- A new method, get_deprecated_icons(), has been added to the icon_system class. All deprecated icons should be registered through this method. Plugins can implement a callback to pluginname_get_deprecated_icons() to register their deprecated icons too.

  For more information see [MDL-82066](https://tracker.moodle.org/browse/MDL-82066)

#### Fixed

- All the setup and tear down methods of `PHPUnit` now are required to, always, call to their parent counterparts. This is a good practice to avoid future problems, especially when updating to PHPUnit >= 10.
  This includes the following methods:
    - `setUp()`
    - `tearDown()`
    - `setUpBeforeClass()`
    - `tearDownAfterClass()`

  For more information see [MDL-81523](https://tracker.moodle.org/browse/MDL-81523)

  For more information see [MDL-82466](https://tracker.moodle.org/browse/MDL-82466)
- Methods add_columns_from_entity(), add_filters_from_entity() and report_element_search() have been moved from \core_reportbuilder\datasource class to \core_reportbuilder\base class in order to be available also for system reports

    - `number`

  For more information see [MDL-81168](https://tracker.moodle.org/browse/MDL-81168)
- The base datasource `add_all_from_entities` method accepts a new optional parameter to specify which entities to add elements from

  For more information see [MDL-81330](https://tracker.moodle.org/browse/MDL-81330)
- All time related code has been updated to the PSR-20 Clock interface, as such the following methods no longer accept a `$timenow` parameter (instead please use `\core\clock` dependency injection):
  - `core_reportbuilder_generator::create_schedule`
  - `core_reportbuilder\local\helpers\schedule::[create_schedule|calculate_next_send_time]`

  For more information see [MDL-82041](https://tracker.moodle.org/browse/MDL-82041)

  For more information see [MDL-82133](https://tracker.moodle.org/browse/MDL-82133)

### mod_assign

#### Added

- Added 2 new settings:
    - `mod_assign/defaultgradetype`
      - The value of this setting dictates which of the GRADE_TYPE_X constants is the default option when creating new instances of the assignment.
      - The default value is GRADE_TYPE_VALUE (Point)
    - `mod_assign/defaultgradescale`
      - The value of this setting dictates which of the existing scales is the default option when creating new instances of the assignment.

  For more information see [MDL-54105](https://tracker.moodle.org/browse/MDL-54105)
- A new default value for `attemptreopenmethod` has been set to "Automatically until pass".

  For more information see [MDL-80741](https://tracker.moodle.org/browse/MDL-80741)

#### Removed

- The default option "Never" for `attemptreopenmethod` setting, which disallowed multiple attempts at the assignment, has been removed. This option was unnecessary because limiting attempts to 1 through the `maxattempts` setting achieves the same behavior.

  For more information see [MDL-80741](https://tracker.moodle.org/browse/MDL-80741)

#### Deprecated

- The constant `ASSIGN_ATTEMPT_REOPEN_METHOD_NONE` has been deprecated, and a new default value for `attemptreopenmethod` has been set to "Automatically until pass".

### core_role

#### Added

- Move all session management to the \core\session\manager class.
  This removes the dependancy to use the "sessions" table.
  Session management plugins (like redis) now need to inherit
  the base \core\session\handler class which implements
  SessionHandlerInterface and override methods as required.
  The following methods in \core\session\manager have been deprecated:
  * kill_all_sessions use destroy_all instead
  * kill_session use destroy instead
  * kill_sessions_for_auth_plugin use destroy_by_auth_plugin instead
  * kill_user_sessions use destroy_user_sessions instead

### qbank_managecategories

#### Deprecated

- question_category_list and question_category_list_item are no longer used, and are deprecated. Category lists are now generated by templates.

  For more information see [MDL-72397](https://tracker.moodle.org/browse/MDL-72397)
- The methods `question_is_only_child_of_top_category_in_context`, `question_is_top_category` and `question_can_delete_cat` from `qbank_managecategories\helper` class have been deprecated and moved to the `\core_question\category_manager` class, minus the misleading `question_` prefix. Following the creation of this class, it does not make sense for them to live inside the `qbank_managecategories` plugin.

  For more information see [MDL-72397](https://tracker.moodle.org/browse/MDL-72397)
- `qbank_managecategories\question_category_object` is now completely deprecated. Its methods have either been migrated to `qbank_managecategories\question_categories`, `core_question\category_manager`, or are no longer used at all.

  For more information see [MDL-72397](https://tracker.moodle.org/browse/MDL-72397)

#### Changed

- The methods in the `question_category_object` class that are still required following this change have been split between `\qbank_managecategories\question_categories` (for the parts used within this plugin for display a list of categories) and `\core_question\category_manager` (for the parts used for generate CRUD operations on question categories, including outside of this plugin). This will allow `question_category_object` to be deprecated, and avoids other parts of the system wishing to manipulate question categories from having to violate cross-component communication rules.

  For more information see [MDL-72397](https://tracker.moodle.org/browse/MDL-72397)

### core_form

#### Added

- Previously, the 'duration' form field type would allow users to input positive or negative durations. However looking at all the uses, everyone was expecting this input type to only accept times >= 0 seconds, and almost no-one was bothering to write manual form validation, leading to subtle bugs. So now, by default this field type will validate the input value is not negative. If you need the previous behaviour, there is a new option 'allownegative' which you can set to true. (The default is false.)
