We have lots of new changes for you! # What's Changed ## General - We updated Luau's license year to 2025! - We fixed a bug where large amounts of errors were being printed when deep intersections of unions error. ## Require-by-String This release introduces the `Luau.Require` library, which exposes the runtime semantics of require-by-string, including support for the new `@self` alias described in [this RFC](https://github.com/luau-lang/rfcs/pull/109). The library operates on a virtualized filesystem, allowing consumers to specify navigation rules without assuming a filesystem context. Documentation in `Require.h` explains how to enable the library, and the `setupState` function in Repl.cpp demonstrates how we've integrated it into the luau CLI tool. Note that the interface in `Require.h` is written in C, which enables any application written in a language with a C foreign-function interface to link against this library and enable require-by-string. This makes it straightforward for any application embedding Luau to support require-by-string, provided that it defines or operates within an environment resembling a virtual filesystem. The core navigation semantics of require-by-string have additionally been pulled into the `Luau.RequireNavigator` library. While `Luau.Require` internally depends on `Luau.RequireNavigator`, the latter does not depend on the Luau VM. This library provides an interface for inspecting require-by-string's navigation behavior and therefore serves as a useful dependency for static tooling. Documentation for `Luau.RequireNavigator` is available in `RequireNavigator.h`. ## Autocomplete - We fixed a memory leak in fragment autocomplete! ## New Solver And Old Solver - We've found a infinite iteration error over a type pack. We added a way to detect this error and throw an `InternalCompileError` instead. - We fix `table.freeze` not accounting for the first argument not getting type stated. We fall back to regular inference instead. - We fix a crash in the old solver with `length_error`. - We fix a crash in the new solver stemming from generalization reentrancy. Now we correctly generalize interior free types that do not appear in a function signature. - We fix a nil refinement.
