Welcome to the Kotlin roadmap! Get a sneak peek into the priorities of the Kotlin Team.
The goal of this roadmap is to give you a big picture. Here’s a list of our key priorities – the areas we are investing the most effort into:
Fast turnaround: making the change-test-debug cycle really fast.
New compiler: a rewrite of the Kotlin compiler optimized for speed, parallelism, and unification. Later we will also work on pluggability.
Fast and smooth IDE: improving the stability and performance of the Kotlin IDE.
Kotlin for JVM server-side development: expanding support for server-side use cases across the Kotlin ecosystem.
Kotlin Multiplatform Mobile: improving the user experience and feature set for sharing code on mobile platforms.
