The update made it compatible with iOS 7.0, as well as changing the minimum required OS to 6.0. Most people are on 6 or 7 at this point... no need to really support 5 anymore.
Also made a few tweaks to the logic, menu button updates and minor bug fixes. There's still a slight problem with stuttering for Retina iPads, and I have an update for landscape mode in the works. It's been slow going since I've been so busy lately. Hopefully I'll have it done soon.
