2.0 and workflow : .ciignore?


Hi, I read this blog subject : CircleCI Hacks - Automate the Decision to Skip Builds Using a Git Hook

So I try this with my circleci 2.0 project and .ciignore isn’t used.

Do I make a mistake or the feature isn’t available for the 2.0 ?

Can I propose a new feature or their is an existing workaround for this ?
