* Type mismatch errors now mention if unification failed in covariant or invariant context, to explain why sometimes derived class can't be converted to base class or why `T` can't be converted into `T?` and so on * Class type indexing is no longer an error in non-strict mode (still an error in strict mode) * Fixed cyclic type packs not being displayed in the type * Added an error when unrelated types are compared with `==`/`~=` * Fixed false positive errors involving sub-type tests an `never` type * Fixed miscompilation of multiple assignment statements (Fixes https://github.com/Roblox/luau/issues/754) * Type inference stability improvements
