Apple released iOS 7.1 yesterday. I am updating my phone right now - however, changes are rather minor and as you would expect for a .1 Release more or less bug fixes and tweaks.
Apple releases iOS 7.1 with CarPlay support
Unfortunately I do not have the Ferrari that goes with this Update - so I wont experience iOS CarPlay any time soon.
Apple TV got updated too - with some nice enhancements when it comes to change and control your Home Screen.
