Fixed: layer parenting discards the weights on the parent, and it’s not an undoable action.
Fixed: toggling some UI options in “Set Weights” tab produced a python error;
Added: group layers (those that have child layers) will now only show “mask” in influences, as this is the only option that is editable in a group layer;
Added: various UI improvements for license error handling. Consider updating to latest license server as well.
