OP Sepoliav1.4.0 (opens in a new tab)v1.101304.2 (opens in a new tab)

op-node v1.4.0 (opens in a new tab)

Description

This is a mandatory release for OP Sepolia & Goerli and upgrading is required before 2023-12-20. This includes all features required for the Delta Network Upgrade which will be activating at 1703116800 Thu Dec 21 00:00:00 UTC 2023 for Goerli & at 1703203200 Fri Dec 22 00:00:00 UTC 2023 for Sepolia.

  • Span Batches is added to this version of op-node & op-batcher. It will automatically activate on the op-node with the Delta network upgrade timestamp. It can be activated on the batcher by setting the --batch-type flag to 1.
  • The --engine-sync flag is being deprecated.
  • The op-node now supports dencun headers

Required action

Upgrade your op-node software.

Suggested action

  • Explicitly specify --op-network (opens in a new tab) with a pre-configured OP Stack network.
  • Set --rollup.load-protocol-versions to true.
  • Optionally, enabling halting your node on breaking changes by setting --rollup.halt=major. This does not shut down your node, but stops syncing once it detects an incompatible protocol version. Your node defaults to not halting, but we recommend setting this to at least major so your node does not produce diverging state.
