If there is something in 1.2.0 that has broken you in some way that you need an older version, that's a problem and we should look in to it. The story is intended to be similar for sdk moving forward ... but we're still pre-1.0, so that makes sense at the moment. I'm still interested in what specific issue you had, just to make sure we're aware of issues people are having. Thanks! Monty
