Apple today made iOS 7.1 available to iPhones, iPads, and iPods Touch. The operating system update resolves a significant bug that soft reset iOS devices when being used. iOS 7.1 also adds support for CarPlay, Apple's recently-announced in-car software. The update tweaks the behavior of a wide range of functions, such as the ability to control Siri manually by pressing and holding the home button. Siri gains more natural-sounding voices for Chinese, UK English, Australian English, and Japanese. iTunes Radio was improved with new placement of the search bar, and the ability to buy albums directly from the Now Playing screen. The Calendar app gains the ability to display events in the month view, as well as view country-specific holidays. Accessibility has been improved with a bold font option, and the Reduce Motion function now applies to more apps, including weather and messages. iOS 7.1 also adds new HDR camera tools, improves iCloud Keychain support, automatically clears FaceTime calls, improves Touch ID on the iPhone 5s, improves performance of the iPhone 4, and provides other UI teaks. iOS 7.1 is free to download from Apple.
