This file has been replaced by UPGRADING.md. See MDL-81125 for further information.

This files describes API changes in /customfield/*,
Information provided here is intended especially for developers.

=== 4.4 ===
* Enhance the handling of files embedded within textarea custom fields in the course backup and restore functionalities.
  These files are now properly backed up when a course is backed up, and restored when the course is restored.
  Other types of custom fields can also benefit from this new API. See MDL-79151 for more information.
  `\core_customfield\handler::restore_instance_data_from_backup()` now conditionally returns a data_controller id and
  there are two new methods, `\core_customfield\data_controller::backup_define_structure()` and
  `\core_customfield\data_controller::restore_define_structure()`.

=== 4.3 ===
* Field categories are now consistently of type `PARAM_TEXT`, ensure instance `get_formatted_name()` helper is used
  during output

=== 4.2 ===
* The `\customfield_select\field_controller::get_options_array` method, deprecated since 3.10, has been removed, use
  the field instance `get_options` method instead

=== 3.11 ===
* Methods \core_customfield\handler::get_field_config_form() and \core_customfield\handler::setup_edit_page() are no
  longer used. Components that define custom fields areas do not need to implement them. Field edit form opens in
  the modal now.
