You can't postpone it for longer... we can't wait forever for the 100% bug free software... everyone knows it will have bugs for a while.
It doesn't make more sence... it seems that the render engine is working in some degree better than the beta today.. so let us play with it.. We understand it is broken here and there "just release it with a big warning for the unattended users" We'll understand the crashes.. we just need the new overdue bug fixes!
Releasing it broken today won't cause more damages than postponing it for weeks.
It will even be a good PR... You can even say... we trust on you to test our software !
