- libstdc++ ABI changes (it is a significant user visible change, if you rebuild everything, no extra effort is needed, but otherwise if you want some C++ code built with older compilers work together with code built with newer compilers, it might require source code changes (the abi_tag attribute additions where needed and warning suggest to put those at), at least that is my current understanding of the plans - likely libgfortran ABI changes (different array descriptors) Jakub
