How to track Android Studio Updates?

Is there a wiki / web page somewhere that shows which version of IntelliJ corresponds to which version of Android Studio?

For example, today Android Studio v. 0.6.1 was released. How can I know when those changes have been incorporated into IntelliJ 13.xxxx ? (I grab pretty much every EA made available, so it'd be nice if the information was at that level.)

Thanks,
