Ah, good point.  Yes, that seems to suggest that whenever a soname bump
is done, you can no longer use the old version symbols.  That was rather
non-obvious to me.

Maybe a tutorial on "shared library versioning for maintainers" howto
would be useful, I don't think Uri's documentation is well suited for
that purpose.
