Incorrect documentation for changes-check goal -- references "release phase"

The documentation for the changes-check goal [1] mentions attaching the goal to the "release phase". According to all the maven lifecycle documentation I've been able to dig up, I can't find any mention of a "release phase". I also found a question over on stackoverflow about a "release phase" and the answer was that it did not exist. Is this an error in the documentation of the plugin that needs corrected?
