# [2.0.0](https://github.com/thi-ng/umbrella/compare/@thi.ng/paths@1.6.6...@thi.ng/paths@2.0.0) (2019-01-21)
### Build System
* update package build scripts & outputs, imports in ~50 packages ([b54b703](https://github.com/thi-ng/umbrella/commit/b54b703))
### BREAKING CHANGES
* enabled multi-outputs (ES6 modules, CJS, UMD)
- build scripts now first build ES6 modules in package root, then call
`scripts/bundle-module` to build minified CJS & UMD bundles in `/lib`
- all imports MUST be updated to only refer to package level
(not individual files anymore). tree shaking in user land will get rid of
all unused imported symbols.
