They’ve rejigged the number of coins to upgrade, and they’ve thrown in new requirements as well.
For example, taking Goldbite Grimlock from L9 to L10 now costs 150,000 coins + 7 deceptigears + 5 angerchips.
In contrast, taking Optimus Prime from L10 to L11 costs 200,000 coins + 8 cubes of birdium + 6 angerchips + 1 super rareium.
