# What's changed? * Improved the actual message for the type errors for `cannot call non-function` when attempting to call a union of functions/callable tables. The error now correctly explains the issue is an inability to determine the return type of the call in this situation. * Resolve an issue where tables and metatables were not correctly being cloned during instantiation (fixes #1176). * Refactor `luaM_getnextgcopage` to `luaM_getnextpage` (generally removing `gco` prefix where appropriate). * Optimize `table.move` between tables for large ranges of elements. * Reformat a bunch of code automatically using `clang-format`. ### New Type Solver * Clean up minimally-used or unused constraints in the constraint solver (`InstantiationConstraint`, `SetOpConstraint`, `SingletonOrTopTypeConstraint`). * Add a builtin `singleton` type family to replace `SingletonOrTopTypeConstraint` when inferring refinements. * Fixed a crash involving type path reasoning by recording when type family reduction has taken place in the path. * Improved constraint ordering by blocking on unreduced types families that are not yet proven uninhabitable. * Improved the handling of `SetIndexerConstraints` for both better inference quality and to resolve crashes. * Fix a crash when normalizing cyclic unions of intersections. * Fix a crash when normalizing an intersection with the negation of `unknown`. * Fix a number of crashes caused by missing `follow` calls on `TypeId`s. * Changed type family reduction to correctly use a semantic notion of uninhabited types, rather than checking for `never` types specifically. * Refactor the `union` and `intersect` type families to be variadic. ### Native Code Generation * Improve translation for userdata key get/set and userdata/vector namecall. * Provide `[top level]` and `[anonymous]` as function names to `FunctionStats` as appropriate when no function name is available. * Disable unwind support on Android platforms since it is unsupported. * --- ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Alexander McCord <amccord@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>
