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

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

Your run export is for the major version only.

can we just add a pin of "1" to the global pinning?

    - {{ pin_subpackage("ucc") }}

good catch, done

[hmaarrfk]

The earliest version of the package was 1.2.

so any 1.2 build should be compatibile even with 1.X.

so you can just directly add it to https://github.com/conda-forge/conda-forge-pinning-feedstock/blob/main/recipe/conda_build_config.yaml#L888

ucc:
   - 1

Sure, if touching conda_build_config.yaml directly is better. Done.

In these cases where you are being proactive, its just simpler and avoids rebuilds!
