Apple seeded watchOS 4 beta 8 to developers on Thursday, build (15R5371a). Apple didn’t include patch notes for the release, but as with other operating systems in Apple’s developer beta program, each seed is a mix of bug fixes, tweaks, and various stages of feature rollouts.
watchOS 4 includes several new watch faces, including a Siri watch face. Also included are a new app dock, a flashlight feature, and tons of interface improvements, including enhancements to the Workout and Music apps.
Monday’s release continues an accelerated release cycle, as the last round of developer betas hit just one week ago. Apple is expected to ship watchOS 4 in September.
