Description

One of 32 identical deployments of the canonical Truffle Migrations contract (unmodified). Public owner and uint public last_completed_migration slots; a restricted modifier that gates state changes to the deployer; setCompleted(uint completed) writes the migration index; upgrade(address new_address) hands off to a new Migrations by calling its setCompleted(last_completed_migration). Compiled with solc 0.4.24+commit.e67f0147 optimizer ON runs=200. Exact code match; only trailing 34-byte Swarm metadata differs.
