will release brand-new software for iPhones and iPads in the coming weeks. It's called and it's the latest software from Apple that will also be available on Apple's new iPhones. CNBC has been playing around with the new software for several weeks and, in anticipation of the release, decided to share a few of the best changes.

1. Run multiple apps side by side

The major changes in iOS 11 will depend on what device you're using the software on. With iOS 11 on iPads, you'll have useful new multitasking features that allow you to drag and drop photos from one app to another (the web browser into an email, for example), or launch a new "slide over" window pane that lets you control apps such as messages while interacting with two other applications in split screen. That's just a taste.

2. Apple Pay is making a run at Venmo

You might have used Apple Pay on your current iPhone. You can tap your iPhone at thousands of retailers to buy products even if you left your wallet home. In iOS 11, Apple will roll out new functions for Apple Pay. You'll be able to request, send and receive money using your linked credit card account. Money will then be stored on a card in your Apple Wallet for spending anywhere Apple Pay is accepted, or for transferring to your bank. Yeah, watch out Venmo.

3. Siri works better and sounds more human

There are a lot of changes coming to Siri, too. I've found that she (or he, depending on the voice you use) has been much more accurate in understanding what I'm asking. Also, Apple has tweaked the voice of Siri so that it sounds more human and less robotic. Siri will also help you translate from a variety of languages in iOS 11.

4. 'Do not disturb' mode for driving

There's a new mode in iOS 11 that should keep us all safer, so long as you activate it. It's called "Do not disturb while driving" and you can turn it on to prevent yourself from seeing any notifications as they come in. Sure, it can be frustrating if someone needs to reach you while you're on the road, but it's much safer than trying to text or answer a phone call while you're cruising in the highway's fast lane.

5. Augmented reality will let you mix real-world scenes into apps
