v4.0.0 Migration Guide
FYI: v4 drops support for Node 6 and 7. If you need support for versions of Node that have reached EOL, please use v3.
There is a new Node.js API available. Please see the docs.
package.json configuration property name change
It is possible to specify configuration in your package.json file. In v3, the property name was
npmPackageJsonLintConfig. This must be changed to
npmpackagejsonlint in v4.
