On April 20, the world became aware of a
research program conducted out of the University of Minnesota (UMN) that
involved submitting intentionally buggy patches for inclusion into the

withdrawn, various
letters have gone back and forth, and numerous patches from UMN have been
audited. It’s clearly time for an update on the situation.
