Checklist

• Used a personal fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

Notes:

• py39 will likely fail due to pendulum 1.4.4 (maybe some other things)
  • Historical 1.4.4 build for py39? pendulum-feedstock#27 (maintainers already very responsive)

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.

pendulum for py39 should be available within the hour ... though other stuff might be missing...
