latest scad release is NOT the latest release.
go here : http://www.openscad.org/downloads.html

on the right click on: Development Snapshots
Takes you down to the part of the page with the ACTUAL latest releases.

Some cool new features that, as far as I can find out - just aren't listed. You have to meander through the manual untill you see: 'new in release 2016.*.*'
How I found out you could do a partial rotate extrude.

Must be some other stuff in there as well. I just haven't gone through the whole manual yet.
