I downloaded the new version (1.0.0RC2) and compared to the older version (0.9.10.56) when it generates the gcode for a simple object, in this case a ring the new version generated the support material on the outside of the ring utilizing the fast and medium configs with auto support from lulzbot.
This is after I cut the material away. It is a simple cutout (capital letter C) and worked fine with the older slic3r version.
Is there a way to adjust the slic3r settings so the support is interior and less noticable after being cut away.
Additional photos, C photo is old slic3r auto support config and the other shows the rectangular piece generated with auto support config on the new slic3r
