Horizon v2.4.0

Upgrading to this version from <= v2.1.1 will trigger a state rebuild. During this process (which can take up to 20 minutes), Horizon will not ingest new ledgers.

DB State Migration

• This release comes with a small DB schema change (new multiplexed-account-related columns are incorporated). It should not take more than five minutes to run due to new columns being NULL-able.

Deprecations

• Deprecate --captive-core-config-append-path in favor of --captive-core-config-path. The difference between the two flags is that --captive-core-config-path will validate the configuration file to reject any fields which are not supported by captive core (3629).

New features

• Add more in-depth Prometheus metrics (count & duration) for db queries. (3597, 3605)

• HTTP request logs will now print the Origin header if Referer is not set. (3599)

• Add Multiplexed Account details to API responses (additional _muxed and _muxed_id optional fields following what's described in SEP 23):

  • Transactions: account_muxed, account_muxed_id, fee_account and fee_account_muxed.
  • Operations: source_account_muxed, source_account_muxed_id and additional fields depending on the operation (e.g. from_muxed, from_muxed_id, to_muxed and to_muxed_id for Payment operations)
  • Effects: account_muxed, account_muxed_id and additional fields depending on the effect (e.g. seller_muxed and seller_muxed_id for the Trade effect).

Code Changes

• Fix bug in horizon db reingest range command which required the --ingest flag to be set (3625).

• Fix bug in causing database connections to be closed when the HTTP request was cancelled. (3630)
