Only if the changes make it possible for a program linked against the
patched version of the library to fail if run against the unpatched
version - e.g., if a new routine is added to the library.  The minor
version number is to be bumped whenever an upward-compatible but not
downward-compatible (or maybe it's the other way around) change is made,
and the major version number is to be bumped when an incompatible change
is made.
