- Introduced new Analysis API features such as klib content reading, virtual file inputs, type annotation support, KtCodeFragment handling, concurrent session invalidation, and multi‑threaded resolve.
- Implemented performance and memory optimizations, reducing redundant resolutions, improving getFirForNonKtFileElement, enhancing lazy resolve behavior, and adding parallel resolve capabilities.
- Fixed numerous bugs and crashes across the Analysis API, K2 IDE, code generation, and scripting, including ClassCastExceptions, unresolved calls, incorrect symbol overrides, KtCodeFragment.clone issues, and annotation handling errors.
