### What's new * Implemented parsing logic for attributes * Added `lua_setuserdatametatable` and `lua_getuserdatametatable` C API methods for a faster userdata metatable fetch compared to `luaL_getmetatable`. Note that metatable reference has to still be pinned in memory! ### New Solver * Further improvement to the assignment inference logic * Fix many bugs surrounding constraint dispatch order ### Native Codegen * Add IR lowering hooks for custom host userdata types * Add IR to create new tagged userdata objects * Remove outdated NativeState --- ### Internal Contributors Co-authored-by: Aaron Weiss 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>
