[jdoiro3]

Note

I know this project isn't maintained anymore and understand this probably will never merge.

Proposed changes

Bump Pydantic to >=2.0.0 since it ships with v1. All you have to do is change from pydantic to from pedantic.v1.

Types of changes

These changes should not have any impact on dbx and is more about letting users of dbx to migrate from pydantic v1 to v2.

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation Update (if none of the other choices apply)

Further comments

If this is a relatively large or complex change, kick off the discussion by explaining why you chose the solution you did and what alternatives you considered, etc...
