Whats new in this release? Well to start with we now have Wallbase.cc Authentication! so you can access favorites or NSFW. This version requires .NET 4.0, you probably already have it, but if you don't it's a free and easy download from Microsoft.
Pulse can bet set to start on Windows startup now too.
The Wallpaper setter has settings now, so you can change the background color of the desktop and the Picture Position (Tile/Center/Fill/etc...)
I've switched to Windows Forms instead of WPF because I am slowly working on Mac OSX compatability.
