Unfinished? How about never finished. >Angular 2 is going to have breaking changes only every 6 months from now on. So the next one would be around February with Angular 3. Yes exactly, they’re also finally switching to semantic versioning which is a huge win in my opinion. IMHO, breaking changes every six months is the recipe for an shitshow of an ecosystem. http://juristr.com/blog/2016/09/ng2-released/
Ok, now try to find at least one framework without breaking changes after initial release. Code should evolve, planned changes is a graceful evolution.
React releases every 6 months or so, and puts deprecation warning on anything that is breaking in the next update, so you have a full year between any breaking features, and six months for everyone to update before they land.
