This is probably not an issue for most people, but it leads to incorrect file names for libraries which is a (small) problem for people packaging smooth (I am doing this for macports).
I think it should be set to 7, assuming the upcoming version is 0.9.7.
This is kind-of the same issue like in BoCA: https://github.com/enzo1982/BoCA/issues/8
In https://github.com/enzo1982/smooth/blob/master/Makefile-options, the REVISION is set to 0, although the latest shipped version is 0.9.6.
