what is new in watchOS

In watchOS 26, Apple introduced several new features and updates:

Design System: watchOS 26 features a new design system with changes to materials and controls, including updates 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.
System Architecture: Apple Watch Series 9 and later, as well as Apple Watch Ultra 2, now use the ARM64 architecture. This requires developers to ensure their apps are compatible with this architecture.
App Integration: Apps can now be integrated into more places on the Apple Watch, such as the Control Center and Smart Stack, using WidgetKit. This allows for quick actions without opening the app.
MapKit Enhancements: New features for MapKit in watchOS 26 include searching for nearby points of interest, getting routes using different transport types, and showing routes as overlays on a map with SwiftUI.
Widget Updates: Widgets can now receive push updates using APNs, ensuring that widget data remains current.
