6* There is a new privacy API that every subsystem and plugin has to implement so that the site can become GDPR
7 compliant. Plugins use this API to report what information they store or process regarding users, and provide ability
8 to export and delete personal data. See https://docs.moodle.org/dev/Privacy_API for guidelines on how to implement the
9 privacy API in your plugin.
cd305dc2 10* The cron runner now sets up a fresh PAGE and OUTPUT between each task.
76f8b361
EL
11* The core_renderer methods notify_problem(), notify_success(), notify_message() and notify_redirect() that were
12 deprecated in Moodle 3.1 have been removed. Use \core\notification::add(), or \core\output\notification as required.
521252d6
DM
13* The maximum supported precision (the total number of digits) for XMLDB_TYPE_NUMBER ("number") fields raised from 20 to
14 38 digits. Additionally, the whole number part (precision minus scale) must not be longer than the maximum length of
15 integer fields (20 digits). Note that PHP floats commonly support precision of roughly 15 digits only (MDL-32113).
0e68db9e
EL
16* Event triggering and event handlers:
17 - The following events, deprecated since moodle 2.6, have been finally removed: groups_members_removed,
18 groups_groupings_groups_removed, groups_groups_deleted, groups_groupings_deleted.
56c9d666
JP
19* The following functions have been finally deprecated and can not be used any more:
20 - notify()
54a099e9
EL
21* XMLDB now validates the PATH attribute on every install.xml file. Both the XMLDB editor and installation will fail
22 when a problem is detected with it. Please ensure your plugins contain correct directory relative paths.
caae0820 23* Add recaptchalib_v2.php for support of reCAPTCHA v2.
1727c939
MG
24* Plugins can define class 'PLUGINNAME\privacy\local\sitepolicy\handler' if they implement an alternative mechanisms for
25 site policies managements and agreements. Administrators can define which component is to be used for handling site
26 policies and agreements. See https://docs.moodle.org/dev/Site_policy_handler
0bdc5785
DM
27* Scripts can define a constant NO_SITEPOLICY_CHECK and set it to true before requiring the main config.php file. It
28 will make the require_login() skipping the test for the user's policyagreed status. This is useful for plugins that
29 act as a site policy handler.
c2e97077
DM
30* There is a new is_fulltext_search_supported() DML function. The default implementation returns false. This function
31 is used by 'Simple search' global search engine to determine if the database full-text search capabilities can be used.
3cfbce12
JP
32* The following have been removed from the list of core subsystems:
33 - core_register
34 - core_publish
3127fe10
MG
35 Following this change, \core_register_renderer and \core_publish_renderer have been removed and their methods have been
36 moved to \core_admin_renderer and \core_course_renderer respectively.
521252d6 37
8cf36e9c 38=== 3.4 ===
521252d6 39
d3882ea4 40* oauth2_client::request method has an extra parameter to specify the accept header for the response (MDL-60733)
f83d212b
EL
41* The following functions, previously used (exclusively) by upgrade steps are not available
42 anymore because of the upgrade cleanup performed for this version. See MDL-57432 for more info:
43 - upgrade_mimetypes()
44 - upgrade_fix_missing_root_folders_draft()
45 - upgrade_minmaxgrade()
46 - upgrade_course_tags()
47
8cf36e9c
DM
48* Added new moodleform element 'filetypes' and new admin setting widget 'admin_setting_filetypes'. These new widgets
49 allow users to define a list of file types; either by typing them manually or selecting them from a list. The widgets
50 directly support the syntax used to feed the 'accepted_types' option of the filemanager and filepicker elements. File
51 types can be specified as extensions (.jpg or just jpg), mime types (text/plain) or groups (image).
e705e69e
TL
52* Removed accesslib private functions: load_course_context(), load_role_access_by_context(), dedupe_user_access() (MDL-49398).
53* Internal "accessdata" structure format has changed to improve ability to perform role definition caching (MDL-49398).
54* Role definitions are no longer cached in user session (MDL-49398).
0f398b50
JL
55* External function core_group_external::get_activity_allowed_groups now returns an additional field: canaccessallgroups.
56 It indicates whether the user will be able to access all the activity groups.
bef201c7 57* file_get_draft_area_info does not sum the root folder anymore when calculating the foldercount.
6c8e25fa
DM
58* The moodleform element classes can now optionally provide a public function validateSubmitValue(). This method can be
59 used to perform implicit validation of submitted values - without the need to explicitly add the validation rules to
60 every form. The method should accept a single parameter with the submitted value. It should return a string with the
61 eventual validation error, or an empty value if the validation passes.
3b1eba06 62* New user_picture attribute $includefullname to determine whether to include the user's full name with the user's picture.
fd0a43be
JP
63* Enrol plugins which provide enrolment actions can now declare the following "data-action" attributes in their implementation of
64 enrol_plugin::get_user_enrolment_actions() whenever applicable:
65 * "editenrolment" - For editing a user'e enrolment details. Defined by constant ENROL_ACTION_EDIT.
66 * "unenrol" - For unenrolling a student. Defined by constant ENROL_ACTION_UNENROL.
67 These attributes enable enrol actions to be rendered via modals. If not added, clicking on the enrolment action buttons will still
68 redirect the user to the appropriate enrolment action page. Though optional, it is recommended to add these attributes for a
69 better user experience when performing enrol actions.
4047fccb
JP
70* The enrol_plugin::get_user_enrolment_actions() implementations for core enrol plugins have been removed and moved to
71 the parent method itself. New enrol plugins don't have to implement get_user_enrolment_actions(), but just need to
72 make sure that they override:
73 - enrol_plugin::allow_manage(), and/or
74 - enrol_plugin::allow_unenrol_user() or enrol_plugin::allow_unenrol()
75 Existing enrol plugins that override enrol_plugin::get_user_enrolment_actions() don't have to do anything, but can
76 also opt to remove their own implementation of the method if they basically have the same logic as the parent method.
bb1c6f85
JP
77* New optional parameter $enrolid for the following functions:
78 - get_enrolled_join()
79 - get_enrolled_sql()
80 - get_enrolled_with_capabilities_join()
81 Setting this parameter to a non-zero value will add a condition to the query such that only users that were enrolled
82 with this enrolment method will be returned.
198d7291
JP
83* New optional parameter 'closeSuggestionsOnSelect' for the enhance() function for form-autocomplete. Setting this to true will
84 close the suggestions popup immediately after an option has been selected. If not specified, it defaults to true for single-select
85 elements and false for multiple-select elements.
4d068a67 86* user_can_view_profile() now also checks the moodle/user:viewalldetails capability.
237efd4f
JP
87* The core/modal_confirm dialogue has been deprecated. Please use the core/modal_save_cancel dialogue instead. Please ensure you
88 update to use the ModalEvents.save and ModalEvents.cancel events instead of their yes/no counterparts.
93b47710
MN
89* Instead of checking the 'moodle/course:viewparticipants' and 'moodle/site:viewparticipants' capabilities use the
90 new functions course_can_view_participants() and course_require_view_participants().
b1eb6dd7 91* $stored_file->add_to_curl_request() now adds the filename to the curl request.
b58764ff
JO
92* The option for Login HTTPS (authentication-only SSL) has been removed
93* $CFG->loginhttps is now deprecated, do not use it.
4b501ec9 94* $PAGE->https_required and $PAGE->verify_https_required() are now deprecated. They are no longer used and will throw a coding_exception.
672f4836 95* $CFG->httpswwwroot is now deprecated and will always result in the same value as wwwroot.
a63cd3e2
AH
96* Added function core_role_set_view_allowed() to check if a user should be able to see a given role.
97 This should be checked whenever displaying a list of roles to a user, however, core_role_set_assign_allowed may need to override it
98 in some cases.
64cd4596 99* Deprecated allow_override, allow_assign and allow_switch and replaced with core_role_set_*_allowed to avoid function names conflicting.
8cf36e9c 100
67bebb69
IA
101=== 3.3.1 ===
102
103* ldap_get_entries_moodle() now always returns lower-cased attribute names in the returned entries.
104 It was suppposed to do so before, but it actually didn't.
105
3be09119 106=== 3.3 ===
1cb5c7b3 107
69cdead3
DP
108* Behat compatibility changes are now being documented at
109 https://docs.moodle.org/dev/Acceptance_testing/Compatibility_changes
55946a89
EL
110* PHPUnit's bootstrap has been changed to use HTTPS wwwroot (https://www.example.com/moodle) from previous HTTP version. Any
111 existing test expecting the old HTTP URLs will need to be switched to the new HTTPS value (reference: MDL-54901).
f59d81f4
DW
112* The information returned by the idp list has changed. This is usually only rendered by the login page and login block.
113 The icon attribute is removed and an iconurl attribute has been added.
151b0f94 114* Support added for a new type of external file: FILE_CONTROLLED_LINK. This is an external file that Moodle can control
141ee541 115 the permissions. Moodle makes files read-only but can grant temporary write access.
151b0f94
DW
116 When accessing a URL, the info from file_browser::get_file_info will be checked to determine if the user has write access,
117 if they do - the remote file will have access controls set to allow editing.
547801a4
FM
118* The method moodleform::after_definition() has been added and can now be used to add some logic
119 to be performed after the form's definition was set. This is useful for intermediate subclasses.
c8d0efc3
DW
120* Moodle has support for font-awesome icons. Plugins should use the xxx_get_fontawesome_icon_map callback
121 to map their custom icons to one from font-awesome.
122* $OUTPUT->pix_url() has been deprecated because it is was used mostly to manually generate image tags for icons.
123 We now distinguish between icons and "small images". The difference is that an icon does not have to be rendered as an image tag
124 with a source. It is OK to still have "small images" - if this desired use $OUTPUT->image_icon() and $OUTPUT->image_url(). For
125 other uses - use $OUTPUT->pix_icon() or the pix helper in mustache templates {{#pix}}...{{/pix}}
c266d256 126 For other valid use cases use $OUTPUT->image_url().
3e6adcd6 127* Activity icons have been split from standard icons. Use $OUTPUT->image_icon instead of $OUTPUT->pix_icon for these
c2dde7ee 128 type of icons (the coloured main icon for each activity).
d83d87f6
DP
129* YUI module moodle-core-formautosubmit has been removed, use jquery .change() instead (see lib/templates/url_select.mustache for
130 an example)
2fa2ed50
DP
131* $mform->init_javascript_enhancement() is deprecated and no longer does anything. Existing uses of smartselect enhancement
132 should be switched to the searchableselector form element or other solutions.
7620746f 133* Return value of the validate_email() is now proper boolean as documented. Previously the function could return 1, 0 or false.
e7ecb4a9
DP
134* The mcore YUI rollup which included various YUI modules such as moodle-core-notification is no longer included on every
135 page. Missing YUI depdencies may be exposed by this change (e.g. missing a requirement on moodle-core-notification when
136 using M.core.dialogue).
e1a38878
DP
137* Various legacy javascript functions have been removed:
138 * M.util.focus_login_form and M.util.focus_login_error no longer do anything. Please use jquery instead. See
139 lib/templates/login.mustache for an example.
140 * Some outdated global JS functions have been removed and should be replaced with calls to jquery
141 or alternative approaches:
142 checkall, checknone, select_all_in_element_with_id, select_all_in, deselect_all_in, confirm_if, findParentNode,
143 filterByParent, stripHTML

b5830334
EL
282* Relative paths in $CFG->alternateloginurl will be resolved to absolute path within moodle site. Previously they
283 were resolved to absolute path within the server. That means:
234e1449
RT
284 - $CFG->wwwroot: http://example.com/moodle
285 - $CFG->alternateloginurl : /my/super/login.php
286 - Login url will be: http://example.com/moodle/my/super/login.php (moodle root based)
9d5c12be
EL
287* Database (DML) layer:
288 - new sql_equal() method available for places where case sensitive/insensitive varchar comparisons are required.
f834a8f5
RS
289* PostgreSQL connections now use advanced options to reduce connection overhead. These options are not compatible
290 with some connection poolers. The dbhandlesoptions parameter has been added to allow the database to configure the
291 required defaults. The parameters that are required in the database are;
292 ALTER DATABASE moodle SET client_encoding = UTF8;
293 ALTER DATABASE moodle SET standard_conforming_strings = on;
ce7863ba 294 ALTER DATABASE moodle SET search_path = 'moodle,public'; -- Optional, if you wish to use a custom schema.
f834a8f5 295 You can set these options against the database or the moodle user who connects.
fc7f69e7
FM
296* Some form elements have been refined to better support right-to-left languages. In RTL,
297 most fields should not have their direction flipped, a URL, a path to a file, a number, ...
298 are always displayed LTR. Input fields and text areas now will best guess whether they
299 should be forced to be displayed in LTR based on the PARAM type associated with it. You

301 set the value.
370e7637 302* Action menus do_not_enhance() is deprecated, use a list of action_icon instead.

303* The user_not_fully_set_up() function has a new $strict parameter (defaulting to true) in order to decide when
304 custom fields (and other checks) should be evaluated to determine if the user has been completely setup.
3ee392c8

305* profile_field_base class has new methods: get_field_config_for_external() and get_field_properties().
306 This two new methods should be implemented by profile field plugins to make them compatible with Web Services.

307* The minifier library used by core_minify has been switched to https://github.com/matthiasmullie/minify - there are minor differences
308 in minifier output.
8b99e163 309* context_header additional buttons can now have a class attribute provided in the link attributes.

310* The return signature for the antivirus::scan_file() function has changed.
311 The calling function will now handle removal of infected files from Moodle based on the new integer return value.

312* The first parameter $eventdata of both message_send() and \core\message\manager::send_message() should
313 be \core\message\message. Use of stdClass is deprecated.
314* The message_sent event now expects other[courseid] to be always set, exception otherwise. For BC with contrib code,
315 message_sent::create_from_ids() will show a debugging notice if the \core\message\message being sent is missing
316 the courseid property, defaulting to SITEID automatically. In Moodle 3.6 (MDL-55449) courseid will be fully mandatory
317 for all messages sent.
d6a25bc4 318* The send_confirmation_email() function has a new optional parameter $confirmationurl to provide a different confirmation URL.
bb316e07
JD
319* Introduced a new hook for plugin developers:
320 - <component>_course_module_background_deletion_recommended()
321 This hook should be used in conjunction with the existing '<component>_pre_course_module_delete($mod)'. It must
322 return a boolean and is called by core to check whether a plugin's implementation of
323 <component>_pre_course_module_deleted($mod) will take a long time. A plugin should therefore only implement this
324 function if it also implements <component>_pre_course_module_delete($mod).
325 An example in current use is recyclebin, which performs what can be a lengthy backup process in
326 tool_recyclebin_pre_course_module_delete. The recyclebin, if enabled, now returns true in its implementation of
327 tool_recyclebin_course_module_background_deletion_recommended(), to indicate to core that the deletion (and
328 execution of tool_recyclebin_pre_course_module_delete) should be handled with an adhoc task, meaning it will not
329 occur in real time.

358* The core_user::fill_properties_cache() static method has been introduced to be a reference
359 and allow standard user fields data validation. Right now only type validation is supported
360 checking it against the parameter (PARAM_*) type of the target user field. MDL-52781 is

373 function, and \core\output\notification renderable have been deprecated
374 and will be removed in a future version.
375 Notifications should use the levels found in \core\output\notification.
376* The constants for NOTIFY_PROBLEM, NOTIFY_REDIRECT, and NOTIFY_MESSAGE in

392 moodleform in a webservice or ajax script (for example using the new fragments API) we
393 cannot allow the moodleform to parse it's own data from _GET and _POST - we must pass it as
394 an array.

407 * Class moodleform, moodleform_mod and some module classes have been changed to use
408 __construct() for the constructor. Calling parent constructors by the class
409 name will display debugging message. Incorrect: parent::moodleform(),
410 correct: parent::__construct()
411 * All form elements have also changed the constructor syntax. No changes are
412 needed for using form elements, however if plugin defines new form element it
413 needs to use correct syntax. For example, incorrect: parent::HTML_QuickForm_input(),
414 HTML_QuickForm_input::HTML_QuickForm_input(), $this->HTML_QuickForm_input().
415 Correct: HTML_QuickForm_input::__construct() or parent::__construct().

426* The previous events API handlers are being deprecated in favour of events 2 API, debugging messages are being displayed if
427 there are 3rd party plugins using it. Switch to events 2 API please, see https://docs.moodle.org/dev/Event_2#Event_dispatching_and_observers
428 Note than you will need to bump the plugin version so moodle is aware that you removed the plugin's event handlers.

435 is now a part of \antivirus_clamav\scanner class methods.
436* \repository::antivir_scan_file() has been deprecated, \core\antivirus\manager::scan_file() that
375223c6 437 applies antivirus plugins is replacing its functionality.
d84a657d 438* Added core_text::str_max_bytes() which safely truncates multi-byte strings to a maximum number of bytes.
b5e6ec44 439* Zend Framework has been removed completely.
322f3141 440* Any plugin can report when a scale is being used with the callback function [pluginname]_scale_used_anywhere(int $scaleid).
529ea77b 441* Changes in file_rewrite_pluginfile_urls: Passing a new option reverse = true in the $options var will make the function to convert
296ab1e2 442 actual URLs in $text to encoded URLs in the @@PLUGINFILE@@ form.

454 - <component>_pre_course_module_delete($cm)
455 - <component>_pre_block_delete($instance)
456 - <component>_pre_user_delete($user)
457 These hooks allow developers to use the item in question before it is deleted by core. For example, if your plugin is
458 a module (plugins located in the mod folder) called 'xxx' and you wish to interact with the user object before it is
459 deleted then the function to create would be mod_xxx_pre_user_delete($user) in mod/xxx/lib.php.

664* Gradebook grade category option "aggregatesubcats" has been removed completely.
665 This means that the database column is removed, the admin settings are removed and
666 the properties from the grade_category object have been removed. If any courses were
667 found to be using this setting, a warning to check the grades will be shown in the
668 course grader report after upgrading the site. The same warning will be shown on
669 courses restored from backup that had this setting enabled (see MDL-47503).
4051685b 670* lib/excelllib.class.php has been updated. The class MoodleExcelWorkbook will now only produce excel 2007 files.

671* renderers: We now remove the suffix _renderable when looking for a render method for a renderable.
672 If you have a renderable class named like "blah_renderable" and have a method on a renderer named "render_blah_renderable"
673 you will need to change the name of your render method to "render_blah" instead, as renderable at the end is no longer accepted.
d25c41fb 674* New functions get_course_and_cm_from_cmid($cmorid, $modulename) and
675 get_course_and_cm_from_instance($instanceorid, $modulename) can be used to
676 more efficiently load these basic data objects at the start of a script.
677* New function cm_info::create($cm) can be used when you need a cm_info
678 object, but have a $cm which might only be a standard database record.
061e6b28 679* $CFG->enablegroupmembersonly no longer exists.

8d1f33e1 772* Conditional availability API has moved and changed. The condition_info class is
773 replaced by \core_availability\info_module, and condition_info_section by
774 \core_availability\info_section. (Code that uses the old classes will generally
775 still work.)
776* coursemodule_visible_for_user() has been deprecated but still works - replaced
777 by a new static function \core_availability\info_module::is_user_visible()
778* cm_info::is_user_access_restricted_by_conditional_access has been deprecated
779 but still works (it has never done what its name suggests, and is
780 unnecessary).
781* cm_info and section_info property showavailability has been deprecated, but
782 still works (with the caveat that this information is now per-user).
783* cm_info and section_info properties availablefrom and availableuntil have been

793* New conditional availability API in /availability, including new availability
794 condition plugins in /availability/condition. The new API is very similar with
795 regard to checking availability, but any code that modifies availability settings
796 for an activity or section is likely to need substantial changes.

FM
823 get_plugin_list(), get_plugin_list_with_class(), get_plugin_directory(), normalize_component(),
824 get_component_directory() and get_plugin_list_with_file(). The names of the new methods are
825 exactly the same, the only differences are that core_component::get_plugin_types() now always returns
826 full paths and core_component::get_plugin_list() does not accept empty parameter any more.
d534708f 827* Use core_text::* instead of textlib:: and also core_collator::* instead of collatorlib::*.
af578aec 828* Use new function moodleform::mock_submit() to simulate form submission in unit tests (backported).

PS
830* MS SQL Server drivers are now using NVARCHAR(MAX) instead of NTEXT and VARBINARY(MAX) instead of IMAGE,
831 this change should be fully transparent and it should help significantly with add-on compatibility.
598a82c9
PS
832* The string manager classes were renamed. Note that they should not be modified or used directly,
833 always use get_string_manager() to get instance of the string manager.

PS
835* Use $CFG->debugdeveloper instead of debugging('', DEBUG_DEVELOPER).

ac2b2713 840* Subplugins are supported in admin tools and local plugins.
71ab7e51 841* file_packer/zip_packer API has been modified so that key functions support a new file_progress interface
842 to report progress during long operations. Related to this, zip_archive now supports an estimated_count()
843 function that returns an approximate number of entries in the zip faster than the count() function.
d872881f 844* Class cm_info no longer extends stdClass. All properties are read-only and calculated on first request only.
44ddd2a1 845* Class course_modinfo no longer extends stdClass. All properties are read-only.
64501eee
MG
846* Database fields modinfo and sectioncache in table course are removed. Application cache core/coursemodinfo
847 is used instead. Course cache is still reset, rebuilt and retrieved using function rebuild_course_cache() and
848 get_fast_modinfo(). Purging all caches and every core upgrade purges course modinfo cache as well.
849 If function get_fast_modinfo() is called for multiple courses make sure to include field cacherev in course
850 object.

851* Internal (noreply and support) user support has been added for sending/receiving message.
852 Use core_user::get_noreply_user() and core_user::get_support_user() to get noreply and support user's respectively.
853 Real users can be used as noreply/support users by setting $CFG->noreplyuserid and $CFG->supportuserid
137885b7 854* New function readfile_allow_large() in filelib.php for use when very large files may need sending to user.
e87214bd 855* Use core_plugin_manager::reset_caches() when changing visibility of plugins.

723a6e56 858* Module and block tables do not contain version column any more, use get_config('xx_yy', 'version') instead.
5fed8433 859* $USER->password field is intentionally unset so that session data does not contain password hashes.
38fc0130 860* Use core_shutdown_manager::register_function() instead of register_shutdown_function().
c858655d 861* New file packer for .tar.gz files; obtain by calling get_file_packer('application/x-gzip'). Intended initially
862 for use in backup/restore only, as there are limitations on supported filenames. Also new packer for
863 backups which supports both compression formats; get_file_packer('application/vnd.moodle.backup').
864* New optional parameter to stored_file::get_content_file_handle to open file handle with 'gzopen' instead
865 of 'fopen' to read gzip-compressed files if required.
6c679d15 866* update_internal_user_password() and setnew_password_and_mail() now trigger user_updated event.
b2858b91 867* Add thirdpartylibs.xml file to plugins that bundle any 3rd party libraries.
2dd8e935

868* New class introduced to help auto generate zIndex values for modal dialogues. Class "moodle-has-zindex"
869 should set on any element which uses a non-default zindex and needs to ensure it doesn't show above a
870 dialogue.
0c431257
PS
871* $CFG->filelifetime is now used consistently for most file serving operations, the default was lowered
872 to 6 hours from 24 hours because etags and x-sendfile support should make file serving less expensive.

873* Date format locale charset for windows server will come from calendar type and for gregorian it will use
874 lang file.

875* The library to interact with Box.net (class boxclient) is only compatible with their APIv1 which
876 reaches its end of life on the 14th of Dec. You should migrate your scripts to make usage of the
877 new class boxnet_client(). Note that the method names and return values have changed.

1022* The database drivers (moodle_database and subclasses) aren't using anymore the ::columns property
1023 for caching database metadata. MUC (databasemeta) is used instead. Any custom DB driver should
1024 apply for that change.

1025* The cron output has been changed to include time and memory usage (see cron_trace_time_and_memory()),
1026 so any custom utility relying on the old output may require modification.

1027* Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
1028 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
1029 an option for 0 bytes. Existing code that was replacing the 0 option in the return
1030 from this function with a more sensible message, can now use the return from this function directly.

1038* The function delete_course_module was deprecated and has been replaced with
1039 course_delete_module. The reason for this was because the function delete_course_module
1040 only partially deletes data, so wherever it was called extra code was needed to
1041 perform the whole deletion process. The function course_delete_module now takes care
1042 of the whole process.

1043* curl::setopt() does not accept constant values any more. As it never worked properly,

1046* Function get_users_listing now return list of users except guest and deleted users. Previously
1047 deleted users were excluded by get_users_listing. As guest user is not expected while browsing users,
1048 and not included in get_user function, it will not be returned by get_users_listing.

1049* The add_* functions in course/dnduploadlib.php have been deprecated. Plugins should be using the
1050 MODNAME_dndupload_register callback instead.

1051* The signature of the add() method of classes implementing the parentable_part_of_admin_tree
1052 interface (such as admin_category) has been extended. The new parameter allows the caller
1053 to prepend the new node before an existing sibling in the admin tree.

1061 in lib/coursecatlib.php, functions responsible for rendering courses and categories lists are
1062 moved to course/renderer.php. The following global functions are deprecated: make_categories_list(),

1071* Additional (optional) param $onlyactive has been added to get_enrolled_users, count_enrolled_users
1072 functions to get information for only active (excluding suspended enrolments) users. Included two
1073 helper functions extract_suspended_users, get_suspended_userids to extract suspended user information.
e87214bd 1074* The core_plugin_manager class now provides two new helper methods for getting information
d7d48b40 1075 about known plugins: get_plugins_of_type() and get_subplugins_of_plugin().
e87214bd 1076* The get_uninstall_url() method of all subclasses of \core\plugininfo\base class is now expected
73658371
DM
1077 to always return moodle_url. Subclasses can use the new method is_uninstall_allowed()
1078 to control the availability of the 'Uninstall' link at the Plugins overview page (previously
1079 they would do it by get_uninstall_url() returning null). By default, URL to a new general plugin
1080 uninstall tool is returned. Unless the plugin type needs extra steps that can't be handled by
1081 plugininfo_xxx::uninstall() method or xmldb_xxx_uninstall() function, this default URL should
1082 satisfy all plugin types.
