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

=== 4.4 ===
* The following behat steps are now deprecated and replaced by new ones with no Javascript dependencies:
  - I add a ":activityname" to section ":sectionnum"
  - I add a ":activityname" to section ":sectionnum and I fill the form with:"
  The new steps are:
  - I add a :activityname to section :sectionnum using the activity chooser
  - I add a :activitypluginname activity to course :coursefullname section :sectionnum
  - I add a :activitypluginname activity to course :coursefullname section :sectionnum and I fill the form with:
* set_coursemodule_visible() has a new $rebuildcache parameter. If this is being called multiple times in the same request,
  consider passing `false` for this parameter and rebuilding the cache once after all the course modules have been updated.
  See course_update_section() for an example.
* The external function core_course::get_courses_by_field now returns the communication tool configuration for the course.
  - communicationroomname: the room name
  - communicationroomurl: the tool url
* The following previously deprecated methods have been removed and can no longer be used:
  - `course_purge_section_cache`
  - `course_purge_module_cache`
  - `get_array_of_activities`
  - `core_course_management_renderer::management_heading`
  - `core_course_management_renderer::course_search_form`
* New format actions classes. Those classes will eventually replace all course/lib.php content editing functions.
  All new methods are distributed in three classes formats can extend. Method can be accessed using static
  methods (see doc block of core_courseformat\formatactions for more information).
* The monologo activity icons have been improved and .png files have been removed (although the API still supports them).
The background for these icons has been removed and the color is used now for outlining their shapes.
About the categories supported by the FEATURE_MOD_PURPOSE:
  * A new category has been added: MOD_PURPOSE_INTERACTIVECONTENT.
  * The MOD_PURPOSE_INTERFACE category has been deprecated. The styles associated with this category have been removed.
The colors for all these purposes and the filters applied to outline them are defined in theme/boost/scss/moodle/variables.scss
* New hooks for extending course form:
 - core_course\hook\after_form_definition
 - core_course\hook\after_form_definition_after_data
 - core_course\hook\after_form_validation
 - core_course\hook\after_form_submission
* New behat step using the URL resolvers:
 - When I am on the "Course > <section> "course > section" page logged in as "<username>". When utilizing 'Section x'
 it first searches by section name (Section x). If it's not found, then it searches by the section number (x).
* The template core_course/course_search_form has been removed following its cessation of use upon MDL-69454 in version 3.11.
* New parameter 'requiredfields' added to \core_course_external::get_enrolled_courses_by_timeline_classification() to allow
  callers of this function to specify only the required course fields.
* Set default values for the following course_summary_exporter properties:
  - summary (null)
  - summaryformat (FORMAT_MOODLE)
  - pdfexportfont (null)

=== 4.3 ===
* The `core_course_renderer::course_section_cm_completion` method has been removed, and can no longer be used
* External function core_course_external::get_course_contents() now returns a new field activitybadge with the data to display
  the activity badge when the module implements it.
* prepare_new_moduleinfo_data() now accepts a parameter "suffix" that will be added to the name of the completion rules.
* The method core_course_bulk_activity_completion_renderer:: edit_default_completion() has been deprecated and will be removed.
* The `core_course\output\activity_information` output class has been deprecated. Use `core_course\output\activity_completion`
  and `core_course\output\activity_dates` instead.
  Alongside with that, the following methods have been deprecated too:
  - `core_course_renderer::render_activity_information()`
  - `renderer_base::activity_information()`

=== 4.2 ===
* course/mod.php now accepts parameter beforemod for adding course modules. It contains the course module id
  of an existing course module. The new module is inserted before this module.
* The function duplicate_module() now has two new optional parameters:
  - $sectionid to specify section the duplicated course module is placed in
  - $changename to disable changing the name of the course module using the 'duplicatedmodule' lang string
* The method `make_categories_options`, deprecated since 3.10, has been removed
* External function core_course_external::get_courses_by_field and core_course_external::search_courses now return a field
called "courseimage" containing a URL pointing to the course image.
* External function core_course_external::get_course_contents() does not throw exceptions for invalid course formats anymore.

=== 4.1 ===
* The function course_modchooser() has been finally deprecated and can not be used anymore. Please use
  course_activitychooser() instead.
* A critical accessibility issue is been found (MDL-74800) at the output class
  core_courseformat\output\local\content\cm\cmname. To solve the problem this output element is not
  rendered anymore using inplace_editable but using a regular named_templatable interface.
  Some format plugins that override the deprecated renderer method course_section_cm_name can be affected.
  Check the current course_section_cm_name code to see how to render it properly.

=== 4.0 ===
* All activity icons have been replaced with black monochrome icons. The background
colour for these icons is defined using a new 'FEATURE_MOD_PURPOSE' support variable in the module lib.php file
Available purpose types are:
  - MOD_PURPOSE_COMMUNICATION
  - MOD_PURPOSE_ASSESSMENT
  - MOD_PURPOSE_COLLABORATION
  - MOD_PURPOSE_CONTENT
  - MOD_PURPOSE_ADMINISTRATION
  - MOD_PURPOSE_INTERFACE
  - MOD_PURPOSE_OTHER
The colours for these types are defined in theme/boost/scss/moodle/variables.scss
* The format_base is now deprecated. Use core_courseformat\base instead.

renderer and course format renderer:
  - core_courseformat\output\local\content: to render the general course structure
  - core_courseformat\output\local\content\section: to render a section
  - core_courseformat\output\local\content\cm: to render an activity card inside a section
  - core_courseformat\output\local\content\cm\*: to render parts of the course structure
  - 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.
  - course_section_updated_cm_item: used when the course editor needs to update a cm item HTML.
  - render_content: contrib formats should override this method to change the default template.

* Class core_course\output\course_module_name is deprecated. Now core_courseformat\output\local\content\cm\cmname controls inline edit.
* Calendar menu entry is now moved to User menu items, so the following methods will not return the calendar item anymore:
  - course_get_user_navigation_options
  - core_course_externalcore_course_external::get_user_navigation_options
* New external \core_course\external\get_enrolled_courses_with_action_events_by_timeline_classification:

    action events.
* The following functions have been deprecated in favour the tertiary navigation constructs:
  - management_heading
  - course_search_form
  - print_course_request_buttons

=== 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().
