This update is recommended to all users of Lodestar and mandatory for those running Sepolia and Holesky testnets. This release is also ready for the Gnosis Chain Chiado fork.

This release includes some additional fixes for the Deneb hard fork, an upgrade to js-libp2p and minor fixes for UX and performance improvements.

• js-libp2p is now updated to v1.x.
• For DVT, multiple, and fallback node users, we've fixed some logging in relation to already known errors seen in our API.
• By default, we've raised our nodeJS max-old-space-size option from 4096 (4GB) to 8192 (8GB) in our scripts by default so users can benefit from testnets like Holesky with larger states and to better handle periods of network turbulance like non-finality before heap memory is exceeded. This does not increase memory usage. It was done proactively to improve UX as we continue to optimize our memory footprint.
• Improvements were made to UX for exiting batches of validators.
• For users using builder boost factor, our error logging now indicates that this cannot be a number with decimals.
