Angular 2 — Google’s public goal: No more breaking changes after release 2.0

You aren’t wrong. There will be breaking changes but they are trying to limit the amount, and make them small and easy to fix, and scheduling when they will occur.

If you look at those issues, most of them are already closed (fixed for v2), and the few remaining ones are quite small which is inline with their goals.

Our comparison on this issue between React and Angular might not have been completely fair, both will have breaking changes. I’ve definitely experienced headaches with breaking changes using both React and Angular, my hope is that the more strict structure and planning with Angular heading forward will limit these headaches.
