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.

I do have some suggestions for making it better though...

For recipe:

• Old-style Python selectors (py27, py34, py35, py36) are deprecated. Instead, consider using the int py. For example: # [py>=36]. See lines [14]
