# What's Changed?
We've been hard at work fixing bugs in the new type solver and getting
it ready to go!
## Native Codegen
* Specialized Luau Codegen instruction for fetching an import.
As a reminder, an import is an expression like `global.thing` and covers
stuff like libraries without fastcalls `coroutine.resume`) and atomic
extern libraries.
## New Type Solver
* Fix an issue that prevented eager generalization from working properly
with OO styled code.
* Avoid copying uninitialized memory in Luau attribute parsing
* Improve type inference of unsealed tables.
* This fixes https://github.com/luau-lang/luau/issues/1838
* and https://github.com/luau-lang/luau/issues/1859
* Infer potential singleton string keys in autocomplete when the
expected index type is a union type.
* Avoid creating cyclic types when reducing types of the form `t1 where
t1 = refine<T, t1, Y>`
* The type cloner now does the same thing for the new and old solvers.
* Properly infer polarity (aka variance) for divergent table properties.
(ie tables whose read type and write type are not the same)
* Crash fixes.
