Hi @MoOx!
I have updated the autoprefixer and added tests to test support for new features in PR #353

Hi, this is not useful (since semver handle this update automatically (we use a ^ with get minor and patch) and does not help us with browserlist here.

Thanks for making the dependency update and adding tests.

Updating "^6.0.2" to "^6.7.6" doesn't do anything because the ^ syntax in semver gets the latest version of the same major.

Not to mention, the CHANGELOG for autoprefixer says "Browserslist 2" was added in 7.0.

Would you update the autoprefixer entry in package.json to "^7.0.0" and reopen the PR?

Autoprefixer will be updated to 7.x in cssnext 3.x

Possibly resolved by #445
