Update on MSVC’s implementation of the C++20 Standard Library
summary
MSVC’s C++ Standard Library lives at github.com/Microsoft/STL and is now built with CMake build scripts and Azure Pipelines CI; tests and the change log are open so fixes land faster. Already shipped community PRs appear in VS 2019 updates 16.5–16.6 (span, ranges algorithms, contains, starts_with/ends_with, char8_t support, from_chars/to_chars, heterogeneous lookup, erase‑remove helpers, constexpr improvements). The repo reports 32 features remaining (~30% of C++20 library) and uses Apache-2.0 with LLVM exception to permit broad binary redistribution.
