+#### Added
+
+- The question backup API has been improved to only include questions that are actually used or owned by backed up activities.
+  Any activities that use question references should be supported automatically. Activities that use *question set references* (for example, random quiz questions) need to add a call to `backup_question_set_reference_trait::annotate_set_reference_bank_entries()` alongside the call to `backup_question_set_reference_trait::add_question_set_references()` in their backup step. See `backup_quiz_activity_structure_step::define_structure()` for an example.

+
+#### Changed
+
+- `core_question_search_shared_banks` will now search all question banks, not just those outside the current course.
+  This makes the service usable in cases outside of the current "Switch banks" UI, which require searching all banks on the site.
+  It also makes the autocomplete in the "Switch banks" UI more consistent, as it was previously excluding some of the banks listed in the UI (Question banks in this course), but not others (Recently viewed question banks).
+  This change has also adds a 'requiredcapabilties' parameter to the function, which accepts an list of abbreviated capabilities for  checking access against question banks before they are returned.
