Pre-release version
This is a pre-release version, which means that the software is still not 100% tested, and might change often until reaching version 1.0.
For now, no licensing or payment system is set up, so the app is free to download until version 1.0 is released.
Windows 64-bit zip

Other platforms:
Linux: Very soon! Everything's functional but need to figure out the best way to deploy for maximum compatibility.
Mac OS X: Probably not. But instructions for unsupported running of the app using something like Porting Kit might be added in the future.
