690a55f6 1This files describes API changes in core libraries and APIs,
ee362526 2information provided here is intended especially for developers.
1cb5c7b3 3
b91ddd16 4=== 3.7 ===
9df03b19 5* Nodes in the navigation api can have labels for each group. See set/get_collectionlabel().
b91ddd16 6* The method core_user::is_real_user() now returns false for userid = 0 parameter
cabdadf3
SA
7* 'mform1' dependencies (in themes, js...) will stop working because a randomly generated string has been added to the id
8attribute on forms to avoid collisions in forms loaded in AJAX requests.
b51b6969
AN
9* A new method to allow queueing or rescheduling of an existing scheduled task was added. This allows an existing task
10 to be updated or queued as required. This new functionality can be found in \core\task\manager::reschedule_or_queue_adhoc_task.
ef96eb02 11* Icons are displayed for screen readers unless they have empty alt text (aria-hidden). Do not provide an icon with alt text immediately beside an element with exactly the same text.
d940855f 12* admin_settingpage has a new function hide_if(), modeled after the same functionality in the forms library. This allows admin settings to be dynamically hidden based on the values of other settings.
9f3bf966
AN
13* The \core_rating provider's get_sql_join function now accepts an optional $innerjoin parameter.
14 It is recommended that privacy providers using this function call rewrite any long query into a number of separate
15 calls to add_from_sql for improved performance, and that the new argument is used.
16 This will allow queries to remain backwards-compatible with older versions of Moodle but will have significantly better performance in version supporting the innerjoin parameter.
4bbec310
AA
17* /message/defaultoutputs.php file and admin_page_defaultmessageoutputs class have been deprecated
18 and all their settings moved to admin/message.php (see MDL-64495). Please use admin_page_managemessageoutputs class instead.
545e2abb
SL
19* A new parameter $lang has been added to mustache_template_source_loader->load_with_dependencies() method
20 so it is possible for Mustache to request string in a specific language.
05a5d547 21* Behat timeout constants behat_base::TIMEOUT, EXTENDED_TIMEOUT, and REDUCED_TIMEOUT have been
22 deprecated. Please instead use the functions behat_base::get_timeout(), get_extended_timeout(),
23 and get_reduced_timeout(). These allow for timeouts to be increased by a setting in config.php.
e0695f87
JL
24* The $draftitemid parameter of file_save_draft_area_files() function now supports the constant IGNORE_FILE_MERGE:
25 When the parameter is set to that constant, the function won't process file merging, keeping the original state of the file area.
5ba12283
JL
26* Introduced new callback for plugin developers '<component>_pre_processor_message_send($procname, $proceventdata)':
27 This will allow any plugin to manipulate messages or notifications before they are sent by a processor (email, mobile...)
f7b52799 28* New capability 'moodle/category:viewcourselist' in category context that controls whether user is able to browse list of courses
beff3806
MG
29 in this category. To work with list of courses use API methods in core_course_category and also 'course' form element.
30* It is possible to pass additional conditions to get_courses_search();
31 core_course_category::search_courses() now allows to search only among courses with completion enabled.
bf9f2555 32* Add support for a new xxx_after_require_login callback
734b198f
SA
33* A new conversation type has been created for self-conversations. During the upgrading process:
34 - Firstly, the existing self-conversations will be starred and migrated to the new type, removing the duplicated members in the
35 message_conversation_members table.
36 - Secondly, the legacy self conversations will be migrated from the legacy 'message_read' table. They will be created using the
37 new conversation type and will be favourited.
38 - Finally, the self-conversations for all remaining users without them will be created and starred.
39Besides, from now, a self-conversation will be created and starred by default to all the new users (even when $CFG->messaging
40is disabled).
b858b161
JP
41* New optional parameter $throwexception for \get_complete_user_data(). If true, an exception will be thrown when there's no
42 matching record found or when there are multiple records found for the given field value. If false, it will simply return false.
43 Defaults to false when not set.
cb28132d 44* Exposed submit button to allow custom styling (via customclassoverride variable) which can override btn-primary/btn-secondary classes
b91ddd16 45
437ffc9f 46=== 3.6 ===
47
883f6555
AN
48* A new token-based version of pluginfile.php has been added which can be used for out-of-session file serving by
49 setting the `$includetoken` parameter to true on the `moodle_url::make_pluginfile_url()`, and
50 `moodle_url::make_file_url()` functions.
51* The following picture functions have been updated to support use of the new token-based file serving:
52 - print_group_picture
53 - get_group_picture_url
88d89512
AN
54* The `user_picture` class has a new public `$includetoken` property which can be set to make use of the new token-based
55 file serving.
9411beb3 56* Custom AJAX handlers for the form autocomplete fields can now optionally return string in their processResults()
2dd33840 57 callback. If a string is returned, it is displayed instead of the list of suggested items. This can be used, for
9411beb3 58 example, to inform the user that there are too many items matching the current search criteria.
f8d15c66 59* The form element 'htmleditor' has been deprecated. Please use the 'editor' element instead.
350d7b06 60* The print_textarea() function has been deprecated. Please use $OUTPUT->print_textarea() instead.
437ffc9f 61* The following functions have been finally deprecated and can not be used any more:

106 - I set the field "<field_string>" to multiline
107 - I follow "<link_string>"" in the open menu
02fda279
VDF
108* The following behat steps have been deprecated, please do not use these step definitions any more:
109 - behat_navigation.php: i_navigate_to_node_in()
110 - theme/boost/tests/behat/behat_theme_boost_behat_navigation.php: i_navigate_to_node_in()
111 Use one of the following steps instead:
112 - I navigate to "PATH > ITEM" in current page administration
113 - I navigate to "PATH > ITEM" in site administration
114 - I navigate to course participants
115 - I navigate to "TAB1 > TAB2" in the course gradebook
02fda279
VDF
116 If some items are not available without Navigation block at all, one can use combination of:
117 - I add the "Navigation" block if not present
118 - I click on "LINK" "link" in the "Navigation" "block"
4f06a977
EL
119* The core\session\util class has been removed. This contained one function only used by the memcached class which has
120 been moved there instead (connection_string_to_memcache_servers).
512a1d31 121* Removed the lib/password_compat/lib/password.php file.
5454e72c
AG
122* The eventslib.php file has been deleted and its functions have been moved to deprecatedlib.php. The affected functions are:
123 - events_get_cached()
124 - events_uninstall()
125 - events_cleanup()

127 - events_get_handlers()
f7115c2e
SR
128* coursecat::get() now has optional $user parameter.
129* coursecat::is_uservisible() now has optional $user parameter.
2dd33840 130* Removed the lib/form/submitlink.php element which was deprecated in 3.2.
afa3e0ff
DM
131* The user_selector classes do not support custom list of extra identity fields any more. They obey the configured user
132 policy and respect the privacy setting made by site administrators. The list of user identifiers should never be
133 hard-coded. Instead, the setting $CFG->showuseridentity should be always respected, which has always been the default
134 behaviour (MDL-59847).
cc4952e9
AG
135* The function message_send() in messagelib.php will now only take the object \core\message\message as a parameter.
136* The method message_sent::create_from_ids() parameter courseid is now required. A debugging
137 message was previously displayed, and the SITEID was used, when not provided.
138* The method \core\message\manager::send_message() now only takes the object \core\message\message as the first parameter.
df536ab1 139* Following functions have been deprecated, please use get_roles_used_in_context.
140 - get_roles_on_exact_context()
141 - get_roles_with_assignment_on_context()

c353ad20
JP
143 - file_copy_file_to_file_area()
144 - file_merge_draft_areas()
145 - file_replace_file_area_in_text()
146 - extract_draft_file_urls_from_text()
442f12f8
MG
147* Class coursecat is now alias to autoloaded class core_course_category, course_in_list is an alias to
148 core_course_list_element, class coursecat_sortable_records is deprecated without replacement.
69781cda
JP
149* \core_user_external::create_users() and \core_user_external::update_users() can now accept more user profile fields so user
150 creation/update via web service can now be very similar to the edit profile page's functionality. The new fields that have been
151 added are:
152 - maildisplay
153 - interests
154 - url
155 - icq
156 - skype
157 - aim
158 - yahoo
159 - msn
160 - institution
161 - department
162 - phone1
163 - phone2
164 - address
1d049e08
JC
165* New function mark_user_dirty() must be called after changing data that gets cached in user sessions. Examples:
166 - Assigning roles to users.
167 - Unassigning roles from users.
bdc51136
DM
168 - Enrolling users into courses.
169 - Unenrolling users from courses.
5290d060
SA
170* New optional parameter $context for the groups_get_members_join() function and ability to filter users that are not members of
171any group. Besides, groups_get_members_ids_sql, get_enrolled_sql and get_enrolled_users now accepts -1 (USERSWITHOUTGROUP) for
172the groupid field.
1afbb97b
AO
173* Added $CFG->conversionattemptlimit setting to config.php allowing a maximum number of retries before giving up conversion
174 of a given document by the assignfeedback_editpdf\task\convert_submissions task. Default value: 3.
beeadbf7
MN
175* The following events have been deprecated and should not be used any more:
176 - message_contact_blocked
177 - message_contact_unblocked
178 The reason for this is because you can now block/unblock users without them necessarily being a contact. These events
179 have been replaced with message_user_blocked and message_user_unblocked respectively.
14de10c4
MN
180* The event message_deleted has been changed, it no longer records the value of the 'useridto' due to
181 the introduction of group messaging. Please, if you have any observers or are triggering this event
182 in your code you will have to make some changes!
5d7a9ea6
MN
183* The gradebook now supports the ability to accept files as feedback. This can be achieved by adding
184 'feedbackfiles' to the $grades parameter passed to grade_update().
185 For example -
186 $grades['feedbackfiles'] = [
187 'contextid' => 1,
188 'component' => 'mod_xyz',
189 'filearea' => 'mod_xyz_feedback',
190 'itemid' => 2
191 ];
192 These files will be then copied to the gradebook file area.
32791416
SA
193* Allow users to choose who can message them for privacy reasons, with a 'growing circle of contactability':
194 - Added $CFG->messagingallusers, for enabling messaging to all site users. Default value: 0.
195 When $CFG->messagingallusers = false users can choose being contacted by only contacts or contacts and users sharing a course with them.
196 In that case, the default user preference is MESSAGE_PRIVACY_COURSEMEMBER (users sharing a course).
197 When $CFG->messagingallusers = true users have a new option for the privacy messaging preferences: "Anyone on the site". In that case,
198 the default user preference is MESSAGE_PRIVACY_SITE (all site users).
199 - Added $CFG->keepmessagingallusersenabled setting to config.php to force enabling $CFG->messagingallusers during the upgrading process.
200 Default value: 0.
201 When $CFG->keepmessagingallusersenabled is set to true, $CFG->messagingallusers will be also set to true to enable messaging site users.
202 However, when it is empty, $CFG->messagingallusers will be disabled during the upgrading process, so the users will only be able to
203 message contacts and users sharing a course with them.
d5adb60f
MP
204* There has been interface and functional changes to admin_apply_default_settings() (/lib/adminlib.php). The function now takes two
205 additional optional parameters, $admindefaultsettings and $settingsoutput. It also has a return value $settingsoutput.
206 The function now does not need to be called twice to ensure all default settings are set. Instead the function calls itself recursively
207 until all settings have been set. The additional parameters are used recursively and shouldn't be need to be explicitly passed in when calling
208 the function from other parts of Moodle.
209 The return value: $settingsoutput is an array of setting names and the values that were set by the function.
160e77f9 210* Webservices no longer update the lastaccess time for a user in a course. Call core_course_view_course() manually if needed.
0616f045 211* A new field has been added to the context table. Please ensure that any contxt preloading uses get_preload_record_columns_sql or get_preload_record_columns to fetch the list of columns.

521252d6
DM
213=== 3.5 ===
214
4f41ae27
DM
215* There is a new privacy API that every subsystem and plugin has to implement so that the site can become GDPR
216 compliant. Plugins use this API to report what information they store or process regarding users, and provide ability
217 to export and delete personal data. See https://docs.moodle.org/dev/Privacy_API for guidelines on how to implement the
218 privacy API in your plugin.
cd305dc2 219* The cron runner now sets up a fresh PAGE and OUTPUT between each task.
76f8b361
EL
220* The core_renderer methods notify_problem(), notify_success(), notify_message() and notify_redirect() that were
221 deprecated in Moodle 3.1 have been removed. Use \core\notification::add(), or \core\output\notification as required.
521252d6
DM
222* The maximum supported precision (the total number of digits) for XMLDB_TYPE_NUMBER ("number") fields raised from 20 to
223 38 digits. Additionally, the whole number part (precision minus scale) must not be longer than the maximum length of
224 integer fields (20 digits). Note that PHP floats commonly support precision of roughly 15 digits only (MDL-32113).
0e68db9e
EL
225* Event triggering and event handlers:
226 - The following events, deprecated since moodle 2.6, have been finally removed: groups_members_removed,
227 groups_groupings_groups_removed, groups_groups_deleted, groups_groupings_deleted.
56c9d666
JP
228* The following functions have been finally deprecated and can not be used any more:
229 - notify()
54a099e9
EL
230* XMLDB now validates the PATH attribute on every install.xml file. Both the XMLDB editor and installation will fail
231 when a problem is detected with it. Please ensure your plugins contain correct directory relative paths.
caae0820 232* Add recaptchalib_v2.php for support of reCAPTCHA v2.
1727c939
MG
233* Plugins can define class 'PLUGINNAME\privacy\local\sitepolicy\handler' if they implement an alternative mechanisms for
234 site policies managements and agreements. Administrators can define which component is to be used for handling site
235 policies and agreements. See https://docs.moodle.org/dev/Site_policy_handler
0bdc5785
DM
236* Scripts can define a constant NO_SITEPOLICY_CHECK and set it to true before requiring the main config.php file. It
237 will make the require_login() skipping the test for the user's policyagreed status. This is useful for plugins that
238 act as a site policy handler.
c2e97077
DM
239* There is a new is_fulltext_search_supported() DML function. The default implementation returns false. This function
240 is used by 'Simple search' global search engine to determine if the database full-text search capabilities can be used.
3cfbce12
JP
241* The following have been removed from the list of core subsystems:
242 - core_register
243 - core_publish
3127fe10
MG
244 Following this change, \core_register_renderer and \core_publish_renderer have been removed and their methods have been
245 moved to \core_admin_renderer and \core_course_renderer respectively.
521252d6 246
8cf36e9c 247=== 3.4 ===
521252d6 248
d3882ea4 249* oauth2_client::request method has an extra parameter to specify the accept header for the response (MDL-60733)
f83d212b
EL
250* The following functions, previously used (exclusively) by upgrade steps are not available
251 anymore because of the upgrade cleanup performed for this version. See MDL-57432 for more info:
252 - upgrade_mimetypes()
253 - upgrade_fix_missing_root_folders_draft()
254 - upgrade_minmaxgrade()
255 - upgrade_course_tags()
256
8cf36e9c
DM
257* Added new moodleform element 'filetypes' and new admin setting widget 'admin_setting_filetypes'. These new widgets
258 allow users to define a list of file types; either by typing them manually or selecting them from a list. The widgets
259 directly support the syntax used to feed the 'accepted_types' option of the filemanager and filepicker elements. File
260 types can be specified as extensions (.jpg or just jpg), mime types (text/plain) or groups (image).
e705e69e
TL
261* Removed accesslib private functions: load_course_context(), load_role_access_by_context(), dedupe_user_access() (MDL-49398).
262* Internal "accessdata" structure format has changed to improve ability to perform role definition caching (MDL-49398).
263* Role definitions are no longer cached in user session (MDL-49398).
0f398b50
JL
264* External function core_group_external::get_activity_allowed_groups now returns an additional field: canaccessallgroups.
265 It indicates whether the user will be able to access all the activity groups.
bef201c7 266* file_get_draft_area_info does not sum the root folder anymore when calculating the foldercount.
6c8e25fa
DM
267* The moodleform element classes can now optionally provide a public function validateSubmitValue(). This method can be
268 used to perform implicit validation of submitted values - without the need to explicitly add the validation rules to
269 every form. The method should accept a single parameter with the submitted value. It should return a string with the
270 eventual validation error, or an empty value if the validation passes.
3b1eba06 271* New user_picture attribute $includefullname to determine whether to include the user's full name with the user's picture.
fd0a43be
JP
272* Enrol plugins which provide enrolment actions can now declare the following "data-action" attributes in their implementation of
273 enrol_plugin::get_user_enrolment_actions() whenever applicable:
274 * "editenrolment" - For editing a user'e enrolment details. Defined by constant ENROL_ACTION_EDIT.
275 * "unenrol" - For unenrolling a student. Defined by constant ENROL_ACTION_UNENROL.
276 These attributes enable enrol actions to be rendered via modals. If not added, clicking on the enrolment action buttons will still
277 redirect the user to the appropriate enrolment action page. Though optional, it is recommended to add these attributes for a
278 better user experience when performing enrol actions.
4047fccb
JP
279* The enrol_plugin::get_user_enrolment_actions() implementations for core enrol plugins have been removed and moved to
280 the parent method itself. New enrol plugins don't have to implement get_user_enrolment_actions(), but just need to
281 make sure that they override:
282 - enrol_plugin::allow_manage(), and/or
283 - enrol_plugin::allow_unenrol_user() or enrol_plugin::allow_unenrol()
284 Existing enrol plugins that override enrol_plugin::get_user_enrolment_actions() don't have to do anything, but can
285 also opt to remove their own implementation of the method if they basically have the same logic as the parent method.
bb1c6f85
JP
286* New optional parameter $enrolid for the following functions:
287 - get_enrolled_join()
288 - get_enrolled_sql()
289 - get_enrolled_with_capabilities_join()
290 Setting this parameter to a non-zero value will add a condition to the query such that only users that were enrolled
291 with this enrolment method will be returned.
198d7291
JP
292* New optional parameter 'closeSuggestionsOnSelect' for the enhance() function for form-autocomplete. Setting this to true will
293 close the suggestions popup immediately after an option has been selected. If not specified, it defaults to true for single-select
294 elements and false for multiple-select elements.
4d068a67 295* user_can_view_profile() now also checks the moodle/user:viewalldetails capability.
237efd4f
JP
296* The core/modal_confirm dialogue has been deprecated. Please use the core/modal_save_cancel dialogue instead. Please ensure you
297 update to use the ModalEvents.save and ModalEvents.cancel events instead of their yes/no counterparts.
93b47710
MN
298* Instead of checking the 'moodle/course:viewparticipants' and 'moodle/site:viewparticipants' capabilities use the
299 new functions course_can_view_participants() and course_require_view_participants().
b1eb6dd7 300* $stored_file->add_to_curl_request() now adds the filename to the curl request.
b58764ff
JO
301* The option for Login HTTPS (authentication-only SSL) has been removed
302* $CFG->loginhttps is now deprecated, do not use it.
4b501ec9 303* $PAGE->https_required and $PAGE->verify_https_required() are now deprecated. They are no longer used and will throw a coding_exception.
672f4836 304* $CFG->httpswwwroot is now deprecated and will always result in the same value as wwwroot.
a63cd3e2
AH
305* Added function core_role_set_view_allowed() to check if a user should be able to see a given role.
306 This should be checked whenever displaying a list of roles to a user, however, core_role_set_assign_allowed may need to override it
307 in some cases.
64cd4596 308* Deprecated allow_override, allow_assign and allow_switch and replaced with core_role_set_*_allowed to avoid function names conflicting.
8cf36e9c 309
67bebb69
IA
310=== 3.3.1 ===
311
312* ldap_get_entries_moodle() now always returns lower-cased attribute names in the returned entries.
313 It was suppposed to do so before, but it actually didn't.
314
3be09119 315=== 3.3 ===
1cb5c7b3 316
69cdead3
DP
317* Behat compatibility changes are now being documented at
318 https://docs.moodle.org/dev/Acceptance_testing/Compatibility_changes
55946a89
EL
319* PHPUnit's bootstrap has been changed to use HTTPS wwwroot (https://www.example.com/moodle) from previous HTTP version. Any
320 existing test expecting the old HTTP URLs will need to be switched to the new HTTPS value (reference: MDL-54901).

321* The information returned by the idp list has changed. This is usually only rendered by the login page and login block.
322 The icon attribute is removed and an iconurl attribute has been added.
151b0f94 323* Support added for a new type of external file: FILE_CONTROLLED_LINK. This is an external file that Moodle can control
141ee541 324 the permissions. Moodle makes files read-only but can grant temporary write access.

325 When accessing a URL, the info from file_browser::get_file_info will be checked to determine if the user has write access,
326 if they do - the remote file will have access controls set to allow editing.

327* The method moodleform::after_definition() has been added and can now be used to add some logic
328 to be performed after the form's definition was set. This is useful for intermediate subclasses.

329* Moodle has support for font-awesome icons. Plugins should use the xxx_get_fontawesome_icon_map callback
330 to map their custom icons to one from font-awesome.
331* $OUTPUT->pix_url() has been deprecated because it is was used mostly to manually generate image tags for icons.
332 We now distinguish between icons and "small images". The difference is that an icon does not have to be rendered as an image tag
333 with a source. It is OK to still have "small images" - if this desired use $OUTPUT->image_icon() and $OUTPUT->image_url(). For
334 other uses - use $OUTPUT->pix_icon() or the pix helper in mustache templates {{#pix}}...{{/pix}}
c266d256 335 For other valid use cases use $OUTPUT->image_url().
3e6adcd6 336* Activity icons have been split from standard icons. Use $OUTPUT->image_icon instead of $OUTPUT->pix_icon for these
c2dde7ee 337 type of icons (the coloured main icon for each activity).

524 message_sent::create_from_ids() will show a debugging notice if the \core\message\message being sent is missing
525 the courseid property, defaulting to SITEID automatically. In Moodle 3.6 (MDL-55449) courseid will be fully mandatory
526 for all messages sent.

JD
528* Introduced a new hook for plugin developers:
529 - <component>_course_module_background_deletion_recommended()
530 This hook should be used in conjunction with the existing '<component>_pre_course_module_delete($mod)'. It must
531 return a boolean and is called by core to check whether a plugin's implementation of
532 <component>_pre_course_module_deleted($mod) will take a long time. A plugin should therefore only implement this
533 function if it also implements <component>_pre_course_module_delete($mod).
534 An example in current use is recyclebin, which performs what can be a lengthy backup process in
535 tool_recyclebin_pre_course_module_delete. The recyclebin, if enabled, now returns true in its implementation of
536 tool_recyclebin_course_module_background_deletion_recommended(), to indicate to core that the deletion (and
537 execution of tool_recyclebin_pre_course_module_delete) should be handled with an adhoc task, meaning it will not
538 occur in real time.

979* mod_page\event\instances_list_viewed has been deprecated. Please use mod_page\event\course_module_instance_list_viewed instead.
1f1a8f03 980* The constants FRONTPAGECOURSELIST, FRONTPAGETOPICONLY & FRONTPAGECOURSELIMIT have been removed.
8d1f33e1 981* Conditional availability API has moved and changed. The condition_info class is
982 replaced by \core_availability\info_module, and condition_info_section by
983 \core_availability\info_section. (Code that uses the old classes will generally
984 still work.)
985* coursemodule_visible_for_user() has been deprecated but still works - replaced
986 by a new static function \core_availability\info_module::is_user_visible()
987* cm_info::is_user_access_restricted_by_conditional_access has been deprecated
988 but still works (it has never done what its name suggests, and is
989 unnecessary).
990* cm_info and section_info property showavailability has been deprecated, but
991 still works (with the caveat that this information is now per-user).
992* cm_info and section_info properties availablefrom and availableuntil have been
993 deprecated and always return zero (underlying data doesn't have these values).
994* section_info property groupingid has been deprecated and always returns zero,
995 same deal.
07e78d93
DP
996* Various cm_info methods have been deprecated in favour of their read-only properties (get_url(), get_content(), get_extra_classes(),
997 get_on_click(), get_custom_data(), get_after_link, get_after_edit_icons)
af64bc61 998* The ajaxenabled function has been deprecated and always returns true. All code should be fully functional in Javascript.
52dc1de7 999* count_login_failures() has been deprecated, use user_count_login_failures() instead. Refer MDL-42891 for details.
c4b0d6dc 1000
8d1f33e1 1001Conditional availability (activities and sections):
1002* New conditional availability API in /availability, including new availability
1003 condition plugins in /availability/condition. The new API is very similar with
1004 regard to checking availability, but any code that modifies availability settings
1005 for an activity or section is likely to need substantial changes.

AN
1007YUI:
1008 * The lightbox attribute for moodle-core-notification-dialogue has been
1009 deprecated and replaced by the modal attribute. This was actually
1010 changed in Moodle 2.2, but has only been marked as deprecated now. It
1011 will be removed in Moodle 2.9.
0860dd78
AN
1012 * When destroying any type of dialogue based on moodle-core-notification, the relevant content is also removed from
1013 the DOM. Previously it was left orphaned.
5947ab33 1014

1015JavaSript:
1016 * The findChildNodes global function has been deprecated. Y.all should
1017 be used instead.
1d98ca14
AN
1018 * The callback argument to confirm_action and M.util.show_confirm_dialog has been deprecated. If you need to write a
1019 confirmation which includes a callback, please use moodle-core-notification-confirmation and attach callbacks to the
1020 events provided.
a4582a51 1021
9843e5ec 1022* New locking api and admin settings to configure the system locking type.
3b635513
DM
1023* New "Time spent waiting for the database" performance metric displayed along with the
1024 other MDL_PERF vars; the change affects both the error logs and the vars displayed in
1025 the page footer.

9e19a0f0 1029=== 2.6 ===
8e8891b7 1030
cc8fecb5 1031* Use new methods from core_component class instead of get_core_subsystems(), get_plugin_types(),
d0cac8b5
FM
1032 get_plugin_list(), get_plugin_list_with_class(), get_plugin_directory(), normalize_component(),
1033 get_component_directory() and get_plugin_list_with_file(). The names of the new methods are
1034 exactly the same, the only differences are that core_component::get_plugin_types() now always returns
1035 full paths and core_component::get_plugin_list() does not accept empty parameter any more.
d534708f 1036* Use core_text::* instead of textlib:: and also core_collator::* instead of collatorlib::*.
af578aec 1037* Use new function moodleform::mock_submit() to simulate form submission in unit tests (backported).
85b38061 1038* New $CFG->localcachedir setting useful for cluster nodes. Admins have to update X-Sendfile aliases if used.
656250de
PS
1039* MS SQL Server drivers are now using NVARCHAR(MAX) instead of NTEXT and VARBINARY(MAX) instead of IMAGE,
1040 this change should be fully transparent and it should help significantly with add-on compatibility.
598a82c9
PS
1041* The string manager classes were renamed. Note that they should not be modified or used directly,
1042 always use get_string_manager() to get instance of the string manager.
aae18d2a 1043* The ability to use an 'insecure' rc4encrypt/rc4decrypt key has been removed.
96f81ea3
PS
1044* Use $CFG->debugdeveloper instead of debugging('', DEBUG_DEVELOPER).
1045* Use set_debugging(DEBUG_xxx) when changing debugging level for current request.
d55f05ef 1046* Function moveto_module() does not modify $mod argument and instead now returns the new module visibility value.
db5f2d33
DM
1047* Use behat_selectors::get_allowed_text_selectors() and behat_selectors::get_allowed_selectors() instead of
1048 behat_command::$allowedtextselectors and behat_command::$allowedselectors
ac2b2713 1049* Subplugins are supported in admin tools and local plugins.
71ab7e51 1050* file_packer/zip_packer API has been modified so that key functions support a new file_progress interface
1051 to report progress during long operations. Related to this, zip_archive now supports an estimated_count()
1052 function that returns an approximate number of entries in the zip faster than the count() function.
d872881f 1053* Class cm_info no longer extends stdClass. All properties are read-only and calculated on first request only.
44ddd2a1 1054* Class course_modinfo no longer extends stdClass. All properties are read-only.
64501eee
MG
1055* Database fields modinfo and sectioncache in table course are removed. Application cache core/coursemodinfo
1056 is used instead. Course cache is still reset, rebuilt and retrieved using function rebuild_course_cache() and
1057 get_fast_modinfo(). Purging all caches and every core upgrade purges course modinfo cache as well.
1058 If function get_fast_modinfo() is called for multiple courses make sure to include field cacherev in course
1059 object.
3bcf6b3c
RT
1060* Internal (noreply and support) user support has been added for sending/receiving message.
1061 Use core_user::get_noreply_user() and core_user::get_support_user() to get noreply and support user's respectively.
1062 Real users can be used as noreply/support users by setting $CFG->noreplyuserid and $CFG->supportuserid
137885b7 1063* New function readfile_allow_large() in filelib.php for use when very large files may need sending to user.
e87214bd 1064* Use core_plugin_manager::reset_caches() when changing visibility of plugins.
bde002b8
PS
1065* Implement new method get_enabled_plugins() method in subplugin info classes.
1066* Each plugin should include version information in version.php.
723a6e56 1067* Module and block tables do not contain version column any more, use get_config('xx_yy', 'version') instead.
5fed8433 1068* $USER->password field is intentionally unset so that session data does not contain password hashes.
38fc0130 1069* Use core_shutdown_manager::register_function() instead of register_shutdown_function().
c858655d 1070* New file packer for .tar.gz files; obtain by calling get_file_packer('application/x-gzip'). Intended initially
1071 for use in backup/restore only, as there are limitations on supported filenames. Also new packer for
1072 backups which supports both compression formats; get_file_packer('application/vnd.moodle.backup').
1073* New optional parameter to stored_file::get_content_file_handle to open file handle with 'gzopen' instead
1074 of 'fopen' to read gzip-compressed files if required.
6c679d15 1075* update_internal_user_password() and setnew_password_and_mail() now trigger user_updated event.
b2858b91 1076* Add thirdpartylibs.xml file to plugins that bundle any 3rd party libraries.
2dd8e935
DP
1077* New class introduced to help auto generate zIndex values for modal dialogues. Class "moodle-has-zindex"
1078 should set on any element which uses a non-default zindex and needs to ensure it doesn't show above a
1079 dialogue.
0c431257
PS
1080* $CFG->filelifetime is now used consistently for most file serving operations, the default was lowered
1081 to 6 hours from 24 hours because etags and x-sendfile support should make file serving less expensive.
d61d3e82
RT
1082* Date format locale charset for windows server will come from calendar type and for gregorian it will use
1083 lang file.
2d5c7d50
FM
1084* The library to interact with Box.net (class boxclient) is only compatible with their APIv1 which
1085 reaches its end of life on the 14th of Dec. You should migrate your scripts to make usage of the
1086 new class boxnet_client(). Note that the method names and return values have changed.
b404b1f4
AG
1087* Settings pages are now possible for Calendar type plugins. Calendar type plugins that require a settings page to
1088 work properly will need to set their requires version to a number that is equal to or grater than the 2.6.1 release version.
fb16acf2
DP
1089* The admin/tool/generator tool was overhauled to use testing data generators and the previous interface to create
1090 test data was removed (it was not working correctly anyway). If you were using this tool you will probably need to
1091 update your code.

1212Event triggering and event handlers:

1214 event classes and matching new event observers.
1215 * See http://docs.moodle.org/dev/Event_2 for more information.
861b0510

1231* The database drivers (moodle_database and subclasses) aren't using anymore the ::columns property
1232 for caching database metadata. MUC (databasemeta) is used instead. Any custom DB driver should
1233 apply for that change.
cedc656b
EL
1234* The cron output has been changed to include time and memory usage (see cron_trace_time_and_memory()),
1235 so any custom utility relying on the old output may require modification.
6b219310
DW
1236* Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
1237 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
1238 an option for 0 bytes. Existing code that was replacing the 0 option in the return
1239 from this function with a more sensible message, can now use the return from this function directly.
9a36be73 1240* Functions responsible for output in course/lib.php are deprecated, the code is moved to
b1c2fc65

1241 appropriate renderers: print_section(), print_section_add_menus(), get_print_section_cm_text(),

1245* zip_packer may create empty zip archives, there is a new option to ignore
1246 problematic files when creating archive
93cc145f
MN
1247* The function delete_course_module was deprecated and has been replaced with
1248 course_delete_module. The reason for this was because the function delete_course_module
1249 only partially deletes data, so wherever it was called extra code was needed to
1250 perform the whole deletion process. The function course_delete_module now takes care
1251 of the whole process.
91c8cf99
F
1252* curl::setopt() does not accept constant values any more. As it never worked properly,
1253 we decided to make the type check stricter. Now, the keys of the array pass must be a string
1254 corresponding to the curl constant name.
043f1005
RT
1255* Function get_users_listing now return list of users except guest and deleted users. Previously
1256 deleted users were excluded by get_users_listing. As guest user is not expected while browsing users,
1257 and not included in get_user function, it will not be returned by get_users_listing.

1259 MODNAME_dndupload_register callback instead.

1262 to prepend the new node before an existing sibling in the admin tree.

09ae7ee0

1270 in lib/coursecatlib.php, functions responsible for rendering courses and categories lists are
1271 moved to course/renderer.php. The following global functions are deprecated: make_categories_list(),

1287 to control the availability of the 'Uninstall' link at the Plugins overview page (previously
1288 they would do it by get_uninstall_url() returning null). By default, URL to a new general plugin
1289 uninstall tool is returned. Unless the plugin type needs extra steps that can't be handled by
1290 plugininfo_xxx::uninstall() method or xmldb_xxx_uninstall() function, this default URL should
1291 satisfy all plugin types.
