What happened?

It seems like conda build is not working on the OSX 15.1.1.
My conda build version is: 24.11.2
Another fact that might be important is that I'm using micromamba locally: 1.5.10
Though, I don't believe that would make a difference?

This is the error I get:

The new default `pkg_format` value will be '.conda'. If you want to keep using `.tar.bz2`, consider:
- Setting `conda_build.pkg_format: 'tar.bz2' in your condarc file.
- Using `--pkg-format=tar.bz2` in the CLI.

To remove this warning, please choose a default channel explicitly with conda's regular configuration system, e.g. by adding 'defaults' to the list of channels:

  conda config --add channels defaults
