"The original intent had been to call it the 5BSD release; however, there were objections from AT&T that there would be customer confusion between their commercial Unix release, System V, and a Berkeley release named 5BSD. So, to resolve the issue, Berkeley agreed to change the naming scheme for future releases to stay at 4BSD and just increment the minor number." https://www.oreilly.com/openbook/opensources/book/kirkmck.html
