 *  Fix: Don't crash in `HeldCertificate.Builder` when creating certificates on older versions of
    Android, including Android 6. We were using a feature of `SimpleDateFormat` that wasn't
    available in those versions!


## Version 4.8.0

 *  New: Change `HeldCertificate.Builder` to use its own ASN.1 certificate encoder. This is part

    if (!newRouteSelector.hasNext()) throw IOException("exhausted all routes")
    val newRouteSelection = newRouteSelector.next()

 *  New: Drop the `tunnelProxy` argument in `MockWebServer.useHttps()`. This change only impacts
    the OkHttp 5.x API which uses the `mockwebserver3` package.
 *  Fix: Don't call `toDuration()` which isn't available in kotlin-stdlib 1.4.


## Version 5.0.0-alpha.8

 *  Fix: Change how `H2_PRIOR_KNOWLEDGE` works with HTTP proxies. Previously OkHttp assumed the
