Release v1.27.0

Good day Lodestar users! Our Pectra testnet-ready release is here with v1.27.0! This update is mandatory for all users on the Ephemery, Holesky and Sepolia networks. It includes fixes to Electra and the hard fork parameters required to enable Pectra on Holesky at epoch 115968 (Feb 24) and Sepolia at epoch 222464 (Mar 5).

For other users, if you had issues with utilizing our binaries with systemd where the exit signal was not properly shutting down the node, v1.27 fixes this.

Happy Pectra forking 🍴🦒!

Release v1.26.0

Good day Lodestar users! We've just released our v1.26.0 update to Lodestar. We recommend all users update when convenient to benefit from some optimizations and fixes. If you previously experienced compile errors with Wasm SIMD unsupported, this release will fix the few amount of CPUs affected since v1.21.

We have removed the mekong network config as this release is no longer compatible with previous specifications used in the mekong testnet. This release is compatible with pectra-devnet-6 for those using Lodestar for Pectra development purposes.

Release v1.25.0

Hey Lodestar users! We've got our first minor release out for 2025. We recommend all users update to Lodestar v1.25.0 when convenient as it comes with a security update and a default gas limit set at 36M as agreed upon as a safe gas limit increase for the network.

Release v1.24.0

Hey everyone! As we wind down 2024, we are happy to announce our year-end release v1.24.0!

This recommended release includes some anticipated features like:

• Using getBlobsV1 to import blobs locally from the execution layer
• Supporting the latest nodeJS LTS version 22 (previously pinned at 22.4)
• Adding the debug_getHistoricalSummaries endpoint to allow accessing HistoricalSummaries on the BeaconState post-Capella
• A very useful one-line terminal command (curl -fsSL https://chainsafe.github.io/lodestar/install | bash) to install the Lodestar executable into your amd64 and arm64 box.
• Adding an experimental keymanager endpoint (GET /eth/v0/validator/{pubkey}/proposer_config) that allows you to retrieve a proposer configuration which you may use to configure different settings such as fee recipient and builder settings on different validator keys. See our documentation for more information: https://chainsafe.github.io/lodestar/run/validator-management/proposer-config

Thank you to all the external contributors also for your work in this release!

We've also published a year in review with some potential insights into our outlook for 2025: https://blog.chainsafe.io/a-lodestar-for-consensus-2024/

Happy holidays and see you in the New Year!
