From [Aave v3 Source Code](https://github.com/aave-dao/aave-v3-origin/blob/083bd38a137b42b5df04e22ad4c9e72454365d0d/src/contracts/protocol/pool/PoolStorage.sol#L44) we know that Aave collects FlashLoan Fees from borrowers when they return the loaned amount plus a premium fee at the end of the transaction block. This premium fee consists of a portion sent to the protocol treasury (i.e., `_flashLoanPremiumToProtocol`) and is expressed in bps. By reading the smart contract using json I managed to obtain the current value of `_flashLoanPremiumToProtocol` which is 4 bps (or 0.04%) of the premium total (i.e., `_flashLoanPremiumTotal`), however I am also interested in knowing any historical updates of this value - is there any way which I could obtain this? From Aave documentation we know that `_flashLoanPremiumToProtocol` was initialised at 0, I would therefore like to know the journey between 0 (the starting value) and 4 (the current value) bps.

Also, in the [Aave v2 Source Code](https://github.com/aave/protocol-v2/blob/ce53c4a8c8620125063168620eba0a8a92854eb8/contracts/protocol/lendingpool/LendingPool.sol#L718) there’s only `_flashLoanPremiumTotal`, does it mean that Aave v2 doesn’t allocate any portion of the flashloan fees to the protocol treasury like how v3 does?

Many thanks in advance for advising!
