What happened?

I have conda-lock installed via brew (it uses pydantic 2 for the build) and when I enter conda-lock render --help, I get the following warnings:

Thanks for the report!

These warning should be just warnings.

We have a fix in #459 for the next release.

Are you able to ignore the warnings? If you discover any malfunctions as a result, then please let us know!
