MSVC C++20/23 Update
summary
MSVC updates C++20 defect reports into ABI-stable mode and ships multiple C++23 library features: VS 2022 17.2 moves ranges/format to std C++20, and backports key fixes to VS 2019 16.11. Compiler adds arbitrary requires expressions and deducing this. Library adds std::string::contains, deleted nullptr constructors for string/string_view, resize_and_overwrite for efficient C-API fills, move_only_function, and monadic optional ops; live Godbolt examples compile and run, and several real-world breaks are fixed by the stricter checks.
