+## [2.41.1] - 2026-05-15
+
+### Added
+
+- **Docs**: Watch methods (`watchOrderBook`, `watchOrderBooks`, `watchAllOrderBooks`, `watchTrades`, `watchAddress`) now show WebSocket transport documentation with `ws://` / `wss://` URLs, subscribe/unsubscribe protocol, and JSON message examples. Auto-generated by the OpenAPI generator.
+- **SDK (TypeScript + Python)**: `watchAllOrderBooks()` / `watch_all_order_books()` — renamed from `firehose()`. Streams all orderbook updates across venues with optional venue filter. `firehose()` kept as deprecated alias.
+
+### Fixed
+
+- **Docs**: Watch methods previously showed as HTTP POST endpoints (`curl --request POST`). Now correctly documented as WebSocket endpoints with connection URLs for both local sidecar and hosted API.
