## What’s New (Major Themes)

### Deprecation warnings

SIG API Machinery implemented [warnings when using deprecated APIs](https://kubernetes.io/docs/reference/using-api/deprecation-policy/#rest-resources-aka-api-objects)
that are visible to `kubectl` users and API consumers, and metrics visible to cluster administrators.

因此，如果你未提供，**FastAPI** 會自動產生 "Successful response"。

## 將「路徑操作」標記為已棄用 { #deprecate-a-path-operation }

若需要將「路徑操作」標記為 <dfn title="已過時，建議不要再使用">已棄用</dfn>，但不移除它，請傳入參數 `deprecated`：

{* ../../docs_src/path_operation_configuration/tutorial006_py310.py hl[16] *}

在互動式文件中，它會被清楚標示為已棄用：

 * <strong>Warning:</strong> This is an internal utility class that is only public for technical reasons, it is not part
 * of the public API. In particular, this class can be changed or deleted without prior notice.

@Deprecated
public final class MetadataBridge extends AbstractMetadata implements MergeableMetadata {

    private ArtifactMetadata metadata;

    private boolean merged;

    public MetadataBridge(ArtifactMetadata metadata) {

   *     deprecated {@code Throwables.propagate}</a>.
   */
  @CanIgnoreReturnValue
  @J2ktIncompatible
  @GwtIncompatible
  @Deprecated
  public static RuntimeException propagate(Throwable throwable) {
    throwIfUnchecked(throwable);
    throw new RuntimeException(throwable);
  }

  /**
   * Returns the innermost cause of {@code throwable}. The first throwable in a chain provides

            <multiplicity>*</multiplicity>
          </association>
        </field>
        <field>
          <version>1.0.0</version>
          <name>deprecation</name>
          <description>A preferred alternative to this expression, in the case where it's deprecated.</description>
          <type>String</type>
        </field>
        <field>
          <version>1.0.0</version>
          <name>ban</name>

そのため、それを提供しない場合は、**FastAPI** が自動的に「成功のレスポンス」を生成します。

## *path operation*を非推奨にする { #deprecate-a-path-operation }

*path operation*を<dfn title="非推奨、使用しないことを推奨">deprecated</dfn>としてマークする必要があるが、それを削除しない場合は、`deprecated`パラメータを渡します:

{* ../../docs_src/path_operation_configuration/tutorial006_py310.py hl[16] *}

対話的ドキュメントでは非推奨と明記されます:
