 *  **OkHttp now supports TLS 1.3.** This requires either Conscrypt or Java 11+.

 *  **Proxy authenticators are now asked for preemptive authentication.** OkHttp will now request
    authentication credentials before creating TLS tunnels through HTTP proxies (HTTP `CONNECT`).
    Authenticators should identify preemptive authentications by the presence of a challenge whose
    scheme is "OkHttp-Preemptive".
