Version 4.0 adds the ability to analyze networks, not just raster grids. We have overhauled the code to increase speed, use memory more efficiently, and allow parallel processing on Mac and Linux systems. (Parallel processing is currently limited to pairwise mode, but we are working to extend this to other cases.) Circuitscape now auto-detects whether focal points or regions are used. The user interface has been reorganized and we've added a console window. The user guide can be accessed via the Help menu. We would appreciate feedback and bug reports.
Mac OS X 10.9 and higher is supported, 10.6 and earlier is not. We have not yet tested on 10.7 or 10.8.
