+issueNumber: MDL-83479
+notes:
+  core_backup:
+    - message: >-
+        Added several hooks to the restore process to 1) Hook to allow extra settings to be defined for the course
+        restore process. 2) Hook to allow adding extra fields to the copy course form. 3) Hook used by
+        copy_helper::process_formdata() to expand the list of required fields. 4) Hook used to allow interaction with
+        the copy task, before the actual task execution takes place.
+        
+        Other changes include 1) base_task::add_setting() is now public to allow hook callbacks to add settings.
+        2) Settings are now added to the data sent to the course_restored event.
+      type: improved
