Horizon v1.0.0 Compatibility

[abuiles]

The upcoming Horizon release is coming, and there are multiple breaking changes plus new features 🎉🎉🎉!

The following are the list of changes required to support this new release:

• [ ] ➕Update /fee_stats response.

  - ✂ Remove the following fields: ```json min_accepted_fee mode_accepted_fee p10_accepted_fee p20_accepted_fee p30_accepted_fee p40_accepted_fee p50_accepted_fee p60_accepted_fee p70_accepted_fee p80_accepted_fee p90_accepted_fee p95_accepted_fee p99_accepted_fee ``` - ➕Add support for `max_fee` and `fee_charged` fields. Each field contains a JSON object that looks like this: ```json { "last_ledger": "22606298", "last_ledger_base_fee": "100", "ledger_capacity_usage": "0.97", "fee_charged": { "max": "100", "min": "100", "mode": "100", "p10": "100", "p20": "100", "p30": "100", "p40": "100", "p50": "100", "p60": "100", "p70": "100", "p80": "100", "p90": "100", "p95": "100", "p99": "100" }, "max_fee": { "max": "100000", "min": "100", "mode": "100", "p10": "100", "p20": "100", "p30": "100", "p40": "100", "p50": "100", "p60": "100", "p70": "100", "p80": "100", "p90": "15000", "p95": "100000", "p99": "100000" } } ``` See https://github.com/stellar/go/pull/2140 for more info.

• [ ] ✂ Remove deprecated fee_paid field from Transaction response (replace it with the fee_charged and max_fee fields, see #1372).

• [ ] 🚨Multiple fields changed from int64 to string. If your SDK has types, they need to be updated. If possible, we recommend implementing backward compatibility support, as we did here.

  - Attribute `offer_id` in [manage buy offer](https://www.stellar.org/developers/horizon/reference/resources/operation.html#manage-buy-offer) and [manage sell offer](https://www.stellar.org/developers/horizon/reference/resources/operation.html#manage-sell-offer) operations. - Attribute `offer_id` in `Trade` effect. - Attribute `id` in [Offer](https://www.stellar.org/developers/horizon/reference/resources/offer.html) resource. - Attribute `timestamp` and `trade_count` in [Trade Aggregation](https://www.stellar.org/developers/horizon/reference/resources/trade_aggregation.html) resource. See https://github.com/stellar/go/issues/1609, https://github.com/stellar/go/pull/1909, and https://github.com/stellar/go/issues/1912 for more info

• [ ] 🚨 Update operation types to canonical names (if needed) (see https://github.com/stellar/go/pull/2134).

• [ ] ➕Add support for /accounts end-point with ?signer and ?asset filters. We recommend a method like .accounts(queryParams) (see documentation for accounts).

• [ ] ➕Add support for /offers end-point with query parameters. We recommend a method like .offers(queryParams) (see documentation for offers).

• [ ] ➕Add support for /paths/strict-send end-point. See documentation. We recommend a method like

  strictSendPaths(sourceAsset, sourceAmount, [destinationAsset])

• [ ] ➕ Add support for /paths/strict-receive end-point. See documentation. We recommend a method like:

  strictReceivePaths(sourceAssets,destinationAsset, destinationAmount)

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

That's it! If you have any questions feel free to ping us on #dev-discussion in Keybase.
