Neuromantic V1.3.1

OK, a slight update on V1.3.0 is now available. This version primarily fixes a bug to do with not always being able to select segments in the 3D window, as well as a few graphical issues related to altering the Z amplification. A minor memory leak has also been removed from file loading.

Finally, the minimum and maximum levels of magnification available in the 2D view have been expanded to 3.33% and 3000%. The previous max of 1600% was a little low when editing metric reconstructions.
