+Feature: #97384 - TCA option "nullable"
+=======================================
+
+See :issue:`97384`
+
+Description
+===========
+
+In order to further thin out the TCA :php:`eval` option, the `null` value has
+been extracted into its own option: :php:`nullable`, which is a `boolean` value.
+
+Example:
+
+..  code-block:: php
+
+    'columns' => [
+       'nullable_column' => [
+           'title' => 'A nullable field',
+           'config' => [
+               'nullable' => true,
+               'eval' => 'trim',
+           ],
+       ],
+    ],
+
+Impact
+======
+
+It is now possible to define TCA fields as nullable by setting the
+:php:`nullable` option to :php:`true`. The database field should have the
+according :sql:`NULL` option set.
