 #. Incorporates an option inside the tasks stage configurations that allows to automatically set a state to the tasks when they are moved to these stages.
 #. Re-incorporate the field is_closed in the tasks, under the label "Folded in kanban"
+#. Subtasks are created visible in the project's kanban view by default (display_in_project = True).
