March 2026 — Documentation cleanup for Kotlin Multiplatform Dev Docs. Removed outdated kotlin.publishJvmEnvironmentAttribute references to align with Kotlin 2.0.0, preventing confusion about deprecated features. Change implemented via commit d1b95d5da66f01f272c890352855aa644d1e98dd, addressing issue #604.

January 2026: Delivered critical build-system modernization and licensing compliance improvements across swift-java and CI workflows, strengthening build reliability, maintainability, and licensing governance. Key changes include migrating Gradle scripts from Groovy to Kotlin DSL for faster onboarding and fewer configuration errors, hardening jextract path handling to ensure only intended Java sources are compiled and to prevent runtime/build-time failures, expanding licensing metadata coverage to Kotlin sources and version catalogs, and enhancing license enforcement by extending checks to Kotlin and TOML sources in Gradle scripts. These efforts reduce build risk, improve developer velocity, and reinforce compliance across the codebase and CI pipelines.

February 2025 – Kotlin/kotlinx.coroutines: Build system simplification and API deprecation readiness. Removed split JVM source sets (jvmCoreMain and jdk8Main) and their associated compilations to streamline the core build, and aligned the project with KotlinCompilation.source API deprecation. This reduces configuration complexity, shortens CI cycles, and establishes a clear migration path for API changes, delivering measurable long-term maintainability and speed improvements.
