PostCSS 7.0 dropped Node.js 4 support and brought small features.
Breaking Changes
We removed Node.js 4 and Node.js 9 support since it doesn’t have security updates anymore.
We removed IE and “dead” browsers (without security updates) from Babel’s Browserslist. Don't worry, PostCSS still generate IE-compatible code. These changes affect websites which run PostCSS on client-side like CodePen.

@nikhilgaba added cute thing for plugin developers. If an error was happened in Container#walk() circle, PostCSS will show in stack trace CSS node, which causes this error:
TypeError: Cannot read property '0' of undefined

@igorkamyshev added finally method to LazyResult to make it compatible with the latest Promise API.
