Welcome to the Kotlin roadmap! Get a sneak peek into the priorities of the Kotlin Team.
Key priorities
The goal of this roadmap is to give you a big picture. Here's a list of our key projects – the most important things we focus on delivering:
K2 compiler: a rewrite of the Kotlin compiler optimized for speed, parallelism, and unification. It will also let us introduce many anticipated language features.
K2-based IntelliJ plugin: much faster code completion, highlighting, and search, together with more stable code analysis.
Kotlin Multiplatform: promote the technology to Stable by improving the toolchain stability and documentation, and ensuring compatibility guarantees.
Experience of library authors: a set of documentation and tools helping to set up, develop, and publish Kotlin libraries.
