This release doesn't add much in the way of new features to the application itself, just the ability to save displayed images in formats other than Windows Bitmap. However, the big change is that it has been ported to the Qt framework so it can now run under Linux as well as Windows.
Additionally, there are
.msi installable packages available for download for Debian-based Linux distributions and Windows respectively.
