15* Webservice function core_course_search_courses accepts a new parameter 'limittoenrolled' to filter the results
16 only to courses the user is enrolled in, and are visible to them.
56fa860e
DW
17* External functions that are not calling external_api::validate_context are buggy and will now generate
18 exceptions. Previously they were only generating warnings in the webserver error log.
e02e7f5a 19 See https://docs.moodle.org/dev/External_functions_API#Security
221bfffd 20* The moodle/blog:associatecourse and moodle/blog:associatemodule capabilities has been removed.

34* The google api library has been updated to version 1.1.7. There was some important changes
35 on the SSL handling. Now the SSL version will be determined by the underlying library.
36 For more information see https://github.com/google/google-api-php-client/pull/644
b6d12864
AE
37* The get_role_users() function will now add the $sort fields that are not part
38 of the requested fields to the query result and will throw a debugging message
39 with the added fields when that happens.
dccf9ca3
SL
40* The core_user::fill_properties_cache() static method has been introduced to be a reference
41 and allow standard user fields data validation. Right now only type validation is supported
42 checking it against the parameter (PARAM_*) type of the target user field. MDL-52781 is
43 going to add support to null/not null and choices validation, replacing the existing code to
44 validate the user fields in different places in a common way.
235ef57a
DW
45* Webservice function core_course_search_courses now returns results when the search string
46 is less than 2 chars long.
47* Webservice function core_course_search_courses accepts a new parameter 'requiredcapabilities' to filter the results
48 by the capabilities of the current user.
49* New mform element 'course' handles thousands of courses with good performance and usability.
3ad96419
AN
50* The redirect() function will now redirect immediately if output has not
51 already started. Messages will be displayed on the subsequent page using
52 session notifications. The type of message output can be configured using the
53 fourth parameter to redirect().
24346803
AN
54* The specification of extra classes in the $OUTPUT->notification()
55 function, and \core\output\notification renderable have been deprecated
56 and will be removed in a future version.
57 Notifications should use the levels found in \core\output\notification.
58* The constants for NOTIFY_PROBLEM, NOTIFY_REDIRECT, and NOTIFY_MESSAGE in
59 \core\output\notification have been deprecated in favour of NOTIFY_ERROR,
60 NOTIFY_WARNING, and NOTIFY_INFO respectively.
1405f010
EL
61* The following functions, previously used (exclusively) by upgrade steps are not available
62 anymore because of the upgrade cleanup performed for this version. See MDL-51580 for more info:
63 - upgrade_mysql_fix_unsigned_and_lob_columns()
64 - upgrade_course_completion_remove_duplicates()
65 - upgrade_save_orphaned_questions()
66 - upgrade_rename_old_backup_files_using_shortname()

DW
73* A new parameter $ajaxformdata was added to the constructor for moodleform. When building a
74 moodleform in a webservice or ajax script (for example using the new fragments API) we
75 cannot allow the moodleform to parse it's own data from _GET and _POST - we must pass it as
76 an array.
20dde5e6
JPG
77* Plugins can extend the navigation for user by declaring the following callback:
78 <frankenstyle>_extend_navigation_user(navigation_node $parentnode, stdClass $user,
79 context_user $context, stdClass $course,
80 context_course $coursecontext)
c917b53a 81* The function notify() now throws a debugging message - see MDL-50269.
53907dbe
DP
82* Ajax calls going through lib/ajax/* now validate the return values before sending
83 the response. If the validation does not pass an exception is raised. This behaviour
84 is consistent with web services.
1a0df553
MG
85* Several changes in Moodle core, standard plugins and third party libraries to
86 ensure compatibility with PHP7. All plugins are recommended to perform testing
479950d4
MG
87 against PHP7 as well. Refer to https://docs.moodle.org/dev/Moodle_and_PHP7 for more
88 information. The following changes may affect you:
1a0df553
MG
89 * Class moodleform, moodleform_mod and some module classes have been changed to use
90 __construct() for the constructor. Calling parent constructors by the class
91 name will display debugging message. Incorrect: parent::moodleform(),
92 correct: parent::__construct()
93 * All form elements have also changed the constructor syntax. No changes are
94 needed for using form elements, however if plugin defines new form element it
95 needs to use correct syntax. For example, incorrect: parent::HTML_QuickForm_input(),
96 HTML_QuickForm_input::HTML_QuickForm_input(), $this->HTML_QuickForm_input().
97 Correct: HTML_QuickForm_input::__construct() or parent::__construct().
c4d0b752
MG
98 * profile_field_base::profile_field_base() is deprecated, use parent::__construct()
99 in custom profile fields constructors. Similar deprecations in exsiting
100 profile_field_* classes.
101 * user_filter_type::user_filter_type() is deprecated, use parent::__construct() in
102 custom user filters. Similar deprecations in existing user_filter_* classes.
103 * table_default_export_format_parent::table_default_export_format_parent() is
104 deprecated, use parent::__construct() in extending classes.
c026a28d
MG
105* groups_delete_group_members() $showfeedback parameter has been removed and is no longer
106 respected. Users of this function should output their own feedback if required.
107* Number of changes to Tags API, see tag/upgrade.txt for more details
32f8bbd8
DM
108* The previous events API handlers are being deprecated in favour of events 2 API, debugging messages are being displayed if
109 there are 3rd party plugins using it. Switch to events 2 API please, see https://docs.moodle.org/dev/Event_2#Event_dispatching_and_observers
110 Note than you will need to bump the plugin version so moodle is aware that you removed the plugin's event handlers.
2edb12ec
DM
111* mforms validation functions are not available in the global JS namespace anymore, event listeners
112 are assigned to fields and buttons through a self-contained JS function.
2ab797c9
BH
113* Added $CFG->urlrewriteclass option to config.php allowing clean / semantic urls to
114 be implemented in a plugin, eg local_cleanurls.
11362ae3
RK
115* $CFG->pathtoclam global setting has been moved to clamav antivirus plugin setting of the same name.
116* clam_message_admins() and get_clam_error_code() have been deprecated, its functionality
117 is now a part of \antivirus_clamav\scanner class methods.
118* \repository::antivir_scan_file() has been deprecated, \core\antivirus\manager::scan_file() that
375223c6 119 applies antivirus plugins is replacing its functionality.
d84a657d 120* Added core_text::str_max_bytes() which safely truncates multi-byte strings to a maximum number of bytes.
b5e6ec44 121* Zend Framework has been removed completely.
322f3141 122* Any plugin can report when a scale is being used with the callback function [pluginname]_scale_used_anywhere(int $scaleid).
529ea77b 123* Changes in file_rewrite_pluginfile_urls: Passing a new option reverse = true in the $options var will make the function to convert
296ab1e2 124 actual URLs in $text to encoded URLs in the @@PLUGINFILE@@ form.
e891c838 125* behat_util::is_server_running() is removed, please use behat_util::check_server_status() instead.
921faad9
RT
126* Behat\Mink\Selector\SelectorsHandler::xpathLiteral() method is deprecated use behat_context_helper::escape instead
127 when building Xpath, or pass the unescaped value when using the named selector.',
9df4ae41 128* table_sql download process is using the new data formats plugin which you can't use if you are buffering any output
a2e6df5e
EL
129 * flexible_table::get_download_menu(), considered private, has been deleted. Use
130 $OUTPUT->download_dataformat_selector() instead.
bc219382
MS
131 when building Xpath, or pass the unescaped value when using the named selector.
132* Add new file_is_executable(), to consistently check for executables even in Windows (PHP bug #41062).
3fb5ddc3 133* Introduced new hooks for plugin developers.
a9ad3002
MN
134 - <component>_pre_course_category_delete($category)
135 - <component>_pre_course_delete($course)
136 - <component>_pre_course_module_delete($cm)
137 - <component>_pre_block_delete($instance)
138 - <component>_pre_user_delete($user)
139 These hooks allow developers to use the item in question before it is deleted by core. For example, if your plugin is
140 a module (plugins located in the mod folder) called 'xxx' and you wish to interact with the user object before it is
141 deleted then the function to create would be mod_xxx_pre_user_delete($user) in mod/xxx/lib.php.

98ea6973
DM
153* All plugins are required to declare their frankenstyle component name via

303936aa 160* \core\progress\null is renamed to \core\progress\none for improved PHP7 compatibility as null is a reserved word (see MDL-50453).
cd27a860
AN
161* \webservice_xmlrpc_client now respects proxy server settings. If your XMLRPC server is available on your local network and not via your proxy server, you may need to add it to the list of proxy

eee9e47d 280* The never unused webdav_locks table was dropped.
ccfb9b69
NM
281* The actionmenu hideMenu() function now expects an EventFacade object to be passed to it,
282 i.e. a call to M.core.actionmenu.instance.hideMenu() should be change to M.core.actionmenu.instance.hideMenu(e)
40a15455 283* In the html_editors (tinyMCE, Atto), the manage files button can be hidden by changing the 'enable_filemanagement' option to false.

290 line interface scripts.
9748791b
JL
291* External function core_course_external::get_course_contents returned parameter "name" has been changed to PARAM_RAW,
292 this is because the new external_format_string function may return raw data if the global moodlewssettingraw parameter is used.
182d9990 293* Function is_web_crawler() has been deprecated, please use core_useragent::is_web_crawler() instead.
303936aa 294
ebea19cb
FM

310 the message in the sink instead.
c9bd4e41 311* The file pluginlib.php was deprecated since 2.6 and has now been removed, do not include or require it.
9802bd61 312* \core_component::fetch_subsystems() now returns a valid path for completion component instead of null.
7d0d3b36 313* Deprecated JS global methods have been removed (show_item, destroy_item, hide_item, addonload, getElementsByTagName, findChildNodes).
8072628a
NM
314* For 3rd party plugin specific environment.xml files, it's now possible to specify version independent checks by using the
315 <PLUGIN name="component_name"> tag instead of the version dependent <MOODLE version="x.y"> one. If the PLUGIN tag is used any
316 Moodle specific tags will be ignored.
3451a51c 317* 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).
8d9bdd28

319 now relies on the main config.php when deploying an available update.
45a1a16b 320* sql_internal_reader and sql_select_reader interfaces have been deprecated in favour of sql_internal_table_reader
9fe26fb8 321 and sql_reader which use iterators to be more memory efficient.
79565fa5
DM
322* $CFG->enabletgzbackups setting has been removed as now backups are stored internally using .tar.gz format by default, you can
323 set $CFG->usezipbackups to store them in zip format. This does not affect the restore process, which continues accepting both.
9bcb0ba8
DM
324* Added support for custom string manager implementations via $CFG->customstringmanager
325 directive in the config.php. See MDL-49361 for details.
70be2642 326* Add new make_request_directory() for creation of per-request files.
b7067f06
AN
327* Added generate_image_thumbnail_from_string. This should be used instead of generate_image_thumbnail when the source is a string.
328 This prevents the need to write files to disk unnecessarily.
329* Added generate_image_thumbnail to stored_file class. This should be used when generating thumbnails for stored files.
330 This prevents the need to write files to disk unnecessarily.
3004a923 331* Removed pear/HTTP/WebDav. See MDL-49534 for details.
d6e7a63d 332* Use standard PHP date time classes and methods - see new core_date class for timezone normalisation methods.
aec4292c
DC
333* Moved lib/google/Google/ to lib/google/src/Google. This is to address autoloader issues with Google's provided autoloader
334 for the library. See MDL-49519 for details.
2b90ce65
EL
335* The outdated lib/google/Google_Client.php and related files have been completely removed. To use
336 the new client, read lib/google/readme_moodle.txt, please.
b19cc4ef 337* profile_display_badges() has been deprecated. See MDL-48935 for details.
12261113
AG
338* Added a new method add_report_nodes() to pagelib.php. If you are looking to add links to the user profile page under the heading "Reports"
339 then please use this function to ensure that the breadcrumb and navigation block are created properly for all user profile pages.
cda2a827
FM
340* process_new_icon() now does not always return a PNG file. When possible, it will try to keep the format of the original file.
341 Set the new argument $preferpng to true to force PNG. See MDL-46763 and MDL-50041 for details.

47d6e6a7
DW
345* Gradebook grade category option "aggregatesubcats" has been removed completely.
346 This means that the database column is removed, the admin settings are removed and
347 the properties from the grade_category object have been removed. If any courses were
348 found to be using this setting, a warning to check the grades will be shown in the
349 course grader report after upgrading the site. The same warning will be shown on
350 courses restored from backup that had this setting enabled (see MDL-47503).
4051685b 351* lib/excelllib.class.php has been updated. The class MoodleExcelWorkbook will now only produce excel 2007 files.
ebdcb292

352* renderers: We now remove the suffix _renderable when looking for a render method for a renderable.
353 If you have a renderable class named like "blah_renderable" and have a method on a renderer named "render_blah_renderable"
354 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 355* New functions get_course_and_cm_from_cmid($cmorid, $modulename) and
356 get_course_and_cm_from_instance($instanceorid, $modulename) can be used to
357 more efficiently load these basic data objects at the start of a script.
358* New function cm_info::create($cm) can be used when you need a cm_info
359 object, but have a $cm which might only be a standard database record.
061e6b28 360* $CFG->enablegroupmembersonly no longer exists.

8d1f33e1 453* Conditional availability API has moved and changed. The condition_info class is
454 replaced by \core_availability\info_module, and condition_info_section by
455 \core_availability\info_section. (Code that uses the old classes will generally
456 still work.)
457* coursemodule_visible_for_user() has been deprecated but still works - replaced
458 by a new static function \core_availability\info_module::is_user_visible()
459* cm_info::is_user_access_restricted_by_conditional_access has been deprecated
460 but still works (it has never done what its name suggests, and is
461 unnecessary).
462* cm_info and section_info property showavailability has been deprecated, but
463 still works (with the caveat that this information is now per-user).
464* cm_info and section_info properties availablefrom and availableuntil have been
465 deprecated and always return zero (underlying data doesn't have these values).
466* section_info property groupingid has been deprecated and always returns zero,
467 same deal.

468* Various cm_info methods have been deprecated in favour of their read-only properties (get_url(), get_content(), get_extra_classes(),
469 get_on_click(), get_custom_data(), get_after_link, get_after_edit_icons)
af64bc61 470* The ajaxenabled function has been deprecated and always returns true. All code should be fully functional in Javascript.

c4b0d6dc 472
8d1f33e1 473Conditional availability (activities and sections):
474* New conditional availability API in /availability, including new availability
475 condition plugins in /availability/condition. The new API is very similar with
476 regard to checking availability, but any code that modifies availability settings
477 for an activity or section is likely to need substantial changes.

d0cac8b5
FM
504 get_plugin_list(), get_plugin_list_with_class(), get_plugin_directory(), normalize_component(),
505 get_component_directory() and get_plugin_list_with_file(). The names of the new methods are
506 exactly the same, the only differences are that core_component::get_plugin_types() now always returns
507 full paths and core_component::get_plugin_list() does not accept empty parameter any more.
d534708f 508* Use core_text::* instead of textlib:: and also core_collator::* instead of collatorlib::*.
af578aec 509* Use new function moodleform::mock_submit() to simulate form submission in unit tests (backported).
85b38061 510* New $CFG->localcachedir setting useful for cluster nodes. Admins have to update X-Sendfile aliases if used.
656250de
PS
511* MS SQL Server drivers are now using NVARCHAR(MAX) instead of NTEXT and VARBINARY(MAX) instead of IMAGE,
512 this change should be fully transparent and it should help significantly with add-on compatibility.
598a82c9
PS
513* The string manager classes were renamed. Note that they should not be modified or used directly,
514 always use get_string_manager() to get instance of the string manager.
aae18d2a 515* The ability to use an 'insecure' rc4encrypt/rc4decrypt key has been removed.
96f81ea3
PS
516* Use $CFG->debugdeveloper instead of debugging('', DEBUG_DEVELOPER).
517* Use set_debugging(DEBUG_xxx) when changing debugging level for current request.
d55f05ef 518* Function moveto_module() does not modify $mod argument and instead now returns the new module visibility value.
db5f2d33

519* Use behat_selectors::get_allowed_text_selectors() and behat_selectors::get_allowed_selectors() instead of
520 behat_command::$allowedtextselectors and behat_command::$allowedselectors
ac2b2713 521* Subplugins are supported in admin tools and local plugins.
71ab7e51 522* file_packer/zip_packer API has been modified so that key functions support a new file_progress interface
523 to report progress during long operations. Related to this, zip_archive now supports an estimated_count()
524 function that returns an approximate number of entries in the zip faster than the count() function.
d872881f 525* Class cm_info no longer extends stdClass. All properties are read-only and calculated on first request only.
44ddd2a1 526* Class course_modinfo no longer extends stdClass. All properties are read-only.
64501eee
MG
527* Database fields modinfo and sectioncache in table course are removed. Application cache core/coursemodinfo
528 is used instead. Course cache is still reset, rebuilt and retrieved using function rebuild_course_cache() and
529 get_fast_modinfo(). Purging all caches and every core upgrade purges course modinfo cache as well.
530 If function get_fast_modinfo() is called for multiple courses make sure to include field cacherev in course
531 object.

RT
532* Internal (noreply and support) user support has been added for sending/receiving message.
533 Use core_user::get_noreply_user() and core_user::get_support_user() to get noreply and support user's respectively.
534 Real users can be used as noreply/support users by setting $CFG->noreplyuserid and $CFG->supportuserid
137885b7 535* New function readfile_allow_large() in filelib.php for use when very large files may need sending to user.
e87214bd 536* Use core_plugin_manager::reset_caches() when changing visibility of plugins.
bde002b8
PS
537* Implement new method get_enabled_plugins() method in subplugin info classes.
538* Each plugin should include version information in version.php.
723a6e56 539* Module and block tables do not contain version column any more, use get_config('xx_yy', 'version') instead.
5fed8433 540* $USER->password field is intentionally unset so that session data does not contain password hashes.
38fc0130 541* Use core_shutdown_manager::register_function() instead of register_shutdown_function().
c858655d 542* New file packer for .tar.gz files; obtain by calling get_file_packer('application/x-gzip'). Intended initially
543 for use in backup/restore only, as there are limitations on supported filenames. Also new packer for
544 backups which supports both compression formats; get_file_packer('application/vnd.moodle.backup').
545* New optional parameter to stored_file::get_content_file_handle to open file handle with 'gzopen' instead
546 of 'fopen' to read gzip-compressed files if required.
6c679d15 547* update_internal_user_password() and setnew_password_and_mail() now trigger user_updated event.
b2858b91 548* Add thirdpartylibs.xml file to plugins that bundle any 3rd party libraries.
2dd8e935
DP
549* New class introduced to help auto generate zIndex values for modal dialogues. Class "moodle-has-zindex"
550 should set on any element which uses a non-default zindex and needs to ensure it doesn't show above a
551 dialogue.
0c431257
PS
552* $CFG->filelifetime is now used consistently for most file serving operations, the default was lowered
553 to 6 hours from 24 hours because etags and x-sendfile support should make file serving less expensive.

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

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

559* Settings pages are now possible for Calendar type plugins. Calendar type plugins that require a settings page to
560 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.

689 be captured using handlers, but they should not be used any more.
690 * groups_members_removed -> \core\event\group_member_removed
691 * groups_groupings_groups_removed -> (no replacement)
692 * groups_groups_deleted -> \core\event\group_deleted

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

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

708* Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
709 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
710 an option for 0 bytes. Existing code that was replacing the 0 option in the return
711 from this function with a more sensible message, can now use the return from this function directly.
9a36be73 712* Functions responsible for output in course/lib.php are deprecated, the code is moved to

718 problematic files when creating archive

719* The function delete_course_module was deprecated and has been replaced with
720 course_delete_module. The reason for this was because the function delete_course_module
721 only partially deletes data, so wherever it was called extra code was needed to
722 perform the whole deletion process. The function course_delete_module now takes care
723 of the whole process.

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

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

730* The add_* functions in course/dnduploadlib.php have been deprecated. Plugins should be using the
731 MODNAME_dndupload_register callback instead.
690a55f6
DM
732* The signature of the add() method of classes implementing the parentable_part_of_admin_tree
733 interface (such as admin_category) has been extended. The new parameter allows the caller
734 to prepend the new node before an existing sibling in the admin tree.
87b6981e
EL
735* condition_info:get_condition_user_fields($formatoptions) now accepts the optional
736 param $formatoptions, that will determine if the field names are processed by
737 format_string() with the passed options.
689096bc 738* remove all references to $CFG->gdversion, GD PHP extension is now required

739* Formslib will now throw a developer warning if a PARAM_ type hasn't been set for elements which
740 need it. Please set PARAM_RAW explicitly if you do not want any cleaning.

MG
742 in lib/coursecatlib.php, functions responsible for rendering courses and categories lists are
743 moved to course/renderer.php. The following global functions are deprecated: make_categories_list(),
6e1d1ee0 744 category_delete_move(), category_delete_full(), move_category(), course_category_hide(),
8db5dcb7 745 course_category_show(), get_course_category(), create_course_category(), get_all_subcategories(),

748 print_courses(), print_course(), get_category_courses_array(), get_category_courses_array_recursively(),
749 get_courses_wmanagers()
750 See http://docs.moodle.org/dev/Courses_lists_upgrade_to_2.5
0e2ca62e 751* $core_renderer->block_move_target() changed to support more verbose move-block-here descriptions.

RT
752* Additional (optional) param $onlyactive has been added to get_enrolled_users, count_enrolled_users
753 functions to get information for only active (excluding suspended enrolments) users. Included two
754 helper functions extract_suspended_users, get_suspended_userids to extract suspended user information.
e87214bd 755* The core_plugin_manager class now provides two new helper methods for getting information
d7d48b40 756 about known plugins: get_plugins_of_type() and get_subplugins_of_plugin().
e87214bd 757* The get_uninstall_url() method of all subclasses of \core\plugininfo\base class is now expected
73658371
DM
758 to always return moodle_url. Subclasses can use the new method is_uninstall_allowed()
759 to control the availability of the 'Uninstall' link at the Plugins overview page (previously
760 they would do it by get_uninstall_url() returning null). By default, URL to a new general plugin
761 uninstall tool is returned. Unless the plugin type needs extra steps that can't be handled by
762 plugininfo_xxx::uninstall() method or xmldb_xxx_uninstall() function, this default URL should
763 satisfy all plugin types.

772* M.util.help_icon has been deprecated. Code should be updated to use moodle-core-popuphelp
773 instead. To do so, remove any existing JS calls to M.util.help_icon from your PHP and ensure
774 that your help link is placed in a span which has the class 'helplink'.
