Airfoil Bakery will support the Carthage 2.0 Proposal. We are casting our vote in the coming days. If any of our delegators have any last minute suggestions, please feel free to reach out to us.
Much of the Carthage proposal is related to small fixes that clean up bits of the Babylon proposal. There are small tweaks to the smart contract gas limit which allows for more complex smart contracts. The reward formula is also tweaked a bit. You can read up on the Carthage 2.0 fixes here and here.
