23.4.0

This is a recommended update for mainnet, containing a fix for the slow processing of blocks with multiple voluntary exit operations.

Due to some issues with Docker Hub signing service, 23.4.0 docker images have not been signed.

Breaking Changes

• The --p2p-discovery-site-local-addresses-enabled option is set to false by default. If you use the client's discovery inside the local network, update its launch command to toggle the option.

Additions and Improvements

• Added the ability for the CL client to negotiate engine capabilities with the connected EL client. This can be disabled by setting --exchange-capabilities-enabled=false if Shanghai is not supported on your EL client.
• Enabled peer scoring by default. Can be disabled explicitly using --Xp2p-gossip-scoring-enabled=false
• When failovers are configured, the validator client will perform a readiness check on startup to avoid retrieving validator statuses from a node which is not ready.
• Enabled deposit tree snapshot bundles for major networks and persists it after finalization to decrease EL pressure and speed up node startup. Use --deposit-snapshot-enabled=false to disable.
• Optimized validator exit processing during state transition, to speed up block import containing multiple validator exits.
• Locally submitted exits and bls changes will now periodically broadcast if they are not actioned, to address operations being lost in remote pools.

Bug Fixes

• Included All forks in fork schedule if they're defined in configuration.
• • Operation pool not removing some Voluntary Exit messages after block inclusion.
• Slow processing of blocks with multiple voluntary exit operations.

Upcoming Breaking Changes

• The /eth/v1/debug/beacon/heads endpoint has been deprecated in favor of the v2 Bellatrix endpoint /eth/v2/debug/beacon/heads
• The command argument --Xexchange-capabilities-enabled will be removed, update to use --exchange-capabilities-enabled if you are using this option.
• The command argument --Xdeposit-snapshot-enabled will be removed, just remove it from commandline/configuration if you use it, updated argument --deposit-snapshot-enabled defaults to true now.

23.3.1

This is a required update containing mainnet 🦉CAPELLA🦉 fork configuration. All users should upgrade as soon as possible.
NOTE: Upgrade your EL client to the latest version first! This update could be incompatible with old versions.
