### Parallel Burgers

Now let's imagine these aren't "Concurrent Burgers", but "Parallel Burgers".

You go with your crush to get parallel fast food.

    Do not use these experimental APIs in modules that may be executed using a version of OkHttp
    different from the version that the module was compiled with. Do not use them in published
    libraries. Do not use them if you aren't willing to track changes to them.

 *  Breaking: Drop support for Kotlin Multiplatform.

    We planned to support multiplatform in OkHttp 5.0, but after building it, we weren't happy with

        // As recommended by the HTTP RFC and implemented in Firefox, the max age of a document
        // should be defaulted to 10% of the document's age at the time it was served. Default
        // expiration dates aren't used for URIs containing a query.
        val servedMillis = servedDate?.time ?: sentRequestMillis
        val delta = servedMillis - lastModified!!.time
        return if (delta > 0L) delta / 10 else 0L
      }

Vor Let's Encrypt wurden diese **HTTPS-Zertifikate** von vertrauenswürdigen Dritten verkauft.

Der Prozess zum Erwerb eines dieser Zertifikate war früher umständlich, erforderte viel Papierarbeit und die Zertifikate waren ziemlich teuer.

Aber dann wurde **<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>** geschaffen.

Wir möchten auch, dass FastAPI die Daten weiterhin, dem Responsemodell entsprechend, **filtert**.

Im vorherigen Beispiel mussten wir den `response_model`-Parameter verwenden, weil die Klassen unterschiedlich waren. Das bedeutet aber auch, wir bekommen keine Unterstützung vom Editor und anderen Tools, die den Funktions-Rückgabewert überprüfen.
