BREAKING

Behavior Changes

Filter Execution Order

The order in which Controller Filters are executed has changed. See :ref:`Upgrading Guide <upgrade-450-filter-execution-order>` for details.

Nested Route Groups and Options

Due to a bug fix, the behavior has changed so that options passed to the outer group() are merged with the options of the inner group(). See :ref:`Upgrading Guide <upgrade-450-nested-route-groups-and-options>` for details.

Others

• Logger: The :php:func:`log_message()` function and the logger methods in CodeIgniter\Log\Logger now do not return bool values. The return types have been fixed to void to follow the PSR-3 interface.

Interface Changes

Note

As long as you have not extended the relevant CodeIgniter core classes or implemented these interfaces, all these changes are backward compatible and require no intervention.

• Logger: The psr/log package has been upgraded to v2.0.0.

Method Signature Changes

Return Type Changes

• Model: The return type of the objectToRawArray() method in the Model and BaseModel classes has been changed from ?array to array.

Others

• Logger: The method signatures of the methods in CodeIgniter\Log\Logger that implements the PSR-3 interface have been fixed. The bool return types are changed to void. The $message parameters now have string|Stringable types.

Removed Deprecated Items

Filters

• The following deprecated items have been removed, because now :ref:`multiple-filters` are always enabled.

  • Filters::enableFilter()
  • RouteCollection::getFilterForRoute()
  • Router::$filterInfo
  • Router::getFilter()

Enhancements

Commands

• Added spark lang:find command to update translations keys. See :ref:`generating-translation-files-via-command` for the details.

Testing

• DomParser: The new methods were added seeXPath() and dontSeeXPath() which allows users to work directly with DOMXPath object, using complex expressions.

Forge

Others

Model

Libraries

Helpers and Functions

Others
