Major release every 6 months, 2 major version deprecation policy.

There was definitely some initial pushback, but we hope to demonstrate with this release that it's a) not that scary and b) good for both developers and users.

Most devs should see significant reduction (upwards of 50%) in their output builds. We think that's a reasonable trade off for a couple hours of work to upgrade.

In this release, most developers should be able to simply update their dependencies and rebuild. We're aiming for regular, planned, minimal changes, rather than Big Bang style change from AngularJS -> Angular.

I think you're right. Probably something similar to how they changed Java from the 1.x to the 5, 6, 7... series. It did take a couple years for people to stop saying 1.5 though, as I suspect will be the case for people saying "Angular2" trying to find a way to distance themselves from Angular 1 but not really caring if some component was written for 4, 5, etc..

you'll find that generally, we refer to it as "Angular" or "Angular 4.0" - officially, AngularJS is 1.x.

We'll see how it shakes out, but so far our community has been pretty awesome about it.
