After nearly three months after it was announced, Apple has officially released iOS 9 today.

One of the biggest improvements iOS 9 has over previous iterations of Apple mobile OS is its ability to multitask. With SplitView and SlideOver, you can access your apps much faster than you could in the past, with the latter of the two allowing two apps to run at the same time. Unfortunately, SplitView is only currently available for the iPad Air 2, but we know the iPad Pro will also support it when it launches later this year.

iOS 9 also brings improvements to Siri that offer a smarter way to interact with her. Such features like making specific requests to content based on time and location and Proactive, which optimizes Siri depending on what you’re doing, round out some of the ways Apple has improved her. The new OS also features an improved Spotlight search as third-party apps can now be brought up directly within a search.

Apple has also improved its Maps app to offer transit directions, includes Loyalty Card support in Apple Pay, and has a new News app. The new OS also makes it possible for the iPad to use a virtual trackpad by placing two fingers on its virtual keyboard.

iOS 9 is now available to download and weighs in at 1.2GB, which should make the process of updating your iOS devices less time consuming.
