In the course option the course menu and toolbar can already be configured to not be shown. There are scenarios however where the bread-crumb navigation in the course should also be removed. E.g. in the static course sites that in many cases contain only of a single page without any navigation at all.
A new option allows the removing of the bread crumb entirely. Of course this has drawbacks, e.g. closing of tools is not possible anymore. This must be taken into consideration when using this feature.
