 *  Fix: Release the connection if `Authenticator` throws an exception.
 *  Fix: Change the declaration of `OkHttpClient.cache()` to return a `@Nullable Cache`. The return
    value has always been nullable but it wasn't declared properly.
 *  Fix: Reverse suppression of connect exceptions. When both a call and its retry fail, we now
    throw the initial exception which is most likely to be actionable.

 * The Kotlin DSL now respects JSR-305 package annotations.

This will lead to some types annotated according to JSR-305 being treated as nullable where they were treated as non-nullable before.
This may lead to compilation errors in the build script. See https://github.com/gradle/kotlin-dsl/releases/tag/v0.17.4[the relevant Kotlin DSL release notes] for details.
