Apple is on its seventh round of developer betas for its milestone operating system test releases, with the company releasing seventh builds of iOS 14, iPadOS 14, and tvOS 14 to developers.
New betas can be downloaded from the Apple Developer Center by those taking part in the Developer Beta program, or as an over-the-air update for already-enrolled devices. Public beta versions typically arrive within a few days of the developer versions, accessible via the Apple Beta Software Program site.
The new betas for iOS 14 and iPadOS 14 are not the first of this round to be released. Apple issued the seventh build of watchOS 7 on September 1.
For iOS 14 and iPadOS 14, the Home screen and app interface have received changes, along with alterations to Messages and Safari, Siri's interface, and Maps. New additions include Sound Recognition alerts and CarKey, among other features.
The testing of macOS Big Sur, or macOS 11, is primarily a shakedown of the operating system ahead of its push towards Apple Silicon, but it will also naturally work with Macs using Intel processors. Changes include design updates within Safari, and Messages becoming a Mac Catalyst app.
AppleInsider, and Apple itself, strongly recommend users don't install the betas on to "mission-critical" or primary devices, as there is the remote possibility of data loss or other issues. Instead, testers should install betas onto secondary or non-essential devices, and to make sure there are sufficient backups of important data before updating.
Update: Apple has also released new versions of iOS 14, iPadOS 14 and tvOS 14 to members of the public beta program.
