Any major changes after the 2014 model?

I'm thinking of buying a 2014 model, but I'm wondering if it's worth spending a bit more and geting a newer one - what do you guys think?

The one I'm looking at is £3300 with 45k miles, it's a 'Cat N' which means it has been in an accident but very minor cosmetic damage only. I know the risk, but I am prepared to roll the dice - I've always wanted to own this bike.
