+### Finality on Upgrade
+
+When upgrading from an `op-proposer` proposing optimistic output roots with a non-zero `finalizationPeriod`, all proposed output roots will be automatically finalized after the upgrade (by default the `finalizationPeriod` is set to 0 in `op-succinct`). For security, we recommend ensuring that all old proposer output roots are correct before upgrading.
