Plans for Pydantic v2?

[sleiner]

Since the pydantic 2.0 will likely release very soon and will contain quite a few breaking changes, I am wondering what this project's plans are for adopting it.

As an aside: I am not complaining, just checking :-) Thanks for all your work on pydantic-xml!

I'm also very excited for Pydantic 2.0 and I'm willing to help if needed!

I am working on it. pydantic 2.0 has a lot of breaking changes so it could take some time to adopt the library for the new api. I suppose alpha version will be available within a month.

alpha release is available for testing https://pypi.org/project/pydantic-xml/2.0.0a1/

I tried to keep the api where it possible.

Breaking changes:

• custom root type declaration has been changed. It must inherit RootXmlModel from now on. See for more details.
• generic models are no longer inherited from BaseGenericXmlModel but from BaseXmlModel. See.
• encoding customization api has been changed. See.

New features:

• element attributes can be bound to TypedDict
• similar to pydantic computed fields it is possible to declare computed entities.
