I am so pleased to get the first alpha of ChamelonOS out of the door for testing. See announcement on the home page and download information here. I think this release has to have alpha status as it is the first release and based off Unity RC2.
Although it’s an alpha I think it shows of LXSkins (the skins changing feature) perfectly well and is defintely stable enough to install and use and abuse. If you do try it, please leave me some feedback anywhere on this site or at the Unity Linux forum.
Future releases will be based off Unity 2010 final.
