Warning

This is a security hot-fix release. Specifically, this release fixes CVE-2026-26314, CVE-2026-26315 which have been found in go-ethereum.

We recommend recreating your p2p node key after installing this update, which you can do by removing the <DATADIR>/geth/nodekey file before restarting geth. Note this will cause a change in the p2p node ID (enode), which may affect static peering connections.
It does not require an update on consensus client (op-node)

What's Changed

Backport p2p fixes to release by @palango in #476

Full Changelog: celo-v2.1.3...celo-v2.1.4

Celo v2.1.0 release for Mainnet

Overview

This release adds support for the Holocene and Isthmus upgrades on Celo. For more information see the documentation.

The Mainnet activation timestamp is 1752073200: Wed Jul 09 2025 15:00:00 UTC

What's Changed

Due to our rebasing process it's difficult to provide a complete list of commits that have been added since the last release, however a complete diff since the last release can be seen here.

What's included in Isthmus

Isthmus contains these main changes:

Implement Prague features on the OP Stack: This includes the EIPs that are relevant to the L2 that are being added to Ethereum with its Pectra activation. Learn more about this here.

Notable EIP's included:

EIP-7702: Set code transaction
EIP-2537: BLS12-381 precompiles
EIP-2935: Block hashes contract predeploy
EIP-7623: Increase calldata cost
L2 Withdrawals Root in Block Header: This lowers the lift for chain operators by allowing them to run a full node to operate op-dispute-mon, making it easier to guarantee the security of the fault proofs for the chains in the Superchain as the number of chains scales. Learn more about this here.

For more information on the Isthmus implementation details, please review OP's Isthmus specification.

Isthmus additionally enables the Holocene hardfork with the following changes:

Holocene block derivation: A set of changes that render the derivation pipeline stricter and simpler, improving worst-case scenarios for the Fault Proof System and Interoperability.
EIP-1559 configurability: The elasticity and denominator EIP-1559 parameters become configurable via the SystemConfig L1 contract, allowing the gas target and gas limit to be configured independently.
For more information on the Holocene details, please review OP's Holocene specification.

Pre-release

Same changes as the v2.1.0-rc but with a fix for a proper HF overrides from the client side for every already running node

Overview

This release adds support for the Holocene and Isthmus upgrades on Celo. For more information see the documentation.

This release should be skipped for Mainnet. It includes the Isthmus activation timestamps for Baklava and Alfajores Testnets.

The Baklava activation timestamp is 1749654000: Wed Jun 11 2025 15:00:00 UTC
