I compiled it for Windows 32-bit (Dynamic Recompiler doesn´t work however). You can download it here:

But really, most of the changes have only been made to the Linux version of it (like a ROM browser, Rice Video Linux, changes to the Blight input plugin, etc)

In this build there´s Kaillera and some *minor* minor minor improvements.
