- Fixed a wide range of compiler diagnostic and code generation bugs, including type inference errors, overload resolution ambiguities, verification errors, and incorrect nullability warnings.
- Added and refined IDE features such as new inspections (e.g., leaking‑this), numerous quick‑fixes and intentions, improved KDoc rendering, and updated documentation formatting.
- Implemented performance and bytecode optimizations in the standard library and JVM backend, like optimized for‑loops over ranges and reduced redundant bridge methods.
