Upgrading can cause the user some unneeded work.
E.g. the next stable release of Debian will likely ship with 2.3.1 .
So in this specific case fulfilling a 2.3.1 requirement would be easy,
while a 2.3.2 requirement would make it much harder to build gcc 4.4 .
And upgrading from 2.3.1 to let's say 3.0.0 might be a bad choice if
the new version contains regressions.
