Great, thanks for posting Syed!
I don't think there are any changes for v11.x in the samples. The official route for obtaining the samples is through Support or an SE.
Apologies for the lack of info in the API doc about how to obtain the samples. At the time the DLP Information Development team was producing the doc, the way of distributing the samples was still being determined. We'll fix that in the next release.
Thanks,
Steve
