*  Fix: Change the return type of `MockWebServer.takeRequest()` to be nullable.
 *  Fix: Make `Call.clone()` public to Kotlin callers.


## Version 4.0.0-RC1

_2019-06-03_

 *  First stable preview of OkHttp 4.


## Version 3.x

[Change log](https://square.github.io/okhttp/changelog_3x/)


 [bom]: https://docs.gradle.org/6.2/userguide/platforms.html#sub:bom_import

 *  New: `okhttp-dnsoverhttps` is an experimental API for doing DNS queries over HTTPS. Using HTTPS
    for DNS offers better security and potentially better performance. This feature is a preview:
    the API is subject to change.
 *  New: `okhttp-sse` is an early preview of Server-Sent Events (SSE). This feature is incomplete
    and is only suitable for experimental use.

    .fastFallback(true)
    .build();
```

 *  New: Change the build from Kotlin-JVM to Kotlin-multiplatform (which includes JVM). Both
    native and JavaScript platforms are unstable preview releases and subject to
    backwards-incompatible changes in forthcoming releases.
 *  Fix: Don't crash loading the public suffix database resource in obfuscated builds.
