Optimism op-supernode v1.0.3 Adds Stricter Hardfork Configuration Checks
Summary
Optimism released optional op-supernode v1.0.3 on October 1, adding stricter checks for hardfork schedules in virtual-node rollup configurations. From the Jovian fork onward, the software rejects configurations that assign multiple hardforks the same post-genesis activation time or put later forks out of order. Existing chains in the Superchain registry are unaffected; operators using custom configurations may need to fix invalid schedules before upgrading. The update aims to catch configuration errors at startup before they cause inconsistencies across chain components.
