If by "UNIX v5" you mean 5th Edition UNIX then obviously it's not the
same as USG UNIX 5.0 which was produced about 10 years later.  By the
way, (formerly) USG UNIX 6.0 turned into UNIX System V Release 2 by
the time it reached the public.

The Don Speck summary was fairly accurate.  The exact effects of
different UNIX variants on each other are hard to untangle, although
for the most part significant new features originate in the research
versions, as one would expect.  But the AT&T UNIX Development guys at
Summit and elsewhere have come up with numerous contributions too.

Why do we care, anyway?
