Since the last release, we have fixed several minor issues, related to :

MLP calulation on surface and storage of data

EP calculation and handling of Field lines

Movie Export with EP and MLP surface

Also the Manual has been updated with some suggestions for a better use of BioBlender

We are also actively working to the version for Blender 2.8.
