The main new feature is the improved export dialog. When you export, you will have at hand the different options: how to export, name of your export, which format to choose and last but not least, the file size.
We also improved the settings (available via the menu button). You can now specify the default enhancement that must be applied to the scans and the quality of the images created by Genius Scan (the higher the quality, the more space it takes and the slower it will export on a 3G network). It also shows you the amount of storage used by Genius Scan.
We also improved the help section and fixed tons of minor bugs. Enjoy and let us know how you like it!
