It's not normal in FreeBSD.  Library versions are only changed when
there is an incompatible change that means the new library *CANNOT* be
used with certain old binaries.  While you may be able to sometimes
get away with running certain applications (or certain parts of
applications) that do not interact with the incompatible changes, it
is never a safe thing to do.
