Here is what the change log shows for updates:

Fixed preference groups to appear with correct headings
Cleaned up orientation changes and fixed scrambled screen bug
Added NSAutoreleasePool
Added LayerKit transitions for aesthetics

There are also nice transitions from the menus to the games with the controller smoothly gliding in. So it’s prettier and more organized
