I think it's losing a lot of steam to React, rather than to the changes in ng2

The stats says no.

Re @jtmarmon, they both seem to be doing well.

Locking both down to a category of programming, in 2016 both seems to be getting the same amount of interest.

I voted no because I'm not sure if Angular is losing it's charm. I will say that I'm more interested in learning React over ng2 but I would need more data to make an informed decision about which way to go.

React has more buzz in my circles, especially at startups working on new apps. But for larger organizations with existing codebases or requirements of platform stability, they seem to be focusing a lot of energy on ng1.X.

It's nothing like "breaking changes". It's a different framework with "Angular" branding. But it's still pretty good to be thought about of using it.
