what changed in watchos

In watchOS 26, several updates and new features have been introduced:

1. Design System: watchOS 26 features a new design system with updates to materials and controls, including changes to app icons and system spaces like the Watch face and Control Center. The new design, called Liquid Glass, provides a fresh look while maintaining familiarity.

2. System Architecture: The new system architecture supports Apple Watch Series 9 and later, using the ARM64 architecture. This requires developers to ensure their apps are compatible with this architecture.

3. Intelligence and Proactivity: watchOS 26 uses intelligence to better understand user needs and proactively provide relevant information. This includes enhancements to the Smart Stack, which now offers more expressive experiences and improved prediction algorithms.

4. MapKit Enhancements: New features for MapKit allow users to search for nearby points of interest, get routes using different transport types, and show routes as overlays on a map with SwiftUI.

5. Widgets and Controls: Developers can now add controls to the Control Center and Smart Stack, allowing users to perform quick actions without opening the app. Widgets can also receive push updates to keep data current.

6. Fitness and Health: New fitness features include a Workout Buddy and enhancements to the Workout app, such as custom workout suggestions and media features integrated with Apple Music.
