It's a bit sad to think that all this knowledge I have of Angular 1 is now obsolete but I'm excited to dive into this new framework. If it's half revolutionary as Angular 1 was, it's going to be a pretty interesting time.
So I can understand if Angular 1.0 stopped working on Angular 4.0 or 5.0. Breaking apps just on one major revision number is really a bad way to manage frameworks.
So where does angular lie on that continuum?
