* `table.sort` was improved further. It now guarentees N*log(N) time complexity in the worst case. * Fix https://github.com/Roblox/luau/issues/880 We are also working on fixing final bugs and crashes in the new type solver. On the CodeGen front we have a few things going on: * We have a smarter register allocator for the x86 JIT * We lower more instructions on arm64 * The vector constructor builtin is now translated to IR --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
