As always, a weekly Luau update! This week we have further improvements to new type solver, fixing a few of the popular issues reported. The fragment autocomplete is even more stable and we believe it's ready for broader use. Aside from that we have a few general fixes/improvements: * Fixed data race when multi-threaded typechecking is used, appearing as a random crash at the end of typechecking * AST data is now available from `Luau::Module` ## New Type Solver * Fixed type refinements made by function calls which could attach `nil` as an option of a type before (Fixes #1528) * Improved bidirectional typechecking in tables (Fixes #1596) * Fixed normalization of negated types * `getmetatable()` on `any` type should no longer report an error ## Fragment Autocomplete * Fixed auto-complete suggestions being provided inside multiline comments * Fixed an assertion failure that could happen when old type solver was used * Fixed issues with missing suggestions when multiple statements are on the same line * Fixed memory safety issues ## Internal Contributors Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
