I would expect `typing_extensions.Doc` to be deprecated and then removed at some point from `typing_extensions`, for that reason there's the new `annotated-doc` micro-package. If you are curious about this, you can read more in the repo for [`annotated-doc`](https://github.com/fastapi/annotated-doc).

This new version `0.120.0` only contains that transition to the new home package for that utility class `Doc`.

### Preferred translations / glossary

1. Should avoid using simplified Chinese characters and terms. Always examine if the translation can be easily comprehended by the Traditional Chinese readers.
2. For some Python-specific terms like "pickle", "list", "dict" etc, we don't have to translate them.
3. Use the following preferred translations when they apply in documentation prose:

- request (HTTP): 請求
- response (HTTP): 回應
