Go and download now the newest version or read the changelog (and you can even do both!)
New features in this version:
Buttons to adjust the preview size for templates according to some standard web screen sizes
Templates system automatically generates required css and js files if they don't exist in a directory
Definable date format for each survey language
New setting for statistics charts to set font and font size. If set to auto the best possible font for a language is chosen. Also RTL languages are now properly reversed for chart display

Numerous bugs were fixed so this version should be very stable by now - give it a try!
