I've built a small project using v2 and it really helped me get up to speed and learn some of the best practices for React front-end development. I'm looking forward to trying v3, because it addresses a several things that I felt could be improved in my current project. Specifically, Component tests, CSS organization, & integration with utilities like ImmutableJS & reselect.

That's so great to hear, you're going to love v3!

v2 to v3 is like stone age to modern times. :)
