What happended to centroid?

Recently I've started to see an error from the PlaceMaker API stating:

column placemaker_woedetail.centroid does not exist

Has the API changed? This code was working fine before. And now fails on the following query:

y.execute('select woeid, name, boundingBox, centroid from geo.places where woeid in (%s)' % woeids)

This seems to have started late last week. Anyone knows why this is happening?
