Best DXF file version for Simple Trace

General Discussion

Can anyone shed any light on which DXF version is best for simple trace to interpret?
Seems R32 - 2018 is the latest version but a lot of apps use R3,R14 or R15 or does it not really matter?

A conclusive answer would be useful.

R13 or R14 is best
