Release Notes

### [`v7.0.0`](https://github.com/webpack-contrib/sass-loader/blob/master/CHANGELOG.md#​700httpsgithubcomwebpack-contribsass-loadercomparev607v700-2018-04-13) ##### Features * Refactor resolving and simplify webpack config aliases (#​479) ([e0fde1a](https://github.com/webpack-contrib/sass-loader/commit/e0fde1a)) * Remove `node-sass` from `peerDependencies` (#​533) ([6439cef](https://github.com/webpack-contrib/sass-loader/commit/6439cef)) ##### BREAKING CHANGES * Drop official node 4 support * This slightly changes the resolving algorithm. Should not break in normal usage, but might break in complex configurations. * The sass-loader throws an error at runtime now and refuses to compile if the peer dependency is wrong. This could break applications where npm's peer dependency warning was just ignored. #### [6.0.7](https://github.com/webpack-contrib/sass-loader/compare/v6.0.6...v6.0.7) (2018-03-03) ##### Bug Fixes * **package:** add `webpack >= v4.0.0` (`peerDependencies`) ([#​541](`https://github.com/webpack-contrib/sass-loader/issues/541`)) ([620bdd4](https://github.com/webpack-contrib/sass-loader/commit/620bdd4)) ##### Performance Improvements * use `neo-async` instead `async` ([#​538](`https://github.com/webpack-contrib/sass-loader/issues/538`)) ([fab89dc](https://github.com/webpack-contrib/sass-loader/commit/fab89dc)) #### [6.0.6](https://github.com/webpack-contrib/sass-loader/compare/v6.0.5...v6.0.6) (2017-06-14) ##### Chore * Adds Webpack 3.x version range to peerDependencies --- ### [`v7.0.1`](https://github.com/webpack-contrib/sass-loader/blob/master/CHANGELOG.md#​701httpsgithubcomwebpack-contribsass-loadercomparev700v701-2018-04-13) ##### Bug Fixes * Wrong import precedence (#​557) ([f4eeff1](https://github.com/webpack-contrib/sass-loader/commit/f4eeff1)) ---
