Hmmm...ok. I agree, we should allow people to continue to use older versions...their tests may break on 4.1.2. 

How would we ensure everything is working against older versions? Is there a way to run all the Robolectric tests against each supported SDK, in turn?

We were hoping to get this merged after 2.2 is released so people who are pinned to 2.2-SNAPSHOT wouldn't break. Given that, do you think this could be merged then, and multi-SDK support added in after that?
