Apple is reportedly launching an update to its iOS mobile operating system in March, according to 9to5 Mac.

The updates to Apple’s operating system are big events for users as they enable new features and fix bugs. The iOS 7.1 update will reportedly not have any major secret features. Instead, it will have user-interface tweaks in the iPhone app, an improved Calendar app, speed improvements, and a variety of bug fixes.

Apple hasn’t commented on the report. The publication said it believes an event would coincide with the release.
