v2.43.8

Fixed

• Build: Commit missing core/src/utils/logger.ts and related file changes that were breaking CI.

v2.43.5

Fixed

• Python SDK: fetch_order_book now works — fixed _compat_kwargs typo, added None placeholder for params positioning, and array response handling for range queries.
• Python SDK: Added dt field to OrderBook model (maps to datetime in API response).

v2.43.4

Fixed

• Docs: Add FetchOrderBookParams to GENERATED_SCHEMA_ORDER so the AST parser builds the schema from the interface. TYPE_REF_MAP alone was not enough — the generator also needs the schema order entry to enumerate properties as query params.

v2.43.3

Fixed

• Docs: Register FetchOrderBookParams in TYPE_REF_MAP so the OpenAPI generator emits side, since, until as query parameters on the fetchOrderBook endpoint.

v2.43.2

Fixed

• Docs: fetchOrderBook params (side, since, until) now appear in auto-generated API docs. Replaced Record<string, any> with typed FetchOrderBookParams interface so the OpenAPI generator can enumerate the properties.

v2.43.1

Fixed

• SDK: fetchOrderBook now correctly inserts a null placeholder for limit when only params is provided, ensuring params lands at args[2] for the hosted API.
• SDK: fetchOrderBook now handles array responses from range queries (since + until) instead of treating them as a single OrderBook.

What's Changed

• add MockExchange for offline development and testing by @mooncitydev in #107

• docs: include exchange in WebSocket examples by @999axel999 in #476

Full Changelog: v2.42.7f...v2.43.1f

v2.43.0

Added

• fetchOrderBook: Historical order book support via params.since and params.until. CCXT-compatible signature (outcomeId, limit?, params?) across all exchanges and SDK.
  • { since } — single L2 snapshot at or before the given timestamp (hosted API only, backed by ClickHouse archive).
  • { since, until } — array of fully reconstructed L2 books from tick-level deltas. Default 100 snapshots, max 1000.
  • Full reconstruction for all 4 archived venues: Polymarket (absolute deltas), Kalshi (additive deltas), Limitless, Opinion.
• OrderBook.datetime: ISO 8601 datetime field on the OrderBook type (CCXT-compatible).

Changed

• fetchOrderBook signature widened from (outcomeId, side?) to (outcomeId, limit?, params?). Backwards compatible — side moved to params.side. All 14 exchange implementations, Router, and SDK updated.
• SDK fetchOrderBook return type widened to OrderBook | OrderBook[] (array when since + until are both provided).
