What's New for Developers
Compose Multiplatform v1.8.0-alpha01 significantly improves iOS accessibility with VoiceOver enhancements and adds cross-platform deep link navigation with browser support. The release modernizes test infrastructure for consistency with Android behavior and introduces Variable Fonts support. Notable additions include web resource preloading APIs and expanded Gradle plugin capabilities for library targets.
