BREAKING CHANGES

• 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').
• by default css modules are disabled (now modules: false disable all css modules features), you can return old behaviour change this on modules: 'global'
• css-loader/locals was dropped in favor exportOnlyLocals option
• import option only affect on import at-rules and doesn't affect on composes declarations
• invalid @import at rules now emit warnings
• use postcss@7

1.0.1 (2018-10-29)
