After a long duration with beta run-ins, Apple has finally released the first major its first major update to iOS 7. iOS 7.1 is set to bring a slew of new features, performance tweaks and customary doses of bug fixes to iDevices.

Major changes in iOS 7.1 include the new CarPlay feature, which we saw in the pre-GM builds, and finally showcased at the recent Geneva Motor Show. The CarPlay feature is very intuitive. It lets you navigate through your car via voice commands. Naturally, Siri will be at the heart of it, and will allow all sorts of things like managing music and dictating messages, without making contact with the phone itself. Quite handy!

UI changes include refinements to the phone dialler and power off area. The Music player has also received some treatment, with repeat and shuffle icons. There are a plethora of other features and fixes. You can check out the official changelog below:
