# General Updates
* Fix some cases where documentation symbols would not be available when
mouseovering at certain positions in the code
* Scaffolding to help embedders have more control over how `typeof(x)`
refines types
* Refinements to require-by-string semantics. See
https://github.com/luau-lang/rfcs/pull/56 for details.
* Fix for https://github.com/luau-lang/luau/issues/1405
# New Solver
* Fix many crashes (thanks you for your bug reports!)
* Type functions can now call each other
* Type functions all evaluate in a single VM. This should improve
typechecking performance and reduce memory use.
* `export type function` is now forbidden and fails with a clear error
message
* Type functions that access locals in the surrounding environment are
now properly a parse error
* You can now use `:setindexer(types.never, types.never)` to delete an
indexer from a table type.
