Nothing, according to the article: The AP sent the NSF a detailed list of questions about its investigation in early June and has continued to correspond since, including asking for any planned changes to address sexual harassment and assault. The NSF never listed any planned changes to alcohol policies. “Because these changes are related to morale and welfare and not sexual assault/harassment prevention, we did not mention this program initiative in our previous response,” the NSF said in a statement.
