* Flex volume plugin is updated to support attach/detach interfaces. It broke backward compatibility. Please update your drivers and implement the new callouts.  ([#41804](https://github.com/kubernetes/kubernetes/pull/41804), [@chakri-nelluri](https://github.com/chakri-nelluri))

This last path operation will have the combination of tags: `["items", "custom"]`.

And it will also have both responses in the documentation, one for `404` and one for `403`.

///

## The main `FastAPI` { #the-main-fastapi }

Now, let's see the module at `app/main.py`.

Here's where you import and use the class `FastAPI`.

)
router2_default = APIRouter()
router4_override = APIRouter(
    prefix="/level4",
    tags=["level4a", "level4b"],
    dependencies=[Depends(dep4)],
    responses={
        404: {"description": "Client error level 4"},
        504: {"description": "Server error level 4"},
    },
    default_response_class=ResponseLevel4,
    callbacks=callback_router4.routes,
    deprecated=True,
)
router4_default = APIRouter()

{* ../../docs_src/bigger_applications/app_an_py310/routers/items.py hl[30:31] title["app/routers/items.py"] *}

/// tip | 提示

這最後一個路徑操作會有組合後的標籤：`["items", "custom"]`。

而且在文件中同時會有 `404` 與 `403` 兩種回應。

///

## 主程式 `FastAPI` { #the-main-fastapi }

現在，來看看 `app/main.py` 這個模組。

你會在這裡匯入並使用 `FastAPI` 類別。

這會是你的應用程式中把一切串起來的主檔案。

而隨著大多數的邏輯都放在各自的模組中，主檔案會相當簡潔。

 *  New: Support OSGi metadata.
 *  Upgrade: [Okio 2.9.0][okio_2_9_0].

    ```kotlin
    implementation("com.squareup.okio:okio:2.9.0")
    ```

Note that this was originally released on 2020-10-06 as 4.10.0-RC1. The only change from that
release is the version name.

## Version 4.x

See [4.x Change log](https://square.github.io/okhttp/changelogs/changelog_4x/) for the legacy version changelogs.

- Changed kuberc configuration schema. Two new optional fields added to kuberc configuration, `credPluginPolicy` and `credPluginAllowlist`. This is documented in [KEP-3104](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cli/3104-introduce-kuberc/README.md#allowlist-design-details) and documentation is added to the website by [kubernetes/website#52877](https://github.com/kubernetes/website/pull/52877) ([#134870](https://github.com/kuber...
