instead of notifying the thread's uncaught exception handler. We've added a
    new API, `Call.isCanceled()` to check if a call has been canceled.

 *  New: Update `MultipartBuilder` to support content length.
 *  New: Make it possible to mock `OkHttpClient` and `Call`.
 *  New: Update to h2-14 and hpack-9.
 *  New: OkHttp includes a user-agent by default, like `okhttp/2.1.0-RC1`.
 *  Fix: Handle response code `308 Permanent Redirect`.

### Überschreiben des `HTTPException`-Fehlerhandlers { #override-the-httpexception-error-handler }

Auf die gleiche Weise können Sie den `HTTPException`-Handler überschreiben.

Zum Beispiel könnten Sie eine Klartext-Response statt JSON für diese Fehler zurückgeben wollen:

Bu durumda `startup` event handler fonksiyonu, "database" öğesini (sadece bir `dict`) bazı değerlerle başlatır.

Birden fazla event handler fonksiyonu ekleyebilirsiniz.

Ve tüm `startup` event handler’ları tamamlanmadan uygulamanız request almaya başlamaz.
