Breaking Changes

• External signing API now uses the data field instead of signingRoot field when making signing requests. Update Eth2Signer to ensure it is compatible with this change.

Additions and Improvements

• Further reduced memory usage during periods of non-finalization. Checkpoint states can now be dropped from memory and regenerated on demand.
• Added additional metrics:
  • beacon_peer_count tracks the number of connected peers which have completed chain validation
  • network_peer_chain_validation_attempts tracks the number and status of peer chain validations
  • network_peer_connection_attempt_count tracks the number and status of outbound peer requests made
  • network_peer_reputation_cache_size reports the size of the peer reputation cache
  • beacon_block_import_total tracks the number of blocks imported
  • beacon_reorgs_total tracks the number of times a different fork is chosen as the new chain head
  • beacon_published_attestation_total tracks the total number of attestations sent to the gossip network
• External signing API now uses the data field instead of signingRoot field when making signing requests. Eth2Signer has been updated with this change.
• Enforced the 256 byte limit for Req/Resp error messages
• Blocks by range requests which exceed the maximum block request count are now rejected rather than partially processed as required by the P2P specification
• Improved tracking of peer reputation to avoid reattempting connections to peers we have previously rejected
• ForkChoice data is now persistent to disk, improving startup times especially during long periods of non-finalization
• Reduced the maximum number of blocks held in memory to reduce memory consumption during periods of non-finalization
• Increased the defaults for the target peer count range
• Actively manage peers to ensure we have at least some peers on each of the attestation subnets
• Maintain a minimum number of randomly selected peers, created via outbound connections to provide Sybil resistance
• Updated dependencies to latest versions

Bug Fixes

• Fixed issue where the validator produced attestations in the incorrect slot or committee resulting in Produce invalid attestation messages
• Fixed an issue where attestations were not published to gossip when the node was not subscribed to the attestation subnet
• Fixed a number of unhandled exceptions in discv5
• Fixed an issue where discv5 may return node responses with a total greater than 5
• Fixed Trying to reuse disposable LengthPrefixedPayloadDecoder exception
• Fixed an issue where peers were not disconnected when the initial status exchange failed
• Fixed NullPointerException when validating attestations which became too old during validation
• Updated the EXPOSE ports listed in the Dockerfile to match the new defaults
• Fixed time until genesis log message to handle time zones correctly
• Fixed NoSuchElementException when running a validator that was not in active status
• Fixed IndexOutOfBoundsException when validating an IndexedAttestation which included invalid validator indices
