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) and found it was in an excellent condition.

The issue causing the builds to fail has been fixed in https://github.com/rdkit/rdkit/pull/4885 which should be released in 2021.09.5

Perfect. We'll keep this open so the bot knows we are not py310 compliant yet. When the new version lands, this will be automatically resubmitted.
