Horizon v2.27.0 Release Candidate

on GitHub

Upgrading to this version from <= 2.26.1 will trigger a state rebuild. During this process (which will take at least 10 minutes), Horizon will not ingest new ledgers.

This release adds support for Protocol 20

Breaking Changes

• The command line flag --remote-captive-core-url has been removed, as remote captive core functionality is now deprecated (4940).

Added

• Added new command-line flag --network to specify the Stellar network (pubnet or testnet), aiming at simplifying the configuration process by automatically configuring the following parameters based on the chosen network: --history-archive-urls, --network-passphrase, and --captive-core-config-path (4949).
• Added contract_credited and contract_debited effects which are emitted whenever a Soroban contracts sends or receives a Stellar asset (4832).

• Added num_contracts (total number of Soroban contracts which hold an asset) and contracts_amount (total amount of the asset held by all Soroban contracts) fields to asset stat summaries at /assets (4805).
• Added responses for new operations introduced in protocol 20: invoke_host_function, bump_footprint_expiration, and restore_footprint (4905).

Fixed

• The same slippage calculation from the v2.26.1 hotfix now properly excludes spikes for smoother trade aggregation plots (4999).
