Hey @sergey.vasiliev welcome to the community site.
You're right, the latest release of n10s included an update of the RDF parser that implements the name change (As you know the RDF-star community&editors decided to remove the original asterisk in the name in favour of a spelled form of the word star).
-> All this to say that the type you have to use now is: Turtle-star (that exact syntax).
Thanks for the heads up, we'll update the documentation.
Enjoy using n10s and share your experience with the community here!
