AG
4=== 2.8 ===
5
6* lib/excelllib.class.php has been updated. The class MoodleExcelWorkbook will now only produce excel 2007 files.
ebdcb292
SH
7* renderers: We now remove the suffix _renderable when looking for a render method for a renderable.
8 If you have a renderable class named like "blah_renderable" and have a method on a renderer named "render_blah_renderable"
9 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 10* New functions get_course_and_cm_from_cmid($cmorid, $modulename) and
11 get_course_and_cm_from_instance($instanceorid, $modulename) can be used to
12 more efficiently load these basic data objects at the start of a script.
13* New function cm_info::create($cm) can be used when you need a cm_info
14 object, but have a $cm which might only be a standard database record.

16DEPRECATIONS:
17* completion_info->get_incomplete_criteria() is deprecated and will be removed in Moodle 3.0.

2b55cb1b
RT
22* setnew_password_and_mail() and update_internal_user_password() will trigger
23 \core\event\user_password_updated. Previously they used to generate
24 \core\event\user_updated event.
25* update_internal_user_password() accepts optional boolean $fasthash for fast
26 hashing.
27* user_update_user() and user_create_user() api's accept optional param
28 $triggerevent to avoid respective events to be triggred from the api's.

a4582a51 66DEPRECATIONS:
994e5662 67* $module uses in mod/xxx/version.php files is now deprecated. Please use $plugin instead. It will be removed in Moodle 2.10.
3345e24f 68* Update init methods in all event classes - "level" property was renamed to "edulevel", the level property is now deprecated.
c4b0d6dc 69* Abstract class \core\event\course_module_instances_list_viewed is deprecated now, use \core\event\instances_list_viewed instead.
e1b16f97 70* Abstract class core\event\content_viewed has been deprecated. Please extend base event or other relevant abstract class.
45faf15d
AA
71* mod_book\event\instances_list_viewed has been deprecated. Please use mod_book\event\course_module_instance_list_viewed instead.
72* mod_chat\event\instances_list_viewed has been deprecated. Please use mod_chat\event\course_module_instance_list_viewed instead.
73* mod_choice\event\instances_list_viewed has been deprecated. Please use mod_choice\event\course_module_instance_list_viewed instead.
74* mod_feedback\event\instances_list_viewed has been deprecated. Please use mod_feedback\event\course_module_instance_list_viewed instead.
75* mod_page\event\instances_list_viewed has been deprecated. Please use mod_page\event\course_module_instance_list_viewed instead.
1f1a8f03 76* The constants FRONTPAGECOURSELIST, FRONTPAGETOPICONLY & FRONTPAGECOURSELIMIT have been removed.
8d1f33e1 77* Conditional availability API has moved and changed. The condition_info class is
78 replaced by \core_availability\info_module, and condition_info_section by
79 \core_availability\info_section. (Code that uses the old classes will generally
80 still work.)
81* coursemodule_visible_for_user() has been deprecated but still works - replaced
82 by a new static function \core_availability\info_module::is_user_visible()
83* cm_info::is_user_access_restricted_by_conditional_access has been deprecated
84 but still works (it has never done what its name suggests, and is
85 unnecessary).
86* cm_info and section_info property showavailability has been deprecated, but
87 still works (with the caveat that this information is now per-user).
88* cm_info and section_info properties availablefrom and availableuntil have been
89 deprecated and always return zero (underlying data doesn't have these values).
90* section_info property groupingid has been deprecated and always returns zero,
91 same deal.
07e78d93
DP
92* Various cm_info methods have been deprecated in favour of their read-only properties (get_url(), get_content(), get_extra_classes(),
93 get_on_click(), get_custom_data(), get_after_link, get_after_edit_icons)
af64bc61 94* The ajaxenabled function has been deprecated and always returns true. All code should be fully functional in Javascript.
52dc1de7 95* count_login_failures() has been deprecated, use user_count_login_failures() instead. Refer MDL-42891 for details.
c4b0d6dc 96
8d1f33e1 97Conditional availability (activities and sections):
98* New conditional availability API in /availability, including new availability
99 condition plugins in /availability/condition. The new API is very similar with
100 regard to checking availability, but any code that modifies availability settings
101 for an activity or section is likely to need substantial changes.
102
5947ab33
AN
103YUI:
104 * The lightbox attribute for moodle-core-notification-dialogue has been
105 deprecated and replaced by the modal attribute. This was actually
106 changed in Moodle 2.2, but has only been marked as deprecated now. It
107 will be removed in Moodle 2.9.
0860dd78
AN
108 * When destroying any type of dialogue based on moodle-core-notification, the relevant content is also removed from
109 the DOM. Previously it was left orphaned.
5947ab33 110
a4582a51
AN
111JavaSript:
112 * The findChildNodes global function has been deprecated. Y.all should
113 be used instead.
1d98ca14
AN
114 * The callback argument to confirm_action and M.util.show_confirm_dialog has been deprecated. If you need to write a
115 confirmation which includes a callback, please use moodle-core-notification-confirmation and attach callbacks to the
116 events provided.
a4582a51 117
9843e5ec 118* New locking api and admin settings to configure the system locking type.
3b635513
DM
119* New "Time spent waiting for the database" performance metric displayed along with the
120 other MDL_PERF vars; the change affects both the error logs and the vars displayed in
121 the page footer.
cc033d48
MN
122* Changes in the tag API. The component and contextid are now saved when assigning tags to an item. Please see
123 tag/upgrade.txt for more information.
9843e5ec 124
9e19a0f0 125=== 2.6 ===
8e8891b7 126
cc8fecb5 127* Use new methods from core_component class instead of get_core_subsystems(), get_plugin_types(),
d0cac8b5
FM
128 get_plugin_list(), get_plugin_list_with_class(), get_plugin_directory(), normalize_component(),
129 get_component_directory() and get_plugin_list_with_file(). The names of the new methods are
130 exactly the same, the only differences are that core_component::get_plugin_types() now always returns
131 full paths and core_component::get_plugin_list() does not accept empty parameter any more.
d534708f 132* Use core_text::* instead of textlib:: and also core_collator::* instead of collatorlib::*.
af578aec 133* Use new function moodleform::mock_submit() to simulate form submission in unit tests (backported).
85b38061 134* New $CFG->localcachedir setting useful for cluster nodes. Admins have to update X-Sendfile aliases if used.
656250de
PS
135* MS SQL Server drivers are now using NVARCHAR(MAX) instead of NTEXT and VARBINARY(MAX) instead of IMAGE,
136 this change should be fully transparent and it should help significantly with add-on compatibility.
598a82c9
PS
137* The string manager classes were renamed. Note that they should not be modified or used directly,
138 always use get_string_manager() to get instance of the string manager.
aae18d2a 139* The ability to use an 'insecure' rc4encrypt/rc4decrypt key has been removed.
96f81ea3
PS
140* Use $CFG->debugdeveloper instead of debugging('', DEBUG_DEVELOPER).
141* Use set_debugging(DEBUG_xxx) when changing debugging level for current request.
d55f05ef 142* Function moveto_module() does not modify $mod argument and instead now returns the new module visibility value.
db5f2d33
DM
143* Use behat_selectors::get_allowed_text_selectors() and behat_selectors::get_allowed_selectors() instead of
144 behat_command::$allowedtextselectors and behat_command::$allowedselectors
ac2b2713 145* Subplugins are supported in admin tools and local plugins.
71ab7e51 146* file_packer/zip_packer API has been modified so that key functions support a new file_progress interface
147 to report progress during long operations. Related to this, zip_archive now supports an estimated_count()
148 function that returns an approximate number of entries in the zip faster than the count() function.
d872881f 149* Class cm_info no longer extends stdClass. All properties are read-only and calculated on first request only.
44ddd2a1 150* Class course_modinfo no longer extends stdClass. All properties are read-only.
64501eee
MG
151* Database fields modinfo and sectioncache in table course are removed. Application cache core/coursemodinfo
152 is used instead. Course cache is still reset, rebuilt and retrieved using function rebuild_course_cache() and
153 get_fast_modinfo(). Purging all caches and every core upgrade purges course modinfo cache as well.
154 If function get_fast_modinfo() is called for multiple courses make sure to include field cacherev in course
155 object.
3bcf6b3c
RT
156* Internal (noreply and support) user support has been added for sending/receiving message.
157 Use core_user::get_noreply_user() and core_user::get_support_user() to get noreply and support user's respectively.
158 Real users can be used as noreply/support users by setting $CFG->noreplyuserid and $CFG->supportuserid
137885b7 159* New function readfile_allow_large() in filelib.php for use when very large files may need sending to user.
e87214bd 160* Use core_plugin_manager::reset_caches() when changing visibility of plugins.
bde002b8
PS
161* Implement new method get_enabled_plugins() method in subplugin info classes.
162* Each plugin should include version information in version.php.
723a6e56 163* Module and block tables do not contain version column any more, use get_config('xx_yy', 'version') instead.
5fed8433 164* $USER->password field is intentionally unset so that session data does not contain password hashes.
38fc0130 165* Use core_shutdown_manager::register_function() instead of register_shutdown_function().
c858655d 166* New file packer for .tar.gz files; obtain by calling get_file_packer('application/x-gzip'). Intended initially
167 for use in backup/restore only, as there are limitations on supported filenames. Also new packer for
168 backups which supports both compression formats; get_file_packer('application/vnd.moodle.backup').
169* New optional parameter to stored_file::get_content_file_handle to open file handle with 'gzopen' instead
170 of 'fopen' to read gzip-compressed files if required.
6c679d15 171* update_internal_user_password() and setnew_password_and_mail() now trigger user_updated event.
b2858b91 172* Add thirdpartylibs.xml file to plugins that bundle any 3rd party libraries.
2dd8e935
DP
173* New class introduced to help auto generate zIndex values for modal dialogues. Class "moodle-has-zindex"
174 should set on any element which uses a non-default zindex and needs to ensure it doesn't show above a
175 dialogue.
0c431257
PS
176* $CFG->filelifetime is now used consistently for most file serving operations, the default was lowered
177 to 6 hours from 24 hours because etags and x-sendfile support should make file serving less expensive.
d61d3e82
RT
178* Date format locale charset for windows server will come from calendar type and for gregorian it will use
179 lang file.
2d5c7d50
FM
180* The library to interact with Box.net (class boxclient) is only compatible with their APIv1 which
181 reaches its end of life on the 14th of Dec. You should migrate your scripts to make usage of the
182 new class boxnet_client(). Note that the method names and return values have changed.
b404b1f4
AG
183* Settings pages are now possible for Calendar type plugins. Calendar type plugins that require a settings page to
184 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
185* The admin/tool/generator tool was overhauled to use testing data generators and the previous interface to create
186 test data was removed (it was not working correctly anyway). If you were using this tool you will probably need to
187 update your code.

AN
298YUI:
299 * moodle-core-notification has been deprecated with a recommendation of

78686995
AN
301 transport costs. Current subclasses include:
302 * dialogue

304 * confirm
305 * exception

PS
308Event triggering and event handlers:
309 * All existing events and event handlers should be replaced by new
310 event classes and matching new event observers.
311 * See http://docs.moodle.org/dev/Event_2 for more information.
861b0510
FM
312 * The following events will be entirely removed, though they can still
313 be captured using handlers, but they should not be used any more.
314 * groups_members_removed -> \core\event\group_member_removed
315 * groups_groupings_groups_removed -> (no replacement)
316 * groups_groups_deleted -> \core\event\group_deleted

f0f0e1fe 319
a2602457 320=== 2.5.1 ===
321
322* New get_course() function for use when obtaining the course record from database. Will
323 reuse existing $COURSE or $SITE globals if possible to improve performance.
324
9a36be73
MG
325=== 2.5 ===
326
bae2846c
EL
327* The database drivers (moodle_database and subclasses) aren't using anymore the ::columns property
328 for caching database metadata. MUC (databasemeta) is used instead. Any custom DB driver should
329 apply for that change.
cedc656b
EL
330* The cron output has been changed to include time and memory usage (see cron_trace_time_and_memory()),
331 so any custom utility relying on the old output may require modification.
6b219310
DW
332* Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
333 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
334 an option for 0 bytes. Existing code that was replacing the 0 option in the return
335 from this function with a more sensible message, can now use the return from this function directly.
9a36be73 336* Functions responsible for output in course/lib.php are deprecated, the code is moved to
b1c2fc65
MG
337 appropriate renderers: print_section(), print_section_add_menus(), get_print_section_cm_text(),
338 make_editing_buttons()
9a36be73
MG

343* The function delete_course_module was deprecated and has been replaced with
344 course_delete_module. The reason for this was because the function delete_course_module
345 only partially deletes data, so wherever it was called extra code was needed to
346 perform the whole deletion process. The function course_delete_module now takes care
347 of the whole process.

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

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

377 functions to get information for only active (excluding suspended enrolments) users. Included two
378 helper functions extract_suspended_users, get_suspended_userids to extract suspended user information.
e87214bd 379* The core_plugin_manager class now provides two new helper methods for getting information
d7d48b40 380 about known plugins: get_plugins_of_type() and get_subplugins_of_plugin().
e87214bd 381* The get_uninstall_url() method of all subclasses of \core\plugininfo\base class is now expected
73658371
DM
382 to always return moodle_url. Subclasses can use the new method is_uninstall_allowed()
383 to control the availability of the 'Uninstall' link at the Plugins overview page (previously
384 they would do it by get_uninstall_url() returning null). By default, URL to a new general plugin
385 uninstall tool is returned. Unless the plugin type needs extra steps that can't be handled by
386 plugininfo_xxx::uninstall() method or xmldb_xxx_uninstall() function, this default URL should
387 satisfy all plugin types.
