This files describes API changes in /mod/perform/element/redisplay/*,
information provided here is intended especially for developers.

=== 18.0 ===

* Redisplay elements can now be configured to redisplay responses from elements in the same activity instance (instead of
  previous instances from the same activity). For this, an input parameter 'same_subject_instance' was added to the GraphQL
  type 'subject_instance_previous_responses_input'.

=== 16.0 ===

* Redisplay elements can now have missing records in the perform_section_element_reference table when the source activity
  is deleted. To account for that, the performelement_redisplay\redisplay::post_update() method will no longer throw
  an exception when the redisplay element does not have a record in perform_section_element_reference. Instead, it will
  create a new one.
