Release v1.39.1

Hey everyone! If you encountered any issues running Lodestar v1.39.0, it's likely because you are running the arm64 docker image which was missing a dependency in the build. If you're one of those users, this upgrade is mandatory and v1.39.1 will fix this issue. Thanks to macfarla of Besu for discovering the issue and sorry for the inconvenience!

Release v1.39.0

Good day Lodestar operators! We've just released v1.39.0 and recommend users update for the latest features and best performance.

We've migrated to using pNPM as our package manager, which requires users who build from source to install pNPM and clean their node_modules folder to prevent conflicts.

To migrate, run the following:

• npm install -g pnpm
• pnpm clean:nm

This will prep the repository for normal command execution.

For Obol validators: Please upgrade to this latest Lodestar validator client version together alongside your cluster operators to prevent any issues with attestation aggregations on your cluster.

This release removes legacy eth1 related code and can no longer produce blocks with deposits pre-Electra, but syncing is still functional. If you use any --eth1.* flags, they will no longer have any effect. This version will no longer support starting a chain pre-Electra.

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! 🦓
