Welcome to the Kotlin roadmap! Get a sneak peek into the priorities of the JetBrains Team.
Key priorities
The goal of this roadmap is to give you the big picture. Here's a list of our key focus areas – the most important directions we are focused on delivering:
Language evolution: keep Kotlin both pragmatic and expressive with meaningful language improvements that emphasize semantics over syntax changes.
Multiplatform: build the foundation for modern multiplatform apps with solid iOS support, mature web targets, and reliable IDE tooling.
Staying agnostic: support developers no matter their tools or targets.
Ecosystem support: simplify the development and publication process for Kotlin libraries, tools, and frameworks.
