A Look Into the Future
summary
Kotlin 1.4 emphasizes quality and performance and continues work on Kotlin Multiplatform Mobile to share code between Android and iOS; JVM interoperability targets Records and Sealed Classes so Java APIs (and Project Loom) work out of the box. Community tracking uses YouTrack and KEEP; callable-reference changes had ~70 votes and function interfaces (200 votes) lands as a solved SAM problem in 1.4. Proposals like a ternary operator (80 votes) are declined; ideas under exploration include namespace extensions, decorators, value‑based classes to replace inline class naming ahead of Java Valhalla, and compiler plugins (e.g. Jetpack Compose @Composable, differentiable programming).
