Summary

This high-priority hot-fix address high CPU usage experienced after the Capella upgrade (April 12 UTC).

We recommend all mainnet users update to this release to prevent high CPU usage from interfering with normal node operations (e.g., staking).

This hot-fix only applies to the Beacon Node. There is no need to upgrade the Validator Client from v4.0.1 (or v4.0.1-rc.0) to this release.

Building from Source

This hot-fix is not yet applied to the unstable or stable branches. To build from source, use the hotfix-exit-verification branch (or checkout the v4.0.2-rc.0 tag).
