In your @FastAPI apps, are you using @pydantic version 1 or 2?
If v1, why haven't you upgraded to v2? 🤔
I wanna make sure everyone upgraded or can upgrade so that I can remove support for v1.

So glad you are an opensource guy and not a big tech company, else you would just cut off V1 forcing all users to use V2 and make it a paid service. But please, this is not a blueprint, ok?
