# Release 539 - May 2024

# New features

  • Supplement tickets for cargo like bicycles or strollers: A supplement ticket allows a Traveler to take a Bicycle or Stroller onto the bus or train. The ticket can only be used as proof of payment to the inspector and cannot be validated since the number of travelers on a supplement ticket is always 0.
  • Group tickets with different pricing options for specific group sizes of up to 10 travelers. The number of adults & children are stored in the UIC barcode.
  • Tap Response (MMI) messageMMI messages can now contain the number of travelers and product name if needed.
  • Support for different fraud detection profiles. Product definitions can be linked to specific profiles. Existing products will be linked to the default profile.

Please see our API migration guide for using these features in your products and tickets.
