The OP Sepolia testnet is scheduled for an upgrade on March 19, 2024, to support the feature-complete version of OP Stack fault proofs. 

 Developers are advised to update  their smart contract logic and withdrawal monitoring services to work with the new DisputeGameFactory contract instead of the existing L2OutputOracle.

Bridges, exchanges and other services using withdrawals will need to update to support looking up withdrawal claims from DisputeGame contracts instead of outputs.
