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

Release Candidate. Do not use in production.

horizonclient v1.3.0 & txnbuild v1.3.0

horizonclient

• Transaction information returned by methods now contain new fields: FeeCharged and MaxFee. FeePaid is deprecated and will be removed in later versions.
• Improved unit test for Client.FetchTimebounds method.
• 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.
