Any idea when 1.6.0 will be general available?
There is no timeline for this yet. Many people use FOG but very few help working on it. So things are going very slow at the moment. We’ll bring out a last 1.5.x release (1.5.10) to finish up that line and then the next will be a first 1.6 release (months down the road).
If you are keen to get InnoDB earlier you can follow the topic Goerge posted. From my point of view this should be possible in 1.5.x setups as well. But we won’t officially support this and don’t want to push out for a major change in the 1.5.x branch anymore.
