Apple is quickly acting on its promise to deliver some useful upgrades before WWDC. The company has released iOS 15.5 and its iPadOS 15.5 counterpart with improvements to both Apple Cash and (as mentioned earlier) Podcasts. Cash users can now send and receive money from their card, while Podcasts users can have the app automatically limit episode storage based on criteria like the number of shows or time since release.
A corresponding macOS 12.4 update adds the relevant Podcasts features. You can also grab a previously teased firmware fix for the Studio Display's mediocre webcam quality. Apple has also released watchOS 8.6, tvOS 15.5 and HomePod 15.5 updates, although those focus on bug fixes and performance rather than any significant features.
The iOS, iPadOS and macOS updates aren't huge, but that's not surprising. Apple has historically wound down significant upgrades to its current operating systems around this time of year. The focus now is likely on iOS 16 and other big revisions likely to arrive in the fall.
