## 非推奨パラメータ

さて、このパラメータが気に入らなくなったとしましょう

それを使っているクライアントがいるので、しばらくは残しておく必要がありますが、ドキュメントには<abbr title="使わない方がよい">非推奨</abbr>と明記しておきたいです。

その場合、`Query`にパラメータ`deprecated=True`を渡します:

```Python hl_lines="18"
{!../../docs_src/query_params_str_validations/tutorial010.py!}
```

ドキュメントは以下のようになります:

OkHttp 1.x Change Log
=====================

## Version 1.6.0

   dropped in 2.0.

## Version 1.5.4
