* General - Fix the benchmark require wrapper function to work in Lua - Fix memory leak in the new Luau C API test * New Solver - Luau: type functions should be able to signal whether or not irreducibility is due to an error - Do not generate extra expansion constraint for uninvoked user-defined type functions - Print in a user-defined type function should be reported as an error instead of logging to stdout - Many e-graphs bugfixes and performance improvements - Many general bugfixes and improvements to the new solver as a whole - Fixed issue with Luau used-defined type functions not having all environments initialized - Infer types of globals under new type solver * Fragment Autocomplete - Miscellaneous fixes to make interop with the old solver better * Runtime - Support disabling specific Luau built-in functions from being fast-called or constant-evaluated - Added constant folding for vector arithmetic - Added constant propagation and type inference for Vector3 globals ---------------------------------------------------------- 9 contributors: Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: Daniel Angel <danielangel@roblox.com> Co-authored-by: Jonathan Kelaty <jkelaty@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@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>
