Next month we should see iOS 7.1 released; here are some of the changes
Coming to the calendar in iOS 7.1 is a new list of events for those who need a quick run down of their upcoming appointments. It is accessible through a tap on an icon to the left of the magnifying glass. A "button shapes" feature inside the Accessibility settings allows those who need help, figure out where on the screen they need to tap or click to get certain features to work. Following the update, adding a number you've just dialed to your contacts list will be as simple as clicking on a circled plus sign to the left of the number. Previously, there was an "Add to Contacts" line under the number.
Of course, the usual bug fixes and performance enhancements will be included.
