# What's Changed? - Fix #1137 by appropriately retaining additional metadata from definition files throughout the type system. - Improve Frontend for LSPs by appropriately allowing the cancellation of typechecking while running its destructor. ## New Solver - Added support for the `rawget` type function. - Reduced overall static memory usage of builtin type functions. - Fixed a crash where visitors could mutate a union or intersection type and fail to invalidate iteration over them in doing so. - Revised autocomplete functionality to not rely on a separate run of the type solver when using the new solver. - Implemented a more relaxed semantic rule for casting. - Fixed some smaller crashes in the new solver. ## Native Code Generation - Add additional codegen specialization for `math.sign` - Cleaned up a large number of outstanding fflags in the code. ### 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: Jeremy Yoo <jyoo@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>
