Nothing new Sally, they have been running this for quite sometime.
Personally I wouldnt touch Google CPA with a ten meter cattle prod after the first time we ran it and brought in 5k extra a month to only watch our regular adsense earnings drop by exactly 5k per month to balance our account out to within pennies of it's previous monthly average.
Whats was even worse is that once we removed CPA our regular earnings never came back. A perm 5k per month drop.
