What are the breaking changes that caused the bump to 3.0.0? I don't see release notes or a change log that makes that clear. It wasn't immediately clear by looking through the commit history.
39 is in some ways a bug fix. Immediately executing every file you pass to proxyquireify as was happening prior to 3.0 is clearly wrong. But with a test utility it can't hurt to be conservative with versioning.
