- Added coroutine intrinsic `suspendCoroutineUninterceptedOrReturn` and several compiler optimizations (e.g., for‑loop withIndex, better tail‑suspend detection, language version settings cache).
- Enhanced the IDE with new inspections, intentions, quick‑fixes, refactoring support, TestNG support for kotlin.test, and the Android Gradle plugin `org.jetbrains.kotlin.platform.android`.
- Fixed numerous compiler and IDE crashes, incorrect warnings, navigation and formatting issues, and other bugs across Android extensions, serialization, and multimodule projects.
