Add Custom Events

Always Emit New Event Log​

We recommend adding new events instead of modifying existing ones.

Before:

/// @notice Emitted when a user revokes all delegations for a given delegate
event RevokeDelegate(address vault, address delegate);

emit IDelegationRegistry.RevokeDelegate(vault, msg.sender);

After

/// @notice Emitted when a user revokes all delegations for a given delegate
event RevokeDelegate(address vault, address delegate);
event RevokeDelegateRevised(
   address vault,
   address delegate
);

emit IDelegationRegistry.RevokeDelegate(vault, msg.sender);
emit IDelegationRegistry.RevokeDelegateRevised(
   vault,
   delegate
);
