This release exists only for beta testing purposes. It is not recomended to download the windows version, since it is only tested to work under WINE and not under any real windows systems.
The source code though, should compile and run normaly under any linux systems. So if you want the linux version, you can either wait for the normal release(which will include deb and rpm packages) or download this.
News about changes in this version will follow as soon as the final release comes out.
