You can’t get a new iPhone 6 or iPhone 6 Plus until Friday, but iOS 8, the latest version of Apple’s mobile operating system, goes live on Wednesday. The free download will be available to anyone with an iPhone 4S, 5, 5C or 5S. iOS 8 isn’t the game-changing upgrade that iOS 7 was, but it has a handful of new features that Apple users are bound to enjoy:

Device Continuity
When Apple’s Mac operating system, OS X Yosemite, is released, it will pair with iOS 8 for the tightest integration ever between devices. Users will be able answer their phone or receive texts on desktop or laptops and move documents from mobile devices to computers with a single swipe. That feature, called Handoff, will work with a variety of apps, including Mail, Safari, Pages, Numbers, Keynote, Maps, Messages, Reminders, Calendar and Contacts.

Widgets
Apple has kept strict controls on how apps appear on the iPhone and iPad. But now, the iOS 8 has given developers the ability to create widgets. While this ability has been available on Android devices since their inception, it will be limited to the “Today” screen under the device’s Notification Center.

Keyboard changes
iOS 8 brings the first change to the system’s keyboard since the iPhone was introduced. Third-party typing apps, like Swype, and tools, like QuickType, will allow a more integrated predictive texting system.

What’s that song?
Siri will be integrated with Shazam, an app that recognizes music and other media playing around it.

Family Sharing
In the new system, up to six people will be able to share purchases from iTunes, iBook and the App Store without having to share a single account. There’s a shared family calendar so anyone can keep everyone abreast of plans and a family photo album that can be shared as well. A new “ask to buy” function will also be available. This will ping parents, letting them give or withhold permission when a child tries to buy something from Apple.
