All of Shulk's (A) attacks do 1% more. His jab combo does 3-4-5 damage for a total of 12%.
Also, maybe it's just me, but I don't really feel any immediate jumps of differences with Lucario post patch, unless they made the landing lag for missing a ledge sweetspot with extremespeed worse (it feels like they made it much worse, but at the same time, you're almost never landing like this).
If they did nerf aura, I think someone else is gonna need to test it extensively. At around 160% for Lucario, and 60% for the opponent (Little Mac as the test dummy), any smash from center stage insta-KOs, force palm grab needs the opponent to be at like 80%ish for an instant KO from center stage. At around 120% for Lucario, and around 40% for the opponent, you're not KOing them from center stage, but smashes still do a lot of knockback from center stage. Back-air is respectable knockback, as is the FP grab so.... I dunno.
Recovery might be slightly worse? I dunno, you still shoot off into space around 70%+.
EDIT: I tried matching up a few numbers with the aura scaling chart made by Myth, I don't have time to do all of it, but from what I tested, the % dealt hasn't really changed. So I think we're going to have to look at knockback differences if anything. Lucario isn't exactly the type to KO from the center of the stage without smashes anyway.
Also it seems like the first two hits of the jab connect with each other better, but the third hit is still dumb and requires you to slow down your jab combo to make sure all three hits connect when you and your opponent are at like >60%.
