- Added new compiler capabilities such as default values for expect/actual annotation constructors, crossinline suspend lambdas, default arguments for expected declarations, @JvmDefault annotation, and warnings for outdated stdlib artifacts.
- Improved performance and code generation, including use of lcmp instruction, optimized for‑loop with withIndex, reduced memory footprint of KotlinBinaryClassCache, and IDE speed gains for Spring projects.
- Fixed a wide range of bugs across compiler, IDE, Gradle/KTS handling, inspections and refactorings, addressing incorrect bytecode, warning messages, SAM conversion issues, and crashes in intentions and quick‑fixes.
