 *  **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".

* kube-apiserver now uses SSH tunnels for webhooks if the webhook is not directly routable from apiserver's network environment. ([#58644](https://github.com/kubernetes/kubernetes/pull/58644), [@yguo0905](https://github.com/yguo0905))
