+### BREAKING CHANGES
+
+* Router is updated to Angular Router Component. Old beta router is removed.
+That means that all the routes are moved to the `src/app/app.routes.ts` file. `src/app/app.menu.ts` is also merged into the routes configuration.
+More details on how to configure a new route you can find [here](https://akveo.github.io/ng2-admin/articles/015-sidebar/).
+
+* Forms are updated as well. Thus you need to reconfigure all your forms to use new Angular Forms. Checkout the `src/app/pages/login/login.component.ts`component for more details and example.
+
+### How to update
+
+* run `npm install`
