On Saturday, the ISO C++ committee completed the second-last design meeting of C++26, held in Hagenberg, Austria. There is just one meeting left before the C++26 feature set is finalized in June 2025 and draft C++26 is sent out for its international comment ballot (aka “Committee Draft” or “CD”), and C++26 is on track to be technically finalized two more meetings after that in early 2026.

see https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2024/p3471r2.html#enabling-hardening

Much like a freestanding implementation, the way to request a hardened implementation is left for the implementation to define. For example, similarly to -ffreestanding, we expect that most toolchains would provide a compiler flag like -fhardened, but other alternatives like a -D_LIBCPP_HARDENING_MODE= macro would also be conforming.

Well let's hope they don't all choose different options...
