Great job! 🎉

I just updated it to pin Pydantic to 0.30, as 0.31 is not released yet and could include breaking changes.

It's perfect to have these changes for each release, I prefer to have frequent independent releases with each dependency version when possible. In case a future version breaks something, users can still use the features and bug fixes in this version.

Thanks! 🎉 🚀 🍰
