Apple is not only working on iOS 8.2, but the company released the first beta of iOS 8.3 to developers on Monday. Apple is also simultaneously working on iOS 8.4 and iOS 9.0, according to a report from 9to5Mac. iOS 8.0 was released on September 17, 2014, two days before the release of the iPhone 6 and 6 Plus. Apple called it. "the biggest change to iOS since the introduction of the App Store," but the OS stumbled out of the gate shipping with a bug that caused issues for HealthKit-enabled apps. iOS 8.0.1 was released to fix the HealthKit related bug, but the update caused some users to lose access to their cellular data and Touch ID. iOS 8 finally got rolling a few days later with the release iOS 8.0.2.
iOS 8.1 was eventually released to add Apple Pay support for the iPhone 6 and 6 Plus, and iOS 8.1.3 launched a few weeks ago to improve stability and performance.
Apple seeded the fifth beta of iOS 8.2 on Feb. 2, 2015. The next major update is mostly focused on the Apple Watch. It will include Apple's WatchKit API for app developers and a few bug fixes. iOS 8.2 also reintroduces blood glucose tracking in the Health app. iOS 8.2 is expected to launch in late-March or early April before the release of the Apple Watch.
