   o The Changes for each release (in the NEWS file) is now split into two 
-    sections: Major and Minor changes

+  o Added several examples on the ?responses page (Poisson change point
+    model, similar model with a single multinomial response) and the 
+    ?depmix page (model for S&P 500 returns; thanks to Chen Haibo for
+    sending this).

   Minor changes
   
   o Corrected a typo in the vignette in Equation 1; the first occurrence

+  o Added a sensible error message when the data contains missings (depmixS4 
+    can not handle missing data yet). 
+
+  o Fixed a bug in the relative stopping criterion for EM (which resulted 
+    in immediate indication of convergence for positive log likelihoods; 
+    thanks to Chen Haibo for sending the S&P 500 example which brought out
+    this problem).
+
+  o Function forwardbackward now has a useC argument to determine whether 
+    C code is used, the default, or not (the R code is mostly left in place
+    for easy debugging). 
+   
+  o Added a fix for models without covariates/intercepts. In responseGLM 
+    and responseMVN the function setpars now exits when length(value) == 0. 
+    In setpars.depmix, a check is added whether npar > 0.

 Changes in depmixS4 version 1.0-4
 
   o Added examples of the use of ntimes argument on ?depmix and ?fit
