    C++20

    C++20 features are now confirmed and have been frozen. No new features now for C++20 - any new features are for C++23!

    See
    https://herbsutter.com/2019/02/23/tr...-meeting-kona/
    https://www.reddit.com/r/cpp/comment...ip_report_c20/

    C++20 will see the biggest change to the C++ language since C++11 - bigger than C++17 as it includes ranges, modules and co-routines! Now the emphasis is on producing the C++20 standard document that reflects the agreed c++ changes and features.

    The current draft C++20 standard is N4791 available at http://www.open-std.org/jtc1/sc22/wg...2018/n4791.pdf Expect subsequent draft C++20 standards to be produced until it is finalised around at the Spring 2020 meeting. Note that the drafts are free but the final standard is not and has to be bought!
