v2.3.0

Features

• Outcome Shorthand for Trading: You can now pass a MarketOutcome object directly to createOrder (TS) or create_order (Python) instead of manually specifying marketId and outcomeId.
• marketId in MarketOutcome: Market outcome objects now include the marketId they belong to, enabling the new shorthand functionality and better data traceability.

Changed

• Improved Type Safety: Enhanced input validation for order creation to ensure consistent behavior across different parameter combinations.
• Documentation & Examples: Updated trading examples to demonstrate the new recommended shorthand pattern.

• Developer Experience: Added npm run dev command to support streamlined local development with automatic rebuilding and sidecar management.

Documentation

• Architecture Overview: Added a comprehensive ARCHITECTURE.md guide explaining the project's internal structure and core principles.
• Exchange Contribution Guide: Created core/ADDING_AN_EXCHANGE.md to provide clear instructions for developers looking to integrate new prediction markets.
• Improved Onboarding: Updated CONTRIBUTING.md with detailed monorepo structure and prerequisites. Added .env.example to simplify local environment setup.

v2.1.3

Features

• Polymarket Performance Optimization:
  • Implemented preWarmMarket in the PolymarketExchange class. This allows for caching market metadata (such as tokenAddress and negRisk status) before placing orders, significantly reducing latency during critical execution moments.
  • Streamlined the createOrder workflow by removing redundant inferTickSize logic and delegating default handling to the Polymarket SDK.
• API Enhancements: Added support for the negRisk parameter in CreateOrderParams, enabling more granular control over order types on Polymarket. <-- not in openapi schema yet
• Developer Experience: Added a new benchmarking script core/scripts/test-order-speed.ts for measuring end-to-end order placement latency.

v2.1.2

Fixed

• Kalshi Pagination: Implemented recursive pagination for Kalshi search, enabling the retrieval of up to 10,000 results per query (previously hard-limited to 200).
• Kalshi 'All' Status: Enhanced the 'all' status filter to simultaneously fetch from open, closed, and settled endpoints, providing a truly comprehensive view of Kalshi events.
• Polymarket Status Verification: Added strict client-side status verification for Polymarket search to prevent "active" events from leaking into "closed" queries, ensuring high search precision.
• Limitless Status Filtering: Standardized status filtering for Limitless to correctly distinguish between active, expired, and resolved markets within search results.

Changed

• Unified Status Terminology: Introduced 'inactive' as a universal alias for 'closed' across all exchange methods to provide a more intuitive API for non-binary market states.
• Improved Documentation: Enriched JSDoc metadata for fetchMarkets and fetchEvents with exchange-specific implementation details and usage examples.

v2.1.1

Changed

• Increased Default Limits: The default limit for fetching markets and events has been increased to 10,000 results across all exchanges (Polymarket, Kalshi, Limitless) to provide more comprehensive search results by default.
• Polymarket Search Optimization: Migrated fetchEvents search to use the high-performance Gamma public-search endpoint with parallel pagination, significantly improving discovery for high-volume markets.
• OpenAPI Specification: Updated openapi.yaml to reflect the new default limit of 10,000 for market and event queries.

Added

• CI/CD Automation: Integrated automated GitHub release creation and unified publishing logic in publish.yml.
• Search Verification Tooling: Added core/verify_search.ts script for easy testing and verification of search performance and accuracy.
• Improved Metadata: Updated readme.md with cross-linked documentation and refreshed project statistics.

Fixed

• Workflow Reliability: Resolved YAML syntax errors in GitHub Actions and removed redundant scripts to streamline the deployment process.
