# core (subsystem) Upgrade notes
## 4.5.1+
### Added
- A new core\ip_utils::normalize_internet_address() method is created to sanitize an IP address, a range of IP addresses, a domain name or a wildcard domain matching pattern.
Moodle previously allowed entries such as 192.168. or .moodle.org for certain variables (eg: $CFG->proxybypass). Since MDL-74289, these formats are no longer allowed. This method converts this informations into an authorized format. For example, 192.168. becomes 192.168.0.0/16 and .moodle.org becomes *.moodle.org.
Also a new core\ip_utils::normalize_internet_address_list() method is created. Based on core\ip_utils::normalize_internet_address(), this method normalizes a string containing a series of Internet addresses.
For more information see [MDL-79121](https://tracker.moodle.org/browse/MDL-79121)
### Changed
- The `core_renderer::tag_list` function now has a new parameter named `displaylink`. When `displaylink` is set to `true`, the tag name will be displayed as a clickable hyperlink. Otherwise, it will be rendered as plain text.
For more information see [MDL-75075](https://tracker.moodle.org/browse/MDL-75075)
- The following test classes have been moved into autoloadable locations:
| Old location | New classname |
| --- | --- |
| `\core\tests\route_testcase` | `\core\tests\router\route_testcase` |
| `\core\router\mocking_route_loader` | `\core\tests\router\mocking_route_loader` |
For more information see [MDL-83968](https://tracker.moodle.org/browse/MDL-83968)
## 4.5.1
### Added
- `\core\output\activity_header` now uses the `is_title_allowed()` method when setting the title in the constructor.
This method has been improved to give priority to the 'notitle' option in the theme config for the current page layout, over the top-level option in the theme.
For example, the Boost theme sets `$THEME->activityheaderconfig['notitle'] = true;` by default, but in its `secure` pagelayout, it has `'notitle' = false`.
This prevents display of the title in all layouts except `secure`.
For more information see [MDL-75610](https://tracker.moodle.org/browse/MDL-75610)
### Changed
- All uses of the following PHPUnit methods have been removed as these methods are
deprecated upstream without direct replacement:
- `withConsecutive`
- `willReturnConsecutive`
- `onConsecutive`
Any plugin using these methods must update their uses.
For more information see [MDL-81308](https://tracker.moodle.org/browse/MDL-81308)
## 4.5
### Added
- A new method, `\core_user::get_name_placeholders()`, has been added to return an array of user name fields.
For more information see [MDL-64148](https://tracker.moodle.org/browse/MDL-64148)
- The following classes have been renamed and now support autoloading.
Existing classes are currently unaffected.
| Old class name | New class name |
| --- | --- |
| `\core_component` | `\core\component` |
For more information see [MDL-66903](https://tracker.moodle.org/browse/MDL-66903)
- Added the ability for unit tests to autoload classes in the `\[component]\tests\`
namespace from the `[path/to/component]/tests/classes` directory.
For more information see [MDL-66903](https://tracker.moodle.org/browse/MDL-66903)
- Added a helper to load fixtures from a components `tests/fixtures/` folder:
```php
advanced_testcase::load_fixture(string $component, string $fixture): void;
```
For more information see [MDL-66903](https://tracker.moodle.org/browse/MDL-66903)
- Redis session cache has been improved to make a single call where two were used before.
For more information see [MDL-69684](https://tracker.moodle.org/browse/MDL-69684)
- Added stored progress bars
For more information see [MDL-70854](https://tracker.moodle.org/browse/MDL-70854)
- Two new functions have been introduced in the `\moodle_database` class:
- `\moodle_database::get_counted_records_sql()`
- `\moodle_database::get_counted_recordset_sql()`
These methods are compatible with all databases.
They will check the current running database engine and apply the `COUNT` window function if it is supported,
otherwise, they will use the usual `COUNT` function.
The `COUNT` window function optimization is applied to the following databases:
- PostgreSQL
- MariaDB
- Oracle
Note: MySQL and SQL Server do not use this optimization due to insignificant performance differences before and
after the improvement.
For more information see [MDL-78030](https://tracker.moodle.org/browse/MDL-78030)
- The `after_config()` callback has been converted to a hook, `\core\hook\after_config`.
For more information see [MDL-79011](https://tracker.moodle.org/browse/MDL-79011)
- The `\core\output\select_menu` widget now supports rendering dividers between menu options. Empty elements (`null` or empty strings) within the array of options are considered and rendered as dividers in the dropdown menu.
For more information see [MDL-80747](https://tracker.moodle.org/browse/MDL-80747)
- The `\core\output\select_menu` widget now supports a new feature: inline labels. You can render the label inside the combobox widget by passing `true` to the `$inlinelabel` parameter when calling the `->set_label()` method.
For more information see [MDL-80747](https://tracker.moodle.org/browse/MDL-80747)
- A new hook called `\core\hook\output\after_http_headers` has been created. This hook allow plugins to modify the content after headers are sent.
For more information see [MDL-80890](https://tracker.moodle.org/browse/MDL-80890)
- The following classes have been renamed.
Existing classes are currently unaffected.

For more information see [MDL-81282](https://tracker.moodle.org/browse/MDL-81282)
- Added a new `exception` L2 Namespace to APIs.
For more information see [MDL-81903](https://tracker.moodle.org/browse/MDL-81903)
- Added a mechanism to support autoloading of legacy class files.
This will help to reduce the number of `require_once` calls in the codebase, and move away from the use of monolithic libraries.
For more information see [MDL-81919](https://tracker.moodle.org/browse/MDL-81919)
- The following exceptions are now also available in the `\core\exception` namespace:
- `\coding_exception`
- `\file_serving_exception`
- `\invalid_dataroot_permissions`

For more information see [MDL-82183](https://tracker.moodle.org/browse/MDL-82183)
- A new method, `\core\output\::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.
When `$CFG->debugpageinfo` is enabled, a console message will display a list of the deprecated icons.
For more information see [MDL-82212](https://tracker.moodle.org/browse/MDL-82212)
- Two new optional parameters have been added to the `\core\output\notification` constructor:
