Changes#
Version 1.1.2 (Latest)#
Major Features: - PyQt6 Migration: Complete migration from PyQt5 to PyQt6 for future compatibility - Python 3.13+ Support: Ensured compatibility with Python 3.13 and future versions - Advanced Curve Fitting: Implemented 7 mathematical models (Gaussian, Lorentzian, Linear, Exponential, Quadratic, Cubic, Error Function) - Curve Unscaling: New “Un” column for rescaling curves to match the range of other Y curves - Auto-Load Folders: Application automatically loads the first valid folder from recent folders list - Lazy Loading: Efficient folder scanning with progress indicators for large datasets - Recent Folders: Remembers recently opened folders for quick access - Data Caching: LRU cache system for improved performance with large datasets
Technical Improvements: - CI/CD Pipeline: Comprehensive GitHub Actions workflows with cross-platform testing - Code Quality: Pre-commit hooks, ruff linting, mypy type checking - Documentation: Comprehensive Sphinx documentation with API reference - Testing: 130 tests passing with 46% coverage (improved from 36%), automated testing on multiple Python versions - Performance: Optimized memory management and data loading - Multiple Selection Support: Enhanced table model to support multiple selections per row for advanced data processing - Tooltips: Added helpful tooltips for all checkbox columns (X, Y, I0, Un) explaining their purpose and selection rules
Bug Fixes: - Fixed matplotlib artist removal crashes - Improved folder view selection and auto-selection logic - Enhanced error handling and user feedback - Fixed PyQt6 API compatibility issues
API Changes: - Updated all Qt constants to use enum-based syntax - Moved QAction and QShortcut imports to QtGui - Replaced QDesktopWidget with QApplication.primaryScreen() - Updated QSettings constants to use enum-based format
