The end-of-cycle updates are often devoid of anything user-facing, but that doesn't mean you should delay updating to visionOS 26.6. Security patches and preparation for Siri AI are worth the update. Apple has released visionOS 26.6 today alongside the other operating systems with minor changes. The release build for visionOS 26.6 is number 23O770. Even though users won't get any new user-facing features, there has been some evidence that Apple will begin indexing users' devices before releasing Siri AI in September.
