Testing of both iOS 9.2 and OS X 10.11.2 continues, with the second pre-release builds of both platforms issued to registered developers on Tuesday.
The latest build of iOS 9.2 is identified as build 13C5060d. Apple has once again warned developers that devices running iOS 9.2 cannot be restored to earlier versions of iOS.
Its release comes just one week after the first developer beta of iOS 9.2 was issued. The most notable change in iOS 9.2 revealed by Apple is a change to how the Safari Web browser works in third-party apps, enabling user-installed extensions to operate in those conditions.
An initial public beta of iOS 9.2 was also released last week, on Thursday. It's likely that a second iOS 9.2 public beta will debut this week.
As for OS X 10.11.2 beta 2, it is identified as build 15C31f. It also saw its first developer beta launch one week ago, while the first public beta also debuted last Thursday, alongside iOS 9.2.
Finally, iOS 9.2 and OS X 10.11.2 were also accompanied by a new, second beta build of Xcode 7.2. Apple TV developers can also obtain a first beta of tvOS 9.1.
