Backwards compatibility tests exist to test upgrading from each supported version
to the current version. To run them all use:

-------------------------------------------------
./gradlew bwcTest
-------------------------------------------------

A specific version can be tested as well. For example, to test bwc with
version 5.3.2 run:

-------------------------------------------------
./gradlew v5.3.2#bwcTest

create Deployment Beta resources after upgrading to 1.2. Not deleting the
Deployment objects may cause the deployment controller to mistakenly match
other pods and delete them, due to the selector API change.
     * Client (kubectl) and server versions must match (both 1.1 or both 1.2) for any

## 基于标准的好处，备选文档 { #standards-based-benefits-alternative-documentation }

**FastAPI** 使用 [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md) 生成概图，所以能兼容很多工具。

因此，**FastAPI** 还内置了 ReDoc 生成的备选 API 文档，可在此查看 [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc)：

<img src="/img/tutorial/path-params/image02.png">

同样，还有很多兼容工具，包括多种语言的代码生成工具。

/// info | 情報

FastAPI はバージョン 0.95.0 で`Annotated`のサポートを追加し（そして推奨し始めました）。

古いバージョンの場合、`Annotated`を使おうとするとエラーになります。

`Annotated`を使用する前に、FastAPI のバージョンを少なくとも 0.95.1 まで[アップグレードしてください](../deployment/versions.md#upgrading-the-fastapi-versions)。

## メタデータの宣言 { #declare-metadata }

パラメータは`Query`と同じものを宣言することができます。

例えば、パスパラメータ`item_id`に対して`title`のメタデータを宣言するには以下のようにします:

          }

          line[0] == ':' -> {
            // Work around empty header names and header names that start with a colon (created by old
            // broken SPDY versions of the response cache).
            addLenient("", line.substring(1)) // Empty header name.
          }

          else -> {
            // No header name.
            addLenient("", line)
          }
