:tada: *Kotlin 2.5.0-Beta2 is out! Here’s what’s new:*

:sparkles: <https://youtrack.jetbrains.com/issue/KT-88882|New Node.js provisioning toolchain>
:package: <https://youtrack.jetbrains.com/issue/KT-88868|New DSL for declaring npm dependencies>
:swift: Introduced a new <https://youtrack.jetbrains.com/issue/KT-87716|Swift export DSL> (<https://github.com/JetBrains/kotlin/blob/master/docs/build-tools/gradle/new-swift-export-dsl.md|documentation>). Swift Export now supports <https://youtrack.jetbrains.com/issue/KT-78747|Swift Package Manager integration>, including <https://youtrack.jetbrains.com/issue/KT-89803|self-contained Swift package generation>.
:mag: Unused-return-value checker enabled in `check` mode by default
:hammer_and_wrench: Full compatibility with  <https://youtrack.jetbrains.com/issue/KT-88594|Gradle 9.8.0>.
:new: We’re collecting feedback on Kotlin’s new separate compilation scheme — <https://youtrack.jetbrains.com/issue/KT-89725|KT-89725>

:warning: *Migration heads-up:*
• Running the compiler on a *JDK older than 17 now produces an error,* with a temporary opt-out available in 2.5.0. JDK 17 or newer will be required from 2.5.20-Beta1. Share any missing use cases in <https://kotl.in/kkdgyx|KT-88173>.
• The standalone `kotlin-js` <https://youtrack.jetbrains.com/issue/KT-85440|Gradle plugin has been removed>. Use the Kotlin Multiplatform plugin with a JS target instead.
• The legacy `swiftExport {}` DSL is <https://youtrack.jetbrains.com/issue/KT-87989|deprecated>; migrate to `export.swift {}`.
• Removed support for the <https://youtrack.jetbrains.com/issue/KT-85434|non-Build-Tools-API JVM compiler execution mode>.
Give Beta2 a spin and tell us what you think! :purple_heart: Report issues at <http://kotl.in/issue|kotl.in/issue> or share your feedback right here in Slack. :thread-please:
