OS 8.1 is available for download now

Apple's new iPhone and iPad update, iOS 8.1, is officially out. The biggest addition is support for Apple Pay on the iPhone 6 and 6 Plus models.

Apple Pay is a new feature that allows you to make payments with your iPhone 6 or iPhone 6 Plus. Because the new phones have near-field communication built in, you can simply tap your phone to purchase items at Walgreens, McDonald's, and other retailers. You can also use Apple Pay to make in-app purchases as well.

Other than Apple Pay support, iOS 8.1 fixes a handful of bugs that pertain to Wi-Fi connectivity among other issues. The update also allows iPhones and iPads to communicate with your Mac through a feature known as Handoff, which is new to iOS 8.1 and OS X Yosemite.

Here's the full list of changes:

Adds an option to select between 2G, 3G, or LTE networks for cellular data

Fixes an issue in Safari where videos would sometimes not play

Adds AirDrop support for Passbook passes

Adds an option to enable Dictation in Settings for Keyboards, separate from Siri
