No, dave. The optics have not changed, and Tamron has not changed the moulds for the aspheric elements. The "strong and ugly onion ring bokeh" is the same for both versions. Not sure why you think they have improved, as the bokeh test image crop in this review is not a great test to see how its "bokeh balls" perform (and it shows the rings anyway), and the version one lens test on Nikon has no such image to compare.
In short, nothing has changed there.
