CUPERTINO, Calif.—Apple's annual release cadence is like clockwork: Each September brings new iPhones as well as a new version of iOS for new and old iPhones—at least, those that are still supported. iOS 17 didn't get a mention during the show, but the official website is up with a September 18 date.

Whereas some recent annual iOS updates focused on rethinking or redesigning existing parts of the experience (like the home screen or widgets), iOS 17 is mostly about adding a plethora of new features. For example, it introduces a new mode called StandBy that allows it to act as a sort of smart clock with special widgets when it's placed in landscape mode while connected to power—"clock radio mode," if you will.
