Is pr3 backwards compatible with 1.1?

[profunctional]

Tried to migrate 1.1 to pr1 and it was horrible. Is pr3 any better?

Going from 1.1 to 2.0 will require some migration. The class system, MVC, and other architecture is different. This article might help:

We will be coming out with a tutorial/guide about migration as we move towards GA release. Either way, you can't just simply slap ST2 in with ST1 code and vice-versa.
