> 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 (e.g.: https://egraphs-good.github.io/). * Adds support for exported / local user type functions. * Fixes a set of bugs in which the new solver will fail to complete inference for simple expressions with just literals and operators. > General * It is now an explicit runtime error to `require` a path with a ".lua" or ".luau" extension, and the error message will suggest removing the extension. ``` require("path/to/mymodule.lua") ``` * Fixes a bug in which whether two `Symbol`s are equal depends on whether the new solver is enabled.
