### What's new * Light update this week, mostly fast flag cleanups. ### New Solver * Rename flag to enable new solver from `DebugLuauDeferredConstraintResolution` to `LuauSolverV2` * Added support for magic functions for the new type checker (as opposed to the type inference component) * Improved handling of `string.format` with magic function improvements * Cleaning up some of the reported errors by the new type checker * Minor refactoring of `TypeChecker2.cpp` that happens to make the diff very hard to read. --- ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@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: 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> Co-authored-by: Junseo Yoo <jyoo@roblox.com>
