Earlier today, Apple continued its tradition of updating all of its operating systems at once. The day brought major new feature releases to iOS, iPadOS, macOS, watchOS, and tvOS. The iOS, iPadOS, and tvOS updates are numbered 13.4, Apple Watches got watchOS 6.2, and Macs saw the release of macOS Catalina 10.15.4.

For many of its platforms, Apple releases annual overhauls labeled, say, iOS 13, and introduces new features through the year with just one “dot”—hence iOS 13.4. Smaller, bug-fix oriented updates are usually labeled something like iOS 13.4.1.

As the nomenclature suggests, this is a feature update. For the most part, the big features introduced today were already rumored or known to be planned. The big three are arguably full trackpad and pointer support for recent iPad, iCloud Drive folder sharing, and universal app purchases.
