Mar 1, 2026March 2026: Focused work on Haxe null-safety semantics in generic contexts. Implemented normalization of Null<T> to Dynamic for generic type parameters, ensuring consistent null-safety semantics and safer generics usage. Delivered a test suite to validate the behavior under null safety, strengthening API contracts and reducing risk of runtime null dereferences. Prepared groundwork for broader null-safety adoption across the repository.

Feb 1, 2026In February 2026, delivered a focused feature to strengthen Haxe constructor reliability and developer experience. Implemented enhanced diagnostics for constructor calls by detecting missing fields, providing precise error messages, and adding tests to verify the new diagnostics, significantly reducing debugging time and improving the robustness of the Haxe type system. This aligns with core maintenance objectives and reduces time-to-fix for constructor-related issues in downstream projects.
