    update also drops support for the `DurationUnit` functions introduced in earlier alpha releases
    of OkHttp 5.

OkHttp 4’s minimum requirements are Java 8+ and Android 5+. These requirements were
[first introduced][require_android_5] with OkHttp 3.13.

Here’s what you need in `build.gradle` to target Java 8 byte code for Kotlin, Java, and Android
plugins respectively.

```groovy
compileKotlin {
  kotlinOptions {
