# General This week has been focused primarily on bugfixes, with a ton of usability improvements to the new solver, fragment autocomplete, and the concrete syntax tree project. ## Runtime - Fix an assertion caused by failing to allocate native code pages. - Expose a `lua_pushrequire` function, which performs the same initialization steps as `luaopen_require` but does not register require globally. This lets users create specialized, custom `requires`. # New Solver - Fix a bug in simplification of types caused by combinatorial explosion of intersection and union types. - Fix a memory leak in fragment autocomplete - Improve the isolation of modules in fragment autocomplete - Throw errors when users define a type function with the name `typeof` - Continue to narrow intersection types which might be `never`. - Major rework of generalization continues - we are blazing a new path with eager + non-reentrant generalization and actively working to make these more performant and less error prone. - Improve the ability of `and/or` type functions to reduce, even when their arguments are generic. - Report arity mismatches for undersaturated calls with unknown parameters # New Non-Strict - Extends the new non-strict mode to report unknown symbols in types # Old Solver - Fix a crash caused by excessive stack usage during typechecking # Misc - Improvements to Concrete Syntax Tree location tracking for string table props. --- Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Ariel Weiss <aaronweiss@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@roblox.com> Co-authored-by: Sora Kanosue <skanosue@roblox.com> Co-authored-by: Talha Pathan <tpathan@roblox.com> Co-authored-by: Varun Saini <vsaini@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> |
