   o added optimization using Rsolnp, which can be invoked by using 
     method="rsolnp" in calling fit on (dep-)mix objects. Note that 
     this is meant for fitting models with additional constraints. 
     Method="rsolnp" is now the default when fitting constrained

   o added multinomial models with identity link for transition and prior 
     probabilities. These are now the default when no covariates are 
     present. 
 
   o added bounds and constraints for multinomial identity models such
-    that these constraints are satisfied when fitting models with 
-    method="rsolnp" or "donlp". Also, variance and sd parameters in

   o added option to generate starting values as part of the EM 
     algorithm. 
 
+  o fixed a bug in multinomial response models with n>1; the response for

+	observed responses for each category; the loglikelihood for these

+	incorrect; note that such models may lead to some numerical
