 ## Exporting multiple configurations
 
-Instead of exporting a single configuration object/function, you may export multiple configurations (multiple functions are supported since webpack 3.1.0). When running webpack, all configurations are built. For instance, this is useful for [bundling a library](/guides/author-libraries) for multiple [targets](/configuration/output#output-librarytarget) such as AMD and CommonJS:

 W> With webpack 3.5.5, using `libraryTarget: { root:'_' }` doesn't work properly (as stated in [issue 4824](https://github.com/webpack/webpack/issues/4824)). However, you can set `libraryTarget: { var: '_' }` to expect the library as a global variable.
