Dan, the feature ("Place .OP Data Label") was in LTspice IV too, but it doesn't go back to LTspice's beginning, so very early versions (MANY years old) did not have it.? The Changelog shows that it goes back at least as early as 2010.
I THINK it was added to LTspice when it was still at LTspice III (or Switcher CAD III).
