Autoprefixer 8.0 uses Browserslist 3.0, has autoprefixer CLI tool instead of autoprefixer-info.

Browserslist 3.0

The main feature of Autoprefixer 8.0 is Browserslist 3.0. In the new version, it brings new default browsers. It will affect you only if you don’t change browsers by .browserslistrc or browserslist key in package.json (we don’t recommend to use browsers option).

In one hand, Browserslist 3.0 usage statistics limit for default browsers was reduced from >1% to >0.5%. In another hand, we remove dead browsers from default browsers. The dead browser is a browser with < than 1% in the global market and who don’t have security updates. Right now IE 10 and BlackBerry browser are dead browsers.

CLI Tool

CLI tool to show target browsers and used prefixes was renamed to autoprefixer:

$ npx autoprefixer --info
Browsers:
  Edge: 16

These browsers account for 0.04% of all users globally

At-Rules:
  @viewport: ms

Selectors:
  ::placeholder: ms

Properties:
  user-select: ms
  hyphens: ms
  appearance: webkit
  scroll-snap-type: ms
  scroll-snap-coordinate: ms

  scroll-snap-points-x: ms
  scroll-snap-points-y: ms
  flow-into: ms
  flow-from: ms
  region-fragment: ms
  text-spacing: ms

With the new name, npx will install Autoprefixer automatically if it is missed in the current project.

Page Breaks for Firefox

Previous Autoprefixer versions replace break-* properties to page-break-* for Firefox.

But this feature didn’t add any vendor prefix. Autoprefixer goal is to take care only about prefixes, not polyfills. For better consistency, we removed this feature from Autoprefixer.

Don’t afraid, the PostCSS ecosystem has many plugins for CSS polyfills. We recommend to take look at postcss-preset-env to write future CSS today.
