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
