For the batch stitching feature, we will especially develop a full-featured batch stitching software called Easypano Batch Wizard. We did plan to develop batch stitching in 3.0, but as more and more related features suggested by our beta testers, we decided to make another application, which will make batch stitching more easy-to-use and powerful. And surely it will not be a free upgrade one any more. Hope you can understand our decision.
