 *  New: `Challenge` includes all authentication parameters.
 *  New: Upgrade to BouncyCastle 1.60, Conscrypt 1.4.0, and Okio 1.15.0. We don't yet require
    Kotlin-friendly Okio 2.x but OkHttp works fine with that series.

 * ### Host
 *
 * The host identifies the webserver that serves the URL's resource. It is either a hostname like
 * `square.com` or `localhost`, an IPv4 address like `192.168.0.1`, or an IPv6 address like `::1`.
 *

     * ensure that completed write operations performed by other threads are noticed. For most
     * purposes, the "count" field, tracking the number of elements, serves as that volatile
     * variable ensuring visibility. This is convenient because this field needs to be read in many
     * read operations anyway:
