5.0 will be releasing soon. I can’t say exactly when, but I can say it’s quite soon indeed.
5.0 is far and away ahead of 5.0EA in terms of features. Some say performance is better too but I haven’t really compared the two in that aspect.
Given how old the base of 5.0EA is at this point and how soon 5.0 will see its full release, I don’t think we’ll be seeing any more preview releases for 5.0EA. I can understand some frustration if you started or moved development over to 5.0EA, but that wasn’t why it was released. As others have said, it wasn’t meant for production work, it was meant to be a means to gather feedback from real world users.
It’s not a long wait now, so hold strong
