It was actually the 1.0 - 1.1 transition.  src/lib/libcrypt/crypt.c
was updated:

] revision 1.5
] date: 1995/02/19 12:19:03;  author: cgd;  state: Exp;  lines: +10 -8
] use the (broken) crypt.c from the 4.4BSD-Lite Foreign distribution, that
] can encrypt passwords but _cannot_ decrypt anything.  "real" (i.e.  two-way,
] unbroken) crypt() now lives in /usr/src/domestic.

This is the version that was used as the base for both 1.1 and 1.2
(and their respective patch releases).  If you were using the exportable
version before this, your passwords were unencrypted in /etc/master.passwd.
