New: Use TLSv1.3 when running on JDK 8u261 or newer.
 *  New: `QueueDispatcher.clear()` may be used to reset a MockWebServer instance.
 *  New: `FileDescriptor.toRequestBody()` may be particularly useful for users of Android's Storage
    Access Framework.
 *  Upgrade: [Kotlin 1.5.31][kotlin_1_5_31].
 *  Upgrade: [Okio 3.0.0][okio_3_0_0].


## Version 5.0.0-alpha.2
