> 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. |

Luau
Luau is a fast, small, safe and gradually typed embeddable scripting language derived from Lua. It is used by Roblox game developers to write game code, as well as by Roblox engineers to implement large parts of the user-facing application code as well as portions of the editor (Roblox Studio) as plugins.
This repository hosts documentation for the language as well as satellite materials.
