Instead of bigger new features like Universal Control, iOS 15.5 offers updates to Apple Cash, Photo Memories and the podcasts app, to name a few. .

You can download iOS 15.5 by going to Settings > General > Software Update > Download and Install.

The biggest functional change in 15.5 is the inclusion of "Send" and "Request" buttons for Apple Cash.

Another change includes the iTunes Pass feature for Wallet being renamed Apple Balance

You'll now find a separate card in Apple Wallet for Apple Balance, similar to how a credit card shows up in your Wallet. 

But MacRumors found references to a new Apple Classical app in the 15.5 beta that seems to be the endgame for Apple's acquisition of classical music streaming service Primephonic last year

iOS 15.5 also offers more support for SportsKit as Apple brings live baseball into its content catalog.
