Apple seeded to developers the release candidates for iOS 14.4 and the iPad equivalent on Thursday. It’s probably the last step before a public release. Among other changes, these new versions will apparently give iPhone and iPad users the option to block third-party applications from tracking them.
Devs can also install watchOS 7.3 RC and tvOS 14.4 RC, which became available Thursday too. But macOS Big Sur 11.2 is still on Beta 2.
