v4.0.0

This major upgrade moves from Webpack 4 to 5 together with improvements to the adapters. See beta releases for detailed description.

We created an upgrade guide to quickly move from webpack-config-builder 3.x to 4.x.
See UPGRADE-4.0.md

When upgrading please read the migration guide supplied by Webpack. As some settings / best practices are still done at application level.
