- Kube-scheduler now falls back to emitting events using core/v1 Events when events.k8s.io/v1beta1 is disabled. ([#83692](https://github.com/kubernetes/kubernetes/pull/83692), [@yastij](https://github.com/yastij))

* `500` and above are for server errors. You almost never use them directly. When something goes wrong at some part in your application code, or server, it will automatically return one of these status codes.

Das wird:

* Diesen Statuscode mit der Response zurücksenden.
* Ihn als solchen im OpenAPI-Schema dokumentieren (und somit in den Benutzeroberflächen):

/// note | "Hinweis"

Einige Responsecodes (siehe nächster Abschnitt) kennzeichnen, dass die Response keinen Body hat.

Это позволит:

* Возвращать указанный код статуса в ответе.
* Документировать его как код статуса ответа в OpenAPI схеме (а значит, и в пользовательском интерфейсе):

<img src="/img/tutorial/response-status-code/image01.png">

/// note | "Примечание"

Некоторые коды статуса ответа (см. следующий раздел) указывают на то, что ответ не имеет тела.

    assertSame(key, notification.getKey());
    assertSame(value, notification.getValue());
    assertSame(cause, notification.getCause());
  }

  // Segment core tests

  public void testNewEntry() {
    for (CacheBuilder<Object, Object> builder : allEntryTypeMakers()) {
      LocalCache<Object, Object> map = makeLocalCache(builder);

      Object keyOne = new Object();

    assertSame(key, notification.getKey());
    assertSame(value, notification.getValue());
    assertSame(cause, notification.getCause());
  }

  // Segment core tests

  public void testNewEntry() {

      Object keyOne = new Object();

You probably read before that you can set a default [Response Status Code](../tutorial/response-status-code.md){.internal-link target=_blank}.

But in some cases you need to return a different status code than the default.

## Use case

For example, imagine that you want to return an HTTP status code of "OK" `200` by default.

But if the data didn't exist, you want to create it, and return an HTTP status code of "CREATED" `201`.
