Horizon v0.20.1 rc1

Release Candidate. Do not use in production.

• Add --ingest-state-reader-temp-set flag (INGEST_STATE_READER_TEMP_SET env variable) which defines the storage type used for temporary objects during state ingestion in the new ingestion system. The possible options are: memory (requires ~1.5GB RAM, fast) and postgres (stores data in temporary table in Postgres, less RAM but slower).

Horizon v0.20.0

If you want to use experimental ingestion skip this version and use v0.20.1 instead. v0.20.0 has a performance issue.

Changes

• Experimental ingestion system is now run concurrently on all Horizon servers (with feature flag set - see below). This improves ingestion availability.
• Add experimental path finding endpoints which use an in memory order book for improved performance. To enable the endpoints set --enable-experimental-ingestion CLI param or ENABLE_EXPERIMENTAL_INGESTION=true env variable. Note that the enable-experimental-ingestion flag enables both the new path finding endpoints and the accounts for signer endpoint. There are two path finding endpoints. /paths/strict-send returns payment paths where both the source and destination assets are fixed. This endpoint is able to answer questions like: "Get me the most EUR possible for my 10 USD." /paths/strict-receive is the other endpoint which is an alias to the existing /paths endpoint.
• --enable-accounts-for-signer CLI param or ENABLE_ACCOUNTS_FOR_SIGNER=true env variable are merged with --enable-experimental-ingestion CLI param or ENABLE_EXPERIMENTAL_INGESTION=true env variable.
• Add experimental get offers by id endpoint/offers/{id} which uses the new ingestion system to fill up the offers table. To enable it, set --enable-experimental-ingestion CLI param or ENABLE_EXPERIMENTAL_INGESTION=true env variable.

Scheduled Breaking Changes

• fee_paid field on Transaction resource has been deprecated and will be removed in 0.22.0. Please use new fields added in 0.18.0: max_fee that defines the maximum fee the source account is willing to pay and fee_charged that defines the fee that was actually paid for a transaction. See CAP-0005 for more information. This change has been previously scheduled for 0.19.0 release.
• The following operation type names have been deprecated: manage_offer and create_passive_offer. The names will be changed to: manage_sell_offer and create_passive_offer in 0.22.0. This has been previously scheduled for 0.19.0 release.
• The type for the following attributes will be changed from int64 to string in 0.22.0:
  • Attribute offer_id in manage buy offer and manage sell offer operations.
  • Attribute offer_id in Trade effect.
  • Attribute id in Offer resource.
  • Attribute timestamp and trade_count in Trade Aggregation resource.

If you are an SDK maintainer, update your code to prepare for this change.

horizonclient v1.4.0 & txnbuild v1.4.0

horizonclient

• Add support for querying operation endpoint with join parameter #1521.
• Add support for querying previous and next trade aggregations with Client.NextTradeAggregationsPage and Client.PrevTradeAggregationsPage methods.

txnbuild

• Add BuildChallengeTx function for building SEP-10 challenge transaction(#1466).
• Add VerifyChallengeTx method for verifying SEP-10 challenge transaction(#1530).
• Add TransactionFromXDR function for building txnbuild.Transaction struct from a base64 XDR transaction envelope#1329.
• Fix bug that allowed multiple calls to Transaction.Build increment the number of operations in a transaction #1448.
• Add Transaction.SignWithKeyString helper method for signing transactions using secret keys as strings.(#1564)

Ticker v1.1.0

v1.1.0

• Added support for running the ticker on Stellar's Test Network, by using the --testnet CLI flag.
• The ticker now retries requests to Horizon if it gets rate-limited.
• Minor bug fixes and performance improvements.

Horizon v0.19.0

• Add join parameter to operations and payments endpoints. Currently, the only valid value for the parameter is transactions. If join=transactions is included in a request then the response will include a transaction field for each operation in the response.
• Add experimental "Accounts For Signers" endpoint. To enable it set --enable-accounts-for-signer CLI param or ENABLE_ACCOUNTS_FOR_SIGNER=true env variable. Additionally new feature requires links to history archive: CLI: --history-archive-urls="archive1,archive2,archive3", env variable: HISTORY_ARCHIVE_URLS="archive1,archive2,archive3". This will expose /accounts endpoint. This requires around 4GB of RAM for initial state ingestion.

Horizon v0.19.0 rc1

• Added Client.HomeDomainForAccount helper method for retrieving the home domain of an account.

txnbuild

• Add support for getting the hex-encoded transaction hash with Transaction.HashHex method.
• TransactionEnvelope is now available after building a transaction(Transaction.Build). Previously, this was only available after signing a transaction. (#1376)
• Add support for getting the TransactionEnvelope struct with Transaction.TxEnvelope method (#1415).
• AllowTrust operations no longer requires the asset issuer, only asset code is required (#1330).
• Transaction.SetDefaultFee method is deprecated and will be removed in the next major release (#1221).
• Transaction.TransactionFee method has been added to get the fee that will be paid for a transaction.
• Transaction.SignHashX method adds support for signing transactions with hash(x) signature types.
