Highlights on this page

Thanks for your feedback


24 January 2017, We're pleased to present Fledermaus 7.7.3

Fledermaus exported BAGs inherited offsets compared to original data that created them. You are affected by this bug if you use BAGs as part of your overall delivery products. When BAGs were exported they had a cell center/edge offset. You are strongly recommended to review the BAGs produced with any recent previous version of Fledermaus. Before recreating your BAGs, you can test if the BAG created was affected by this bug. Please follow the next link to the Technical Note - Ensuring BAG import/export consistency.
