v21.7.0

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.

Breaking Changes

• Teku no longer publishes a head event on the REST API 4 seconds into a slot if a block has not been received.
  The --Xvalidators-dependent-root-enabled=false option can be used to restore the old behaviour.
  Note: this should be applied to both the beacon node and validator client if running separately.

Additions and Improvements

• Added migrate-data subcommand to allow users to migrate to a leveldb relatively easily without requiring a full re-sync.
• Improved compatibility of the validator client with other beacon nodes using the REST API by using
  the dependent-root field to detect re-orgs instead of depending on the beacon chain publishing re-org events when empty slots are later filled.

Bug Fixes

• Fix an issue where new peers would not be found after a network outage.
• Fix a file handle leak in jvm-libp2p.
• Fix previous_epoch_participation and current_epoch_participation representation in
  /eth/v2/debug/beacon/states/:state_id so that it comes back as an array rather than a byte string.
• /eth/v1/beacon/pool/sync_committees incorrectly returned 503 when there were no errors instead of 200.
• Fix an issue where deposits for the PoW chain could be loaded out of order on restart.
• Fix /eth/v1/validator/contribution_and_proofs to return errors.
• Add SYNC_COMMITTEE_SUBNET_COUNT to /eth/v1/config/spec, as it was missing.
