It was 4BSD and 1980 according to QCU:

"In 1980 it was Bill Joy who flew to New Jersey and, together with Steve
Bourne, put 4BSD up in Bell Labs. "We did it overnight," Joy told me.
"We decided to do it about 9 p.m.; people showed up in the morning and a
new os was running. It was pretty amazing."
