147a895a
PB
20* Plugins can now explicitly declare supported and incompatible Moodle versions in version.php
21 - $plugin->supported = [37,39];
22 supported takes an array of ascending numbers, that correspond to a range of branch numbers of supported versions, inclusive.
23 Moodle versions that are outside of this range will produce a message notifying at install time, but will allow for installation.
24 - $plugin->incompatible = 36;
25 incompatible takes a single int corresponding to the first incompatible branch. Any Moodle versions including and
26 above this will be prevented from installing the plugin, and a message will be given when attempting installation.
b2eec327 27* Added the <component>_bulk_user_actions() callback which returns a list of custom action_links objects
948a951a
AM

06299fc6 40* lib/outputrequirementslib::get_jsrev now is public, it can be called from other classes.
08fda3e0 41* H5P libraries have been moved from /lib/h5p to h5p/h5plib as an h5plib plugintype.
3180869e
MG
42* mdn-polyfills has been renamed to polyfills. The reason there is no polyfill from the MDN is
43 because there is no example polyfills on the MDN for this functionality.
4400ed3e
MN
44* AJAX pages can be called without requiring a session lock if they set READ_ONLY_SESSION to true, eg.
45 define('READ_ONLY_SESSION', true); Note - this also requires $CFG->enable_read_only_sessions to be set to true.
46* External functions can be called without requiring a session lock if they define 'readonlysession' => true in
47 db/services.php. Note - this also requires $CFG->enable_read_only_sessions to be set to true.
47f3fa13 48* database_manager::check_database_schema() now checks for missing and extra indexes.
5bf5a7aa 49* Implement a more direct xsendfile_file() method for an alternative_file_system_class
685fe080
AN
50* A new `dynamic` table interface has been defined, which allows any `flexible_table` to be converted into a table which
51 is updatable via ajax calls. See MDL-68495 and `\core_table\dynamic` for further information.

JP
69* New output component available: \core\output\checkbox_toggleall
70 - This allows developers to easily output groups of checkboxes that can be toggled by master controls in the form of a checkbox or
71 a button. Action elements which perform actions on the selected checkboxes can also be enabled/disabled depending on whether
72 at least a single checkbox item is selected or not.
c5681f7f 73* Final deprecation (removal) of the core/modal_confirm dialogue.

AN
79* It is now possible to use sub-directories for AMD modules.
80 The standard rules for Level 2 namespaces also apply to AMD modules.
81 The sub-directory used must be either an valid component, or placed inside a 'local' directory to ensure that it does not conflict with other components.
82
83 The following are all valid module names and locations in your plugin:
84 mod_forum/view: mod/forum/amd/src/view.js
85 mod_forum/local/views/post: mod/forum/amd/src/local/views/post

87
88 The following are all invalid module names and locations in your plugin:
89 mod_forum/views/post: mod/forum/amd/src/views/post
c5f3e924
SA
90* The 'xxxx_check_password_policy' method now has an extra parameter: $user. It contains the user object to perform password
91validation against and defaults to null (so, no user needed) if not provided.
0261d1ef
AN
92* It is now possible to use sub-directories when creating mustache templates.
93 The standard rules for Level 2 namespaces also apply to templates.
94 The sub-directory used must be either an valid component, or placed inside a 'local' directory to ensure that it does not conflict with other components.
95
96 The following are all valid template names and locations in your plugin:
97 mod_forum/forum_post: mod/forum/templates/forum_post.mustache
98 mod_forum/local/post/user: mod/forum/templates/local/post/user.mustache
99 mod_forum/form/checkbox_toggle: mod/forum/templates/form/checkbox_toggle.mustache

0261d1ef
AN
101 The following are _invalid_ template names and locations:
102 mod_forum/post/user: mod/forum/templates/local/post/user.mustache
09dedee2
MM
103* Following behat steps have been removed from core:
104 - I go to "<gradepath_string>" in the course gradebook
e2d97a46 105* A new admin setting widget 'core_admin\local\settings\filesize' is added.
1d6f041a 106* Core capabilities 'moodle/community:add' and 'moodle/community:download' have been removed from core as part of Moodle.net sunsetting.
14db7374
P
107* As part of Moodle.net sunsetting process the following hub api functions have been deprecated:
108 - get_courses
109 - unregister_courses
110 - register_course
111 - add_screenshot
112 - download_course_backup
113 - upload_course_backup
5beb3885
MN
114* A new setting 'Cache templates' was added (see MDL-66367). This setting determines if templates are cached or not.
115 This setting can be set via the UI or by defining $CFG->cachetemplates in your config.php file. It is a boolean
116 and should be set to either false or true. Developers will probably want to set this to false.
2d4ce64d 117* The core_enrol_edit_user_enrolment webservice has been deprecated. Please use core_enrol_submit_user_enrolment_form instead.
ca81e906 118* \single_button constructor has a new attributes param to add attributes to the button HTML tag.
60dc0242 119* Improved url matching behaviour for profiled urls and excluded urls

122* New H5P core subsystem have been added.
810d7a3d
SA
123* Introduced new callback for plugin developers '<component>_get_path_from_pluginfile($filearea, $args)': This will return
124the itemid and filepath for the filearea and path defined in $args. It has been added in order to get the correct itemid and
125filepath because some components, such as mod_page or mod_resource, add the revision to the URL where the itemid should be placed
126(to prevent caching problems), but then they don't store it in database.
225eb7b2 127* New utility function \core_form\util::form_download_complete should be called if your code sends
128 a file with Content-Disposition: Attachment in response to a Moodle form submit button (to ensure
129 that disabled submit buttons get re-enabled in that case). It is automatically called by the
130 filelib.php send_xx functions.
131* If you have a form which sends a file in response to a Moodle form submit button, but you cannot
132 call the above function because the file is sent by a third party library, then you should add
133 the attribute data-double-submit-protection="off" to your form.
7aeeb444 134
b91ddd16 135=== 3.7 ===
21406f66 136
9df03b19 137* Nodes in the navigation api can have labels for each group. See set/get_collectionlabel().
b91ddd16 138* The method core_user::is_real_user() now returns false for userid = 0 parameter
cabdadf3
SA
139* 'mform1' dependencies (in themes, js...) will stop working because a randomly generated string has been added to the id
140attribute on forms to avoid collisions in forms loaded in AJAX requests.
b51b6969
AN
141* A new method to allow queueing or rescheduling of an existing scheduled task was added. This allows an existing task
142 to be updated or queued as required. This new functionality can be found in \core\task\manager::reschedule_or_queue_adhoc_task.
ef96eb02 143* 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 144* 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
145* The \core_rating provider's get_sql_join function now accepts an optional $innerjoin parameter.
146 It is recommended that privacy providers using this function call rewrite any long query into a number of separate
147 calls to add_from_sql for improved performance, and that the new argument is used.
148 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
149* /message/defaultoutputs.php file and admin_page_defaultmessageoutputs class have been deprecated
150 and all their settings moved to admin/message.php (see MDL-64495). Please use admin_page_managemessageoutputs class instead.
545e2abb
SL
151* A new parameter $lang has been added to mustache_template_source_loader->load_with_dependencies() method
152 so it is possible for Mustache to request string in a specific language.
05a5d547 153* Behat timeout constants behat_base::TIMEOUT, EXTENDED_TIMEOUT, and REDUCED_TIMEOUT have been
154 deprecated. Please instead use the functions behat_base::get_timeout(), get_extended_timeout(),
155 and get_reduced_timeout(). These allow for timeouts to be increased by a setting in config.php.
e0695f87
JL
156* The $draftitemid parameter of file_save_draft_area_files() function now supports the constant IGNORE_FILE_MERGE:
157 When the parameter is set to that constant, the function won't process file merging, keeping the original state of the file area.
418a86c6 158 Notice also than when $text is set, pluginfile rewrite won't be processed so the text will not be modified.
5ba12283
JL
159* Introduced new callback for plugin developers '<component>_pre_processor_message_send($procname, $proceventdata)':
160 This will allow any plugin to manipulate messages or notifications before they are sent by a processor (email, mobile...)
f7b52799 161* New capability 'moodle/category:viewcourselist' in category context that controls whether user is able to browse list of courses
beff3806
MG
162 in this category. To work with list of courses use API methods in core_course_category and also 'course' form element.
163* It is possible to pass additional conditions to get_courses_search();
164 core_course_category::search_courses() now allows to search only among courses with completion enabled.
bf9f2555 165* Add support for a new xxx_after_require_login callback
734b198f
SA
166* A new conversation type has been created for self-conversations. During the upgrading process:
167 - Firstly, the existing self-conversations will be starred and migrated to the new type, removing the duplicated members in the
168 message_conversation_members table.
169 - Secondly, the legacy self conversations will be migrated from the legacy 'message_read' table. They will be created using the
170 new conversation type and will be favourited.
171 - Finally, the self-conversations for all remaining users without them will be created and starred.
172Besides, from now, a self-conversation will be created and starred by default to all the new users (even when $CFG->messaging
173is disabled).
b858b161
JP
174* New optional parameter $throwexception for \get_complete_user_data(). If true, an exception will be thrown when there's no
175 matching record found or when there are multiple records found for the given field value. If false, it will simply return false.
176 Defaults to false when not set.
cb28132d 177* Exposed submit button to allow custom styling (via customclassoverride variable) which can override btn-primary/btn-secondary classes
26e778d1
JL
178* `$includetoken` parameter type has been changed. Now supports:
179 boolean: False indicates to not include the token, true indicates to generate a token for the current user ($USER).
180 integer: Indicates to generate a token for the user whose id is the integer value.
181* The following functions have been updated to support the new usage:
182 - make_pluginfile_url
183 - file_rewrite_pluginfile_urls
e240a000 184* New mform element 'float' handles localised floating point numbers.
b91ddd16 185
437ffc9f 186=== 3.6 ===
187
883f6555
AN
188* A new token-based version of pluginfile.php has been added which can be used for out-of-session file serving by
189 setting the `$includetoken` parameter to true on the `moodle_url::make_pluginfile_url()`, and
190 `moodle_url::make_file_url()` functions.
191* The following picture functions have been updated to support use of the new token-based file serving:
192 - print_group_picture
193 - get_group_picture_url
88d89512
AN
194* The `user_picture` class has a new public `$includetoken` property which can be set to make use of the new token-based
195 file serving.
9411beb3 196* Custom AJAX handlers for the form autocomplete fields can now optionally return string in their processResults()
2dd33840 197 callback. If a string is returned, it is displayed instead of the list of suggested items. This can be used, for
9411beb3 198 example, to inform the user that there are too many items matching the current search criteria.
f8d15c66 199* The form element 'htmleditor' has been deprecated. Please use the 'editor' element instead.
350d7b06 200* The print_textarea() function has been deprecated. Please use $OUTPUT->print_textarea() instead.

253 - I navigate to "PATH > ITEM" in site administration
254 - I navigate to course participants
255 - I navigate to "TAB1 > TAB2" in the course gradebook
02fda279
VDF
256 If some items are not available without Navigation block at all, one can use combination of:
257 - I add the "Navigation" block if not present
258 - I click on "LINK" "link" in the "Navigation" "block"
4f06a977
EL
259* The core\session\util class has been removed. This contained one function only used by the memcached class which has

afa3e0ff
DM
271* The user_selector classes do not support custom list of extra identity fields any more. They obey the configured user
272 policy and respect the privacy setting made by site administrators. The list of user identifiers should never be
273 hard-coded. Instead, the setting $CFG->showuseridentity should be always respected, which has always been the default
274 behaviour (MDL-59847).
cc4952e9
AG
275* The function message_send() in messagelib.php will now only take the object \core\message\message as a parameter.

69781cda
JP
289* \core_user_external::create_users() and \core_user_external::update_users() can now accept more user profile fields so user
290 creation/update via web service can now be very similar to the edit profile page's functionality. The new fields that have been
291 added are:

312the groupid field.
1afbb97b
AO
313* Added $CFG->conversionattemptlimit setting to config.php allowing a maximum number of retries before giving up conversion
314 of a given document by the assignfeedback_editpdf\task\convert_submissions task. Default value: 3.
beeadbf7
MN
315* The following events have been deprecated and should not be used any more:
316 - message_contact_blocked
317 - message_contact_unblocked
318 The reason for this is because you can now block/unblock users without them necessarily being a contact. These events
319 have been replaced with message_user_blocked and message_user_unblocked respectively.

320* The event message_deleted has been changed, it no longer records the value of the 'useridto' due to
321 the introduction of group messaging. Please, if you have any observers or are triggering this event
322 in your code you will have to make some changes!

323* The gradebook now supports the ability to accept files as feedback. This can be achieved by adding
324 'feedbackfiles' to the $grades parameter passed to grade_update().
325 For example -
326 $grades['feedbackfiles'] = [
327 'contextid' => 1,
328 'component' => 'mod_xyz',
329 'filearea' => 'mod_xyz_feedback',
330 'itemid' => 2
331 ];
332 These files will be then copied to the gradebook file area.

333* Allow users to choose who can message them for privacy reasons, with a 'growing circle of contactability':
334 - Added $CFG->messagingallusers, for enabling messaging to all site users. Default value: 0.
335 When $CFG->messagingallusers = false users can choose being contacted by only contacts or contacts and users sharing a course with them.
336 In that case, the default user preference is MESSAGE_PRIVACY_COURSEMEMBER (users sharing a course).
337 When $CFG->messagingallusers = true users have a new option for the privacy messaging preferences: "Anyone on the site". In that case,
338 the default user preference is MESSAGE_PRIVACY_SITE (all site users).
339 - Added $CFG->keepmessagingallusersenabled setting to config.php to force enabling $CFG->messagingallusers during the upgrading process.
340 Default value: 0.
341 When $CFG->keepmessagingallusersenabled is set to true, $CFG->messagingallusers will be also set to true to enable messaging site users.
342 However, when it is empty, $CFG->messagingallusers will be disabled during the upgrading process, so the users will only be able to
343 message contacts and users sharing a course with them.

344* There has been interface and functional changes to admin_apply_default_settings() (/lib/adminlib.php). The function now takes two
345 additional optional parameters, $admindefaultsettings and $settingsoutput. It also has a return value $settingsoutput.
346 The function now does not need to be called twice to ensure all default settings are set. Instead the function calls itself recursively
347 until all settings have been set. The additional parameters are used recursively and shouldn't be need to be explicitly passed in when calling
348 the function from other parts of Moodle.
349 The return value: $settingsoutput is an array of setting names and the values that were set by the function.
160e77f9 350* Webservices no longer update the lastaccess time for a user in a course. Call core_course_view_course() manually if needed.
0616f045 351* 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.

407* The moodleform element classes can now optionally provide a public function validateSubmitValue(). This method can be
408 used to perform implicit validation of submitted values - without the need to explicitly add the validation rules to
409 every form. The method should accept a single parameter with the submitted value. It should return a string with the
410 eventual validation error, or an empty value if the validation passes.

412* Enrol plugins which provide enrolment actions can now declare the following "data-action" attributes in their implementation of
413 enrol_plugin::get_user_enrolment_actions() whenever applicable:
414 * "editenrolment" - For editing a user'e enrolment details. Defined by constant ENROL_ACTION_EDIT.
415 * "unenrol" - For unenrolling a student. Defined by constant ENROL_ACTION_UNENROL.
416 These attributes enable enrol actions to be rendered via modals. If not added, clicking on the enrolment action buttons will still
417 redirect the user to the appropriate enrolment action page. Though optional, it is recommended to add these attributes for a
418 better user experience when performing enrol actions.

419* The enrol_plugin::get_user_enrolment_actions() implementations for core enrol plugins have been removed and moved to
420 the parent method itself. New enrol plugins don't have to implement get_user_enrolment_actions(), but just need to
421 make sure that they override:
422 - enrol_plugin::allow_manage(), and/or
423 - enrol_plugin::allow_unenrol_user() or enrol_plugin::allow_unenrol()
424 Existing enrol plugins that override enrol_plugin::get_user_enrolment_actions() don't have to do anything, but can
425 also opt to remove their own implementation of the method if they basically have the same logic as the parent method.

469* Moodle has support for font-awesome icons. Plugins should use the xxx_get_fontawesome_icon_map callback
470 to map their custom icons to one from font-awesome.
471* $OUTPUT->pix_url() has been deprecated because it is was used mostly to manually generate image tags for icons.
472 We now distinguish between icons and "small images". The difference is that an icon does not have to be rendered as an image tag
473 with a source. It is OK to still have "small images" - if this desired use $OUTPUT->image_icon() and $OUTPUT->image_url(). For
474 other uses - use $OUTPUT->pix_icon() or the pix helper in mustache templates {{#pix}}...{{/pix}}
c266d256 475 For other valid use cases use $OUTPUT->image_url().

638* PostgreSQL connections now use advanced options to reduce connection overhead. These options are not compatible
639 with some connection poolers. The dbhandlesoptions parameter has been added to allow the database to configure the
640 required defaults. The parameters that are required in the database are;
641 ALTER DATABASE moodle SET client_encoding = UTF8;
642 ALTER DATABASE moodle SET standard_conforming_strings = on;
ce7863ba 643 ALTER DATABASE moodle SET search_path = 'moodle,public'; -- Optional, if you wish to use a custom schema.
f834a8f5 644 You can set these options against the database or the moodle user who connects.

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

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

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

656* The minifier library used by core_minify has been switched to https://github.com/matthiasmullie/minify - there are minor differences
657 in minifier output.

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

661* The first parameter $eventdata of both message_send() and \core\message\manager::send_message() should
662 be \core\message\message. Use of stdClass is deprecated.
663* The message_sent event now expects other[courseid] to be always set, exception otherwise. For BC with contrib code,
664 message_sent::create_from_ids() will show a debugging notice if the \core\message\message being sent is missing
665 the courseid property, defaulting to SITEID automatically. In Moodle 3.6 (MDL-55449) courseid will be fully mandatory
666 for all messages sent.
d6a25bc4 667* The send_confirmation_email() function has a new optional parameter $confirmationurl to provide a different confirmation URL.
bb316e07
JD
668* Introduced a new hook for plugin developers:
669 - <component>_course_module_background_deletion_recommended()
670 This hook should be used in conjunction with the existing '<component>_pre_course_module_delete($mod)'. It must
671 return a boolean and is called by core to check whether a plugin's implementation of
672 <component>_pre_course_module_deleted($mod) will take a long time. A plugin should therefore only implement this
673 function if it also implements <component>_pre_course_module_delete($mod).
674 An example in current use is recyclebin, which performs what can be a lengthy backup process in
675 tool_recyclebin_pre_course_module_delete. The recyclebin, if enabled, now returns true in its implementation of
676 tool_recyclebin_course_module_background_deletion_recommended(), to indicate to core that the deletion (and
677 execution of tool_recyclebin_pre_course_module_delete) should be handled with an adhoc task, meaning it will not
678 occur in real time.

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

756 * Class moodleform, moodleform_mod and some module classes have been changed to use
757 __construct() for the constructor. Calling parent constructors by the class
758 name will display debugging message. Incorrect: parent::moodleform(),
759 correct: parent::__construct()
760 * All form elements have also changed the constructor syntax. No changes are
761 needed for using form elements, however if plugin defines new form element it
762 needs to use correct syntax. For example, incorrect: parent::HTML_QuickForm_input(),
763 HTML_QuickForm_input::HTML_QuickForm_input(), $this->HTML_QuickForm_input().
764 Correct: HTML_QuickForm_input::__construct() or parent::__construct().

804 - <component>_pre_block_delete($instance)
805 - <component>_pre_user_delete($user)
b858b161 806 These hooks allow developers to use the item in question before it is deleted by core. For example, if your plugin is
a9ad3002
MN
807 a module (plugins located in the mod folder) called 'xxx' and you wish to interact with the user object before it is
808 deleted then the function to create would be mod_xxx_pre_user_delete($user) in mod/xxx/lib.php.

982* For 3rd party plugin specific environment.xml files, it's now possible to specify version independent checks by using the
983 <PLUGIN name="component_name"> tag instead of the version dependent <MOODLE version="x.y"> one. If the PLUGIN tag is used any
984 Moodle specific tags will be ignored.

990* $CFG->enabletgzbackups setting has been removed as now backups are stored internally using .tar.gz format by default, you can
991 set $CFG->usezipbackups to store them in zip format. This does not affect the restore process, which continues accepting both.
9bcb0ba8

992* Added support for custom string manager implementations via $CFG->customstringmanager
993 directive in the config.php. See MDL-49361 for details.
70be2642 994* Add new make_request_directory() for creation of per-request files.
b7067f06

1013* Gradebook grade category option "aggregatesubcats" has been removed completely.
1014 This means that the database column is removed, the admin settings are removed and
1015 the properties from the grade_category object have been removed. If any courses were
1016 found to be using this setting, a warning to check the grades will be shown in the
1017 course grader report after upgrading the site. The same warning will be shown on
1018 courses restored from backup that had this setting enabled (see MDL-47503).

1020* renderers: We now remove the suffix _renderable when looking for a render method for a renderable.
1021 If you have a renderable class named like "blah_renderable" and have a method on a renderer named "render_blah_renderable"
1022 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 1023* New functions get_course_and_cm_from_cmid($cmorid, $modulename) and
1024 get_course_and_cm_from_instance($instanceorid, $modulename) can be used to
1025 more efficiently load these basic data objects at the start of a script.
1026* New function cm_info::create($cm) can be used when you need a cm_info
1027 object, but have a $cm which might only be a standard database record.
061e6b28 1028* $CFG->enablegroupmembersonly no longer exists.
16078807
DP
1029* Scheduled tasks have gained support for syntax to introduce variability when a

1070 hashing.
1071* user_update_user() and user_create_user() api's accept optional param

8d1f33e1 1121* Conditional availability API has moved and changed. The condition_info class is
1122 replaced by \core_availability\info_module, and condition_info_section by
1123 \core_availability\info_section. (Code that uses the old classes will generally
1124 still work.)
1125* coursemodule_visible_for_user() has been deprecated but still works - replaced
1126 by a new static function \core_availability\info_module::is_user_visible()
1127* cm_info::is_user_access_restricted_by_conditional_access has been deprecated
1128 but still works (it has never done what its name suggests, and is
1129 unnecessary).
1130* cm_info and section_info property showavailability has been deprecated, but
1131 still works (with the caveat that this information is now per-user).

1143 condition plugins in /availability/condition. The new API is very similar with
1144 regard to checking availability, but any code that modifies availability settings
1145 for an activity or section is likely to need substantial changes.

1172 get_plugin_list(), get_plugin_list_with_class(), get_plugin_directory(), normalize_component(),
1173 get_component_directory() and get_plugin_list_with_file(). The names of the new methods are
1174 exactly the same, the only differences are that core_component::get_plugin_types() now always returns
1175 full paths and core_component::get_plugin_list() does not accept empty parameter any more.
d534708f 1176* Use core_text::* instead of textlib:: and also core_collator::* instead of collatorlib::*.
af578aec 1177* Use new function moodleform::mock_submit() to simulate form submission in unit tests (backported).
85b38061 1178* New $CFG->localcachedir setting useful for cluster nodes. Admins have to update X-Sendfile aliases if used.

PS
1179* MS SQL Server drivers are now using NVARCHAR(MAX) instead of NTEXT and VARBINARY(MAX) instead of IMAGE,
1180 this change should be fully transparent and it should help significantly with add-on compatibility.

ac2b2713 1189* Subplugins are supported in admin tools and local plugins.
71ab7e51 1190* file_packer/zip_packer API has been modified so that key functions support a new file_progress interface
1191 to report progress during long operations. Related to this, zip_archive now supports an estimated_count()
1192 function that returns an approximate number of entries in the zip faster than the count() function.
d872881f 1193* Class cm_info no longer extends stdClass. All properties are read-only and calculated on first request only.
44ddd2a1 1194* Class course_modinfo no longer extends stdClass. All properties are read-only.
64501eee
MG
1195* Database fields modinfo and sectioncache in table course are removed. Application cache core/coursemodinfo
1196 is used instead. Course cache is still reset, rebuilt and retrieved using function rebuild_course_cache() and
1197 get_fast_modinfo(). Purging all caches and every core upgrade purges course modinfo cache as well.
1198 If function get_fast_modinfo() is called for multiple courses make sure to include field cacherev in course
1199 object.

5fed8433 1208* $USER->password field is intentionally unset so that session data does not contain password hashes.
38fc0130 1209* Use core_shutdown_manager::register_function() instead of register_shutdown_function().
c858655d 1210* New file packer for .tar.gz files; obtain by calling get_file_packer('application/x-gzip'). Intended initially
1211 for use in backup/restore only, as there are limitations on supported filenames. Also new packer for
1212 backups which supports both compression formats; get_file_packer('application/vnd.moodle.backup').
1213* New optional parameter to stored_file::get_content_file_handle to open file handle with 'gzopen' instead
1214 of 'fopen' to read gzip-compressed files if required.
6c679d15 1215* update_internal_user_password() and setnew_password_and_mail() now trigger user_updated event.

2dd8e935
DP
1217* New class introduced to help auto generate zIndex values for modal dialogues. Class "moodle-has-zindex"
1218 should set on any element which uses a non-default zindex and needs to ensure it doesn't show above a
1219 dialogue.
0c431257

1371* The database drivers (moodle_database and subclasses) aren't using anymore the ::columns property
1372 for caching database metadata. MUC (databasemeta) is used instead. Any custom DB driver should
1373 apply for that change.

1374* The cron output has been changed to include time and memory usage (see cron_trace_time_and_memory()),
1375 so any custom utility relying on the old output may require modification.

DW
1376* Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
1377 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
1378 an option for 0 bytes. Existing code that was replacing the 0 option in the return
1379 from this function with a more sensible message, can now use the return from this function directly.

1387* The function delete_course_module was deprecated and has been replaced with
1388 course_delete_module. The reason for this was because the function delete_course_module
1389 only partially deletes data, so wherever it was called extra code was needed to
1390 perform the whole deletion process. The function course_delete_module now takes care
1391 of the whole process.

1392* curl::setopt() does not accept constant values any more. As it never worked properly,
1393 we decided to make the type check stricter. Now, the keys of the array pass must be a string
1394 corresponding to the curl constant name.

1395* Function get_users_listing now return list of users except guest and deleted users. Previously
1396 deleted users were excluded by get_users_listing. As guest user is not expected while browsing users,
1397 and not included in get_user function, it will not be returned by get_users_listing.

1400* The signature of the add() method of classes implementing the parentable_part_of_admin_tree
1401 interface (such as admin_category) has been extended. The new parameter allows the caller
1402 to prepend the new node before an existing sibling in the admin tree.

1420* Additional (optional) param $onlyactive has been added to get_enrolled_users, count_enrolled_users
1421 functions to get information for only active (excluding suspended enrolments) users. Included two
1422 helper functions extract_suspended_users, get_suspended_userids to extract suspended user information.
e87214bd 1423* The core_plugin_manager class now provides two new helper methods for getting information
d7d48b40 1424 about known plugins: get_plugins_of_type() and get_subplugins_of_plugin().
e87214bd 1425* The get_uninstall_url() method of all subclasses of \core\plugininfo\base class is now expected
73658371
DM
1426 to always return moodle_url. Subclasses can use the new method is_uninstall_allowed()
1427 to control the availability of the 'Uninstall' link at the Plugins overview page (previously
1428 they would do it by get_uninstall_url() returning null). By default, URL to a new general plugin
1429 uninstall tool is returned. Unless the plugin type needs extra steps that can't be handled by
1430 plugininfo_xxx::uninstall() method or xmldb_xxx_uninstall() function, this default URL should
1431 satisfy all plugin types.
