   2  information provided here is intended especially for developers.
   3  
   4  === 3.2 ===
   5  
   6  * Callback delete_course is deprecated and should be replaced with observer for event \core\event\course_content_deleted
   7  
   8  === 3.1 ===
   9  
  10  * Old /mod/MODULENAME/pix/icon.gif and enrol/paypal/pix/icon.gif GIF icons have been removed. Please use pix_icon
  11    renderable instead.
  12  * Callback get_types() is deprecated, instead activity modules can define callback get_shortcuts().
  13    See source code for get_module_metadata().
  14  
  15  === 3.0 ===
  16  
  17  * Dropped support for the $module in mod/xxx/version.php files (deprecated
  18    since 2.7). All activity modules must use the $plugin syntax now. See
  19    https://docs.moodle.org/dev/version.php for details (MDL-43896).
  20  * Modules using rating component must implement a callback mod_x_rating_can_see_item_ratings(). Refer
  21    to mod_forum_rating_can_see_item_ratings() for example.
  22  
  23  === 2.9 ===
  24  
  25  * Added Grade to pass field to mod_form for activities that support grading.
  26  * The method moodleform_mod::add_intro_editor() used in mod_form.php form
  27    definitions has been deprecated. Replace it with the new
  28    moodleform_mod::standard_intro_elements() method that takes the new site
  29    configuration requiremodintro into account (MDL-49101).
  30  
  31  === 2.8 ===
  32  
  33  * Constant FEATURE_GROUPMEMBERSONLY is deprecated. Modules should remove this
  34    constant from their module_supports() API function.
  35  * $CFG->enablegroupmembersonly no longer exists.
  36  
  37  === 2.7 ===
  38  
  39  * modgrade form element has been redesigned and allows setting the maximum grade point higher than 100.
  40  * The usage of $module in mod/xxx/version.php files is now deprecated. Please use
  41    $plugin instead. The support for the legacy notation will be dropped in Moodle 2.10.
  42  * xxx_get_view_actions() and xxx_get_post_actions() will be ignored by new logging system for
  43    participation report. view_action and post_action will be detected by event's crud and edulevel.
  44  * The functions xxx_user_outline() and xxx_user_complete() have been removed from the majority of core modules (see MDL-41286),
  45    except for those that require unique functionality. These functions are used by the outline report, but now if they no longer
  46    exist, the default behaviour is chosen, which supports the legacy and standard log storages introduced in 2.7 (see MDL-41266).
  47    It is highly recommended you remove these functions from your module if they are simply performing the default behaviour.
  48  
  49  === 2.6 ===
  50  
  51  * Modules using the question bank MUST now declare their use of it with the xxx_supports()
  52    flag FEATURE_USES_QUESTIONS.
  53  * xxx_get_types() module callback can now return subtypes that have
  54    a custom help text set. Also instead of array it can now return
  55    MOD_SUBTYPE_NO_CHILDREN. This is optional and still defaults to prior
  56    behavior. See get_module_metadata() in course/lib.php for details.
  57  * shift_course_mod_dates() has been modified to accept optional mod instance id. If mod instance id is passed then
  58    dates changed will happen only on specific module instance and not on all instances of that module in course.
  59  
  60  === 2.5 ===
  61  
  62  * support for 'mod/*' filters was removed

  84    contains additional options for the file serving. The array should be re-passed
  85    to send_stored_file().
