There have been several changes to 8r.enc in the past. Walter took
over the maintenance (the file is now part of psnfss) at a time where
different versions have been floating around.

Have a look at
  CTAN:macros/latex/required/psnfss/changes.txt

Yes and I think that this is the main reason for the changes. E.g. many
fonts (including the urw35) now have the Euro, so it was added.
