  - MOD_PURPOSE_COLLABORATION
  - MOD_PURPOSE_CONTENT
  - MOD_PURPOSE_ADMINISTRATION
  - MOD_PURPOSE_INTERFACE
  - MOD_PURPOSE_OTHER

* The format_base is now deprecated. Use core_courseformat\base instead.

  - core_courseformat\output\local\content\section\*: to render parts of the course section
* The previous format renderer page_title method has been moved to course_format::page_title
* New format renderer methods to interact with the new output components:
  - render: override the default templatable mustache location for the new course components.

* New external \core_course\external\get_enrolled_courses_with_action_events_by_timeline_classification:
  - Returns courses the user is enrolled in which contain at least one action event in the supplied time/text filtering parameters.

    action events.
* The following functions have been deprecated in favour the tertiary navigation constructs:
  - management_heading
  - course_search_form
  - print_course_request_buttons
* New page_setup() method in the core_course_category class. This method can be used for a general page setup in the course

  structure in the course competency pages has been replaced with tertiary navigation. To render the navigation, please
  render_course_completion_action_bar() instead.

  - get_array_of_activities (replaced by course_modinfo::get_array_of_activities() for better performance)
* New course_modinfo::purge_course_cache function was created to purge the cache of a given course.

=== 3.11 ===
* A new callback xxx_coursemodule_definition_after_data that allows plugins to extend activity forms after the data is set.
* \core_course_renderer::course_section_cm_completion() has been deprecated. It is not being used anymore and is being replaced by
  \core_renderer::activity_information().
* New Behat steps for checking activity date information in the \behat_course class:
  - activity_date_in_activity_should_contain_text()
    - Given the activity date in "<ActivityName>" should contain "<Text>"
  - activity_dates_information_in_activity_should_exist()
