    `Headers` class offers full access to the HTTP headers.

 *  **Okio dependency added.** OkHttp now depends on
    [Okio](https://github.com/square/okio), an I/O library that makes it easier
    to access, store and process data. Using this library internally makes OkHttp

    immediate exception.
 *  New: Headers can be redacted in `HttpLoggingInterceptor`.
 *  New: `Headers.Builder` now accepts dates.
 *  New: OkHttp now accepts `java.time.Duration` for timeouts on Java 8+ and Android 26+.
 *  New: `Challenge` includes all authentication parameters.
