# What's changed? * Fix warning issued when Cmake version is too low (contributed by OSS community) ## New Solver * Fix an issue with inhabitance testing of tables with cyclic properties * Preserve error suppression during type unification * Overhaul type reference counting in the constraint solver * Other miscellaneous constraint ordering fixes ## Native Codegen * Fix incorrect assertion check in loadBytecodeTypeInfo --- ## 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: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- 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: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
