## バージョンについて { #about-versions }

セマンティック バージョニングの規約に従って、`1.0.0` 未満のバージョンは破壊的な変更が加わる可能性があります。

FastAPI では「PATCH」バージョンの変更はバグ修正と非破壊的な変更に使う、という規約にも従っています。

/// tip | 豆知識

「PATCH」は最後の数字です。例えば、`0.2.3` では PATCH バージョンは `3` です。

///

従って、以下のようなバージョンの固定ができるはずです:

```txt
fastapi>=0.45.0,<0.46.0
```

破壊的な変更と新機能は「MINOR」バージョンで追加されます。

If you want to catch exceptions and create a custom response based on that, create a [Custom Exception Handler](../handling-errors.md#install-custom-exception-handlers).
