Sorry that the purpose is not stated clearly in release notes.
Actually, we have many requests to tech support saying 'I connect 2x Kinect v2 sensors but iPi Recorder sees only one'. People just overlook notes about the limitation on the web site and in docs.
Now, iPi Recorder detects how many Kinects v2 are connected to a PC (in the list of hardware identified by OS). If more than one, then it displays a warning with the link to
docs about distributed recording.
So, it's just a matter of better issue resolving for users.
