You can compare with the old profiles on steephill.tv.
Marginal change to stage 3, the tiny bump is removed and the finish is 3.3 km further from the climbs.
I feel like that might have a pretty significant impact on the stage though. The stage now ends with 12 entirely flat kilometres, so this seems more likely to end in a bunch sprint now. I think the original version would have caused a very, very interesting battle for pink.
Edit: So the only climb remaining in the finale got changed as well? That really sucks actually. Man, I was really looking forward to that stage.
And another edit: It's kinda funny though how they changed the stages but now their ratings. Stages 3 and 4 are now both 3 star stages but one is a pretty flat stage, likely for the sprinters, while the other one has a mtf and will have a proper gc battle
