v21.8.1

Upcoming Breaking Changes

• The /teku/v1/beacon/states/:state_id endpoint has been deprecated in favor of the standard API /eth/v1/debug/beacon/states/:state_id which now returns the state as SSZ when the Accept: application/octet-stream header is specified on the request.
• The /eth/v1/debug/beacon/states/:state_id endpoint has been deprecated in favor of the v2 Altair endpoint /eth/v2/debug/beacon/states/:state_id
• The /eth/v1/beacon/blocks/:block_id endpoint has been deprecated in favor of the v2 Altair endpoint /eth/v2/beacon/blocks/:block_id
• The /eth/v1/validator/blocks/:slot endpoint has been deprecated in favor of the v2 Altair endpoint /eth/v2/validator/blocks/:slot

Additions and Improvements

• Added command line option --validators-early-attestations-enabled, which defaults to true.
  When using a load balanced beacon node, this option should be disabled.
• Added additional bootnodes for the Prater testnet to improve peer discovery.
• Improved peer discovery. All authenticated node sessions are evaluated as potential peers to connect.
• Improved clarity of sync progress log messages.

Bug Fixes

• Added a column size and percentage complete to migrate-database command, where columns contain block or state objects, as they can be time consuming to copy.
• Fixed issue in Altair where sync committee contribution gossip could be incorrectly rejected when received at the very end of the slot.
• Posting attestations that fail validation to /eth/v1/beacon/pool/attestations will now result in SC_BAD_REQUEST response, with details of the invalid attestations in the response body.
