More realistic calculation of vortices at the blades and therefore real airfoil parameters can be used now (not to be mixed up with the vortex ring state which is still not simulated), ground effect is now continuous e. g. at buildings, calculating of the rotor in more than 4 directions, better documentation of the airfoil parameters.
