6* Custom AJAX handlers for the form autocomplete fields can now optionally return string in their processResults()
7 callback. If a string is returned, it is displayed instead of the list if suggested items. This can be used, for
8 example, to inform the user that there are too many items matching the current search criteria.

DM
34* There is a new privacy API that every subsystem and plugin has to implement so that the site can become GDPR
35 compliant. Plugins use this API to report what information they store or process regarding users, and provide ability
36 to export and delete personal data. See https://docs.moodle.org/dev/Privacy_API for guidelines on how to implement the
37 privacy API in your plugin.
cd305dc2 38* The cron runner now sets up a fresh PAGE and OUTPUT between each task.
76f8b361
EL
39* The core_renderer methods notify_problem(), notify_success(), notify_message() and notify_redirect() that were

521252d6
DM
41* The maximum supported precision (the total number of digits) for XMLDB_TYPE_NUMBER ("number") fields raised from 20 to
42 38 digits. Additionally, the whole number part (precision minus scale) must not be longer than the maximum length of
43 integer fields (20 digits). Note that PHP floats commonly support precision of roughly 15 digits only (MDL-32113).

44* Event triggering and event handlers:
45 - The following events, deprecated since moodle 2.6, have been finally removed: groups_members_removed,

1727c939
MG
52* Plugins can define class 'PLUGINNAME\privacy\local\sitepolicy\handler' if they implement an alternative mechanisms for
53 site policies managements and agreements. Administrators can define which component is to be used for handling site
54 policies and agreements. See https://docs.moodle.org/dev/Site_policy_handler
0bdc5785
DM
55* Scripts can define a constant NO_SITEPOLICY_CHECK and set it to true before requiring the main config.php file. It
56 will make the require_login() skipping the test for the user's policyagreed status. This is useful for plugins that
57 act as a site policy handler.
c2e97077
DM
58* There is a new is_fulltext_search_supported() DML function. The default implementation returns false. This function
59 is used by 'Simple search' global search engine to determine if the database full-text search capabilities can be used.

73 - upgrade_minmaxgrade()
74 - upgrade_course_tags()
75
8cf36e9c
DM
76* Added new moodleform element 'filetypes' and new admin setting widget 'admin_setting_filetypes'. These new widgets
77 allow users to define a list of file types; either by typing them manually or selecting them from a list. The widgets
78 directly support the syntax used to feed the 'accepted_types' option of the filemanager and filepicker elements. File
79 types can be specified as extensions (.jpg or just jpg), mime types (text/plain) or groups (image).
e705e69e
TL
80* Removed accesslib private functions: load_course_context(), load_role_access_by_context(), dedupe_user_access() (MDL-49398).
81* Internal "accessdata" structure format has changed to improve ability to perform role definition caching (MDL-49398).
82* Role definitions are no longer cached in user session (MDL-49398).
0f398b50
JL
83* External function core_group_external::get_activity_allowed_groups now returns an additional field: canaccessallgroups.
84 It indicates whether the user will be able to access all the activity groups.
bef201c7 85* file_get_draft_area_info does not sum the root folder anymore when calculating the foldercount.
6c8e25fa
DM
86* The moodleform element classes can now optionally provide a public function validateSubmitValue(). This method can be
87 used to perform implicit validation of submitted values - without the need to explicitly add the validation rules to
88 every form. The method should accept a single parameter with the submitted value. It should return a string with the
89 eventual validation error, or an empty value if the validation passes.
3b1eba06 90* New user_picture attribute $includefullname to determine whether to include the user's full name with the user's picture.
fd0a43be
JP
91* Enrol plugins which provide enrolment actions can now declare the following "data-action" attributes in their implementation of
92 enrol_plugin::get_user_enrolment_actions() whenever applicable:
93 * "editenrolment" - For editing a user'e enrolment details. Defined by constant ENROL_ACTION_EDIT.
94 * "unenrol" - For unenrolling a student. Defined by constant ENROL_ACTION_UNENROL.
95 These attributes enable enrol actions to be rendered via modals. If not added, clicking on the enrolment action buttons will still
96 redirect the user to the appropriate enrolment action page. Though optional, it is recommended to add these attributes for a
97 better user experience when performing enrol actions.
4047fccb
JP
98* The enrol_plugin::get_user_enrolment_actions() implementations for core enrol plugins have been removed and moved to
99 the parent method itself. New enrol plugins don't have to implement get_user_enrolment_actions(), but just need to
100 make sure that they override:
101 - enrol_plugin::allow_manage(), and/or
102 - enrol_plugin::allow_unenrol_user() or enrol_plugin::allow_unenrol()
103 Existing enrol plugins that override enrol_plugin::get_user_enrolment_actions() don't have to do anything, but can
104 also opt to remove their own implementation of the method if they basically have the same logic as the parent method.
bb1c6f85
JP
105* New optional parameter $enrolid for the following functions:
106 - get_enrolled_join()
107 - get_enrolled_sql()
108 - get_enrolled_with_capabilities_join()
109 Setting this parameter to a non-zero value will add a condition to the query such that only users that were enrolled
110 with this enrolment method will be returned.
198d7291
JP
111* New optional parameter 'closeSuggestionsOnSelect' for the enhance() function for form-autocomplete. Setting this to true will
112 close the suggestions popup immediately after an option has been selected. If not specified, it defaults to true for single-select
113 elements and false for multiple-select elements.
4d068a67 114* user_can_view_profile() now also checks the moodle/user:viewalldetails capability.
237efd4f
JP
115* The core/modal_confirm dialogue has been deprecated. Please use the core/modal_save_cancel dialogue instead. Please ensure you
116 update to use the ModalEvents.save and ModalEvents.cancel events instead of their yes/no counterparts.
93b47710
MN
117* Instead of checking the 'moodle/course:viewparticipants' and 'moodle/site:viewparticipants' capabilities use the
118 new functions course_can_view_participants() and course_require_view_participants().
b1eb6dd7 119* $stored_file->add_to_curl_request() now adds the filename to the curl request.
b58764ff
JO
120* The option for Login HTTPS (authentication-only SSL) has been removed
121* $CFG->loginhttps is now deprecated, do not use it.
4b501ec9 122* $PAGE->https_required and $PAGE->verify_https_required() are now deprecated. They are no longer used and will throw a coding_exception.
672f4836 123* $CFG->httpswwwroot is now deprecated and will always result in the same value as wwwroot.
a63cd3e2
AH
124* Added function core_role_set_view_allowed() to check if a user should be able to see a given role.
125 This should be checked whenever displaying a list of roles to a user, however, core_role_set_assign_allowed may need to override it
126 in some cases.
64cd4596 127* Deprecated allow_override, allow_assign and allow_switch and replaced with core_role_set_*_allowed to avoid function names conflicting.
8cf36e9c 128
67bebb69
IA
129=== 3.3.1 ===
130
131* ldap_get_entries_moodle() now always returns lower-cased attribute names in the returned entries.
132 It was suppposed to do so before, but it actually didn't.
133

DP
136* Behat compatibility changes are now being documented at
137 https://docs.moodle.org/dev/Acceptance_testing/Compatibility_changes
55946a89
EL
138* PHPUnit's bootstrap has been changed to use HTTPS wwwroot (https://www.example.com/moodle) from previous HTTP version. Any
139 existing test expecting the old HTTP URLs will need to be switched to the new HTTPS value (reference: MDL-54901).
f59d81f4
DW
140* The information returned by the idp list has changed. This is usually only rendered by the login page and login block.
141 The icon attribute is removed and an iconurl attribute has been added.
151b0f94 142* Support added for a new type of external file: FILE_CONTROLLED_LINK. This is an external file that Moodle can control
141ee541 143 the permissions. Moodle makes files read-only but can grant temporary write access.
151b0f94
DW
144 When accessing a URL, the info from file_browser::get_file_info will be checked to determine if the user has write access,
145 if they do - the remote file will have access controls set to allow editing.
547801a4
FM
146* The method moodleform::after_definition() has been added and can now be used to add some logic
147 to be performed after the form's definition was set. This is useful for intermediate subclasses.
c8d0efc3
DW
148* Moodle has support for font-awesome icons. Plugins should use the xxx_get_fontawesome_icon_map callback
149 to map their custom icons to one from font-awesome.
150* $OUTPUT->pix_url() has been deprecated because it is was used mostly to manually generate image tags for icons.
151 We now distinguish between icons and "small images". The difference is that an icon does not have to be rendered as an image tag
152 with a source. It is OK to still have "small images" - if this desired use $OUTPUT->image_icon() and $OUTPUT->image_url(). For
153 other uses - use $OUTPUT->pix_icon() or the pix helper in mustache templates {{#pix}}...{{/pix}}
c266d256 154 For other valid use cases use $OUTPUT->image_url().
3e6adcd6 155* Activity icons have been split from standard icons. Use $OUTPUT->image_icon instead of $OUTPUT->pix_icon for these
c2dde7ee 156 type of icons (the coloured main icon for each activity).
d83d87f6
DP
157* YUI module moodle-core-formautosubmit has been removed, use jquery .change() instead (see lib/templates/url_select.mustache for
158 an example)
2fa2ed50
DP
159* $mform->init_javascript_enhancement() is deprecated and no longer does anything. Existing uses of smartselect enhancement
160 should be switched to the searchableselector form element or other solutions.
7620746f 161* Return value of the validate_email() is now proper boolean as documented. Previously the function could return 1, 0 or false.
e7ecb4a9
DP
162* The mcore YUI rollup which included various YUI modules such as moodle-core-notification is no longer included on every
163 page. Missing YUI depdencies may be exposed by this change (e.g. missing a requirement on moodle-core-notification when
164 using M.core.dialogue).
e1a38878
DP
165* Various legacy javascript functions have been removed:
166 * M.util.focus_login_form and M.util.focus_login_error no longer do anything. Please use jquery instead. See
167 lib/templates/login.mustache for an example.
168 * Some outdated global JS functions have been removed and should be replaced with calls to jquery
169 or alternative approaches:

317* PostgreSQL connections now use advanced options to reduce connection overhead. These options are not compatible
318 with some connection poolers. The dbhandlesoptions parameter has been added to allow the database to configure the
319 required defaults. The parameters that are required in the database are;
320 ALTER DATABASE moodle SET client_encoding = UTF8;
321 ALTER DATABASE moodle SET standard_conforming_strings = on;
ce7863ba 322 ALTER DATABASE moodle SET search_path = 'moodle,public'; -- Optional, if you wish to use a custom schema.
f834a8f5 323 You can set these options against the database or the moodle user who connects.

324* Some form elements have been refined to better support right-to-left languages. In RTL,
325 most fields should not have their direction flipped, a URL, a path to a file, a number, ...
326 are always displayed LTR. Input fields and text areas now will best guess whether they
327 should be forced to be displayed in LTR based on the PARAM type associated with it. You
328 can call $mform->setForceLtr($elementName, true/false) on some form fields to manually
329 set the value.

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

340* The first parameter $eventdata of both message_send() and \core\message\manager::send_message() should
341 be \core\message\message. Use of stdClass is deprecated.
342* The message_sent event now expects other[courseid] to be always set, exception otherwise. For BC with contrib code,
343 message_sent::create_from_ids() will show a debugging notice if the \core\message\message being sent is missing
344 the courseid property, defaulting to SITEID automatically. In Moodle 3.6 (MDL-55449) courseid will be fully mandatory
345 for all messages sent.
d6a25bc4 346* The send_confirmation_email() function has a new optional parameter $confirmationurl to provide a different confirmation URL.
bb316e07
JD
347* Introduced a new hook for plugin developers:
348 - <component>_course_module_background_deletion_recommended()
349 This hook should be used in conjunction with the existing '<component>_pre_course_module_delete($mod)'. It must
350 return a boolean and is called by core to check whether a plugin's implementation of
351 <component>_pre_course_module_deleted($mod) will take a long time. A plugin should therefore only implement this
352 function if it also implements <component>_pre_course_module_delete($mod).
353 An example in current use is recyclebin, which performs what can be a lengthy backup process in
354 tool_recyclebin_pre_course_module_delete. The recyclebin, if enabled, now returns true in its implementation of
355 tool_recyclebin_course_module_background_deletion_recommended(), to indicate to core that the deletion (and
356 execution of tool_recyclebin_pre_course_module_delete) should be handled with an adhoc task, meaning it will not
357 occur in real time.

436 __construct() for the constructor. Calling parent constructors by the class
437 name will display debugging message. Incorrect: parent::moodleform(),
438 correct: parent::__construct()
439 * All form elements have also changed the constructor syntax. No changes are
440 needed for using form elements, however if plugin defines new form element it
441 needs to use correct syntax. For example, incorrect: parent::HTML_QuickForm_input(),
442 HTML_QuickForm_input::HTML_QuickForm_input(), $this->HTML_QuickForm_input().
443 Correct: HTML_QuickForm_input::__construct() or parent::__construct().

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

661* For 3rd party plugin specific environment.xml files, it's now possible to specify version independent checks by using the
662 <PLUGIN name="component_name"> tag instead of the version dependent <MOODLE version="x.y"> one. If the PLUGIN tag is used any
663 Moodle specific tags will be ignored.
3451a51c 664* html_table: new API for adding captions to tables (new field, $table->caption) and subsequently hiding said captions from sighted users using accesshide (enabled using $table->captionhide).

665* The authorization procedure in the mdeploy.php script has been improved. The script
666 now relies on the main config.php when deploying an available update.
45a1a16b 667* sql_internal_reader and sql_select_reader interfaces have been deprecated in favour of sql_internal_table_reader
9fe26fb8 668 and sql_reader which use iterators to be more memory efficient.

DM
669* $CFG->enabletgzbackups setting has been removed as now backups are stored internally using .tar.gz format by default, you can
670 set $CFG->usezipbackups to store them in zip format. This does not affect the restore process, which continues accepting both.
9bcb0ba8
DM
671* Added support for custom string manager implementations via $CFG->customstringmanager
672 directive in the config.php. See MDL-49361 for details.
70be2642 673* Add new make_request_directory() for creation of per-request files.
b7067f06
AN
674* Added generate_image_thumbnail_from_string. This should be used instead of generate_image_thumbnail when the source is a string.
675 This prevents the need to write files to disk unnecessarily.
676* Added generate_image_thumbnail to stored_file class. This should be used when generating thumbnails for stored files.
677 This prevents the need to write files to disk unnecessarily.
3004a923 678* Removed pear/HTTP/WebDav. See MDL-49534 for details.

692* Gradebook grade category option "aggregatesubcats" has been removed completely.
693 This means that the database column is removed, the admin settings are removed and
694 the properties from the grade_category object have been removed. If any courses were
695 found to be using this setting, a warning to check the grades will be shown in the
696 course grader report after upgrading the site. The same warning will be shown on
697 courses restored from backup that had this setting enabled (see MDL-47503).
4051685b 698* lib/excelllib.class.php has been updated. The class MoodleExcelWorkbook will now only produce excel 2007 files.

SH
699* renderers: We now remove the suffix _renderable when looking for a render method for a renderable.
700 If you have a renderable class named like "blah_renderable" and have a method on a renderer named "render_blah_renderable"
701 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 702* New functions get_course_and_cm_from_cmid($cmorid, $modulename) and
703 get_course_and_cm_from_instance($instanceorid, $modulename) can be used to
704 more efficiently load these basic data objects at the start of a script.
705* New function cm_info::create($cm) can be used when you need a cm_info
706 object, but have a $cm which might only be a standard database record.
061e6b28 707* $CFG->enablegroupmembersonly no longer exists.

708* Scheduled tasks have gained support for syntax to introduce variability when a
709 task will run across installs. When a when hour or minute are defined as 'R'
710 they will be installed with a random hour/minute value.

711* Several classes grade_edit_tree_column_xxx were removed since grades setup page
712 has been significantly changed. These classes should not be used outside of
713 gradebook or developers can copy them into their plugins from 2.7 branch.

714* Google APIs Client Library (lib/google/) has been upgraded to 1.0.5-beta and
715 API has changed dramatically without backward compatibility. Any code accessing
716 it must be amended. It does not apply to lib/googleapi.php. See MDL-47297

8d1f33e1 800* Conditional availability API has moved and changed. The condition_info class is
801 replaced by \core_availability\info_module, and condition_info_section by
802 \core_availability\info_section. (Code that uses the old classes will generally
803 still work.)
804* coursemodule_visible_for_user() has been deprecated but still works - replaced
805 by a new static function \core_availability\info_module::is_user_visible()
806* cm_info::is_user_access_restricted_by_conditional_access has been deprecated
807 but still works (it has never done what its name suggests, and is
808 unnecessary).
809* cm_info and section_info property showavailability has been deprecated, but
810 still works (with the caveat that this information is now per-user).
811* cm_info and section_info properties availablefrom and availableuntil have been

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

851 get_plugin_list(), get_plugin_list_with_class(), get_plugin_directory(), normalize_component(),
852 get_component_directory() and get_plugin_list_with_file(). The names of the new methods are
853 exactly the same, the only differences are that core_component::get_plugin_types() now always returns
854 full paths and core_component::get_plugin_list() does not accept empty parameter any more.
d534708f 855* Use core_text::* instead of textlib:: and also core_collator::* instead of collatorlib::*.
af578aec 856* Use new function moodleform::mock_submit() to simulate form submission in unit tests (backported).

858* MS SQL Server drivers are now using NVARCHAR(MAX) instead of NTEXT and VARBINARY(MAX) instead of IMAGE,
859 this change should be fully transparent and it should help significantly with add-on compatibility.

860* The string manager classes were renamed. Note that they should not be modified or used directly,
861 always use get_string_manager() to get instance of the string manager.

ac2b2713 868* Subplugins are supported in admin tools and local plugins.
71ab7e51 869* file_packer/zip_packer API has been modified so that key functions support a new file_progress interface
870 to report progress during long operations. Related to this, zip_archive now supports an estimated_count()
871 function that returns an approximate number of entries in the zip faster than the count() function.
d872881f 872* Class cm_info no longer extends stdClass. All properties are read-only and calculated on first request only.
44ddd2a1 873* Class course_modinfo no longer extends stdClass. All properties are read-only.
64501eee

874* Database fields modinfo and sectioncache in table course are removed. Application cache core/coursemodinfo
875 is used instead. Course cache is still reset, rebuilt and retrieved using function rebuild_course_cache() and
876 get_fast_modinfo(). Purging all caches and every core upgrade purges course modinfo cache as well.
877 If function get_fast_modinfo() is called for multiple courses make sure to include field cacherev in course
878 object.

879* Internal (noreply and support) user support has been added for sending/receiving message.
880 Use core_user::get_noreply_user() and core_user::get_support_user() to get noreply and support user's respectively.
881 Real users can be used as noreply/support users by setting $CFG->noreplyuserid and $CFG->supportuserid
137885b7 882* New function readfile_allow_large() in filelib.php for use when very large files may need sending to user.

5fed8433 887* $USER->password field is intentionally unset so that session data does not contain password hashes.
38fc0130 888* Use core_shutdown_manager::register_function() instead of register_shutdown_function().
c858655d 889* New file packer for .tar.gz files; obtain by calling get_file_packer('application/x-gzip'). Intended initially
890 for use in backup/restore only, as there are limitations on supported filenames. Also new packer for
891 backups which supports both compression formats; get_file_packer('application/vnd.moodle.backup').
892* New optional parameter to stored_file::get_content_file_handle to open file handle with 'gzopen' instead
893 of 'fopen' to read gzip-compressed files if required.
6c679d15 894* update_internal_user_password() and setnew_password_and_mail() now trigger user_updated event.

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

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

1050* The database drivers (moodle_database and subclasses) aren't using anymore the ::columns property
1051 for caching database metadata. MUC (databasemeta) is used instead. Any custom DB driver should
1052 apply for that change.

1053* The cron output has been changed to include time and memory usage (see cron_trace_time_and_memory()),
1054 so any custom utility relying on the old output may require modification.

DW
1055* Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
1056 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
1057 an option for 0 bytes. Existing code that was replacing the 0 option in the return
1058 from this function with a more sensible message, can now use the return from this function directly.

1066* The function delete_course_module was deprecated and has been replaced with
1067 course_delete_module. The reason for this was because the function delete_course_module
1068 only partially deletes data, so wherever it was called extra code was needed to
1069 perform the whole deletion process. The function course_delete_module now takes care
1070 of the whole process.

1071* curl::setopt() does not accept constant values any more. As it never worked properly,

1073 corresponding to the curl constant name.

1074* Function get_users_listing now return list of users except guest and deleted users. Previously
1075 deleted users were excluded by get_users_listing. As guest user is not expected while browsing users,
1076 and not included in get_user function, it will not be returned by get_users_listing.

1079* The signature of the add() method of classes implementing the parentable_part_of_admin_tree
1080 interface (such as admin_category) has been extended. The new parameter allows the caller
1081 to prepend the new node before an existing sibling in the admin tree.

1089 in lib/coursecatlib.php, functions responsible for rendering courses and categories lists are

1099* Additional (optional) param $onlyactive has been added to get_enrolled_users, count_enrolled_users
1100 functions to get information for only active (excluding suspended enrolments) users. Included two
1101 helper functions extract_suspended_users, get_suspended_userids to extract suspended user information.
e87214bd 1102* The core_plugin_manager class now provides two new helper methods for getting information
d7d48b40 1103 about known plugins: get_plugins_of_type() and get_subplugins_of_plugin().
e87214bd 1104* The get_uninstall_url() method of all subclasses of \core\plugininfo\base class is now expected
73658371
DM
1105 to always return moodle_url. Subclasses can use the new method is_uninstall_allowed()
1106 to control the availability of the 'Uninstall' link at the Plugins overview page (previously
1107 they would do it by get_uninstall_url() returning null). By default, URL to a new general plugin
1108 uninstall tool is returned. Unless the plugin type needs extra steps that can't be handled by
1109 plugininfo_xxx::uninstall() method or xmldb_xxx_uninstall() function, this default URL should
1110 satisfy all plugin types.
