## What's new * Added `math.map` function to the standard library, based on https://rfcs.luau-lang.org/function-math-map.html * `FileResolver` can provide an implementation of `getRequireSuggestions` to provide auto-complete suggestions for require-by-string ## New Solver * In user-defined type functions, `readproperty` and `writeproperty` will return `nil` instead of erroring if property is not found * Fixed incorrect scope of variadic arguments in the data-flow graph * Fixed multiple assertion failures --- Internal Contributors: Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@roblox.com> Co-authored-by: Varun Saini <vsaini@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
