❗ This is a mandatory release for Optimism Mainnet and upgrading is required before 2024-01-11.
This release activates Canyon on op-mainnet, base-mainnet, pgn-mainnet, and zora-mainnet. It will activate at Thu Jan 11 17:00:01 UTC 2024 (unix timestamp: 1704992401)
This release also set the protocol version to v5.0.0-1 to indicate that this version of op-geth is compatible with the in development Delta network upgrade.
Lastly, this release sets the --rollup.superchain-upgrades flag to be true by default. This flag will ensure that hardforks are being applied to known networks (detected via the chain ID) even if the --op-network flag is not set. Setting the op-network flag is still the recommended configuration approach.
