WARNING: Usage of versions lower than 0.10 (which may not even be released yet) is very much hit and miss. They might work, they might not. Getting them running is not even something I advise you to try. Please wait for 0.10.
Note that all old downloads have been removed due to obsoletion and general uselessness. These files are available by request, but I promise you, you don't want them.
