iPhone users likely received a recent notification about the latest update: iOS 26.2.1.

Available on eligible devices immediately, iOS 26.2.1 provides “support for AirTag (2nd generation) along with bug fixes,” according to Apple Support. The new update is necessary to connect a device with Apple’s new AirTag2.

Apple introduced AirTag2 on Jan. 26. Powered by Apple’s Find My app, AirTags allow users to keep track of their items by placing the small, round tracker in luggage, cars, bags and other personal items. AirTag was first launched in 2021.

What is AirTag2?

AirTag2 includes the same computer chip in the iPhone 17, iPhone Air, Apple Watch Ultra 3 and Apple Watch 11. This new chip allows users to find items up to 50% farther away than the original AirTag, according to an Apple news release. It also has a 50% louder chirp.

AirTag2 is available for purchase on the Apple website, in Apple Stores and through the Apple Store mobile app. The new AirTag costs $29 for one or $99 for a pack of four.

What were the big updates for iOS 26?

Apple launched iOS 26 in September 2025, in conjunction with the launch of the iPhone 17, iPhone 17 Pro and Pro Max, iPhone Air, three new Apple Watch models and the AirPods Pro 3. Perhaps the most noticeable feature of the new update is Liquid Glass, a new user interface design that features clear, more fluid elements.

iOS 26 also includes several new Apple Intelligence features, including Live Translation, which allows users to translate text messages, phone calls and FaceTime calls. Live Translation can also be used with the AirPods Pro 3, allowing a wearer to translate audio in real time.

The software update also includes more intuitive Apple Maps, passport storage in the Apple Wallet mobile app, and new call and text features, like Hold Assist, which allows users to keep their line with a live agent on hold.
