v1.8.0-RC

Kotlin v1.8.0-RC delivers critical stability improvements across the compiler, JavaScript backend, and Gradle integration. This release fixes severe bugs affecting Enum constants, incremental compilation, and cross-module references, while enforcing safer concurrency patterns by forbidding @Synchronized on suspend functions. Enhanced toolchain support and improved error messaging make this a more robust foundation for mobile and multiplatform development.

Highlights

• Forbid @Synchronized annotation on suspend functions for safer concurrent code
• Fixed critical compiler bugs including StackOverflowError with Enum constants
• Resolved JavaScript incremental compilation issues with cross-module references
• Updated Native platform libraries to support Xcode 14.1
• Improved Gradle toolchain configuration for jvmTarget consistency
• Enhanced serialization plugin error messages for better debugging
