+Feature: #95065 - New PSR-14 BootCompletedEvent
+===============================================
+
+See :issue:`95065`
+
+Description
+===========
+
+A new PSR-14 event :php:`\TYPO3\CMS\Core\Core\Event\BootCompletedEvent` has been added to TYPO3
+Core. This event is fired on every request when TYPO3 has been
+fully booted, right after all configuration files have been added.
+
+This new Event complements the :php:`\TYPO3\CMS\Core\Configuration\Event\AfterTcaCompilationEvent` which
+is executed after TCA configuration has been assembled.
+
+Registration of the Event in your extensions' :file:`Services.yaml`:
+
+.. code-block:: yaml
+
+  MyVendor\MyPackage\Bootstrap\MyEventListener:
+    tags:
+      - name: event.listener
+        identifier: 'my-package/my-listener'
+
+.. code-block:: php
+
+    class MyEventListener {
+        public function __invoke(BootCompletedEvent $e): void
+        {
+            // do your magic
+        }
+    }
+
+
+Impact
+======
+
+Use cases for this event is to alter or to boot up extensions'
+code which needs to be executed at any time, and needs
+TYPO3's full configuration including all loaded extensions.
