- New compiler and IDE features – typeOf support, script‑to‑JAR saving, external nullability annotations, copy‑diagnostics action, and a new type‑inference engine enabled in the IDE.
- Fixed a wide range of bugs, including Android DataBinding errors, coroutine and suspend‑lambda LVT issues, import handling glitches, contract and inference crashes, and numerous IDE reference and memory‑leak problems.
- Performance gains such as faster trimIndent/trimMargin, lazy parsing of classes/functions, quicker import optimization, and reduced UI freezes on project open.
