The `functions` option can't be used as `Function`, you should use `sassOption` as `Function` to achieve this. - the `data` option was renamed to the `prependData` option - default value of the `sourceMap` option depends on the `devtool` value (`eval`/`false` values don't enable source map generation) ##### Features - automatically use the `fibers` package if it is possible ([#​744](https://togithub.com/webpack-contrib/sass-loader/issues/744)) ([96184e1](https://togithub.com/webpack-contrib/sass-loader/commit/96184e1)) - source map generation depends on the `devtool` option ([#​743](https://togithub.com/webpack-contrib/sass-loader/issues/743)) ([fcea88e](https://togithub.com/webpack-contrib/sass-loader/commit/fcea88e)) - validate loader options ([#​737](https://togithub.com/webpack-contrib/sass-loader/issues/737)) ([7b543fc](https://togithub.com/webpack-contrib/sass-loader/commit/7b543fc)) - reworked error handling from `node-sass`/`sass` - improve resolution for `@import` (including support `_index` and `index` files in a directory) ##### Bug Fixes - compatibility with `pnp` ##### [7.3.1](https://togithub.com/webpack-contrib/sass-loader/compare/v7.3.0...v7.3.1) (2019-08-20) ##### Bug Fixes - minimum `node` version in `package.json` ([#​733](https://togithub.com/webpack-contrib/sass-loader/issues/733)) ([1175920](https://togithub.com/webpack-contrib/sass-loader/commit/1175920)) ### [`v7.3.1`](https://togithub.com/webpack-contrib/sass-loader/blob/master/CHANGELOG.md#​731-httpsgithubcomwebpack-contribsass-loadercomparev730v731-2019-08-20) [Compare Source](https://togithub.com/webpack-contrib/sass-loader/compare/v7.3.0...v7.3.1) ### [`v7.3.0`](https://togithub.com/webpack-contrib/sass-loader/blob/master/CHANGELOG.md#​730-httpsgithubcomwebpack-contribsass-loadercomparev720v730-2019-08-20) [Compare Source](https://togithub.com/webpack-contrib/sass-loader/compare/v7.2.0...v7.3.0) ##### Bug Fixes - handle module import ending `/` as module ([#​728](https://togithub.com/webpack-contrib/sass-loader/issues/728)) ([997a255](https://togithub.com/webpack-contrib/sass-loader/commit/997a255)) - resolution algorithm ([#​720](https://togithub.com/webpack-contrib/sass-loader/issues/720)) ([0e94940](https://togithub.com/webpack-contrib/sass-loader/commit/0e94940)) - use "compressed" output when mode is "production" ([#​723](https://togithub.com/webpack-contrib/sass-loader/issues/723)) ([b2af379](https://togithub.com/webpack-contrib/sass-loader/commit/b2af379)) ##### Features - `webpackImporter` option ([#​732](https://togithub.com/webpack-contrib/sass-loader/issues/732)) ([6f4ea37](https://togithub.com/webpack-contrib/sass-loader/commit/6f4ea37))
