Linux-BETA contains releases for various popular Linux platform. If a package for your platform is missing, drop me a note and I'll see what we can do.
Windows holds the releases for 64 bit and 32 bit Windows platforms. Currently Windows 7 and later are supported, although the older versions here will work fine on loder versions of Windows.
PreReleases are of interest for testers and translators. Drop me a line if you'd like to join the team.
OldFiles - as the name implies.
