In this release

We were focused on the WebSocket implementation and small HTTP API improvements.

Migration

No needed.

New

Experimental support of WebSockets

WebSockets API is unstable and breaking changes can be made. So it has an internal status right now.
More information and documentation will be provided in the future releases after stabilization.

Basic server checks in waves-dex-cli

waves-dex-cli now can run basic checks on the Server:

  • It has an expected version;
  • An order could be placed, matched or canceled;
  • A user can connect to the WebSocket API.

It is useful during updates. See waves-dex-cli check-server for more information;

HTTP API endpoints changes

Added two endpoints to retrieve an order information:

  • GET /matcher/orders/{address}/{orderId} - by an API-key;
  • GET /matcher/orders/{publicKey}/{orderId} - by a signature.

Added the closedOnly query parameter to order history endpoints:

  • GET /orderbook/[amountAsset]/[priceAsset]/publicKey/[publicKey]
  • GET /orderbook/[publicKey]
  • GET /orders/[address]

This information is similar to an order history.
