A new v3 beta (version Nov-6-2012) is now available for download here: http://moi3d.com/beta.htm also ,linked to from the download page on the main web site.
Mac version should now work fine with the latest OSX system updates 10.8.2 and 10.7.5 without needing any other settings adjusted.
New DXF file format support for import and export - focused on curve entities like lines, polylines, arcs, circles, splines. Should help with data transfer to and from various 2D CAD programs. When exporting you can choose to export either a 2D projected view which will flatten the curves by a view projection, or to export the 3D curve data. It's saved as an AutoCAD 2000 version DXF file.
Updated closed surface skinning to do periodic closed surfaces - fixes problems with closed fillets, blends, and sweeps where the generated surface was not smooth at its closing seam area. One recent one reported here: http://moi3d.com/forum/index.php?webtag=MOI&msg=5376.1 which should now be smooth in the seam area where there was a crease happening previously.
Fixed a regression in the last geometry library update that was causing failures with analytic intersections between planes and cylinders and preventing some Booleans from working. Also fixed another regression that was messing up Inset as reported here: http://moi3d.com/forum/index.php?webtag=MOI&msg=5508.1
