Horizon v2.24.1

2.24.1

Changes

• Bump Go to the latest version (1.20.1), including crypto/tls, mime/multipart, net/http, and path/filepath security fixes.

Horizon v2.24.0

2.24.0

Changes

• Add support for the experimental BucketListDB to Horizon, the parameters have been added to the Captive Core configuration / TOML files (4733):

  • BucketListDB is enabled by default when --captive-core-use-db is set and your stellar-core version >= 19.6
  • If --captive-core-use-db set but your stellar-core version < 19.6, an on-disk SQLite database is used (as before).
  • This update will not automatically trigger a state rebuild unless EXPERIMENTAL_BUCKETLIST_DB is set to false in the Captive Core TOML file.

Fixes

• Improve error when setting BUCKET_DIR_PATH and using Captive Core (4736).

Horizon v2.23.1

Changes

• Bump Go to the latest version, including net/http security fixes.

Horizon v2.23.0

Upgrading to this version will trigger a state rebuild. During this process, Horizon will not ingest new ledgers.

Fixes

• Improve performance of /claimable_balances filters. This change should significantly improve ?asset= and ?claimant= filters. (#4690).
• Reallocate slices after offer removals in order book graph. This is done to prevent keeping a large chunks of allocated but unused memory that can lead to OOM crash.
• The ingestion subsystem will now properly use a pool of history archives if more than one is provided. (#4687)
• Add horizon ingest build-state command which builds state at a specific ledger. Useful for debugging. (#4636)

Horizon v2.22.1

Upgrading to this version from <= v2.8.3 will trigger a state rebuild. During this process (which will take at least 10 minutes), Horizon will not ingest new ledgers.

Fixes

• horizon db migrate commands will not apply migrations if ingestion is disabled (4664).

Horizon v2.22.0

Upgrading to this version from <= v2.8.3 will trigger a state rebuild. During this process (which will take at least 10 minutes), Horizon will not ingest new ledgers.

Fixes

• Database migrations will now acquire a lock on ingestion, preventing possible deadlocks (4587).

Changes

• Optimizes startup by preserving the Captive Core storage directory if Horizon has ingested ahead of the requested ledger (4605).

DB Schema Migration

• Introduces a new index that optimizes account queries filtered by asset (4635).

Horizon v2.21.0

Upgrading to this version from <= v2.8.3 will trigger a state rebuild. During this process (which will take at least 10 minutes), Horizon will not ingest new ledgers.

Changes

• Bump Go to the latest version, including net/http and net/url security fixes (4577)

DB Schema Migration

• Added indexes by id for assets in the respective history_trades tables. Ingestion will stop while the migration is being applied. (4565)

Horizon v2.20.0

Upgrading to this version from <= v2.8.3 will trigger a state rebuild. During this process (which will take at least 10 minutes), Horizon will not ingest new ledgers.

DB Schema Migration

• Added indexes by id for claimable balance and liquidity pool id's in the respective tx/ops tables. Ingestion will stop while the migration is being applied. (4455)

Changes

• Orphaned rows in lookup tables (history_accounts, history_claimable_balances and history_liquidity_pools) are removed in small batches after each ledger if --history-retention-count is set. (4518, 4525)
• Improve restart time of Captive-Core when started with --captive-core-use-db flag. The solution does not work on Windows. (4471)
• Fix a bug in which state verifier would run if condition checking DB query fails. (4523)

Horizon v2.19.0

Upgrading to this version from <= v2.8.3 will trigger a state rebuild. During this process (which will take at least 10 minutes), Horizon will not ingest new ledgers.

Breaking Changes

• Update core version to 19.3.0 (4485).
• Pass --console to captive core. This is due to a breaking change in stellar-core 19.3.0 (4487).

Changes

• Run postgres autovacuum on history_trades_60000 table more frequently. (4412).
• Change protocols/horizon.Transaction.AccountSequence to int64 from string. (4409).
• Add missing signer key type names. (4429).
• Update core version to 19.2.0. (4441).
• Add User-Agent header to history archive HTTP requests. (4463).

DB Schema Migration

The migration makes the following schema changes:

• tunes the history_trades_60000 table to run autovacuum more frequently. Migration should be brief, does not incur any data/runtime processing. It does not need a reingestion.

Horizon v2.18.1

• Enabled txsub system to work if/when underlying horizon db connection is read only. (4418)
• Optimize the claimable balance SQL query for best index query plan performance(4398)

DB Schema Migration

There is a new migration step added in this release, it makes the following schema changes:

• creates new, history_transactions_filtered_tmp table related to enabling tx sub processing on read only, only ingest writes to the table. Deprecates, drops prior txsub_results table. Migration should be brief, does not incur any data/runtime processing.
