For the time being b 2 remains in Early Access.
With Early Access, initially intended was to find out whether server hardware and network software is stable and to learn ideas for possible additions.
Server hardware is stable -- with few players -- and network software appears stable as well except for a possible flight path prediction issue which I was not able to solve and left open.
Some ideas put forward are already added, like the free mouse look.
Other ideas like more "npc"s require network syncronisation implementation solutions I have not found yet. (The bear is attempted to be syncronised initially but then left "on his own" for each player.)
I feel more can be done to warrant a change in status but when this will be I don't know.
Enjoy b 2 meanwhile as you like
