Release v1.38.0

Good day Lodestar users! We just released v1.38.0 which introduces performance improvements for your post-Fusaka nodes. This upgrade is highly recommended if you've seen performance declines since the Fusaka fork.

Lodestar is now using nodeJS v24 by default, which introduces improved performance metrics, seen especially by supernodes. If you are building from source, we recommend that you use nodeJS v24, the current LTS as of October.

Note that holesky configurations have been removed and will no longer be a network configuration option.

Happy holidays and see you in 2026! 🚀

Release v1.37.0

Happy December Lodestar users! We just published a recommended maintenance release v1.37.0 for all networks. This release includes a performance fix seen in other Fusaka testnets and also includes a validator client option to disable slot skipping for Obol users (enabled by default when using the --distributed flag).

Both versions, v1.36.0 and v1.37.0 remain compatible for the Fusaka mainnet hard fork on December 3rd.

See you in Fusaka! 🦓

Release v1.36.0

Happy November Lodestar users! We are excited to announce our Fusaka mainnet release with version 1.36.0!

It is mandatory for all node operators to utilize this version or above to be Fusaka fork ready for the scheduled December 3rd hard fork and subsequent BPO forks: BPO1 (December 9th) and BPO2 (January 7th). A reminder for node operators that if you do not run Lodestar or any client with validators and wish to custody all data columns sidecars with your beacon node, you must use the --supernode flag to indicate this, otherwise your node will, by default, custody the minimum amount of 4 or higher depending on your attached validator count.

We have introduced a --semiSupernode flag for more efficient data availability with lower bandwidth and storage requirements. This will custody half the data column sidecar subnets to support blob reconstruction should you need them for other dependents. See #8568 for full details.

This release also increases the default gas limit to signal for 60 million gas blocks, up from the 45 million gas blocks currently on mainnet.

Other optimizations and performance enhancements found on testnets and from the Fusaka bug bounty have also been included with this version.

As usual, ensure you've updated your entire stack to mainnet-ready versions of Fusaka alongside your Lodestar beacon node/validator client. Happy Fusaka fork everyone ! 🍴🦓

Release v1.35.0

Hey Lodestar users! We're happy to release v1.35.0 which includes performance refactors and enhancements! This upgrade is recommended for all mainnet and testnet users.

For node operators, we now support dual stack IPv4 and IPv6 by default serving port 9000. If no listenAddress is specified then we will enable both IPv4 and IPv6. If you want to reconfigure the listening addresses or explicitly enable one stack, you can manually set it for IPv4 only with listenAddress or for IPv6 only with listenAddress6.

This release also supports the Fusaka hard fork on all planned testnets for Holesky, Sepolia and Hoodi. Note that any v1.35.0-rc.X versions are still compatible for the Fusaka testnet forks, but we now recommend using the stable release.
