### What's Changed - Improve readability of unions and intersections by limiting the number of elements of those types that can be presented on a single line (gated under `FFlag::LuauToStringSimpleCompositeTypesSingleLine`) - Adds a new option to the compiler `--record-stats` to record and output compilation statistics - `if...then...else` expressions are now optimized into `AND/OR` form when possible. ### VM - Add a new `buffer` type to Luau based on the [buffer RFC](https://github.com/Roblox/luau/pull/739) and additional C API functions to work with it; this release does not include the library. - Internal C API to work with string buffers has been updated to align with Lua version more closely ### Native Codegen - Added support for new X64 instruction (rev) and new A64 instruction (bswap) in the assembler - Simplified the way numerical loop condition is translated to IR ### New Type Solver - Operator inference now handled by type families - Created a new system called `Type Paths` to explain why subtyping tests fail in order to improve the quality of error messages. - Systematic changes to implement Data Flow analysis in the new solver (`Breadcrumb` removed and replaced with `RefinementKey`) --- 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: Lily Brown <lbrown@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com>
