Deribit Event Nodes is a new feature created to offload traffic from the retail nodes and to decrease latency. This feature is dedicated to handling public subscriptions and allows unauthenticated users to subscribe to raw market data, as well as aggregated ones.

In order to use Deribit Event Nodes, simply change the WebSocket endpoint to the event node endpoint:

- For test: use wss://test.deribit.com/den/ws instead of wss://test.deribit.com/ws/api/v2

- For production: use wss://streams.deribit.com/ws/api/v2 instead of wss://www.deribit.com/ws/api/v2.

public/get_instrument: the field future_type is deprecated and will be replaced by the new field instrument_type.

Add optional start_timestamp and end_timestamp filters to:

- public/get_last_trades_by_currency

- public/get_last_trades_by_instrument

- private/get_user_trades_by_currency

- private/get_user_trades_by_instrument

order object:

- New optional field mobile with the value true for orders made with the mobile app.

- New cancel_reason field with the reason why the order was canceled.

Affected endpoints:

- private/get_open_orders_by_currency

- private/get_open_orders_by_instrument

- private/get_order_history_by_currency
