I thought it was: major version increments when any existing interface
is changed _incompatibly_, such that programs that expect the old
interface won't work with the new interface.  Minor version increments
for all other changes.

Thus, adding new calls would be a minor-version change.  Changing the
semantics of an existing call would be a major-version change.
Depending on how strongly you feel about the subject (and whether you
object to having minor numbers up in the hundreds or thousands :-),
bugfixes could be minor-version changes or could result in no version
number changes.
