Kotlin 2.2.20 Released

Sarah Haggarty

The Kotlin 2.2.20 release is out, delivering important changes for web development. Kotlin/Wasm is now Beta, with improvements to exception handling in JavaScript interop, npm dependency management, built-in browser debugging support, and a new shared source set for js and wasmJs targets. Additionally, here are some main highlights:

• Kotlin Multiplatform: Swift export available by default, stable cross-platform compilation for Kotlin libraries, and a new approach for declaring common dependencies.
• Language: Improved overload resolution when passing lambdas to overloads with suspend function types.
• Kotlin/Native: Support for stack canaries in binaries and smaller binary size for release binaries.
• Kotlin/JS: Long values compiled into JavaScript BigInt.

For the complete list of changes, see What’s new in Kotlin 2.2.20 or the release notes on GitHub.
