On Tuesday, Apple stopped signing the iOS 12.1 public release, preventing downgrades from iOS 12.1.1 or 12.1.2, which patched a variety of bugs and exploits that could potentially amount to something in the jailbreak community down the road.

In recent weeks, developers and public beta subscribers alike have been testing iOS 12.1. For iPhone XS and iPhone XS Max owners, this has meant taking a closer look at the new real-time Depth Control feature in the Camera app. Here's how it works.
iOS 12.1 has apparently fixed an issue that prevented some iPhone XS and XS Max units from charging when a Lightning cable was plugged in and the screen was turned off.
Apple has released the second iOS 12.1 beta to developers. The update offers Group FaceTime and various bug fixes. The company also released watchOS 5.1 beta 2 and tvOS 12.1 beta 2 to developers.
