v7.0.0

Compare Source

Features

• Refactor resolving and simplify webpack config aliases (#​479) (e0fde1a)
• Remove node-sass from peerDependencies (#​533) (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 (2018-03-03)

Bug Fixes

• package: add webpack >= v4.0.0 (peerDependencies) (#​541) (620bdd4)

Performance Improvements

• use neo-async instead async (#​538) (fab89dc)

6.0.6 (2017-06-14)

Chore

• Adds Webpack 3.x version range to peerDependencies
