Continuing its beta testing process for this series, Apple has issued fourth developer builds of watchOS 11.1, tvOS 18.1, and visionOS 2.1.
watchOS 11 introduces better cycle tracking, more customizable Activity Rings, and more personalization.
This period of beta releases is a bit unusual, as Apple is providing builds in two distinct groups. This is caused by the beta testing of iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1, to hammer out issues with Apple Intelligence.
Since those three have been in testing far earlier, the beta is split into two groups, with Apple Intelligence-infused builds separate from others that don't have it.
The third builds of watchOS 11.1, tvOS 18.1, and visionOS 2.1 arrived on October 1. However Apple pulled the beta for watchOS 11.1 on October 3 due to some models locking up while running it.
Apple's tvOS 18.1 beta shifts to 22J5567a from 22J5557d, watchOS 11.1 is on build 22R5569a from 22R5559b, and visionOS 2.1 goes to 22N5567a following the previous build, 22N5558e.
At this early stage, it is unclear what is new in the three just-released builds.
AppleInsider and Apple strongly advise that users do not install test operating systems or other beta or RC software onto "mission-critical" or primary hardware, due to the small chance of issues that could result in the loss of data. Testers should therefore use secondary or non-essential devices and make sure they have sufficient backups of any critical data.
