Which Osclass software version is the real deal?

Hello to the community!
I was hoping that someone could enlighten me about the Osclass project.
I am researching and deciding if this product suits my needs.
My understanding is this product is open source and used to be maintained by osclass.org.
Who took over the project? There appears to be many versions/forks of the original project.
Which fork is the most supported by developers and users?
Does plugins and themes work interchangeably between the different forks?
Why so many forks?
I’m confused…please help ???

There are only two active version right now, one at GitHub.com/mindstellar/Osclass and other maintained by osclasspoint.
One is developed openly and another one behind the door. Choose what you like
