Apple released its latest mobile operating system update on Monday, iOS 7.1. The major upgrade packs an assortment of bug fixes, improvements, new features and some subtle changes to the overall interface, CNN reported.

iOS 7.1 is the first major update to the iPhone, iPad and iPod Touch operating system since iOS 7 was released in September 2013.

There are some welcome repairs in 7.1. The update improves the accuracy of the fingerprint sensor on iPhone 5S devices. Minor upgrades include an additional way to activate Siri. The camera on the iPhone 5S will now automatically detect scenes it thinks can benefit from high-dynamic range. iTunes Radio, the Calendar App and FaceTime have all added minor improvements, and there are a handful of accessibility tweaks aimed at making the OS work better for the visually impaired.

The big new feature in 7.1 is CarPlay, a tool for pairing an iPhone 5 and newer smartphones with select in-car systems.
