This is news? It sounds like standard lexicographic practice to me. If it is newsworthy, I can think of many other fascinating stories:
“Social Security Administration Stops Sending Checks to People Who Died Last Month”
“New Edition of Biology Text Has the Latest Science”
“Video Store Sells Excess Copies of Last Year’s Releases”
(Although I did get a kick out of seeing the word agrestic on the list; it is the name of the cookie-cutter, Southern California town in the TV show Weeds. I had always assumed the writers made the name up; it sounds like something a marketing department would come up with.)
