To be honest I have not read ed. 4 and 5 from cover to cover but e.g. I noticed that 2-J-3 changed: 4th Ed. has short A-D items, the 5th dropped the Aiming Point delivery line, and 6th went to two very long paragraphs A and B.
Thank you!

I dont know about the 21 st . Id just love to see every page of Yoda marked up 6th personal edition. Golf Hall of Fame worthy IMO. But it probably wont happen.
I believe that a discussion of Homer Kelley's Concepts will be very beneficial. I have all seven editions. If anyone wants to see the changes in certain items, I am happy to provide.
