Kotlin 2.0 is out
published on 2024/05/22
The road to the K2 compiler has been a long one, but now the JetBrains team is ready to announce its stabilization. In Kotlin 2.0.0, the new Kotlin K2 compiler is used by default and it is Stable for all target platforms: JVM, Native, Wasm, and JS. The new compiler brings major performance improvements, speeds up new language feature development, unifies all platforms that Kotlin supports, and provides a better architecture for multiplatform projects.
The JetBrains team has ensured the quality of the new compiler by successfully compiling 10 million lines of code from selected user and internal projects. 18,000 developers and 80,000 projects were involved in the stabilization process, trying the new K2 compiler in their projects and reporting any problems they found.
What a fantastic release. Congratulation for the team and community behind it.
