Following the release of iOS 17 and iPadOS 17, Apple has restarted its beta-testing cycle once again, with the first developer betas of iOS 17.1 and iPadOS 17.1 now available for testing.
Developers taking part in the testing program can obtain the latest builds by visiting the Apple Developer Center or updating their iPhone or iPad through the Settings app. Public beta versions generally appear a short time after the developer versions, and participants can sign up through the Apple Beta Software Program website.
The latest build is number 21B5045h.
At this early stage, it is unclear exactly what is new in the betas, but it is likely to include multiple performance improvements, bug fixes, and potentially features that were intended for the first release but weren't quite ready in time.
AppleInsider and Apple strongly suggest users don't install test operating systems or other beta or RC software on "mission-critical" or primary devices, as there is the small chance of issues that could result in the loss of data. Testers should instead use secondary or non-essential hardware and ensure they have sufficient backups of their critical data at all times.
