I've just given it a really quick go and it just seems to work for MOST of what my code does right now (at least what I have covered by automatic tests.)
I recently added some witness checking code and that appears to break and I've put an issue in Github for you to see. I think it's just obscure bits of Beem which can be done another way now.
Fixes should be in now. Let me know if anything else comes up.
