My impression is the opposite. Boost has never declared backward ABI or 
API compatibility. There's a reason why binary distributions of Boost 
append a version tag that matches Boost version to packages and binaries.

You have to give credit to libstdc++ developers at the very least. It 
maintains backward ABI compatibility across all C++ standard versions 
and across libstdc++ releases for many years. I think, libc++ also does 
the same, although I'm not following its development.
