We are working! Please note that the latest version of BioBlender is always the one releases on GitHub.
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.
Drop us a line if you are willing to collaborate!
