I am using this gem with Jekyll 3 with some modifications. I have making a new compatible release on my plan, but no time table.

Motivation and pull requests welcome 😄

I have tentatively put making a new release on my plan for next week.

@donv this fork worked fine for me https://github.com/kesha-antonov/jekyll-slim

[brauliobo]

Applied a fix for layouts support, https://github.com/olery/jekyll-slim. I might help maintaining if you need :)
