v0.15.1

Breaking Changes (same as v0.15.0)

Important

Node operators must upgrade Base Sepolia nodes to use base-node-reth and base-consensus by 20th April. See here for more information.

The default consensus layer client is now base-consensus. Geth and Nethermind will no longer be supported starting with Base v1.

Action required:

• Configure new BASE_NODE environment variables (see example env files)
• To temporarily opt out, set USE_BASE_CONSENSUS=false

Changes

• Switch all entrypoints to use base-consensus authentication (#1001)
• Add legacy OP node flag (#1002)

New RPCs

Note

These features are only supported in Base Reth

• base_transactionStatus - lookup whether a transaction is present in the mempool
• eth_subscribe - updated to support Flashblocks
  * pendingLogs: stream of logs from transactions in Flashblocks
  * newFlashblockTransactions: stream of transaction hashes that are included in the block
  * newFlashblocks: stream the pending block as new Flashblocks arrive

Other Changes

• Base Reth
  • Flashblock bug fixes and performance improvements
• Nethermind, Geth
  • No changes

Full Changelog: v0.14.3...v0.14.4

v0.14.3

❗ 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

v0.14.2

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

This release contains a critical fix to op-geth in which historical block sync would halt after the Jovian fork.

Note

This release is not required for Sepolia nodes running Reth, but is recommended for some performance improvements that come with the bump
