The first major update to iOS 11 fixes the KRACK vulnerability and adds 70 emojis. Read on to learn more.

Since iOS 11 was released in September, Apple has released a few minor updates to fix a few early glitches. The major point update we all expected has been in the works since, but with Friday’s iPhone X launch on the horizon, the company finally took the 11.1 update out of beta this week.

Users can expect a lot of under the hood and some debatable user-facing improvements in this release. The new update is big on emojis, which are becoming as ubiquitous and essential as air it seems—over 70 of the expressive characters are included with this update. Read on to learn more about the update and whether you should get it now.

What’s New in iOS 11.1 and Why You Should Upgrade

Version 11.1 works on the following devices: iPhone 5s and later, iPad Air and later, and iPod Touch 6th generation. Apple has been consistent with the size of these updates, averaging around 275 to 280 MBs. iOS 11.1 is just 246 MBs for my iPhone 6s, making it smaller than average for a major update.

Now for a breakdown analysis of whats included.

Aside from the new emojis, iOS 11.1 also adds back the 3D Touch app switcher feature. This is the gesture that lets you open the app switcher by 3D touching near the edge of the screen went away with iOS 11, but now it’s been re-implemented.

via Apple

As with all point updates, you can download over Wi-Fi by opening Settings > General > Software Update, tapping Download and Install, entering your passcode then waiting. When complete, you can pause the update or install right away. Users on a slow connection can connect their Apple device to a computer running the latest version of iTunes then check for software updates.

So, should you get it? Yes, you should, but it never hurts to monitor social media for any early issues that might pop up. Me personally, I’m gonna guinea pig this one out for you. So, see you on the other side.
