Overview

  • Developer beta 7 (build 23A5326a) arrived alongside matching seventh betas for iPadOS 26, macOS Tahoe 26, watchOS 26, tvOS 26, and visionOS 26.
  • A new Adaptive Power Notifications toggle lets users get alerts when the battery‑extending Adaptive Power mode activates.
  • The latest betas include a redesigned Blood Oxygen feature for Apple Watch Series 9, Series 10, and Ultra 2 models sold in the U.S. since mid‑January 2024.
  • Apple also released the fourth public betas, which correspond to the new developer builds and continue refinements to the Liquid Glass design.
  • iOS 26 supports iPhone 11 and newer, while Adaptive Power and other Apple Intelligence features require iPhone 15 Pro or any iPhone 16 model; Apple advises testing betas on secondary devices with backups.
