Dear Dr. Tieken, 

The first volume of the "Newari version" of the Nāṭyaśāstra was published in 2015. Here https://www.exoticindiaart.com/book/details/natyasastra-of-muni-bharata-critical-edition-vol-i-nba075/ one can also give a look to the foreword, introduction and ToC.
I can't find mention of further volumes. The IGNCA website might be the right place to search. 

Best wishes, 
Gaia Pintucci

​Dear List members, in a blog post Sugyan Kumar Mahanty mentions a project by Prof. Kamalesh Dutta Tripathy of editing a version of the NŚ based on manuscripts from Nepal in Newari script. Can anyone tell me what has come out of this project.
With kind regards, Herman
