Why was Angular 3 skipped, and what are the major differences in Angular 4 beta

Question

I just noticed that the Angular 4 beta was released, but cannot find much info on it. I'm making an app in Angular 2 right now and am kind of scared that Angular 4 is what I should be using.

What are the differences? Why did the team skip Angular 3, or have I just been living under a rock?

Answer 1

• Angular is being developed in a MonoRepo it means a single repo for everything. @angular/core, @angular/compiler, @angular/router etc are in the same repo and may have their own versions.
• The advantage of MonoRepo is, you don’t have to deal with the versioning of the code dependencies.

• Now the problem is with the @angular/router which is already in a 3.X version. And that’s because of some active and huge developments on the router section, like route-preload.
• Now releasing Angular as version 3, with its router on version 4 will create confusion
• To avoid this confusion they decided to skip the version 3 and release with version 4.0.0, so that every major dependency in the MonoRepo are on the right track.
