I thought the official C++ standard was 2023, but according to https://isocpp.org/std/the-standard it still points to 2020. Is this just an oversight of that document? It seems to be an authoritative site.
At the time of this writing, C++23 is the current standard, and the isocpp.org website is out of date. C++23 was published October 2024 and is available from iso.org at https://www.iso.org/standard/83626.html
