[eyurtsev]

• Need to make kor pydantic v1 and v2 compatible

[codenamics]

how is it going?

[erichlin1]

@eyurtsev when do you anticipate support for pydantic v2?

[erichlin1]

@eyurtsev Thank you!

[eyurtsev]

@ericlinsd np -- not ready yet, but almost there will probably release by end of week

[eyurtsev]

Merged on main. CI tests pass with both pydantic v1 and pydantic v2 so the library is now compatible with both versions of pydantic.

#223

[eyurtsev]

Release on pypi under version 1.0.0 -- has good unit test coverage, but let me know if there are any unexpected issues

There's an outstanding warning about config extra, otherwise 1.0.0 works like a charm with 2.3.0 for all I see! thank you!
