### What's New? * Fragment Autocomplete: a new API allows for type checking a small fragment of code against an existing file, significantly speeding up autocomplete performance in large files. ### New Solver * E-Graphs have landed: this is an ongoing approach to make the new type solver simplify types in a more consistent and principled manner, based on similar work (see: https://egraphs-good.github.io/). * Adds support for exporting / local user type functions (previously they were always exported). * Fixes a set of bugs in which the new solver will fail to complete inference for simple expressions with just literals and operators. ### General Updates * Requiring a path with a ".lua" or ".luau" extension will now have a bespoke error suggesting to remove said extension. * Fixes a bug in which whether two `Luau::Symbol`s are equal depends on whether the new solver is enabled. --- Internal Contributors: Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: David Cope <dcope@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>
