Oct 1, 2025October 2025 monthly summary for mantidimaging focusing on stability, accuracy, and measurable user value. Delivered two primary work items with direct business impact: (1) fix for ImageStack shape attribute consistency to prevent shape-related errors and ensure reliable data handling; (2) enhancement of the fitting engine to expose quantitative metrics (RSS and Reduced RSS) in the GUI and export table for clearer assessment of fit quality. These changes improve reliability, data integrity, and decision support for users, while enabling easier maintenance and future enhancements.

Jul 1, 2025July 2025 MantidImaging monthly summary: Focused on reliability, cross-platform compatibility, and maintainability enhancements. Key features delivered include Cancel support for dataset loading; Windows type annotations improvements; Pathlib-based refactor across core modules for better type safety; extensive Pathlib compatibility across modules with corresponding test adjustments; and maintenance through dependency updates (Sphinx, PyData theme, requests, scikit-image) and Astropy upgrade. Major bugs fixed: stabilizing tests after refactor. Overall impact: improved responsiveness for large datasets, cross-platform stability, and reduced maintenance burden, enabling faster development and more reliable downstream analyses. Technologies/skills demonstrated: Pathlib and type-safety refactors, Windows type annotations, large-scale codebase modernization, test engineering, and dependency management.

28 Commits • 13 Features
Jun 1, 2025June 2025 for mantidimaging delivered user-guided export validation, expanded logging visibility, lifecycle refinements, and code-quality improvements that directly boost reliability and maintainability. Features implemented include RITS export step-size validation; a Logging Configuration Settings tab; and a Welcome Screen refactor to emit a closed signal. Reliability fixes addressed a RuntimeError in recolor_links when a layout is deleted, added a clear error when no parser matches, and corrected a data-loading log typo. Cross-cutting enhancements added comprehensive logging across core processes (e.g., COR fitting, reconstruction, minimisation), memory setup/startup message cleanup, and non-clean shutdown warnings with log links, plus UI wiring, type annotations, dead-code cleanup, and refined file display. Overall, these deliverables reduce user errors, accelerate troubleshooting, and improve maintainability for faster feature delivery and better developer velocity.
