why"model_diagnostics(M_,options_,oo_)"didn't work?

Hello all,
I used to type “model_diagnostics(M_,options_,oo_)” after running the model if it didn’t run successfully.
However, in recent days, it shows nothing after I type “model_diagnostics(M_,options_,oo_)”.

Is there something wrong with my Dynare??
Looking forward to your help.
Thanks in advance.

If you are using an older version of Dynare, if no obvious problems are detected, there is not output at all. Only more recent versions provide positive feedback.

Hi jpfeifer,
You are very helpful. Thank you so much for helping us at this forum. I am truly grateful.
I am using Dynare 4.4.2. Do I need to update it?
If I don’t need to, I don’t want to because I am afraid of some other problems come out.
Thank you again.

Unless you encounter one of the bugs noted at dynare.org/DynareWiki/KnownBugs, there is no reason to upgrade. But I would always recommend using the latest stable version.

OK,thank you for your help!
