[Update: iOS 12.1 has now been released!]
Apple has confirmed that iOS 12.1, the first major update to iOS 12, will be released today after the Apple Event in New York. The event is slated to end around 9:00 am Pacific and you can expect the new version to drop around 10:00 am Pacific at the latest.
iOS 12.1 has been in beta now for a couple of months and has had five beta builds to this point. With this new version, there are a lot of new features and improvements that will be coming to your compatible iPhone and iPad.
The first big feature is Group FaceTime. With this enhancement to FaceTime, you will be able to video and audio chat with up to 32 people at once. This feature had been slated for iOS 12 but got pushed back to the .1 release because of stability challenges. Keep in mind that not every iPhone or iPad will be able to do video calls. Older devices, listed here, will only be able to do audio calls.
Second, Dual-SIM support will be coming to the iPhone XS, iPhone XS Max, and iPhone XR. Here in the United States, that means that the eSIM feature on your phone will be enabled with this update. It then becomes a question of when carriers will fully support it. That should tomorrow too but you need to check with your carrier to make sure.
Third, real-time depth control for the iPhone XS, iPhone XS Max, and iPhone XR. This will allow you to adjust the background blur of your photos before you take them. Right now, it is only a post-processing feature.
Finally, there are 70 new emoji coming in this update to all iPhones and iPads. These new emoji cover a wide range of people, foods, and other objects that you can add to your email and messages.
All-in-all, iOS 12.1 is a solid update and one that users will want to download as soon as it is available. Remember, to check for the update, go to Settings>General>Software Updates on your iPhone or iPad to check for and get the download.
