Oo_.dr.ys vs oo_.steady_state


In the new version I see that one can find two steady states that are stored. One in oo_.dr.ys and another in oo_.steady_state.

I am estimating a model, after the estimation where is the correct steady state that has to be used (the one that depends on the newly estimated parameters)
is it in oo_.dr.ys or oo_.steady_state? what is the difference between these two objects?

Thank you in advance for your help!
