Feb 1, 2026February 2026: Strengthened safety and reliability in the scpca-portal by implementing read-only safeguards in DatasetProjectSummary. The Remove All action is now disabled/hidden when readOnly is true, preventing destructive operations for read-only users. This change improves data integrity, reduces risk of accidental deletions, and clarifies permission boundaries. No new features released; primary focus was stability, safety, and maintainability.

Apr 1, 2025April 2025 monthly summary for AlexsLemonade/scpca-portal focused on improving data documentation, front-end readiness, code quality, and environment reliability. Key features delivered include dataset README templates and initial readmes with an HTML dataset summary and readme hash calculation, along with dataset.get_samples. A React frontend was initialized and production code was cleaned of console statements. CI/Pre-commit tooling was upgraded, and linting/formatting improvements (Black, Flake8 considerations) were implemented to raise code quality gates. Environment defaults were hardened with AWS region defaults, clearer network naming, and removal of mapped AWS volumes to simplify deployments. Additional improvements encompassed template location fixes, multiplexed check corrections, and consolidation of command formatting post-execution. Documentation and tests were enhanced with size-related README details and more specific content, improving maintainability and onboarding.

Dec 1, 2024December 2024 performance summary for AlexsLemonade/scpca-portal: Delivered auditable token-based download tracking and a performance-oriented refactor of S3 sync to efficiently handle large file sets. Implemented TokenDownload model with a DB migration and enhanced ComputedFile logging, including metadata_only and portal_metadata_only flags and strict project/sample linkage to ensure data integrity during tokenized downloads. Optimized download_input_files by grouping files by the immediate parent directory (or higher-level directory for deeply nested files) and performing per-group sync, significantly reducing AWS S3 commands and improving throughput. Included metadata attributes, variable scoping improvements, and code quality refinements (linting) to stabilize the codebase. These changes improve traceability, compliance, and operational efficiency of download workflows.
