(V7) The unsupported release of UniX ancestral to all current commercial versions. {Brian Kernighan} announced the release of V7 in summer 1979, at the UniX User' s Group meeting in Toronto. Before the release of the POSIX/SVIDstandards, V7' s features were often treated as a UniX portability baseline. Some old-timers impatient with commercialisation and {kernel bloat} still maintain that V7 was the Last True UniX. See BSD, USG UniX, System V. [Jargon File] (1996-05-22)
