Angular 2 rc.5 is out!
It contains 18 breaking changes, over 40 new features, and 80 bug fixes.
RC 5 brings with it the significant new ngModule feature along with updates to forms, the router (Lazy Loading), material design, and more!
This is the first RC of the new router. You can find out more about the router in Victor Savkin’s new e-book.
The associated Angular team blog post is located here: http://angularjs.blogspot.com/2016/08/angular-2-rc5-ngmodules-lazy-loading.html
The migration guide used to be found in the Angular 2 docs here but it has been removed. If you need help with upgrading from the RCs, please see my blog post on this topic.
