September 2025 focused on delivering and stabilizing the Moodle mod_booking module, expanding multi-booking workflows, strengthening approvals and calendar interoperability, and improving code quality. Delivered the multi-bookings flow from unfinished scaffolding to finished variant, introduced the 'previously booked' status, and tightened booking confirmation rights for admins/teachers; added tests covering end-to-end scenarios. Implemented approver/deputy view filtering, dynamic labels for booking-related UI, ICS calendar improvements with enhanced VEVENT handling, and comprehensive PHPUnit tests. Achieved code quality enhancements (linting, codechecker, PHPDoc fixes) and reliability fixes (integer user IDs, test isolation) to reduce manual work and improve data correctness.

August 2025 highlights for Wunderbyte-GmbH/moodle-mod_booking: Delivered major features and fixes across the booking flow, focusing on reliability and operator efficiency. Key bug fixes addressed booking extension checks, waiting list processing, and JSON handling during unenrol actions, while verifying extension enablement during confirmations. Booking confirmation workflow was enhanced with a refactored capability check, UI/table improvements, and new plugin settings to support trainer/supervisor scenarios. A new UI control to deny a booking answer was introduced, and code quality improvements accompanied by broader test coverage. Data-model refinements supported multi-confirmation scenarios by converting certain fields to arrays, and tests were expanded to cover booking_answer, trainer/supervisor confirmations, and edge cases. Additionally, course ID sourcing was corrected to use the booking settings instance, and tests were gated by plugin availability. These changes reduce live-risk, improve business value for admins and approvers, and strengthen long-term maintainability of the booking module.
