A new version of the Product Wiget is shipped with Whymper V1. The architecture has been fully reviewed and better integrated with the Gravity framework. It is now possible to display single product occurrences (performances/matches/timeslots). The support for products coming from multiple sales channels has been improved and it is now fully functioning.
