 ==================
 
-Current releases are broken
----------------------------
-Due to Visual Studio removing std::format from C++20, and cmake changing the compiler flag for C++20
-ttauri releases will be broken until Visual Studio 2022 is officially released. After
-Visual Studio 2022 we should be able to make c++23 builds which should work for some time.
-However in the future it will break again due to ABI changes of std::format.
+Currently VCPKG builds are not recommended
+------------------------------------------
+
+Due to future changes to the C++20 standard involving ABI changes in
+std::format and std::ranges there are some issues with compatibility
+between compiler and cmake versions. Please use the non-vcpkg builds
+which ensures that cmake and compiler versions are exactly the same.
