The official version number is printed to the logfile (v17.0).
Note, mver is used for internal purposes only (e.g. compatability of makenek)

It's on our list to support the full sress-formulation for PnPn.

Anyway, yes even in v17.0 we disabled certain features for PnPn as some combinations are not yet supported or well tested. It's very likely that some of the might work out of the box but we offically we don't support them (at least for now).
