See https://github.com/qgis/QGIS-Enhancement-Proposals/issues/86 - Checking/unchecking a group doesn't change the check state of its children. A node is visible if and only if it is checked and all its parents too. - There is no more a semi-checked state for a group - Ctrl-clic on a unchecked group will check the group and all its descendants. - Ctrl-clic on a unchecked layer will check the lager and all its parents. - Ctrl-clic on a checked group will uncheck the group and all its descendants. - Ctrl-clic on a checked layer will uncheck the layer and all its parents. - Those actions are available in contextual menu items in the tree view. - Invisible layers because they or their parent(s) is unchecked are greyed out.
