I am not sure you can make that conclusion, as the 4.0 printed documents
did not include the programmer's manual; instead they gave out the
3.0 manual and there was a list of changes somewhere in the other doc.

Unfortunately, without actual 4.0 sources, it will always be a question.

I have this VERY vague memory that I saw IPC in 4.0, but I could
very easily be wrong... It was over 40 years ago, after all. :-)
