     A possible plugin might be [babel-plugin-require-context-hook](https://github.com/smrq/babel-plugin-require-context-hook).
     [README](https://github.com/storybooks/storybook/tree/master/addons/storyshots/storyshots-core#configure-jest-to-work-with-webpacks-requirecontext)
 
+### Webpack 4
+
+Storybook now uses webpack 4. If you have a [custom webpack config](https://storybook.js.org/configurations/custom-webpack-config/), make sure that all the loaders and plugins you use support webpack 4.
+
+### Babel 7
+
+Storybook now uses Babel 7. There's a couple of cases when it can break with your app:
+
+  * If you aren't using Babel yourself, and don't have .babelrc, install following dependencies:
+    ```
+    npm i -D babel-loader@next
+    ```
+  * If you're using Babel 6, make sure that you have direct dependencies on `babel-core@6` and `babel-loader@7`.
+
 ## From version 3.3.x to 3.4.x
 
 There are no expected breaking changes in the 3.4.x release, but 3.4 contains a major refactor to make it easier to support new frameworks, and we will document any breaking changes here if they arise.
