Content

The release contains the JVM version of Kotlin compiler and also one native system dependent version for every major platform (Linux, macOS, and Windows). Those binaries are built with Excelsior JET AOT compiler (https://www.excelsiorjet.com/) and have faster startup time which is suitable for building small files or scripts.
