It has been suggested before that the last update to a version of
Stata should include the ability to read/convert files from the new
version. StataCorps has replied by saying this is much more difficult
than it sounds. But, if this is the extent of the changes, maybe it
can be done in this case. Lack of file compatibility across versions
is a pain, especially when the gains from a new format seem pretty minor.
