Agreed, I also think that PF somehow changed the compound of their PF08 pads becasue the squealing is so much reduced compared to last year.

But the clips could also have an impact. Usually, squealing is caused by the pads vibrating at a high frequency against the calipers and piston. It is that high frequency vibration that causes the squeal. The anit-rattle clips could help in dampening that vibration.

I have no evidence that PF changed the compound, but the addition of the anti-rattle clips is a certainty .
