iOS 15.3 Beta 2 & iPadOS 15.3 Beta 2 Released for Testing
While Apple just released iOS 15.2.1 and iPadOS 15.2.1 update for all users, they also released the second beta version of iOS 15.3 and iPadoS 15.3 for users enrolled in the beta testing programs for Apple mobile system software.
Additionally, new beta versions of watchOS 8.3 and tvOS 15.3 are also available to users beta testing system software on those devices.
iOS 15.3 beta 2 and iPadOS 15.3 beta 2 presumably include minor bug fixes and adjustments to the operating systems for iPhone and iPad.
It is unclear if iPadOS 15.3 will include support for Universal Control, the hotly anticipated feature that allows a single Mac to control multiple Macs and iPads with a single mouse and keyboard. So far there is no mention of the feature, and it does not appear to be included in macOS Monterey 12.2 beta 2 which was also just released.
Users enrolled in the iOS and iPadOS beta testing programs can find iOS 15.3 beta 2 and iPadOS 15.3 beta 2 available to download now from Settings > General > Software Update.
Apple usually goes through several beta versions before issuing a final release, suggesting the public debut of iOS 15.3 and iPadOS 15.3 is at least a month out.
