Last week, this blog covered software updates that were either announced or teased by Apple including "CarPlay," which improves iOS integration in an automobile, and improved Touch ID operations.

Yesterday, Apple made these features official with the release of iOS 7.1. According to an article from GigaOM, this is the largest update to iOS 7 since the revamped version of the mobile operating system was released in September. Aside from CarPlay and Touch ID, the update also addresses the random reboot bug, Siri, iTunes Radio and improves performance and user interface tweaks.

Headlining the update is CarPlay. The system was unveiled last year at the company's annual Worldwide Developers Conference (WWDC) though at the time it was called "iOS in the Car." Now, drivers will be able to more safely use their iDevices when behind the wheel with an experience that is designed specifically for their automobile. It improves the ability to answer calls, and use Maps, Messages, Music and other third-party audio apps.

Siri has experienced a change. Now businesses can control how long Siri listens by holding the home button and releasing when you are done. More natural sounding voices were also added to select languages.

The UI changes are small but noticeable. They include tweaks to the phone dialer, power off, incoming call screens and keyboard.

For businesses using iPhones and iPads in the workplace, this update will require the IT department examine it before giving the green light for employees to update. With the help of an IT consulting firm that specializes in iOS management and Apple support, any company can speed up this process.
