Apple introduced bug fix updates for every one of its operating systems on Thursday. These updates should improve the battery life on iPhone and iPad. And for Mac users, the new version fixes well-publicized bugs recently introduced by macOS 12.3.
However, there are no new features in macOS Monterey 12.3.1, iOS 15.4.1, iPadOS 15.4.1, watchOS 8.5.1 and tvOS 15.4.1 — Apple just fixed small problems. All five updates are available to download immediately.
