-## <a name="improvements_178"></a> Conformance improvements in Visual Studio 2022 version 17.8
-
-Visual Studio 2022 version 17.8 contains the following conformance improvements, bug fixes, and behavior changes in the Microsoft C/C++ compiler.
-
-### /FU issues an error
-
-The C compiler used to accept the `/FU` option, even though it hasn't support managed compilation for some time. It now issues an error. Projects that pass this option need to restrict it to C++/CLI projects only.
-
-### C++ Standard Library
-
-The C++23 named modules `std` and `std.compat` are now available when compiling with `/std:c++20`.
-
-For a broader summary of changes made to the C++ Standard Library, see [STL Changelog VS 2022 17.8](https://github.com/microsoft/STL/wiki/Changelog#vs-2022-178-preview-3).

-## <a name="improvements_177"></a> Conformance improvements in Visual Studio 2022 version 17.7
-
-Visual Studio 2022 version 17.7 contains the following highlighted conformance improvements, bug fixes, and behavior changes in the Microsoft C/C++ compiler.
-
-### Added `/std:clatest` to the C compiler
-
-This switch behaves like the `/std:c++latest` switch for the C++ compiler. The switch enables all currently implemented compiler and standard library features proposed for the next draft C standard, as well as some in-progress and experimental features.
-
-### C++ Standard Library
-
-The `<print>` library is now supported. See [P2093R14 Formatted output](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p2093r14.html).
-
-Implemented `views::cartesian_product`.
-
-For a broader summary of changes made to the Standard Template Library, see [STL Changelog VS 2022 17.7](https://github.com/microsoft/STL/wiki/Changelog#vs-2022-177).
-
-### `using` conformance
-
-Previously, the `using` directive could cause names from used namespaces to remain visible when they shouldn't. This could cause unqualified name lookup to find a name in a namespace even when there's no `using` directive active.
-
-Here are some examples of the new and old behavior.\
-References in the following comments to "(1)" mean the call to `f<K>(t)` in namespace `A`:
-
-```cpp
-namespace A
-{ 
-    template<typename K, typename T> 
-    auto f2(T t)
-    { 
-        return f<K>(t); // (1) Unqualified lookup should not find anything
-    } 
-} 
-
-namespace B
-{ 
-    template<typename K, typename T> 
-    auto f(T t) noexcept
-    { // Previous behavior: This function was erroneously found during unqualified lookup at (1)
-        return A::f2<K>(t); 
-    } 
-} 
-
-namespace C
-{ 
-    template<typename T> 
-    struct S {}; 
-
-    template<typename, typename U> 
-    U&& f(U&&) noexcept; // New behavior: ADL at (1) correctly finds this function 
-} 
-
-namespace D
-{ 
-    using namespace B; 
-
-    void h()
-    { 
-        D::f<void>(C::S<int>()); 
-    } 
-} 
-```
-
-The same underlying issue can cause code that previously compiled to now be rejected:
-
-```cpp
-#include <memory>
-namespace Addin {}
-namespace Gui
-{
-    using namespace Addin;
-}
-
-namespace Addin
-{
-    using namespace std;
-}
-
-// This previously compiled, but now emits error C2065 for undeclared name 'allocator'.
-// This should be declared as 'std::allocator<T*>' because the using directive nominating
-// 'std' is not active at this point.
-template <class T, class U = allocator<T*>>
-class resource_list
-{
-};
-
-namespace Gui
-{
-    typedef resource_list<int> intlist;
-}
-```
