Version 2.2.4

In this release

This release contains a new NODE support and improvements of WebSocket and HTTP API.

See below for more information.

Migration

In this release we improved log messages about misconfiguration. To do this we migrated to the different configuration library. Also we updated some settings keys: some of them now have clear names, some of them we had to update as a part library's migration. Update following settings if you have them.

• waves.dex.order-history.enabled to waves.dex.order-history.enable
• waves.dex.account-storage.in-mem.seed-in-base64 to waves.dex.account-storage.in-mem.seed-in-base-64
• waves.dex.max-price-deviations.profit to waves.dex.max-price-deviations.max-price-profit
• waves.dex.max-price-deviations.loss to waves.dex.max-price-deviations.max-price-loss
• waves.dex.max-price-deviations.fee to waves.dex.max-price-deviations.max-fee-deviation

Changes

• Support of NODE 1.2.14;
• Matcher now can accept orders with a custom fee with current or previous rate of asset. This improves a situation with a rare issue when a client sends an order and Matcher updates the rate of asset this time;
• WebSocket API improvements:
  • Added a subscription on rate changes;
  • Added an amount of changed price assets in orders to address subscription;
  • Added some stats about connections (client and OS if the client specified this information);
  • Bids in an order book subscription now sorted in a descending order as it should be;
  • Increased the default time between pings and expected pongs;
• HTTP API improvements:
  • Added an admin endpoint to see matcher's config without sensitive data (seed, password, username, etc): GET /matcher/debug/config;
  • The market status endpoint GET /matcher/orderbook/{amountAsset}/{priceAsset}/status returns an empty JSON with 200 status even if there were no trades. It returned 404 before;
  • A better error if a client wasn't specified Content-Type header;
• Other internal improvements.
