The upgrade to Kotlin 2.4.0 is a high-risk change. It removes the K1 compiler frontend and promotes several previous compiler warnings to errors, which can cause build failures for projects that have not already addressed them.

Key Breaking Changes

• K1 Compiler Removed: Support for -language-version=1.9 has been completely dropped. Projects that were pinning this version to use the K1 compiler must be fully migrated to the K2 compiler before upgrading. [5, 6, 7]
• Compiler Warnings Are Now Errors: Code that previously compiled with warnings will now fail. This includes:
  • Stricter Inline Function Visibility: Public inline functions are no longer allowed to expose internal or private types or declarations in their signature or body. [2]
  • Stricter Java Nullability: The compiler now strictly enforces nullability from Jakarta @Nullable and @Nonnull annotations when interoperating with Java code. [2, 6]
  • Inaccessible Types: The compiler will now fail the build if your code implicitly uses a type from a transitive (indirect) dependency without declaring it as a direct dependency. [2]

Environment & Tooling Changes

• Raised Apple Target Versions: For Kotlin Multiplatform projects, the default minimum supported versions for Apple targets have been increased: iOS to 15.0, macOS to 12.0, and watchOS to 8.0. [1, 4]
• Android Gradle Plugin (AGP): The minimum required AGP version is now 8.5.2. [5]

New Stable Features

This release also stabilizes many previously experimental features, including context parameters, explicit backing fields, and a common kotlin.uuid.Uuid API. [1, 3, 4]

Recommendation: Before upgrading, ensure your project is fully migrated to the K2 compiler and does not rely on -language-version=1.9. Resolve all existing Kotlin compiler warnings, especially those related to inline function visibility and Java nullability, as they will become build-breaking errors.
