 *  New: `HandshakeCertificates.Builder.addInsecureHost()` makes it easy to turn off security in
    private development environments that only carry test data. Prefer this over creating an
    all-trusting `TrustManager` because only hosts on the allowlist are insecure. From
    [our DevServer sample][dev_server]:

    ```kotlin
    val clientCertificates = HandshakeCertificates.Builder()
        .addPlatformTrustedCertificates()

 * your server's TLS administrator!

 * ### Note about self-signed certificates
 *
 * [CertificatePinner] can not be used to pin self-signed certificate if such certificate is not
 * accepted by [javax.net.ssl.TrustManager].

 *  New: Accept user-provided trust managers in `OkHttpClient.Builder`. This
    allows OkHttp to satisfy its TLS requirements directly. Otherwise OkHttp
    will use reflection to extract the `TrustManager` from the
    `SSLSocketFactory`.
 *  New: Support prerelease Java 9. This gets ALPN from the platform rather than
    relying on the alpn-boot bootclasspath override.
