The latest on Apple releasing iOS 15.4

What’s new in iOS 15.4?

First, a review of what’s new in iOS 15.4. For a mid-cycle update, iOS 15.4 includes quite a few new features. The biggest change, however, is support for using Face ID while wearing a mask.

While Apple rolled out support for Apple Watch Unlock on iPhone last year, we now know that the feature was designed to be a temporary solution. iOS 15.4 has a much more advanced implementation using Face ID and masks. Apple explains that it's scanning "unique characteristics around the eyes" to authenticate you using Face ID while wearing a mask.

The downside here is that the new “Use Face ID with Mask” feature is limited to iPhone 12 and newer, so if you have an iPhone X, iPhone XS, or iPhone 11, you won’t be able to use this New features.

At the same time, iPadOS 15.4 and macOS 12.3, which are expected to be released together with iOS 15.4, also bring support for Universal Control. First announced at WWDC last summer, Universal Control lets you control multiple iPads and Macs using a single mouse, keyboard, and trackpad.

Here are some other new features in iOS 15.4:

• Over 37 new emojis
• Home screen widgets for Apple Wallet and Apple Card
• New custom email domain feature in Settings
• Deeper SharePlay integration
• Shortcut improvements
• Add notes for iCloud Keychain password

When will iOS 15.4 be released?

iOS 15.4 is currently in beta testing for developers and public beta users. Apple typically releases a new beta every two weeks, with a cycle of between four and six.

Apple is currently aiming to release iOS 15.4 sometime in the first half of March. This is consistent with reports that Apple plans to hold a virtual event on March 8 to announce the new iPhone SE as well as the updated iPad Air.

With that in mind, it seems likely that Apple will devote time to iOS 15.4 at its rumored event on March 8. From there, we'll likely see a launch a week later. Apple likes to release new software updates on Tuesdays, so releasing iOS 15.4 on March 15 would certainly make sense.

If you want to try out all the new iOS 15.4, iPadOS 15.4, and macOS 12.3 features now, Apple does have a public beta testing program. If you're interested in signing up for Apple's public beta testing program, you can do so through Apple's website.

But keep in mind that beta software often comes with quite a few bugs, glitches, and other performance issues. This means your battery life may be worse than usual, some features may not work as expected, and there may be issues with third-party apps.
