+Feature: #82441 - Inject logger when creating objects
+=====================================================
+
+See :issue:`82441`
+
+Description
+===========
+
+Classes that implement :php:`\Psr\Log\LoggerAwareInterface` automatically
+get a logger instance injected when a class instance is created via
+:php:`GeneralUtility::makeInstance()` and :php:`ObjectManger::get()`.
+
+For developer convenience the :php:`\Psr\Log\LoggerAwareTrait` can be used.
+The trait adds a public :php:`setLogger()` and a protected :php:`$logger` property
+to the class, no further code is needed to successfully implement the interface.
+
+A minimal example looks like this (example from a test case fixture):
+
+.. code-block:: php
+
+    <?php
+    declare(strict_types = 1);
+    namespace TYPO3\CMS\Core\Tests\Unit\Utility\Fixtures;
+
+    use Psr\Log\LoggerAwareInterface;
+    use Psr\Log\LoggerAwareTrait;
+
+    class GeneralUtilityMakeInstanceInjectLoggerFixture implements LoggerAwareInterface
+    {
+        use LoggerAwareTrait;
+    }
+
+.. index:: PHP-API
