Nobody knows it. Many features are still in the making but it might be that a new "bug-free" version will appear soon with new updates coming later.
JCL said "the core engine is finished". But the tools (e.g. level compiler) need some work. The static shadows still produce errors with static meshes as an example.
I want to use shaders and other commercial features.... to do that I need to upgrade but I guess that now I will have to wait for the release of the full version of A7...
