2.0.0 (2018-12-07)

The main BREAKING CHANGES:

css modules are disabled by default, you need setup their use modules option. You can setup their using local (true is alias for this value) and global (previous behaviour) value. Why it is disabled by default? A lot of developers use css without css modules features and they get performance problems due postcss plugins spend time on analyze and processing file.
resolving logic for uls() and import at-rules works the same everywhere, it does not matter whether css modules are enabled (with global and local module) or not. Examples - url('image.png') as require('./image.png'), url('./image.png') as require('./image.png'), url('~module/image.png') as require('module/image.png').
