Skype Room Systems v2 version 3.1.98.0 deployment kit is available for download from TechNet as of March 20th.

 

NOTE: Building an image with 3.1.98.0 and Windows 10 Version 1709 requires the addition of Win10 January Update KB4056892.  Also, a PS1 script is available on the TechNet site to more quickly build images.
