 With support for generalized `constexpr` and non-static data member initialization (NSDMI) for aggregates, the Microsoft C++ compiler in Visual Studio 2017 is now complete for features added in the C++14 standard. However, the compiler still lacks a few features from the C++11 and C++98 standards. See [Visual C++ Language Conformance](../visual-cpp-language-conformance.md) for a table that shows the current state of the compiler.
