horizonclient-v12.0.0 & txnbuild

First version of Horizon Client with protocol 20:Soroban support.

What's Changed

New XDR Schema:

• Support for new XDR schemas.

• Three new operations related to Soroban and state expiration (see Interacting with Soroban via Stellar and State Expiration):

  • invokeHostFunctionOp: Invoke contract actions.
  • bumpExpirationFootprintOp: Bump expiration ledger of specified keys.
  • restoreFootprintOp: Restore expiration of specified ledger keys.

Horizon API Changes:

• /effects can produce two new effects:
  • contract_credited occurs when a Stellar asset moves into its corresponding Stellar Asset Contract instance
  • contract_debited occurs when a Stellar asset moves out of its corresponding Stellar Asset Contract instance
• /assets/:name contains two new fields:
  • num_contracts - the integer quantity of contracts that hold this asset
  • contracts_amount - the total units of that asset held by contracts
• /operations has three new response schemas corresponding to the Soroban operations (described above)

horizon-v2.26.2-pre-soroban

The latest horizon master branch before soroban features were merged in

Horizon v2.26.1

Fixes

• This hotfix allows ledger ingestion to continue in case of a liquidity pool slippage miscalculation. Its only side effect is that /trades and /trade_aggregations may contain incorrect slippage (9a7522e).

Horizon v2.26.0

Changes

• Improve error handling for when stellar-core crashes (4893)
• Suppress Core timeout error in log output such as error ticking app: context deadline exceeded when ingestion state machine is in build state. (4860)

Breaking Changes

• Modify the default value of --captive-core-use-db to true (4856)
  • This updates the default behavior of captive core to start in on-disk mode.
  • To continue using the previous in-memory mode, explicitly set the --captive-core-use-db flag to false

Horizon v2.25.0

2.25.0

Changes

• Running Horizon with remote captive core is now deprecated (4826).
• Add two new configuration variables to control the behavior of state verification (4821):
  • --ingest-state-verification-frequency which specifies the frequency in checkpoints for how often state verification is run
  • --ingest-state-verification-timeout which specifies a timeout on how long state verification can run

Fixes

• Fix crash in horizon ingestion when running horizon with a remote captive core (4824).

horizonclient & txnbuild v11.0.0

v11.0.0 - 2023-03-29

Breaking Changes

• Minimum Golang version changed to 1.18
• Type of AccountSequence field in protocols/horizon.Account was changed to int64.
• Muxed accounts and ID memos can be used in the BuildChallengeTx() and ReadChallengeTx() SEP-10 utilitiy functions to identify users of shared Stellar accounts. (#4746)
  • BuildChallengeTx():
    • Muxed account addresses can be passed as the clientAccountID.
    • Adds an additional parameter of type *txnbuild.MemoID. Memos cannot be specified if the clientAccoutID id a muxed account address.
  • ReadChallengeTx():
    • Muxed account addresses may be returned as the clientAccountID.
    • Adds an additional return value of type *txnbuild.MemoID.

Full Changelog: stellar/go@horizonclient-v10.0.0...horizonclient-v11.0.0

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)
