+  Support controlling the submit type for changes from Prolog]
++
+Similarly like the `submit_rule` there is now a `submit_type` predicate
+which returns the allowed submit type for a change. When the
+`submit_type` predicate is not provided in the `rules.pl` then the
+project default submit type is used for all changes of that project.
++
+Filtering the results of the `submit_type` is also supported in the
+same way like filtering the results of the `submit_rule`. Using a
+`submit_type_filter` predicate one can enforce a particular submit type
+from a parent project.
