While preparing everything for the development of Bforartists 2 i have cleaned up our server a bit. And deleted the old development versions of Bforartists 1 at the download page. They were just available for historical reasons. And it makes simply no sense to keep them online anymore. Bforartists 1 is in fact the old version now.
When you are in need of an old development version of Bforartists 1, then you have to compile it by yourself. The sourcecode can be found at Github. github.com/Bforartists/Bforartists/releases
