New York (CNN Business) After months of waiting , Apple's new software update for iPhones is almost here.

iOS 13, the latest version of's mobile operating system, will officially be available on Thursday for anyone with an iPhone 6S model or later. The update promises a number of significant changes.

Here are some of the key iOS 13 features that Apple has teased so far:

Dark Mode

Perhaps the single most buzz-worthy update in iOS 13 is dark mode . Apple will give users the option to have a dark background that is said to be easier on the eyes and potentially better for battery life. Some prefer it purely as a stylistic choice.

Swipe to type

Tired of punching in one letter at a time on your phone's keyboard? Apple is set to introduce a new Quickpath keyboard, which lets you swipe to type more quickly, similar to how Google's Gboard works. Until now, Apple users interested in this option have had to rely on apps from other developers, such as SwiftKey.

A new privacy feature

The company has a new feature that lets you log into third-party apps and websites using your Apple ID. As part of this option, called Sign in with Apple, you can even choose for Apple to generate an email address for you to log into these services, thereby limiting the amount of personal information you have to provide.

Maps

Apple Maps — if you use it — is getting a few updates. For one, you'll be able to explore cities in 3D. With the updated Apple Maps, you'll also be able to favorite spots you frequent and create collections of places you want to visit.

Siri

While Siri didn't get much mention during Apple's September keynote this year, the voice assistant is getting some changes. Siri will soon be able to read your incoming messages to you and let you share audio from your AirPods.
