Matador R3.1?

I have been just told that the gun i’m going to collect tomorrow (one of the 3 just delivered into the uk) is the R3.1, being different from the 3.0 by “minor cosmetical changes on the stock”.
I will know full details once i see it, meanwhile i was wondering if you knew what kind of changes i should expect on the latest matador batches.
I could not find any references on Ed’s website, however i must say that he must be so busy making guns, he has not much time updating the website, which is pretty basic, let alone bothering with a “news” section!
