- CIP-45: Relax canPayFee condition for non-native tokens
- CIP-50: Allow unprotected transactions

Please note that reverting to Celo blockchain v1.4.0 or prior after upgrading to v1.5.0 is not possible without a resync because the blockchain database layout has changed. Please take a backup of the data directory to be able to downgrade.
