Chuck Walbourn -

Visual Studio 2019 Update 8 (a.k.a. 16.8) is now available for download. For more information see the Visual Studio Team blog.

The latest VS 2019 Redistribution packages are available (x86, x64, ARM64), as well as the Remote Debugging Tools (x86, x64, ARM64). For more on Visual Studio 2019 Update 8, see the release notes.

Compiler and CRT

VS 2019 Update 8 includes a new version of the C/C++ compiler (19.28.29333.0).

16.8 update C++ compiler
16.8.0 19.28.29333.0
16.8.2 19.28.29334.0
16.8.3 19.28.29335.0
16.8.4 19.28.29336.0
16.8.5 19.28.29337.0

A full list of updates to the Standard C++ Library can be found on GitHub.

The C/C++ Runtime (14.28.29325) is included in this update. Remember that VS 2015, VS 2017, and VS 2019 share the same runtime redistributable binaries and are binary compatible.

C++20: This release includes more work on C++20 conformance enabled when building with /std:c++latest. This includes coroutines, modules, and other compiler features.

C11/C17: Visual C++ as of 16.8 supports the required portions of ISO C11 and C17, introducing /std:c11 and /std:c17 conformance switches. See this blog post for more details and limitations.

ISO C99 is not supported by Visual C++

Cmake: This release includes CMake 3.18 integration. See release notes for a full list of changes.

clang/LLVM: The clangcl <PlatformToolset> for using clang for Windows with MSBuild now supports ARM64, in addition to x64/x86. This builds using clang v10 w/ --target=arm64-pc-windows-msvc.

/analyze: There are some new safety rules for Static Code Analysis /analyze in this release.

DirectXMath: There is a known issue where the IsNan tests can fail when building with /fp:fast due to new optimizations. This is fixed when using DirectXMath 3.14 which is in Windows 10 SDK (19041) in combination with this update.
