❗ Mandatory update for Base Mainnet nodes to support the Jovian upgrade on December 2nd.

Operators of Base Mainnet nodes must upgrade to this release before December 2nd at UTC 16:00:01 UTC (unix timestamp 1764691201).

⚠️ Breaking Changes (same as v0.14.1)

Similar to v0.14.1 which was a mandatory upgrade for Base Sepolia node operators, this release also contains the following change and will be applied to mainnet node operators now as well.

op-reth Binary Removed, Consolidated into base-reth-node

The separate op-reth binary has been removed and is no longer available.

All functionality previously provided by op-reth has been consolidated into the existing base-reth-node binary.

• Impact: If your deployment or scripts explicitly called the op-reth binary, you must update them to call base-reth-node instead.
• Parameters & Operation: The base-reth-node binary is designed to be identical in its command-line parameters and operational behavior to the removed op-reth. No parameter changes should be necessary other than the binary name itself.
• Reasoning: This consolidation allows us to more easily introduce and manage Base-specific features within a single, unified client binary.

What's Changed

• chore: updated node-reth, reth by @github-actions[bot] in #661

Full Changelog: v0.14.2...v0.14.3

❗ Critical bug fix for Base Sepolia Testnet nodes running Geth client

❗ Hotfix release to fix eth_call with pending state on Flashblock RPCs

What's Changed

• chore: updated node-reth by @github-actions[bot] in #616

Full Changelog: v0.13.3...v0.13.4

❗Do not use

This version introduces a critical bug that causes eth_call with the pending block tag to return incorrect values for Base Reth nodes. Use v0.13.4 instead.

Overview

Recommended release for Reth node operators with Flashblocks enabled to help stabilize flashblock processing and significantly reduce execution errors

What's Changed

• Reth recommended by @anikaraghu in #604
• chore: updated reth, node-reth by @github-actions[bot] in #615

New Contributors

• @anikaraghu made their first contribution in #604

Guidance

This is a recommended release for Reth node operators utilizing Flashblocks functionality as it fixes a bug with eth_getLogs when utilizing Flashblocks pending state for it across mixed-range queries e.g. fromBlock = latest and toBlock = pending
