8.0.0-beta.1

💥BREAKING CHANGE

The babelrc option was changed. It now only accepts true or false as valid option (similar to other babel packages) and does not allow setting a string. If you previously had a filename specified you need to change to extends

 {
   loader: 'babel-loader',
   options: {
-    babelrc: 'path/to/.babelrc',
+    babelrc: false,
+    extends: 'path/to/.babelrc',
   },
 }
