# What's Changed ## New Type Solver - Many fixes to crashes, assertions, and hangs - Binary type family aliases now have a default parameter - Added a debug check for unsolved types escaping the constraint solver - Overloaded functions are no longer inferred - Unification creates additional subtyping constraints for blocked types - Attempt to guess the result type for type families that are too large to resolve timely ## Native Code Generation - Fixed `IrCmd::CHECK_TRUTHY` lowering in a specific case - Detailed compilation errors are now supported - More work on the new allocator --- # 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: James McNellis <jmcnellis@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com>
