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!
