Core Engine Fixes
Named Output Pins System Overhaul
- Fixed connection deserialization: Resolved critical issue where graphs using @outputs: docstring annotations failed to execute due to ambiguous pin name resolution
- Added direction-aware pin lookup: Implemented get_pin_by_name_and_direction() method in Node class for precise pin identification during connection creation
- Enhanced pin update algorithm: Replaced naive pin removal/recreation with intelligent position-based matching that preserves connections during docstring edits
- Connection preservation: Pin renaming operations now maintain all existing connections, types, and visual properties
Code Editor Integration Fixes
- CommandHistory method calls: Fixed AttributeError in CodeEditorDialog where incorrect push() calls were replaced with proper execute_command() method
- Pin type synchronization: Function signature type changes now correctly update both pin.pin_type property and visual labels
- Real-time updates: Pin labels refresh automatically when function annotations are modified (e.g., Data (str) to Data (int))
Pin Display Enhancements
- Type visibility controls: Added Settings dialog checkbox for toggling pin type display with dynamic refresh capability
- Label formatting: Pin labels can show/hide type information (e.g., length (int)) based on user preference
- Settings persistence: show_pin_types setting saved with default value true
Build System Improvements
- Script error fixes: Corrected syntax errors in batch files that caused build failures
- Automated workflow: Removed interactive prompts to enable automated builds
- Build organization: All artifacts now organized into builds/ directory structure
- PowerShell compatibility: Fixed Python runtime download command and updated deprecated Nuitka console options
- Artifact management: Added builds/ to .gitignore to prevent accidental commits
Example Graph Updates
- Named pin migration: Updated all example graphs with proper @outputs: annotations
- Connection fixes: Corrected pin names in weather_data_processor.md, nvidia_gpu_computer_vision_pipeline.md, and recipe_nutrition_calculator.md
- File dialog memory: Added folder memory functionality to remember last used directory
- Example cleanup: Removed 10 outdated example files that lacked named output pin support
Documentation Restructure
- Organized hierarchy: Restructured docs into logical categories (developer_guide, implementation, issues, project, reference, user_guide)
- Technical specifications: Added Epic 3.4 documentation and pin type visibility enhancement specifications
- Development guides: Enhanced testing documentation and implementation notes
Technical Improvements
- Backward compatibility: All changes maintain compatibility with existing graphs
- Error handling: Enhanced error handling in execution pipeline and connection resolution
- Code organization: Improved module structure and separation of concerns
Known Issues
- Python virtual environment configuration requires manual setup
- Environment switching workflow needs refinement
- Some build script edge cases on specific Windows configurations
