We plan to release one more traditionally-versioned release as Kotlin 1.9, which will also include updates from the ongoing development of the K2 compiler frontend as it approaches stabilization. Keep reading to learn more about the roadmap for the Kotlin 2.0 release, our motivation, and what to expect from it. We’ve decided to name this future release Kotlin 2.0. The new frontend is already available for preview – we’re continually polishing and stabilizing it and plan to make it the default compiler frontend in a future Kotlin release. It’s also the part of the compiler that continuously runs inside your IDE, reports all error and warning messages, and helps you with tasks like auto completion, semantic-aware inspections, intentions, and refactorings. This is the part of the compiler that you, the developer, interact with the most. The frontend is the part of the compiler that parses your code and performs the semantic analysis, data flow analysis, call resolution, and type inference. We’ve been working on a new frontend for the Kotlin compiler (code-named “ K2”) for quite a while.
