Changelog

This is a public changelog focused on user-visible behavior (endpoints, tools, and workflows). It intentionally omits deployment/internal operational details.

0.4.7 (2026-01-15)

Added

• MCP JSON-RPC 2.0 at POST /mcp (initialize, tools/list, tools/call, ping).
• Tool discovery: GET /mcp/tools/list.
• MCP tools: health, presets, schema, validation/hash, batch generation, normalization, funding simulation, venue details, cache stats.

Changed

• MCP tool responses align with the standard MCP content format.
• Tool schemas include explicit JSON Schema inputSchema for clients.

0.4.6 (2026-01-14)

Added

• Batch generation via MCP: generate_dataset.
• Async job processing for long-running batch workloads.

Changed

• Documentation updated to match the batch generation workflow.

Fixed

• Reduced timeout incidence for longer batch jobs through async processing improvements.

0.4.5 (2026-01-13)

Added

• Authentication improvements (machine-to-machine support).
• Improved health checks: GET /mcp/health.
• Data validation: Additional validation capabilities for output quality checks.

Changed

• Health check behavior tuned for monitoring use cases.

Fixed

• Stability and correctness fixes.

0.4.1 (2025-12-22)

Added

• Additional venue models (including CME and SGX).
• MCP Normalization Endpoint: POST /mcp/normalize for normalizing events from synthetic, HyperLiquid, Binance, CME, and SGX sources.
• MCP Funding Simulation: POST /mcp/simulate_funding_regime for simulating funding rates across all 6 exchanges.
• MCP Venue Discovery: GET /mcp/venues/{exchange} for venue details and supported features.
• MCP Config Schema: GET /mcp/config/schema for JSON Schema export of SimulationManifest.
• MCP Config Validation: POST /mcp/config/validate for validating configs and computing hashes.
• MCP Presets Endpoint: GET /mcp/presets for listing available preset configurations.
• MCP Health Endpoint: GET /mcp/health for MCP-specific health checks.

Changed

• Updated API documentation to reflect actual endpoint signatures and response schemas.
• Fixed batch generation response schema (status: "completed", download_url, row_count).
• Fixed live stream parameters (removed non-existent preset and rate_multiplier, added seed).
• Updated funding model documentation with correct file structure, CME/SGX support.
• Fixed HyperLiquid documentation (8h default interval, ±4% hard cap, velocity range 0.3-2.5x).

Fixed

• Documentation now accurately reflects implemented code for all MCP endpoints.
• Documentation fixes and corrections.

0.4.0 (2025-11-29)

0.3.0 (2025-11-28)

Added

• Dual-driver architecture for batch + streaming.
• Live streaming (SSE): GET /stream/live.
• Batch Endpoint: POST /data/generate for triggering dataset creation.
• Schemas for type-safe API interactions.

Changed

• Architecture documentation updated.

0.2.0 (2025-11-28)

Added

• Venue-specific funding models.
• Microstructure features including burst behavior and network staleness simulation.

0.1.0 (2025-11-27)

Added

• Core HyperSynthReactor generator.
