April 2026 — Major frontend uplift for osbuild image-builder-frontend. Delivered a comprehensive Wizard/Review UI overhaul with a componentized architecture, including migrating ImageOutput to ImageOverview, and introducing new sections and wrappers. Expanded advanced settings to cover kernel, services, firewall, users, firstboot, plus timezone/locale/hostname, and added a target environment hook for cleaner separation of private/public/misc configurations. Implemented new UI cards (Content, Repeatable Build, Registration, Security) to improve configuration visibility and governance. Added derived selectors for FS customizations and a reusable FlexColumn layout component to standardize UI. Strengthened testing with unit tests for repository payload generation, Playwright helpers for Content Sources, repository selection/edit tests, and a shared Redux test store; plus durable Playwright tests using localStorage to dismiss modals and cleanup of legacy tests. Overall, the work increases configuration fidelity, user experience, test reliability, and compliance visibility, enabling faster and safer release cycles.

September 2025: Delivered OpenSCAP integration for RHEL10 in the image-builder frontend, exposing OpenSCAP profiles in the wizard and removing a restrictive conditional to make options visible. Strengthened stability and maintainability with internal tooling improvements: reduced test flakiness by wrapping rendering in waitFor, updated API typings for content sources, and upgraded TypeScript lint tooling and peer dependencies. Fixed critical behavior: first-boot systemd service is preserved during the wizard flow. Result: faster, compliant image builds with fewer flaky tests and a more maintainable frontend stack.
