Bug fixes: - Imported mesh regions/zones not being parsed. - Saving data in csv format - "Do not crop" mesh being cropped in 3D - Geometric factor recomputed after forward modelling - Can still add data to a survey even if reciprocals are present. Changes/Improvements: - Pseudo sections support buried electrodes - Improvement to difference regularized inversions. - Improvement to meshing in 3D for borehole surveys. - 3D mesh refinement stability improved. - Added volume calculation in the UI.
