-## Webpack update
-
-We changed the build system between beta.10 and beta.14, from SystemJS to Webpack.

-To take advantage of these, your app built with the old beta will need to migrate.
-
-You can update your `beta.10` projects to `beta.14` by following [these instructions](https://github.com/angular/angular-cli/wiki/Upgrading-from-Beta.10-to-Beta.14).
