Month: 2025-10 – This period focused on delivering user-visible features, stabilizing test reliability, and hardening deployment. Key features delivered include conditional rendering of the Versions tab in the Hyrax file set edit view to hide the tab when versioning isn't supported, accompanied by a test to validate the behavior. Major bugs fixed include test stability improvements to prevent flaky failures from Sipity::Role.create and expanded ImportUrlJob tests to cover additional URL variations and Range headers. Deployment reliability was enhanced by docker-compose updates to ensure fcrepo starts before dependent services, reducing startup failures. In Hyku, gem upgrades were performed to enable Valkyrie/FileSet improvements via Hyrax updates (5.0-flexible branch) and Bulkrax 9.3.x compatibility. These efforts collectively improve user experience, reduce operational risk, and accelerate adoption of Valkyrie-backed workflows, demonstrating strong Ruby on Rails, testing, and deployment discipline.
