Next release (alpha v0.00.05) is finally available for download at www.radiumrenderer.com
If you’ve tested previous releases, I strongly recommend you read the release notes (link in download section), there are quite a few changes.
If you’ve not tested Radium before, read the installation instructions carefully and I strongly recommend you read radium_gui.htm (can be found in radium/doc once you’ve installed).
I’ve also created a forum (no posts yet, even by me ;)). This is primarily for bug reports right now.
Any problems, please let me know by PM or on this thread
