Overview

Note

This is a patch release of op-proposer containing fixes to dispute game history scanning, a configuration rename, and dependency updates. It is an optional but recommended upgrade for all users.

Note: super dispute games (interop) are coming in Upgrade 20. Changes supporting those game types in this release are preparation for that functionality and do not affect operators today.

What's Changed

Bug fixes

The dispute game history scan that drives proposal throttling now reads each game's cutoff and type from the factory before making any game-proxy call, and uses the common gameCreator() and rootClaim() getters rather than fault-game-specific ones. This removes a metadata call per game outside the scan window, and lets the same throttling path work across fault, super-fault and super-permissioned games. Historical fault games predating gameCreator() still resolve via the claimData(0) fallback (#21741, #21780)
Transaction receipt not found err="context canceled" is no longer logged after a proposal has already confirmed. Multiple receipt waiters are started across publish attempts, and the leftovers logged this on normal cleanup (#21317)

Other

--supernode-rpcs is renamed to --superroot-rpcs, and OP_PROPOSER_SUPERNODE_RPCS to OP_PROPOSER_SUPERROOT_RPCS, reflecting that the source may be either an op-node or an op-supernode. The old flag and environment variable names continue to work, and proposal-source selection is unchanged (#21779)
Gas estimation for proposal transactions no longer pins the gas ceiling and now carries the EIP-1559 fee caps through to eth_estimateGas. Current behaviour is unchanged; the fixed 2^24 cap would have made valid transactions unestimatable on EIP-8037-aware L1 nodes (#22217, #21714)
