Anyone out there are using the Component_changes.il, I tried to use it and it didn't work. I looked inside the file and its was written by Peter to work with Allegro 11 and later got modied to work with 14.2 by Ron Guthrie. Cadence Design Systems.
I am using ver 16.6
It would be nice to compare 2 xxx.brd files to see what have changed since the previous versions.
