December 2025 focused on delivering admin workflow enhancements for holiday management, strengthening multi-domain data reliability, and aligning API and release tooling with the 18.0.0 cycle. Key outcomes include holiday import tooling (year and country) via ext-calendar and spatie/holidays, admin controls to mark closed days as public holidays, and user-facing warnings when holidays aren’t configured for current/upcoming years. Data fixtures across all domains were hardened to prevent domain-related warnings and preserve domain IDs, while withdrawal deadline logic was refined to always land on a valid business day. The admin UI was refreshed by regenerating Tailwind admin styles, and GraphQL API consistency was improved through schema regeneration and frontend-api packaging improvements. These changes reduce operational risk, improve data integrity, and accelerate onboarding for new holiday-related workflows and multi-domain configurations.
