Among other things, Apple will announce iOS and iPadOS 16, macOS 13, and watchOS 9 at the conference, but those updates won't arrive until later this year.

Today's iOS update offers just enough new user-facing features to earn that 15.x label instead of 15.x.x, which is usually reserved for bug fixes and the like.

And 15.5 allows the iPhone to be used as a point-of-sale device without any additional hardware, as reported in February.

On the macOS side, Apple names just two user-facing changes in its release notes.

It adds support for Studio Display Firmware Update 15.5 (which claims to improve webcam performance on Apple's new monitor), and the built-in Podcasts app gets the same new feature that iOS did.

Studio Display Firmware 15.5 attempts to address some user complaints about the monitor's webcam quality.

Apple hasn't shared any details about what's in the HomePod firmware update or tvOS 15.5.
