As Ray has pointed out, the optical design has not been officially 
changed since 1964. However many feel it has been tweaked over the 
years; and that, combined with new coating techniques, means that the 
later lenses are better performers.

When the mount was redesigned to have a close focus of 0.7m and a built 
in hood, all the glass was redesigned to fit in the mount. The new mount

is much better at holding each element in its proper place and 
orientation. They may have tweaked the optical design then as wel,l 
though again, not reported.

If I was going to buy a 50/1.4, I would look for the new design with the

built in hood.
