Apple just released iOS 9.2.1 for iPhones, iPads and the iPod touch. It’s available for all right now, and follows in the footsteps of the last major release back in December. iOS 9.2 was released last month with plenty of brand new features, and today’s iOS 9.2.1 update seems to just build a bit on that.

The official changelog from Apple is brief, and simply states: “This update contains security updates and bug fixes including a fix for an issue that could prevent the completion of app installation when using an MDM server.”

An MDM server is otherwise known as a “mobile device management” server, usually used by enterprise and education institutes to deploy apps across multiple devices at the same time. That fix might not be big for most of us, but it’s a big deal for folks who rely on that technology.

You should find the update available in your device’s settings menu now.
