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/recipe.yaml) and found it was in an excellent condition.

A reasonable improvement in build speed (though x86_64 linux didn't move), just wanted to see.
If you'd like to merge, please do so, if not I am fine with that.

I don't have much of a say here, but looks good to me :)

Let me redo this one since it's been 8 months.
