    this was case sensitive. This change should also make it easier to configure
    certificate pinning for internationalized domain names.
 *  Fix: Don’t crash on non-ASCII `ETag` headers. Previously OkHttp would reject
    these headers when validating a cached response.
 *  Fix: Don’t allow remote peer to arbitrarily size the HPACK decoder dynamic
    table.
