Whether Boost declares it or not I do not think Boost libraries change
the API or ABI very often between releases and, if they do, they will
notify the end-user about it. But of course you are correct that their
is no attempt at a policy that claims compatibility between releases.

So are you telling me that if I have gcc-10.2 I should be able to use
the gcc-5.1 libstdc without any ABI problems ?
