v0.4.0

Release Notes

Summary

This release enhances task and graph management, improves thread safety and error handling.

Features

• Enable multiple consumers per task type by switching consumer storage from a single object to a list, requiring explicit consumer specification.
• Introduce a SimplePlanAdaptor and create_simple_planning_graph function to support a simplified planning workflow when no iterations are required.
• Extend the task notification interface by adding optional parameters and support for an additional BaseModel context in status updates.
• Add helper methods in the Task class, including an 'is_type' method and a new find_input_tasks method, to improve type verification and provenance retrieval.
• Improve handling of multiple graphs and allow selection of specific graphs within the dashboard.
• Improve TaskWorker by incorporating provenance-based user state management. This state will get automatically cleaned when the provenance leaves the graph.
• Support multiple sink workers in a single graph.

Bug Fixes

• Eliminated a race condition in the dispatcher when there were multiple outstanding notifications but no other work left in the graph
• Resolved a race condition in work publishing and provenance tracking by separating check and removal phases.
• Fix XML serialization issues by modifying list item conversion and implementing recursive sanitization to correctly handle various data types.

Documentation

• Add an "Example: Deep Research" section in the README with Docker Compose instructions and updated licensing details.
• Include a detailed command-line example for automatic prompt optimization

Tests

• Enhance InvokeTaskWorker tests by integrating a MockProvenanceTracker and MockGraph, disabling debug_mode when detected, and ensuring caching functionality is initialized.
