Changelog

All notable changes to this project will be documented in this file. This project adheres to Semantic Versioning.

As this project is pre 1.0, breaking changes may happen for minor version bumps. A breaking change will get clearly notified in this log.

Unreleased

Added

  • Operation and payment resources were changed to add a transaction_hash property.

v0.11.0 - 2017-08-15

Bug fixes

  • The ingestion system can now properly import envelopes that contain signatures that are zero-length strings.
  • BREAKING CHANGE: specifying a limit of 0 now triggers an error instead of interpreting the value to mean "use the default limit".
  • Requests that ask for more records than the maximum page size now trigger a bad request error, instead of an internal server error.
  • Upstream bug fixes to xdr decoding from github.com/stellar/go.

Changed

  • BREAKING CHANGE: The payments endpoint now includes account_merge operations in the response.
  • "Finished Request" log lines now include additional fields: streaming, path, ip, and host.
  • Responses now include a Content-Disposition: inline header.

v0.10.1 - 2017-03-29

Fixed

  • Ingestion was fixed to protect against text memos that contain null bytes. While memos with null bytes are legal in stellar-core, PostgreSQL does not support such values in string columns. Horizon now strips those null bytes to fix the issue.

v0.10.0 - 2017-03-20

This is a fix release for v0.9.0 and v0.9.1

Added

  • Added horizon db clear helper command to clear previously ingested history.

Fixed

  • Embedded sql files for the database schema have been fixed agsain to be compatible with postgres 9.5. The configuration setting row_security has been removed from the dumped files.

v0.9.1 - 2017-03-20

Fixed

  • Embedded sql files for the database schema have been fixed to be compatible with postgres 9.5. The configuration setting idle_in_transaction_session_timeout has been removed from the dumped files.

v0.9.0 - 2017-03-20

This release was retracted due to a bug discovered after release.

Added

  • Horizon now exposes the stellar network protocol in several places: It shows the currently reported protocol version (as returned by the stellar-core info command) on the root endpoint, and it reports the protocol version of each ledger resource.
  • Trade resources now include a created_at timestamp.

Fixed

  • BREAKING CHANGE: The reingestion process has been updated. Prior versions of horizon would enter a failed state when a gap between the imported history and the stellar-core database formed or when a previously imported ledger was no longer found in the stellar-core database. This usually occurs when running stellar-core with the CATCHUP_RECENT config option. With these changed, horizon will automatically trim "abandonded" ledgers: ledgers that are older than the core elder ledger.

v0.8.0 - 2017-02-07

Added

  • account signer resources now contain a type specifying the type of the signer: ed25519_public_key, sha256_hash, and preauth_tx are the present values used for the respective signer types.

Changed

  • The public_key field on signer effects and an account's signer summary has been renamed to key to reflect that new signer types are not necessarily specifying a public key anymore.

Deprecated

  • The public_key field on account signers and signer effects are deprecated

v0.7.1 - 2017-01-12

Bug fixes

  • Trade resources now include "bought_amount" and "sold_amount" fields when being viewed through the "Orderbook Trades" endpoint.
  • Fixes #322: orderbook summaries with over 20 bids now return the correct price levels, starting with the closest to the spread.

v0.7.0 - 2017-01-10

Added

  • The account resource now includes links to the account's trades and data values.

Bug fixes

  • Fixes paging_token attribute of account resource
  • Fixes race conditions in friendbot
  • Fixes #202: Add price and price_r to "manage_offer" operation resources
  • Fixes #318: order books for the native currency now filters correctly.

v0.6.2 - 2016-08-18

Bug fixes

  • Fixes streaming (SSE) requests, which were broken in v0.6.0

v0.6.1 - 2016-07-26

Bug fixes

  • Fixed an issue where accounts were not being properly returned when the history database had no record of the account.

v0.6.0 - 2016-07-20

This release contains the initial implementation of the "Abridged History System". It allows a horizon system to be operated without complete knowledge of the ledger's history. With this release, horizon will start ingesting data from the earliest point known to the connected stellar-core instance, rather than ledger 1 as it behaved previously. See the admin guide section titled "Ingesting stellar-core data" for more details.

Added

  • Elder ledgers have been introduced: An elder ledger is the oldest ledger known to a db. For example, the core_elder_ledger attribute on the root endpoint refers to the oldest known ledger stored in the connected stellar-core database.
  • Added the history-retention-count command line flag, used to specify the amount of historical data to keep in the history db. This is expressed as a number of ledgers, for example a value of 362880 would retain roughly 6 weeks of data given an average of 10 seconds per ledger.
  • Added the history-stale-threshold command line flag to enable stale history protection. See the admin guide for more info.
  • Horizon now reports the last ledger ingested to stellar-core using the setcursor command.
  • Requests for data that precede the recorded window of history stored by horizon will receive a 410 Gone http response to allow software to differentiate from other "not found" situations.
  • The new db reap command will manually trigger the deletion of unretained historical data
  • A background process on the server now deletes unretained historical once per hour.

Changed

  • BREAKING: When making a streaming request, a normal error response will be returned if an error occurs prior to sending the first event. Additionally, the initial http response and streaming preamble will not be sent until the first event is available.
  • BREAKING: horizon_latest_ledger has renamed to history_latest_ledger
  • Horizon no longer needs to begin the ingestion of historical data from ledger sequence 1.
  • Rows in the history_accounts table are no longer identified using the "Total Order ID" that other historical records use, but are rather using a simple auto-incremented id.

Removed

  • The /accounts endpoint, which lets a consumer page through the entire set of accounts in the ledger, has been removed. The change from complete to an abridged history in horizon makes the endpoint mostly useless, and after consulting with the community we have decided to remove the endpoint.

v0.5.1 - 2016-04-28

Added

  • ManageData operation data is now rendered in the various operation end points.

Bug fixes

  • Transaction memos that contain utf-8 are now properly rendered in browsers by properly setting the charset of the http response.

v0.5.0 - 2016-04-22

Added

  • BREAKING: Horizon can now import data from stellar-core without the aid of the horizon-importer project. This process is now known as "ingestion", and is enabled by either setting the INGEST environment variable to "true" or specifying "--ingest" on the launch arguments for the horizon process. Only one process should be running in this mode for any given horizon database.
  • Add horizon db init, used to install the latest bundled schema for the horizon database.
  • Add horizon db reingest command, used to update outdated or corrupt horizon database information. Admins may now use horizon db reingest outdated to migrate any old data when updated horizon.
  • Added network_passphrase field to root resource.
  • Added fee_meta_xdr field to transaction resource.

Bug fixes

  • Corrected casing on the "offers" link of an account resource.

v0.4.0 - 2016-02-19

Added

  • Add horizon db migrate [up|down|redo] commands, used for installing schema migrations. This work is in service of porting the horizon-importer project directly to horizon.
  • Add support for TLS: specify --tls-cert and --tls-key to enable.
  • Add support for HTTP/2. To enable, use TLS.

Removed

  • BREAKING CHANGE: Removed support for building on go versions lower than 1.6

v0.3.0 - 2016-01-29

Changes

  • Fixed incorrect source_amount attribute on pathfinding responses.
  • BREAKING CHANGE: Sequence numbers are now encoded as strings in JSON responses.
  • Fixed broken link in the successful response to a posted transaction

v0.2.0 - 2015-12-01

Changes

  • BREAKING CHANGE: the address field of a signer in the account resource has been renamed to public_key.
  • BREAKING CHANGE: the address on the account resource has been renamed to account_id.

v0.1.1 - 2015-12-01

Added

  • Github releases are created from tagged travis builds automatically
