 *  Fix: Drop partial support for HTTP/1.0. Previously OkHttp would send
    `HTTP/1.0` on connections after seeing a response with `HTTP/1.0`. The fixed
    behavior is consistent with Firefox and Chrome.
 *  Fix: Allow a body in `OPTIONS` requests.
 *  Fix: Don't percent-encode non-ASCII characters in URL fragments.
 *  Fix: Handle null fragments.

 *  Fix: Follow HTTP 307 and 308 redirects on methods other than GET and POST. We're reluctant to
    change OkHttp's behavior in handling common HTTP status codes, but this fix is overdue! The new
    behavior is now consistent with [RFC 7231][rfc_7231_647], which is newer than OkHttp itself.
    If you want this update with the old behavior use [this interceptor][legacy_interceptor].

 *  New: Don't include the `Content-Length` header in multipart bodies. Servers must delimit
    OkHttp's request bodies using the boundary only. (This change makes OkHttp more consistent with
    browsers and other HTTP clients.)
 *  New: Drop the `tunnelProxy` argument in `MockWebServer.useHttps()`. This change only impacts
    the OkHttp 5.x API which uses the `mockwebserver3` package.
