### What's new * Added lint warning for using redundant `@native` attributes on functions inside a `--!native` module * Improved typechecking speed in old solver for modules with large types ### New Solver * Fixed the length type function sealing the table prematurely * Fixed crashes caused by general table indexing expressions ### VM * Added support for a specialized 3-argument fast-call instruction to improve performance of `vector` constructor, `buffer` writes and a few `bit32` methods --- ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- 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: 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>
