- Introduced Kotlin 1.0.0 with HALF_EVEN rounding as the default for BigDecimal division and an 8 KB default buffer size for IO operations.
- Updated metadata handling to use the kotlin.Metadata annotation and removed old metadata annotations, also dropping remaining deprecations.
- Fixed several critical bugs such as ProGuard inline‑function issues, generic interface resolution failures, Gradle project visibility problems, and type‑inference errors.
