Fixed:

• Bug 3153690 : Error while scanning path with a "," or ";"
• Fixed UI for empty folder

Added:

• Totaly new draw engine (WPF). Faster and more powerfull. Defined as a plugin, which requires ".Net framework" version 3.5 SP1 or higher. Original draw engine ("basic engine") is still available.
• WPF draw engine : Zoom feature.
• WPF draw engine : Full "fluid" rotation, using slider or mouse directly.
• WPF draw engine : auto hide too small folders, in order to speed up the build of the graph.
• WPF draw engine : New Print feature (in File menu).
• New "native" scan engine on Windows : faster and more accurate (up to 6 times faster).
• "Drag & drop" capable (from Windows explorer)
• Auto check (after startup) if a new version is available. Check can be done manually via the "Help" menu. Auto check can be disabled in the Options menu.
• Partially compatible with Linux and Mac (basic draw engine only), thanks to Mono (http://www.mono-project.com).

Improved: 

• Design refactored, mostly with the WPF draw engine.

Fixed:

• Bug on "Text Density" : value loaded from a previous saved state was wrong.
• Wrong message when folder deletion failed.
• Some minor bugs...

Added:

• New warning messages when scan errors occured.
• New "image rotation" capability (you can rotate the graph as you want).
• New "text density" setting (you can change the text density in real time).
• New tooltip available when the mouse is hovered a directory.
• Count the number of files in a directory (see the "Directory Details" form).
• New commande line argument to set output image size.

Improved: 

•  Better resize mode (preview during resize, real redraw when resize finished)
• Asynchronous draw for complicated graphs (which take a long time to draw), to avoid application freeze.
• Main window state is memorized on exit (or the size if the window is not maximized).
• Performance improvements

Fixed:

• Bug 2505755 ("Wrong Image saved when run from CLI")
• Some minor bugs...
