JetBrains Releases Kotlin 2.4.20 Beta1 With StackTraceRecoverable and 3 Build Targets

1 articles · Updated · InfoWorld · Jun 30

Summary

  • June 24’s Kotlin 2.4.20 Beta1 adds the StackTraceRecoverable interface and extends the build tools API to Kotlin/JS, Kotlin/Wasm and Kotlin metadata targets.
  • StackTraceRecoverable improves integration with kotlinx.coroutines by letting developers define how exception instances are created for stack-trace recovery without adding a dependency on that library.
  • The beta follows Kotlin 2.4.0, released June 3, which introduced experimental compile-time constant improvements for numeric and string operations and the IntrinsicConstEvaluation annotation.
  • Kotlin 2.4.0 also expanded JavaScript and TypeScript export support, enabled Java 26 bytecode generation and added experimental support for the WebAssembly Component Model.
  • JetBrains said Kotlin 2.4.0 is already included in IntelliJ IDEA and Android Studio, with another update to the 2.4.0 line due soon.
