A showstopper bug from Blender made it necessary to release an updated version. In Bforartists 2 Version 2.9.2 you can load the industry compatible keymap again. And it comes with four little last minute adjustments.
Sorry for the inconvenience. We do our best to make our changes at Bforartists as stable as possible. But we have unfortunately no influence of the changes that comes from Blender.
