Apple Intelligence has been the focus of most iOS 18 updates so far, and we’re still waiting on the big Siri overhaul that adds personal context using the data on your phone and scores of new “app intents” that allow Siri to perform actions in apps. Those features are generally expected to come in iOS 18.4, which most believe will be released in March or April. I

The improvements in iOS 18.3 are relatively minor, but welcome, and there are lots of security fixes.

Update January 27: iOS 18.3 has now been released for all compatible iPhones, and iPadOS 18.3 for compatible iPads.
