The v8i GC Beta was released some 4 days ago. I have just installed it and so far no problems. If you want to get involved go to this link:

In addition I am told the BIM components with Architecture and Structure components and TriForma drawing extraction will be posted in the next few days. So by SG in SF we will have all those to use. Enjoy!
