What\u2019s\u00a0<\/span>New<\/span><\/h2>\n

We have<\/span>\u00a0continued our efforts to implement C++20 in the MSVC toolset, with\u00a0<\/span>noteworthy progress<\/span>\u00a0being made in<\/span>\u00a0<\/span>VS (Visual Studio)<\/span>\u00a02019 v16.7 and VS 2019 v16.8. This blog post lists the features implemented\u00a0<\/span>since<\/span> the<\/span>\u00a0<\/span>C++20 Features and Fixes in VS 2019 16.1 through 16.6<\/span><\/a> blog post.<\/span><\/p>\n

This blog post will specifically focus on language features implemented in the\u00a0<\/span>MSVC\u00a0<\/span>compiler<\/span>\u00a0(cl.exe)<\/span>. The changelog for conformance progress for the STL is tracked in the\u00a0<\/span>Standard Library changelog<\/span><\/a>\u00a0in the\u00a0<\/span>Microsoft STL GitHub<\/span><\/a>\u00a0repo<\/span>.<\/span><\/p>\n

Some of the features covered <\/span>were already highlighted in the<\/span>\u00a0announcements made\u00a0<\/span>a<\/span>t<\/span>\u00a0<\/span>CppCon<\/span>\u00a02020<\/span> in September related to the VS 2019 v16.8 Preview 3 release<\/span>.<\/span><\/p>\n

As a reminder, the\u202f<\/span>\/<\/span>std:c<\/span>++17 and \/<\/span>std:c<\/span>++latest<\/span><\/a>\u202fcompiler options are necessary to use C++17 and C++20 features<\/span>, respectively<\/span>.<\/span>\u00a0<\/span><\/p>\n
