# What's changed? ### Native Code Generation * Fixed an UAF relating to reusing a hash key after a weak table has undergone some GC. * Fixed a bounds check on arm64 to allow access to the last byte of a buffer. ### New Type Solver * Type states now preserves error-suppression, i.e. `local x: any = 5` and `x.foo` does not error. * Made error-suppression logic in subtyping more accurate. * Subtyping now knows how to reduce type families. * Fixed function call overload resolution so that the return type resolves to the correct overload. * Fixed a case where we attempted to reduce irreducible type families a few too many times, leading to duplicate errors. * Type checker needs to type check annotations in function signatures to be able to report errors relating to those annotations. * Fixed an UAF from a pointer to stack-allocated data in Subtyping's `explainReasonings`. ### Nonstrict Type Checker * Fixed a crash when calling a checked function of the form `math.abs` with an incorrect argument type. * Fixed a crash when calling a checked function with a number of arguments that did not exactly match the number of parameters required. --- ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@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> |
