# What's Changed?
This week includes many changes to bring the behaviours of the Old and
New Luau Type Solver more in line.
* The old solver now stringifies tables identically to the new solver.
Sealed tables are stringified as `{ ... }` and unsealed tables are
represented by `{| ... |}`, regardless of your choice of solver.
## New Type Solver
* Miscellaneous fixes to make the Luau Frontend able to dynamically
toggle which solve is used.
* Small fixes to reduce instances of nondeterminism of the New Type
Solver.
* Issue an error when a function that has multiple non-viable overloads
is used.
* Subtyping now returns more information about the generics for type
inference to consume.
* Stop stuck type-functions from blocking type inference. This should
lead to fewer instances of 'type inference failed to complete'.
## Fragment Autocomplete
* Fixed a bug where incremental autocomplete wouldn't be able to provide
results directly on a required module script.
`require(script.Module).{request completions here}` will now recommend
the properties returned by the required object.
