Apple has released the fourth beta of its upcoming visionOS 27 update to developers for testing. This beta arrives two weeks after the previous release and introduces significant enhancements to the Apple Vision Pro experience.

Key features include the integration of Siri AI, a more capable version of Siri that can answer contextual questions based on what the user is viewing. Users will also notice a new Siri orb that can be placed in their virtual space. The update allows panorama photos to be transformed into spatial environments and introduces a new Icelandic environment called Thórsmörk. Additionally, web environment support enables developers to create 360-degree browsing experiences in Safari.

Further refinements include curved app windows for increased immersion, a reorganized Control Center for easier navigation, a smaller widget size, and notifications that automatically expand when focused on. These updates aim to enhance the overall usability and immersive capabilities of the Apple Vision Pro platform. More details on visionOS 27 features can be found in Apple's Vision Pro roundup.
