EL
6* The cron output has been changed to include time and memory usage (see cron_trace_time_and_memory()),
7 so any custom utility relying on the old output may require modification.
6b219310
DW
8* Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
9 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
10 an option for 0 bytes. Existing code that was replacing the 0 option in the return
11 from this function with a more sensible message, can now use the return from this function directly.
9a36be73
MG
12* Functions responsible for output in course/lib.php are deprecated, the code is moved to
13 appropriate renderers: print_section_add_menus()
14 See functions' phpdocs in lib/deprecatedlib.php
15* Function get_print_section_cm_text() is deprecated, replaced with methods in cm_info
3cb856c7
PS
16* zip_packer may create empty zip archives, there is a new option to ignore
17 problematic files when creating archive
93cc145f
MN
18* The function delete_course_module was deprecated and has been replaced with
19 course_delete_module. The reason for this was because the function delete_course_module
20 only partially deletes data, so wherever it was called extra code was needed to
21 perform the whole deletion process. The function course_delete_module now takes care
22 of the whole process.
91c8cf99
F
23* curl::setopt() does not accept constant values any more. As it never worked properly,
24 we decided to make the type check stricter. Now, the keys of the array pass must be a string
25 corresponding to the curl constant name.
043f1005
RT
26* Function get_users_listing now return list of users except guest and deleted users. Previously
27 deleted users were excluded by get_users_listing. As guest user is not expected while browsing users,
28 and not included in get_user function, it will not be returned by get_users_listing.
1c14b1c1
DW
29* The add_* functions in course/dnduploadlib.php have been deprecated. Plugins should be using the
30 MODNAME_dndupload_register callback instead.
690a55f6
DM
31* The signature of the add() method of classes implementing the parentable_part_of_admin_tree
32 interface (such as admin_category) has been extended. The new parameter allows the caller
33 to prepend the new node before an existing sibling in the admin tree.
87b6981e
EL
34* condition_info:get_condition_user_fields($formatoptions) now accepts the optional
35 param $formatoptions, that will determine if the field names are processed by
36 format_string() with the passed options.
689096bc 37* remove all references to $CFG->gdversion, GD PHP extension is now required
b45ba7f6
DP
38* Formslib will now throw a developer warning if a PARAM_ type hasn't been set for elements which
39 need it. Please set PARAM_RAW explicitly if you do not want any cleaning.

09ae7ee0
MG
41 in lib/coursecatlib.php, functions responsible for rendering courses and categories lists are
42 moved to course/renderer.php. The following global functions are deprecated: make_categories_list(),
6e1d1ee0 43 category_delete_move(), category_delete_full(), move_category(), course_category_hide(),
8db5dcb7 44 course_category_show(), get_course_category(), create_course_category(), get_all_subcategories(),

0e2ca62e 50* $core_renderer->block_move_target() changed to support more verbose move-block-here descriptions.
38c1dd19
RT
51* Additional (optional) param $onlyactive has been added to get_enrolled_users, count_enrolled_users
52 functions to get information for only active (excluding suspended enrolments) users. Included two
53 helper functions extract_suspended_users, get_suspended_userids to extract suspended user information.
d7d48b40
DM
54* The plugin_manager class now provides two new helper methods for getting information
55 about known plugins: get_plugins_of_type() and get_subplugins_of_plugin().

77a5c093
PS
