Please revert to old version until we write full documentation.
All this features are splited as a new extension (yes they are free) as many people requested that they want to disable some features.
Inconvenience regretted.
Thank you for such a beautiful plugin and sticking with your principles to keep it free, even many of us would be ready to pay for it. It has been the most awesome Q&A plugin so far!!!
I hope to see you success, but releasing non documented alpha versions as fixes is just not very smart.
I have reverted the last release..
