The same day that Apple released iOS 11.2.1 to the public, the Cupertino company has unleashed a new beta update for developers to test out, too.
Apple today released iOS 11.2.5 beta 1 to developers. If you're a registered iOS dev, you can grab the update over the air on your device or by going to Apple's Developer Center on your computer.
Since this is the first beta release of iOS 11.2.5, it's not yet clear exactly what's included with this update. Considering that it's an 11.2.x update, though, it likely is a smaller update focused on bug fixes.
Also released today is watchOS 4.2.2 beta 1. Developers can get this update through the Watch app on their iPhone after installing the configuration profile from Apple's Developer Center.
