The biggest changes are in the Messages app - with the option to send messages in "invisible ink" which the recipient has to swipe to see, the addition of visual effects, and a new feature that lets you sketch your thoughts.The Music app has also been given a major redesign, with a bold new look and simplified menus. As well as these flagship changes, the software has numerous tweaks and polishes across the board. Want to update today? Here's how.
