* New `vector` library! See https://rfcs.luau.org/vector-library.html for details * Replace the use of non-portable `strnlen` with `memchr`. `strnlen` is not part of any C or C++ standard. * Introduce `lua_newuserdatataggedwithmetatable` for faster tagged userdata creation of userdata with metatables registered with `lua_setuserdatametatable` Old Solver * It used to be the case that a module's result type would unconditionally be inferred to be `any` if it imported any module that participates in any import cycle. This is now fixed. New Solver * Improve inference of `table.freeze`: We now infer read-only properties on tables after they have been frozen. * We now correctly flag cases where `string.format` is called with 0 arguments. * Fix a bug in user-defined type functions where table properties could be lost if the table had a metatable * Reset the random number seed for each evaluation of a type function * We now retry subtyping arguments if it failed due to hidden variadics. --------- Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Vighnesh <vvijay@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> Co-authored-by: Junseo Yoo <jyoo@roblox.com> |
