I ran my grunt command just fine, then saw that grunt-sass 4.0.0 was available, so I updated. Now, every time I run grunt I get a fatal error:

Running "sass:dist" (sass) task
Fatal error: options.implementationpileAsync is not a function

If I downgrade back to 3.1.0 the error is gone and it works fine. No other changes were made to my configs.

Is there something I can do to fix this? I've searched my codebase for the compileAsync mentions and get zero results. (All my other plugins are up-to-date)
