Most of the modifications fall under one of these categories:

• removal of functions unused in Balancer V2 source code
• replacement of require statements with the _require function from the BalancerErrors.sol contract
• modification or addition of functionality to reduce bytecode size (see ReentrancyGuard.sol) or gas usage (see EnumerableSet, EnumerableMap or SafeERC20)

Non-trivial modifications in this last category have associated source code comments that explain the changes and motivation.
