As such, C++ programs that used standard library components without including the right headers will no longer compile. The following headers are used less widely in libstdc++ and may need to be included explicitly when compiled with GCC 11: <limits> (for std::numeric_limits) <memory> (for std::unique_ptr, std::shared_ptr etc.) <utility> (for std::pair, std::tuple_size, std::index_sequence etc.) <thread> (for members of namespace std::this_thread.)
