Surrogate search with integer parameters

Reading the documentation for surrogate search it tells me there is an input "intcon" to specify which parameters should only take integer values.

When I try to use it, I get errors saying that I'm giving surrogateopt too many input arguments. Looking at the surrogateopt file, it indeed is missing the input intcon.

I have version 2019a. Is there something going on that I'm missing? Is intcon available in 2019b? I notice intcon is actually only available in GA, but my objective function is expensive to evaluate, so the surrogate method is much preferred.

intcon was introduced to surrogateopt in R2019b.

Thanks for that. How do you find out when components were introduced? The documentation says surrogateopt was introduced in R2018b, but thats all I can find.

The lst section of most of the entries in the documentations is always See also. Below this there is the information when the function was instroduced. Changes in the functions you can find in the release notes as already posted in my answer.
