- Introduced multi-route functionality in the booking process, allowing users to add additional routes for general contracts.
- Updated the StepDocuments component to display onboarding documents automatically attached to bookings.
- Refactored Step4Route to manage extra routes and quantities dynamically.
- Improved Step8Review to reflect the new onboarding document handling and updated submission readiness checks.
- Added new API endpoints and services for managing contract route lines and rejecting bookings.
- Removed the allowConsolidation field from the booking model as it is now managed by the system.
