### What's new * Fixed many of the false positive errors in indexing of table unions and table intersections * It is now possible to run custom checks over Luau AST during typechecking by setting `customModuleCheck` in `FrontendOptions` * Fixed codegen issue on arm, where number->vector cast could corrupt that number value for the next time it's read ### New Solver * `error` type now behaves as the bottom type during subtyping checks * Fixed the scope that is used in subtyping with generic types * Fixed `astOriginalCallTypes` table often used by LSP to match the old solver --- ### 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>
