+=======================================
+Feature: #78899 - TCA maxitems optional
+=======================================
+
+See :issue:`78899`
+
+Description
+===========
+
+The :code:`TCA` config setting :code:`maxitems` for :code:`type=select` and :code:`type=group` fields is now an optional setting that defaults to a high value (99999) instead of 1 as before.
+
+
+Impact
+======
+
+Fields that typically relate to multiple relations like the group element and some select elements no longer need :code:`maxitems` set to some value to enable multiple values.
+
+Example before:
+
+.. code-block:: php
+
+    aField => [
+        'config' => [
+            'type' => `select',
+            'renderType' => 'multipleSideBySide',
+            'maxitems' => 99999,
+        ],
+    ],
+
+Example after:
+
+.. code-block:: php
+
+    aField => [
+        'config' => [
+            'type' => `select',
+            'renderType' => 'multipleSideBySide',
+        ],
+    ],
+
+This simplifies :code:`TCA` of those fields and removes a cross dependency between :code:`renderType` and :code:`maxitems`.
