postcss/postcss-cli v3.0.0-beta

on GitHub

Breaking Changes

• Uses https://github.com/michael-ciniawsky/postcss-load-config for config files. Dropped support for the v2 config file format.
• Can't set input files in config file; pass input files on the command line instead.
• --use accepts a list of plugins. This may cause issues if you have your list of css files at the end of your command.
• Can't pass options to plugins via --plugin.key=value anymore, use a config file.
• Changed usage of the --map option; use --map for external sourcemaps, --no-map to disable all maps. Inline sourcemaps are default.
• Removed --log flag; this behavior is now default.
• Removed the --local-plugins flag; same result can be achieved with postcss.config.js.
• Removed the global watchCSS handler, plugins that import/rely on other files should use a dependency message instead.

New Features

• --ext (-x) option allows you to set the file extensions for your output files when using --dir.
• --env allows you to set NODE_ENV in a cross-platform manner.

Please test this beta release and report any bugs you find.
