I know it's a bit old topic but with a bit non-linear time for work Rev 5 of CoG is getting very close
Actually last two bugs are standing on my way (maybe 3 if I want to be non-lazy this time)
After I will correct them (hopefully in one day) Rev 5 will be released to public
Changelog is avaiable at usual place
Forum is still standing as well with a bit changed style
That's all I guess...for now...
