I just upgraded from 1.3.1 to 1.4. All went well, except that when I want to look at the submitted material (of which the number of submitted assignments is correct, i.e. equal to that before the upgrade), I get the message 'No students enrolled'.
However, when I look at the administration page where I could enroll students, the correct students are shown as being enrolled. So where did the link between the assignments and the students go?
