The online OED has just published another quarterly update, revising the entries from quittal to ramvert. New words added to the dictionary include subprime, adj.; wantaway, adj.; cookie cutter, n. & adj.; and radiophysics, n.¹; this last referring to branch of physics dealing with ionizing radiation; the original entry, which is now radiophysics, n.², refers to the physics of radio waves.

Editor John Simpson comments on the changes here.
