You will also need to configure this dependency:

```
dependencies {
  implementation "org.bouncycastle:bcprov-jdk15on:1.65"
}
```

 *  Upgrade: [Kotlin 1.4.10][kotlin_1_4_10]. We now use Kotlin 1.4.x [functional
    interfaces][fun_interface] for `Authenticator`, `Interceptor`, and others.
 *  Upgrade: Build with Conscrypt 2.5.1.
