## [0.1.1] - 2025-07-20

### Added
- Enhanced Python bridge with stored object resolution
- Fixed DSPy LM configuration issue where "stored.default_lm" wasn't being resolved
- DSPy examples for Question Answering, Chain of Thought, and Code Generation
- Model registry system for managing LLM provider prefixes (e.g., "gemini/")
- Configuration system for examples using simple Elixir config files
- Adapter comparison examples showing EnhancedPython vs GRPCPython
- Simulated streaming demonstrations for better UX
- Comprehensive debugging tools for DSPy integration
- Tool Bridge specifications for Elixir-Python RPC communication
- Documentation for stored object resolution and debugging DSPy integration

### Changed
- Enhanced bridge now properly resolves stored references in both args and kwargs
- DSPex.LM.configure now uses model registry for provider prefixes
- Improved error messages and debugging output

### Fixed
- "No LM is loaded" error when using DSPy modules
- Stored object references (e.g., "stored.default_lm") not being resolved to actual objects
- Model configuration requiring manual "gemini/" prefix addition
- Config file path issues when running from different directories
- Result extraction paths for DSPy Prediction objects
