### What's new? * Removed new `table.move` optimization because of correctness problems. ### New Type Solver * Improved error messages for type families to describe what's wrong in more detail, and ideally without using the term `type family` at all. * Change `boolean` and `string` singletons in type checking to report errors to the user when they've gotten an impossible type (indicating a type error from their context). * Split debugging flags for type family reduction (`DebugLuauLogTypeFamilies`) from general solver logging (`DebugLuauLogSolver`). * Improve type simplification to support patterns like `(number | string) | (string | number)` becoming `number | string`. ### Native Code Generation * Use templated `luaV_doarith` to speedup vector operation fallbacks. * Various small changes to better support arm64 on Windows. ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: James McNellis <jmcnellis@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>
