v0.3.0

What's New

New Features

• QuoteExecuted WebSocket events: New QuoteExecuted variant on CommunicationData enum for quote execution notifications. Previously these were silently dropped on the communications channel.
• UserOrders WebSocket channel: Real-time order update notifications with optional market_tickers filtering (requires authentication).
• Historical data endpoints: 6 new endpoints for accessing archived markets, candlesticks, fills, and orders beyond the rolling cutoff.
• Fixed-point _fp fields: Across REST and WebSocket types for precise decimal values without floating-point rounding.
• Subaccount support: Extended across orders, RFQs, quotes, fills, settlements, order groups, and balance queries.
• Order group enhancements: New trigger_order_group(), update_order_group_limit() endpoints and WebSocket lifecycle channel.
• Multivariate enrichments: Collection events, associated events, selected-market support for lookups.
• New REST endpoints: get_api_limits(), get_balance_with_params(), get_order_group_for_subaccount(), and more.

Improvements

• Added #[serde(default)] to Series fields for resilience against API omissions.
• Corrected create_order_group endpoint path in API docs.
• Reduced WebSocket log noise (ping events no longer logged at info level).

Breaking Changes

• CommunicationData enum gained a new QuoteExecuted variant — exhaustive match arms will need updating.
• Version bump from 0.2.0 to 0.3.0.
