❗Delta & Ecotone Upgrades

This is a mandatory release for node operators on Mainnet and Goerli. It includes two protocol upgrade activations

• Delta activates on Mainnet at Thu Feb 22 00:00:00 UTC 2024
• Ecotone activates on Goerli at Tue Feb 6 17:00:00 UTC 2024

❗ Known issue with alternative execution layer clients (like op-reth)

This release always uses the V3 methods of the Engine API when calling out to the EL client. This breaks with the upstream EL spec, which requires to use the correctly-versioned methods depending on the active fork.

The fix (https://github.com/ethereum-optimism/optimism/pull/9253) is already available in the release candidate op-node/v1.5.1-rc.1. In the meantime, this release is guaranteed to work with op-geth/v1.101305.3. Note that only release from v1.5.0 contain the mainnet Delta and Goerli Ecotone activation times, so if you're running a node on these networks, you must upgrade to at least op-node/v1.5.0. On other networks, you can still use op-node/v1.4.3.

New Beacon Endpoint

It is required for Goerli operators to configure a Beacon endpoint for op-node, because soon after the Ecotone activation, batch transactions will be sent as 4844 blobs, and blobs can only be retrieved from Beacon nodes. If you're using Lighthouse, make sure to use at least the finalized version v4.6.0 because the latest rc contains a bug in its blob_sidecars http endpoint.

The op-node provides a new configuration flag & env var for configuring the Beacon endpoint: --l1.beacon and $OP_NODE_L1_BEACON

Mainnet and Sepolia node operators are strongly encouraged to already get their Beacon node infra set up so that they will be ready to enable their Beacon endpoints once Ecotone activates on Sepolia and Mainnet. Activation dates for these networks will be communicated at a later date.
