Horizon v1.0.0 Compatibility.

Added

  • Add support for top-level offers endpoint with seller, selling, and buying filter.
    Horizon 1.0 includes a new /offers end-point, which allows you to list all offers, supporting filtering by seller, selling, or buying asset.

    You can fetch data from this endpoint by doing server.offers() and use any of the following filters:

    • seller: server.offers().for_seller(account_id)
    • buying: server.offers().for_buying(asset)
    • selling: server.offers().for_selling(asset)
    • offer detail : server.offers().offer(offer_id)

    This introduced a breaking change since it modified the signature for the function server.offers().

    Before, if you wanted to list all the offers for a given account, you'd do:

    server.offers(account_id)

    Starting on this version you'll need to do:

    server.offers().for_seller(account_id)

    You can do now things that were not possible before, like finding
    all offers for an account filtering by the selling or buying asset

    server.offers().for_seller(account_id).for_buying(buying_asset).for_selling(selling_asset)

  • Add support for filtering accounts by signer or asset, this has been released in a previous patch version.
    Horizon 1.0 includes a new /accounts end-point, which allows you to list all accounts who have another account as a signer or hold a given asset.

    You can fetch data from this endpoint by doing server.accounts() and use any of the following filters:

    • acount detail: server.accounts().account_id(account_id), returns a single account.
    • for signer: server.accounts().for_signer(account_id), returns accounts where account_id is a signer.
    • for asset: server.accounts().for_asset(asset), returns accounts which hold the asset.

Changed

  • Regenerate the XDR definitions to include MetaV2 support (also see #1902).

Fixed

  • Fixed some documentation errors.

Breaking

  • Change function signature for server.offers.
    The signature for the function server.offers() was changed to bring support for other filters.

    Before, if you wanted to list all the offers for a given account, you'd do:

    server.offers(account_id)

    Starting on this version you'll need to do:

    server.offers().for_seller(account_id)
  • server.accounts().signer and server.accounts().asset are marked as deprecated, use server.accounts().for_signer and server.accounts().for_asset instead.

There are also some changes related to the horizon's response, currently, SDK has not added parse support to it,
so please refer to this issue or release notes of Stellar horizon 1.0.0. In addition, support for parsing the horizon's responses will be added in the next major update.
