## 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

# General

All code has been re-formatted by `clang-format`; this is not
mechanically enforced, so Luau may go out-of-sync over the course of the
year.

# New Solver

* Track free types interior to a block of code on `Scope`, which should
reduce the number of free types that remain un-generalized after type
checking is complete (e.g.: less errors like `'a <: number is
incompatible with number`).

# Autocomplete

* Fragment autocomplete now does *not* provide suggestions within
comments (matching non-fragment autocomplete behavior).
* Autocomplete now respects iteration and recursion limits (some hangs
will now early exit with a "unification too complex error," some crashes
will now become internal complier exceptions).

# Runtime

* Add a limit to how many Luau codegen slot nodes addresses can be in
use at the same time (fixes #1605, fixes #1558).
* Added constant folding for vector arithmetic (fixes #1553).
* Added support for `buffer.readbits` and `buffer.writebits` (see:
https://github.com/luau-lang/rfcs/pull/18).

### 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.
