Some notable features added in Visual C++ 2015 include:
The 2015 version of Visual C++ marked a significant milestone in the evolution of the compiler. With the release of Visual Studio 2015, the MSVC team focused on improving support for C++11, the C++ standard that was finalized in 2011.
Visual Studio 2019 (compiler version 19.20+) arrived with a focus on productivity, performance, and cleaning up the backlog of technical debt.

VS2017 decoupled the Windows SDK from the Visual Studio installer, allowing developers to target newer Windows APIs without upgrading the compiler toolset. Additionally, Microsoft integrated Clang/C2, allowing developers to use the Clang frontend with the MSVC CodeGen backend, aiding in cross-platform code validation.
