1.0.0

Warning: a number of breaking changes are included in this release

• Dropped the dir option, always use directory from position.source in the AST (see #10). You should provide the source option when parsing the CSS to get the right import directory.
• Search the alias option for aliased directories when importing (see #15)
• Never apply the alias config for relative imports (e.g. @import "./file";)
• Moved the repo to reworkcss/rework-npm
