The only thing that is missing, relative to Spice, is "PTF".  That is 
due to a model compiler limit, which should get fixed this summer.

Initial conditions are mostly coded, but I wanted to get the release 
out and didn't have time to fully test it, so I claimed "unsupported" 
rather than wait any longer.  I have a heavy teaching load this 
semester, that put everything else on hold.

Do you have any test circuits using PTF that I can use for validation?

I am aware of other published models.  What gets implemented will be 
dependent on interest and funding.  The biggest problem with Spice 
models in untangling the spaghetti code.
