Nov 1, 2025During November 2025, the SCPCA portal project delivered meaningful cleanup, docs improvements, and UI/UX refinements that strengthen maintainability and business value. Key features delivered include code cleanup removing obsolete safeguards around sample computed file downloads, and docs URL utilities with UI integration to ensure reliable ScPCA docs linking. A major architectural improvement was the Dataset UI format handling refactor, moving format logic to MyDatasetContext, which stabilizes format changes and default formats. Additional enhancements include SPATIAL_SPACERANGER support in getReadable and targeted UI tweaks (loading state for dataset downloads) that improve user experience. This period also included bug fixes and quality work: test value adjustments, TypeError fix in ProjectSamplesTableOptionsHeader, a dataset summary typo fix, pre-commit hook execution fix, and broader UI polish to reduce edge-case errors.

Oct 1, 2025October 2025 monthly summary for AlexsLemonade/scpca-portal focused on performance and data integrity improvements to dataset format validation. Implemented an early return when the new dataset format matches the original to avoid unnecessary processing, and centralized validation logic by removing validate_format from the serializer and moving format-change handling into the DatasetViewSet update path. Enforced safeguards to disallow changes for datasets with existing data or in processing state. Updated tests to align with new validation rules across serializer and views. These changes reduce processing time, improve data integrity, and simplify future maintenance.
