| To anyone who uses the List.pm macros:
We recently discovered a minor bug in the way the condense method in
List.pm eliminated duplicate answers. Essentially, there was a list of
answers, some of which may be duplicates. The code just ran through the
list and deleted duplicates but it didn't double check that same place
in the list (since the old value was deleted, there would be a new
value in that place in the list), and so if there was another duplicate
immediately after the one that was deleted, that duplicate would not be
checked and so the answers would still have a duplicate answer.
This has been updated to system on both webwork and webwork2 so the
problem should be eliminated, but if you come up with new errors or if
you want this updated version of List.pm, please email me at webwork_interns@math.rochester.edu.
