   1  This files describes API changes in /mod/* - activity modules,
   2  information provided here is intended especially for developers.
   3  
   4  === 2.8 ===
   5  
   6  * Constant FEATURE_GROUPMEMBERSONLY is deprecated. Modules should remove this
   7    constant from their module_supports() API function.
   8  * $CFG->enablegroupmembersonly no longer exists.
   9  
  10  === 2.7 ===
  11  
  12  * modgrade form element has been redesigned and allows setting the maximum grade point higher than 100.
  13  * The usage of $module in mod/xxx/version.php files is now deprecated. Please use
  14    $plugin instead. The support for the legacy notation will be dropped in Moodle 2.10.
  15  * xxx_get_view_actions() and xxx_get_post_actions() will be ignored by new logging system for
  16    participation report. view_action and post_action will be detected by event's crud and edulevel.
  17  * The functions xxx_user_outline() and xxx_user_complete() have been removed from the majority of core modules (see MDL-41286),
  18    except for those that require unique functionality. These functions are used by the outline report, but now if they no longer
  19    exist, the default behaviour is chosen, which supports the legacy and standard log storages introduced in 2.7 (see MDL-41266).
  20    It is highly recommended you remove these functions from your module if they are simply performing the default behaviour.
  21  
  22  === 2.6 ===
  23  
  24  * Modules using the question bank MUST now declare their use of it with the xxx_supports()
  25    flag FEATURE_USES_QUESTIONS.
  26  * xxx_get_types() module callback can now return subtypes that have
  27    a custom help text set. Also instead of array it can now return
  28    MOD_SUBTYPE_NO_CHILDREN. This is optional and still defaults to prior
  29    behavior. See get_module_metadata() in course/lib.php for details.
  30  * shift_course_mod_dates() has been modified to accept optional mod instance id. If mod instance id is passed then
  31    dates changed will happen only on specific module instance and not on all instances of that module in course.
  32  
  33  === 2.5 ===
  34  
  35  * support for 'mod/*' filters was removed
  36  
  37  === 2.4 ===

  39  new features:
  40  
  41  * mod/xxx/adminlib.php may now include 'plugininfo_yoursubplugintype' class definition
  42    used by plugin_manager; it is recommended to store extra admin settings classes in this file

  55    (unless your mod is a MOD_ARCHETYPE_SYSTEM).
  56  * xxx_pluginfile() is now given the 7th parameter (hopefully the last one) that
  57    contains additional options for the file serving. The array should be re-passed
  58    to send_stored_file().
  59  
  60  * most resourcelib_embed_* functions are replaced with core_media_renderer;
  61    for an example, see mod/resource/locallib.php, resource_display_embed()
