## What's new This update brings improvements to the new type solver, roundtrippable AST parsing mode and closes multiple issues reported in this repository. * `require` dependency tracing for non-string requires now supports `()` groups in expressions and types as well as an ability to type annotate a value with a `typeof` of a different module path * Fixed rare misaligned memory access in Compiler/Typechecker on 32 bit platforms (Closes #1572) ## New Solver * Fixed crash/UB in subtyping of type packs (Closes #1449) * Fixed incorrect type errors when calling `debug.info` (Closes #1534 and Resolves #966) * Fixed incorrect boolean and string equality comparison result in user-defined type functions (Closes #1623) * Fixed incorrect class types being produced in user-defined type functions when multiple classes share the same name (Closes #1639) * Improved bidirectional typechecking for table literals containing elements that have not been solved yet (Closes #1641) ## Roundtrippable AST * Added source information for `AstStatTypeAlias` * Fixed an issue with `AstTypeGroup` node (added in #1643) producing invalid AST json. Contained type is now named 'inner' instead of 'type' * Fixed end location of the `do ... end` statement --- Internal Contributors: Co-authored-by: Hunter Goldstein <hgoldstein@roblox.com> Co-authored-by: Talha Pathan <tpathan@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>
