Kotlin/Wasm Tail Calls and the Kotlin Education Map

GSoC 2026 resulted in tail call support for Kotlin/Wasm and a structured database for tracking Kotlin’s spread in education.

Executive summary

I read that the Kotlin Foundation is once again participating in GSoC 2026, with two completed projects: adding tail call support to the Kotlin/Wasm backend and mapping Kotlin usage in education globally. This is important for engineers because it touches the WebAssembly runtime while also providing a data source that can be used to understand the reach of Kotlin in education.
