## Deprecating parameters { #deprecating-parameters }

Now let's say you don't like this parameter anymore.

You have to leave it there a while because there are clients using it, but you want the docs to clearly show it as <dfn title="obsolete, recommended not to use it">deprecated</dfn>.

Then pass the parameter `deprecated=True` to `Query`:

            """
        ),
    ] = None,
    deprecated: Annotated[
        deprecated | str | bool | None,
        Doc(
            """
            Mark this parameter field as deprecated.

            It will affect the generated OpenAPI (e.g. visible at `/docs`).
            """
        ),
    ] = None,

Code Cleanup
------------

IntelliJ and Android Studio offer a **Code Cleanup** feature that will automatically update
deprecated APIs with their replacements. Access this feature from the _Search Anywhere_ dialog
(double-press shift) or under the _Analyze_ menu.

We’ve included deprecated APIs in OkHttp 4.0 because they make migration easy. We will remove them

- EndpointSlice has a new NodeName field guarded by the EndpointSliceNodeName feature gate.
  - EndpointSlice topology field will be deprecated in an upcoming release.
  - EndpointSlice "IP" address type is formally removed after being deprecated in Kubernetes 1.17.

  - The deprecated `--etcd-quorum-read` flag has been removed. Quorum reads are now always enabled when fetching data from etcd. Remove the `--etcd-quorum-read` flag from kube-apiserver invocations before upgrading.
- kube-controller-manager
  - The deprecated `--insecure-experimental-approve-all-kubelet-csrs-for-group` flag has been removed.
- kubelet

如果没有定义响应描述，**FastAPI** 则自动生成内容为 "Successful response" 的响应描述。

## 弃用*路径操作* { #deprecate-a-path-operation }

如果需要把*路径操作*标记为<dfn title="过时，建议不要使用">弃用</dfn>，但不删除它，可以传入 `deprecated` 参数：

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

API 文档会把该路径操作标记为弃用：

    *   Deprecate `tf.data.Dataset.shard`.
    *   Deprecate `saved_model.loader.load` which is replaced by
        `saved_model.load` and `saved_model.main_op`, which will be replaced by
        `saved_model.main_op` in V2.
    *   Deprecate tf.QUANTIZED_DTYPES. The official new symbol is
        tf.dtypes.QUANTIZED_DTYPES.
    *   Update sklearn imports for deprecated packages.

## *경로 처리* 지원중단하기 { #deprecate-a-path-operation }

*경로 처리*를 제거하지 않고 <dfn title="구식이며 사용하지 않는 것이 권장됨">지원중단</dfn>으로 표시해야 한다면, `deprecated` 매개변수를 전달하면 됩니다:
