CHANGELOG.rst

 * The lesson documentations tab was displayed on overviews for persons who are not teachers.
 * Teachers weren't able to edit personal notes of their students in the person overview.
+* The actions to mark absences as excused in the personal notes table also marked personal notes as excused which are not absences.
+* The delete action in the personal notes table really deleted the items instead of just resetting them to default values.
