Feb 1, 2026February 2026 (2026-02) – ARUP-CAS/aiscr-webamcr focused on reliability, data integrity, and developer experience. Delivered two feature initiatives with concrete outcomes: 1) Documentation and Logging Improvements for Django Management Commands, including Docker usage guidance and enhanced logging across management commands; 2) Data Import Process Validation and Model Update Restrictions to enforce data integrity via FTP configuration checks and forbidding updates for select models. A targeted bug fix addressed method name inconsistencies in Django management commands to prevent runtime errors and improve maintainability. These changes enhance observability, reduce data import risk, and streamline deployment in containerized environments. Commits included: bea54dae1517bcaba19a6a1b06a5939822c705f9 and 1f1d40b242e43aa170b28952f266826d7975b9ce.

Jan 1, 2026January 2026 (Month: 2026-01) — Delivered targeted improvements across documentation, backend tooling, deployment, and code quality for ARUP-CAS/aiscr-webamcr. Key outcomes include clearer WebAMČR documentation structure with improved guidance for users and developers, expanded Django management commands for metadata management, thumbnail generation, and access snapshots, and significant deployment optimization via a multi-stage Docker build pipeline. A robust fix for Pian object retrieval prevents crashes when the initial object is missing, enhancing reliability. File upload handling was strengthened with better validation, permissions, and error reporting, complemented by developer-facing documentation. General code quality improvements included migrating variable declarations to let/const, along with license information updates to ensure policy compliance. Overall, these changes reduce time-to-value for end users, improve system reliability, and boost developer productivity and maintainability.
