v0.8.1

⬆️ This is a recommended release for node operators using Snap Sync on Base Mainnet & Sepolia. For other users, this is a minor release. Node operators should be on at least v0.8.0.

Changes

• This release contains a fix to snap sync to ensure that all blocks are inserted to the execution engine when snap sync completes. Previously once snap sync would complete, if blocks where received out of order, the op-node could have internally inconsistent state & the unsafe head could stall for a period of time.
• This release also contains a safeDB feature which tracks the L1 block L2 blocks are derived from.

v0.8.0

Protocol

❗ This is a mandatory release for Base Mainnet node operators. It includes the following protocol upgrade activation:

• Ecotone activates on Mainnet at Thu Mar 14 00:00:01 UTC 2024

✨ The Ecotone upgrade brings 4844 and Cancun extensions to the L2.

Config changes

• For Ecotone, op-node needs to connect to an L1 beacon client to be able to fetch blobs. You must specify the endpoint 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.

v0.7.1

❗ This is a mandatory release for node operators on Sepolia. It includes the following protocol upgrade activation:

• Ecotone activates on Sepolia at Wed Feb 21 17:00:00 UTC 2024

✨ The Ecotone upgrade brings 4844 and Cancun extensions to the L2.
🐛 This release also contains a fix for a tx receipt cache bug which would sometimes result in finalized/safe head stall

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.

✨ 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.

v0.6.1

❗ This is a recommended release for Base Mainnet. Upgrading to v0.6.0 or higher is required before 2024-01-11 for the Canyon hardfork which activates at Thu Jan 11 17:00:01 UTC 2024 (unix timestamp: 1704992401).

Upgrades op-node/op-batcher/op-proposer from v1.4.0 to v1.4.1.

If you are using custom configuration or entrypoint scripts and haven't already made the changes recommended in release 0.5.0, please ensure you:

• op-node: set the OP_NODE_NETWORK variable, or use the --network flag. The value is one of base-goerli, base-sepolia, base-mainnet.
• op-geth: set the --op-network flag, passing the same network value as above (one of base-goerli, base-sepolia, base-mainnet)
• op-geth: enable the --rollup.superchain-upgrades flag

v0.6.0

❗ This is a mandatory release for Base Mainnet and upgrading is required before 2024-01-10. This includes all features required for the mainnet Canyon hardfork which will be activating at Thu Jan 11 17:00:01 UTC 2024 (unix timestamp: 1704992401).

❗ This is a mandatory release for Base 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.

Upgrades the node software:

• op-node v1.4.0
• op-geth v1.101304.2

Important note: If you are running a batcher or proposer please use the op-batcher/v1.4.1 and op-proposer/v1.4.1 hotfixes.

v0.5.1

Upgraded the node software:

• op-node v1.3.1
• op-geth v1.101304.1

This is an optional release with some non-critical fixes for the base goerli & sepolia Canyon hardfork (primarily: ignoring any P2P blocks that contain withdrawals), as well as setting some suggested flags (see #139):

• op-node: --rollup.load-protocol-versions=true
• op-geth: --rollup.halt=major
• op-geth: removing optional --rollup.superchain-upgrades

Also adds some quality of life envvars for reducing required disk space (see #146):

• Setting OP_GETH_GCMODE=full supports running a full node (defaults to archive)
• Setting OP_GETH_STATE_SCHEME=path switches the Ethereum state storage scheme to path (defaults to hash)
