Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found some lint.

Here's what I've got...

For recipe/meta.yaml:

• ❌ The MACOSX_DEPLOYMENT_TARGET key in /tmp/tmp1fmc8f7z/cf_feedstock_ops_dir/recipe/conda_build_config.yaml needs to be removed or replaced by c_stdlib_version, appropriately restricted to osx

For recipe/meta.yaml:

• ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.

I am a bit confused by the error here as fastframes-feedstock is not using recipe/conda_build_config.yaml for anything. From what I can see here it seems like things should be handled correctly?

Edit: I guess this is probably just from the recipe/conda_build_config.yaml from conda-forge-pinning-feedstock itself.
