useful for splitting out canceled calls in metrics.

 *  New: Publish a [bill of materials (BOM)][bom] for OkHttp. Depend on this from Gradle or Maven to
    keep all of your OkHttp artifacts on the same version, even if they're declared via transitive
    dependencies. You can even omit versions when declaring other OkHttp dependencies.

    ```kotlin

    // ResponseFailed, ConnectionReleased, CallFailed
    // JDK 8
    // CallStart, ProxySelectStart, ProxySelectEnd, DnsStart, DnsEnd, ConnectStart, SecureConnectStart,
    // ConnectFailed, CallFailed
    // Gradle - JDK 11
    // CallStart, ProxySelectStart, ProxySelectEnd, DnsStart, DnsEnd, ConnectStart, SecureConnectStart,
    // SecureConnectEnd, ConnectFailed, CallFailed
    val recordedEventTypes = listener.recordedEventTypes()

GraalVM is an exciting new platform and we're eager to adopt it. The startup time improvements over
the JVM are particularly impressive. Try it with okcurl:

```
$ ./gradlew okcurl:nativeImage
$ ./okcurl/build/graal/okcurl https://cash.app/robots.txt
```

This is our first release that supports GraalVM. Our code on this platform is less mature than JVM

 * **Binary compatibility** is the ability to compile a program against OkHttp 3.x, and then to run
   it against OkHttp 4.x. We’re using the excellent [japicmp][japicmp] library via its
   [Gradle plugin][japicmp_gradle] to enforce binary compatibility.

 * **Java source compatibility** is the ability to upgrade Java uses of OkHttp 3.x to 4.x without
   changing `.java` files.
