❗ 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
✨ The Ecotone upgrade brings 4844 and Cancun extensions to the L2.
⚡ Other features in this release include experimental snap sync support for trusted environments and improved shutdown behavior of op-batcher
Config changes:
With the Ecotone upgrade, op-node needs to connect to an L1 beacon client in order to be able to fetch blobs, whose endpoint is specified with the --l1.beacon flag (or OP_NODE_L1_BEACON env var). If you are using a Lighthouse CL client, you must update to at least the v4.6.0 finalized release.
