Fixed: - Automatically convert the parameter `to` to a checksum address in the `account.call()` and `account.send_transaction()` methods for a better experience :)
0.7.5
Changes: - If the gas cost of a transaction fails to be estimated, 3,000,000 will be used as the gas limit
0.7.4
Fixed: - Add `GAS_BUFFER` to all `gas` fields
0.7.3
Fixed: - Add an additional buffer of 100000 gas to the result of `estimate_gas()`, according to [web3py docs](https://web3py.readthedocs.io/en/stable/web3.eth.html#web3.eth.Eth.send_transaction)
0.7.2
Fixed: - Use `ContractFunction.estimate_gas()` to estimate transaction gas when calling function, instead of `Web3.eth.estimate_gas()`
0.7.1
Fixed: - The `data` field is included to estimate transaction gas better
