R8 / ProGuard
-------------

R8 and ProGuard are both code optimizers for `.class` files.

R8 is the [default optimizer][r8] in Android Studio 3.4 and newer. It works well with all
releases of OkHttp.

 *  Fix: Use literal IP addresses directly rather than passing them to `DnsOverHttps`.
 *  Fix: Embed Proguard rules to prevent warnings from tools like DexGuard and R8. These warnings
    were triggered by OkHttp’s feature detection for TLS packages like `org.conscrypt`,
    `org.bouncycastle`, and `org.openjsse`.
